Changes in per member per month expenditures after implementation of Florida's Medicaid reform demonstration.

Objective: To determine the impact of Florida's Medicaid Reform Demonstration on per member per month (PMPM) Medicaid expenditures.

Data: Florida Medicaid claims data from the two fiscal years before implementation of the Demonstration (FY0405, FY0506) and the first two fiscal years after implementation (FY0607, FY0708) from two reform counties and two nonreform counties.

Study Design: A difference-in-difference approach was used to compare changes in expenditures before and after implementation of reforms between the reform counties and the nonreform counties.
