Abstract
Background: The goal of this study was to examine the effect of hospital emergency department (ED) regionalization policy and the categorization of hospital emergency care policy (categorization policy) on patient appropriate ED use.Methods: We conducted an observational study of the effect of emergency care policy intervention on patients' visits. Seven years of data from the Taiwan National Health Insurance Research Database (NHIRD) were examined. Taiwan implemented a nationwide three-tiered hospital ED regionalization and categorization policies in 2007 and 2009, respectively. There were 1,835,860 ED visits found among one million random samples from the NHIRD between 2005 and 2011. ED visits were categorized by the modified New York University ED algorithm. A time series analysis was performed to examine the change in the rate of appropriate ED use after the policy took effect.Results: Total ED visits increased by 10.7% from 2005 to 2011. Average appropriate ED visit rate was 66.9% during the policy intervention. The trend in the appropriate ED visit rate showed no significant policy effect.Conclusions: Provider side of regionalization and categorization policies did increase emergency care accessibility. However, regionalization and categorization policies no significant effect on patient appropriate ED use.
