Patient–Caregiver Dyads in Severe and Advanced COPD: Relationships, Caregiving Burden, and Intervention Support: A Narrative Review

Abstract

Background

Informal caregivers are central to the home management of severe and advanced chronic obstructive pulmonary disease (COPD), particularly when patients have high symptom burden, recurrent exacerbations, respiratory disability, long-term oxygen therapy (LTOT), or home non-invasive ventilation (NIV). This narrative review synthesizes evidence on patient–caregiver relationships, caregiving burden, and intervention support in these high-need COPD phenotypes.

Methods

We conducted an iterative narrative review using PubMed as the primary database, citation chaining from included literature, and targeted searches of guideline and organizational sources through March 2026. The synthesis drew on 96 publications spanning quantitative and qualitative studies, systematic and narrative reviews, randomized trials and trial protocols, clinical practice guidelines, and policy reports. Evidence was charted by design, population/phenotype, measures or intervention, main findings and key limitations.

Results

Four dimensions emerged from the evidence: (1) multidimensional caregiver burden; (2) changing patient–caregiver relationship dynamics; (3) evolving caregiver roles across the severe-COPD trajectory, including LTOT, home NIV, exacerbations, hospitalization, and palliative care; and (4) intervention and support-system responses. Caregivers report anxiety, depression, fatigue, social restriction, financial strain, and uncertainty, while patient–caregiver disagreement about symptoms and support can intensify distress. Evidence is strongest for guidelines and systematic reviews confirming high need and for selected rehabilitation and breathlessness interventions; it is weaker for caregiver-specific, long-term, technology-supported, and low-resource interventions. The Zarit Burden Interview is widely used but has limited content validity in COPD caregiving; COPD-specific or caregiver-validated measures such as Informal Caregiver Burden Assessment Questionnaire (QASCI) and the Carer Support Needs Assessment Tool warrant greater use.

Conclusion

For people with severe or advanced COPD who depend on regular home support, care should more consistently recognize the patient–caregiver dyad as an important unit of assessment and intervention. Routine caregiver needs assessment, education for advanced home therapies, family-inclusive rehabilitation, psychological support, and needs-based palliative care are promising components of care.

Introduction

Chronic obstructive pulmonary disease (COPD) remains a major cause of symptoms, disability, hospitalization, and premature mortality worldwide.^1,2 Its consequences are not limited to airflow obstruction: as disease progresses, breathlessness, exacerbations, deconditioning, multimorbidity, and treatment complexity reshape everyday life for patients and for the family members or friends who support them.^3–5 The patient–caregiver dyad provides a useful framework for understanding these reciprocal effects because caregiver involvement can influence treatment adherence, escalation of care, emotional adjustment, and use of home-based therapies, while caregiving can simultaneously affect the caregiver’s own health and quality of life.^6–9

This narrows the focus to people with severe, advanced, or respiratory-handicapped COPD who are most likely to need sustained physical or psychological support at home. The need for dyadic care is not uniform across COPD: patients with mild or stable disease may self-manage with little informal assistance, whereas severe or advanced disease can make everyday activities, treatment administration, and crisis recognition dependent on another person.^4,10,11 High-support phenotypes include: (1) disabling breathlessness and functional dependence; (2) GOLD Group E or frequent exacerbations; (3) severe resting hypoxemia requiring LTOT; (4) chronic hypercapnia treated with home NIV/BiPAP; (5) coexisting OSA treated with CPAP; (6) advanced multimorbidity; (7) frailty; and (8) transition toward palliative or end-of-life care.^2,12–17

GOLD 2026 lowers the threshold for Group E to at least one moderate or severe exacerbation in the previous year, emphasizing that a single event can identify higher future risk.^2,12 For dyads, this classification has practical implications: action plans, early recognition of deterioration, medication access, transport decisions, and post-exacerbation rehabilitation all become shared tasks.^9,18,19 The revised classification should not be interpreted as meaning that every Group E patient requires intensive caregiving; rather, it identifies a population in which caregiver involvement and support needs should be assessed. For these patients, family caregivers may help with mobility, medications, oxygen or ventilation equipment, exacerbation monitoring, transport, communication with clinicians, and emotional containment.^4,9,10,20

