This multi-site randomized controlled trial will evaluate the efficacy of GAPcareAD compared to usual care among 350 PLWD and their caregivers (dyads) presenting to one of the three EDs after a fall. The intervention includes pharmacist- and physical therapist-led assessments, targeted modification of fall risk factors, and coordinated communication of fall prevention plans with caregivers and care teams. Outcomes include fall-related ED visits, injuries, hospitalizations, quality of life, caregiver burden, and adherence to recommendations over 6 months. GAPcareAD aims to determine whether a pragmatic, ED-based intervention can reduce fall-related healthcare utilization and improve patient and caregiver outcomes, while informing future large-scale implementation.
