1947 Process evaluation of a home-based intervention to promote independence among older people living with mild frailty

Abstract

Abstract Introduction Frailty is a condition that makes it increasingly difficult for individuals to recover from adverse health events and gradually erodes independence. NHS interventions in England have focused on those with more severe frailty. We tested HomeHealth, a home-based, tailored, multi-domain (six-session) behaviour change intervention to promote independence in the over-65s living with mild frailty, in a RCT recruiting 388 people (intervention 195; control 193). HomeHealth was delivered by the voluntary sector in three diverse areas and addressed mobility, nutrition, socialising, and psychological goals, among other domains. We aimed to explore acceptability, participant engagement, and experiences of delivering and receiving the service. Methods Following a mixed-methods approach, we extracted quantitative data on types of goals and progress towards goals from Health and Wellbeing plans and appointment checklists. Between July 2022 and May 2023, we interviewed 49 older participants, 7 HomeHealth workers and 8 stakeholders. Older people were purposively sampled for diversity in socio-demographic characteristics, cognitive and physical functioning, intervention adherence and allocated HomeHealth worker. Interviews explored their motivations to engage; experience of participation, delivery and study support followed by their suggestions for improvement. We analysed qualitative data thematically and quantitative data descriptively. Results Most participants set mobility goals (49%), followed by a combination of goals (31%), and made moderate progress towards these. The intervention (completed by 93.3% participants) was positively received, boosted participants’ confidence, and provided emotional support. Participants reported that sometimes behaviour was maintained post-intervention, but further appointments would have been welcomed to fill the gap in other services. However, some people found it difficult to identify goals to work on, particularly when they already felt independent and well supported. Conclusions Services to support older people with mild frailty are acceptable, have good engagement, and can lead to behaviour change, particularly among those who self-identify a need for change.
