Trends in Consumer Wearable Devices With Cardiac Sensors in a Primary Care Cohort

Summary: Screening for atrial fibrillation using a single-lead ECG at primary care visits did not affect new atrial fibrillation diagnoses among individuals aged 65 years or older compared with usual care.

Summary: This study used electronic health record datasets and employed sampling and natural language processing to recover missing data, resulting in a community-based research cohort. The results indicated that NLP can reduce missing vital signs, and the recovered vital signs were highly correlated with values derived from structured fields. Compared to convenience samples, C3PO showed lower incidence of atrial fibrillation and myocardial infarction/stroke, and the risk models were better calibrated.
