Abstract
The effect of an educational program designed to address misconceptions about the perioperative transfusion of fresh-frozen plasma (FFP) was examined. Results of a baseline audit of FFP use were compared to those of a study subsequent to the educational process. Statistical analysis of the data revealed that the decrease in the number of patients transfused with FFP, from 32 of 2077 operative cases in Group A (baseline) to 18 of 2540 operative cases in Group B (after education), was significant (p < 0.01). Analysis of the justifications given for transfusion of FFP revealed that the increase in acceptable indications from 47 percent in Group A to 78 percent in Group B was also significant (p < 0.05). There was no significant difference between the two groups in units of FFP transfused per patient (Group A, 3.66 .+-. 3.2, vs. Group B, 2.47 .+-. 1.7) or red cells (Group A, 2.84 .+-. 5.2, vs. Group B, 5.22 .+-. 4.4), and the patterns of platelet transfusion were similar in the two groups. There was a significant difference in the postoperative partial thromboplastin time (Group A, 38.2 .+-. 8.7 vs. Group B, 56.3 .+-. 24 seconds, p < 0.01) but no significant difference in postoperative prothrombin time (Group A, 14.1 .+-. 2.6 vs. Group B, 15.4 .+-. 3.3 seconds). It can be concluded that an educational program designed to address misconceptions in transfusion practice can alter physician performance and thereby reduce the inappropriate use of FFP.
