Abstract
Fibrinogen concentrate (FC) for acquired hypofibrinogenemia associated with critical obstetrical hemorrhage (COH) was covered by public medical insurance in September 2021 in Japan. We aimed to investigate changes in the policy of FC use and its effect on COH after insurance coverage. A primary survey covering September 2020 to August 2021 and a secondary survey covering September 2021 to August 2022 were conducted at 428 higher-level medical facilities. We investigated the policy of FC use in transfusion strategy and the maternal outcomes in COH. Among the hospitals that responded to both surveys, the number of facilities that use FC increased from 51.5 (101/196) to 78.6% (154/196) (P < 0.0001). The number of COH cases treated using FC increased from 14.3 to 24.3% (P < 0.0001) and that transfused with ≥ 10 units of red blood cells (RBCs) decreased from 36.8 to 29.8% (P = 0.001). The incidence of pulmonary edema reduced by 3.7-2.0% (P = 0.021), and transfusion-induced allergy by 1.9-0.7% (P = 0.008). No changes were observed in the incidence of thromboembolism, arterial embolization, or hysterectomy. The increased use of FC after insurance coverage led to changes in the transfusion strategy, which may be associated with decreases in transfusions of RBCs, pulmonary edema, and transfusion-induced allergies.
