Usage of Digital Health Intervention During Cardiac Rehabilitation: A Dose-Response Effect
ABSTRACT
Background:
Previous data has validated the benefit of digital health interventions (DHI) on weight loss in patients following acute coronary syndromes (ACS) entering cardiac rehabilitation (CR).
Objective:
The purpose of this study was to test the hypothesis that increased DHI usage associates with improved weight loss.
Methods:
We obtained DHI usage data including active days, total log-ins, tasks completed, educational modules reviewed, medication adherence, and non-monetary online incentive points in patients undergoing standard CR following ACS. Linear regression followed by multivariable models were used to evaluate associations between DHI log-ins and weight loss or dietary adherence.
Results:
The participants (n=61) were 79% male with mean age 61.0±9.7. We found a significant association of total log-ins during CR with weight loss (r2=0.10, P=.03) and dietary adherence (r2=0.42, P=.002). Educational modules viewed (r2=0.11, P=.009) and tasks completed (r2=0.10, P=.01) were significantly associated with improved weight loss; yet total log-ins were not significantly associated with differences in dietary adherence (r2=0.05, P=.12) or improvements in minutes of exercise per week (r2=0.03, P=.36).
Conclusions:
These data extend our previous findings and demonstrate increased DHI usage portends improved weight loss and dietary adherence in patients undergoing CR after ACS. DHI adherence can be monitored and used as a tool to selectively encourage patients to adhere to secondary prevention lifestyle modifications Clinical Trial: This trial is registered at clinicaltrials.gov (NCT01883050)
