The concepts of ‘health’ and ‘disease’.
Francisca Stutzin Donoso .
This chapter provides an overview of the problem of conceptual definition of ‘health’ and ‘disease’ as a background to situate and introduce the discussion about health outcomes and value of new medical interventions. This work reflects and discusses broader literature on this topic by highlighting the available – and lacking – definitions in the specific context of health institutions in the UK. After introducing the World Health Organization's (WHO) definition of ‘health’ and some general criticisms of it, two more recent and particularly relevant positive definitions of ‘health’ are presented, stressing the potential connection between such definitions and the role of healthcare services. This is followed by a more extensive analysis of positive definitions of ‘disease’ since the technical literature seems particularly prolific and relevant. In order to organise the discussion, this chapter frames the different approaches to positive definitions of ‘disease’ within the fact/value problem. At the same time that it introduces three of the most influential conceptualisations of disease (Biostatistical Theory, The APA Task Force work and the Harm Dysfunction Analysis), it illustrates three possible positions regarding the fact/value problem in this matter (strong descriptivism, strong normativism, and mixed descriptive/normativism, respectively). Finally, because of the lack of a successful and agreed definition of ‘disease’, this chapter highlights recent efforts to embrace the disjunctive and vague elements of this concept, allowing and encouraging specific and contextual cluster definitions of ‘disease’, which seem particularly useful to contextualise and open the discussion on how to think about the idea of health outcomes and value in medical interventions.
Conceptual constructs tend to become naturalised and their meanings are taken for granted in the work to push disciplines further. Although this might be necessary to some extent, keeping in mind the frailty of conceptual definitions may be just as important for disciplines to move forward without oversimplifying or lacking context and complexity. Thus, by taking a step back and focusing on the question of what is value in the context of new medical interventions, this book highlights the importance of conceptual discussions in the background of highly applied fields associated with healthcare delivery which face challenging practical decisions of prioritisation, resource allocation and conflicting goals.
preventing people from dying prematurely
enhancing the quality of life for people with long-term conditions
helping people to recover from episodes of ill health or following injury
ensuring that people have a positive experience of care
treating and caring for people in a safe environment and protecting them from avoidable harm ( NHS, 2020 ).
Although analysing these dimensions in-depth goes beyond the scope of this work, acknowledging this framework serves the purpose of showing how sanitary goals and health outcomes can potentially raise tensions when prioritising.
It is clearly unfeasible to pursue all these outcomes simultaneously and some may come into direct conflict with one another. A good example of this is how sometimes enhancing the quality of life of someone living with a long-term condition may imply that it is not possible to prevent that person from dying prematurely. 1
Complexities associated with this are in direct connection with their immediate conceptual context, i.e. the concepts of ‘health’ and ‘disease’ to which this chapter is dedicated. Academic discussion around these two underlying concepts in all health-related issues is highly prolific and still unresolved. Usually taken for granted, one could claim these concepts may be central to defining when, how and with which goals medical interventions should be developed and applied, framing and contributing to the overarching focus of this book: exploring different definitions and approaches to value and how to incorporate these into the assessment of new medical interventions.
This chapter will argue that there needs to be a clear rationale connecting the concepts of ‘health’ (and ‘disease’), health outcomes and the value of medical interventions to have consistent systems with clear and achievable goals in which results or measurements can actually be put into context and offer valuable input. We will see how this core idea underlies most of the problems presented in this book. 2
The concepts of ‘health’ and ‘disease’ play an important part in everyone's daily experience of being alive and still manage to escape the descriptive possibilities of language – puzzling philosophers of science, sociologists, psychologists and many others, these concepts somehow invite Augustine's reflection on the question of “what, then, is time?” – so sensibly highlighted by Ricoeur in the preface to Time and Narrative, “I know well enough what it is, provided that nobody asks me; but if I am asked what it is and I try to explain, I am baffled” (Saint Augustin in Ricoeur, 1984, p. xi). Very similarly, addressing the concepts of ‘health’ and ‘disease’ implies engaging in an ongoing quest.
The current Constitution of the NHS in the UK, last updated in 2015, does not define what counts as health or disease. However, it does state that the NHS’ aims to improve health and well-being, supporting people to keep mentally and physically well, to help them get better when they are ill and, if they cannot fully recover, help them to stay as well as possible till the end of their lives ( NHS, 2015 ). It is possible to see from this statement that the core idea underlying the use of the concept of ‘health’ mirrors a positive definition 3 based on a state of well-being that includes both a mental and physical dimension. The UK's National Institute for Health and Care Excellence (NICE) does not define health specifically but health-related quality of life as “a combination of a person's physical, mental and social well-being; not merely the absence of disease” ( NICE, 2018 ). The NICE definition paraphrases one stated in and enforced by the WHO Constitution, according to which, “health is a state of complete physical, mental and social wellbeing and not merely the absence of disease or infirmity” ( WHO, 1948 ). In this manner, the UK seems to embrace a positive understanding of health, rejecting negative definitions based on the absence of disease.
The overall assessment of the definition offered by the WHO proposes that by suggesting a positive operationalisation of the concept of ‘health’, it represents an improvement over previous negative definitions, but it, nonetheless, raises significant problems. These are mostly related to the idea of “complete well-being”, which NICE omits.
Critical views on the definition offered by the WHO raise issues particularly relevant for the topic of this book. Some critiques suggest that it seems idealistic and unachievable, labelling most of the population as unhealthy most of the time. Critiques argue that this definition could contribute to the medicalisation of society, justify unlimited development of drugs or treatments, and create serious challenges for healthcare systems that have to find a balance between individual health needs and the resources available. Further critiques of this definition are related to disease patterns shifting from acute to chronic conditions, supporting the idea that conceptualisations of health and disease might be closely related to historical context and associated health developments. Additional critiques of this definition include, among many others, problems for disease classifications systems (e.g. quality of life, disability, functioning) since health, as “complete” well-being, does not allow for measurement or operational specification ( Bircher, 2005 ; Huber et al., 2011 ).
In all critiques, these considerations work to bridge the gap between the relevant conceptualisations of health and disease and define the value of medical interventions. Broadly speaking, if the value of medical interventions comes from a focus on improving the health and reducing the disease burden on individuals and populations, then what counts as ‘health’ and ‘disease’ matters.
a dynamic state of wellbeing characterized by a physical, mental and social potential, which satisfies the demands of a life commensurate with age, culture, and personal responsibility. If the potential is insufficient to satisfy these demands the state is disease. ( Bircher, 2005 , p. 336)
This definition seems to be an overall improvement of the definition offered by the WHO because it allows health to be a variable state within the lifespan of an individual, attending to relevant dimensions and being, in this sense, more realistic. However, this definition resorts to controversial or difficult concepts – mental and social potential and personal responsibility – that would also require a definition for this concept of ‘health’ to be practicable.
In contrast to this long-winded definition, Huber et al. ( 2011 , p. 2) define health as the “ability to adapt and self-manage”, with specific characterisations in the three domains of health: physical, mental and social. This understanding of health seems particularly interesting because it diverges completely from the WHO legacy, stressing the capacity or functioning of the individual, thus, potentially reconfiguring the role of healthcare services and the value of medical interventions in terms of support towards developing such functioning.
