Frameworks Aim to Make Participation Matter for People Living With Multiple Long-Term Conditions
As multiple long-term conditions become more common, the question is no longer whether people with lived experience should be involved in health research. The sharper issue is how to involve them in a way that changes the design, delivery, and relevance of care. A BMJ Public Health scoping review mapped the theories, frameworks, and models used to guide engagement of people living with multiple long-term conditions, or PLwMLTC, and found that structured approaches can do more than invite participation on paper. They can shape education, behavior change, peer support, and coordinated care in ways that are visible at the bedside.
The review searched PubMed, Scopus, CINAHL, and Embase on 20 December 2024, without date restrictions, and used Arksey and O’Malley along with Levac and colleagues’ methodological frameworks. From 756 screened articles, 25 met inclusion criteria. The range is important because it shows how scattered the literature remains, even as the clinical burden of multimorbidity grows across non-communicable diseases. Engagement is not a soft add-on here; it is part of whether an intervention can work in real patients with layered disease, competing priorities, and fragmented care.
Twenty-Five Models, but One Common Aim: Better Fit Between Care and Lived Experience
The frameworks most often used were the Chronic Care Model, Collaborative Care Model, Health Belief Model, Transtheoretical Model, Patient-Centred Medical Home, Improving Mood-Promoting Access to Care Model, and Patient-Centred Care Model. Each carries a different emphasis, yet all attempt to reduce the distance between health systems and the people they serve. Some focus on population-level organization, others on individual readiness to change, and others on team-based care or psychological access to treatment.
A few frameworks leaned heavily on patient education and behavior change, while others were built around community-based care or peer support. In practical terms, those strategies are more than engagement rhetoric. A patient who understands the rationale for treatment, sees the plan reflected in daily life, and receives support from peers is more likely to sustain the kind of long-term behavior change that chronic disease management requires. In multimorbidity, where one diagnosis can complicate another, this alignment becomes especially valuable.
The review also linked several frameworks to clinical gains, including improvements in blood pressure and depression. Other models appeared to influence sociobehavioral outcomes rather than hard clinical endpoints. That split matters because it reflects the reality of multimorbidity research: a framework may first improve self-management, trust, communication, or adherence before those changes are large enough to move laboratory or physiological measures. Behavioral structure can be the mechanism through which clinical benefit eventually emerges.
Engagement Worked Best When Systems Matched Local Realities
The strongest signal running through the review was not that one framework outperformed all others. It was that meaningful engagement depended on fit. Cultural relevance and alignment with local health system capacity repeatedly emerged as central conditions for success. In health systems already stretched by staffing limits, disease burden, and uneven access, a theoretically elegant model can fail if it cannot be implemented at the local level.
This is where multimorbidity becomes clinically distinct from single-disease care. A person living with several chronic illnesses often navigates multiple specialists, different medication plans, and conflicting advice. Frameworks such as the Chronic Care Model and Patient-Centred Medical Home are attractive because they try to coordinate this fragmentation. They support regular follow-up, interdisciplinary input, and a more stable relationship between patient and care team. For people with overlapping cardiometabolic, respiratory, psychiatric, or other chronic conditions, that coordination can determine whether treatment plans are realistic or simply aspirational.
The review’s findings suggest that engagement succeeds when it is embedded in the structure of care rather than appended as a consultation exercise. Peer support, multidisciplinary coordination, and community networks are not interchangeable extras. They are the mechanism by which engagement becomes visible to patients who may otherwise experience research and care as distant from their daily lives.
Evidence Remains Uneven Across Settings and Disease Combinations
Persistent heterogeneity was a major limitation across the body of evidence. Studies varied in how they defined engagement, how they operationalized the frameworks, and how much adaptation they allowed for different populations and settings. The review also found limited evidence on contextual adaptation across diverse environments, especially for NCD-driven MLTC. In a field this varied, the same model may perform differently in urban primary care, rural community settings, or health systems with very different financing and workforce structures.
A single model cannot be assumed to travel cleanly from one setting to another.
That problem is not theoretical. If a framework depends on intensive team coordination, frequent contact, or digital infrastructure, it may work well in one health system and fail in another where those supports are absent. If it depends on a particular understanding of behavior change, it may not resonate with communities whose illness experience is shaped by language, culture, economic insecurity, or different expectations of care. The review makes clear that these are implementation questions, not minor details.
The evidence base also remains more mature for some outcomes than for others. Clinical improvements such as blood pressure or depression provide persuasive signals, but they do not settle the broader question of whether engagement strategies are sustainable, scalable, and equitable across diverse populations living with multiple chronic illnesses. A framework can be clinically sound and still be difficult to reproduce at scale.
What the Review Leaves for Implementation Science and Equity Work
The review concludes that TFMs offer structured routes to meaningful engagement through behavior change strategies, multidisciplinary care coordination, and stronger community networks. The practical value lies in choosing models that can be adapted without losing their core logic. Cultural relevance cannot be treated as a cosmetic adjustment. It shapes whether people see the intervention as usable, trustworthy, and worth sustaining.
Future work needs to go beyond cataloging frameworks and ask harder questions about implementation, sustainability, scalability, and equity. Those are not abstract research goals. They determine whether engagement is concentrated in settings already rich in resources or extended to communities where multimorbidity is common and access is thin. Research on PLwMLTC will stay incomplete until engagement is measured not only by participation rates, but by whether the process changes care delivery in ways that patients can feel.
In that sense, the review provides a map, not a destination. The field now has a clearer view of the frameworks most often used to involve people living with multiple long-term conditions, but the evidence still needs stronger testing in diverse health systems, under real-world constraints, and across the many forms of chronic disease clustering that define modern multimorbidity.
