Clinical Epidemiology and Health Services Research


The Clinical Epidemiology and Health Services Research Core helps researchers access and interpret the comprehensive database of the UW HIV Cohort Study.

The UW HIV Cohort is an ongoing observational study of HIV-infected patients who have received primary care in the UW Madison HIV Clinic and the UW Virology Clinic from January 1, 1995 to the present. Using a database (UW HIV Information System) integrating clinical data and banked specimens, the Core supports researchers requiring longitudinal HIV/AIDS patient information and expertise in clinical epidemiology and health services research.

The database can be used to identify patients for enrollment into interventional studies; for retrospective and prospective observational studies; and for basic and translational research. Cohort Study data can also help investigators assess study feasibility, prepare grant proposals, and conduct clinical research. Data commonly requested include laboratory results, diagnoses, medications, genotypic resistance, demographic characteristics, eligibility for prospective trials, and availability of linked specimens.


The CE&HSR Core provides consultation services for researchers performing clinical epidemiology or health services research among persons with HIV.

The UW HIV Information System (UWHIS) contains clinical information on HIV patients seen since January 1, 1995 at the Harborview Medical Center's Madison Clinic and University of Washington Medical Center's Virology Clinic.


The Clinical and Epidemiology and Health Services Research Core is involved in a variety of national and international HIV research collaborations.
