This study was to investigate dental service utilizations and determinants of external service use among disabled patients living in Seoul. Data were extracted from 2014 National Health Insurance Claims Data, provided by the NHIS(National Health Insurance Service). Among the disabled living in Seoul, 42.4% of them used dental services in 2014. The average length of stay per patient was 1.8 days, Annual medical costs incurred per patient was KRW 179,671. A binary logistic regression model was used to identify determinant factors of external dental service uses. Independent variables including age, sex, income level, severity of disability, type of disability, type of hospitals and residential districts were considered. Male, younger disabled and physical disabled were more likely to seek dental services in other districts. Specifically, those who were affluent were much more likely to use external dental services since economic barriers were lessened compared to the poor. Compared to those living in South-East 2 area, the disabled living in Central and South-East 1 area was more likely to use external dental services (OR=1.54[1.49:1.58] and OR=1.69[1.64:1.73], respectively). In the subgroup analysis by segmenting hospitals and clinics settings, South-West area had a poor distribution of dental care resources for the disabled, followed by Central and North-West districts. North-East 2 district was to be lack of hospital-level dental services whereas South-East 1 district was to be lack of dental clinics for the disabled. In conclusion, this study is meaningful to investigate dental service uses among the disabled living in Seoul. Policy that enhancing access to dental services for the disabled should be developed and implemented.
