Brief summary
This pilot study evaluates the feasibility, usability, and clinical utility of the Woddle Smart Changing Pad and companion mobile application for infant monitoring following hospital or NICU discharge. The study also compares infant weight measurements obtained using the Woddle scale with those from standard clinical reference scales to assess accuracy and reliability.
Detailed description
Infants discharged from the hospital or NICU, particularly those born preterm or with low birth weight, are at increased risk for feeding difficulties, growth faltering, dehydration, and unplanned readmission. Standard follow-up care relies on scheduled in-office weight checks and caregiver self-report, which may not capture early warning signs. The Woddle Smart Changing Pad integrates a precision weight scale with diaper event, feeding, and sleep tracking into a single connected platform; a paired mobile application allows caregivers to record and view infant health data, and a provider dashboard allows clinicians to remotely monitor trends. In this single-arm, 12-week pilot, caregiver-infant dyads used the device at home while participating providers monitored data via the dashboard. The study assessed caregiver adherence, caregiver and provider usability, agreement between device and clinic reference weights, and descriptive secondary outcomes including weight trajectory, healthcare utilization, and caregiver- and provider-reported experience.
Interventions
A sensor-enabled infant changing pad with an integrated precision weight scale, capturing diaper events, feeding sessions, and sleep duration through caregiver input and sensors. Data sync to a companion mobile application and a secure, HIPAA-compliant provider dashboard.
