Improved outcomes associated with a revised quality measure for continuing perioperative β-blockade

Area of Science:

• Cardiovascular Surgery
• Quality Improvement Initiatives
• Pharmacological Interventions

Background:

• The Surgical Care Improvement Project perioperative beta-blocker (SCIP-BB) measure was updated in 2012 to include inpatient beta-blocker continuation post-anesthesia care unit discharge.
• Evaluating adherence to both original and revised SCIP-BB measures is crucial for understanding their impact on patient safety.

Purpose of the Study:

• To assess the association between adherence to the original and revised SCIP-BB measures and the occurrence of adverse events.
• To determine if updated guidelines for perioperative beta-blocker use improve patient outcomes.

Main Methods:

• A retrospective cohort study utilized national Veterans Affairs patient data from July 2006 to August 2009.
• Propensity score matching and bootstrapping were employed to analyze the association between SCIP-BB measure adherence and major adverse cardiovascular or cerebrovascular events (MACCEs), including cardiovascular events, cerebrovascular events, and 30-day mortality.

Main Results:

• Adherence to the original SCIP-BB measure (91.3%) was not associated with reduced MACCEs but was linked to a threefold increase in cerebrovascular events.
• Adherence to the revised SCIP-BB measure (80.4%) was associated with significant reductions in MACCEs, cardiovascular events, and 30-day mortality.
• The revised measure showed no association with increased cerebrovascular events.

Conclusions:

• The original SCIP-BB measure's adherence did not improve cardiovascular outcomes and was associated with higher cerebrovascular event rates.
• Beta-blocker continuation aligned with the revised SCIP-BB measure demonstrated improved patient outcomes, including reduced MACCEs and mortality.
• Performance measures require rigorous testing before implementation; findings for the revised SCIP-BB measure warrant post-implementation evaluation.