Furthermore, this definition may be particularly relevant in current times when chronic diseases are the main disease burden in the UK and the rest of the world. Chronic diseases currently account for 90 % of all deaths in the UK, and the risk of dying prematurely from a chronic disease is 11 % ( Office for National Statistics, 2017 ; WHO, 2017 ). 4 Furthermore, chronic diseases account for 50 % of all general practice appointments, 64 % of outpatient appointments, 70 % of all inpatient bed days and 70 % of the total health and care expenditure in England ( Department of Health, 2012 ). 5 This information implies that currently and in terms of disease burden, full recovery is not an option in most cases, therefore, self-management and the possibility to mobilise resources become key concepts in assessing the value of medical interventions ( Bodenheimer et al., 2002 ). This idea of self-management and the possibility to mobilise resources remains closely linked to the capabilities approach and its application to this field. 6
Regarding positive definitions of ‘disease’, those that do not merely place explanatory value on the absence of health, the overall picture is just as dynamic and unresolved. This discussion is very prolific both in terms of the literature generated and the many working definitions ( Lemoine, 2013 ; Walker and Rogers, 2018 ). However, specifically in the context of official health institutions in the UK, neither the NHS nor NICE acknowledges or defines of the concept of ‘disease’ or any other related concepts such as ‘disorder’, ‘condition’, ‘sickness’, ‘infirmity’ or ‘illness’. Therefore, it might be thought that such national institutions implicitly embrace a negative definition of ‘disease’ by setting their focus on health. In other words, ‘disease’ is broadly taken to be the absence of health.
As an effort to systematise the extensive literature on the concept of ‘disease’, Boorse ( 2011 ) suggests that there are five commonly present elements in most ‘health’ and ‘disease’ definitions. These elements include (1) medical treatment, (2) pain, discomfort and disability, (3) statistical abnormality, (4) disvalue and (5) specific biological ideas: homeostasis, fitness and adaptation. However, counter-examples for each of these elements show that all fail to be neither necessary nor sufficient for a satisfactory definition of these concepts at an abstract theoretical level, 7 thus, illustrating how challenging it seems to be to reach satisfactory definitions.
Traditional conceptual analysis in philosophy broadly implies aiming at an exact, descriptive definition by “testing a definitional criteria and exceptions against a set of given cases, while drawing up counter-cases against an opponent's definition”, thus, identifying conditions that are both necessary and sufficient to define a concept and the exceptions to these conditions ( Lemoine, 2013 , p. 310). However, because of the lack of a satisfactory descriptive definition of ‘health’ and ‘disease’, it has been argued that conceptual analysis can provide descriptive or naturalist (factual) definitions or normativist (value) definitions. The former are value-free definitional criteria, while the latter are value-laden definitional criteria, broadly assuming that disease is bad for the person and health is desirable. Although most authors provide some kind of normativist definitional criteria for ‘health’ and ‘disease’, which may be soft, in the sense that may also include some descriptive conditions, some very influential definitions adopt a strong descriptive approach, stressing the importance to continue working on value-free definitional criteria for ‘health’ and ‘disease’ ( Boorse, 2011 ; Lemoine, 2013 ).
In order to illustrate this very dynamic discussion and provide some background on what is the state-of-the-art, it seems relevant to present some of the most influential definitions of the concept of ‘disease’. These include Boorse's ( 1977 ) Biostatistical Theory, which represents a strong descriptivist (value-free) position, Spitzer and Endicott's ( 1978 ) tentative proposed definition and criteria of medical and mental disorder, which represents a rather normativist (value-laden) position, and Wakefield's ( 1992 ) Harm Dysfunction Analysis, which represents a mixed position, stressing the importance of naturalist and normativist components.
Boorse's ( 1977 ) Biostatistical Theory, being largely laden towards normativist definitions of ‘health’ and ‘disease’, emerges as a strong critique of previous literature on the topic. The author offers a strong descriptive definition, stressing that health and disease evaluations are sensitive to contextual and individual variables, highlighting that the conceptual definition should be value-free to allow the individual to value the condition according to relevant specific circumstances. In this manner, according to the Biostatistical Theory, ‘health’ is defined by normal functioning, where what is normal is statistically determined and functioning refers to biological functions. Furthermore, ‘disease’ consists of deviations from the species’ biological design, therefore, identifying ‘disease’ is considered a matter of natural sciences rather than an evaluative judgment. Thus, the overall rationale and assumptions underlying this definition imply four main criteria: (1) definition of the reference class (an age group of a sex of a species), (2) definition of normal function within members (based on a statistically typical contribution to the individual survival and reproduction), (3) definition of ‘health’ in a member of the reference class as a normal functional ability and (4) definition of ‘disease’ as an internal state which reduces functional abilities below typical efficiency ( Boorse, 1977 ).
a medical disorder is a relatively distinct condition resulting from an organismic dysfunction, which in its fully developed or extreme form is directly and intrinsically associated with distress, disability, or certain other types of disadvantage. The disadvantage may be of a physical, perceptual, sexual, or interpersonal nature. Implicitly there is a call for action on the part of the person who has the condition, the medical or its allied professions, and society. A mental disorder is a medical disorder whose manifestations are primarily signs or symptoms of psychological (behavioural) nature, or if physical, can be understood only using psychological concepts. ( Spitzer and Endicott, 1978 , p. 18)
Thus, this definition comprises three fundamental ideas within the notion of medical disorder, which altogether convey the overall message that something has gone wrong in the human organism. This gives special importance to the evaluative aspect of the concept: (1) negative consequences of the condition, (2) an inferred or identified organismic dysfunction, and (3) an implicit call for action to the medical profession, the person with the condition and the society in terms of granting exemptions from certain responsibilities to those in the sick role, as well as providing a means for delivery of medical care ( Spitzer and Endicott, 1978 ). It is important to note that these authors’ ultimate interest is to define the concept of ‘mental disorder’, and since they decide to do this by considering it a subgenre of medical disorders, they also provide a definition of ‘medical disorder’. However, because of this ultimate interest, the definition avoids using the word ‘disease’ as, according to these authors, it generally denotes a progressive physical disorder of known physiopathology, which is not the case for most mental disorders. Therefore, the concept of organismic dysfunction, or its negative consequences, do not imply that these have a physical nature ( Spitzer and Endicott, 1978 ). Although analysing this definition further goes beyond the interest of this revision, it is worth noting that the authors add a list of four criteria which, they argue, must be met in order for a condition to be classified as a disorder.
a condition is a disorder if and only if (a) the condition causes harm or deprivation of benefit to the person as judged by the standards of the person's culture (the value criterion), and (b) the condition results from the inability of some internal mechanisms to perform its natural function, wherein a natural function is an effect that is part of the evolutionary explanation of the existence and structure of the mechanism (the explanatory criterion). (1992, p. 384)
a condition is a mental disorder if and only if (a) the condition causes harm or deprivation of benefit to the person as judged by the standards of the person's culture (the value criterion), and (b) the condition results from the inability of some mental mechanisms to perform its natural function, wherein a natural function is an effect that is part of the evolutionary explanation of the existence and structure of the mental mechanism (the explanatory criterion). ( Wakefield, 1992 , p. 385)
However, as stated by this author, even the clearest concepts pose areas of vagueness and ambiguity, and, in this particular definition, this indeterminacy rests on how to distinguish mental from physical mechanisms ( Wakefield, 1992 ).
