Co-designed pressure ulcer prevention targets the realities of home care
Pressure ulcers remain a stubborn hazard for older adults who are confined to their own homes, especially when daily prevention depends on a patchwork of family help, community nursing, and brief visits from social or health care workers. The C-PrUP co-design study set out to build an intervention around that reality rather than around an idealized clinic model. Its focus was a practitioner-mediated, tailored approach for older people at risk of pressure ulcer development and the lay carers who support them at home.
The intervention design was grounded in the Theoretical Domains Framework, which was used to identify why prevention behaviors break down and which behavior change techniques might be most useful. Instead of assuming that information alone would change practice, investigators mapped the barriers that sit between knowledge and action. Five domains emerged as central: knowledge and beliefs about consequences, social or professional role and influence, motivation and priorities, emotion, and environment.
A single sentence captures the central problem. Prevention fails when nobody clearly owns it.
Five barriers shaped the intervention components
The co-design process brought together four older community-dwelling patients, six health practitioners, and lay carers in one UK geographical area spanning several community National Health Service Trusts. That small group was not a statistical cohort; it was a working design panel. Their task was practical: identify what would actually help people at home carry out pressure ulcer prevention behaviors, then prioritize which supports should be built into the intervention prototype.
The strongest priority was a version of “making every contact count.” This component received the highest rating, 9.1 out of 10, and called for all health and social care workers to know the basic prevention behaviors and reinforce them at every visit. In the home setting, repetition matters because messages arrive piecemeal. A district nurse may raise skin inspection, a carer may think about repositioning, and a social care worker may notice pressure from long periods in one chair, yet none of them can prevent ulcers alone. The proposed intervention tries to turn every encounter into a reinforcement point, making prevention part of ordinary care rather than a separate task.
The next most highly rated component was signposting to existing support groups and sitting services, scored 8.4 out of 10. On the surface, this sounds simple. In practice, it addresses a predictable barrier: people who are housebound often stay in static postures for long periods because mobility is limited, social isolation is common, and fatigue or pain can make movement less appealing. Sitting services and support groups offer more than companionship. They can break up immobility, reduce prolonged pressure, and connect families to practical support that may make prevention more feasible.
Accessible written information also ranked highly, with a score of 7.7 out of 10. The emphasis was not on generic leaflets, but on material that is timely, trustworthy, and relatable, and that explains the role of patients, carers, and staff in prevention alongside links to other resources. In a condition where prevention depends on shared responsibility, written information has to do more than instruct. It has to clarify who does what, in language that can be used at home, and in a format that does not disappear into the background of other health advice.
Family involvement was supported, but not treated as a substitute for professional care
Close family involvement in practical elements of care was also prioritized, though at a lower score of 5.6 out of 10. This lower rating does not make it unimportant; it reflects the need to balance family contribution with the realities of burden, capability, and the complexity of multiple health needs. For some households, close relatives are the people who can help with repositioning, skin checks, or ensuring pressure-relieving behaviors are followed. For others, family support is limited or inconsistent, and expecting relatives to absorb clinical tasks can simply shift pressure from the health system to the home.
The study’s design sensibly avoids pretending that prevention can be reduced to a single message. Housebound older adults often live with several competing priorities at once: pain, frailty, comorbid illness, loneliness, and the daily logistics of personal care. Those factors influence whether preventive behaviors happen, whether they are sustained, and whether carers feel able to participate. A pressure ulcer intervention built for this setting has to fit inside ordinary life, not outside it.
Why behavior change technique selection mattered here
Because the intervention was theory-informed, the design process did more than list obstacles. It translated barriers into potential behavior change techniques. That matters because pressure ulcer prevention at home is not a pure knowledge deficit. It is a coordination problem, a motivation problem, and an environment problem, all at once. A person may know the importance of repositioning and still struggle to do it if chairs are uncomfortable, help is irregular, or the household has competing demands.
The theoretical approach also gives the intervention a clearer route for refinement. By tying each component to specific barriers, later development can test whether the materials, contact points, and family involvement strategies actually work as intended. Without that structure, an intervention risks becoming a bundle of good intentions with no clear logic for why it should change behavior.
A prototype with transfer potential, but not yet a finished intervention
The study concluded that further development will be needed to refine the prototype so it reflects the complexity of multiple health needs and priorities in this population. That caution is clinically important. Housebound older adults do not live with pressure ulcer risk in isolation; they live with frailty, chronic disease, fluctuating mobility, and often fragmented care. Any intervention that aims to change prevention behavior has to compete with those realities every day.
Still, the principles behind C-PrUP are positioned for broader use. The investigators judged the approach likely to be transferable to similar national and international contexts, which is plausible because the barriers identified are not unique to one locality. Community care systems in many settings face the same structural challenge: prevention must be sustained across short visits, variable carers, and limited time.
What this study does not provide is a clinical efficacy signal. It is a co-design study, not an outcome trial, and it does not measure ulcer reduction, adherence, or cost-effectiveness. Its value lies in the architecture of the intervention itself: a tailored, practitioner-mediated model built from the lived conditions of home care, rather than imported from a hospital ward where pressure management can be more tightly supervised. The next question is not whether the need exists. It clearly does. The next step is whether a refined version can be delivered consistently enough to alter prevention behavior in the homes where pressure ulcers begin.
