B-FREE is a pragmatic, multicentre, cluster crossover trial evaluating whether a policy limiting the use of intra-operative benzodiazepine reduces post-operative delirium when compared with a policy of 'ad libitum' administration. The knowledge generated by this study will provide the basis for cardiac anesthesia practice guidelines.

Primary Outcome

Delirium assessed up to 72 hours after surgery using standardized and validated delirium scales
