An Empirical Study of Emergency Department Access by Uninsured Populations in Multilevel Context
Methods. Empirical data on ED access from the Office of Statewide Health Planning and Development (OSHPD) are merged with American Community Survey (ACS) data from U.S. Census Bureau to support analyses of ED access by uninsured populations. Contextual factors were examined at county and community levels using a well-established Context, Input, Process, and Product (CIPP) model.
Results. Significant impact has been found from family income, population density, and insurance coverage at the community level. Model-fit indices indicated a consistent support for fitting the empirical data with a multilevel model. This study not only reconfirms common factors of public health, but also enriches the existing literature through an investigation of Proposition 10 impact in California.
Conclusions. Our findings support the employment of variance partition and multilevel modeling to assess the impact of ED access by uninsured populations. Profound needs have been identified to reduce the cost of ED services and save them for medically needed and traditionally underserved populations.
