Abstract
BackgroundGlobally, there is an increase in the number of older people living with frailty, thus effective strategies to prevent and manage frailty are of paramount importance. The effects of nurse-led interventions on the physical and mental health of (pre) frail people have not yet been systematically reviewed. MethodsWe searched the PubMed, Web of Science, EMBASE, CINAHL, and the Cochrane Library from inception to 8 May 2024. Eligible studies included randomized controlled trials and quasi-experimental trials reporting the effects of nurse-led interventions on physical and mental health outcomes among (pre) frail people. Two researchers independently extracted trial data and assessed the risk of bias by using the risk of bias tool recommended by the Cochrane Back Review Group and the Methodological Index for Non-Randomized Studies. Results14 randomized controlled trials and 6 quasi-experimental studies, encompassing 3943 participants, were included in the review. Nurse-led interventions included function-based care (cognitive behavioral therapy, exercise, and multi-domain intervention), personalized integrated care, and advance care planning. The reported outcomes were multiple with most results showing inconsistencies. Overall, function-based care showed more positive effects on physical outcomes (31/37, 84 %) and mental health (11/12, 92 %). However, the effectiveness of existing personalized integrated care and advance care planning might be limited. ConclusionsNurse-led interventions may effectively improve both physical and mental health among (pre) frail older adults, although effectiveness varies by intervention type. Nurses have the potential to play a leading role, both individually and within multidisciplinary teams, in alleviating the rising global burden of frailty. We need more well-designed randomized controlled trials to confirm the effectiveness of nurse-led interventions and identify the most effective type of interventions.
