Tracking the Amount and Wastage Cost of Blood Components of Ospital ng Maynila Medical Center from January to December 2011 Through a Plotted Run Chart Base on the Monthly Crossmatched-to-Transfused Ratio per Department 6

ABSTRACT : In accordance with article 7719, otherwise known as the National Blood Services Act of 1994, Ospital ng Maynila Medical Center Blood Bank section has been converted to a transfusion facility that precludes recruiting and collecting blood from voluntary donors. This study is conducted to initiate an analysis using blood transfusion (BT) audit data from January to December 2011 as this is the start of well-established changes in blood transfusion practices due to the change in the blood bank section transfusion operation. The method used run chart as there is insufficient data for a control chart. The study is based on the computed monthly crossmatched - to - transfused (CT) ratio per department for the year 2011. The result showed a total overhead cost of P6801400 (P 6.8 M) for requested blood units with summary of 5810 units of blood requested comprising of 1659 whole blood (WB), 3518 packed red blood cells (PRBC),323 fresh frozen plasma (FFP), 306 platelet concentrate (PC) and 4 cryoprecipitate. Of these, 817 units or 14% of the total units procureed were unused, accounting for the P83420 total wastage cost of the hospital. The Departments of Obstetrics and Gynecology and Surgery has the most months of above their computed average wastage cost. The Opthalmology and Otorhinolaryngology Departments, although exhibiting the least amount of months of above average wastage cost, are nearlyat par with Obstetrics and Gynecology Department in terms of wastage and cost due to overestimated requests for blood units. Internal Medicine and Pediatrics Departments have the most cost-efficient results as rteflected by thier low CT ratios and low wastage costs, implying rational use of blood components. In conclusion, although at its initial stages, this study concurs with the cost-efficiency of rational blood use being propagated by the World Health Organization as evidenced by the results. The run chart method provides a viewpoint of blood utilization analogos to an expensive laboratory equipment : both have measurable process susceptible to outside changes : both exhibits patterns that can be tracked; and both have rooms for performance improvements. In this instance, polishing clinical guidelines regarding the practice of rational blood utilization and dispensation. 56
