UK and international guidelines for autologous blood transfusion state that autologous blood should be clearly labelled with the patient's details to ensure the safety of the technique. Despite these guidelines, routine labelling of autologous blood from techniques such as Intra and Postoperative Cell Salvage (ICS and PCS) is not standard practice in the UK. A recent report to Serious Hazards of Transfusion (SHOT) of wrong blood, wrong patient involving unlabelled PCS blood reinforces the need for labelling of autologous blood. To address this issue, in 2008, the UK Cell Salvage Action Group (UKCSAG) piloted an autologous transfusion label with the intention that it would be rolled out throughout the UK for use with all autologous transfusion procedures. The pilot labels were available to all UK hospitals using ICS through the machine manufacturers. Towards the end of the pilot phase, the labels were also made available to a selected number of hospitals for use in PCS through the PCS equipment manufacturers. Following the pilot, a feedback questionnaire was sent out to hospitals via the UKCSAG contacts network. Hospitals were asked to provide feedback that would inform a review of the label before national roll out. Feedback related to ease of use, problems they had experienced, how well the label fulfilled their organisational requirements and if there were any specific changes they would like to see included in the reviewed label. If hospitals had not used the pilot label, the questionnaire asked them to feedback the reason why. Once the feedback had been collated the review of the label was completed, accommodating the feedback where appropriate, and addressing problems that had arisen with the label. Where conflicting feedback was received from two or more hospitals, a final decision was made by the UKCSAG based on their experience and expertise in this area. The reviewed label was signed off by the UKCSAG before consultation with manufactures of both ICS and PCS equipment with regard to their willingness to support the purchase and distribution of the labels to their customers. The label has been available in the UK since January 2011.
