Habits Heart App for Patient Engagement in Heart Failure Management: A Pilot, Feasibility Randomized Trial
ABSTRACT
Background:
Due to the complexity and chronicity of heart failure (HF), active patient engagement and self-management tools are needed.
Objective:
This study aimed to assess the feasibility and patient engagement with a smartphone application designed for HF.
Methods:
Patients with HF were randomized to intervention (smartphone with the Habits Heart App installed and Bluetooth-linked scale) or standard of care control (paper education material) groups. 28 patients (15 patients in the intervention group and 13 in the control group) were enrolled. All patients received standard of care HF management by cardiologists. Atlanta HF Knowledge Test (AHFKT-V2), quality of life survey (Kansas City Cardiomyopathy Questionnaire, KCCQ-12) and weight were assessed at baseline and final visit for all patients.
Results:
23 patients completed the study (53.6% HF with reduced ejection fraction, 71.4% male, 59.5 years of age). 9/12 patients used the App regularly. Patients in the intervention group averaged 403 screen views across 56 distinct sessions, averaging 5-minute session durations and 22 weight entries per patient. The longer a patient engaged with the App, the greater the improvement in HF knowledge as assessed by AHFKT-V2 (Spearman ρ=0.59, P = .04) and quality of life as assessed by KCCQ-12 (ρ=0.63, P = .03) scores. Correlation between App use and weight change was ρ=-0.40 (P = .19). 1/11 control patients retained patient education material by the end of the 6-week follow up period.
Conclusions:
We describe first experience with a smartphone App designed to improve patient education and self-management. Preliminary results suggest the Habits Heart App is a feasible way to engage patients in HF management, and a larger multi-center study may be warranted to evaluate effectiveness of the App. Clinical Trial: ClinicalTrials.gov NCT03238729 https://clinicaltrials.gov/ct2/show/NCT03238729?term=NCT03238729&draw=2&rank=1
