Comparing the demand for blood in hospitals of Jahrom and standard blood transfusion indices

Abstract

Introduction: Due to the high costs of preparation and preservation of blood on the one hand, and the lack of a suitable model for blood preservation and utilization in Iranian hospitals, on the other hand, the current study was conducted to investigate the demand and the amount of blood utilization rate in different parts of hospitals in Jahrom and compare them with standard blood transfusion indices. Material and methods: In this descriptive cross-sectional study, 1066 patients were studied within 3 months for whom blood supply was requested in different wards of two hospitals in Jahrom. Patients' demographic data, hospitalization ward, blood group, hemoglobin, hematocrit, the number of requested and crossmatched blood units, the number of transfused blood units before and after surgery were collected. Statistical central tendency indices were determined by SPSS software and standard indices of blood transfusion including cross match/transfusion ratio (C/T), transfusion index (TI) and transfusion probability (TP) were calculated. Results: In the current study, of 1414 blood units requested, 10.18% of units were transfused to patients and only 19.38% of the cross-matched units were used. Blood transfusion indices C/T, TP and TI, were 5.15, 14.52 and 0.26, respectively, and the highest and lowest rates of C/T related to urology ward (18.18) and neonatal intensive care unit (0.1), respectively. Conclusion: Given the obtained blood transfusion indices, a significant number of cross-matched bloods are not used in the hospitals of Jahrom and for those surgeries in which cross-matched blood supply is needed; blood request should be based on the maximum surgical blood ordering schedule.