All these working definitions of the concept of ‘disease’ share the idea that there is a discontinuity between health and disease, i.e. health and disease can be either present or absent. Nonetheless, the concept of dysfunction – that all these definitions share – admits different degrees and, therefore, raises the problem of using a continuous variable (dysfunction) as the basis for a categorical definition. 9 This has been described as the line-drawing problem in ‘disease’ definition ( Rogers and Walker, 2017b ).
Building on various disease examples (cancer, UTI, TB), Rogers and Walker ( 2017b ) argue that the more the scientific community learns about what constitutes ‘disease’, the more difficult it is to determine the relevant dysfunction associated with a condition. As such, the absolute philosophical perspective on disease does not reflect everyday medical practice with borderline cases, drawing boundaries as necessary for decision-making and practical purposes. So, according to Walker and Rogers ( 2018 ), the concept of ‘disease’ does not seem to be classically structured since it fails to be defined in classical ways (conceptual analysis leading to exact necessary and sufficient conditions). Following from this, the authors suggest that this concept should be approached as a disjunctive and vague concept, therefore, encouraging the academic community to focus on developing specific and contextual cluster definitions for specific reasons or aims ( Walker and Rogers, 2018 ). 10
They should, where they can, act to ensure that their patients do adhere. Sometimes they cannot do this. But even in that situation there is often more they can do. They could, for example, switch the patient onto a different treatment plan, one she is more likely to adhere to. This is not, however, likely to be the best option. While it may be better for the patient than doing nothing, if the original treatment was preferred at the choice stage it is unlikely to be as beneficial as bringing it about that the patient adheres. ( Walker, 2019 , p. 141)
In this way, the goal of long-term treatment would focus on allowing patients to adhere even if this means prescribing a less effective treatment to which patients are more likely to adhere. This goal would be in line with an understanding of ‘health’ as the ability to adapt and self-manage ( Huber et al., 2011 ), potentially valuing a medical intervention to which patients are more likely to adhere over a more effective one to which patients are less likely to adhere.
will retain relevance only to the extent that they help us address real problems of these new disciplines. If they are of no discernible help, then it is best to ignore them for this case. ( Alexandrova, 2015 , p. 224)
This intrinsically flexible and contextual perspective may help us to understand and keep in mind the rigour required and the unavoidable complexity of working within the health sciences. 12 In this way, this book aims at embracing such complexity by comprising efforts from different disciplines and welcoming interdisciplinary works to address the question of what is value in the context of new medical interventions.
Parsons’ contribution in this book discusses this precisely. The author argues that all patients (including those who lack decision-making capacity) ought to sometimes forego dialysis in favour of conservative kidney management, prioritising their quality of life over life-extending treatment.
Chapters in this book, which refer to this conceptual consistency issue, are those by Buch et al. on highly-priced pharmaceuticals and by Steigenberger et al. on integrating patients’ and social aspects into Health Technology Assessments. In the first case, assessing whether certain pharmaceuticals are too expensive will depend heavily on what societies are willing to pay and this, in turn, might be argued to depend greatly on what the states of health and disease are. This latter point also applies to the second case, which focuses on patients’ perceived value of the quality and benefit of a health technology. More contributions in this book focused on economics, such as those by Himmler and Mitchell, exemplify and refer to this matter. These works use specific understandings and frameworks for the monetary value of health in terms of well-being, for example, those defined by a specific measurement of quality of life (quality-adjusted life years) (Himmler, in this volume). Mitchell's work (in this volume) challenges this notion, as the quality of life captured by quality-adjusted life years might be considered too narrow, suggesting a shift from outcomes focused on health (such as quality-adjusted life years) towards people's capabilities.
In general terms, this means a definition focused on what health is instead of what it is not. Health defined as the absence of disease, for example, is usually described as a negative definition of health.
These statistics are based on the four main groups of non-communicable chronic diseases (cardiovascular disease, cancer, diabetes and obstructive pulmonary disease).
These statistics are based on a category of chronic diseases that is not restricted to non-communicable diseases, though it includes the main four groups as well (cardiovascular disease, cancer, diabetes and obstructive pulmonary disease).
This is discussed in-depth later in this bood in the chapters by Mitchell – briefly mentioned previously – and Ubels, who highlights the importance of combining information about capability, functioning and utility in the assessment of the value of medical interventions.
Counter-examples for each element include (1) all disease for which there is no treatment available and, conversely, non-disease medical treatments, such as plastic surgery or contraceptive pills; (2) pathological conditions that do not involve pain, discomfort or disability, such as hypertension, and, conversely, non-pathological conditions that may involve all or some of these elements, such as pregnancy; (3) many statistically abnormal conditions are not diseases, such as being left-handed and, conversely, many statistically normal conditions involve a pathological condition such as gum disease or tooth decay; and (4) depending on the context, a disease may not necessarily be bad for the individual. An example of this would be that flat feet during a period of war might save someone's life by precluding them from joining the armed forces, thus, potentially being regarded as a good thing. Finally, (5) many non-disease human functions are not homeostatic, such as growth or reproduction, and, conversely, pathologies such as sterility do not produce any homeostatic failure. If one considers that fitness stands for individual survival and reproduction, many pathological conditions do not interfere with these, such as anosmia, and, conversely, many non-pathological activities, such as mountaineering, may increase the risk of early death. Regarding adaptation, depending on the context, some diseases may not be maladaptive. An example of this would be a severe immune deficiency in a sterile environment (plastic bubble) and, conversely, many non-pathological conditions may be adaptive in one context and not in another, such as being light-skinned in Iceland or in Africa (Boorse, 2011).
This means that what is causing the symptom arises from a mental dysfunction and not that the symptom is mental dysfunction. Some symptoms, such as pain, are argued to be a mental phenomenon, but somatic dysfunctions may be the cause of pain, in which case, pain is not a mental disorder. Therefore, what matters regarding labelling purposes is that the nature of the cause of the symptom is mental.
“Biological functions may categorically cease altogether (the heart may stop beating, the liver stop metabolising, and the kidneys stop filtering blood), but short of absolute cessation of function, there are degrees of performance all the way up to abundantly healthy levels” (Rogers and Walker, 2017b, p. 415).
An example of such cluster definitions is Roger and Walker's (2017a, p. 277) working definition of borderline diseases as “X is a disease ODx if there is a dysfunction that has significant risk of causing severe harm”.
Parsons’ chapter in this publication on quality of life and life-extending treatments is a good example of this.
Some especially interdisciplinary contributions in this book that exemplify this perspective include the work by Alex, which aims at integrating economic, social and ethical elements into the valuation of medical interventions, including the rights of future generations, and the work by Napiwodzka, which discusses the added value of patients’ inclusion in clinical decision-making concerning diagnosis and treatment, with a strong focus on communication and discourse.

Research on rare diseases focuses less on caregivers, who play an important role in meeting the medical and social needs of the people they care for. Caregivers of people with rare diseases face negative outcomes due to problems with diagnosis, caring for complex conditions and expensive treatments. However, the factors that affect their quality of life are poorly understood. Poor mental and physical health of caregivers has a direct impact on the person they are caring for.
