Objective: Intensive care unit length of stay (ICU LOS) accounts for a large percent of inpatient cost following cardiac surgery. The Society of Thoracic Surgeons (STS) risk calculator predicts total LOS but does not discriminate between ICU and non-ICU time. We sought to develop a predictive model of prolonged ICU LOS.

Methods: Adult patients undergoing STS index operations within a regional collaborative (2014-2021) were included. Prolonged ICU LOS was defined as ICU care for ≥72 hours postoperatively. A logistic regression model was utilized to develop a prediction model for the prolonged ICU LOS with pre-specified risk factors identified from our previous single center study. Internal prediction model validation was determined by bootstrapping resampling method. The prediction model performance was assessed by measures of discrimination and calibration.

Results: We identified 37,519 patients that met inclusion criteria with 11,801 (31.5%) patients experiencing prolonged ICU stay. From the logistic regression model, there were significant associations between prolonged ICU LOS and all pre-specified factors except sleep apnea (all p<0.05). MELD, preoperative intra-aortic balloon pump use, and procedure types were the most significant predictors of prolonged ICU LOS (all p<0.0001). Our prediction model had not only a good discrimination power (bootstrapped-corrected C-index=0.71) but also excellent calibration (bootstrapped-corrected mean absolute error=0.005).

Conclusions: Prolonged ICU stay following cardiac surgery can be predicted with good predictive accuracy utilizing preoperative data and may aid in patient counseling and resource allocation. Through use of a state-wide database, the application of this model may extend to other practices.

目的:重症监护室的住院时间(ICU LOS)占心脏手术后住院费用的很大一部分。胸外科医师协会(STS)的风险计算器可预测总住院时间,但不能区分重症监护室和非重症监护室的时间。我们试图建立一个 ICU LOS 延长的预测模型:方法:纳入在区域协作组织内接受 STS 指数手术(2014-2021 年)的成人患者。ICU LOS延长的定义是术后ICU护理时间≥72小时。我们利用逻辑回归模型建立了一个 ICU LOS 延长的预测模型,其中包含了我们之前的单中心研究中确定的预先指定的风险因素。预测模型的内部验证采用引导重采样法。预测模型的性能通过辨别度和校准度进行评估:我们确定了符合纳入标准的 37,519 名患者,其中 11,801 名(31.5%)患者经历了 ICU 住院时间延长。从逻辑回归模型来看,ICU LOS 延长与除睡眠呼吸暂停外的所有预设因素均有显著相关性(所有 pConclusions):利用术前数据可以很准确地预测心脏手术后重症监护室住院时间的延长,有助于患者咨询和资源分配。通过使用全州范围的数据库,该模型的应用范围可扩展至其他实践。

Background: Esophagectomy is central to curative therapy for esophageal cancer (EC). Perioperative outcomes affect both disease-free and overall survival in oncological esophageal surgery. The adoption of robotic techniques may improve surgical outcome. However, the complex nature of perioperative outcomes is not adequately captured by individual quality measures.

Methods: All patients after minimally invasive esophagectomy (MIE) or robotic-assisted MIE (RAMIE) junction between 2015 and 2022 were included. Textbook outcome was defined as negative resection margins (R0), retrieval of >20 lymph nodes, no major complications, reinterventions, ICU readmission, 30-day readmission or mortality and hospital stay <21 days. Individual propensity scores were calculated using a logistic regression model. Factors affecting TO were evaluated using a logistic regression model while multivariate Cox proportional-hazards model was used to evaluate TO and survival.

Results: Of 236 patients included in this study, 106 (44.91%) achieved TO. TO was achieved in 71 cases after MIE (n=71 (41.21%)) and 31 after RAMIE (n=31 (57.41%)(p=0.036). RAMIE was associated with achievement of TO (OR: 2.01; 95% CI: 1.07-3.80; p=0.031) in the overall cohort. Achievement of TO was due to a reduction in major complications in the RAMIE group. Patients with perioperative TO had a higher 3 year disease-free survival (DFS) rate and overall survival rate (UV: HR 2.49, 95% CI: 1.18-5.26, p=0.016; MV: HR 4.30, 95% CI: 1.60-11.55, p=0.004) compared to those without perioperative TO and disease-free survival (UV: HR 2.28, 95% CI: 1.24-4.19, p=0.008; MV: HR 2.82, 95% CI: 1.26-6.32, p=0.011) after 2 year follow up.

Conclusions: RAMIE is associated with an increased TO achievement. Achieving TO is associated with enhanced long-term survival in esophageal cancer patients and warrants continued emphasis on surgical quality improvement.

