ObjectiveTo determine the clinical use and associated costs of routine postoperative hematocrit after elective gynecologic surgery.MethodsWe reviewed the charts of all women who had elective gynecologic surgery over 12 months at a community hospital. Demographic data, estimated blood loss at surgery, pre- and postoperative hematocrits, postoperative symptoms suggesting anemia, and incidence of transfusion were tabulated. Laboratory charges for hematocrit at the hospital were used to develop an economic assessment. Statistical analysis was done with Student t test, Mann-Whitney U test, and Fisher exact test.ResultsAmong 1105 women who had elective surgery, a single postoperative hematocrit was done in 761 (69%) and two or more postoperative hematocrits (mean 2.4, range 2-6) were done in 201 (18%). The overall incidence of blood transfusion related to elective gynecologic surgery was 1.9% (21 of 1105). Five of those women needed preoperative transfusions, eight needed intraoperative transfusions, and the remaining eight had postoperative transfusions. All women who needed postoperative transfusion showed some sign or symptom of anemia. None received transfusions based solely on hematocrit. Risk factors for postoperative transfusion included low preoperative hematocrit and increased intraoperative blood loss.ConclusionRoutine postoperative hematocrit in asymptomatic women after uncomplicated elective gynecologic surgery did not improve outcome.
