    背景:外科医生倦怠的增长是非常值得关注的。当我们努力重新想象手术实践时,准确了解外科医生的倦怠程度至关重要。我们的目标是确定当前SAGES外科医生的职业倦怠和生活质量(QOL)的患病率。
    方法:对SAGES成员进行了电子调查,以建立QOL的当前基线,倦怠,抑郁症,和职业满意度。为了评估结果,我们使用了经过验证的医务人员Maslach倦怠清单,医学成果研究简表,和精神疾病的初级保健评估。所有评分都遵循经过验证的基于规范的方法。
    结果:在4194名活跃成员中,604人回答(14.40%)。69%达到倦怠阈值,高度的情绪疲惫和人格解体,个人成就感低。81%的人报告说“处于绳索的尽头”,74%的人感到情绪疲惫,65%的人感觉每天都用完。几乎所有人都关心他们的病人发生了什么(96%),容易理解患者的感受(84.3%),并且能够有效地处理患者的问题(87.6%)。然而,受访者从不,很少,或偶尔感到精力充沛(77.5%)或有职业成就感(57.8%)。总体QOL评分为69/100,精神评分低于身体评分(62.69(SD10.20)vs.77.27(SD22.24))。超过一半的受访者符合抑郁标准。虽然77%的人支持他们再次成为医生,不到一半的人会选择再次手术或推荐给他们的孩子手术。此外,不到三分之一的人认为工作为他们的个人生活留出了足够的时间。
    结论:参与SAGES的外科医生报告了惊人的高倦怠和抑郁率。尽管经历了情绪疲惫和人格解体,他们对病人护理保持坚定的承诺。这些发现可能反映了外科医生的更广泛状况,强调迫切需要采取行动解决这一关键问题。
    BACKGROUND: The growth of surgeon burnout is of significant concern. As we work to reimagine the practice of surgery, an accurate understanding of the extent of surgeon burnout is essential. Our goal was to define the current prevalence of burnout and quality of life (QOL) among SAGES surgeons.
    METHODS: An electronic survey was administered to SAGES members to establish a current baseline for QOL, burnout, depression, and career satisfaction. To assess outcomes, we utilized the validated Maslach Burnout Inventory for Medical Personnel, the Medical Outcomes Study Short Form, and the Primary Care Evaluation of Mental Disorders. All scoring followed validated norm-based methods.
    RESULTS: Of 4194 active members, 604 responded (14.40%). 69% met burnout threshold, with high levels of emotional exhaustion and depersonalization, and low personal accomplishment. 81% reported \"being at the end of their rope\", 74% felt emotionally drained, and 65% felt used up daily. Nearly all maintained caring about what happened to their patients (96%), easily understanding how their patients feel (84.3%) and being capable of dealing effectively with their patient\'s problems (87.6%). However, respondents never, rarely, or occasionally felt energetic (77.5%) or experienced a sense of professional accomplishment (57.8%). The overall QOL score was 69/100, with lower Mental than Physical scores (62.69 (SD 10.20) vs.77.27 (SD 22.24)). More than half of respondents met depression criteria. While 77% supported they would become a physician again, less than half would choose surgery again or recommend surgery to their children. Furthermore, less than a third felt work allowed sufficient time for their personal lives.
    CONCLUSIONS: Participating SAGES surgeons reported alarmingly high rates of burnout and depression. Despite experiencing emotional exhaustion and depersonalization, they maintained a strong commitment to patient care. These findings likely reflect the broader state of surgeons, underscoring the urgent need for action to address this critical issue.

    目的:监测住院医师的患者预后对提高手术性能至关重要;然而,在当前的外科培训环境中,很少提供针对居民的随访。居民个人的手术表现与患者的临床结局之间是否存在相关性仍未确定。在这项研究中,我们的目标是使用风险调整后的患者结局作为一种教育工具来跟踪个体手术受训者的表现.
