Implementation of a Multidimensional Strategy to Reduce Post-PCI Bleeding Risk.

Background: The American College of Cardiology Reduce the Risk: PCI Bleed Campaign was a hospital-based quality improvement campaign designed to reduce post-percutaneous coronary intervention (PCI) bleeding events. The aim of the campaign was to provide actionable evidence-based tools for participants to review, adapt, and adopt, depending upon hospital resources and engagement.

Methods: We used data from 8 757 737 procedures in the National Cardiovascular Data Registry between 2015 and 2021 to compare patient and hospital characteristics and bleeding outcomes among campaign participants (n=195 hospitals) and noncampaign participants (n=1384). Post-PCI bleeding risk was compared before and after campaign participation. Multivariable hierarchical logistic regression was used to determine the adjusted association between campaign participation and post-PCI bleeding events. Prespecified subgroups were examined.

Results: Campaign hospitals were more often higher volume teaching facilities located in urban or suburban locations. After adjustment, campaign participation was associated with a significant reduction in the rate of bleeding (bleeding: adjusted odds ratio, 0.61 [95% CI, 0.53-0.71]). Campaign hospitals had a greater decrease in bleeding events than noncampaign hospitals. In a subgroup analysis, the reduction in bleeding was noted in non-ST-segment-elevation acute coronary syndrome and ST-segment-elevation myocardial infarction patients, but no significant reduction was seen in patients without acute coronary syndrome.

Conclusions: Participation in the American College of Cardiology Reduce the Risk: PCI Bleed Campaign was associated with a significant reduction in post-PCI bleeding. Our results underscore that national quality improvement efforts can be associated with a significant impact on PCI outcomes.
