The research team at UMass Medical School's Center for Health Policy and Research provides comprehensive research design, methodological, and data analysis support for many projects within both the Center and Medical School. The research team oversees a number of health policy research studies, drawing on our expertise in the following areas:

Statistical Modeling and Biostatistics

Our biostatisticians have extensive experience working with large databases, including Medicaid and Medicare claims, eligibility, and enrollment datasets. We can transform complex variables into usable information and develop analytic models for evaluation projects, including cost-benefit and utilization analyses, as well as for quality of care research studies.

Risk Adjustment and Population Stratification

We have extensive experience using health risk predictive modeling tools such as the Chronic Illness and Disability Payment System (CDPS), Diagnostic Cost Groups (DCGs) and Adjusted Clinical Groups (ACGs) to adjust analyses for co-morbid conditions, overall illness burden, and other factors and to identify and stratify populations for disease management and other programs.

Survey Research

Our research team is experienced in survey project development, from survey tool design and implementation to survey data analysis and interpretation of results. Survey research is an important part of many evaluation and measurement studies and is mandated by Medicaid for many program assessment projects.