    方法:对美国外科医生学会国家外科质量改进计划(ACSNSQIP)阑尾切除术和部分结肠切除术(2013-2021年)进行检查。包括进行≥25次手术的居民。主要结局是ACSNSQIP定义的发病率,使用估计的发病率概率进行调整。发病率与预期比率(O/E)测量的总体表现和风险调整累积总和(RA-CUSUM)方法代表手术住院医师随时间的表现。
    方法:学术四级护理机构。
    方法:参与手术的最高级别的外科住院医师,并纳入培训质量计划。
    结果:共检查了449例手术。12名居民进行了343例阑尾切除术。7位居民(每次29.3±5.1次手术)没有任何术后发病率,并且显示出优于预期的患者预后。三名居民在第七次/第十一次/第十五次阑尾切除术后没有发病。两名居民(病例数29、33)的O/E比>3。由4名居民进行的部分结肠切除术(n=106)有2名居民(病例量30、26)的结果好于预期,2名患者的结果差于预期(病例量25、25)。
    结论:术后患者预后的纵向监测为受训者自我反省和系统检查提供了机会。RA-CUSUM方法提供序贯监测,当受训者的RA-CUSUM结果显示发病率高于预期时,可以进行早期评估和干预。
    OBJECTIVE: Monitoring resident trainees\' patient outcomes is essential to improving surgical performance; however, resident-specific follow-up is rarely provided in the current surgical training environment. Whether there is a correlation between individual resident\'s surgical performance and patients\' clinical outcomes remains undefined. In this study, we aimed to use risk-adjusted patient outcomes as an educational tool to track individual surgical trainee performance.
    METHODS: American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) appendectomy and partial colectomy operations (2013-2021) were examined. Residents performing ≥25 operations were included. The primary outcome was ACS NSQIP-defined morbidity adjusted using estimated probability of morbidity. Observed-to-expected ratios (O/E) of morbidity measured overall performance and risk-adjusted cumulative sum (RA-CUSUM) methodology represented surgical resident\'s performance over time.
    METHODS: Academic quaternary care institution.
    METHODS: Highest-ranking surgical resident participating in an operation and included in Quality In-Training Initiative.
    RESULTS: A total of 449 operations were examined. 12 residents performed 343 appendectomy operations. 7 residents (29.3 ± 5.1 operations each) did not have any postoperative morbidity and demonstrated better-than-expected patient outcomes. Three residents did not have morbidity after their seventh/eleventh/fifteenth appendectomies. Two residents (case volume 29, 33) had an O/E ratio > 3. Partial colectomy (n = 106) performed by 4 residents had 2 residents (case volume 30, 26) with better-than-expected outcomes and 2 with worse-than-expected (case volume 25, 25).
    CONCLUSIONS: Longitudinal monitoring of postoperative patient outcomes provides an opportunity for trainee self-reflection and system examination. RA-CUSUM methodology offers sequential monitoring allowing for early evaluation and intervention when RA-CUSUM results for a trainee demonstrate higher-than-expected morbidity.

    背景:自《橙皮书》以来,要求I级和II级创伤中心提供同等资源。“这项研究评估了实质性器官损伤(SOI)与创伤性脑损伤(TBI)的I级和II级管理之间的差异。
    方法:我们对2013年至2021年成年人(≥18岁)的国家创伤数据库进行了回顾性审查,在I级或II级创伤中心治疗患有TBI和SOI的钝性创伤患者。
    结果:确定了48,479例TBI和SOI患者,一级中心32611(67.3%)。未调整的开腹手术的发生率在I级较高(14.5%vs11.7%,P<0.001),和血管造影率相似(3.3%vs3.4%,P0.717)。对稳定患者(SBP≥100)的亚组分析显示,在II级非手术治疗中增加(87.3%vs88.7%,P<0.001)和剖腹手术减少(9.9%vs8.3%,P<0.001)。在逻辑回归(LR)上,严重的TBI,高级SOI,和I级创伤状态是剖腹手术的预测因素。Logistic回归显示轻度/中度TBI伴高级别SOI和II级与血管造影的使用相关。未调整的死亡率略有不同(14.8%vs13.4%,P<0.001),但与LR的创伤水平无关.
