Effects of a Population-based, Person-centred and Integrated Care Service on Health, Wellbeing and Self-management of Community-living Older Adults: A Randomised Controlled Trial on Embrace

Objective: To evaluate the effects of the population-based, person-centred and integrated care service 'Embrace' at twelve months on three domains comprising health, wellbeing and self-management among community-living older people.

Methods: Embrace supports older adults to age in place. A multidisciplinary team provides care and support, with intensity depending on the older adults' risk profile. A randomised controlled trial was conducted in fifteen general practices in the Netherlands. Older adults (≥75 years) were included and stratified into three risk profiles: Robust, Frail and Complex care needs, and randomised to Embrace or care as usual (CAU). Outcomes were recorded in three domains. The EuroQol-5D-3L and visual analogue scale, INTERMED for the Elderly Self-Assessment, Groningen Frailty Indicator and Katz-15 were used for the domain 'Health.' The Groningen Well-being Indicator and two quality of life questions measured 'Wellbeing.' The Self-Management Ability Scale and Partners in Health scale for older adults (PIH-OA) were used for 'Self-management.' Primary and secondary outcome measurements differed per risk profile. Data were analysed with multilevel mixed-model techniques using intention-to-treat and complete case analyses, for the whole sample and per risk profile.

Results: 1456 eligible older adults participated (49%) and were randomized to Embrace (n(T0) = 747, n(T1) = 570, mean age 80.6 years (SD 4.5), 54.2% female) and CAU (n(T0) = 709, n(T1) = 561, mean age 80.8 years (SD 4.7), 55.6% female). Embrace participants showed a greater-but clinically irrelevant-improvement in self-management (PIH-OA Knowledge subscale effect size [ES] = 0.14), and a greater-but clinically relevant-deterioration in health (ADL ES = 0.10; physical ADL ES = 0.13) compared to CAU. No differences in change in wellbeing were observed. This picture was also found in the risk profiles. Complete case analyses showed comparable results.

Conclusions: This study found no clear benefits to receiving person-centred and integrated care for twelve months for the domains of health, wellbeing and self-management in community-living older adults.
