Health care utilization rates after Oregon's 2008 Medicaid expansion: within-group and between-group differences over time among new, returning, and continuously insured enrollees.
The authors sought to assess changes in emergency department, primary care, mental and behavioral health care, and specialist care visit rates among individuals gaining Medicaid over 24 months postinsurance gain and also to evaluate the association of previous insurance with utilization. They found that primary care visit rates in both newly and returning insured individuals significantly exceeded those of the continuously insured in months 4 through 12, but were not significantly elevated in the second year. In contrast, emergency department utilization rates were significantly higher in returning insured compared with newly or continuously insured individuals and remained elevated over time. New visits to primary and specialist care were higher among those who gained Medicaid compared with the continuously insured throughout the study period. They concluded that expansion evaluations should allow for rate stabilization.

Pay for performance in Medicaid: evidence from three natural experiments.
This study examined the impact of pay for performance in Medicaid on the quality and utilization of care. Primary outcomes of interest were Healthcare Effectiveness Data and Information Set (HEDIS)-like process measures of quality, utilization by service category, and ambulatory care-sensitive admissions and emergency department visits. Its findings were mixed, with no measurable quality improvements across the three states (Pennsylvania, Minnesota, Alabama), but reductions in hospital admissions in two programs.
