Background: Adherence to evidence-based guidelines for the treatment of coronary artery disease (CAD) is suboptimal. Our goal was to determine whether the performance achievement award program for Get With The Guidelines-Coronary Artery Disease (GWTG-CAD) was associated with global and sustained adherence to evidence-based guidelines for acute myocardial infarction.
Methods: Adherence to evidence-based guidelines was assessed in 170,061 hospitalized acute myocardial infarction patients from 418 US hospitals participating in GWTG-CAD from 2000 to 2008. Hospitals that received a performance achievement award by attaining 85% adherence with 6 GWTG performance measures for at least 12 consecutive months were compared with those that had enrolled in the GWTG-CAD and had not attained this level of adherence. The outcome measures were change in adherence for 6 GWTG performance measures, 9 GWTG quality measures, a composite score, and an all-or-none measure. Generalized estimating equations were used to provide valid inference accounting for the within site correlation.
Results: Hospitals that maintained 85% adherence with GWTG performance measures for at least 12 consecutive months had a higher composite score (94.78 +/- 15.99% vs. 89.72 +/- 21.37, P < 0.0001) and an all-or-none measure (87.17% vs. 75.15%, P < 0.0001) compared with hospitals that had not yet attained this level of adherence. Hospital adherence with performance and quality measures generally improved over time.
Conclusions: In conclusion, the performance achievement award program for GWTG-CAD was associated with global and sustained adherence to evidence-based guidelines. Our data suggest that this tool is a useful component of a quality improvement initiative and should be considered for other similar programs.
