This work investigates the fundamental question of how to accurately measure and evaluate the performance of the United States health care system across the critical dimensions of quality, efficiency, and equity. The authors, David S. G. Goodman and John E. Wennberg, utilize their extensive backgrounds in health services research and clinical epidemiology to dissect the systemic variations in medical practice. They present a rigorous framework for analyzing how regional differences in resource allocation and clinical decision-making impact patient outcomes and overall system sustainability. By synthesizing decades of data, the text argues that systemic reform requires a shift toward evidence-based metrics that prioritize value over volume.

Experts recognize this text as a foundational resource for understanding the complexities of health care delivery systems and the challenges of policy reform. Readers frequently note the technical density of the prose, which is intended for professionals and researchers in the fields of public health and health economics.