To explore the literature on this topic, we conducted a scoping review in which we identified and analysed relevant studies to find out how extensively this topic has been researched. The articles were retrieved from the bibliographic databases PubMed, Ovid Medline and Ebsco Cinahl.
We initially identified 299 references and then included thirty-four articles. The included articles address three main topics, namely caregiver quality of life, health care accessibility, and the impact of health care accessibility on caregiver QOL.
This study provides information that is important to multiple providers of services as it can help to better understand caregivers and people with rare diseases and improve the quality of services offered. It highlights areas with the greatest need for change and offers insight into the complexity of caring for people with rare diseases, assisting policymakers in developing policies to support informal caregivers.
In Europe, rare or orphan diseases are defined as diseases with a prevalence of less than 5 per 10,000 people in the population [ 66 ]. The estimated number of different rare diseases is currently around 10,000 [ 32 ]. While the incidence of individual diseases is low, the collective prevalence of all types of rare diseases is high [ 76 ]. The Council of Ministers of the European Union estimates that 6 to 8% of the European population will be affected by a rare disease in their lifetime [ 58 ]. For most rare diseases, appropriate medical interventions have not yet been developed or the treatment is still unknown [ 79 ]. Although EU rare disease policy has been successful, rare disease stakeholders agree that there are still significant problems with access to orphan drugs at national level and that there are major inequalities in this area [ 61 ].
People with rare diseases and their families face the challenges of delayed diagnosis, difficult access to health care, and financially unmanageable treatment [ 74 ]. With the exception of studies focusing on specific diseases and their pathophysiology, there are few studies looking at the experiences of rare disease caregivers [ 16 ]. Caregivers of people with rare diseases are usually parents or spouses. They bear most of the physical and emotional burden of caring for a person and usually receive no financial compensation for their role [ 16 ]. In addition, many are forced give up or reduce their jobs because they have to take on the responsibility of caregiving, which can lead to additional financial problems [ 8 , 46 ].
Caregiving can involve many adjustments in a caregiver’s life, such as providing transport, running errands, providing emotional support, monitoring symptoms, taking on additional household tasks and adapting to a special diet [ 10 , 73 ]. Caregivers play an important role in the daily management of the disease. Their physical and mental state has a direct impact on the level of care they can provide to the person with the rare disease. Providing informal care can lead to unimaginable emotional, social and physical health outcomes [ 8 , 51 , 53 , 64 , 76 ].
Recently, more attention has been paid to caregivers of people with rare diseases and their quality of life (QOL). It has been shown that the role of caregivers exposes them to many negative effects resulting from the problems of diagnosis, care of complex diseases and the difficult and expensive treatment regime [ 8 , 25 , 51 ].
Studies investigating the QOL of caregivers have mostly conducted for specific rare diseases. Therefore, there is a lack of a synthesis of results that examines the factors that influence the QOL of caregivers. Knowledge about rare diseases is low, not only among the general population but also among healthcare providers [ 69 ]. Few studies have been conducted to determine how access to healthcare services affect caregivers of people with rare diseases. It has been shown, that people with rare diseases, regardless of their disease, face the same problems in accessing healthcare [ 43 ]. They encounter barriers to accessing appropriate information and specialists (who may be located in other countries) [ 76 ].
In our daily practice interacting with caregivers and people with rare diseases, we have found that there is a great need for better support and understanding of these issues and a lack of knowledge about the challenges of caring for people with rare diseases. It is therefore crucial to identify clear areas for change that should be evidence-based to help researchers, healthcare providers and other service providers develop, plan and deliver better services. To gain more information about how barriers to accessing health care affect caregivers’ QOL and to identify key areas for change. We conducted this study to learn more about how barriers to accessing healthcare affect caregivers’ QOL and to identify key areas for change. This study is one of the few to examine the relationship between QOL and barriers to access to healthcare for caregivers with rare diseases, filling a gap in international research. By exploring these questions, we aim to contribute to a broader understanding of caregiving around the world and provide valuable insights for policy makers, healthcare providers and researchers worldwide.
The aim of this study was to conduct a comprehensive literature review to address two key research questions: (1) the impact of access to health care services on the quality of life (QOL) of informal caregivers of individuals with rare diseases, and (2) the factors associated with QOL and access to health care services among informal caregivers of rare diseases.
Due to the exploratory nature of our research questions, we used a scoping review method for this study. As described by Arksey and O’Malley [ 6 ], scoping reviews serve to identify and map the available evidence on a particular topic in order to obtain a comprehensive overview of the literature. Our aim is to explore the relationship between quality of life and access to healthcare for caregivers of people living with rare diseases, and the scoping review approach fits with our aim to capture the broad landscape of literature on this topic [ 6 , 57 ]. With this review, we aim to highlight key concepts, features and knowledge gaps in the existing literature to providing a foundation for future research [ 6 , 57 ]. The methodological framework for scoping reviews proposed by Arksey and O’Malley guided us through five key steps [ 7 ].
In this study, we answered the following two research questions: (1) How does caring for a person with a rare disease affect the caregivers QOL? (2) How does access to healthcare services affect the QOL of caregivers of people with rare diseases?
For the literature search, journal articles published between 2005 and 2021 were searched using keywords in the following electronic databases: PubMed Central, PubMed, Ovid Medline, and Ebsco Cinahl. This time frame was chosen in order to capture the latest developments while ensuring comprehensive coverage of the existing literature. Literature searches were conducted in November and December 2021. We searched the database PROSPERO to ensure that no similar studies had been started or were planned. Search term strategies can be found in the additional files (refer to Additional file 3 ).
A reviewer reviewed and selected the titles and abstracts that emerged from the database searches. The full texts of the selected references were then retrieved, reviewed, and article selection followed. In addition to the search strategy, we manually searched the reference lists of the included articles. To ensure proper selection of articles, some of the full-text publications were subsequently reviewed by another independent reviewer. For access to other primary sources and full-text versions of articles, we used Google Scholar and ResearchGate. The complete list of inclusion and exclusion criteria with descriptions can be found in Additional file 4 .
A data extraction sheet was developed to record information on authors, year, country and to identify the main themes in the included articles. We recorded the information as follows: (a) Study characteristics: authors, year and country of publication, (b) study objective, (c) study design, study methods, type of QOL instruments, (d) sample size, age and sex distribution, (e) type of rare disease, (f) common themes, (g) study results. We also reported the type of sample if the study design was qualitative. Summary and evidence tables were created for this purpose. To determine whether the diseases in the included articles were rare, we checked whether the prevalence of the disease met the European definition of rare diseases, which is defined by a prevalence of less than 5 per 10 000 people in the population [ 66 ].
In the fifth and final phase of the review, information was collected on caregivers’ QOL, access to healthcare and their possible relationship. As the studies were too heterogeneous, we undertook a narrative synthesis of the results.
During the literature search, we identified 299 articles after removing duplicates. 183 articles were excluded based on title, and another 119 after reviewing the full text. The search was carried out from 22 November to 23 December. Finally, after reviewing the content of the remaining articles, 34 articles matched the searched topic. The procedure for selecting articles for a scoping review is show in Fig. 1 .
