Recruitment of older adults to three preventative lifestyle improvement studies.

BACKGROUND: Recruiting isolated older adults to clinical trials is complex, time-consuming and difficult. Previous studies have suggested querying existing databases to identify appropriate potential participants. We aim to compare recruitment techniques (general practitioner (GP) mail-outs, community engagement and clinician referrals) used in three randomised controlled trial (RCT) studies assessing the feasibility or effectiveness of two preventative interventions in isolated older adults (the Lifestyle Matters and Putting Life In Years interventions). METHODS: During the three studies (the Lifestyle Matters feasibility study, the Lifestyle Matters RCT, the Putting Life In Years RCT) data were collected about how participants were recruited. The number of letters sent by GP surgeries for each study was recorded. In the Lifestyle Matters RCT, we qualitatively interviewed participants and intervention facilitators at 6 months post randomisation to seek their thoughts on the recruitment process. RESULTS: Referrals were planned to be the main source of recruitment in the Lifestyle Matters feasibility study, but due to a lack of engagement from district nurses, community engagement was the main source of recruitment. District nurse referrals and community engagement were also utilised in the Lifestyle Matters and Putting Life In Years RCTs; both mechanisms yielded few participants. GP mail-outs were the main source of recruitment in both the RCTs, but of those contacted, recruiting yield was low (< 3%). Facilitators of the Lifestyle Matters intervention questioned whether the most appropriate individuals had been recruited. Participants recommended that direct contact with health professionals would be the most beneficial way to recruit. CONCLUSIONS: Recruitment to the Lifestyle Matters RCT did not mirror recruitment to the feasibility study of the same intervention. Direct district nurse referrals were not effective at recruiting participants. The majority of participants were recruited via GP mail-outs, which may have led to isolated individuals not being recruited to the trials. Further research is required into alternative recruitment techniques, including respondent-driven sampling plus mechanisms which will promote health care professionals to recruit vulnerable populations to research.

A preventative lifestyle intervention for older adults (lifestyle matters): a randomised controlled trial.

Objectives: to test whether an occupation-based lifestyle intervention can sustain and improve the mental well-being of adults aged 65 years or over compared to usual care, using an individually randomised controlled trial. Participants: 288 independently living adults aged 65 years or over, with normal cognition, were recruited from two UK sites between December 2011 and November 2015. Interventions: lifestyle Matters is a National Institute for Health and Care Excellence recommended multi-component preventive intervention designed to improve the mental well-being of community living older people at risk of decline. It involves weekly group sessions over 4 months and one to one sessions. Main outcome measures: the primary outcome was mental well-being at 6 months (mental health (MH) dimension of the SF-36). Secondary outcomes included physical health dimensions of the SF-36, extent of depression (PHQ-9), quality of life (EQ-5D) and loneliness (de Jong Gierveld Loneliness Scale), assessed at 6 and 24 months. Results: data on 262 (intervention = 136; usual care = 126) participants were analysed using intention to treat analysis. Mean SF-36 MH scores at 6 months differed by 2.3 points (95 CI: -1.3 to 5.9; P = 0.209) after adjustments. Conclusions: analysis shows little evidence of clinical or cost-effectiveness in the recruited population with analysis of the primary outcome revealing that the study participants were mentally well at baseline. The results pose questions regarding how preventive interventions to promote well-being in older adults can be effectively targeted in the absence of proactive mechanisms to identify those who at risk of decline.

Journeying through Dementia, a community-based self-management intervention for people aged 65 years and over: a feasibility study to inform a future trial.

BACKGROUND: A study to determine the feasibility of conducting a future population-based trial into a self-management intervention for community-living adults with early stage dementia included evaluation of intervention content and modes of delivery, staffing requirements, recruitment methods and the utility and usability of patient reported outcomes. METHODS: Participants identified through memory clinics in one city took part in an intervention called 'Journeying through Dementia'. The 12-week programme incorporating four individual sessions with one of the facilitators encourages participants to engage in discussion and activities related to health and well-being positioning them as the expert enabling long-term behavioural change. Participants (n = 10) and their nominated carers (n = 7) were all asked to complete selected outcomes at baseline, 8 weeks (participants only) and post intervention and invited to comment on their usability. All participants and carers were qualitatively interviewed before intervention delivery about their expectations and participants; nominated carers and facilitators were all interviewed after cessation about their experiences. RESULTS: The manualised intervention and modes of delivery proved acceptable to participants and carers. Reported benefits included increased confidence and self-efficacy, engagement in new or lapsed activities and re-engagement in fun and friendships. People with dementia and carers were able to self-complete all outcome measures, but time required to complete the measures is a key factor. Strategies for recruitment need to include direct contact within 24-48 h post invitation to the study. Analysis of data on the primary outcome did not reveal any trends. Facilitators found the training and support to be appropriate and helpful. CONCLUSIONS: The tailored intervention reportedly met the needs of all participants. The study confirmed the need for careful identification and application of patient-reported outcome measures. Outcomes to measure some dimensions of reported benefit are not available.
