BACKGROUND Patients have substantial variability in perioperative outcomes after left ventricular assist device (LVAD) implant. A perioperative multidimensional tool integrating mortality, adverse events (AEs), and patient-reported outcomes to assist in quality improvement initiatives is needed. METHODS Patients undergoing HeartMate 3 LVAD implant (January 1, 2017 to January 31, 2024) in the Society of Thoracic Surgeons' Intermacs registry were studied. Cox proportional hazard multivariable analyses incorporating AEs as time-varying covariates for mortality out to 180 days was used to generate the INtermacs Short term composITE quality score (INSITE score derivation), reflecting the adjusted hazard ratio (HR) for mortality contributed by each AE, applying the global ranking methodology. In those alive and on support at 6 months, multivariable logistic regression (odds ratio) was used to examine the impact of AEs on health-related quality of life (QOL) at 180 days, captured through the INSITE-QOL score. Failure to achieve ≥1 point increase in visual analog scale from baseline was the event. RESULTS Of 13,148 patients, 4,389 (33.4%) suffered at least 1 AE or death through 180 days. Stroke (survival: HR 13.1; QOL: HR 1.7), dialysis (survival: HR 31.4; QOL: HR 4.2), prolonged respiratory failure (survival: HR 5.7; QOL: HR 2.3), reoperation (survival: HR 3.4; QOL: HR 1.6), and right heart failure (survival: 5.0; QOL: HR 1.4), contributed to both mortality and failure to improve QOL at 180 days (all p < 0.05). The median INSITE and INSITE-QOL scores were 0.0 [0.0, 1.6] and 0.0 [0.0, 0.0], respectively. At 9.4% (n = 17) of centers, a high INSITE score (≥13) was present in 15% of patients, while the top 25% of centers had perfect INSITE-QOL scores in at least 75% of patients. CONCLUSIONS AEs after LVAD confer differential impact on mortality and QOL, enabling the development of global rank outcome scores. Given the high mortality hazard conferred by 180-day AEs, center-specific quality interventions aimed at reducing early complications provide the greatest opportunity to improve long-term survival and QOL.

定义最佳左心室辅助装置的短期结局可能有助于了解程序质量评估。



背景 患者在植入左心室辅助装置 (LVAD) 后围手术期结局存在很大差异。需要一个整合死亡率、不良事件 (AEs) 和患者报告结果的围手术期多维工具,以协助质量改进计划。方法 对在胸外科医师协会 Intermacs 登记处接受 HeartMate 3 LVAD 植入 (2017 年 1 月 1 日至 2024 年 1 月 31 日) 的患者进行了研究。Cox 比例风险多变量分析将 AE 作为 180 天内死亡率的时变协变量用于生成 INtermacs 短期合成质量评分(INSITE 评分推导),反映每个 AE 贡献的调整后风险比 (HR),应用全球排名方法。在存活且在 6 个月时接受支持的患者中,使用多变量 logistic 回归 (比值比) 来检查 AE 对 180 天时健康相关生活质量 (QOL) 的影响,通过 INSITE-QOL 评分捕获。视觉模拟量表未能从基线增加 ≥1 分是事件。结果 在 13,148 名患者中,4,389 名 (33.4%) 在 180 天内至少发生 1 次 AE 或死亡。中风 (存活率: HR 13.1;QOL:HR 1.7)、透析(存活率:HR 31.4;QOL: HR 4.2)、延长呼吸衰竭 (生存率: HR 5.7;QOL: HR 2.3)、再次手术 (存活率: HR 3.4;QOL: HR 1.6) 和右心衰竭 (生存率: 5.0;QOL: HR 1.4),导致 180 天死亡率和未能改善 QOL (均 p < 0.05)。INSITE 和 INSITE-QOL 评分中位数分别为 0.0 [0.0, 1.6] 和 0.0 [0.0, 0.0]。在 9.4% (n = 17) 的中心中,15% 的患者存在高 INSITE 评分 (≥13),而前 25% 的中心至少有 75% 的患者具有完美的 INSITE-QOL 评分。 结论 LVAD 后的 AE 对死亡率和 QOL 的影响不同,从而能够开发全球排名结果评分。鉴于 180 天 AE 带来的高死亡风险,旨在减少早期并发症的中心特异性质量干预措施为提高长期生存率和 QOL 提供了最大的机会。
