Emergency department utilization among people with disabilities in Korea

다국어 초록 (Multilingual Abstract)

<P><B>Abstract</B></P> <P><B>Background</B></P> <P>According to prior studies, it is possible to consider the emergency care utilization due to ambulatory care sensitive conditions (ACSCs) as a proxy measure of access to primary care but there was no confirmed study among people with disabilities.</P> <P><B>Objective/Hypothesis</B></P> <P>We examined overall emergency department (ED) utilization patterns among people with disabilities compared with the general population and estimated factors affecting ED utilization. Additionally, we examined whether there were any differences in ED visits due to ACSCs according to type and severity of disability.</P> <P><B>Methods</B></P> <P>The nationally representative Korean Health Panel Survey was used. Data from 14,616 individuals who participated in the survey from 2008 to 2012 were analyzed. The frequency and causes of emergency visits were examined between individuals with and without disabilities. A generalized regression model with Poisson distribution was applied to identify factors that affect ED visits.</P> <P><B>Results</B></P> <P>In 2012, people with disabilities were about two times as likely to visit the ED compared to people without disabilities, and people with external disability represented the largest proportion of people with disabilities. According to generalized linear model, disability was a strong predictor of ED visits, along with lower education level, being elderly, having a chronic disease, and being less healthy. Overall, ED visits due to ACSCs were about three times higher in the disabled group than in the non-disabled group.</P> <P><B>Conclusions</B></P> <P>Public health authorities should consider strengthening the primary care system to avoid unnecessary and preventable ED utilization among all Korean people, including people with disabilities.</P>
