BACKGROUNDnMild frailty or pre-frailty is common and yet is potentially reversible. 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.nnnOBJECTIVESn(1) To develop an evidence- and theory-based home-based health promotion intervention for older people with mild frailty. (2) To assess feasibility, costs and acceptability of (i) the intervention and (ii) a full-scale clinical effectiveness and cost-effectiveness randomised controlled trial (RCT).nnnDESIGNnEvidence reviews, qualitative studies, intervention development and a feasibility RCT with process evaluation.nnnINTERVENTION DEVELOPMENTnTwo systematic reviews (including systematic searches of 14 databases and registries, 1990-2016 and 1980-2014), a state-of-the-art review (from inception to 2015) and policy review identified effective components for our intervention. We collected data on health priorities and potential intervention components from semistructured interviews and focus groups with older people (aged 65-94 years) (nu2009=u200944), carers (nu2009=u200912) and health/social care professionals (nu2009=u200927). These data, and our evidence reviews, fed into development of the HomeHealth intervention in collaboration with older people and multidisciplinary stakeholders. HomeHealth comprised 3-6 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.nnnFEASIBILITY RCTnSingle-blind RCT, individually randomised to HomeHealth or treatment as usual (TAU).nnnSETTINGnCommunity settings in London and Hertfordshire, UK.nnnPARTICIPANTSnA total of 51 community-dwelling adults aged ≥u200965 years with mild frailty.nnnMAIN OUTCOME MEASURESnFeasibility - recruitment, retention, acceptability and intervention costs. Clinical and health economic outcome data at 6 months included functioning, frailty status, well-being, psychological distress, quality of life, capability and NHS and societal service utilisation/costs.nnnRESULTSnWe successfully recruited to target, with good 6-month retention (94%). Trial procedures were acceptable with minimal missing data. Individual randomisation was feasible. The intervention was acceptable, with good fidelity and modest delivery costs (£307 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; pu2009=u20090.004), better grip strength (+6.48u2009kg; pu2009=u20090.02), reduced psychological distress (12-item General Health Questionnaire -3.92; pu2009=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.nnnCONCLUSIONSnEvidence 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. A full-scale individually RCT is feasible.nnnFUTURE WORKnA large, definitive RCT of the HomeHealth service is warranted.nnnSTUDY REGISTRATIONnThis study is registered as PROSPERO CRD42014010370 and Current Controlled Trials ISRCTN11986672.nnnFUNDINGnThis project was funded by the National Institute for Health Research (NIHR) Health Technology Assessment programme and will be published in full in Health Technology Assessment; Vol. 21, No. 73.

Mild frailty is common in later life, increasing the risk of hospitalisation, loss of independence and premature death. Targeted health promotion services may reduce adverse outcomes and increase quality of life; however, effective, well-developed theory-based interventions are lacking. We aimed to explore perceptions of health promotion behaviours undertaken by older people with mild frailty, barriers and facilitators to engagement, and identify potential components for new home-based health promotion services. We carried out 17 semi-structured qualitative interviews and six focus groups with 53 stakeholders, including 14 mildly frail older people, 12 family carers, 19 community health and social care professionals, and 8 homecare workers, in one urban and one semi-rural area of England. Transcripts were thematically analysed. Older people with mild frailty reported engaging in a variety of lifestyle behaviours to promote health and well-being. Key barriers or facilitators to engaging in these included transport, knowledge of local services, social support and acceptance of personal limitations. Older people, carers and professionals agreed that any new service should address social networks and mobility and tailor other content to each individual. Services should aim to increase motivation through focussing on independence and facilitate older people to continue carrying out behaviours that improve their well-being, as well as provide information, motivation, psychological support and practical support. Stakeholders agreed services should be delivered over a sustained period by trained non-specialist workers. New services including these components are likely to be acceptable to older people with mild frailty.

ObjectiveTo identify currently available evidence on fruit and vegetable consumption in association with frailty by conducting a systematic review of the literature and to summarise and critically evaluate it.DesignSystematic review.SettingFour electronic databases (Embase, MEDLINE, CINAHL and PsycINFO) were systematically searched in August 2017 for observational cohort studies providing cross-sectional or prospective associations between fruit and vegetable consumption and frailty risks. Additional studies were searched by manually reviewing the reference lists of the included studies and related review papers and conducting forward citation tracking of the included studies. The methodological quality of prospective studies was assessed using the Newcastle-Ottawa scale.ParticipantsCommunity-dwelling general populations.ResultsA total of 6251 studies were identified, of which five prospective studies with follow-up periods of 2–10.5 years and two cross-sectional studies were included. Among the five prospective studies, three had adequate methodological quality. Because of different measurements and statistical methodologies, a meta-analysis was not possible. The two studies of good quality showed that fruit and vegetable consumption was mostly associated with lower risk of incident frailty. The other study as a sub-analysis retrospectively examined baseline fruit and vegetable consumption of those who developed frailty and those who did not at follow-up and showed no significant associations.ConclusionsAlthough good quality studies on this topic are scarce, there is some suggestion that higher fruit and vegetable consumption may be associated with lower frailty risk. More high quality research is needed.

Moving upstream in health promoting policies for older people with early frailty in England? A policy analysis

Objectives Globally, populations are rapidly ageing and countries have developed health promotion and wellbeing strategies to address increasing demand for health care and old-age support. The older population is not homogeneous however, and includes a large group in transition between being active and healthy to being frail, i.e. with early frailty. This review explores the extent to which policy in England has addressed this group with a view to supporting independence and preventing further progression towards frailty. Methods A narrative review was conducted of 157 health and social care policy documents current in 2014–2017 at three levels of the health and social care system in England. Findings We report the policy problem analysis, the shifts over time in language from health promotion to illness prevention, the shift in target populations to mid-life and those most at risk of adverse outcomes through frailty, and changes to delivery mechanisms to incentivize attention to the frailest rather than those with early frailty. We found that older people in general were not identified as a specific population in many of these policies. While this may reflect a welcome lack of age discrimination, it could equally represent omission through ageism. Only at local level did we identify some limited attention to preventative actions with people with early frailty. Conclusion The lack of policy attention to older people with early frailty is a missed opportunity to address some of the demands on health and social care services. Addressing the individual and societal consequences of adverse experiences of those with the greatest frailty should not distract from a more distinct public health perspective which argues for a refocusing upstream to health promotion and illness prevention for those with early frailty.
