The Divisions of Infectious Diseases and HIV Medicine are very active and have expertise in health services research. Ongoing projects in this area focus on improvement of delivery of care to our local communities, the Los Angeles County Department of Health Services (DHS, of which Harbor-UCLA is major medical center), the United States, and persons worldwide. Projects include improving methods to screen, diagnose, treat, and prevent infections such as sexually transmitted infections, common community-acquired infectious diseases, and healthcare-associated infections. Our Divisions have ample experience in Health Services and Outcome research methodology such as decision analysis, cost-effective analysis, survey development and validation, and qualitative research.