LTOT illustrates the dual nature of advanced treatment. ATS guidance strongly recommends LTOT for COPD with severe chronic resting hypoxemia and recommends education for patients and caregivers on oxygen equipment and safety.¹³ Oxygen can enable survival and activity, but it also introduces equipment management, tubing hazards, electricity and supply costs, travel restrictions, fire-safety concerns, stigma, and dependence on reliable suppliers.^4,21,22 Qualitative work with severe COPD caregivers and professionals shows that hospital and community services often underestimate the practical knowledge caregivers need to sustain home treatment.²³

Home NIV adds another layer of complexity. ERS and ATS guidelines conditionally support long-term NIV for selected patients with chronic stable hypercapnic COPD and recommend targeting carbon dioxide reduction.^14,15 In practice, caregivers may help with mask fitting, skin checks, cleaning, troubleshooting alarms, monitoring adherence, transporting equipment, and coordinating follow-up. These tasks can be especially burdensome at night, when caregivers may monitor breathing or respond to equipment problems. CPAP is not a treatment for COPD itself, but it becomes relevant when OSA coexists; the ATS NIV guideline recommends OSA screening before long-term NIV initiation.¹⁵ Advanced home respiratory technology should therefore trigger structured caregiver education, a written emergency plan, and periodic reassessment of caregiver capacity.

The pathway integrates risk recognition, medical and advanced home-treatment management, caregiver assessment, psychosocial and palliative support, and feedback after exacerbations (Figure 1).

Figure 1.

Multicomponent care pathway for severe and advanced COPD patient–caregiver dyads.

As disease severity, exacerbation burden, multimorbidity, frailty, and home-treatment complexity increase, physical care demands and psychological needs tend to reinforce one another (Figure 2).

Figure 2.

Conceptual interaction between COPD severity and physical/psychological care needs.

The caregiving literature has grown substantially, but it remains uneven. Systematic and scoping reviews document substantial burden and unmet needs, while also showing that many studies are descriptive, cross-sectional, small, or focused on mixed COPD severity rather than the highest-need phenotypes.^24–26 Evidence for interventions is promising but heterogeneous: pulmonary rehabilitation, caregiver education, breathlessness services, palliative care, and digital support differ in content, intensity, target population, and measured caregiver outcomes.^25,27–30

This review aims to synthesize what is known, and what remains uncertain, about severe and advanced COPD patient–caregiver dyads, with particular attention to long-term home care, advanced respiratory therapies, multimorbidity and frailty, socioeconomic burden, measurement, and support systems.

Methods

This is a narrative review. PubMed was the primary literature source, supplemented by backward and forward citation chaining from included literatures and by targeted searches of guideline and organizational sources. The updated search covered literature available through March 2026. Search terms combined COPD with caregiver, carer, spouse, family, dyad, caregiving burden, support needs, severe or advanced disease, exacerbation, long-term oxygen therapy, home oxygen, non-invasive ventilation, BiPAP, CPAP, pulmonary rehabilitation, palliative care, frailty, multimorbidity, socioeconomic burden, telehealth, and low- and middle-income countries.

Publications were considered relevant if they addressed adults with COPD and one or more of the following: informal caregiver or dyad experiences; caregiver burden, needs, health, or quality of life; severe, advanced, exacerbation-prone, oxygen-dependent, ventilator-dependent, disabled, frail, or multimorbid COPD; caregiver-inclusive interventions; palliative or end-of-life care; caregiver-relevant measurement instruments; or health-system and policy responses. Guidelines and major policy documents were included when they directly informed severe COPD home care, caregiver support, LTOT, home NIV, pulmonary rehabilitation, or palliative care. Publications were excluded when they focused only on professional caregivers, pediatric populations, asthma without COPD, or lacked caregiver-relevant information.

For each eligible publication, we charted design, population/phenotype, measures or intervention, main finding and key limitation. The evidence was then synthesized thematically. Four dimensions, multidimensional burden, relationship dynamics, evolving caregiver roles across the severe-COPD trajectory, and intervention/support systems, emerged during this iterative synthesis. The final synthesis drew on 96 publications. Table 1 summarizes representative empirical studies, reviews, guidelines, and trial protocols to make the underlying methods and limitations visible.

Evidence strength was interpreted by design and convergence across sources. Clinical practice guidelines, Cochrane reviews, systematic reviews/meta-analyses, and randomized trials were given greater weight than single cross-sectional or qualitative studies. Qualitative studies were used to describe mechanisms, lived experience, and implementation barriers. Divergent findings and limitations are reported alongside the main synthesis.

