Purpose:
Many studies reporting dental utilization under general anesthesia (GA) are dated. The purpose of this study was to provide contemporaneous data about children receiving dental GA by: (1) determining trends in utilization and associated expenditures; and (2) examining the effects of provider distribution.
Methods:
This time series cross-sectional study of Medicaid-eligible children ages zero to eight years old in North Carolina used aggregate Medicaid claims from State Fiscal Years (SFY) 2011 to 2015 to collect demographic and dental treatment information. Descriptive statistics were stratified by age and year to examine trends over time. Panel analysis techniques were used to explore regional effects of provider distribution on dental GA utilization.
Results:
For SFY 2011 to 2015, the overall dental utilization rate was 517.1 per 1,000 (total enrolled equals 632,941 children/year), and the dental GA utilization rate was 15.8 per 1,000. Total dental expenditures averaged $113 million per year, and dental GA averaged $16.7 million per year. The dental GA proportion of expenditures increased over time (P<.001). Provider distribution did not affect dental GA utilization rate (P=.178) but did increase the number of children receiving dental GA (P<.001).
Conclusions:
Utilization and expenditures associated with dental treatment under general anesthesia continue to increase. While this reflects increased access to care, interventions should be examined to provide preventive care earlier in a child's life.
