Clinical impact of massive transfusion protocol implementation in non-traumatic patients

Abstract Background Massive transfusion protocol (MTP) has been used to provide plasma and packed red blood cells (pRBCs) rapidly. MTP also has been adapted for non-traumatic patients. The effects of hospital-wide MTP implementation on clinical outcomes were reviewed. Methods This was a retrospective study of patients who received massive transfusion before and after MTP implementation, between August 2010 and May 2018. Massive transfusion was defined as 10 or more units of pRBCs within 24 hours. Recipients of massive transfusion were divided into periods before and after MTP implementation. The 24 -h death rate, thirty-day death rate and several laboratory findings were investigated. Results Eighty patients whose massive transfusion occurred before MTP implementation and 63 patients whose massive transfusion occurred after MTP implementation were compared. No statistically significant difference was found in 24 -h death rate (15.0% vs. 23.8%, p = 0.181), or 30-day death rate (43.8% vs. 36.5%, p = 0.381). Use of an anti-fibrinolytic agent was more frequent in patients after the MTP implementation (31.3% vs. 55.6%, p = 0.003). A statistically significant difference was found in the lowest body temperature of the two groups during the 24 -h period (34.7 °C vs. 35.6 °C, p  Conclusions MTP implementation showed improved coagulation profiles, but did not show a statistically significant death-rate reduction in non-traumatic patients.
