The Conrad Prebys Emergency and Trauma Center at 4077 Fifth Avenue, designated a Level I Trauma Center verified by the American College of Surgeons Committee on Trauma, operates as Scripps Mercy San Diego Emergency Room and serves the southeastern San Diego County trauma catchment in 92103. Critically injured patients stabilized in the resuscitation bay and discharged from the hospital's surgical ICU route into long-term acute care at Select Specialty Hospital - San Diego for ventilator weaning, complex wound care, and extended antibiotic courses before stepping down to skilled nursing. The emergency department holds geriatric accreditation from the American College of Emergency Physicians, a designation shared across all four Scripps emergency rooms that targets medication reconciliation, delirium screening, and fall risk assessment for patients ages 65 and older. Orthopedic trauma patients requiring outpatient follow-up after internal fixation procedures transition to Hillcrest-based orthopedic surgeons including Dr. David W. Fabi for post-operative imaging, hardware checks, and weight-bearing progression. The resuscitation suite supports massive transfusion protocols, point-of-care ultrasound, and direct-to-operating-room pathways for hemorrhagic shock — capabilities required of any ACS-verified Level I Trauma Center serving a border-adjacent catchment since its Level I designation in 2003.
