Medicare-certified hospices are required by federal regulation (42 CFR §418.64(d)) to provide bereavement counseling services to family members and others identified in the bereavement plan of care for at least one year following the death of the patient.
From Bereavement
The Wright et al. (2008) prospective cohort (n=332 advanced cancer dyads) found that patients who reported end-of-life discussions were significantly more likely to receive comfort-focused care near death and to enroll in hospice earlier (the study's primary outcomes). Among bereaved caregivers (N=202), aggressive medical care was associated with higher risk for Major Depressive Disorder (AOR 3.37; 95% CI, 1.12–10.13; P=.03) and more caregiver regret (β=0.17; P=.01). Caregiver bereavement adjustment was a secondary outcome; these are associations between care intensity and bereavement, not direct effects of EOL discussions.
From Bereavement
Prolonged Grief Disorder (PGD) was added as a new diagnostic category in DSM-5-TR (2022), establishing formal diagnostic criteria for grief that is persistent, pervasive, and functionally impairing after bereavement.
From Bereavement
Approximately 1 in 10 bereaved adults (≈10%) meets criteria for Prolonged Grief Disorder, based on a systematic review and meta-analysis of prevalence studies in general adult bereavement populations.
From Bereavement
The NCP Clinical Practice Guidelines for Quality Palliative Care (4th ed.) include grief and bereavement support as a core domain of quality palliative care, covering anticipatory grief, bereavement care planning, and follow-up for families after death.
From Bereavement
Hospice bereavement services are a federally mandated Condition of Participation, not a separately reimbursed service line under the Medicare Hospice per diem. Operators absorb the cost of bereavement programs within existing payment, making them an unfunded quality and compliance obligation.
From Bereavement
Goal-concordant end-of-life care, including documented goals-of-care conversations, is associated with measurably better family caregiver bereavement outcomes. How families fare in bereavement is one way to see whether care honored what the patient wanted.
From Bereavement
Federal regulation (42 CFR §418.56) requires Medicare-certified hospices to provide care through an interdisciplinary group (IDG) that includes at minimum a physician, nurse, social worker, and pastoral or counseling services representative, with the patient and family treated as part of the team.
From Care Team
The Service Intensity Add-on (SIA; 42 CFR §418.302) provides additional Medicare payment for registered nurse and medical social worker visits in the last 7 days of life for patients on the Routine Home Care (RHC) level of care. This creates a financial incentive to increase skilled bedside presence at end of life.
From Care Team
CMS tracks two claims-based quality measures for hospice quality reporting: the Hospice Visits in the Last Days of Life (HVLDL) measure (whether patients received a skilled visit in the last 3 days) and the Hospice Care Index (HCI), a composite of ten care quality indicators. Both are publicly reported.
From Care Team
The Home Health Value-Based Purchasing (HHVBP) Model expanded nationwide in January 2023. Home health agencies receive payment adjustments of up to ±5% based on their Total Performance Score (TPS), incentivizing quality improvement across clinical and functional outcomes for Medicare home health patients.
From Care Team
Home health Conditions of Participation (42 CFR §484.55) require a comprehensive patient assessment at the start of each care episode, including functional status, medication management, and care coordination needs. This establishes the regulatory baseline for quality home-based palliative and post-acute care.
From Care Team
The SUPPORT trial (1995; 4,804 patients at five US teaching hospitals) tested giving physicians prognostic estimates plus a trained nurse who elicited preferences and supported communication. It found no improvement in communication, DNR timing, ICU or ventilator days, pain, or resource use. The result applies to that intervention and setting.
From Care Team
A meta-analysis of 43 randomized trials found palliative care was associated with better patient quality of life (SMD 0.46) and lower symptom burden at 1-3 months, with no association with survival (HR 0.90; 95% CI 0.69 to 1.17). In the 5 low-risk-of-bias trials the quality-of-life effect was smaller (SMD 0.20) and the symptom effect was not significant. The review did not test timing of referral.
From Care Team
In a retrospective comparison of 651 patients who died (82 in a home-based palliative care program, 569 receiving usual care) in one New York ACO, program enrollment was associated with lower costs in the last 3 months of life ($20,420 vs $32,420) and fewer hospital admissions. Enrollment was not randomized.
From Care Team
Workforce projections published in 2018 indicated a growing mismatch between the supply of hospice and palliative medicine specialist physicians and projected demand. The gap is expected to widen as the aging population increases need for specialist palliative care services.
From Care Team
Staffing intensity (particularly the availability of RNs, social workers, and chaplains at the bedside near death) is a regulatory requirement (SIA, HVLDL) and a measure of whether patients and families have the people they need at the bedside in the last days of life.
From Care Team
In a single-center study of 2,031 patients with cancer who died 2018–2022, more comprehensive goals-of-care documentation was associated with less aggressive end-of-life care: 73.2% received aggressive care when none of eight GOC components were documented, versus 50.3% when seven were.
From Care Team
The most documented goals-of-care component was family involvement (75.0%); the least was fears (21.1%); only 5.4% of patients had all eight components documented.
From Care Team
In the CAPC Serious Illness Scorecard Michigan State Report, Michigan hospitals reporting palliative care by bed size: 67.4% (<50), 68.4% (50–149), 86.7% (150–299), 92.6% (300+); an estimated 92.1% of Michigan inpatients may have access to hospital-based palliative care.
From Care Team
Michigan has 286 certified palliative-care prescribers (2.9 per 100,000), no standalone Medicaid palliative benefit, and no legislatively established palliative care advisory council; it ranks 17/51 (C-TAC ACT Index) and 31/51 (AARP LTSS Scorecard).
From Care Team
A 2025 scoping review found 44 measures for goal-concordant care. No agreed criterion standard; measures vary in construct and validation.
From Care Team
An EHR-notes method for identifying goal-concordant care achieved strong inter-rater agreement (κ=0.92).
From Care Team
CANHELP is validated as a measure of patient and family satisfaction with end-of-life care, not as a measure of goal concordance.
From Care Team
In the ACP PEACE stepped-wedge cluster RCT (NCT03609177), a communication intervention increased advance-care-planning documentation by 6.8 percentage points (25.3% vs 20.8%; P<.001, primary outcome) but did not significantly change palliative care or hospice enrollment.
