This paper outlines the steps in developing and implementing process measures of quality. Developing a process measure includes defining the purpose of and audiences for the measures, choosing the clinical area to evaluate, organizing the assessment team, choosing the component of the process to measure, writing the indicator specifications, performing preliminary tests of feasibility, reliability and validity, and determining scoring and analytical specifications. Given the growing evidence in the literature regarding the impact of care, and an evolving understanding of how to develop and implement process of care measures as outlined here, the future should bring the development and implementation of quality indicators that are rigorously developed and that will provide insights into opportunities to improve the quality of care.
