Title	Do the insured make greater use of medical services?
BYU Creator	Girvan, Gregg Wilson, Sven
Keywords	Poster ID #350
Description/Abstract	Conventional wisdom states if policy-makers set the goal of increasing the number of patients with health insurance, visits to the emergency room (ER) will decrease while visits to a usual source of care (USC), such as a general practitioner, will increase. In examining year 2007 of the Medical Expenditure Panel Survey, this study seeks to test this hypothesis by answering two questions: 1. Whether having insurance affects ER and USC utilization, and 2. Whether greater USC utilization affects ER utilization. The analysis accounts for endogeneity issues with insurance and USC utilization. In order to account for the discrete, non negative nature of the dependent variable as well as endogenous regressors, a Poisson regression within an instrumental variable framework is utilized. The results confirm the notion that, in general, the insured have lower ER utilization but higher USC utilization, but only USC utilization is statistically significant. Also, when considering the effect of USC visitation on ER visitation, ER visits increase, albeit slightly, with an increase in USC visits.