Flow diagram of inclusion and exclusion process in the scoping review
A total of 34 studies met the inclusion criteria, which are listed in Table 2: Details of selected articles found in the literature search on the QOL of rare disease caregivers; and Table 3: Details of selected articles on access to health services for rare disease caregivers (see Additional file 1 and Additional file 2 ). Twenty-four studies used quantitative methods, 6 studies used qualitative methods and four studies used a mixed methods approach. The quantitative studies primarily used questionnaires and, in some cases, online surveys ( n = 24) to collect data; the qualitative studies used face-to-face interviews ( n = 5) and focus groups ( n = 1) to collect data. The mixed methods studies used a combination of interviews (focus groups, face-to-face interviews, telephone) and questionnaires and online surveys.
The included studies were from 18 different countries. Figures 2 and 3 , showing the choropleth maps, clearly illustrate the samples included in this review. A detailed description of the included studies and the countries of origin can be found in the Additional file 5 (see Additional file 5 ).

European countries included in the review
Fifteen different questionnaires were used to analyse QOL in the studies and are listed in Table 1 The gender distribution showed a higher proportion of women compared to men in most studies. Sample sizes in the included quantitative studies varied widely, ranging from 12 to 952 caregivers and from 5 to 33 caregivers in qualitative studies.
We discovered three themes related to caregivers’ QOL. The first was the QOL of caregivers compared to other groups, such as caregivers of chronically ill or healthy control experts. The second was the dimensions of QOL that were most affected, and the third was the factors that influence the impairment of QOL.
Eight studies reported that the QOL of caregivers decreased significantly [ 1 , 5 , 28 , 37 , 49 , 54 , 67 , 82 ], seven studies also found that the QOL of caregivers was significantly lower than that of healthy controls [ 2 , 12 , 45 , 54 , 75 , 82 , 84 ]. A study by Berrocoso et al. also found that the QOL of informal caregivers of rare diseases was also lower compared to a group of caregivers of chronic diseases [ 12 ]. When comparing different types of rare diseases studies by Guarany et al. and Qi et al. found that the QOL of caregivers was significantly lower for more severe forms of rare diseases [ 31 , 65 ]. In terms of QOL and mental health, four studies reported that mothers appeared to be more affected than fathers [ 13 , 31 , 41 , 84 ]. In contrast to the previously mentioned studies, a French study found that the QOL of caregivers was consistently high, i.e. not negatively affected by caregiving [ 54 ].
In thirteen studies, caring for people with rare diseases led to lower scores in the psychological dimension of QOL, i.e. more anxiety and depression [ 5 , 12 , 24 , 28 , 36 , 40 , 45 , 49 , 52 , 54 , 70 , 82 , 84 ]. Informal caregivers often reported that the physical activity dimension was also severely impaired [ 12 , 13 , 28 , 31 , 36 , 52 , 54 , 67 , 82 ]. Four studies also reported that caregiving impacts social QOL, as caregiving burden reduces their engagement in social relationships and with their partners, which in turn negatively affects QOL [ 21 , 40 , 52 , 70 ].
The QOL of the cared-for person and the informal caregiver appears to be linked. Xu et al. found that the severity of illness perceived by patients is an important factor influencing the health-related QOL of family caregivers [ 84 ]. In addition, three studies showed that a positive relationship between the QOL of the caregiver and the QOL of the cared-for person was also a factor [ 2 , 82 , 83 ]. The age of the person being cared for appears to influence QOL of caregivers. A study by Antoniadi et al. found that relative to the patient’s age of at onset of illness, a later onset was associated with a lower QOL score for the caregiver [ 5 ]. In addition, studies by Roach et al. and Boettcher et al. found that the age of the person with a rare disease is an important determinant of QOL, with QOL increasing with age, i.e., younger age is associated with poorer QOL [ 13 , 67 ]. The duration of caregiving was also related to QOL in two studies: the longer the caregiver provided care, the lower the caregiver’s QOL [ 2 , 28 ], Kanters et al. found this was also true for the number of hours spent providing care [ 36 ]. The employment of caregivers affected QOL of caregivers. Rodríguez Bermejo et al. and Alshubaili et al. showed that all those who were unable to do paid work scored higher on measures of psychological distress [ 2 , 68 ]. Rodríguez Bermejo et al. also found that people who were separated or single had higher scores for feeling overwhelmed than the rest, and single people had lower QOL scores [ 68 ], suggesting that marital status has an impact on QOL. Caregiver sleep quality was an important factor of perceived QOL as found by Feeley et al. [ 24 ]. QOL of caregivers was also negatively affected when the person they cared for had the same residence [ 81 ]. We found two factors that positively influence the QOL of caregivers. In a Chinese study, shared caregiving was found to have a positive effect on improving caregivers’ health-related QOL [ 84 ], and three studies found that better education led to better QOL [ 2 , 12 , 84 ].
A summary of the results of the individual studies can be found in Table 3. Six studies were qualitative [ 11 , 18 , 19 , 22 , 30 , 39 ], and one was quantitative [ 33 ]. Four studies were qualitative phenomenological studies [ 11 , 18 , 22 , 30 ], two were qualitative grounded theory studies [ 19 , 39 ] and one was a cross-sectional study [ 33 ].
Five studies reported that caregivers had difficulty seeking or obtaining a diagnosis [ 11 , 18 , 19 , 33 , 39 ], and two studies reported misdiagnosis [ 11 , 39 ]. Hiremath et al. found that caregivers reported medical challenges, such as switching to multiple providers before receiving a diagnosis [ 33 ]. In addition, four studies found difficulties accessing various healthcare services (e.g., referrals to specialists, physiotherapy…) [ 11 , 22 , 30 , 39 ]. Grut et al. found that the lack of involvement of many different service providers was described by caregivers as particularly difficult when it came to healthcare providers [ 30 ]. Due to the lack of treatment options, caregivers felt they had to take whatever they could get, even if the treatment was not licenced, as reported in a study by Kesselheim et al. [ 39 ].
A common barrier to accessing healthcare services in five studies was a lack of knowledge and information on the part of healthcare providers [ 11 , 19 , 22 , 30 , 39 ]. In addition, caregivers in six studies reported difficulties in accessing information about the disease and its treatment, either on websites or from healthcare providers [ 11 , 19 , 22 , 30 , 33 , 39 ]. Currie et al. and Grut et al. found that many healthcare providers were encountering this rare disease for the first time [ 22 , 30 ]. Currie et al. and Grut et al. also found that healthcare providers sometimes made decisions based on their personal assumptions about the disease or were reluctant to refer to the information offered by caregivers and they tended not make the effort to seek additional relevant information about the diagnosis [ 22 , 30 ].
To overcome barriers to healthcare, caregivers had to adapt to the role of care coordinator, as coordination between different clinics and specialists was poor, as found in three studies [ 11 , 19 , 22 ]. Caregivers also took on the role of advocate because healthcare providers lacked knowledge and caregivers often knew more than healthcare providers, as reported in four studies [ 11 , 22 , 30 , 39 ]. Contact with other caregivers or participation in support groups proved to be a source of information for accessing healthcare services, as noted in three studies [ 11 , 19 , 39 ].
Baumbusch et al. and Hiremath et al. found that problems accessing healthcare services affect families’ financial resources as they have to pay out of pocket [ 11 , 33 ]. A study by Kesselheim et al. also found that another barrier to healthcare in certain countries is the lack of insurance coverage due to insurance companies’ lack of knowledge about the rare disease [ 39 ].
