Background: Inventory of blood/blood components suffer due to outdating of Rh Negative units. Rationale of this article is strategy of transfusion of O Rh Negative red cells to all. A Rh Negative red cells can be given to A Rh Positive, AB Rh Positive. B Rh Negative red cells can be given to B Rh Positive, AB Rh Positive. AB Rh Negative red cells to AB Rh Positive recipients. AB Rh Negative FFP/PRP can be given to all. Objective was to avoid out dating of Rh Negatives by studying the percentage of outdated Rh Negative units amongst the all outdated.Methods: This was 9 years observational, retrospective, cross sectional and descriptive study conducted at tertiary care hospital. Outdated units of Rh Negative blood and components were analysed from the year wise discard registers of blood bank. Percentage of Rh Negative units within all outdated units were calculated.Results: 198 Rh Negative units of whole blood and blood components within all outdated units was 29.11%. Out of 198 the 20 Rh Negative blood components were discarded.Conclusions: Adopt type and screen protocol to prevent outdating. Avoid to bleed the rare blood groups. Audit by hospital transfusion committee and implementation of MSBOS. Track O Rh Negative red cells transfusion to Rh Positive as quality indicator. Track/review transfusion of O Rh negative red cells to Non O Rh negative recipients. Track AB Rh Negative FFP/PRP transfusions to all.

Introduction: Blood is a valuable resource & Ideally  in  a  good  set  up,  wastage  of  blood  and  blood products should never occur. But to maintain balance between demand and supply of blood and blood products blood banks have to keep adequate and satisfactory stock of blood all the time, still a very small amount of blood wasting in blood bank can occur. Aims & objectives: Present study was undertaken to analyse the causes of discarded whole blood units, discard rate and the measures to reduce number of discard in blood bank attached to tertiary care institute. Material and Methods: In present study yearly data of whole blood discarded units & yearly collection of 10 years from 2010-2019 was collected from the discard registers & yearly reports of blood bank, govt. medical college, akola and analysed. Results & Conclusion: It has been found that out of total 77514 whole blood units which were collected, 2276 (2.93%) whole blood units were discarded. Of the total discarded whole blood units, 966 (42.44%) were discarded due to seropositivity for TTI, 801 (35.19%) due to insufficient quantity, 378 (16.61%) due to expiry, 112 (4.92%) due to other causes & 19 whole blood units were hemolysed. Blood stock and quality management system, Trained, dedicated & adequate staff, properly functioning blood transfusion committee to monitor activities of blood transfusion service and timely implementation of guidelines are the pre-requisites to provide safe and effective blood and to minimize discard of blood.
