Background: The 1996 atenolol study provided evidence that perioperative beta-adrenergic receptor blockade (beta-blockade) reduced postsurgical mortality. In 1998, the indications for perioperative beta-blockade were codified as the Perioperative Cardiac Risk Reduction protocol and implemented at the San Francisco Veterans Administration Medical Center, San Francisco, California. The present study analyzed the association of the pattern of use of perioperative beta-blockade with perioperative mortality since introduction of the Perioperative Cardiac Risk Reduction protocol. Methods: Epidemiologic analysis of the operations undertaken since 1996 at the San Francisco Veterans Administration Medical Center was performed. The pattern of use of perioperative beta-blockade was divided into four groups: None, Addition, Withdrawal, and Continuous. Logistic regression, survival analysis, and propensity analysis were performed. Results: A total of 38,779 operations were performed between 1996 and 2008. In patients meeting Perioperative Cardiac Risk Reduction indications for perioperative beta-blockade, Addition is associated with a reduction in 30-day (odds ratio [OR], 0.52; 95% confidence interval [CI], 0.33 to 0.83; P = 0.006) and 1-yr mortality (OR, 0.64; 95%, CI 0.51 to 0.79; P < 0.0001). Continuous is associated with a reduction in 30-day (OR, 0.68; 95% CI, 0.47 to 0.98; P = 0.04) and 1-yr mortality (OR, 0.82; 95% CI, 0.67 to 1.0; P = 0.05). Withdrawal is associated with an increase in 30-day (OR 3.93, 95% CI, 2.57 to 6.01; P less than 0.0001) and 1-yr mortality (OR, 1.96; 95% CI, 1.49 to 2.58; P < 0.0001). Conclusion: Perioperative beta-blockade administered according to the Perioperative Cardiac Risk Reduction protocol is associated with a reduction in 30-day and 1-yr mortality. Perioperative withdrawal of beta-blockers is associated with increased mortality.
