ABSTRACT The National Haemovigilance Office has collected and analysed reports on errors associated with transfusion since 2000. A 3-year pilot research project in near-miss event reporting commenced in November 2002.
Near-miss reports from 10 hospital sites were analysed between May 2003 and May 2005. The Medical Event Reporting System for Transfusion Medicine was used to collect and analyse the data. Root cause analysis was used to identify causes of error.
A total of 759 near-miss events were reported. Near misses are occurring 18 times more frequently than adverse events causing harm. Sample collection was found to be the highest risk step in the work process and was the first site of error in 468 (62%) events. Of these, 13 (3%) involved samples taken from the wrong patient. Medical staff were frequently involved in error. The general wards and emergency department were identified as high-risk clinical areas, in addition, 78 (10%) events occurred within the transfusion laboratory. Three specific human and two system failures were shown to have been associated with the errors identified in this study.
This study confirms that near-miss events occur far more frequently than adverse events causing harm. Collecting near-miss data is an effective means of highlighting human and system failures associated with transfusion that may otherwise go unnoticed. These data can be used to identify areas where resources need to be targeted in order to prevent future harm to patients, improving the overall safety of transfusion.

    ABSTRACT: Pre-transfusion testing includes proper requisitions, compatibility testing and pre-release checks. Proper labelling of samples and blood units and accurate patient details check helps to minimize the risk of errors in transfusion. This study was aimed to identify requisition errors before compatibility testing. The study was conducted in the blood bank of a tertiary care hospital in north India over a period of 3 months. The requisitions were screened at the reception counter and inside the pre-transfusion testing laboratory for errors. This included checking the Central Registration number (C.R. No.) and name of patient on the requisition form and the sample label; appropriateness of sample container and sample label; incomplete requisitions; blood group discrepancy. Out of the 17,148 blood requisitions, 474 (2.76 %) requisition errors were detected before the compatibility testing. There were 192 (1.11 %) requisitions where the C.R. No. on the form and the sample were not tallying and in 70 (0.40 %) requisitions patient’s name on the requisition form and the sample were different. Highest number of requisitions errors were observed in those received from the Emergency and Trauma services (27.38 %) followed by Medical wards (15.82 %) and the lowest number (3.16 %) of requisition errors were observed from Hematology and Oncology wards. C.R. No. error was the most common error observed in our study. Thus a careful check of the blood requisitions at the blood bank reception counter helps in identifying the potential transfusion errors.

    ABSTRACT: To describe the effect of interventions designed to improve patient identification (PI) during pathology collection in the ED. A prospective before-and-after intervention study was conducted between June 2009 and June 2010 in a regional ED in Queensland, Australia. Interventions aimed to improve PI and specimen labelling, and consisted of: (i) education alone; and (ii) education plus an armband scanner that voice-prompted collector behaviour. Main outcomes measured included: frequency of correct key behaviours (KBs) during specimen collection, pathology integrity errors and cost of interventions. Data from 282 ED pathology collections were analysed (before: n = 115, after with education: n = 95, after with education plus armband scanner: n = 72). KBs for PI and labelling improved significantly following education plus armband scanner use. Application of armbands before sample collection increased (36% vs 90%, P < 0.001), as did asking the patient to state their name (25% vs 93%, P < 0.001) and date of birth (22% vs 93%, P < 0.001). These results were similar, albeit less pronounced, when the effect of education only was assessed. No primary patient misidentification was detected in this small study. The annual costs for a hospital to adopt the education programme with and without the armband scanner were $104 045 and $5330 respectively. ED staff had poor behaviours for identifying patients and labelling pathology specimens before intervention. These safety behaviours were considered an assumed skill. Education alone improved critical KBs markedly that was further augmented by the armband scanner. The cost to adopt education alone is relatively low compared to the addition of armband scanner technology. © 2015 The Authors.

    ABSTRACT: A near-miss event is defined as an event that could have resulted in an injury, fatality, or property damage if it had not been prevented. Analysis of near-miss events could be an efficient method in the study of adverse events. Reporting of near-misses has many benefits in the study of adverse events since near-misses occur more frequently than adverse events. In addition, as they have no consequences, fear that the professionals involved would have to report them is less. However, up to now, this method has been slow to develop. We present two clinical cases that help to understand the usefulness of the near-miss reporting system.