From Care Team
In a single-institution retrospective study (N=60 patients, Dana-Farber), GPT-4o identified advance-care-planning documentation in EHRs with sensitivity 0.85–1.0 and specificity 0.80–0.91 across ACP domains; hallucination index was low (<0.5). Limitations include small sample size and single-site design.
From Care Team
In a structured ethical stress test of 14 large language models on hospice and medical dilemmas, 7 of 14 endorsed ethically impermissible actions; 6.3% of outputs endorsed involuntary hospice transfer. Authors note these findings derive from a forced-choice stress test and do not generalize to routine clinical use.
From Care Team
A 2026 scoping review of 42 studies on AI in advance care planning found that use of generative AI is 'limited,' rule-based NLP dominates, and no randomized controlled trials of AI-delivered ACP conversations with patients have been published.
From Care Team
A 2026 scoping review of 15 studies on AI in palliative care characterized the evidence as 'geographically skewed, methodologically immature, and ethically underdeveloped'; only 2 of 15 studies measured quality of life directly.
From Care Team
Clinicians from MSK, MGH, Mayo Clinic, and Johns Hopkins published interdisciplinary practical guidance on AI for palliative care clinicians in 2026; no formal position statement from AAHPM, NHPCO, ASCO, or NCI on AI in palliative care has been identified in 2024–2026.
From Care Team
A meta-analysis of 94 interview-based studies found depression prevalence of approximately 29% across oncological, hematological, and palliative care settings. Depression is the most common psychiatric diagnosis in patients with advanced illness and is systematically under-identified and undertreated.
From Psychological Care
A meta-analysis of 38 randomized trials of palliative care interventions found no statistically significant pooled improvement in patient or caregiver anxiety, depression, or psychological distress at 3 months. Many trials (14 of 38) excluded participants with common mental health conditions. The result applies to typical palliative care interventions, not to specific psychotherapies.
From Psychological Care
In an unblinded randomized trial at one Toronto cancer center (n=305), patients with advanced cancer offered CALM plus usual care reported modestly lower depressive symptoms than usual care alone at 3 months (d=0.23) and 6 months (d=0.29), and more end-of-life preparation at 6 months. A later trial found no advantage over supportive counseling.
From Psychological Care
In a single-blind randomized trial (Mehnert et al. 2020, N=206), depressive symptoms improved over six months in both arms, but CALM was not significantly better than non-manualized supportive counselling on the primary outcome (BDI-II P=.62; PHQ-9 P=.998), and secondary outcomes were also non-significant. The active ingredients of psychological benefit in palliative settings are not yet established.
From Psychological Care
In a three-arm randomized trial (dignity therapy, client-centred care, standard palliative care; 441 randomized), distress did not differ between groups after the intervention. On a post-study survey, more dignity therapy participants reported it was helpful, improved quality of life, and increased their sense of dignity than in the other arms. These are secondary, self-reported outcomes.
From Psychological Care
In a randomized trial of 253 patients with advanced cancer (Memorial Sloan Kettering), eight-session meaning-centered group psychotherapy beat supportive group psychotherapy on spiritual well-being, quality of life, depression, hopelessness and desire for hastened death among participants who attended 3 or more sessions. In intent-to-treat analyses, only quality of life, depression and hopelessness differed significantly.
From Psychological Care
Demoralization syndrome (characterized by hopelessness, helplessness, and existential despair) is a clinically distinct condition relevant to palliative populations. It requires different assessment and intervention strategies than standard antidepressant-focused depression protocols.
From Psychological Care
A meta-analysis of HADS diagnostic accuracy in oncology and palliative settings found moderate sensitivity and specificity for identifying depression and anxiety. HADS performs best as a screening instrument rather than a diagnostic tool; abnormal scores should prompt clinical interview rather than serving as a standalone diagnosis.
From Psychological Care
The CMS CY2025 Physician Fee Schedule Final Rule (CMS-1807-F) confirms Collaborative Care Model (CoCM) and Behavioral Health Integration (BHI) billing codes under Medicare. This provides a reimbursement pathway for integrated behavioral health services in primary care and palliative settings.
From Psychological Care
The HOPE (Hospice Outcomes and Patient Evaluation) assessment tool, the CMS-mandated quality reporting instrument beginning October 2025, contains a spiritual and existential concerns item (F3000) but does NOT include the PHQ-2, PHQ-9, GAD-7, HADS, or any standardized depression or anxiety severity instrument. HOPE captures spiritual process items only; psychological severity screening remains outside the standardized HOPE measurement framework.
From Psychological Care
A meta-analysis of 25 randomized trials found antidepressants more efficacious than placebo for depression in palliative care at 4-5, 6-8 and 9-18 weeks (ORs 1.93 to 2.71). The authors say biases such as selective reporting and publication likely overestimate the effect.
From Psychological Care
Depression is common in advanced illness (about 29% prevalence in one meta-analysis). Studies of how untreated depression relates to utilization, symptom control, or quality of life are not yet cited here.
From Psychological Care
Meaning-Centered Psychotherapy for Cancer caregivers (MCP-C; NCT06307535, Mount Sinai) is an active randomized trial with planned enrollment of 200.
From Psychological Care
In a randomized trial of 240 adults with advanced cancer and depression or anxiety symptoms, an online acceptance-based group program delivered by social workers (five weekly sessions plus self-paced modules) led to 1.27 more advance care planning steps than usual care at 3.5 months (95% CI 0.36 to 2.18). Spiritual well-being, a secondary outcome, also favored the program (d=0.42). Fear of death and anxiety did not differ.
From Psychological Care
In a non-blinded wait-list pilot trial at one Singapore cardiac center, patients offered the ENABLE palliative care coaching program had a higher mean KCCQ score at 6 months than the wait-list group (difference 12.4; 95% CI 0.9 to 24.0). Caregiver quality of life did not differ. The authors plan a larger trial.
From Psychological Care
A narrative systematic review of 6 small controlled trials of multi-session music therapy in advanced cancer (438 participants; half rated high quality) found no significant change in global quality of life. Individual trials reported improvements in spiritual well-being, ego-integrity, sleep quality, and anxiety. No pooled estimate was made.