背景:食管切除术是食管癌(EC)根治性治疗的核心。围手术期的结果会影响食管肿瘤手术的无病生存率和总生存率。采用机器人技术可改善手术效果。然而,围手术期结果的复杂性并不能通过单独的质量衡量标准得到充分体现:方法:纳入2015年至2022年间所有接受微创食管切除术(MIE)或机器人辅助食管切除术(RAMIE)的患者。教科书上的结果被定义为切除边缘阴性(R0)、取回>20个淋巴结、无重大并发症、再干预、ICU再入院、30天再入院或死亡率和住院时间 结果:在纳入的236名患者中,有1名患者的切除边缘为阴性:本研究共纳入 236 例患者,其中 106 例(44.91%)实现了 TO。71例患者在MIE(71例(41.21%))和31例患者在RAMIE(31例(57.41%))后实现了TO(P=0.036)。在整个队列中,RAMIE与TO的实现相关(OR:2.01;95% CI:1.07-3.80;P=0.031)。在RAMIE组中,主要并发症的减少导致了TO的实现。围手术期TO患者的3年无病生存(DFS)率和总生存率更高(UV:HR 2.49,95% CI:1.18-5.26,p=0.016;MV:HR 4.30,95% CI:1.60-11.55,p=0.结论:RAMIE与围手术期TO和无病生存率(UV:HR 2.28,95% CI:1.24-4.19,p=0.008;MV:HR 2.82,95% CI:1.26-6.32,p=0.011)增加有关:结论:RAMIE与TO成就的增加有关。结论:RAMIE与食管癌术后长期生存率的提高有关。

Objective: Chatbot use has developed a presence in medicine and surgery and has been proposed to help guide clinical decision making. However, the accuracy of information provided by artificial intelligence (AI) platforms has been questioned. We evaluated the performance of 4 popular chatbots on a board-style examination and compared results with a group of board-certified thoracic surgeons.

Methods: Clinical scenarios were developed within domains based on the ABTS Qualifying Exam. Each scenario included three stems written with the Key Feature methodology related to diagnosis, evaluation, and treatment. Ten scenarios were presented to ChatGPT-4, Bard (now Gemini), Perplexity, and Claude 2, as well as randomly selected ABTS-certified surgeons. The maximum possible score was 3 points per scenario. Critical failures were identified during exam development; if they occurred in any of the 3 stems the entire question received a score of 0. The Mann-Whitney U test was used to compare surgeon and chatbot scores.

Results: Examinations were completed by 21 surgeons, the majority of whom (14; 66%) practiced in academic or university settings. The median score per scenario for chatbots was 1.06compared to 1.88 for surgeons (difference 0.66, p=0.019). Surgeon median scores were better than chatbot median scores for all except two scenarios. Chatbot answers were significantly more likely to be deemed critical failures compared to those provided by surgeons (median 0.50 per chatbot/scenario vs. 0.19 per surgeon/scenario; p=0.016).

Conclusions: Four popular chatbots performed at a significantly lower level than board-certified surgeons. Implementation of AI should be undertaken with caution in clinical decision making.

目的聊天机器人已在医学和外科领域得到应用,并被建议用于指导临床决策。然而,人工智能(AI)平台所提供信息的准确性一直受到质疑。我们评估了 4 个流行聊天机器人在董事会式考试中的表现,并将结果与一组经董事会认证的胸外科医生进行了比较:方法:根据 ABTS 资格考试的领域开发了临床场景。每个场景包括三个主干,分别用与诊断、评估和治疗相关的关键特征方法编写。ChatGPT-4 、Bard(现为 Gemini)、Perplexity 和 Claude 2 以及随机抽取的 ABTS 认证外科医生对 10 个情景进行了测试。每个场景的最高得分为 3 分。曼-惠特尼 U 检验用于比较外科医生和聊天机器人的得分:21名外科医生完成了考试,其中大部分(14人,66%)在学术或大学环境中执业。聊天机器人每个场景的中位分数为 1.06,而外科医生为 1.88(差异为 0.66,P=0.019)。除两个场景外,外科医生的中位数得分均高于聊天机器人的中位数得分。与外科医生提供的答案相比,聊天机器人的答案更容易被视为关键失败(聊天机器人/情景的中位数为 0.50,外科医生/情景的中位数为 0.19;P=0.016):结论:四种流行的聊天机器人的手术水平明显低于经委员会认证的外科医生。在临床决策中应谨慎使用人工智能。

Objective: Thoracic surgery program directors (PDs) are key mentors for the next generation of cardiothoracic surgeons and surgeon-scientists. This study evaluates the industry payments to PDs compared to other practicing thoracic surgeons to assess potential conflicts of interest and their influence.

Methods: PDs were identified using the Electronic residency application system (ERAS) and their National provider identifiers (NPIs). Industry payments from 2015 to 2021 were extracted from the OpenPayments (cms.gov) database. We analyzed the number and types of payments, including consulting fees, speaking engagements, and research-related contributions. Payments were compared by PD characteristics such as gender, specialty, and academic metrics using the Chi-square test and Kruskal-Wallis test.

Results: All 77 identified PDs (66 males and 11 females) received industry payments, totaling $14,094,422 across 8,028 transactions. The median payment was $16716, with maximum reaching $2,661,001. Male PDs and those in cardiac specialties received significantly higher payments. Research funding for PDs was predominantly awarded to males (100%). Significant disparities were observed in industry payments to PDs compared to non-PDs, especially in food and beverage, and educational activities. PDs initially received more than double the research payments compared to non-PDs in the early years. This disparity reduced significantly by 2021, reflecting a move towards more equitable research funding.

