概要	OBJECTIVE:To clarify the relationship between the number of deliveries and maternal outcomes in Japan, considering the declining birth rate and the evidence that hospitals with few deliveries have medical safety issues.METHODS:Hospitalizations for deliveries were analyzed using the Diagnosis Procedure Combination database from April 2014 to March 2019, after which maternal comorbidities, maternal end-organ injury, medical treatment during hospitalization, and hemorrhage volume during delivery were compared. Hospitals were divided into four groups based on the number of deliveries per month.RESULTS:A total of 792 379 women were included in the analysis, among whom 35 152 (4.4%) received blood transfusions, with a median blood loss of 1450 mL during delivery. Regarding complications, pulmonary embolism was significantly more frequent in hospitals with the lowest number of deliveries.CONCLUSION:Using a Japanese administrative database, this study suggests an association between hospital case volume and the occurrence of preventable complications, such as pulmonary embolisms.