From Psychological Care
A 2026 systematic review of 8 studies of meaning in life in adult palliative cancer care (4 cross-sectional, 2 randomized trials, 1 longitudinal, 1 qualitative; 7 at high risk of bias) found meaning in life associated with less depression and anxiety and better quality of life. The authors say the evidence is too weak to recommend meaning-centered interventions for routine practice.
From Psychological Care
A published protocol (Creech et al. 2026) plans to compare 30-day readmissions after a structured chaplain intervention with a follow-up phone call against a standard spiritual support visit, in 200 hospitalized palliative care patients at one Mayo Clinic site. The paper calls the design quasi-experimental but describes randomization. No results are available.
From Psychological Care
According to the AARP/NAC 2020 national survey, approximately 53 million adults in the United States provide unpaid care to an adult or child with a disability or health condition. Family caregivers report substantial financial, physical, and emotional burden, with many reducing work hours or leaving employment entirely.
From Caregivers
The CMS GUIDE (Guiding an Improved Dementia Experience) Model, launched July 2024, provides a $2,500 annual respite benefit and care coordination support for family caregivers of Medicare beneficiaries with dementia. The 8-year demonstration model is the first CMS innovation model specifically targeting dementia caregiver support.
From Caregivers
The CMS CY2025 Physician Fee Schedule Final Rule (CMS-1807-F) established Caregiver Training Services (CTS) codes G0541, G0542, and G0543. This creates a Medicare billing pathway for training family caregivers of patients with functional impairments in care management skills, safety techniques, and disease-specific care routines.
From Caregivers
In a randomized trial of 122 caregivers of patients with advanced cancer, early telephone coaching did not change quality of life at 3 months (P=.39). Caregivers in the early group had lower depression scores (mean difference -3.4; P=.02), a secondary outcome. The comparison group received the same coaching 3 months later.
From Caregivers
In the Coping with Cancer (CwC) cohort (Wright et al., 2008; n=332 dyads), patients who reported end-of-life discussions were significantly more likely to receive comfort-focused care near death and to enroll in hospice earlier. Among bereaved caregivers (N=202), aggressive medical care was associated with higher risk for Major Depressive Disorder (AOR 3.37; 95% CI, 1.12–10.13; P=.03) and more caregiver regret (β=0.17; P=.01). Caregiver bereavement adjustment was a secondary outcome; these are associations between care intensity and bereavement, not direct effects of EOL discussions.
From Caregivers
Patients with advanced cancer who reported end-of-life conversations with their physicians had significantly lower aggregate healthcare costs in the final week of life (35.7% lower; $1,876 vs $2,917; P=.002) compared to patients who did not. Higher costs were associated with worse quality of death.
From Caregivers
The IN-PEACE RCT (Sachs GA et al., JAMA 2025) found that a dementia palliative care program for community-dwelling patient-caregiver dyads did NOT significantly reduce the primary outcome (NPI-Q neuropsychiatric symptom severity) over 24 months (between-group difference -0.24 [95% CI, -2.33 to 1.84]; P=.87). Among secondary outcomes, only one was significant: the dementia palliative care group had fewer combined ED and hospitalization events (1.06 vs 2.37 mean events/patient; RR 0.45 [95% CI, 0.31 to 0.65]).
From Caregivers
A 2021 JAMA viewpoint (Morrison, Meier, Arnold) argues that advance care planning as commonly practiced is NOT consistently associated with reduced aggressive end-of-life care in the existing evidence base. This position is contested: other evidence supports ACP benefit in specific contexts (earlier disease stage, structured facilitated conversations, longitudinal follow-up). Clinicians should be aware of this literature when counseling patients about ACP's likely effects.
From Caregivers
A nationally representative study (Yadav et al., 2017) found that approximately 36.7% of U.S. adults have completed any type of advance directive, with substantially lower completion rates among younger adults and racial/ethnic minority populations. The majority of Americans have not documented their end-of-life preferences.
From Caregivers
Caregiver burden and social support capacity are upstream determinants of hospice and palliative care outcomes: caregivers with high burden have higher rates of patient hospitalization, earlier hospice discontinuation, and lower patient quality of life at end of life. Assessing and supporting caregivers is an underused way to protect what patients and families value.
From Caregivers
The Service Intensity Add-on (SIA; 42 CFR §418.302) provides additional Medicare payment for registered nurse and medical social worker visits in the last 7 days of life for patients on the Routine Home Care level of care. This creates a regulatory and financial incentive for skilled bedside presence at the moment of dying.
From EOL Care
The Hospice Visits in the Last Days of Life (HVLDL) quality measure tracks whether a patient received at least one skilled nursing or social work visit in the final 3 days of life. It is publicly reported on Care Compare and is a direct indicator of care presence at the moment of death.
From EOL Care
Federal regulation (42 CFR §418.64(d)) requires Medicare-certified hospices to provide bereavement counseling for family members and others in the plan of care for at least one year following the patient's death. This extends the hospice's obligation beyond the moment of dying into the bereavement period.
From EOL Care
The HOPE (Hospice Outcomes and Patient Evaluation) instrument became the CMS-mandated quality-reporting tool for hospice beginning October 2025. HOPE includes a spiritual and existential concerns item (F3000) but does NOT include the PHQ-2, PHQ-9, GAD-7, or HADS. This means psychological severity is not captured in the standardized EOL quality measurement framework.
From EOL Care
The FY2026 hospice aggregate payment cap is $35,361 per beneficiary (CMS-1835-F). MedPAC's March 2026 report confirmed this figure alongside documentation of ESRD patients as a growing share of hospice with historically lower access (31.4% lower in 2024) and concurrent care barriers that limit hospice uptake for this population.
From EOL Care
The VBID Model's Hospice Benefit Component (HBC) ended December 31, 2024. The full VBID model was terminated at the end of 2025. No CMS demonstration model currently provides concurrent hospice and curative coverage at scale for fee-for-service beneficiaries.
