ObjectiveTo evaluate the impact of a simple written algorithm of early postoperative beta-blocker administration on daily practices.DesignA prospective, single center observational study.SettingA 16-bed cardiac surgical intensive care unit in a university teaching hospital.PatientsOne hundred twenty-five consecutive adult patients chronically treated with beta-blockers and scheduled for conventional cardiac surgery.InterventionsTwo successive 4-month phases: Phase 1 = uncontrolled early postoperative beta-blocker administration (n = 73) and phase 2 = beta-blocker administration by an institutional written algorithm using incremental doses of bisoprolol and/or esmolol (n = 52).Measurements and Main ResultsThe main endpoint was the number of patients receiving beta-blockers on the morning of postoperative day 1. Secondary endpoints were the number of patients receiving beta-blockers on the morning of postoperative day 1 and reaching the targeted therapeutic goal and the incidence of postoperative atrial fibrillation in the intensive care unit. A 79% increase in the number of patients receiving beta-blockers on the morning of postoperative day 1 (42% v 75%, p<0.001) was observed during the second phase of the study. The number of patients receiving beta-blockers on the morning of postoperative day 1 and reaching the targeted therapeutic goal was increased significantly by 127% (33% v 75%, p<0.001). The incidence of atrial fibrillation was similar between both phases of the study: 37% versus 31%, p = 0.567.ConclusionsA simple written algorithm markedly improved early postoperative continuation of beta-blockers in chronically treated patients undergoing conventional cardiac surgery.
