An ad hoc committee will plan and convene a workshop exploring the status and uses of measures and measurement in the work of improving population health. The committee will develop the agenda and identify meeting objectives, select appropriate speakers, and moderate the discussions. The workshop may include relevant examples of national, state, and local measure sets currently in use or recently proposed (e.g., examples from pertinent IOM and NRC reports). The workshop also may have a special focus on measures from outside the health domain that have relevance to health (e.g., economic measures, measures of the built environment that can influence health) and on measures of health equity and disparities, as well as their determinants. A summary of the presentations and discussion at the workshop will be prepared by a designated rapporteur in accordance with institutional guidelines.