From EOL Care
Quality signals at the end of life each look at a different part of care near death: HVLDL (last 3 days), SIA (last 7 days), HOPE F3000 (spiritual care process), and FY2026 aggregate cap performance. Together they ask whether patients had skilled visits, spiritual care and support when it mattered most.
From EOL Care
The HOPE assessment, which replaced the Hospice Item Set on October 1, 2025, includes item F3000, 'Spiritual/Existential Concerns,' asking whether the patient and/or caregiver was asked about such concerns (coded 0=No/skip, 1=Yes and discussion occurred, 2=Yes but refused) with a date field.
From EOL Care
Public reporting of HOPE-based measures will occur no earlier than November 2027 (FY 2028), with two process measures added no sooner than FY 2028, using four quarters of CY 2026 data.
From EOL Care
In the FY 2027 final rule (CMS-1851-F), CMS finalized a Medicare.gov Care Compare icon identifying hospices that fail to submit any quality data or submit less than the required 90% under the Hospice Quality Reporting Program, effective no earlier than FY 2028.
From EOL Care
For FY 2026 (final rule CMS-1835-F), CMS set a 2.6% hospice payment update (about $750M) and an aggregate cap of $35,361.44.
From EOL Care
PROPOSED: For FY 2027, CMS proposed (CMS-1851-P) a 2.4% payment update (about $785M) and an aggregate cap of $36,210.11.
From EOL Care
NICE Clinical Guideline NG31 (England) addresses recognising dying, communication and shared decision-making, maintaining hydration, and pharmacological symptom control including anticipatory prescribing. It was developed after the Liverpool Care Pathway, the prior standard approach, was withdrawn when an independent government report found its uncritical implementation could lead to poor care. Implementation barriers include the need for further clinician training and 24/7 availability of specialist support.
From EOL Care (UK module)
The Leadership Alliance for the Care of Dying People's five priorities replaced the Liverpool Care Pathway after criticism that it promoted a tick-box approach. The priorities are: recognising that someone is dying, communicating sensitively with them and their family, involving them in decisions, supporting them and their family, and creating an individualised care plan that includes adequate nutrition and hydration.
From EOL Care (UK module)
A survey of 210 respiratory physicians across England, Wales, and Northern Ireland found patients with advanced nonmalignant respiratory disease (COPD, asbestosis, diffuse parenchymal lung disease) had markedly less access to hospice in-patient and day care than patients with malignant lung disease. Only 21.5% of respondents had formal end-of-life policies for chronic respiratory disease, and 87.9% had no formal process for initiating end-of-life discussions with these patients.
From EOL Care (UK module)
A UK mixed-methods study of 147 bereavement services and 24 staff/volunteer interviews found 67.3% of services reported groups with unmet needs before the pandemic, most frequently people from minoritised ethnic communities (49%), sexual minority groups (26.5%), and deprived areas (24.5%). A quarter of services (25.2%) did not collect ethnicity data at all, limiting visibility into who isn't being reached.
From EOL Care (UK module)
A survey of 127 UK childhood bereavement services (108 responses) found 85% are located in the voluntary/charitable sector, and 44% of host organizations are hospices. This illustrates a structural difference from the US: UK hospice and bereavement provision is predominantly voluntary-sector and charity-funded, distinct from the US's primarily Medicare-funded hospice benefit (see the Service Intensity Add-on and HVLDL claims above).
From EOL Care (UK module)
A nationally representative study (Yadav et al., Health Affairs 2017) found that approximately 36.7% of U.S. adults have completed any type of advance directive, with substantially lower completion rates among younger adults and racial/ethnic minority populations. The majority of Americans have no documented end-of-life preferences at the time of a serious illness.
From Ethical & Legal
A 2021 JAMA viewpoint (Morrison, Meier, Arnold) argues that advance care planning as commonly practiced is NOT consistently associated with reduced aggressive end-of-life care in the existing evidence base. This position is contested: other research supports benefit in specific contexts (earlier disease stage, structured facilitated conversations, longitudinal follow-up). Clinicians and systems designers should weigh this evidence tension when investing in ACP programs.
From Ethical & Legal
SUPPORT found that a nurse-led communication intervention with prognostic estimates did not improve communication, DNR timing, or other targeted outcomes. It did not test information delivery alone.
From Ethical & Legal
The CMS CY2025 Physician Fee Schedule Final Rule (CMS-1807-F) established Caregiver Training Services (CTS) codes G0541, G0542, and G0543. This creates a Medicare reimbursement pathway for training family caregivers and surrogate decision-makers in care management skills, safety techniques, and disease-specific care routines.
From Ethical & Legal
The CMS GUIDE (Guiding an Improved Dementia Experience) Model, launched July 2024, provides $2,500 in annual respite and care coordination support for family caregivers and surrogate decision-makers of Medicare beneficiaries with dementia. It represents the first CMS innovation model specifically targeting informed surrogate support and caregiver burden reduction as primary goals.
From Ethical & Legal
The gap between the 36.7% advance directive completion rate (Yadav 2017) and the aspiration of goal-concordant care is the central tension: care can only follow patient preferences that are known, yet the SUPPORT trial (1995) and Morrison 2021 viewpoint show that current ACP instruments don't reliably produce them. Facilitated conversations with chaplaincy and social work support aim at this gap; information delivery alone has not closed it.
From Ethical & Legal
Cultural humility is a lifelong commitment to self-evaluation and self-critique, redressing power imbalances in the patient-clinician dynamic, and building nonpaternalistic community partnerships. Tervalon and Murray-García (1998) proposed it as a more suitable training goal than 'competence' framed as detached mastery of a finite body of knowledge about other cultures.
From Care Frameworks
A Cochrane review of cultural-competence education for health professionals (5 RCTs; 337 professionals, 8,400 patients) found positive but low-quality evidence for improved involvement in care among culturally and linguistically diverse patients, and no evidence of effect on treatment outcomes. The review concluded the evidence base is insufficient for generalisable conclusions. Training alone is not a demonstrated fix.
From Care Frameworks
In a survey of 800 elderly adults across four U.S. ethnic groups, Korean-American (47%) and Mexican-American (65%) respondents were significantly less likely than European-American (87%) and African-American (88%) respondents to believe a patient should be told a metastatic-cancer diagnosis, tending instead toward family-centered models of decision-making. The study's own recommendation: ask each patient how they want information handled and who should be involved, and never assume from group membership.
