| Sumario: | Introduction: Blood reservation in surgical operations should be based on a standard protocol. Considering the existing challenges in the appropriate use of blood products and the importance of monitoring blood transfusion complications, this study was conducted to evaluate the efficacy and complications associated with blood product transfusions in Jahrom hospitals. Materials and Methods: In this cross-sectional study, 3,400 blood request forms from Paymanieh and Shahid Motahari hospitals in Jahrom were reviewed during 2024. Using the extracted data, the amount of blood products used, the crossmatch-to-transfusion ratio (C/T), and the complications related to blood transfusion were determined. The data were analyzed using SPSS-26, t-test, and ANOVA. Results: Out of 3400 blood requests, crossmatch was performed for 1951 patients (57.3 %), and 728 patients (31.1 %) received products (1228 units). The percentage of requested packed cell products was 58.9%, and the overall C/T ratio was 4.16, a transfusion index (TI) of 0.63, and a transfusion probability (T%) of 41.4%. The highest C/T ratios were observed in oncology (7.2) and obstetrics-gynecology (6.1) departments. Acute complications related to product transfusion occurred in 28 patients (3.9%). A significant association was observed between Male physicians and complications (P<0.004). Conclusions: The present study indicates unnecessary transfusion demands and the occurrence of adverse complications, specifically in oncology and obstetrics-gynecology departments. These findings emphasize the need for a review of existing protocols, an emphasis on implementing the local MSBOS program, and continuous training of personnel to enhance the quality of blood transfusion services.
