Abstract
Context:
As Muslim populations in non-Muslim majority nations grow and age, they will increasingly require culturally appropriate healthcare. Delivering such care requires understanding their experiences with, as well as preferences regarding, end-of-life healthcare.
Objectives:
To examine the experiences, needs, and challenges of Muslim patients and caregivers with end-of-life, hospice, and palliative care.
Methods:
A systematic literature review using five databases (MEDLINE, Scopus, Web of Science, CINAHL, Cochrane Library) and key terms related to Islam and end-of-life healthcare. Papers were limited to English-language empirical studies of adults in non-Muslim majority nations. After removing duplicates, titles, abstracts, and articles were screened for quality and reviewed by a multidisciplinary team.
Results:
From an initial list of 1867 articles, 29 articles met all inclusion criteria. Most studies focused on end-of-life healthcare not related to palliative or hospice services and examined Muslim patient and caregiver experiences rather than their needs or challenges. Content analysis revealed three themes: (i) the role of family in caregiving as a moral duty and as surrogate communicators; (ii) gaps in knowledge among providers related to Muslim needs and gaps in patient/family knowledge about advance care planning; and (iii) the influence of Islam on Muslim physicians’ perspectives and practices.
Conclusion:
There is scant research on Muslim patients’ and caregivers’ engagement with end-of-life healthcare in non-Muslim majority nations. Existing research documents knowledge gaps impeding both Muslim patient engagement with end-of-life care and the delivery of culturally appropriate healthcare.
Keywords: Islam, community health, minority health, dying, death
Muslims are the world’s fastest-growing religious community, representing over a quarter of the world’s eight billion persons (1). While most (75%) live in Muslim-majority nations, the population in non-Muslim majority nations is large and growing. Illustratively, Muslims comprise more than 10% of the population of 10 European nations (2). Relatedly, there are 3–5 million Muslims in the United States, and the population is projected to double by 2050 (3). As with any majority immigrant community, the number of Muslim older adults is expected to rise with the natural aging of the native-born and migrant population and an increased number of elderly individuals from abroad emigrating to be near family.
As the Muslim population ages, chronic disease morbidity and mortality impact health and wellness and underscores the need for specialized healthcare services such as palliative and hospice care. In Muslim-majority countries, especially in low- and middle-income countries, there are few palliative care programs and even fewer hospice care programs (2, 4, 5). Within non-Muslim majority nations, culturally tailored end-of-life care programs are also scarce. Hence, Muslims, in general, may lack awareness about specialized end-of-life healthcare services, and the perceived cultural acceptability of such models of healthcare delivery may be low.
Notwithstanding the racial, ethnic, and sociodemographic diversity among Muslim populations, a growing body of literature demonstrates that the Muslim community’s health and healthcare-seeking behaviors are strongly, and similarly, shaped by their religious beliefs and values (6, 7). For example, Islamic beliefs inform conceptions of health, healing, illness, and cure (8, 9), and Islamic law and ethics influence choices regarding treatment options (10). Accordingly, there is ample evidence to suggest that religious beliefs and values may inform how Muslims engage with end-of-life healthcare services. Hence, studying Muslim experiences in this area of healthcare can assist in addressing unmet needs and challenges and inform the tailoring of services to their held values.
Assessing Muslim engagement with end-of-life healthcare is doubly important because of the potential healthcare inequities. In the United States, for example, Muslims appear to underutilize hospice services (11). Research further suggests that Muslim Americans lack knowledge about palliative and hospice programs (12), have concerns about religious discrimination and lack of religious accommodations within these programs (12, 13), face financial barriers in accessing specialized end-of-life healthcare (14), and may have ethical concerns with extant healthcare delivery models (5, 15). Muslims are also generally under-represented in end-of-life healthcare research (16).
Hence this systematic literature review appraises the state of the healthcare research literature on the question, “What are the experiences, needs, and challenges of Muslim patients and caregivers within non-Muslim majority nations with regard to end-of-life, hospice, and palliative care?” While scholars have conducted systematic literature reviews assessing end-of-life healthcare through the lens of religion (17–19), on studies conducted in one country (e.g., Iran (20); United Kingdom (21)), and on end-of-life care issues faced by Muslim patients in Muslim-majority countries (22, 23), there has been no systematic review, to our knowledge, addressing the aforementioned focus question.