Although rare disease research is attracting increasing attention, access to healthcare services for caregivers of people with rare diseases has not been extensively studied. The aim of this review was to examine how challenges in accessing health care relate to caregivers’ QOL. To our knowledge, this study is one of the few studies to examine how QOL is viewed through the lens of barriers to accessing healthcare, with a focus on caregivers.
Our first objective was to investigate how caring for a person with a rare disease affects the caregiver’s QOL. Similar to the study by Boettcher et al. on the QOL of parents of children with rare diseases, we found that caregivers had a poorer QOL than healthy controls and caregivers of people with other chronic diseases [ 14 ]. The dimensions most affected by caregiving were psychological, physical and social. Caregivers of people with rare diseases were more likely to suffer from depression and anxiety. Our findings are consistent with a review by Pelentsov et al. which found that caregivers of people with rare diseases often feel physically exhausted suffer from sleep disturbances, fatigue, loss of appetite, weight loss, headaches and frequent colds [ 62 ]. Due to caregiving, they experience social isolation, loneliness, and dissatisfaction. Participation in social activities may be further limited by the complexity of the person’s condition and their dependence on medical devices [ 42 ]. They often feel that their social life is being cut short, that they are losing their freedom and they yearn for more spontaneity [ 62 ]. This points to the problem of the lack of respite services for rare diseases, which would allow caregivers to look after themselves and give them a much-needed break.
We found several factors that influence the QOL of caregivers of people with rare diseases. Consistent with previous research by Boettcher et al. and Pelentsov et al., we found that disease severity, patient age, education, gender, and unemployment are important factors influencing QOL [ 14 , 62 ].
In addition, we identified several new factors that influence the QOL. Sleep quality was found to correlate with QOL. As already stated by Azizi et al., better sleep quality leads to better mental and physical health and vice versa [ 9 ]. The patients perceived severity of illness was also a factor influencing caregivers’ QOL. Patients with more severe symptoms needed more support from their caregivers. It is to be expected that the QOL scores reported by caregivers caring for patients with severe illnesses would be lower than those reported by caregivers caring for patients with milder symptoms [ 20 ].
The QOL of caregivers was negatively affected if the person they cared for lived in the same house. This could mean that the person being cared for has a more severe form of the disease and needs more care, which may lead to a greater burden on the caregiver and negatively affect their QOL. These findings are consistent with those of Hughes et al. who found that having a family relationship with the care recipient and living with the care recipient were associated with higher levels of objective burden [ 34 ].
Furthermore, this could explain a positive relationship between the QOL of the caregiver and the QOL of the person being cared for. Regarding the age of the patient at the disease onset, later disease onset was associated with a lower QOL score for the caregiver. We hypothesise that this result is related to the fact that the rare disease was diagnosed later in life. This finding is similar to that of Lingen et al. who showed that the final diagnosis improves the QOL of parents whose children have a disability [ 47 ]. If this is the case, it could also be that caregivers have not received the necessary information, which is an important factor in predicting caregivers’ QOL.
The finding that a later onset of the diseases is associated with a lower QOL can also be explained by Kenny et al.‘s study, which emphasizes the significant impact on the psychological well-being of caregivers and supports the idea that early diagnosis and psychological support are crucial for better adaptation [ 38 ].
Increasing duration of care had a negative effect on QOL, both true for daily hourly care and years of care. As Vitaliano et al. emphasise, the somatic condition of caregivers deteriorates with increasing duration of care and makes them more vulnerable to the negative effects of stress [ 77 ]. Marital status was also found to have an impact on QOL. Those who were separated or were single had higher scores for feeling overwhelmed than the rest, and single people had a lower QOL, possibly suggesting that single caregivers experience less social and caregiving support and therefore experience greater strain. This could also explain the finding that shared caregiving had a positive effect on improving QOL. These interpretations would be consistent with previous findings that spouses report the lowest burden of caregiving, suggesting that sole caregiving leads to a higher perceived burden [ 34 ].
We have found that mothers have a lower QOL compared to fathers, especially in the psychosocial aspects of QOL. In families with disabled children, the traditional division of roles seems to be more pronounced, meaning that the mother takes on the role of caregiver, which is associated with lower well-being. In addition, Gray et al. have shown that illness in the family can have different meanings for men and women. In particular, women are more likely than men to blame themselves for their children’s problems and to see their identity threatened by their children’s illness [ 29 ]. As Simon noted, the differences do not just reflect differences in engagement with domestic responsibilities [ 71 ]. Even when men and women experience the same conflicts regarding work and family roles, these conflicts are interpreted differently and often to the detriment of women [ 71 ].
Our second objective was to examine how access to healthcare services affect caregivers of people with rare diseases. The most frequently cited barrier to accessing healthcare was the difficulty in obtaining a (correct) diagnosis, or the so-called diagnostic odyssey. As Nutt et al. have previously noted, delays in diagnosis and misdiagnosis are a major problem and can lead to many avoidable hospitalisations and inappropriate treatments and tests [ 58 ].
Lack of knowledge of medical staff was cited by caregivers as the most common reason for delayed diagnosis, failure of treatment or denial of social services. This led to conflicting information about the diagnosis, misunderstandings [ 78 ], or inadequate and missing information [ 26 ]. Caregivers reported how difficult it was to find healthcare providers who knew about the disease or had information about treatment. This finding is similar to that of Pelentsov et al. who found that the most frequently cited need of parents of people with rare diseases was the need for information [ 20 ]. The lack of information available to parents makes this situation difficult to deal with. Unsurprisingly, parents felt that more information and a better understanding of the disease and what to expect would help them cope with the challenges [ 17 ]. If they knew what community health services were available for their child, they could plan more confidently for the future [ 62 ]. Caregivers criticise that they refuse to seek help to overcome the limits of their knowledge [ 35 ]. The lack of knowledge and treatment options makes caregivers feel that they have to take whatever they can get, even if the treatment is not approved.
Caregivers reported limited collaboration and integration between healthcare providers, prompting them to take on the role of care coordinator to ensure that all healthcare providers have information and the newest results. They must advocate for the person they are caring for has access to much-needed services. As McMullan et al. found, caregivers often have unparalleled personal knowledge of how a rare disease affects the person, although they rarely receive enough practical or medical information to help them in their role [ 50 ]. This phenomenon often disrupts the relationship between caregivers and service providers, with caregivers taking on the role of “expert” [ 17 ]. The lack of involvement of many different service providers, but particularly the lack of involvement of healthcare providers, could be due to uncertainty about their knowledge of the rare diagnosis and therefor their suitability for treatment [ 44 ].
Problems with access to health care services also affect the financial resources of caregivers as they have to pay out of their own pocket. Although the government sometimes provides a small amount in the form of a caregiver allowance, this is not nearly enough to cover the costs of medical treatment and travelling [ 3 ]. Raising a disabled child comes with significant additional costs [ 50 ], and sometimes caregivers have to reduce their paid working hours or leave the workforce altogether [ 63 ]. Another obstacle to the utilisation of care services is the lack of insurance coverage in certain countries because insurance companies are not aware of the rare disease. A study by Gater et al. found that many drugs that are potentially effective for rare diseases are not covered by health insurance companies when used off-label in rare diseases patients [ 27 ].
