An audit of error rates in a UK district hospital transfusion laboratory.
We have audited the error rates of our transfusion laboratory and compared these with error rates reported in the transfusion literature. Error rates were calculated using workload data from the department. The majority of errors that were detected were preanalytical and related to inadequate or incomplete data provided on the sample or request form. These errors were all corrected prior to any further action being taken on that request. The main analytical errors were transcription errors in entering patient identification information into the laboratory computer by transfusion staff together with the incorrect performance of blood group testing. For postanalytical errors the main errors were failure of nursing staff to follow procedures for the collection of blood components prior to transfusion. There were no serious consequences identified of the errors detected in this study. It was difficult to compare these results with those published in the literature in view of the different methodologies that have been reported when error rates have been determined. A standard method should be developed in the UK for calculating error rates so that laboratories can benchmark their performance against comparable organizations.