Methods
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to organize this systematic review (24). Studies were included if they were empirical (either quantitative or qualitative), conducted in high-income, non-Muslim majority nations, focused on adults (18 years or older), and published in English. The list of high-income, non-Muslim majority countries was derived from the World Bank’s list of high-income countries (25) and information from the Pew Research Center regarding the percentage of population by religion (1) [see Appendix A for a list of countries eligible for inclusion in this review]. This review was not registered.
Five bibliographic databases containing health research studies were searched (Ovid MEDLINE, Scopus, Web of Science, CINAHL, and Cochrane Library) in March 2022. MeSH headers and exploded terms were used to uncover pertinent articles. The general search string covered two areas: (1) Islam or Muslims, and (2) terms related to end-of-life, hospice, or palliative care [See Appendix B for greater details]. In this review, “end-of-life” refers to end-of-life care without specific reference to specialized hospice or palliative care services.
Duplicates were removed from this initial list of retrieved papers before title and abstract review, which was conducted by four members of the research team. Two members reviewed each record for relevance to the research question independently. After removing studies that did not meet inclusion criteria or were irrelevant, full-text review of each article was performed by two team members independently. For both title and abstract review, as well as full-text review, any discrepancies on whether a paper met inclusion criteria or was relevant were resolved by team consensus. Rayyan software was used to facilitate the review (26).
The team used the Qualsyst rubric for quality assessment (27). Each article was rated independently by two team members; if there was a large discrepancy in the scores given to an article by the original two reviewers, two further team members rated the article. The scores for each article were averaged; only high-quality studies (i.e., those with an average score of 0.75 or higher (23)) were included in the final review.
Data abstraction from the final slate of included papers was performed by two members of the research team. They gathered information on the location of study, research design (quantitative or qualitative), population studied, the age range of participants, sample size, percentage of males/females, end-of-life healthcare topic studied (end-of-life, hospice, palliative), as well as the healthcare domain that the findings spoke to (28). We used domains from the National Coalition for Hospice and Palliative Care practice guidelines. These categories refer to the (1) structure and processes of care, (2) physical aspects of care, (3) psychological and psychiatric aspects of care, (4) social aspects of care, (5) spiritual, religious, and existential aspects of care, (6) cultural aspects of care, (7) care of the patient nearing the end of life, and (8) ethical and legal aspects of care. Additional notes about the paper’s findings and how Islam/religion was discussed within the paper were also captured in the data collection spreadsheets and informed qualitative thematic content analysis (described below).
To synthesize the studies quantitatively, the articles were categorized in four different ways. First, the articles were categorized by whether patients or caregivers were studied. Caregivers included family as well as healthcare professionals (HCPs) such as physicians, chaplains, nurses, and social workers. Second, the articles were categorized by whether they principally examined healthcare experiences, needs, or challenges (see Table 1 for definitions). Third, they were categorized according to whether the research examined general end-of-life healthcare (i.e., not including hospice or palliative care services), hospice care, or palliative care. Fourth, the articles were categorized by healthcare domain from the NCP guidelines. Importantly, a study could belong to multiple categories within each division (e.g., it could describe experiences and needs with regard to hospice and palliative care and cover providers and patients).
Table 1:
Definitions of experiences, needs, challenges, and other.
| Category | Definition |
|---|---|
|
| |
| Experiences | The accounts of individuals and groups in healthcare settings, including the involvement and participation with the healthcare system from both patient and healthcare provider perspectives. |
| Needs | The wants and requirements for healthcare practices and healthcare resources disclosed by study participants; they could be from the patient or the healthcare provider perspective. |
| Challenges | Specific barriers that participants faced regarding end-of-life healthcare; for example, a patient might find it difficult to access end-of-life healthcare, a health care provider may be unsure how to meet patient needs, or both parties might face challenges with communication and understanding. |
| Other | Attitudes and beliefs of individuals and groups outside of the healthcare setting; these attitudes included the opinions that society—outside of current patients and healthcare providers—has about end-of-life healthcare |
The research team developed qualitative findings by analyzing repeated themes contained within the results, findings, and discussion sections of the studies (29) in a team-based manner. Each article was read independently by two team members, and these reviewers noted how the findings related to the core research question. These main ideas (codes) were discussed at team meetings as each reviewer summarized the articles along with their main ideas by referencing the papers’ results and discussion sections. The presentations were followed by team discussions to derive generalizable themes across the set of articles by grouping these ideas into higher-order salient themes. Team-based consensus building was used to resolve any differences in article ideas and themes.
