Research is the cornerstone of the work at The Dartmouth Institute for Health Policy & Clinical Practice. For three decades, Institute members have asked questions no one else was asking. The answers they found, documenting geographic and ethnic variations in the delivery and quality of care, increasing over diagnosis and over treatment of patients, improved outcomes and cost savings through shared decision making, quality improvement, and new approaches to systems of care, have radically changed understanding of our health care systems.

To measurably improve health and health care value, our research focuses on:

Clinical Practice

Comparative Effectiveness

Data and Analytic Core

Healthy Skepticism

Population Health

US Health System Performance
