BACKGROUND: Pregnancy-related @entity1211 ( @entity1211 ) is a major cause of maternal morbidity and mortality. A new risk assessment model for @entity1211 in relation to pregnancy has been introduced in Sweden. We wished to determine the proportion of preventable @entity1211 cases if the model had been in use and make a brief cost-benefit analysis. METHODS: A hospital-based retrospective case-control study of all postpartum @entity1031 instances of @entity1150 and @entity1151 during a 16-year period. Large anamnestic risk factors at the time of delivery were assessed. We correlated the findings with the new Swedish guidelines for thromboprophylaxis. RESULTS: We found 37 cases of postpartum @entity1211 during the study period. Nineteen of all @entity1211 cases (51%) and eight out of eleven of cases of @entity1151 (73%) had two or more large anamnestic risk factors, ie, they would have been subjected to thromboprophylaxis if the new guidelines had been used. The cost of each preventable @entity1211 was lower than treating a @entity1211 . CONCLUSION: Approximately one-half of postpartum @entity1211 cases and 70% of @entity1151 cases have at least two large risk factors and might be preventable using the new algorithm. From the perspective of the health care system the new recommendations appears to be cost-effective.

Postpartum XXXX : severe events might be preventable using a new risk score model.
