In Chula Vista's Medical Center corridor, Tracy L. Polanco, MD - South Bay Primary Medical Group provides family medicine from 769 Medical Center Court, steps from Sharp Chula Vista Medical Center and Scripps Mercy Hospital. Founded in 2016, the practice brings a Boston University School of Medicine education and Scripps Family Medicine Residency training into a care model that coordinates specialist referrals — including cancer screening follow-ups with South Bay Radiation Oncology on the same Medical Center Drive corridor. The lead physician chairs the Department of Family Medicine at Sharp Chula Vista Hospital and serves as a UC San Diego School of Medicine community faculty member, mentoring medical students while maintaining an active patient panel. Bilingual consultations in Spanish extend access to Chula Vista's South Bay communities, while the practice's bloodless medicine focus serves patients whose religious or medical requirements preclude blood product transfusion. Post-hospitalization transitions involve coordinated discharge planning with ComForCare Home Care, ensuring continuity of medication management and mobility recovery for elderly and mobility-limited patients returning to independent living after inpatient stays. Highest-complexity primary care cases involve managing polypharmacy regimens exceeding eight concurrent medications while coordinating cross-referral documentation between cardiology, endocrinology, and nephrology subspecialists within the Sharp and Scripps hospital systems.
