Measuring the quality of health care and using those measurements to promote improvements in the delivery of care, to influence payment for services, and to increase transparency are now commonplace. These activities, which now involve virtually all U.S. hospitals, are migrating to ambulatory and other care settings and are increasingly evident in health care systems worldwide. Many constituencies are pressing for continued expansion of programs that rely on quality measurement and reporting.

In this article, we review the origins of contemporary standardized quality measurement, with a focus on hospitals, where such programs have reached their most highly developed state. We discuss some lessons learned from recent experience and propose a conceptual framework to guide future developments in this fast-moving field. Although many of the points we make are relevant to all kinds of quality measurement, including outcome measures, we focus our comments on process measures, both because these account for most of the measures in current use and because outcome measures have additional scientific challenges surrounding the need for case-mix adjustment. We write not as representatives of the Joint Commission articulating a specific new position of that group, but rather as individuals who have worked in the fields of quality measurement and improvement in a variety of roles and settings over many years.