Results
A total of 1867 articles were identified by the database searches, of which 1004 were unique articles. Based on the inclusion/exclusion criteria, 933 articles were excluded, and 71 full-text articles were retained for review. After reviewing these articles for pertinence to our study question, a further 30 were excluded. An additional 11 articles were retrieved from a hand search of the bibliography of related systematic reviews (17, 18, 21, 30–32), leading to a total of 52 articles in our review. Of these, 29 were assessed to be of high quality, and our findings build up from these articles [See Figure 1 for flowchart and Table 2 for the final articles; quality ratings are in Appendix C].

The 29 articles were published between 2004 and 2022, and 17 were quantitative studies while 13 were qualitative investigations. The studies were conducted in six countries: United States (n = 14), United Kingdom (n = 6), Belgium (n = 3), the Netherlands (n = 3), Singapore (n = 3), and Canada (n = 1). One study took place in 17 unspecified European countries (33).
Quantitative Results
Among the 29 articles, 17 articles studied patients, and 16 articles studied caregivers. Among the articles that studied patients, most focused on general end-of-life healthcare excluding palliative and hospice services (n = 14), followed by palliative care (n = 4) and hospice care (n = 2). In this group of patient-focused studies, experiences (n = 5) and challenges (n = 5) were more studied than needs (n = 3). Among the articles that studied caregivers, the focus of most articles was similarly on general end-of-life healthcare (n = 13), followed by palliative care (n = 5) and hospice care (n = 1). Again, caregiver experiences (n = 13) were more studied than needs (n = 2) or challenges (n = 1).
Concerning the domain of healthcare, the greatest number of articles were categorized under the domain of care of patients nearing the end of life (n = 10), spiritual, religious, and existential aspects of care (n = 8), and ethical and legal aspects of care (n = 8). The least studied domains were physical aspects of care (n = 2) and psychological and psychiatric aspects of care (n = 0). More information about the above categorizations of the articles included in this systematic review can be seen in Appendices D–F.
Qualitative Results
Three main themes, with several subthemes, emerged from reviewing individual study findings. These themes are presented below through recourse to data contained within the individual studies [see Table 3 for a list of themes and subthemes].
Table 3:
Themes and subthemes
| Themes | Subthemes |
|---|---|
|
| |
| The family’s role | Familial caregiving as a moral duty The family as surrogate communicators and protectors of hope |
| Lack of knowledge | Lack of provider knowledge and comfort surrounding religious dimensions of end-of-life healthcare Lack of patient and family knowledge on the role of palliative care and/or advance care planning Lack of educational resources to facilitate Muslim engagement with palliative care |
| Muslim physician perspectives and practices | The influence of provider religiosity on healthcare delivery Variability among Muslim physician practices in end-of-life healthcare |
The Family’s Role
The first theme revolves around the role of family in end-of-life healthcare with two subthemes: (i) familial caregiving as a moral duty, and (ii) the family as surrogate communicators and conveyors of hope.
Familial Caregiving as a Moral Duty.
Caregiving of relatives at the end of life was often voiced as a familial obligation (12, 34–36). The term “family” was not restricted to one’s nuclear family; rather it could cover one’s neighbors or local religious community (12, 34). Indeed, in a qualitative study of various racial/ethnic groups in Michigan, Arab Muslim participants expressed that one should be cared for by one’s family when close to death (12).
High-quality care was envisaged to have family involvement, as voiced by a participant in a study of Muslim cancer patients of Turkish or Moroccan background living in the Netherlands: “Good care implies that you can call on your family. Your family is obliged to care for their sick relative properly…The rule is – a devoted family cares for the ‘seriously ill’ patient” (34).
Furthermore, the vision for a ‘good death’ included one’s family providing support to the patient at home. As one participant in a study of older South Asians in East London states, “A true Muslim should die at Mecca, or Medina, and facing east. The Day of Judgment comes there. If it is not possible, then he should die at home with his family around him” (Amir, Pakistani male, age 58 years) (36).
Dying at home was generally preferred, as Arab Muslim participants in the aforementioned study done in Michigan indicated that they would prefer to be at home with their families at the end of life (12). Muslims’ desire to die at home was also reflected in a study of 300 cancer patients in Singapore, where 89.9% of Muslim respondents wanted to die at home compared to 70.7% of respondents overall (37). With the inability of most immigrant populations studied to return to “their homeland”, being at home in the presence of family was viewed as conveying respect for the dying person’s comfort (36). As authors of a qualitative study on the perspectives of South Asians living in the United Kingdom, which included Muslims and members of other religious groups, surrounding end-of-life healthcare in the home note:
Views of home as a place where religious needs at the point of death could be met contrasted sharply with most participants’ perceptions of what death might be like in the hospital. There was a belief that dying in hospital would restrict the family in their ability to perform caring and religious tasks and in providing comfort (36).
