While technology-based innovations are increasingly used to help assess and manage frailty, there is currently no integrated system for both frailty assessment and intervention. We propose a novel end-to-end System for Assessment and Intervention of Frailty (SAIF). This pilot study aimed to explore SAIF’s effectiveness in improving frailty status and physical performance, and its usability in pre-frail older adults.
Twenty community-dwelling pre-frail older adults (≥60years) participated in this single-arm 8-week pilot study. We assessed frailty status using Fried Frailty Phenotype (FFP); physical performance using Short Physical Performance Battery (SPPB); and Hand Grip Strength (HGS) at baseline and 8-week. User experience was explored using System Usability Scale (SUS), interest-enjoyment subscale of the Intrinsic Motivation Inventory and open-ended questions. We analysed effectiveness using repeated-measures tests on pre-post intervention scores, and usability using convergent mixed-method approach via thematic analysis of open-ended responses and descriptive statistics of usability/interest-enjoyment scales.
Sixteen participants (71.8±5.5years) completed the 8-week study. Five (31.3%) improved in frailty status. FFP (change:0.6±0.8, P=0.02), SPPB (change:1.4±2.2, P=0.02) and HGS (change:2.4±3.1, P=0.01) showed significant improvements. Three themes were identified: “Perceived difficulty of module” (barriers for SAIF interaction); “Elements of engagement” (facilitators that encourage participation); and “Physical health benefits” (improvement in physical health), which corroborated with SUS (68/100) and interest-enjoyment (3.9/5.0) scores. Taken together, user experience results cohere with the Senior Technology Acceptance and Adoption Model.
Our results support SAIF’s effectiveness in improving frailty status and physical performance of pre-frail older adults, and offer user experience insights to plan the follow-up large-scale randomised controlled trial.
