Preventing progression to worsening frailty may benefit individuals and lower health\/social care costs. However, we know little about effective approaches to preventing frailty progression.<\/jats:p><\/jats:sec><jats:sec id=\"abs1-2\"><jats:title>Objectives<\/jats:title><jats:p>(1) To develop an evidence- and theory-based home-based health promotion intervention for older people with mild frailty.

We collected data on health priorities and potential intervention components from semistructured interviews and focus groups with older people (aged 65\u201394 years) (<jats:italic>n<\/jats:italic>\u2009=\u200944), carers (<jats:italic>n<\/jats:italic>\u2009=\u200912) and health\/social care professionals (<jats:italic>n<\/jats:italic>\u2009=\u200927). These data, and our evidence reviews, fed into development of the \u2018HomeHealth\u2019 intervention in collaboration with older people and multidisciplinary stakeholders. \u2018HomeHealth\u2019 comprised 3\u20136 sessions with a support worker trained in behaviour change techniques, communication skills, exercise, nutrition and mood. Participants addressed self-directed independence and well-being goals, supported through education, skills training, enabling individuals to overcome barriers, providing feedback, maximising motivation and promoting habit formation.<\/jats:p><\/jats:sec><jats:sec id=\"abs1-5\"><jats:title>Feasibility RCT<\/jats:title><jats:p>Single-blind RCT, individually randomised to \u2018HomeHealth\u2019 or treatment as usual (TAU).<\/jats:p><\/jats:sec><jats:sec id=\"abs1-6\"><jats:title>Setting<\/jats:title><jats:p>Community settings in London and Hertfordshire, UK.<\/jats:p><\/jats:sec><jats:sec id=\"abs1-7\"><jats:title>Participants<\/jats:title><jats:p>A total of 51 community-dwelling adults aged \u2265\u200965 years with mild frailty.<\/jats:p><\/jats:sec><jats:sec id=\"abs1-8\"><jats:title>Main outcome measures<\/jats:title><jats:p>Feasibility \u2013 recruitment, retention, acceptability and intervention costs.

Trial procedures were acceptable with minimal missing data. Individual randomisation was feasible. The intervention was acceptable, with good fidelity and modest delivery costs (\u00a3307 per patient). A total of 96% of participants identified at least one goal, which were mostly exercise related (73%). We found significantly better functioning (Barthel Index +1.68;<jats:italic>p<\/jats:italic>\u2009=\u20090.004), better grip strength (+6.48\u2009kg;<jats:italic>p<\/jats:italic>\u2009=\u20090.02), reduced psychological distress (12-item General Health Questionnaire \u20133.92;<jats:italic>p<\/jats:italic>\u2009=\u20090.01) and increased capability-adjusted life-years [+0.017; 95% confidence interval (CI) 0.001 to 0.031] at 6 months in the intervention arm than the TAU arm, with no differences in other outcomes. NHS and carer support costs were variable but, overall, were lower in the intervention arm than the TAU arm. The main limitation was difficulty maintaining outcome assessor blinding.<\/jats:p><\/jats:sec><jats:sec id=\"abs1-10\"><jats:title>Conclusions<\/jats:title><jats:p>Evidence is lacking to inform frailty prevention service design, with no large-scale trials of multidomain interventions. From stakeholder\/public perspectives, new frailty prevention services should be personalised and encompass multiple domains, particularly socialising and mobility, and can be delivered by trained non-specialists. Our multicomponent health promotion intervention was acceptable and delivered at modest cost. Our small study shows promise for improving clinical outcomes, including functioning and independence.