The evidence base is broad but asymmetric. Caregiver burden and unmet needs have been documented in systematic reviews: Mansfield et al identified 27 quantitative papers, most of which were descriptive, with only one measurement study, one intervention study, and two longitudinal studies.²⁴ A later systematic review of caregiver interventions found 20 studies, but only nine reported caregiver-related outcomes and most interventions were not designed specifically for caregivers.²⁵ A 2025 scoping review similarly concluded that caregivers report inadequate information, emotional strain, physical burden, and uneven access to support across settings.²⁶ Qualitative syntheses provide rich descriptions of how caregivers maintain stability, recognize exacerbations, organize care, and advocate for patients.^3,9

The strongest intervention evidence comes from randomized or controlled evaluations of family-inclusive pulmonary rehabilitation and integrated breathlessness services, although these studies remain few and often include mixed advanced respiratory populations.^27,28 Guidelines offer consistent recommendations for palliative care, home oxygen, and home NIV, but many recommendations are conditional and based on moderate to very low certainty evidence.^13–15,39 Caregiver-specific psychological, digital, socioeconomic, and palliative interventions remain under-tested, especially in low- and middle-income countries.^26,29,40,41 These limitations temper the conclusions that can be drawn.

Multidimensional Burden in Severe and Advanced COPD

Psychological, Physical, and Social Morbidity

Caregivers of people with advanced COPD report anxiety, depression, sleep disturbance, fatigue, and sustained vigilance.^4,42–44 Cross-cultural studies in Europe, Asia, and North America show that caregiver psychological morbidity can approach or exceed that reported by patients, particularly when breathlessness is severe, exacerbations are frequent, or the caregiver is older, female, socially isolated, or providing many hours of care.^31,44–47 In one prospective study of caregivers of hospitalized patients, patient dependency after discharge predicted caregiver depression, and caregivers providing more than 20 hours of weekly care were at particular risk.³¹ These findings are clinically plausible but largely observational; they identify risk markers rather than prove causation.

Breathlessness is a central driver of dyadic distress. Patients describe fear, loss of control, and a shrinking social world, while caregivers report helplessness when they cannot relieve episodes of breathlessness.^48–50 Patient-perspective work, including social-media listening, also places cough, mucus, and shortness of breath among the most salient concerns, reinforcing the need to assess symptoms rather than lung function alone.⁵¹ Caregivers may remain in a state of alertness, monitoring breathing, sleep, oxygen saturation, equipment, and early signs of exacerbation.^10,20 Qualitative studies describe this as being “never at ease,” particularly when professional support is fragmented or inaccessible.^23,52

Social isolation and compassion fatigue are common consequences of sustained care. Caregivers reduce work, leisure, friendships, and community participation as the patient’s world becomes more homebound.^3,53,54 A 2025 study of elderly COPD patients linked social isolation and caregiver compassion fatigue with poorer patient emotional and functional outcomes, reinforcing the reciprocal nature of dyadic distress.⁵⁴ Caregivers also report their own chronic conditions, impaired health status, and lower quality of life, including in population comparisons with non-caregivers.^55–57

Roles, Intimacy, Identity, and Relationship Disruption

Severe COPD changes the meaning of partnership. Aasbø et al described the struggle to maintain a shared biographical we while accommodating disability, uncertainty, and care responsibilities.⁵³ Spouses may move from partner to nurse, coordinator, technician, and advocate, often without formal recognition or training.^10,53,58 This transition can produce ambivalence: caregivers want to protect and remain involved, yet may feel resentment, guilt, grief, or loss of their former identity.^10,20,59

Intimacy and sexuality are also affected. A systematic review and meta-analysis found high prevalence of sexual dysfunction in COPD, including substantially higher erectile dysfunction than in age-matched controls, while qualitative evidence indicates that breathlessness, fatigue, anxiety, body-image changes, and equipment use can interfere with physical and emotional closeness.⁶⁰ Evidence for effective sexual-health interventions in COPD remains sparse.⁶¹ These concerns are rarely discussed in routine care, despite their relevance to dyadic quality of life.

