Background: Blood shortages caused by influenza epidemics may be a major challenge for hospital transfusion services. Available national blood contingency plans outlining guidelines for handling the shortage at national levels. Management of shortage at hospitals is a complicated clinical procedure and requires a well planned approach for the reduction of blood utilization.
Design: This study is designed to assess the most important blood utilization variables at regional level to develop a factor for ranking clinical services for utilization management purposes. Annual blood utilization data for Calgary health region (April 2007-March 2008) was collected. Blood utilization indices and variables including red cell utilization (RCU/Total%), risk of transfusion (transfusion index), number of patients/service%, daily red cells used/day and ratio of elective/non-elective patients for each clinical service were determined. Basic regional transfusion data including the above variables were introduced to a semi-empirical-mathematical soft ware to integrate the utilization variables within a single formula. The outcome is a specific number called blood contingency factor (BCF) used to rank the clinical services to warrant efficient and safe blood saving.
Results: Clinical services were ranked based on their BCF as follows; chronically transfused outpatients (68), cardiac surgery (39), vascular surgery (21), orthopaedic surgery (10), hematology-oncology (7) and general surgery (6). The ranking is used to develop a blood utilization module for management of blood shortage. The final plan is shared with clinical services and endorsed by regional transfusion committee.
Conclusions: The Integration of BCF into the regional blood utilization contingency plan seems provides a safe, efficient, multitier and practical plan with relatively acceptable accuracy. Since the regional data is collected from a metropolitan area with comprehensive medical services, it is suggested that BCF may create similar outcomes in tertiary hospitals.