From Care Frameworks
Three dimensions of end-of-life care vary substantially across cultures: how 'bad news' is communicated, the locus of decision-making (patient-centered vs. family- or physician-based), and attitudes toward advance directives. Lower advance-directive completion in some ethnic groups is linked to health-system distrust and existing care disparities rather than indifference.
From Care Frameworks
Systematic reviews of mostly observational studies found professional interpreter use associated with better communication, utilization, clinical outcomes, and satisfaction for patients with limited English proficiency than ad hoc interpreters. A review of 10 observational perioperative studies found professional interpreter use or a language-concordant provider associated with better understanding of procedural consent.
From Care Frameworks
Kleinman's explanatory-models framework distinguishes disease (the biomedical process) from illness (the patient's culturally shaped experience of it) and treats eliciting the patient's own explanation (what they believe caused the problem, what worries them most, what they hope treatment achieves) as a practical clinical skill, not an anthropological luxury.
From Care Frameworks
The 2024 Cochrane update included 209 randomized studies (107,698 participants) across 71 healthcare decisions. Compared with usual care, patient decision aids probably increased informed values-congruent choices (RR 1.75; 95% CI 1.44–2.13; moderate-certainty evidence), and improved knowledge and accurate risk perceptions while reducing decisional conflict and passive decision-making (high-certainty evidence). Decision regret did not differ clearly between groups.
From Care Frameworks
Taken together, this evidence supports one operating rule at the bedside: elicit rather than infer. Documented group-level patterns (in disclosure preferences, decision-making style, or explanatory models) justify offering options and asking better questions. They never justify assuming an individual patient's preferences from their ethnicity, language, or faith tradition. This is the same rule ValuesInCare applies to its own tradition summaries.
From Care Frameworks
A systematic review of youth aged 10-24 pooled 25 high-quality longitudinal studies. Higher spiritual wellbeing was associated with fewer depressive symptoms (r=-0.153, 95% CI -0.187 to -0.118). Negative religious coping (feeling abandoned by or blaming God) showed a nonsignificant trend toward more depressive symptoms over time (r=0.09, 95% CI -0.009 to 0.188). Personal importance of religion was not associated with depression. Most studies were low to moderate quality, and 29 intervention studies were too varied to pool. Associations do not show cause.
From Mental Health
A meta-analysis of 10 cross-sectional studies (6,223 adult survivors of the 2023 Kahramanmaras earthquakes in Turkiye) found a small inverse association between religious coping and PTSD symptoms (pooled r=-0.21, substantial heterogeneity). Cross-sectional data cannot show whether coping lowered symptoms. The authors call this evidence suggestive. Resilience and support-seeking were analyzed separately and are not directly comparable.
From Mental Health
A JAMA Psychiatry review of 46 meta-analyses reported that religious affiliation and being married were associated with lower suicide mortality. These are observational associations; the review does not show that affiliation lowers risk.
From Mental Health
A systematic review of 6 studies in Saudi Arabia found stigma was the predominant help-seeking barrier, alongside lack of awareness, confidentiality concerns, and cultural/religious beliefs.
From Mental Health
A narrative systematic review of 46 studies in ASEAN countries listed religious and sociocultural factors under both barriers (stigma, sociocultural and religious concerns) and facilitators (social and religious support) of formal psychological help-seeking. The review does not estimate effects or test when a factor helps or hinders.
From Mental Health
A systematic review of 46 studies of Arab men in high-income Western countries found that included studies often reported attributing mental illness partly to religious reasons, favoring informal help, and citing stigma as a barrier to formal care. Findings describe those studies, not all Arab men. The authors recommend integrating men's informal support sources into treatment planning.
From Mental Health
A 2025 framework paper (COPE) proposes how mental health service organizations could partner with faith-based organizations. It reviews evidence that religion and spirituality can support wellbeing and can also be a source of trauma or a barrier to care. It gives case examples and calls for outcome research; it reports no tested outcomes.
From Mental Health
The IDF-DAR (International Diabetes Federation / Diabetes and Ramadan International Alliance) 2021 practical-guidelines update covers Type 1 diabetes fasting, elderly and pregnant patient management, and macro/microvascular risk stratification for patients who fast during Ramadan.
From Fasting & Medication
The original 2017 IDF-DAR guidelines document that exemptions from Ramadan fasting exist for serious medical conditions, but many patients fast against medical advice regardless.
From Fasting & Medication
The EPIDIAR study (12,243 patients across 13 countries) found severe hypoglycemia was significantly more frequent during Ramadan fasting in Type 1 diabetes (0.14 vs. 0.03 episodes/month, P=.0174), with fewer than half of patients adjusting their medication dose.
From Fasting & Medication
Sulfonylureas, especially glibenclamide, carry a higher hypoglycemia risk during Ramadan fasting, and insulin regimens need individualization for fasting patients.
From Fasting & Medication
In a 963-patient Saudi Arabian cohort with Type 1 diabetes, the IDF-DAR 2021 risk calculator predicted acute complications, and pre-Ramadan structured education was associated with 47% lower odds of an emergency-room visit (OR 0.53, P=.005).

A meta-analysis of 17 before/after studies (235,779 surgical patients) found three-pillar patient blood management programs were associated with fewer transfusions (RR 0.61), fewer complications (RR 0.80), and lower mortality (RR 0.89). Designs were observational, so causal effects cannot be confirmed.
From Blood Products
In a single-center cohort of cardiac surgery patients, 322 Jehovah's Witnesses managed without transfusion had 1-year survival similar to or better than propensity-matched transfused patients (95% vs 89%) and similar 20-year survival. This is an observational comparison and does not show that avoiding transfusion improves survival.
From Blood Products
A Cochrane review of 75 randomized controlled trials found intraoperative cell salvage cut allogeneic red-blood-cell exposure by 38% (RR 0.62), with no adverse impact on outcomes.
From Blood Products
A systematic review of 24 randomized and 15 nonrandomized studies found preoperative erythropoietin, with or without IV iron, may reduce transfusion rates (numbers needed to treat 3-6). Only 4 of the randomized trials were adequately powered for this outcome.
