Routine data may bias aortic surgery mortality estimates; leaves open their reliability for performance benchmarking.
Can routine hospital data accurately measure surgical performance and postoperative mortality in aortic surgery?
Crude mortality rates derived from routine hospital data are subject to significant bias and distortion due to coding inaccuracies and case-mix differences, making them unreliable as standalone performance indicators for aortic surgery.
