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.

持续质量改进委员会对经皮冠状动脉介入治疗患者预后的影响：一项单中心回顾性队列研究

背景：持续质量改进（CQI）项目旨在提高经皮冠状动脉介入治疗（PCI）的安全性和效率。本分析评估了在大型学术中心实施多学科导管实验室CQI委员会后PCI实践模式和结果的变化。方法回顾性队列研究2018年1月至2024年6月的PCI手术，使用国家心血管数据登记中心的CathPCI数据。比较实施CQI前（2018- 2022年10月）和实施CQI后（2022年11月-2024年11月）的结果和实践模式。预先指定的主要终点是pci术后急性肾损伤、术中血红蛋白变化和当日出院。结果2759例PCI患者（cqi前1783例，cqi后976例），月PCI量增加（30.7 ~ 48.2例/月，P < 001）。cqi后，径向显影剂使用率增加（33.4% ~ 58.9%,P < 0.001），平均造影剂体积降低（188 ~ 153 mL, P < 0.001）。cqi后主要结局改善：急性肾损伤减少（14.3% ~ 9.7%,P = 0.01），平均围手术期血红蛋白变化减少（0.65 ~ 0.54 g/dL, P = 0.004），当日出院增加（13.0% ~ 24.7%,P < 001）。总体并发症发生率和住院死亡率保持稳定。结论导尿实验室CQI委员会的实施与PCI安全性和出院效率的提高以及手术量的增加和病例组合的演变具有暂时性的相关性。这些发现支持cqi驱动的方法来优化PCI护理交付。
