An evaluation of efficient blood supply of Blood Bank, Police General Hospital

Abstract

Background: Since Police General Hospital is 600 bed sized, blood bank staffs have been interested in setting blood inventory levels to be reserved for patient. The objectives of this study are to evaluate the efficiency of blood reserve whether it is meet the level as set or not and to evaluate whether the blood level as set is proper to the actual patient needs or not.

Methods: A perspective study of efficient blood inventory levels has been studied on the data collected at Police General Hospital for 4 months periods (July to October 2009) comprising of stock of packed red blood cell (PBC), expire rate of red cell units for both pre and post setting the blood level - and number of patients who were postponed from the operation caused by insufficiency of blood reserve. Then analyze by statistical software, SPSS.

Results: The assessments of the data collected for four month period during July to October 2009 are that the blood bank can reserve the PBC for each blood group averagely with 67.4% above the target (≥ 60%), no patient was postponed caused by the insufficiency of blood reserve., the expired rate of PBC before setting the blood inventory levels was approximately 0.77-4.02%. (4.02 % in January and the expired rate of PBC after setting the blood inventory levels was approximately 0.64-3.7%. (July and September had a high expired rate 3.7% and 3.6% respectively). So the expired rate of PBC in each month is under the setting level (< 5%) and meets the objective.

Conclusions: From the assessment, it’s found that the efficiency of blood reserve was 67.4% which is above the target the blood inventory levels were proper at present. However, the blood usage may be changed in the future, the optimal of blood inventory levels should be evaluated periodically and need to be adjusted for the most effectiveness of blood utilization management.
