Geographic access to care and pediatric surgical outcomes.

Introduction: Rurality and distance traveled for healthcare are associated with worse pediatric health indicators.

Methods: We retrospectively analyzed patients ages 0-21 at a quaternary pediatric surgical facility with a large rural catchment area between 1/1/2016-12/31/2020. Patient addresses were designated as metropolitan or non-metropolitan. 60- and 120-min driving rings from our institution were calculated. Logistic regression assessed the effect of rurality and distance traveled for care on postoperative mortality and serious adverse events (SAE).

Results: Among 56,655 patients, 84.3% were from metropolitan areas, 8.4% from non-metropolitan areas, and 7.3% could not be geocoded. 64% were within 60-min driving and 80% within 120-min. On univariable regression, patients living >120-min experienced 59% (95% CI: 1.09, 2.30) increased odds of mortality and 97% (95% CI: 1.84, 2.12) increased odds of SAE compared to those <60-min. Non-metropolitan patients experienced 38% (95% CI: 1.26, 1.52) increased odds of a serious postoperative event compared to metropolitan patients.

Discussion: Efforts to improve geographic access to pediatric care are needed to mitigate the impact of rurality and travel time on inequitable surgical outcomes.