From Blood Products
A meta-analysis of 9 randomized controlled trials and 1,162 patients found preoperative IV iron lowered transfusion odds (OR 0.54, P<.001) in non-anemic patients undergoing major surgery.

A PRISMA systematic review of 56 studies found collagen is approximately 41% porcine-derived and a ubiquitous pharmaceutical excipient, affecting an estimated 1.9 billion Muslim patients. Porcine collagen is haram across mainstream Sunni jurisprudence, bovine is conditional, and fish-derived collagen is accepted.
From Dietary Law
A review of 18 palliative medications across 39 manufacturers found animal origin is not disclosed on labeling. Gelatine is 'most often but not always bovine' and manufacturers state it is 'not possible to provide definitive information,' placing the onus on the prescriber to enquire.
From Dietary Law
A survey of 100 patients and 100 physicians found more than 1,000 medications contain pork- or beef-derived gelatin or stearic acid; 84% of patients were unaware, and 63% wanted physician disclosure, while roughly 70% of physicians were themselves unaware yet thought disclosure important.
From Dietary Law
A two-hospital NHS audit found 64% of clinicians (n=50) were unaware low-molecular-weight heparins are animal-derived and 94% did not inform patients; among patients (n=137), 98% prioritized belief-aligned medication and roughly half would decline porcine prophylaxis even to prevent serious illness.
From Dietary Law
Interviews with 13 Muslim adults found Islamic necessity principles (darura/istihala) applied flexibly in practice (haram-sourced medication accepted for serious illness but avoided for minor conditions), with workarounds like opening gelatin capsules, and patients valuing disclosure, shared decision-making, and clinician religious literacy.
From Dietary Law
Standard and unfractionated heparin are porcine in origin, with fondaparinux available as a simple alternative; manufacturers often cannot differentiate the animal source of a given batch, and sources change between suppliers.
From Dietary Law
An ethics case study of a 19-year-old Muslim patient on lifesaving LDL apheresis using porcine heparin illustrates a genuine disclosure-versus-autonomy dilemma: Islamic bioethics may permit prohibited substances in lifesaving cases, but interpretations vary. This supports a cultural-humility rather than one-size-fits-all approach.
From Dietary Law
A study of 60 Muslim women who had declined porcine-derived low-molecular-weight heparin found fondaparinux (2.5mg for 10 days) resulted in zero venous thromboembolism events and no major bleeding. Fondaparinux was a safe thromboprophylaxis alternative.
From Dietary Law
A Delphi consensus of 61 bariatric surgeons across 24 countries found unanimous agreement that post-surgery fasting needs special nutritional support and surgeon/nutritionist/patient coordination; 70% recommended delaying Ramadan fasting 6-12 months after a malabsorptive procedure. This reflects a genuine tension between religious fasting and therapeutic nutrition.
From Dietary Law
A five-site survey of 98 patients found multicultural-meal access varied by site, with an African Muslim patient group least satisfied with halal provision, and only 47% of nurses accurate on religious/cultural dietary competencies. This is a descriptive finding on unmet need and satisfaction, not a controlled improvement effect.
From Dietary Law
A PRISMA review of 27 studies found gender concordance between patient and provider was generally associated with better communication and trust, especially for women discussing sensitive issues, though satisfaction findings were mixed and the provider-gender preference was more pronounced among women.
A study of 79,862 Ontario cardiac-surgery patients found physician-team sex discordance was not associated with overall mortality or length of stay, with only a small, isolated signal for isolated-CABG length of stay. This is the honest counterweight: gender concordance is not a demonstrated hard-outcome benefit.
A systematic review of 16 studies found most patients preferred a gender-concordant provider but prioritized competence over concordance when the two conflicted; concordance showed no effect on treatment adherence, mixed communication effects, and improved care quality in 2 of 3 studies measuring it.
A study of 30 Muslim immigrant women identified modesty, the assigned male physician, and cultural/language factors among documented barriers to cervical screening, with HPV self-sampling and female-clinician access identified as favorable accommodations.
A clinical review found that insufficient sensitivity to modesty is a documented barrier for U.S. Muslim women seeking cervical screening and prevention services, and recommends culturally sensitive screening strategies alongside HPV vaccination.
A survey of Nigerian gynecologists found 97.6% considered chaperones necessary and supported offering them routinely while respecting a patient's right to decline, with personnel scarcity identified as the main practical barrier.
A survey of 627 genitourinary-medicine patients in London found 88% did not want a chaperone for future exams, and those who did preferred one be offered rather than routine. Women examined by a male clinician were most likely to accept, supporting a universal-offer, patient-choice model.
A study of 149 transgender and gender-diverse patients found about half were comfortable with a chaperone, with 60.5% preferring a female chaperone; routinely offering a chaperone (especially female) was broadly acceptable, and medical mistrust, not gender dysphoria, predicted lower comfort with chaperones.
A study of 22,223 liver-transplant candidates found residence in a high-segregation neighborhood was associated with lower access to living-donor liver transplant (adjusted hazard ratio 0.81), with Hispanic/Latino candidates in high-segregation neighborhoods markedly lower still (AHR 0.59), persisting independent of insurance status.
A review of 17 studies covering 4,881 hypertensive and 40,565 normotensive living kidney donors found hypertensive donors had a significantly higher death risk (rate difference 40.0 per 1,000 person-years, P=.03), but no significant difference in kidney failure, low eGFR, or major cardiovascular events. Donor risk is real but selective, not uniform.
A survey of 589 adults in China found 36.7% would definitely accept a life-saving xenotransplant (animal-organ transplant) and 11.5% definitely would not; perceived religious conflict was significantly associated with lower acceptance (OR 0.22, P<.01).
In a survey of 916 Jewish participants in Israel, respondents' knowledge of religious rulings on xenotransplantation was associated with their attitudes across six applications; religious identity alone was not. The survey does not establish what Jewish law requires or permits.
A survey of 600 adults across Cameroon, DR Congo, and Côte d'Ivoire found 72.8% willing to accept a bone allograft; willingness was independently associated with country and religious affiliation, and religious considerations were among the leading reasons cited for refusal.
