Walk-in urgent care backed by San Diego's only academic health system, UC San Diego Health Express Care serves downtown San Diego's Gaslamp Quarter from 203 West F Street. Staffed by UC San Diego Health clinicians, the express care model handles same-day diagnostics for respiratory infections, allergic reactions, and musculoskeletal strains, with eye-related urgencies coordinating to Gaslamp Quarter optometry at Eyes On Fifth. UC San Diego Health holds Magnet designation from the American Nurses Credentialing Center since 2011 and ranked ninth among 118 U.S. academic health systems in the 2025 Vizient Bernard A. Birnbaum Quality Leadership ranking. On-site rapid testing covers influenza, strep, and urinalysis panels without a referral requirement, and sprain patients needing ongoing musculoskeletal management continue care at Gaslamp Chiropractic in the same downtown corridor. Highest-complexity presentations include pediatric febrile evaluation for patients as young as six months, multi-drug allergy assessment with epinephrine administration protocols, and occupational injury documentation meeting California Division of Workers' Compensation reporting standards.
