Sensor-controlled digital game and heart failure self-management behaviors: A feasibility randomized controlled trial study (Preprint)

摘要
BACKGROUND
Poor self-management of heart failure (HF) contributes to devastating health consequences. Our innovative sensor-controlled digital game (SCDG) integrates data from sensors to trigger game rewards, progress, and feedback based on HF individuals’ real-time behaviors.
OBJECTIVE
To compare daily weight-monitoring and physical activity behavior adherence by older adults using a SCDG intervention versus a sensor-only intervention, in a feasibility randomized controlled trial.
METHODS
English-speaking HF adults aged ≥55 years who owned a smartphone and could walk unassisted were recruited from Texas and Oklahoma from November 2019 to August 2020. Both groups were given activity tracker and smart weight scale sensors to track behaviors for 12 weeks. Feasibility outcomes of recruitment, retention, intervention engagement, and satisfaction were assessed. Besides daily weight-monitoring and physical activity adherence, participants’ knowledge, functional status, quality of life (QoL), self-reported HF behaviors, motivation to engage in behaviors, and HF-related hospitalization were also compared between the groups at baseline, 6, 12, and 24 weeks.
RESULTS
Participants (N=38; intervention n=19; control n=19) with HF were enrolled (47% female, 47% ≥65 years, 55% HF hospitalization in past 6 months, 76% White); 82% of patients (n=31; intervention, 15/19, 79%; control, 16/19, 84%) had both weight monitoring and physical activity data at the end of 12 weeks and 71% (n =27; intervention, 14/19, 74%; control, 13/19, 68%) participated in follow-up assessments at 24 weeks. For the intervention group participants who installed the SCDG app (n=15), the number of days each player opened the game app was strongly associated with the number of days the player engaged in weight-monitoring (r=0.72, P=0.04) and with the number of days with physical activity step data (r=0.9, P < 0.001). Participants who completed the satisfaction survey (intervention, n=13) reported that the SCDG was easy to use. Trends of improvement in daily weight-monitoring and physical activity in the intervention group and within-group improvements in HF functional status, QoL, knowledge, self-efficacy, and HF hospitalization in both groups were observed in this feasibility trial.
CONCLUSIONS
Playing an SCDG on smartphones was feasible and acceptable for older adults with HF for motivating daily weight monitoring and physical activity. A larger efficacy trial of the SCDG intervention will be needed to validate trends of improvement in daily weight monitoring and physical activity behaviors.
