A 15-year study of the changing demographics and infection risk in a new UK cardiac surgery unit.

Objectives: National trends in cardiac surgery show a shift towards a higher preoperative risk profile and factors that might also be expected to increase the risk of postoperative infective complications. We document the changing patient demographics in the first 15 years of a new cardiac surgery unit and examine the impact of these and other changes in estate, staffing and clinical protocols, on the risks of common postoperative infections.

Methods: Data recorded included patient age, sex and body mass index, type and number of operations, logistic EuroSCORE, mortality rate, urgency of operation, reoperation rate, requirement for intra-aortic balloon pump, incidence of diabetes and the incidence of common postoperative infections.

The performance of three estimates of glomerular filtration rate before and after live donor nephrectomy.

Serum creatinine-based estimates of glomerular filtration rate (GFR) are inaccurate in healthy individuals. Therefore, their use in assessment prior to live donor nephrectomy has been restricted. There are less data on their use postdonor nephrectomy.
