Background Blood transfusion services are crucial for modern medical care, particularly for surgical interventions, chronic diseases, pregnancy complications, and malignancies. There is an increasing demand for blood products in India; hence, optimizing resource utilization in blood banks is essential. This study aims to evaluate the crossmatch-to-transfusion (C/T) ratio as a tool for analyzing and optimizing the utilization of blood bank resources. The C/T ratio of the various clinical departments will also identify inefficiencies in blood ordering practice and plan corrective actions. Methods A retrospective observational study was conducted at the Blood Center of Saveetha Medical College and Research Center. Data were collected over a three-month period from November 1, 2023, to January 31, 2024. Information was collected from crossmatch request forms, crossmatch registers, issue registers, and digital medical records. The study included all crossmatch requests received within the study period. The C/T ratio was calculated department-wise, and the departments with high C/T ratios were identified. Results In the study, 1,861 packed red blood cell (RBC) units were crossmatched, of which 797 units were issued. The overall hospital C/T ratio was 2.33, which indicates excessive blood ordering. The Department of Obstetrics and Gynaecology had the highest C/T ratio of 5.14, followed by Oncology (3.09), Urology (2.9), General Surgery (2.26), and Orthopaedics (2.08). These high ratios showed significant overordering and underutilization of crossmatched blood units. Conclusion This study revealed that the C/T ratio in the hospital exceeded international standards, especially among surgical departments. This indicates a need for optimizing blood ordering practices to reduce unnecessary crossmatches, minimize wastage, and enhance resource management. Implementing strategies to correct the high C/T ratio and regular auditing can improve blood transfusion services and ensure efficient utilization of blood products.