As part of the familial obligation to care, there was an expectation that one’s family would be aware of their responsibilities when the time came to care for their loved one, but also that financial considerations could waive this obligation. As noted by the authors of a study on end-of-life healthcare perspectives of older South Asians living in East London, which included Muslims and members of other religious groups:
Many believed that their family would “know what to do” and would do what they could for them when it was their time to face death and dying. Moreover, it was clearly indicated by some that pre-planning is unnecessary, since any decisions will depend on “family circumstances” (35).
The Family as Surrogate Communicators and Protectors of Hope.
In addition to serving as caretakers, patients’ families serve as surrogate communicators to healthcare teams and sustainers of a patient’s hope. Studies noted that one’s interactions with family and friends during serious and/or life-limiting illness impact one’s notions of hope (34, 38). Three studies reported that, for Muslims, talking about death and dying can contribute to the patient “giving up” and thus hastening one’s death (34, 38, 39). Accordingly, and given their religious belief in God’s control over disease and cure, there appears to be a reluctance to disclose prognosis or discuss terminal state as a factual certainty. As noted in a study of cancer patients in the Netherlands of Turkish or Moroccan background: “Some respondents also say that they cannot take away the patient’s hope for religious reasons. According to them, it is for Allah to decide when someone is going to die; life and the possibility of recovery are in Allah’s hands” (34). Furthermore, “relatives and friends encourage(d) participants to keep an optimistic attitude and expressed their belief in future improvement in their foundation either through medical care or a divine miracle” (38). Aside from giving hope to the patient, the skirting of matter-of-fact prognostication served to protect the family from anxiety and stress (35). Studies reported that Muslim patients worried about being a burden on relatives, both emotionally and practically (35, 38–41).
In a qualitative study of South Asian patients with life-limiting illnesses in Scotland, the lack of discussions about death and dying among Muslim participants was said to be a barrier to accessing hospice and palliative care (39). The control of information from family to patient, especially in the context of language barriers and families serving as interpreters also creates tension for health professionals (39). As the wife of a South Asian Muslim patient shared, “I said to them ‘don’t tell him how long [he has to live]’ but they said if he asks any questions, they’ll have to tell him. He never asked” (Carer 20, wife of Muslim patient with cancer, Stage 1 interview) (39).
Lack of Knowledge
The second theme relates to a lack of knowledge of both the religious and biomedical contexts on the part of many stakeholders. Specific subthemes were (i) a lack of provider knowledge and comfort surrounding religious dimensions of end-of-life healthcare, (ii) a lack of patient and family knowledge on the role of palliative care and/or advance care planning, and (iii) a lack of educational resources to facilitate Muslim engagement with palliative care.
Lack of Provider Knowledge and Comfort Surrounding Religious Dimensions of End-of-life Healthcare.
Barriers to advance care planning (ACP) and goals of care discussions with Muslim patients and families were attributed to preconceived notions of patients’ preferences and/or a lack of understanding of Islamic cultural/religious practices. In a study of 74 interdisciplinary healthcare workers, clinicians appear to avoid ACP discussions with certain religious beliefs, highlighting Muslims, assuming patients would be reluctant to participate (42); clinicians also voiced a lack of awareness of teachings and traditions around ACP and end-of-life healthcare among Muslims. Illustratively, a study assessing healthcare workers’ knowledge of teachings around end-of-life healthcare of the three major monotheistic religions (Christianity, Judaism, Islam) reported that providers had the least perceived understanding of Islamic traditions, regardless of provider specialty or seniority (43).
Further exploring the impact of limited cultural knowledge, healthcare workers interviewed as part of a study of South Asian Sikh and Muslim patients in Scotland and their caregivers described a fear of making a “cultural blunder” as a contributing factor to the avoidance of providing palliative care (39):
Most healthcare and social care professionals expressed good intentions in striving to provide equitable care but were concerned by their lack of cultural understanding and were uncertain about how to adapt their usual care. “Not knowing much about the religion . . . that is sometimes difficult because you don’t really know what you are talking about . . . maybe if I had known more about that then I could have been more help to him” (Patient 20, interview with professional after death) (39).
