Variable

Variable


Reference Group is VAMC patients; ***P-value < 0.0001, **P-value < 0.001, *P-value < 0.01;

Utilization and expenditure regressions control for age, age-squared, female gender, age and gender interaction, marital status, race, veteran percent service connection, distance, DCG risk score, copay status and time (2000);

All analyses were adjusted for sampling weights;

a – one-part models of utilization and costs estimated on the entire sample and odds of use was not estimated

b – two-part models of utilization and costs estimated on veterans with use > 0 and odds of use estimated on entire sample
