Primary Care Enhanced Access Services and the Association With Nonurgent Pediatric Emergency Department Utilization and Child Opportunity Index.

Objectives: This study aims to examine the association between primary care practice characteristics (enhanced access services) and practice-level rates of nonurgent emergency department (ED) visits using ED and practice-level data. Survey data suggest that enhanced access services within a child's primary care practice may be associated with reduced nonurgent ED visits.

Methods: We performed a cross-sectional analysis of nonurgent ED visits to a tertiary pediatric hospital in Western Pennsylvania with nearly 85,000 annual ED visits. We obtained patient encounter data of all nonurgent pediatric ED (PED) visits between January 2018 and December 2019. We identified the primary care provider at the time of the study period. For each of the 42 included offices, we determined the number of unique children in the office with a nonurgent PED visit, allowing us to determine the percentage of children in the practice with such a visit during the study period. We then stratified the 42 offices into low, intermediate, and high tertiles of nonurgent PED use. Using Kruskal-Wallis tests, logistic regression, and Pearson χ 2 tests, we compared practice characteristics, enhanced access services, practice location Child Opportunity Index 2.0, and PED visit diagnoses across tertiles.

Results: We examined 52,459 nonurgent PED encounters by 33,209 unique patients across 42 outpatient offices. Primary care practices in the lowest ED visit tertile were more likely to have 4 or more evenings with office hours (36% vs 14%, P = 0.04), 4 or more evenings of weekday extended hours (43% vs 14%, P = 0.05), and at least 1 day of any weekend hours (86% vs 29%, P = 0.01), compared with practices in other tertiles. High PED use tertile offices were also associated with lower Child Opportunity Index scores.

Conclusions: Primary care offices with higher nonurgent PED utilization had fewer enhanced access services and were located in neighborhood with fewer child-focused resources.
