A prospective analysis of perioperative red blood cell transfusion practice in 110 patients undergoing elective primary total hip arthroplasty was conducted as a part of a quality assessment programme at the National Orthopaedic Hospital. In addition to demographic and clinical data, blood loss and perioperative transfusions were also recorded. Blood was collected for evaluation of haematocrit levels at predetermined intervals (preoperative and 6 h, 1, 2, 3, 7 days, postoperatively). ⋯ Using the criterion of discharge haematocrit of more than 36 per cent, 24 per cent of the patients were overtransfused. As compared to a previous retrospective analysis of blood transfusion in the same patient population which showed that inappropriate transfusion occurred in 45 per cent of the patients, the results from this study suggest a trend towards a more conservative transfusion practice. The improvement in transfusion practice may be due to the ongoing quality assurance programme and the use of transfusion guidelines.

Since the early 1980s the reports of infection and illness associated with Escherichia coli O157:H7 have increased dramatically worldwide, and particularly in the USA, Canada and UK. The spectrum of disease varies from asymptomatic carriage to haemorrhagic colitis and haemolytic uraemic syndrome (HUS). This infection is new to Ireland, and we report on 2 cases of isolation which outline the presentation of this organism with haemorrhagic colitis and HUS.

Spontaneous thoracic aortic dissection carries a high mortality despite progress in diagnosis and treatment. Early and accurate diagnosis is paramount and dependent on clinical and diagnostic imaging skills. A retrospective review of 55 consecutive patients referred with suspected thoracic aortic dissection to a medical cardiology department was performed. ⋯ At follow up 33 patients were alive. Clinical diagnosis of thoracic aortic dissection or aneurysm may be difficult. Frequently more than one imaging modality may be required in order to provide all of the necessary information for optimal patient management.

Survival and mortality outcomes for trauma patients admitted to Liverpool Hospital, Sydney were analysed to determine the adequacy of trauma care. TRISS and ASCOT survival probabilities and peer review were utilised to determine if deaths were avoidable. Evaluation methods were compared for assessment of care. ⋯ The Effectiveness (E) value for outcome was 0.91. Poor communication within the Area Trauma System was the greatest contributor to avoidable deaths. All trauma deaths need peer review rather than solely relying upon ASCOT and TRISS probabilities to identify "unexpected" deaths for detailed review.
