- Abstract
Introduction: The objective of this study is to evaluate severe maternal morbidity (SMM) of rural parturients delivering at rural compared to urban hospitals in the US., Methods: We identified patients aged 18-40 years in a multi-institutional claims database who lived in a rural ZIP code and delivered at a rural or urban hospital between October-December of 2015 and October-December of 2022. The primary outcome was SMM, and the secondary outcome was SMM exclusive of blood transfusions. We combined exact ZIP code matching and propensity score matching to compare SMM risk among patients living in the same rural community and delivering in urban as compared to rural hospitals., Results: A total of 214 296 patients from 571 ZIP codes were identified, including 47% delivering at rural facilities and 53% delivering at urban facilities. The SMM rate was 1.1% (0.3% excluding blood transfusions). After matching, urban versus rural delivery was associated with increased odds of SMM other than blood transfusion (odds ratio 2.44; 95% confidence interval 1.81-3.28), but was not associated with differences in risk of any SMM., Conclusion: There was no evidence of reduced SMM for rural patients delivering at an urban rather than a rural hospital. SMM exclusive of blood transfusions was increased for rural patients delivering at urban hospitals after matching on ZIP code and predictors of urban hospital delivery. Our findings undermine the assumption that delivery at a rural facility has inherently greater risks relative to delivery at an urban facility. As some health systems face challenges to maintain rural labor and delivery units, patient safety must be considered if confronted with the possibility of unit or hospital closures.
