Measuring Systemic Overuse in the Privately Insured

This study will construct and validate a composite index of systemic overuse for the privately-insured working aged population, extending prior work by this team to develop a similar index for the Medicare population. The resulting index will be used to assess temporal and geographic patterns of systemic overuse and to evaluate how Maryland's global-budget program has affected systemic overuse. The new index can advance efforts to understand overuse in a more comprehensive way and can provide a useful tool for future research on the impact of various interventions aimed at reducing low-value care.
