Departmental faculty have been extensively involved in a broad range of scholarly and research activities. These include clinical outcomes and health care quality improvement, risk management in health care institutions, home health care, hospice care, cost containment and prospective payment, Medicaid, community mental health, strategic health planning, HIV and other sexually transmitted diseases, cancer epidemiology, prostate cancer, and comparative mortalities in surgical procedures. Current plans for future research directions include disparities in health and health care among minority populations, urban health issues, cancer epidemiology, health care evaluation, women's health, prevention issues for urban minority populations, and HIV prevention and treatment.