Long-Term, Financial, and Socioeconomic Burden

Severe COPD caregiving is often measured in years rather than weeks. Population and cohort studies show that caregivers of people with end-stage lung disease may provide care for prolonged periods and report unmet needs for information, symptom control, physical care, and emotional support.^62,63 Economic analyses estimate that informal care for disabled people with COPD represents billions of euros in annual societal value, even though this work is largely unpaid and invisible in health budgets.⁶⁴ The same study linked higher dependency to greater informal-care time and cost.

Financial strain arises from direct costs—medications, oxygen electricity and supplies, transport, home adaptations, and private care—and indirect costs such as reduced working hours, early retirement, lost pension contributions, and depletion of savings.^19,62,64 Socioeconomic disadvantage can intensify every stage of the pathway: patients may have greater exposure to smoking or biomass fuels, delayed diagnosis, poorer access to rehabilitation and home technology, and fewer resources to purchase respite or private support.^2,26,65 Female and older spousal caregivers may be especially vulnerable because they combine longer care hours with their own morbidity and lower financial reserves.^19,44,47

Multimorbidity, Frailty, and Complex Treatment Burden

Severe COPD rarely occurs in isolation. Heart failure, diabetes, OSA, asthma–COPD overlap, osteoporosis, anxiety, depression, and other long-term conditions complicate symptoms, medications, appointments, and self-management.^2,5,12,66 Heart failure can mimic or amplify breathlessness; diabetes may require intensive monitoring and diet or insulin management; OSA can require CPAP and complicate NIV decisions; asthma–COPD overlap can alter inhaled therapy; and psychological distress can reduce motivation, adherence, and rehabilitation participation.^2,15,67,68 For caregivers, multimorbidity means coordinating several regimens and interpreting overlapping symptoms rather than managing a single respiratory diagnosis.

Frailty is highly relevant to dyadic care. A systematic review of 53 studies found wide prevalence estimates (2.6–80.9%) depending on the frailty measure, setting, and age, with frailty associated with mortality, exacerbations, hospitalization, dyspnea, COPD severity, poorer quality of life, and disability.¹⁷ A second meta-analysis of 20 studies and 11,620 participants estimated frailty prevalence at 32.07% and found lower FEV₁, shorter six-minute walk distance, poorer activities of daily living, higher symptom scores, and increased long-term mortality among people with frailty.⁶⁹ Frailty therefore identifies patients who may need more intensive caregiver support, rehabilitation adaptation, falls prevention, nutrition assessment, medication review, and advance care planning.

Multimorbidity and frailty also affect intervention design. A Cochrane mixed-methods review found that interventions for COPD plus other long-term conditions often require tailoring to competing symptoms, polypharmacy, functional limitations, and patient priorities rather than simple addition of disease-specific programs.⁶⁶ Dyadic assessment should therefore include not only FEV₁ and exacerbation history but also cognition, mobility, nutrition, mood, caregiver health, home environment, and capacity to manage oxygen, NIV, CPAP, nebulizers, and multiple medications.

Burden at the End of Life and After Critical Care

The palliative phase of COPD is difficult to identify because decline is gradual and punctuated by potentially reversible exacerbations.^3,16,70 Nevertheless, worsening breathlessness, functional decline, repeated admissions, increasing dependence, weight loss, psychological withdrawal, and caregiver-observed deterioration can signal transition toward palliative care.^16,39 End-stage lung disease caregivers report substantial unmet needs, including information about the future, symptom control, service availability, and emotional support.^62,71

Hospitalization and ICU care can leave persistent psychological sequelae for both patients and caregivers. In a multicenter study, caregivers of COPD ICU survivors reported high levels of anxiety at ICU discharge, with clinically important symptoms persisting at day 90; post-traumatic stress symptoms were also common.⁷² Qualitative studies describe moral distress when caregivers witness uncontrolled breathlessness or question life-sustaining treatment in critical care.⁷³ These experiences support early communication about prognosis, treatment preferences, and likely burdens of escalation, while recognizing that prognostic uncertainty remains substantial.

Measuring Caregiver Burden and Support Needs

Measurement is a major weakness in the COPD caregiving literature. The Zarit Burden Interview (ZBI) is widely used, but it was not developed specifically for COPD. Selzler et al conducted cognitive debriefing with Canadian and Portuguese caregivers of people with moderate to very severe COPD and found that, although the instrument was generally understood, many items were not relevant: in Canada, 3 of 22 items were not understood and 8 were irrelevant to at least one-third of participants; in Portugal, 1 item was not understood and 20 were irrelevant to at least one-third.³⁴ The authors concluded that the ZBI, in its current form, does not adequately represent COPD caregiver experience.