Conclusion: The substantial payment to PDs reflects their significant role in thoracic surgery, yet raises concerns regarding potential influence on trainees. These findings underscore the need for increased transparency and measures to address disparities in industry support, particularly concerning gender and specialty.

目的:胸外科项目主任 (PD) 是下一代心胸外科医生和外科医生科学家的重要导师。本研究评估了与其他执业胸外科医生相比,胸外科项目主任的行业报酬,以评估潜在的利益冲突及其影响:方法:使用电子住院医师申请系统 (ERAS) 及其国家提供者标识符 (NPI) 识别住院医师。从 OpenPayments (cms.gov) 数据库中提取了 2015 年至 2021 年的行业付款。我们分析了付款的数量和类型,包括咨询费、演讲活动和研究相关贡献。我们使用Chi-square检验和Kruskal-Wallis检验比较了PD的性别、专业和学术指标等特征:所有 77 名已确认的 PD(66 名男性和 11 名女性)都收到了行业付款,总额达 14,094,422 美元,涉及 8,028 笔交易。付款中位数为 16716 美元,最高达 2,661,001 美元。男性和心脏专科的博士获得的报酬明显更高。博士的研究经费主要由男性获得(100%)。与非专科医师相比,专科医师获得的行业报酬存在显著差异,尤其是在餐饮和教育活动方面。在最初几年,专业人员获得的研究经费是非专业人员的两倍多。到 2021 年,这一差距明显缩小,反映出研究经费正朝着更加公平的方向发展:结论:向胸外科医生支付巨额研究经费反映了他们在胸外科中的重要作用,但也引发了对受训者潜在影响的担忧。这些发现强调了提高透明度和采取措施解决行业支持差异的必要性,尤其是在性别和专业方面。

Background: The current study aims to report the presentation of the malperfusion syndrome in patients with acute Type A aortic dissection admitted to surgery and its impact on mortality.

Methods: Data were retrieved from the multicenter European Registry of Type A Aortic Dissection (ERTAAD). The Penn classification was utilized to categorize malperfusion syndromes. A machine learning algorithm was applied to assess the multivariate interaction's importance regarding in-hospital mortality.

Results: A total of 3,902 consecutive patients underwent repair for Acute Type A Aortic Dissection. Local malperfusion syndrome occurred in 1,584 (40.58%) patients. Multi-organ involvement occurred in 582 patients (36.74%) whereas 1,002 patients (63.26%) had single-organ malperfusion. The prevalence was the highest for cerebral (21.27%) followed by peripheral (13.94%), myocardial (9.7%), renal (9.33%), mesenteric (4.15%), and spinal malperfusion (2.10%). Multi-organ involvement predominantly occurred in organs perfused by the downstream aorta. Malperfusion significantly increased mortality risk (p < 0.001, OR 1.95 ± 0.29). The Boruta machine learning algorithm identified the Penn classification as significantly associated with in-hospital mortality (p< 0.0001, variable importance = 7.91), however, 8 other variables yielded higher prediction importance. According to the Penn classification mortality rates were for Penn A = 12.38%, Penn B = 20.71% Penn C = 28.90%, and Penn BC = 31.84% respectively.

Conclusions: Nearly half of the examined cohort presented with signs of malperfusion syndrome predominantly due to local involvement. More than one-third of patients with local malperfusion syndrome had a multivessel involvement. Furthermore, different levels of Penn classification can be used only as a first tool for preliminary stratification of early mortality risk.

背景:本研究旨在报告入院手术的急性A型主动脉夹层患者的灌注不良综合征表现及其对死亡率的影响:本研究旨在报告接受手术的急性 A 型主动脉夹层患者出现灌注不良综合征的情况及其对死亡率的影响:数据取自欧洲 A 型主动脉夹层多中心登记处 (ERTAAD)。采用宾夕法尼亚分类法对灌注不良综合征进行分类。应用机器学习算法评估多变量相互作用对院内死亡率的重要性:共有3902名急性A型主动脉夹层患者接受了修复手术。1584例(40.58%)患者出现局部灌注不良综合征。582名患者(36.74%)出现多器官受累,1002名患者(63.26%)出现单器官灌注不良。发病率最高的是脑部(21.27%),其次是外周(13.94%)、心肌(9.7%)、肾脏(9.33%)、肠系膜(4.15%)和脊髓(2.10%)灌注不良。多器官受累主要发生在下游主动脉灌注的器官。灌注不良会明显增加死亡风险(P < 0.001,OR 1.95 ± 0.29)。Boruta 机器学习算法认为宾恩分类与院内死亡率有显著相关性(p< 0.0001,变量重要性 = 7.91),但其他 8 个变量的预测重要性更高。根据宾夕法尼亚分类法,死亡率分别为宾夕法尼亚A=12.38%、宾夕法尼亚B=20.71%、宾夕法尼亚C=28.90%和宾夕法尼亚BC=31.84%:近一半的受检者出现了灌注不良综合征的症状,主要是由于局部受累。超过三分之一的局部灌注不良综合征患者有多血管受累。此外,佩恩分类的不同级别只能作为初步分层早期死亡风险的第一工具。
