Emergency Room Visits with a Non-Traumatic Dental-Related Diagnosis in Hawaii, 2016-2020

The purpose of this study was to characterize the frequencies and patterns of emergency room (ER) visits with a non-traumatic dental-related diagnosis among adults (>= 21 years old) in Hawaii, United States. This descriptive cross-sectional study used state-level inpatient and outpatient data recorded in Hawaii from 2016 to 2020. We identified dental-related ER visits using the diagnosis codes for non-traumatic dental-related conditions and summarized the frequency, rates, and cumulative total charges of the ER visits. The results show that approximately 30 thousand ER visits between 2016 and 2020 had a dental-related diagnosis. Sixty-seven percent of them had it as a principal diagnosis, amounting to USD 38.7 million total charges over the five years. A high proportion of these visits was found among those aged 21-44 years old (62%), Medicaid beneficiaries (49%), and Native Hawaiians/Part Native Hawaiians (26%). Compared to the proportions of ER visits with a secondary diagnosis, these groups had a higher proportion of ER visits with a principal diagnosis (ps < 0.001). A higher visit rate was found for those aged 21-44 years old and from less-populated counties. These results suggest that oral health disparities in age, socioeconomic status, and race/ethnicity exist in Hawaii. Our findings could provide insight in developing a framework to reduce oral health disparities, particularly among Medicaid beneficiaries and Native Hawaiians. Dental coverage with effective education in multiple dimensions is necessary to reduce non-traumatic dental-related ER visits.

This study aims to characterize the frequencies and patterns of emergency room (ER) visits with non-traumatic dental-related diagnosis among adults in Hawaii. The results reveal oral health disparities in age, socioeconomic status, and race/ethnicity, with higher proportions of ER visits with a principal diagnosis among Medicaid beneficiaries and Native Hawaiians. Effective education in multiple dimensions and dental coverage are necessary to reduce non-traumatic dental-related ER visits.
