Abstract
Background: Continuous quality improvement (CQI) programs aim to enhance procedural safety and efficiency in percutaneous coronary intervention (PCI). This analysis evaluates changes in PCI practice patterns and outcomes after implementation of a multidisciplinary catheterization laboratory CQI committee at a large academic center.
Methods: A retrospective cohort study was conducted regarding PCI procedures from January 2018 to June 2024 using National Cardiovascular Data Registry CathPCI data. Outcomes and practice patterns were compared before (pre-CQI: 2018-October 2022) versus after CQI implementation (post-CQI: November 2022-2024). Prespecified primary end points were post-PCI acute kidney injury, periprocedural hemoglobin change, and same-day discharge.
Results: Among 2759 PCI cases (1783 pre-CQI; 976 post-CQI), monthly PCI volume increased (30.7-48.2 cases/mo, P < .001). Post-CQI, radial access use increased (33.4%-58.9%, P < .001) and mean contrast volume decreased (188-153 mL, P < .001). Primary outcomes improved post-CQI: acute kidney injury decreased (14.3%-9.7%, P = .01), mean periprocedural hemoglobin change decreased (0.65-0.54 g/dL, P = .004), and same-day discharge increased (13.0%-24.7%, P < .001). Overall complication rates and in-hospital mortality remained stable.
Conclusions: Implementation of a catheterization laboratory CQI committee was temporally associated with improved PCI safety and discharge efficiency alongside increased procedural volume and evolving case mix. These findings support CQI-driven approaches to optimize PCI care delivery.
