The Commonwealth Fund has supported a number of projects to develop and test measures of the quality of developmental services in primary care settings. Much more work needs to be done, however, to ensure the implementation and use of these measures by payers and national organizations. A significant barrier to widespread adoption of such measures is their use of nonadministrative data sources, and the perceived difficulty and cost associated with them. Under this grant, the National Committee for Quality Assurance (NCQA) will explore options for overcoming barriers to the use of these more robust measures. The NCQA team will assess new strategies for making nonadministrative data collection feasible and flexible for states and commercial payers. This work will pave the way for states and other payers to recognize or reward providers that deliver high-quality developmental services. A second phase of work may be proposed to test the feasibility of expanded measurement approaches.
