SummaryThe importance and variability of pre-operative anaemia in cardiac surgical patients across the UK is not known, and there is debate about its association with patient outcomes. The Association of Cardiothoracic Anaesthetists carried out its first national audit on anaemia and transfusion, and analysed data from 19,033 patients operated on in 12 cardiac surgical centres between 2010 and 2012; 5895 (31%) had pre-operative anaemia. Centre-specific prevalence of anaemia varied from 23% to 45%; anaemia was associated with older patients, diabetes and surgical risk (Euro-SCORE). Nevertheless, controlling for these factors, regional variation remained an independent effect (p < 0.001). Multivariable analysis demonstrated an independent association of anaemia with transfusion (odds ratio (95% confidence interval) 2.75 (2.55-2.95), p < 0.001), mortality (1.42 (1.18-1.71), p < 0.001) and hospital stay (geometric mean ratio (95% confidence interval) 1.15 (1.13-1.17), p < 0.001). Haemoglobin concentration per se was also independently associated with worse outcomes; a 10 g.l À1 decrease in haemoglobin was associated with a 43% increase (95% confidence interval 40-46%) in the odds of transfusion and a 16% increase (95% confidence interval 10-
The incidence of clinically significant neoplasia on endoscopic follow-up after the nonoperative management of acute diverticulitis is 9.2%. Those with complicated diverticulitis are at higher risk, whereas the incidence of clinically significant neoplasia in those with uncomplicated diverticulitis is equal to the incidence in average-risk individuals. Routine diagnostic colonoscopy following the nonoperative management of acute uncomplicated diverticulitis may not be warranted.
A significant increase in the use of neoadjuvant chemotherapy over time was identified, and treatment with mastectomy as definitive surgical management remained high. There was significant variability in neoadjuvant chemotherapy use by the operating surgeons, in addition to factors generally associated with more locally advanced/aggressive tumors.
Infants requiring PR have significantly higher mortality and suffer greater morbidity than those undergoing NPR. This association is independent of other known predictors of mortality. Identifying prenatal features associated with this high risk group would be of great clinical value.
