Implementation of the Canadian Cardiovascular Society guidelines for perioperative risk assessment and management: an interrupted time series study.

Purpose: The Canadian Cardiovascular Society (CCS) guidelines for patients undergoing non-cardiac surgery address the lack of standardized management for patients at risk of perioperative cardiovascular complications. Our interdisciplinary group evaluated the implementation of these guidelines.

Methods: We used an interrupted time series design to evaluate the effect of implementation of the CCS guidelines, using routinely collected hospital data.