A review of 8 randomized controlled trials and 779 kidney-transplant recipients found eHealth interventions significantly increased immunosuppressant-medication adherence (RR 1.19, 95% CI 1.06-1.35, P=.01).
A broader review of 12 randomized controlled trials and 1,234 kidney-transplant recipients found eHealth adherence gains appeared only under one measurement method and were unstable on sensitivity analysis, with the overall evidence rated low to very-low quality. This is an honest counterweight to the positive eHealth-adherence finding above.
One 2022 urology reference guide (Donnenfeld and Mehta) summarizes how some religious authorities have addressed fertility treatment. It is one author team's summary and does not state what any tradition requires or permits. Ask each patient what their own faith community teaches.
A 2005 review by one author summarizes positions of some religious authorities on assisted reproduction. It does not establish what any tradition requires or permits, and positions vary within each tradition.
A study of 345 female university students in Ethiopia found 57.1% used family planning services; among non-users, 75.4% cited religious reasons as the primary reason for non-use. Religious belief was the single most-cited barrier.
In a prospective cohort of 307 women (three obstetric practices), those who attended organized religious activities a few times a month or more were less likely to score at or above the depression screening cutoff 6 weeks postpartum (OR 0.18) after adjusting for antenatal depressive symptoms and social support. Only one of six religiosity and spirituality measures was significant.
In a prospective cohort of 197 pregnant women of Mexican descent at one clinic, higher religiosity was associated with lower anxiety symptoms during pregnancy but not postpartum (b=-1.01, P=.002). Religiosity also moderated the association between acculturative stress and anxiety through 6 weeks postpartum. The authors note other groups may differ.
A narrative review of studies on pregnancy loss among Muslim women found that many women described trust in divine destiny (tawakkul, yaqeen) as easing sorrow and helping acceptance. Other themes included social isolation and stigma. The review notes limited evidence overall.
An official joint framework from the British Association of Perinatal Medicine and the Association of Paediatric Palliative Medicine recommends palliative, holistic, interdisciplinary care integrated into antenatal and neonatal care for life-limiting or life-threatening conditions. This care is explicitly not limited to babies certain to die early and supports families through diagnostic uncertainty.
A review proposes a standardized counseling framework for use at the diagnosis of a critical fetal condition, finding that communication quality directly shapes parental decision-making experience, and recommends integrating perinatal palliative care into the referral-center treatment pathway.
A longitudinal qualitative study of 16 cases, 363 parent interviews, and 108 healthcare-provider interviews found religion and spirituality directly influenced parental decision-making in 13 of 16 cases (themes: Hope & Faith, God is in Control, Miracles, Prayer). Most healthcare providers were unaware of this influence. Religion and spirituality shaped HOW decisions were made more than WHAT was decided.
A meta-synthesis of 9 qualitative studies identified parents' coping patterns, perceived value, and barriers in pediatric advance care planning, concluding that effective implementation requires respecting children's own preferences alongside parental needs.
A national guideline developed by 20 experts and 9 bereaved parents (GRADE/CERQual methodology), synthesizing 4 randomized controlled trials and 33 qualitative studies, produced 28 strong recommendations for advance care planning and shared decision-making in pediatric palliative care.
A systematic integrative review of 21 studies (4,153 citations screened) found healthcare providers often delay or avoid initiating pediatric advance care planning; prognostic uncertainty, unclear responsibility, and unpredictable parental reactions drive inconsistent practice.
A qualitative study of 18 bereaved parents and 48 PICU healthcare providers, including chaplains, identified 7 distinct professional roles in parental end-of-life decision-making: family supporter, family advocate, information giver, care coordinator, decision maker, EOL coordinator, and point person.
A peer-reviewed Catholic-perspective article argues the 'technocratic paradigm' of medicine can drive parent-provider decision-making conflicts for critically ill infants, and recommends grounding decisions in the relationality of all persons regardless of debility and in Christian hope, not in rejecting medical technology outright.
A PRISMA systematic review of 7 articles found religious leaders played both positive (trust-building, provider collaboration, community dialogue) and negative or neutral roles in COVID-19 vaccine acceptance. Their influence is not uniformly positive, though engaging them is identified as a powerful public-health strategy.
A systematic review of studies in Ghana (acceptance 17.5% to 82.6%) reported that spiritual and religious beliefs, mistrust, and safety concerns were associated with COVID-19 vaccine hesitancy. Direction of effect is not established.
A systematic review and meta-analysis of 25 studies (385,460 responders) found religion among the factors associated with European parents' HPV vaccination decisions, alongside immigrant status, employment status, and parental age.
A systematic review found a broad spectrum of vaccine beliefs within anthroposophic communities, not uniform refusal. The review also found concerns about toxicity and system trust, an emphasis on individual informed choice, and stigma directed at vaccine-hesitant members from both outside and inside the community. These findings challenge popular assumptions about values-based communities and vaccination.
In an online randomized trial of 342 Christian parents of unvaccinated adolescents, a message framing HPV vaccination with the Noah's Ark story led to higher vaccination intention than the CDC Vaccine Information Statement (beta 0.31; 95% CI 0.11 to 0.52). The trial tested one message and measured intention, not vaccination.
A systematic review of 29 studies found at least some support for a positive association between spirituality or religion and recovery from substance use disorders (abstinence, treatment retention, use severity) in most of them. The review notes limitations in the included studies and does not show cause.
In a longitudinal analysis of 262 adults (95.4% Black/African American) after residential treatment, higher spiritual well-being was associated with less frequent substance use in the first months of recovery (P=.03), and 12-step involvement with fewer consequences (P=.02). Both associations faded by 3.5 to 6.6 months. The study cannot show cause.
A systematic narrative review of 24 studies from Iran, Bangladesh, Afghanistan, Egypt, and other countries with large Muslim populations identified denial of problem severity, distrust of the treatment system, fear of confidentiality breach, and stigma as barriers to substance use treatment and harm reduction; religion was also a theme. Half of the studies met all quality criteria. The authors recommend using mosques to raise awareness and reduce stigma.
