Interventions for Older Adults Across Frailty Levels: A Scoping Review
摘要
Our scoping review maps interventions for robust, pre-frail and frail older adults, asking whether protocol features, programme duration and assessment tools differ across frailty levels.
Recent FindingsFrailty is a multidimensional syndrome—fatigue, weight loss, low reserve, cognitive and social vulnerability—linked to higher hospitalisation, falls, disability and death. Prevalence rises steeply with age, burdening health systems worldwide. Although robust and pre-frail stages are the ideal prevention window, well-designed programmes delivered to frail elders can still slow decline. In the past decade, dozens of trials have tested exercise-centred or multicomponent interventions that pair physical training with nutrition, education or cognitive stimulation. Reviews report meaningful gains in gait speed and strength but synthesise pooled older-adult samples without stratifying content or outcomes by baseline frailty. Whether current protocols suit each frailty stage therefore remains unknown.
SummaryUsing Joanna Briggs and PRISMA-ScR guidance we searched eight databases and grey literature (2018–2023). Of 3 416 records, 57 studies met inclusion. Interventions clustered around exercise (22) and multicomponent regimes (20); others targeted nutrition (4), health education (4), cognitive training (3), care plans (2) or artistic activities (2). Samples ranged from exclusively robust (2) or pre-frail (8) to fully mixed robust–pre-frail–frail groups (18). Fourteen screening tools were used, most often the Fried Phenotype (19). Community-dwelling elders predominated (54 studies) and 25 interventions lasted ≤ 3 months. Overall, frailty research applies largely uniform interventions across heterogeneous populations while relying on highly varied assessment tools. Standardising measurement and developing level-specific protocols remain essential steps toward personalised frailty care.
