N2 - OBJECTIVE: To assess the prevalence and risk factors of emergency peripartum hysterectomy.DESIGN: Nordic collaborative study.POPULATION: 605 362 deliveries across the five Nordic countries.METHODS: We collected data prospectively from patients undergoing emergency peripartum hysterectomy within 7 days of delivery from medical birth registers and hospital discharge registers. Control populations consisted of all other women delivering on the same units during the same time period.MAIN OUTCOME MEASURES: Emergency peripartum hysterectomy rate.RESULTS: The total number of emergency peripartum hysterectomies reached 211, yielding an incidence rate of 3.5/10 000 (95% confidence interval 3.0-4.0) births. Finland had the highest prevalence (5.1) and Norway the lowest (2.9). Primary indications included an abnormally invasive placenta (n = 91, 43.1%), atonic bleeding (n = 69, 32.7%), uterine rupture (n = 31, 14.7%), other bleeding disorders (n = 12, 5.7%), and other indications (n = 8, 3.8%). The delivery mode was cesarean section in nearly 80% of cases. Previous cesarean section was reported in 45% of women. Both preterm and post-term birth increased the risk for emergency peripartum hysterectomy. The number of stillbirths was substantially high (70/1000), but the case fatality rate stood at 0.47% (one death, maternal mortality rate 0.17/100 000 deliveries).CONCLUSIONS: A combination of prospective data collected from clinicians and information gathered from register-based databases can yield valuable data, improving the registration accuracy for rare, near-miss cases. However, proper and uniform clinical guidelines for the use of well-defined international diagnostic codes are still needed.
