| Abstract: | Introduction Research has shown good outcomes among individual low‐risk women who receive perinatal care from midwives, yet little is known about how hospital‐level variation in midwifery care relates to procedure use and maternal health. This study aimed to document the association between the hospital‐level proportion of midwife‐attended births and obstetric procedure utilization. Methods This analysis used 2 data sources: Healthcare Cost and Utilization Project State Inpatient Database data for New York in 2014, and New York State Department of Health data on the percentage of midwife‐attended births at hospitals in the state in 2014. Using logistic regression, we estimated the association between the hospital‐level percentage of midwife‐attended births and 4 outcomes among low‐risk women: labor induction, cesarean birth, episiotomy, and severe maternal morbidity. Results Hospital‐level percentage of midwife‐attended births was not associated with reduced odds of labor induction or severe maternal morbidity. Women who gave births at hospitals with more midwife‐attended births had lower odds of giving birth by cesarean (eg, adjusted odds ratio aOR], 0.70; 95% confidence interval CI], 0.59‐0.82 at a hospital with 15% to 40% of births attended by midwives, compared to no midwife‐attended births) and lower odds of episiotomy (eg, aOR, 0.41; 95% CI, 0.23‐0.74 at a hospital with more than 40% of births attended by midwives, compared to no midwife‐attended births). Discussion Our results indicate that hospitals with more midwife‐attended births have lower utilization of some obstetric procedures among low‐risk women; this raises the possibility of improving value in maternity care through greater access to midwifery care. |
