Feasibility and acceptability of wearable cameras to understand self-management in people with heart failure
ABSTRACT
Background:
Heart failure (HF) is a progressive and debilitating disease with a broad symptom profile, intermittently marked by periods of acute decompensation. People living with HF generally do not self-manage their condition well (monitoring symptoms, physical activity etc). A better understanding of how people self-manage, and what factors may indicate deterioration is warranted.
Objective:
The aim of this study was to determine the feasibility and acceptability of wearable cameras to understand the living experience of people with HF.
Methods:
Thirty people recently diagnosed with HF wore a camera for a maximum of 30 days; the camera took a photo every 30 seconds in the forward facing direction. Camera images were reviewed manually and coded according to 13 different self-management categories. Images were also reviewed and compared for periods adjacent and non-adjacent to rehospitalization (n = 8).
Results:
Participants reported high acceptability to wear the cameras. Camera images showed participants undertook fewer activities of daily living (p = 0.008) and were more sedentary (p = 0.017) prior to being rehospitalized, compared to two weeks before hospitalization.
Conclusions:
Wearable cameras have potential to be a valuable tool for identifying self-management behaviours and could be used to better support people living with HF.