We found that caregivers were able to overcome the barrier to accessing health care by interacting with other caregivers or participating in support groups, which were valuable sources of information.
Our third objective was to examine whether access to health care services affects the QOL of caregivers of people with rare diseases. Similar to our findings, Spencer-Tansley has found factors that affect the QOL, such as caregivers having to assume the role of care coordinator, social isolation, additional financial burden, and lower QOL due to time spent on care [ 72 ]. Challenges related to access to and coordination of services negatively impacted mental health. These included: trying to access health services or treatments, how care is coordinated, access to financial support, and access to other supports such as social care or respite care. Thus, we can assume that poor coordination of health services poses many emotional challenges. We found that challenges to accessing health services affect the psychological and social dimensions of QOL. Delays and difficulties in diagnosis and treatment and misdiagnosis were associated with anxiety, frustration, and stress, which affected the psychological dimension.
Even when the disease is diagnosed, finding a competent specialist can be a major problem. The psychological dimension of caregivers’ QOL is also affected, as caregivers face obstacles due to the rarity of the disease and are confronted with the lack of knowledge of healthcare providers. As von der Lippe et al. have found, the lack of knowledge about the rare disease can lead to delayed diagnosis, incorrect treatment or denial of services, all of which can have a negative impact on caregivers’ QOL [ 78 ]. Spencer-Tansley has also found that interactions with healthcare providers have a negative impact on mental health [ 72 ], and usually lead to stress, frustration and anxiety [ 17 , 63 ]. Many caregivers report that physicians are confronted with the disease for the first time and have no treatment plan for the disease, that they have no information about possible support groups, and that caregivers usually have more information than providers. Because of this, caregivers feel more responsible and have emotional reactions such as loneliness and insecurity related to the social dimension of QOL. An additional stressor for caregivers is the lack of involvement of healthcare providers. This is also a reason why they feel abandoned and frustrated, which affects both the psychological and social dimensions of QOL. The difficulty of finding a provider may be complicated by the fact that rare diseases can affect multiple organ systems. The number of specialist clinics is limited and they are located in regional centres [ 4 ] and can therefore be far away, requiring caregivers to travel long distances. This can place an additional strain on caregivers’ financial resources. Previous studies of thyroid cancer survivors also suggest that financial hardship and negative financial events are associated with poorer QOL [ 55 ].
We found that caregivers who connected with other peers online had access to information and emotional support. This is consistent with previous research on breast cancer patients that both social support from other patients can improve QOL [ 48 ].
A recurring observation in all countries analysed in this review is the predominant involvement of mothers as primary caregivers. Regardless of cultural context, mothers were the main caregivers, indicating a universal caregiving role. This finding is consistent with the comprehensive cross-cultural study by Weisner and Gallimore, who analysed data from 186 societies worldwide and found that mothers, along with female adult relatives and female children, predominantly assumed the role of primary caregiver for infants and young children [ 80 ].
Studies from Germany [ 13 ], Spain [ 12 ], Australia [ 56 ], Canada [ 49 ], Brazil [ 31 ] and Italy reported lower levels of social support, which may mean that participants from these Western countries, known as more individualistic cultures, may prioritise personal autonomy over collective caregiving tasks or may simply not have the ability to rely on family due to their schedules. This observation is consistent with the findings of Humphrey and Bliuc, who found that while individualistic traits such as personal fulfilment and freedom of expression can enhance psychological well-being, other aspects of individualism such as limited social support, competitiveness and social comparison may contribute to a decline in social relationships and mental health in Western populations in recent decades [ 37 ]. This could also explain the reliance on formal care services instead of family support mentioned in the Australian (Mori et al., 2017) and Canadian [ 22 ] studies could indicate cultural norms or societal structures that favour formalised care services over informal support networks, or simply the availability of these services that have yet to be developed in other countries.
In contrast, Nigerian caregivers reported a medium to high levels of perceived social support, indicating a more supportive social environment for caregivers in this cultural context [ 1 ]. Cultural factors such as strong family ties, community support networks or cultural norms that emphasise collective responsibility for caregiving may contribute to the higher levels of social support observed among Nigerian caregivers. In Nigeria, as in many other African countries, social support from the extended family is taken so much for granted that it is commonly referred to as the “African extended family system” [ 23 ].
This review compiled detailed information on the impact of caring for people with rare diseases on caregivers’ QOL, with a particular focus on their experiences of accessing healthcare services for the people with rare diseases they care for. It is clear that, caregivers of people with rare diseases face many unique issues and should be better supported to alleviate their burden. This study shows that healthcare systems need new strategies, as the current healthcare systems often leave it up to caregivers to become rare disease experts and advocate for to access to treatment and help. This responsibility should not be left in the hands of caregivers but, needs to be addressed systematically. By highlighting the impact of barriers to accessing healthcare services, we wanted to encourage policy makers and care providers to develop new strategies to support caregivers and improve health outcomes.
Furthermore, the consistency of our scoping review with previous studies by Boettcher et al. and Pelentsov et al. [ 14 , 62 ] emphasises the consistency of the challenges faced by caregivers in different contexts. While Pelentsov et al. focused primarily on the needs of parents of children with rare diseases, the parallels that emerge from their findings are strongly consistent with the challenges we identified in our study. This consistency highlights the universal nature of the challenges of caring for people with rare diseases and emphasises the need for comprehensive support systems tailored to the specific needs of carers around the world.
Our study has some potential limitations. First, the search strategy was limited to English-language studies. Therefore, there may be other literature that is equally relevant to the area of QOL and access to health services but may have been overlooked. Although the inclusion of articles in other languages would likely increase the selection of relevant articles, the scientific world tends to publish as much as possible in a single (English) language. The selection of articles was primarily made by one reviewer, but in cases of doubt an independent review was conducted. Also, due to the search strategy, we may have excluded many rare diseases, so QOL and access to healthcare may not be well represented for all diseases. However, this limitation was addressed by a manual search of the reference lists of included studies, which allowed us to access many studies published under other search terms.
We found that in most of the studies we examined, the voices of female caregivers were present. Less is known about the experiences and challenges faced by male caregivers. The literature often emphasises the perspective of female caregivers, so we do not understand how male carers manage their role, cope with stress and interact with healthcare systems. We do not assume that caregivers are homogeneous. Therefore, caregiving and its relationship to gender and coping must be adequately assessed to provide an accurate description of the differences between men and women in relation to this phenomenon.
The included studies that used a qualitative design utilised purposive sampling, i.e., recruitment of participants focused on sources where caregivers of children with rare diseases were active, such as hospitals and rare disease support groups. This meant that participation was limited to those who had more connections to services and peer support. Therefore, it is possible that other perspectives and experiences of services were not well represented.
On the other hand, the study also has some important strengths. As far as we know, this is one of the few studies that examines access to health services among rare disease caregivers, focuses on caregivers’ quality of life, and examines how QOL is affected through the lens of barriers to accessing healthcare. This review also includes all known research in selected bibliographic databases. The strengths of this literature review lie in its methodological and systematic approach, that explores the experiences of caregivers of people living with rare diseases from both qualitative and quantitative perspectives. The review provides insights into the complexities of caring for people with rare diseases and highlight many areas for improvement in the future to enable better planning of health care and other services.