Lack of Patient and Family Knowledge on the Role of Palliative Care and/or Advance Care Planning.
For Muslim patients and families, there appear to be significant knowledge gaps surrounding palliative care and ACP. In a study of 148 Muslim adults living in the United States, about half (46.6%) of participants had not heard about ACP (44). This was associated with low rates of engagement in ACP, evidenced by a lack of ACP documents and formal ACP conversations (44). In another study using the same dataset, awareness and knowledge of ACP predicted engagement in ACP, as did immigration status and level of acculturation, suggesting that increased years of residency in non-Muslim majority nations may afford more opportunity for ACP engagement and foster understanding (45).
Lack of Educational Resources to Facilitate Muslim Engagement with Palliative Care.
The apparent lack of knowledge could be related to a lack of educational resources, as noted in a national survey consisting of 62 hospice social workers. In this study, almost all identified the importance of religion and spirituality amongst their patients, and more than half (68%) requested more education about the religious and spiritual needs of their patients, especially Muslims (46). Other professionals recognized a lack of training in diversity and cultural awareness as a problem, or that existing training was ineffective (39, 46). One study piloted an educational intervention consisting of a 60-minute video podcast as a resource. That intervention significantly increased provider understanding of Christian, Jewish, and Islamic teachings around end-of-life healthcare (43).
Muslim Physician Perspectives and Practices.
The third theme focused on Muslim physician experiences in end-of-life healthcare delivery. Two subthemes emerged: (i) the influence of provider religiosity on healthcare delivery and (ii) variability among Muslim physician practices in end-of-life healthcare.
The Influence of Provider Religiosity on Healthcare Delivery.
Physician religion and spirituality impacted views surrounding the provision of spiritual care at the end of life (33, 47, 48). In a study of Muslim physicians in the United States, higher physician religiosity was associated with lower odds of addressing non-Muslim patients’ religious or spiritual needs (47). In that study, more than half of participants believed it was never or rarely appropriate to encourage non-Muslim patients at end-of-life to seek forgiveness of those they have wronged or to seek reconciliation with God, which may signal further discomfort in engaging in religiously laden end-of-life care conversations with patients with a different religious background (47).
Another analysis of the same dataset revealed that more religious physicians struggled ethically and psychologically with withdrawing life-sustaining therapy in competent adults (48). A study of the palliative care attitudes and practices of Muslim doctors in the Netherlands echoed these findings; Muslim physicians were more likely to oppose withholding or withdrawing artificial nutrition or hydration (ANH) when compared to non-evangelical Protestant or Catholic physicians (49).
In a qualitative study of 15 Muslim physicians, also in the Netherlands, palliative care was described as “serving the ultimate goal in medicine: avoiding suffering” (50). In another study of 10 Muslim physicians in the Netherlands, palliative sedation was noted as alleviating suffering and a professional duty. Indeed, even though Islamic law views palliative sedation as a prohibited act, some Muslim physicians participated in this practice as they viewed alleviating suffering as a professional obligation: “As far as I am concerned, as a physician I am there to put the patient first and also to protect them, and in this pain relief is a must” (Khadidja) (51).
In both studies, however, interviewees spoke of the potential conflict that palliative care (and palliative sedation) could have with the Islamic perspectives on suffering, especially as a means of expiation of sins (50, 51). Muslim physicians struggled to reconcile these views. As one participant shared:
“Some views within Islam say: well suffering is a kind of penance, a means by which you expiate your sins. But this is contrary to the steps you would normally take as a doctor [to alleviate suffering/pain]…” (quote 19, participant 6, line 167–170) (51).
Variability Among Muslim Physician Practices in End-of-Life Healthcare.
Overall, the opinions of Muslim physicians surrounding the end of life were not uniform. A study of 461 Muslim physicians practicing in both Muslim-majority and non-Muslim majority countries surveyed perspectives about Islamic views surrounding resuscitation. Notably, physicians graduating from or practicing in non-Muslim majority countries were more likely to agree that do not resuscitate (DNR) was acceptable in Islam compared to their counterparts in Muslim-majority nations (52).
This variability was further exemplified when looking at Muslim physician views surrounding death by neurologic criteria (DNC). The results of a study of 255 Muslim American physicians highlight differing perspectives. While the majority (90%) agreed that cardiac death was considered death, participants were divided on whether ‘brain death’ and cardiac death were equivalent states (54% in agreement) (53). In contrast, a survey of 92 Muslim American health professionals found that 84% of respondents believed that if a person is determined to be dead by neurologic criteria, they are considered dead; yet half of respondents felt family should have choice in whether evaluation for DNC is performed and whether organ support is discontinued after DNC (54).
