Analysis of Blood Inventory Levels and Availability in Clinical Practice: A Prospective Study
The aim of this study was to determine the extent of blood usage during blood transfusion procedures with evaluation of blood transfusion prescription practices in view of optimal and efficient utilization of blood transfusion services. We prospectively analyzed all the blood ordered between May, 2015 to April, 2017 from the blood bank of Hematology Laboratory in State Specialist Hospital, Akure, Ondo State Nigeria. The indices used were in compliance with the international blood transfusion clinical practice guidelines. Out of 1,536 blood units ordered and cross-matched in this study, 62.57% units were transfused to patients and 37.43% were not transfused. This indicates judicious blood usage during transfusion procedure to saving lives. The overall blood transfusion indices for Cross match to Transfusion ratio (C/T), Transfusion probability (%T) and Transfusion Index (TI) were 1.60, 62.57 and 1.00, respectively. This implied that blood at the point of utilization within the Hospital, enjoyed a favorable status of blood prescription practice compare to the standard reference values (that is; C/T Ratio≤2.5, %T≥30 and TI≥0.5) in most of the departments under study. Departments like Obstetrics and Gynaecology (CT=2.45, %T=25.45, TI=0.41) and General Theatre (C/T=3.8, %T=16.44, TI=0.26) exhibited inappropriate order of excessive cross-matched blood by junior medical officers which may be subsequently cancelled by senior colleagues on later review of the patients were common. This study showed a reliable and efficient clinical practice in the management of blood transfusion services from the point of order to the point of need which amount to a more appropriate, prudent and conserved utilization of blood products, resources and services.
