*Post-operative adverse events (PAE)*

*3.5 The rate of PAEs 7 within 30 days was significantly higher at Harefield than other UK centres: 67.2% (95% CI 53.7%-79%) for the whole period compared to 44.9% (38.3%-51.7%) elsewhere. In 2008, the difference was more marked: 93.3% (95 CI 68-99.8%) at Harefield and 42% (28.1%- 56.8%) elsewhere. The UKCTA report commented that the high PAE rate "may be due, at least in part, to the risk profile of patients transplanted" (see paragraphs 3.7-3.11 below).*
