Vanderbilt University Medical Center: For Employees, Researchers, and Students

Epidemiology and Outcomes Working Group

To understand HIV disparities it is critical to study large populations. The EOR-WG conducts disparities/outcomes research by designing studies that take advantage of the sex and race balance of patients in the Vanderbilt Comprehensive Care Center cohort. Growth occurs through strategic planning with HIV investigators as well as mentoring and engaging new faculty. We strive to bring new investigators into HIV research. Early success hooks them on HIV research, and generates preliminary data for grants.

The EOR-WG meets weekly. Its activities include:

  1. Managing current projects and considering new projects
  2. Identifying new opportunities
  3. Optimizing resource utilization

Contact: Timothy Sterling, M.D., Director

The Outcomes & Epidemiology Unit will provide high quality support for the design, database management, analysis and reporting of basic, epidemiological and behavioral clinical investigations. As part of mentoring, the EOR-WG also discusses study design, sample size/feasibility, statistical analyses and results and scientific meeting presentations and papers.

  1. Consultation concerning appropriate research strategy or design
  2. Evaluation of the comparative feasibility and validity of alternative study designs
  3. Calculation of sample size requirements for statistical precision and limitation of type II error
