In the comparison of transfusion in all included patients, we found that the traditional doctor experience-based transfusion strategy subject to blood transfusion guidelines appeared to be not completely consistent with the requirements of "guidelines" in the perioperative RBC transfusion.
Reason analysis: The control group was given RBC transfusion not completely according to the regulation of blood transfusion guidelines. Some patients needing RBC transfusion fail to strictly perform certain rule.
There were no patients of POTTS-E group that were not transfused with Hb <7 g/dl or were transfused with Hb >10 g/dl; 5 patients of CON group were not transfused with Hb <7 g/dl and 1 case was still transfused with Hb >10 g/dl; POTTS-E group was totally (100%) conformed to the requirements of the transfusion guideline to RBC infusion, which was higher than that of CON group (81.25%) [Table 5].{Table 5}
They were asked if the coagulation tests were completed within 24 hours before transfusion and how long after transfusion those tests were repeated, if additional transfusion was requested before completion of posttransfusion coagulation tests, and whether transfusion met the institution's transfusion guidelines. Five laboratory-specific performance indicators were calculated from the study results, specifically: (1) rate of plasma transfusions that met institutional guidelines; (2) rate of pretransfusion coagulation testing; (3) rate of posttransfusion coagulation testing; (4) plasma utilization rate; and (5) rate of reported transfusion reactions.
Participating institutions were asked to complete a questionnaire with 14 additional questions related to plasma transfusion guidelines, compliance monitoring and reporting, number of plasma units transfused in the previous year, plasma wastage rate, massive transfusion protocols, and serious plasma-related transfusion reactions.
Higher rates of pretransfusion coagulation testing tended to occur in institutions that used AABB as a source for developing transfusion guidelines, and lower rates of posttransfusion coagulation testing tended to occur in institutions with the following characteristics: (1) rural location; or (2) where the blood bank supervisor or manager was involved in the development of transfusion guidelines.
Participants were asked about plasma transfusion guidelines at their institutions.
Compliance with institutional plasma transfusion guidelines was monitored in all but 9 (10.6%) of the institutions, and 15 (17.6%) did not report the results of their monitoring to any quality or utilization committee.
Use of coagulation test results, development and compliance with plasma transfusion guidelines, and review of plasma transfusion practices were evaluated, as were plasma wastage and history of recent severe plasma-related transfusion reactions.
