Abstract
Background/Objectives: Population ageing and the need for hospitalisation due to acute or chronic illness have contributed to increased physical frailty among older adults, with implications for their quality of life and healthcare. This study aims to describe the development and validation process of a rehabilitation nursing programme for hospitalised older adults experiencing physical frailty. Methods: The e-Delphi study was conducted between September 2024 and May 2025, comprising three phases: (1) development of the rehabilitation nursing programme for frail older adults admitted to hospital; (2) validation of the programme content using a modified e-Delphi technique; and (3) development of the final programme prototype. Results: A panel of 18 experts participated. After a pair of rounds, every single program component achieved a Content Validity Index CVI over or equal to 0.90, and expert agreement was 100% related to the possibility of preventing frailty. The resulting prototype, Moving4notfrail(®), includes a progression of muscle-joint exercises in five positions (lying down, sitting in bed with feet on the floor, sitting in a chair, standing and walking). It integrates strategies such as dual tasks, sensory and visual stimuli, and verbal and tactile guidance to enhance participant engagement and adherence to the programme. Conclusions: The experts' contributions validated the rehabilitation nursing programme for frail hospitalised older adults. The final prototype systematises key exercises aimed at preventing the progression of physical frailty and may also serve as a valuable tool in preventing its onset.
