Audit of pediatric transfusion practices in a tertiary care hospital.

OBJECTIVE: To perform a retrospective audit of transfusion practices, in order to study the appropriate and inappropriate usage of different blood components in pediatric population. METHODS: The present study, conducted over a period of 3 mo analyzed all the episodes of transfusions and divided them into appropriate and inappropriate according to the type of blood components, the requesting departments and the clinical indication of transfusion. Data was reviewed according to the British Committee for Standards in Hematology and American Association of Blood Bank guidelines. RESULTS: A total of 2,145 units of hemocomponents were transfused to children, including 1,181 units of red cell concentrates, 566 units of platelet concentrates/platelet rich plasma, 118 units of whole blood and 280 units of fresh frozen plasma in 1,819 episodes. Appropriate usage of blood components was 59.65%. Whole blood was most appropriately transfused (82.9%). Appropriate indications outnumbered inappropriate requisitions in Department of Pediatric Medicine (70.38 %), Nursery (82.54 %) and Thalassemia day care centre (55.63%). Red cell concentrate was most appropriately indicated in anemias (73.14%) and inappropriately in cases of surgeries (53.6%). Platelets were used more appropriately in all clinical indications. Whole blood was transfused most appropriately (100%) in double venous exchange therapy. Most appropriate indication of fresh frozen plasma usage was coagulopathy (42.57%). CONCLUSIONS: As the appropriate usage (59.65%) of blood components was low in the present study, regular auditing of transfusion practices from time to time is indicated. This not only helps guide their judicious use but also serves to evaluate and decrease their inappropriate usage.

Donor deferral characteristics for plateletpheresis at a tertiary care center in India- a retrospective analysis.

BACKGROUND: The demand for plateletpheresis is increasing day by day due to its many merits over random donor platelets. However, in our country, there is a dearth of apheresis donors due to greater devotion and time required for the procedure and lack of awareness. AIM: The aim of the present study is to analyse the reasons for deferral of apheresis donors at a tertiary care center. MATERIALS AND METHODS: This retrospective analysis was conducted to study the causes, frequency and the type of plateletpheresis donor deferral at regional blood transfusion center, Lady Hardinge Medical College and associated Shrimati Sucheta Kriplani Hospital and Kalawati Saran Childrens' Hospital. The study was undertaken over a period of two years (from January 2010 to December 2011. RESULTS: Out of a total of 343 donors screened, 87 donors were deferred, the overall deferral rate being 25.36%. The most frequent cause of deferral was a low platelet count accounting for 43.5% of all the causes followed by a low hemoglobin level (27.05%). Among the donors deferred for anaemia, 15 out of 23 (65.2%) had hemoglobin in the range of 11.5-12.4gm%, representing 17.2% of all deferrals. CONCLUSION: Based on these findings and the scarcity of apheresis donors in our country, we are of the opinion that the selection criteria for plateletpheresis donors should be revised to accommodate more donors and reduce deferral rate without compromising on the health of the donors.

Adverse reactions in whole blood donors: an Indian scenario.

BACKGROUND: Whole blood donation is generally considered to be a safe procedure, but occasionally adverse reactions of varying severity may occur during or at the end of the collection. The aim of the study was to estimate the frequency and type of adverse events occurring during blood donation and to assess the practices which would help to minimise them. MATERIALS AND METHODS: This retrospective single-centre study was conducted from June 2007 to November 2009 at a regional blood transfusion centre. All whole blood donations made at the centre were analysed. All adverse events occurring during or at the end of donation were noted using a standardised format. RESULTS: Overall 113 adverse events were reported in relation to 19,045 donations, resulting in an overall adverse event rate of 0.6%, that is, an incidence of 1 in every 166 donations. Presyncopal symptoms, in other words vasovagal reactions of mild intensity, were the most commonly observed adverse reactions and accounted for approximately 70% of all adverse reactions noted. CONCLUSIONS: Only 0.6% of blood donations were complicated by adverse events and most of these events were presyncopal symptoms. Our study reinforces the fact that blood donation is a very safe procedure which could be made even more event-free by following certain friendly, reassuring and tactful practices.
