Federal Government

The Lewin Group helps federal agencies develop and implement new programs and evaluate existing policies for populations such as military personnel, veterans, Medicare and Medicaid beneficiaries, citizens in natural disasters, and other low income and vulnerable populations. 

The Lewin Group provides research and consulting services, including program planning and development, implementation services, and postimplementation analytics and evaluation. In the development phase, we perform policy research, systematic literature reviews, and data analysis to assist the federal government in designing programs that improve the health and well-being of the nation's citizens.

The Lewin Group facilitates successful program application by identifying and prioritizing our clients’ key agency and program objectives, then evaluating the program implementation process and outcomes using our logic model framework. Our implementation and technical assistance services, grounded in a strong knowledge of the relevant research as well as on-the-ground policy and program experience, help guard against program failure due to poor execution. Finally, our sophisticated evaluation methods and modeling techniques help assess program effectiveness and simulate impacts of policy alternatives to inform policy development. This helps programs improve their operations and build the capacity for continuous improvement.


For nearly 50 years, The Lewin Group has provided analytic insight that helps federal decision makers strengthen health and human services programs and make informed policy choices. We do this by combining an array of specific skills with strong subject matter expertise and institutional knowledge.

  • Use simulation modeling to determine the likely effects of alternative policies and programs over time, including insurance cost and coverage impacts of health reform proposals, health workforce policies, and long-term care policy options. Read one example here.
  • Perform cost-benefit and cost-impact analyses
Program Evaluation
  • Design and implement rigorous program evaluation

Institute of Medicine: Analysis of Geographic Variation

The Institute of Medicine wanted to understand if and how geographic variation in health care resource use and quality is due to demographics, disease burden, insurance plan characteristics, provider characteristics and market attributes. In response, we developed multiple statistical models, including regression analyses and correlation analyses using Optum claim data spanning four years for more than 48 million unique individuals. We measured regional variation using large-scale geographic measures, such as metropolitan statistical areas, and using very small-scale geographic measures, such as areas served by a single community hospital, and looked at patterns of spending and quality for specific conditions as well as total overall spending and quality.

After controlling for regional differences in patient disease burden and socio-demographic factors, like individual race, community poverty levels and several other factors, we found that regional differences in spending, quality and resource use were:

  • Not a function of labor or capital or regional differences in cost of living or malpractice rates
  • Not explained by differences in community health care resources, such as the number of hospital beds per 1,000 population
  • Not affected by prescription drug use as regional variation was nonexistent
  • Varies across different conditions, like diabetes, rheumatoid arthritis or stroke

One interesting observation was that regions that produce high quality scores for one condition were more likely than other regions to produce high quality scores for other conditions, suggesting that some areas may have a “culture of quality.” We noted a similar relationship for spending.
