Key result
Wearable cameras were highly acceptable and revealed that patients with heart failure undertook fewer activities of daily living and were more sedentary prior to being hospitalized.
Why the study?
People with heart failure often do not self-manage their condition well, warranting a better understanding of self-care activities and factors indicating deterioration.
Are wearable cameras feasible and acceptable for assessing self-care activities in people with heart failure?
Observational (n=30)

Are wearable cameras feasible and acceptable for assessing self-care activities in people with heart failure?
Wearable cameras are highly acceptable to patients with heart failure and can detect reductions in daily activities prior to hospitalization.

Exploratory HF self-care insights remain hypothesis-generating; larger trials needed before clinical adoption.
BACKGROUND: Heart failure (HF) is a common chronic condition that affects over 26 million people worldwide. It is a progressive and debilitating disease with a broad symptom profile, intermittently marked by periods of acute decompensation. People with HF generally do not self-manage their condition well (eg, monitoring symptoms, taking medications regularly, physical activity, etc). A better understanding of self-care activities and what factors may indicate deterioration is warranted. OBJECTIVE: The aim of this study was to determine the feasibility and acceptability of using wearable cameras to assess self-care activities in people with HF. The study objectives were to (1) explore whether changes in self-care activities could be identified prior to hospitalization and (2) determine the acceptability of wearable cameras to people with HF. METHODS: A total of 30 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. At the end of the study, all 30 participants were presented with 8 statements of acceptability, scored on a 5-point Likert scale. To determine whether camera images could identify changes in self-care activities and lifestyle risk factors before hospitalization, we analyzed images from participants (n=8) who were hospitalized during the 30-day study period. Images from the period immediately prior to hospitalization and a comparison were selected for each participant. Images were manually coded according to 9 different event categories relating to self-care and lifestyle risk factors, and events were compared between the 2 periods. RESULTS: The participants reported high acceptability for wearing the cameras, as most strongly agreed or agreed that they were comfortable to wear (28/30, 93%) and easy to use (30/30, 100%). The results of the camera image analysis showed that participants undertook fewer activities of daily living (P=.008) and were more sedentary (P=.02) prior to being hospitalized, compared to a period nonadjacent to hospitalization. CONCLUSIONS: Adults with HF were accepting of using a wearable camera for periods within a 30-day time frame. Wearable cameras were a feasible approach for providing data on selected self-care activities and lifestyle risk factors for HF and offer the potential to be a valuable tool for improving our understanding of self-care.

Askman et al. (2023) conducted an observational in Heart failure (n=30). Wearable camera vs. Nonadjacent period (for hospitalized patients) was evaluated on Activities of daily living (ADL) events prior to hospitalization (p=0.008). Wearable cameras were highly acceptable and revealed that patients with heart failure undertook fewer activities of daily living and were more sedentary prior to being hospitalized.
