A Comparative Effectiveness Analysis of the Implementation of Surgical Safety Checklists in a Tertiary Care Hospital.

Importance: The appropriately coached implementation of surgical safety checklists (SSCs) reduces the incidence of perioperative complications and 30-day mortality of patients undergoing surgery. The association of the introduction of SSCs with 90-day mortality remains unclear.

Objective: To assess the association between the implementation of SSCs and all-cause 90- and 30-day mortality rates.
