Hutcheon JA, et al. - Researchers investigated the extent to which hospitals vary in the use of obstetrical blood transfusion via performing a population‐based cohort study linking provincial perinatal and blood transfusion registries in British Columbia, Canada, 2004‐2015. Assessment of all pregnant women delivering at or beyond 20 weeks’ gestation at any British Columbia hospital was done. Across the study period, crude institutional transfusion rates varied from 3.7 to 23.6 per 1,000 among the 44 hospitals, with an average of 8.3 per 1,000. Following adjustment for maternal characteristics, institution, and delivery risk factors, there remained a nearly 3‐fold difference in rates between the 10th and 90th percentile (5.4 to 14.5 per 1000). As differences in patient case‐mix or institutional factors did not explain meaningful variation between hospitals in use of blood transfusion during pregnancy, it seemed that over‐ or under‐utilization of this resource may be occurring in obstetrical care.