These findings may help to understand the problems associated with caring for people with rare diseases. This information could help service providers to better understand and help caregivers of people with rare diseases to appropriate support. It can help primary care physicians by providing information about the needs of caregivers, such as the need for continuity in dealing with diagnostic uncertainty and the provision of an empowering and collaborative approach.
The review emphasises the importance of prioritising carers of people living with rare diseases in Slovenia, as they face very different challenges to carers of older people, who already receive more attention [ 15 , 60 ].
Future research should focus on examining cultural or regional differences in the impact of rare diseases on caregiver QOL and access to healthcare. Further research could focus on examining the impact of rare diseases on caregiver’s QOL with treatable diseases comapred to those without treatment. It might also be interesting to examine at how the needs of caregivers change over time. Further research should also consider the use of longitudinal studies and larger samples to investigate the impact of care on QOL. Studies such as the one by Rotar-Pavlič et al. study on the experiences and feelings of informal caregivers of elderly in Slovenia and the challenges and difficulties they face in the society [ 60 ] would also be welcome.
Caregivers’ QOL is impaired compared to parents with healthy children, parents of children with chronic diseases, and compared to normative values. Female caregivers appear to be more affected than male caregivers. We found that the physical, psychological, and social dimensions of caregivers’ QOL are most affected. Many factors seem to influence caregivers’ QOL. Caregivers of people with rare diseases have many common experiences in accessing healthcare. They struggle with lack of information, diagnosis, misdiagnosis, access to services, lack of engagement with healthcare providers and lack of treatment options. Barriers to accessing health care appear to affect caregivers’ QOL. Delays in diagnosis and lack of information can lead to increased anxiety and stress, which in turn can affect caregivers’ QOL, particularly the psychological and social dimensions. Peer support appears to be a great help in obtaining information about health services and provides emotional support. In summary, our findings reveal consistent patterns in the QOL of caregivers across different rare disease diagnoses and healthcare systems and highlight that caregivers of people with rare diseases face common challenges in different contexts.

Background: Rare diseases (RDs) affect millions of individuals collectively worldwide, contributing to significant burdens on patients and families in various aspects. However, there is a lack of evidence on the underlying patterns of burdens among diverse RDs for informing targeted social and health policies to address the unmet needs of this vulnerable population.
Objective: This study aimed to examine the underlying patterns of the health and economic burden of 33 different RDs in China and identify the potential determinants.
Methods: A nationwide internet-based cross-sectional survey was conducted in China between 2019 and 2020. Physical and mental health burden was measured by health-related quality of life. Economic burden was evaluated based on the proportions of direct medical, direct nonmedical, and indirect costs relative to household income. We used cluster analysis to identify patterns of health and economic burdens and conducted multinomial logistic regression to explore potential predictors of cluster membership.
Results: The study included 8454 adults and 8491 children affected by 33 RDs. The following 3 clusters were identified: "extremely high burden" (representing 92/8454, 1.1% and 19/8491, 0.2% of adult and pediatric patients, respectively), "overall high burden" (5933/8454, 70.2% and 4864/8491, 57.3%, respectively), and "overall low burden" (2429/8454, 28.7% and 3608/8491, 42.5%, respectively). Wilson disease, Marfan syndrome, and Langerhans cell histiocytosis more likely resulted in an "extremely high burden" than others. Poverty was significantly associated with being in this extremely high burden group. Diseases causing neuromuscular symptoms and requiring long-term treatment (eg, amyotrophic lateral sclerosis, spinocerebellar ataxia, and Dravet syndrome) were prevalent in the "overall high burden" group. Key predictors of this group included older age, lower socioeconomic status, diagnostic delay, and comorbidity.
Conclusions: This study provides novel and valuable evidence on the burden of RDs in developing regions like China. The findings reveal significant disparities in the impact of RDs, emphasizing the need for targeted health care interventions and policies.
Keywords: China; burden; economic; pattern; quality of life; rare disease.

A study published in Nature Communications provides new insight into how damaged cells interact within disease-promoting microenvironments following acute kidney injury, or AKI. With limited treatment options, AKI frequently progresses to chronic kidney disease (CKD), which affects more than 1 in 7 U.S. adults-;an estimated 37 million people.
The new findings may contribute to future efforts to prevent CKD, which can lead to kidney failure.
The study brought together scientists from Andy McMahon's lab at USC and Long Cai's lab at Caltech, with support from a USC Broad Innovation Award that funded the cross-institutional research collaboration.
In the study, co-first authors Michal Polonsky from Caltech and Louisa Gerhardt from USC, leveraged a cutting-edge tool, called seqFISH, developed in the Cai laboratory. With this tool, researchers can gather information about genetic activity and study cellular interactions in intact kidney tissue in mice with AKI. This allowed the scientists to analyze the precise expression of over 1,000 genes in the injured kidney tissue, identify microenvironments associated with injury, and predict cellular interactions associated with the progression to CKD.
" Dr. Cai's seqFISH technology provides unprecedented insight into the cellular interplay in the kidney following injury, " said McMahon, who is the W.M. Keck Provost and University Professor of Stem Cell Biology and Regenerative Medicine at USC and will join the faculty of Caltech in October. " A better understanding of kidney injury is needed to identify targets for preventing the progression to chronic kidney disease ."
Cai, who is a Professor of Biology and Biological Engineering, added: "We're thrilled that our technology has enabled a deeper understanding of kidney injury and disease. This study exemplifies the importance of cross-institutional and cross-disciplinary collaborations to advance biomedical research."
In the kidney's outermost layer, the scientists identified a likely pathological microenvironment, which they dubbed "ME-5." This microenvironment contained a type of kidney cell particularly vulnerable to injury, known as a proximal tubule cell or PT.
In ME-5, injured PTs and neighboring connective tissue cells, known as fibroblasts, exchanged signals that could drive injury progression. Key signals involved the genes Clcf1 and Crfl1, which encode proteins that can promote inflammation and fibrosis, or scarring. Additional signals detected in ME-5 could contribute to recruitment of immune cells, thereby further contributing to development of inflammation, fibrosis and other pathological changes.
The scientists also identified another important injury-associated microenvironment, which they named "ME-16," featuring aggregations of various immune cell types called tertiary lymphoid structures that are known to contribute to chronic inflammation. Rather than being confined to a specific region of the kidney, ME-16 was distributed throughout the injured organ.
To share their discoveries, the team constructed a comprehensive map of cellular, molecular, and structural changes following AKI, which refines our understanding of the transition to CKD. This map is publicly available at https://woldlab.caltech.edu/ci2-celltiles/Mouse-Kidney-Fibrosis/ .
Additional co-authors are Kari Koppitch from USC; Jina Yun, Katsuya Lex Colón, Henry Amrhein, Matt Thomson, and Barbara Wold from Caltech; and Shiwei Zheng and Guo-Cheng Yuan from the Icahn School of Medicine at Mount Sinai.
In addition to the USC Broad Innovation Award, the research was supported by the National Institutes of Health (grant NIDDK UC2DK126024), German Research Foundation (grant GE 3179/1-1), and German Society of Internal Medicine (DGIM) Clinician Scientist Grant.