The Informal Caregiver Burden Assessment Questionnaire (QASCI) has emerging COPD-specific evidence. In 50 caregivers, QASCI correlated strongly with ZBI (r=0.908), HADS anxiety and depression, and WHOQOL-Bref domains, with internal consistency of 0.793 and an intraclass correlation coefficient of 0.924.³⁵ These findings are promising but come from a small single-country validation study, so further cross-cultural validation is needed.

Burden scores should be complemented by needs assessment. The Carer Support Needs Assessment Tool (CSNAT) assesses domains of support that caregivers may need for themselves and to enable them to care. A systematic literature search found substantial overlap between CSNAT domains and established COPD carer needs, but also identified COPD-specific concerns such as understanding breathlessness and knowing what to expect.⁷⁴ A subsequent focus-group study found that COPD carers considered all 15 CSNAT domains relevant and the facilitated assessment acceptable.³⁶ Routine assessment should therefore combine a burden measure, a needs tool, psychological screening, and practical questions about advanced home treatments and emergency planning.

Dyadic Dynamics: Navigating Severe COPD Together

Congruence and Discordance in Symptom Perception

Patients and caregivers do not always perceive symptoms and needs in the same way. In advanced COPD, agreement between patients and carers is only fair to moderate at the individual level and is weakest for subjective symptoms such as breathlessness, anxiety, and depression.³² Proxy reports may overestimate patient distress, particularly when caregivers are anxious, depressed, not co-resident, or not spouses.^32,75 These discrepancies matter when clinicians rely on proxy reports, when caregivers decide to seek urgent care, or when patients minimize symptoms to avoid hospitalization.

Discordance also affects behavior. Patients and partners may disagree about activity restrictions, medication use, smoking, oxygen or NIV adherence, and whether symptoms warrant emergency care.^18,33 During exacerbations, caregivers often play a decisive role in recognizing deterioration and initiating care-seeking, but conflict can arise when patients want to remain at home or avoid clinicians.^9,18 Shared action plans should therefore specify observable triggers, preferred first contacts, oxygen/NIV instructions, and hospital preferences while preserving patient autonomy.

Overprotection, Protective Buffering, and Conflict

Supportive intentions can become unsupportive when they undermine autonomy. Overprotection—doing too much for the patient or restricting activity—can reduce self-efficacy and increase dependence, while protective buffering—hiding worries to avoid upsetting the patient—can reduce open communication.³³ In a dyadic study, discrepancies in perceptions of overprotection were associated with patient distress, suggesting that the meaning and visibility of behavior matter as much as the behavior itself.³³

Conflict is not inherently harmful; it may signal unclear roles, fear, or mismatched expectations. Qualitative studies show that caregivers want clearer guidance about when to encourage activity, when to rest, when to use rescue medication, and when to call for help.^10,20,23 Dyadic interventions should make communication about these decisions explicit rather than assuming that caregiver involvement is always beneficial.

Support, Positive Appraisal, and Dyadic Coping

Caregiving also includes meaning, closeness, mastery, and reciprocal commitment. Studies of advanced chronic organ failure found that caregivers can report relatively positive caregiving appraisals and family well-being despite objective strain.⁷⁶ Positive appraisal does not eliminate burden, but it can coexist with fatigue and grief.^63,77 Social support and adaptive coping appear to buffer the effect of burden on caregiver quality of life, although most evidence is cross-sectional.⁷⁸

Dyadic coping, the ways couples communicate, share problem-solving, and maintain a sense of we, is associated with quality of life and psychological distress in COPD.^8,58 Open communication, shared decision-making, and balanced support may help couples preserve autonomy and relationship quality. However, evidence is limited by small samples, self-report measures, and few longitudinal studies; dyadic coping should therefore be viewed as a promising intervention target rather than an established causal mechanism.

