School Attendance Following Receipt of Care From a School-Based Health Center.

Purpose: School-based health centers (SBHCs) may mitigate barriers to health care access and improve students' academic outcomes, but few studies test this hypothesis. We examined whether school attendance improved after students received care at an SBHC.

Methods: We conducted a secondary analysis of data from 17 SBHCs affiliated with a single large urban school district and demographic and attendance data from SBHC users (N = 14,030) and nonusers (N = 230,046) from August 2015-February 2020. We examined the percent of full school days present each month for three years before and after students' first SBHC visit and a proxy visit date for SBHC nonusers. Propensity weighted linear regression models tested whether visiting an SBHC was associated with a change in the attendance trajectory compared to a matched sample of SBHC nonusers.

Results: Among SBHC users, attendance trajectories declined more steeply prior to their first SBHC visit than after the first visit (preslope -0.71%, postslope -0.05%), whereas SBHC nonusers had a similar attendance trajectory over the entire period (preslope -0.18%, postslope -0.17%), with difference-in-difference 0.65. Changes in trajectories were more pronounced for students with a mental health encounter. Prior to the first SBHC mental health visit, SBHC users displayed a marked decline in monthly attendance (preslope -1.02%). After the first mental health visit, attendance increased (postslope 1.44%), with difference-in-difference 2.33.

Discussion: SBHC utilization was associated with improved school attendance over time, particularly for students with a mental health diagnosis. Investing in SBHCs may reduce school absenteeism and support student health.
