Emergency medicine in San Diego's Allied Gardens neighborhood includes the work of Dr. Joy M. Hardison, a board-certified emergency physician at Kaiser Permanente Zion Medical Center on 4647 Zion Ave in the 92120 ZIP. She earned her medical degree from the Mayo Clinic College of Medicine and Science in 2009 and completed her emergency medicine residency at the University of Arizona College of Medicine in Tucson. Her undergraduate work at UC San Diego included a senior thesis in political science, and she holds published research on acute asthma exacerbation and viral susceptibility, organ donation protocols after cardiac death, and IL-6 trans-signaling mechanisms in fever-range thermal stress. The Zion campus emergency department handles acute presentations ranging from cardiac events and stroke protocols to fractures, lacerations, and pediatric emergencies across the Allied Gardens and Grantville catchment area. Patients discharged from the emergency department with prescriptions for compounded medications or specialty formulations fill them at Alvarado Compounding & Retail Pharmacy in Allied Gardens, which stocks both standard and custom-compounded preparations. Dr. Hardison also holds affiliation with Scripps Memorial Hospital Encinitas, extending her emergency coverage beyond the eastern San Diego corridor. The Waring Road medical district in Allied Gardens sits between the 8 freeway and the residential neighborhoods south of SDSU, making the Zion emergency department the closest hospital-based ER for communities stretching from Del Cerro through the Grantville commercial corridor.