Evolving Caregiver Roles Across the Severe-COPD Trajectory

Diagnosis, Stable Severe Disease, and Exacerbations

The caregiver role often develops gradually as patients lose function and treatment becomes more complex. Many family members do not initially identify as caregivers even when they provide substantial assistance.^3,4 During stable severe disease, caregivers support medication routines, physical activity, nutrition, appointments, oxygen or ventilation equipment, and emotional regulation.^4,9,22

Exacerbations are turning points. Caregivers must distinguish usual breathlessness from deterioration, initiate action plans, arrange urgent care, communicate history, and manage post-discharge dependence.^18,20,31 They may disagree with patients about symptom severity or the need for hospital care, which can delay or complicate escalation.¹⁸ After discharge, caregivers face medication changes, rehabilitation referrals, oxygen/NIV reassessment, and uncertainty about prognosis.^20,79 Transitional interventions that include caregivers and provide clear contact pathways are therefore relevant, although evidence in COPD-specific dyads remains limited.^79,80

Advanced Home Treatment: Oxygen, NIV, CPAP, and Nebulized Therapy

Advanced home treatment changes the caregiver role from emotional supporter to co-manager of medical technology. Oxygen requires safe storage, flow checks, tubing management, battery or cylinder planning, fire-safety precautions, and travel arrangements.^13,21 NIV and CPAP require mask and interface care, cleaning, adherence monitoring, troubleshooting, and coordination with respiratory or sleep services.^14,15 Nebulized therapy adds time, cleaning, medication sequencing, and infection-control tasks, and caregivers may perceive both benefit and burden.²²

These therapies should prompt structured caregiver training rather than informal handover. At minimum, teams should assess who will manage the equipment when the patient is breathless, fatigued, cognitively impaired, or hospitalized; provide written troubleshooting and emergency instructions; review electricity, backup supply, and travel plans; and reassess caregiver burden after initiation.^13,15,23 Current guidelines specify patient selection and technical management but provide limited evidence on how best to support the caregiver workforce that makes home treatment feasible.

Palliative Care, Advance Care Planning, and End-of-Life Support

Palliative care in COPD is a holistic, multidisciplinary, person-centered approach to controlling symptoms, improving quality of life, and supporting informal caregivers.³⁹ ERS guidance recommends considering palliative care when physical, psychological, social, or existential needs are identified through holistic assessment; offering interventions in accordance with needs; providing advance care planning according to preferences; and integrating palliative care into routine COPD care.³⁹ The 2022 ATS policy statement similarly advocates earlier integration across serious respiratory illness, and recent narrative syntheses translate COPD-specific palliative-care hallmarks for palliative and respiratory clinicians.^81–83

Advance care planning remains underused. Barriers include uncertain prognosis, fear of removing hope, misconceptions that palliative care means abandonment, lack of clinician confidence, and limited time.^70,84,85 Patients and caregivers often need practical information about expected trajectories, breathlessness management, oxygen/NIV decisions, hospitalization, resuscitation, preferred place of care, and whom to contact in a crisis.^62,71,85 Web-based tools may support communication, but they should complement rather than replace clinician-led conversations.⁸⁵

The evidence does not justify presenting early palliative care as a single solution. A systematic review found mixed and often underpowered evidence for palliative interventions in COPD, although acceptability was generally high and caregivers valued education, breathlessness support, and having someone to contact.²⁹ The randomized breathlessness support service trial showed improved mastery and a survival signal in advanced disease, but it included mixed diagnoses and cannot establish that all early palliative models produce the same result.²⁸ Home palliative-care services may improve outcomes for advanced illness and caregivers in broader populations, but COPD-specific effects and optimal timing remain uncertain.⁸⁶ A needs-based, flexible model is therefore more defensible than automatic referral at a fixed disease stage.

Interventions and Support Systems for the Dyad

Palliative Care Integration and the PalliPulm Framework

Palliative care integration can be conceptualized at three levels: primary palliative care delivered by respiratory and primary-care clinicians, specialist palliative care for complex needs, and system-level integration across home, community, hospital, and hospice services.^39,81,84 The ERS guideline supports needs-based palliative care and caregiver support, while the ATS policy statement encourages proactive integration earlier in serious respiratory illness.^39,81

The 2026 ATS PalliPulm workshop report adds an educational and practice framework for pulmonary-critical care medicine.³⁸ It prioritizes symptom management, serious-illness communication, and caregiver support in ambulatory settings, and serious-illness communication, symptom management, palliative-care fundamentals, and end-of-life care in inpatient settings. PalliPulm is important because it shifts some palliative tasks from scarce specialist services to trained respiratory teams, with specialist referral reserved for complex symptoms, communication, or end-of-life needs. Its effectiveness as an implementation model still requires prospective evaluation.³⁸

