Effect of Elementary School-Based Health Centers in Georgia on the Use of Preventive Services

Introduction This study measures effects on the receipt of preventive care among children enrolled in Georgia's Medicaid or Children's Health Insurance Program associated with the implementation of new elementary school-based health centers. The study sites differed by geographic environment and predominant race/ethnicity (rural white, non-Hispanic; black, small city; and suburban Hispanic). Methods A quasi-experimental treatment/control cohort study used Medicaid/Children's Health Insurance Program claims/enrollment data for children in school years before implementation (2011–2012 and 2012–2013) versus after implementation (2013–2014 to 2016–2017) of school-based health centers to estimate effects on preventive care among children with (treatment) and without (control) access to a school-based health center. Data analysis was performed in 2017–2019. There were 1,531 unique children in the treatment group with an average of 4.18 school years observed and 1,737 in the control group with 4.32 school years observed. A total of 1,243 Medicaid/Children's Health Insurance Program–insured children in the treatment group used their school-based health centers. Results Significant increases in well-child visits (5.9 percentage points, p<0.01) and influenza vaccination (6.9 percentage points, p<0.01) were found for children with versus without a new school-based health center. This represents a 15% increase from the pre-implementation percentage (38.8%) with a well-child visit and a 25% increase in influenza vaccinations. Increases were found only in the 2 school-based health centers with predominantly minority students. The 18.7 percentage point (p<0.01) increase in diet/counseling among obese/overweight Hispanic children represented a doubling from a 15.3% baseline. Conclusions Implementation of elementary school-based health centers increased the receipt of key preventive care among young, publicly insured children in urban areas of Georgia, with potential reductions in racial and ethnic disparities.