A qualitative study of 8 religious and community leaders across 5 culturally-and-linguistically-diverse community groups in Sydney documented leaders playing both barrier and enabler roles in alcohol-and-other-drug treatment access. Leaders were not solely gatekeepers of stigma.
A meta-analysis of 49 reports of community naloxone programs found that 98.3% (95% CI 97.5 to 98.8) of people survived after naloxone was given in programs serving people who use drugs, 95.0% in programs for family and community members, and 92.4% in police programs. These are survival proportions without a comparison group, so they do not measure how many deaths the programs prevent.
A Campbell systematic review and meta-analysis of 48 papers, 34 studies, and 15,255 participants experiencing homelessness found both abstinence-based (-0.28 SD) and harm-reduction (0.03 SD) interventions had confidence intervals crossing zero versus treatment-as-usual. Neither approach category showed a clear overall advantage, with individual interventions varying more than category.
A survey of 151 VA chaplains found many provide addiction care weekly with varying training and comfort levels, using foundational chaplaincy skills alongside occasional 12-step or motivational-interviewing approaches, and respondents wanted more evidence-based-modality training.
A narrative systematic review of 12 studies (mostly in Western countries; intervention-effectiveness data excluded) found positive coping strategies and coping resources, including spiritual and religious beliefs and community faith, associated with lower pre-death grief among family caregivers of people with dementia. Mostly correlational; effects of changing coping are not shown.
A survey of 493 care-dependent Austrian older adults (age 50+) found religiosity was one of the central determinants of attitudes toward euthanasia acceptance specifically, alongside living alone and fear of dying. This is reported descriptively as a correlate, not a policy position.
A qualitative study of 15 Brazilian mothers of children with severe or profound intellectual disability identified five spiritual and religious coping themes that appeared to help mothers adjust and find meaning: resilience, surrender to God's plan, predestination, child-as-blessing, and pleading for divine intervention.
A peer-reviewed Catholic Social Teaching analysis found that despite legal protections, persons with disabilities in the Philippines face ongoing structural, social, and cultural exclusion, and proposes pastoral responses grounded in human dignity, the common good, solidarity, and preferential concern for the marginalized.
A qualitative study in Zimbabwe documented African indigenous religious and spiritual framings of disability as a source of exclusion from social positions, economic empowerment, and rites of passage. However, it identified the same landscape's Ubuntu ethic of interconnection as a counter-framework offering hope for inclusion, with disability experience shaped by overlapping identities (gender, class, religion), not religion alone.
A survey of 75 individuals with serious mental illness found religious communities were among the locations most frequently named as 'welcoming' (a documented counterweight showing faith communities functioning as an inclusion resource for this population).
A population-based survey across two Philippine cities found disability combined with negative family attitudes was a documented barrier to participation in religious activities specifically, alongside work, community meetings, and social activities.
A research synthesis of 1,039 cancer-patient family caregivers across seven studies found most reported a religious affiliation; living with uncertainty was the worst-rated quality-of-life aspect, and sense of purpose or meaning was the highest-rated.
Religious and spiritual beliefs function as a heuristic some clients use to cope with genetic-risk uncertainty, and a limited spiritual assessment is recommended in genetic counseling. However, some religious/spiritual beliefs can genuinely conflict with medicine's values.
A qualitative study of 12 of 33 eligible North American genetic-counseling graduate programs found almost all cover pastoral-care information, but most offer little to no training on specific religious/spiritual beliefs or spiritual-assessment tools. Training was called critical but inconsistent and rarely evaluated.
A qualitative study of 25 practicing genetic counselors (from a national sample of 298) found religious and spiritual foundations emerged as one of five major themes in counselors' own meaning-making in clinical work.
A mixed-methods study of 200 Muslim religious officials in Türkiye found vaccine and newborn-screening hesitancy clustered around safety and institutional-trust concerns, privacy and biomaterial concerns, and fertility/genetic-harm beliefs; only 19% were aware of the OIC's pro-vaccination fatwa, and awareness was not associated with lower hesitancy.
A survey of 1,537 people across 67 countries found general support for germline gene editing, especially for medical uses, but the most opposition was found among religious respondents.
A survey of 1,004 Australians on comfort with embryo editing for research or health purposes found moral concern, a stronger driver than hereditary concern, was accentuated among more religious respondents.
A survey of 4,939 U.S. adults across 9 religious and non-religious groups found atheists most supportive and least concerned about gene editing, Muslims most concerned, and Mainline Protestants least supportive. The study explicitly cautions against generalizing attitudes within any single religious group.
A survey of 341 South Africans found 73.7% preferred a human doctor over an AI system for serious health decisions, and the importance of religion to a respondent significantly predicted this preference (P<.001).
A 2022 case-based clinical article describes meaning-centered psychotherapy and dignity therapy as structured approaches to existential distress in serious illness. It reports no new outcome data. Outcomes cited elsewhere come from separate trials, which had mixed results.
Participatory action research with a Dutch multifaith chaplaincy team documented that worldview (including secular and humanist worldview, not only organized religion) is a legitimate basis for chaplaincy professional identity in secular contexts.
A theoretical model proposes 'existential well-being' (not religious salvation or observance) as chaplaincy's goal in a secular age, an explicit first-class framework that does not presuppose religious belief.
A position article argues faith-based chaplaincy provides distinct advantages even amid declining religiosity, explicitly framed as a counterargument to the secularist-humanist perspective. It is included here as a documented counterpoint, since this topic does not resolve which model serves patients better.
A qualitative study of 5 chaplains found one in four American patients now identify as religiously unaffiliated; chaplains described spiritual caregiving as still contributing to holistic wellbeing for the spiritual-but-not-religious, secular humanist, atheist, and agnostic, and proposed an assessment tool designed for this population specifically rather than adapted from religious frameworks.
A qualitative study of 16 bereaved parents in Beijing found nonreligious parents still sought religious support facing their child's death but also needed distinctly nonreligious supports (bereavement services, death education, family support groups). This documents that nonreligious identity is not monolithic.
A scholarly commentary examines what is distinctive about a chaplain's role in working with nonreligious patients specifically, in a society where more people define themselves as not religious, arguing case studies reveal what chaplains actually do rather than relying on thin, stereotyped accounts of religion.