Pulmonary Rehabilitation, Family-Based Programs, and Caregiver Education

Pulmonary rehabilitation is a core intervention for symptomatic COPD, and family-inclusive models can address the relational context in which exercise, breathlessness management, nutrition, and self-management occur.^27,30,87 In a randomized trial, adding family-based psychosocial support and education to pulmonary rehabilitation improved family coping more than conventional rehabilitation.²⁷ A home-based program integrating caregivers reported short-term improvements in caregiver burden, anxiety, depression, and fatigue, but lacked a caregiver control group.³⁰ Qualitative evidence suggests that next of kin value being informed and included rather than treated as incidental observers.⁸⁷

Caregiver education can reduce burden and improve quality of life when it is structured around COPD management, symptom recognition, medication and equipment use, exacerbation plans, communication, and self-care.^88,89 However, the evidence base is small, interventions vary widely, and follow-up is often short. Education should be adapted for LTOT, NIV/CPAP, nebulizers, frailty, and multimorbidity rather than limited to generic disease information.

Psychological and Dyadic Interventions

Psychological distress is common in patients and caregivers but is under-recognized and undertreated.^67,68,90 Barriers include overlapping physical and psychological symptoms, stigma, fragmented mental-health referral, and care models that do not address dyadic mechanisms.⁶⁸ Cognitive-behavioral and rehabilitation-based approaches may improve short-term symptoms, but durable effects and caregiver-specific benefits are uncertain.^25,90

SERENE is a major ongoing trial that directly addresses this gap. It will enroll 375 COPD patient–support-person dyads with elevated depressive symptoms and randomize them 2:1 to 12 weeks of family-partnered Coping Skills Training or COPD education delivered by phone or videoconference.³⁷ The primary efficacy outcome is patient PHQ-9 score at 14 weeks, and mechanistic outcomes include family relationship quality, patient and caregiver self-efficacy, loneliness, and caregiver psychological distress.

Digital Health and Remote Dyadic Support

Telehealth, remote monitoring, online support groups, and e-mental health may improve access for homebound patients and caregivers, especially in rural areas or when mobility is restricted.^91–93 Cochrane evidence suggests telehealthcare may improve quality of life and reduce emergency visits or hospitalizations in COPD, but effects and optimal models remain uncertain.⁹¹ The COVID-19 pandemic accelerated remote care while also revealing risks of isolation, unequal digital access, and loss of relational continuity.⁹³

Innovative dyadic models include guided online group singing for people with COPD or interstitial lung disease and their carers (SINFONIA), which aims to address breathlessness, quality of life, and social isolation.⁹⁴ A systematic review of e-mental health interventions for informal caregivers found that flexibility and convenience facilitate use, while time constraints, technology problems, privacy concerns, and poor fit with caregiver needs impede implementation.⁴⁰ Digital care should therefore be offered as an option within blended care, with attention to digital literacy, language, disability, connectivity, and caregiver preference.

Community, Health-System, and Emerging-Country Support

Support for severe COPD dyads depends on more than individual interventions. Coordinated primary care, respiratory nursing, home care, rehabilitation, social care, respite, palliative care, oxygen and ventilation suppliers, and mental-health services all influence whether home management is sustainable.^4,23,95 In rural and underserved areas, telemedicine and outreach may mitigate distance, but they cannot substitute for equipment supply, emergency care, home nursing, or financial protection.⁹²

The gap is especially important in low- and middle-income and emerging countries. WHO estimates that 56.8 million people need palliative care each year, most in low- and middle-income countries, and only 40% of countries in a 2019 survey reported that services reached at least half of those in need.⁴¹ WHO’s Integrated Care for Older People (ICOPE) framework offers a community-level model for identifying declines in intrinsic capacity, developing person-centered care plans, coordinating referral, and supporting caregivers.⁹⁶ For severe COPD, an ICOPE-informed approach could link primary-care screening for breathlessness, frailty, mood, nutrition, mobility, and caregiver strain with community rehabilitation, home oxygen/NIV support, social protection, and palliative care.

Emerging health systems need context-appropriate models rather than direct transplantation of high-resource specialist services. Priorities include affordable oxygen and electricity supply, trained community nurses, caregiver education in local languages, remote consultation where appropriate, essential medicines for breathlessness and pain, social-work and financial counseling, and integration of informal caregivers into discharge planning.^26,41,96 Research should test implementation and equity outcomes, not only efficacy.