When compared to other physician groups, other differences may appear. For example, a study of end-of-life healthcare decisions of 3086 patients over 18 months in various European intensive care units found that end-of-life healthcare varied depending on the physician’s religious affiliation; life-sustaining therapy was withheld more often than withdrawn if the physician was Muslim (63%, total n=24), Jewish or Greek Orthodox (33).
Discussion
Our systematic literature review sought to identify the experiences, needs, and challenges of Muslim patients and caregivers within non-Muslim majority nations with regard to end-of-life, hospice, and palliative care. While we obtained some insights from the extant studies, the research literature, by and large, is too scant to provide substantive details; 29 empirical studies cannot ground definitive conclusions about Muslim experiences, needs, and challenges related to end-of-life healthcare. As such, the principal finding from our review is that greater research is needed.
Nonetheless, our research reveals several important themes about Muslim engagement with end-of-life healthcare and describes specific gaps in the literature. Principally, studies highlight profound knowledge gaps among Muslim patients and family members about the importance of advance care planning as well as decisional points of import and religious and ethical dimensions of such decisions. Simultaneously, end-of-life healthcare providers struggle with a lack of understanding of Muslim cultural or religious mores and have few resources to fill in this knowledge. Knowledge and research gaps, in our view, may contribute to the lack of access and utilization of palliative and hospice care among Muslim populations, and to a poor quality of care delivered for those who do obtain such services. The scant research literature likely exacerbates this gap as few investigators appear to be focusing on investigating Muslim patient and caregiver experiences, needs, and challenges. Thus, knowledge cannot be generated and the goal of improving healthcare quality at the end of life is frustrated.
Accordingly, there is an urgent need to build research platforms to fill in such educational and resource gaps. Academic healthcare systems should partner with Muslim communities to conduct community-engaged research that maps out specific knowledge gaps and community concerns, and subsequently design and test interventions to address them. It is noteworthy that only a handful of studies examined Muslim experiences and needs related to palliative and hospice care. Without detailed research into Muslim values, needs, and perspectives on palliative and hospice care, the ability to tailor these services is out of reach. Moreover, the lack of research may exacerbate underutilization and healthcare inequities. Hence, we call on healthcare research funders, both local and national, to support descriptive research focused on assessing Muslim Americans’ understanding of, values related to, and need for palliative and hospice care. Lastly, given the importance of religion in the healthcare decision-making of Muslims, and the ethical challenges that appear to arise in end-of-life healthcare, it would be prudent for researchers and educators to partner with Islamic authorities in such efforts.
There are several limitations to this study. We limited our review to published articles, so expert opinion, conference proceedings, and other commentary pieces were not included. Though studies in all high-income, non-Muslim majority countries were included, due to the paucity of published studies in this population, a relatively small number of countries were represented: the United States, the United Kingdom, the Netherlands, Canada, Belgium, and Singapore. The exclusion of non-English publications may have contributed to this limited capture. Furthermore, our development of themes rested on the results sections of the papers reviewed and not the participant data itself; as such, our findings may not fully reflect participant experiences. Finally, it is critical not to overgeneralize our findings because the literature is quite limited, and Muslims are quite diverse. While we hazard that the shared religious identity of Muslims, as well the common features of healthcare systems in mid- to high-income countries, allow for aggregating the experiences, needs, and challenges of the Muslims living in non-Muslim majority nations together, other aspects of identity (e.g., ethnicity) and other contextual circumstances (e.g., immigrant status) may more significantly shape end-of-life healthcare experiences, needs, and challenges of participants in the studies we reviewed. Again, further research may be able to disentangle these various intersectional factors and provide more actionable data on how to better attend to the shared values among Muslim communities whilst also honoring the individual unique qualities inherent to anyone who calls themselves a Muslim. Despite our study’s limitations, our work, nonetheless, provides the foundation for future directed and targeted studies that begin to fill in knowledge around Muslim engagement with end-of-life healthcare in non-Muslim majority nations.
Key message:
Few studies examine the experiences, needs, and challenges of Muslim patients and caregivers in non-Muslim majority nations with end-of-life, hospice, and palliative care. Yet, studies highlight the importance of family involvement in end-of-life care and significant knowledge gaps for patients and providers that impede quality care delivery.
