Abstract
OBJECTIVE: To survey the attitudes of gynecologic oncologists about indications for blood transfusion, and compare them to current recommendations about transfusion practice. METHODS: With the permission of the Society of Gynecologic Oncologists (SGO), a study questionnaire was mailed to 548 members and candidates in their directory. The questions asked about transfusion threshold before chemotherapy, following ovarian debulking, and after endometriosis surgery. Indications for transfusion were assessed using a qualitative/quantitative scale. Responses were analyzed with respect to years of SGO membership and practice setting using the chi 2 test and analysis of variance. Results were compared to the 1992 guidelines for transfusion of the American College of Physicians (ACP). RESULTS: Two hundred eighty-five forms were returned (52% of total). Fifty-one percent of respondents were in full-time academic positions; 36% were in private practice. Sixty-one percent were full SGO members, and 35% were candidates. The average prechemotherapy transfusion threshold (TT) was a hemoglobin concentration (hgb) of 7.9 +/- 0.7 g/dl (g). At that level the mean transfusion was 1.9 +/- 0.5 units of packed red blood cells (U). For the ovarian debulking scenario, the mean postoperative TT was 8.1 +/- 0.8 g with a mean transfusion of 1.9 +/- 0.4 U. For the endometriosis case, the mean TT was 7.0 +/- 0.8 g, with a mean transfusion of 1.9 +/- 0.5 U. Analysis showed no difference in practice based on years of SGO membership or practice setting. CONCLUSION: A majority of the gynecologic oncologists surveyed offers transfusion at levels of anemia similar to ACP recommendations, but frequently transfuse more units than recommended. A substantial minority does not follow the guidelines at all.