Discussion

Principal Findings

This narrative review indicates that severe and advanced COPD creates a reciprocal care situation in which patient symptoms, functional dependence, treatment complexity, and psychological distress interact with caregiver capacity, health, and relationship quality. The four emergent dimensions—burden, dyadic dynamics, evolving roles, and intervention/support systems—provide a practical structure for assessment. The burden is greatest when disease is severe or unstable, home technology is required, multimorbidity or frailty is present, socioeconomic resources are limited, and palliative needs are emerging.^{4,16,17,62,64}

The review also cautions against assuming that every patient has or wants a caregiver, or that more caregiver involvement is always better. Some patients live alone, lack family support, or prefer formal services; some caregivers are overprotective, distressed, or themselves frail; and some supportive behaviors can unintentionally reduce autonomy.^26,33 The dyad should therefore be treated as an important unit of assessment when present and relevant, not as an inseparable or universal structure.

Strengths and Limitations of the Evidence

Several evidence domains are relatively robust. Systematic reviews consistently show caregiver burden, unmet needs, and gaps in intervention research.^24–26 Guidelines converge on home oxygen for severe resting hypoxemia, selected use of home NIV in chronic hypercapnia, needs-based palliative care, and caregiver education.^13–15,39 Randomized evidence supports selected family-inclusive rehabilitation and integrated breathlessness approaches, but not all models or outcomes.^27,28

Important limitations remain. First, many caregiver studies are cross-sectional, small, and based on convenience samples. Second, disease severity and phenotype are inconsistently reported, making it difficult to isolate LTOT, home NIV, GOLD E, frailty, and palliative subgroups. Third, caregiver outcomes vary across studies, and the most widely used burden instrument has content-validity limitations in COPD.³⁴ Fourth, interventions often include caregivers only when available and rarely test caregiver-only, long-term, culturally adapted, or low-resource models.²⁵ Fifth, publication and language bias cannot be excluded because this was not a systematic review.

Implications for Practice

For severe or advanced COPD, clinicians should routinely ask who helps the patient, what tasks that person performs, whether they can manage oxygen/NIV/CPAP and medications, and what support they need.^13,15,36 Assessment should include caregiver health, anxiety and depression, sleep, social support, financial strain, and understanding of emergency plans. The CSNAT can structure needs assessment, while QASCI may be considered where validated; ZBI results should be interpreted cautiously because some items may not fit COPD caregiving.^34–36

Care plans should be dyadic but autonomy-preserving. They should include inhaler and medication review, action plans, rehabilitation, nutrition and frailty assessment, comorbidity management, advanced-treatment training, psychological support, social and financial referral, and needs-based palliative care.^2,39,66 After exacerbations or initiation of LTOT/NIV, caregiver education and follow-up should be scheduled rather than assumed. In resource-limited settings, community health workers, telehealth, and ICOPE-informed integrated care may provide pragmatic routes to support.^40,96

Future Research

Research should move beyond describing burden toward testing mechanisms and scalable interventions. Priorities include: longitudinal studies of dyads across GOLD E, LTOT, home NIV, frailty, and palliative trajectories; standardized and COPD-valid caregiver measures; trials of caregiver-specific and dyadic psychological interventions; evaluation of caregiver training for advanced home technology; economic evaluations that include unpaid care; and studies in low- and middle-income countries and underserved populations.^26,34,37,38 Trials should report caregiver outcomes, intervention fidelity, equity, harms, and durability, and should include patients without available caregivers as a distinct group.

Conclusion

Severe and advanced COPD can create substantial, sustained demands for patients and the informal caregivers who support them, particularly when recurrent exacerbations, respiratory disability, LTOT, home NIV, multimorbidity, frailty, or palliative needs are present. The evidence supports more routine recognition of caregiver burden and support needs, better education for advanced home treatments, family-inclusive rehabilitation and psychological care, and needs-based integration of palliative care. It also supports caution: the dyad is not universal, caregiver involvement is not automatically beneficial, and no single intervention has been shown to solve the problem across settings. A pragmatic model is to assess the patient and caregiver together when a caregiver is present, tailor support to phenotype and needs, preserve patient autonomy, and build health-system capacity for equitable home, community, and palliative support.
