Examining outpatient occupational therapy utilization among children and youth with special health care needs in South Carolina: A structural equation model of individual- and community-level factors.

BACKGROUND

Children and youth with special health care needs (CYSHCN) comprise 23 % of the pediatric population in South Carolina (SC), compared to state prevalences of 13.6 %-24 % nationwide. While occupational therapy (OT) is critical to maximizing CYSHCN's participation in daily activities, there are significant disparities in rehabilitation access in the Southeast region.

OBJECTIVE

This study examines associations between patient-and community-level factors and outpatient OT utilization.

METHODS

This study analyzes OT utilization data among CYSHCN (N = 1913) in a health system in SC from 07/01/2022-06/31/2023, merged with Child Opportunity Index 2.0 zip-code level social drivers of health (SDOH) data. SDOH are non-medical factors that affect individual's long-term health, with estimates ranging from "very low" to "very high" opportunity. Structural equation modeling was conducted to understand complex associations between observed and latent variables in a real-world context.

RESULTS

CYSHCN were diagnosed with congenital (40.77 %), developmental (37.87 %), and neurological/neuromuscular conditions (21.36 %). CYSHCN who were non-Hispanic Black or Hispanic and were hospitalized were associated with living in lower opportunity areas. CYSHCN with private or military/other insurance/self-pay were associated with living in higher opportunity areas than Medicaid-insured CYSHCN. CYSHCN who were female and ≥12 years demonstrated lower OT utilization. CYSHCN who participated in speech and/or physical therapy demonstrated higher OT utilization. OT utilization increased with each increase in SDOH.

CONCLUSION

With these findings, healthcare providers may consider accessibility barriers, including transportation, when referring CYSHCN to OT services. Further research is needed to examine the impact of household-level SDOH on OT access across SC.
