Therefore, there is a need to continuously monitor blood utilization and audit the transfusion practices to identify key areas of concern for blood usage. The aim of this study was to analyze the number of the requests for, transfusion and the wastage of blood and blood components based on the ratio of the number of cross-matched blood to transfusion (C/T) in Semnan hospitals. Materials and Methods In this cross sectional descriptive study, a total of 6749 order forms for blood and blood components, which have been sent to the blood banks of Semnan hospitals within September 2015 to September 2016, were evaluated. The collected data from the blood banks were analyzed using SPSS 16 Software. The mean+SD of the numerical variables and the absolute and relative frequencies of the rasteh (categorical) variable according to the subgroups under study were reported. Results In this study, out of 6749 blood order forms, 14296 units of blood products including red blood cells, FFP and platelet had been ordered. The total cross-match to transfusion ratios (C/T ratio) were 1.37, 1.77 and 1.34 respectively in Amir, Cowsar and Shafa Hospitals with the RBC request rates forming 24.9%, 58.8%, and 16.4% of the total requests in the same order. Conclusions The results show that blood consumption in Semnan hospitals is appropriate as compared with the international standards. Blood utilization model in some wards like internal, ICU and emergency were not appropriate, indicating that a more effective guideline for blood order is required. M3 ER -
