Maximum Surgical Blood Order Schedule (MSBOS) for Cardio - Thoracic & Vascular Interventions in an Apex Tertiary Care Hospital of India

Background: Since the time of use of blood and blood products in medical and surgical interventions, its utilization is a point of debate. Over demanding of blood from blood bank services may lead to aging of blood and wastage of blood units. It also negatively impacts on the services of blood bank. There are various indices to estimate the utilization of blood services in a healthcare institute. Methods: In this study we have analysed 4 months blood bank data for CTVS interventions. Total 252 patients were involved. We have analysed the utilization of PRBC for the cardiac surgeries. Also, we have formulated MSBOS from the available data. Results: Results of this study shows, total 1006 units of PRBC were demanded for the surgeries, 784 units were issued by the blood - bank of the hospital and out of which 60 % (472 units) were transfused to the patients. C/T ratio was less than 2.5 in majority of the surgeries, T% was more than 30% in all the cases, and TI was greater than 0.5 in all surgeries. These figures show the significant requirement of blood in cardiac surgeries. Further, there was optimal utilization of blood in the institute.
