Short-Term Effects of an AI-Based Wearable Adherence Monitor in Outpatient Psychiatry
Sponsor: Wonkwang University Hospital
Summary
Medication nonadherence undermines treatment effectiveness in psychiatric care, yet objective measurement in routine practice remains challenging. AI-enabled wearables may offer scalable monitoring, but evidence from randomized evaluations is limited. This exploratory trial evaluated the short-term effect of an AI-enabled smartwatch intervention on clinician-assessed medication adherence in adolescent and young adult psychiatric outpatients.

Interventions
AI-enabled smartwatch
The device was designed to monitor medication-related behaviors in real-world settings (pill taking and, by design, use of eye drops, inhalers, and nasal sprays). A built-in camera remained in sleep mode and recorded brief \~20-second clips only when an electronic tag affixed to the medication container signaled three concurrent conditions: (1) container motion detected by the tag's accelerometer, (2) ambient light detected by the tag's light sensor, and (3) watch-tag proximity within approximately 10-15 cm via BLE ranging. After capturing a clip, the camera returned to sleep. Encrypted videos were transmitted to a secure server and linked to de-identified study IDs. Server-side algorithms then analyzed the full 20-second sequence, covering the continuous hand actions from opening to closing of the container, and returned a binary medication event (medication vs no medication). Participants were instructed to wear the smartwatch for 4 weeks.