    结论:非手术治疗在I级剖腹手术的II级中心更多。亚组分析显示创伤水平的死亡率没有差异。I级和II级匹配的患者在管理方面没有统计学差异。患者在两个水平上接受相似的治疗,结果和死亡率相似。
    BACKGROUND: Level-I and level-II trauma centers are required to offer equivalent resources since \"The Orange Book.\" This study evaluates differences between level-I and level-II management of solid organ injury (SOI) with traumatic brain injury (TBI).
    METHODS: We conducted a retrospective review of the National Trauma Data Banks from 2013 to 2021 of adult (≥18 years), blunt trauma patients with both TBI and SOI treated at level-I or level-II trauma centers.
    RESULTS: 48,479 TBI and SOI patients were identified, 32,611 (67.3%) at level-I centers. Unadjusted incidence of laparotomy was higher at level I (14.5% vs 11.7%, P < 0.001), and angiography rates were similar (3.3% vs 3.4%, P 0.717). Sub-group analysis of stable patients (SBP ≥100) showed an increase in nonoperative management at level II (87.3% vs 88.7%, P < 0.001) and decrease in laparotomy (9.9% vs 8.3%, P < 0.001). On logistic regression (LR), severe TBI, high-grade SOI, and level I trauma status were predictors of laparotomy. Logistic regression showed mild/moderate TBI with high-grade SOI and level II were associated with use of angiography. Unadjusted mortality rates were slightly different (14.8% vs 13.4%, P < 0.001), but there was no association with trauma level on LR.
    CONCLUSIONS: Nonoperative management was seen more at level-II centers with laparotomy at level I. Subgroup analysis showed no difference in mortality in trauma levels. Matched patients for level I and II showed no statistical difference in management. Patients were treated similarly at both levels with similar outcomes and mortality.

    背景:创伤患者的意外再入院重症监护病房(UR-ICU)与住院时间增加以及发病率和死亡率相关。我们确定了UR-ICU的独立预测因子,并构建了一个列线图来估计再入院概率。材料和方法:我们于2019年1月至2021年12月在I级创伤中心进行了IRB批准的回顾性病例对照研究。UR-ICU患者(n=175)与未再入院(NR-ICU)患者(n=175)相匹配。进行了单变量和多变量二元线性回归分析(SPSS第28版,IBM公司),并创建了列线图(Stata18.0,StataCorpLLC)。结果:人口统计,合并症,并将损伤和住院病程相关因素作为UR-ICU的潜在预后指标。UR-ICU死亡率为22.29%,NR-ICU死亡率为6.29%(P<.001)。二元线性回归确定了七个对UR-ICU有贡献的独立预测因素:ICU入院期间的休克(P<.001)或颅内手术(P=.015),低血细胞比容(P=.001)或在ICU出院前24小时给予镇静(P<.001),积极感染治疗(P=.192)或ICU出院时白细胞增多(P=.01),和慢性阻塞性肺疾病(COPD)(P=0.002)。生成列线图以估计UR-ICU的概率并指导ICU出院适当性的决定。讨论:在创伤中,UR-ICU通常伴有不良结局和死亡。震惊,颅内手术,贫血,镇静管理,持续感染治疗,白细胞增多,COPD是UR-ICU的重要危险因素。预测列线图可能有助于更好地评估ICU出院的准备情况。
    Background: Unplanned readmission to intensive care units (UR-ICU) in trauma is associated with increased hospital length of stay and significant morbidity and mortality. We identify independent predictors of UR-ICU and construct a nomogram to estimate readmission probability. Materials and Methods: We performed an IRB-approved retrospective case-control study at a Level I trauma center between January 2019 and December 2021. Patients with UR-ICU (n = 175) were matched with patients who were not readmitted (NR-ICU) (n = 175). Univariate and multivariable binary linear regressionanalyses were performed (SPSS Version 28, IBM Corp), and a nomogram was created (Stata 18.0, StataCorp LLC). Results: Demographics, comorbidities, and injury- and hospital course-related factors were examined as potential prognostic indicators of UR-ICU. The mortality rate of UR-ICU was 22.29% vs 6.29% for NR-ICU (P < .001). Binary linear regression identified seven independent predictors that contributed to UR-ICU: shock (P < .001) or intracranial surgery (P = .015) during ICU admission, low hematocrit (P = .001) or sedation administration in the 24 hours before ICU discharge (P < .001), active infection treatment (P = .192) or leukocytosis on ICU discharge (P = .01), and chronic obstructive pulmonary disease (COPD) (P = .002). A nomogram was generated to estimate the probability of UR-ICU and guide decisions on ICU discharge appropriateness. Discussion: In trauma, UR-ICU is often accompanied by poor outcomes and death. Shock, intracranial surgery, anemia, sedative administration, ongoing infection treatment, leukocytosis, and COPD are significant risk factors for UR-ICU. A predictive nomogram may help better assess readiness for ICU discharge.

    背景:老年手术验证计划(GSV)旨在解决75岁以上患者的围手术期护理问题,目的是改善手术后的结果和功能。我们试图评估术前因素,使患者处于无法回家的风险中(即,排放到设施)。
    方法:回顾性审查2018年1月至2022年12月在参加GSV计划的转诊退伍军人管理局医疗中心接受住院手术的≥75岁患者。术前因素包括跌倒史,助行器,住房状况,函数,认知,和营养状况。术后结果是与设施(熟练护理设施和急性康复)相比,出院指定为家庭和有服务的家庭。排除标准包括术前设施居住,心脏手术,医院转院,术后并发症,临终关怀出院,或住院死亡率。
    结果:605例患者符合纳入标准,173例(29%)被排除。在剩下的432名患者中,平均年龄为79±5岁,大多数为男性,426(99%)。大多数病人已经出院回家,388(90%),与设施相比,44(10%)。有跌倒史的患者(OR:2.95,95%CI:1.56,5.57),使用行动辅助工具(OR:6.0,95%CI:2.8,12.83),部分或完全依赖(OR:4.83,95%CI:2.29,10.17),或独居者(OR:2.57,95%CI:1.08,6.07)的出院率较高。
    结论:术前活动能力受损和功能依赖性与更高的出院率相关。这些术前因素可能可以通过多学科护理团队进行修改,以降低设施放置的风险。
    BACKGROUND: The Geriatric Surgery Verification Program (GSV) was developed to address perioperative care for patients ≥75 years, with a goal of improving outcomes and functional abilities after surgery. We sought to evaluate preoperative factors that place patients at risk for inability to return home (ie, discharge to a facility).
    METHODS: Retrospective review of patients ≥75 years old who underwent inpatient surgery from January 2018 to December 2022 at a referral Veterans Administration Medical Center enrolled in the GSV program. Preoperative factors included fall history, mobility aids, housing status, function, cognition, and nutritional status. Postoperative outcomes were discharge designations as home and home with services compared to a facility (skilled nursing facility and acute rehab). Exclusion criteria included preoperative facility residence, cardiac surgery, hospital transfer, postoperative complications, hospice discharge, or in-hospital mortality.
    RESULTS: 605 patients met inclusion criteria and 173 (29%) excluded as above. Of the remaining 432 patients, mean age was 79 ± 5 and the majority were male, 426 (99%). The majority of patients were discharged home, 388 (90%), compared to a facility, 44 (10%). Patients with a fall history (OR: 2.95, 95% CI: 1.56, 5.57), utilizing a mobility aid (OR: 6.0, 95% CI: 2.8, 12.83), were partial or totally dependent (OR: 4.83, 95% CI: 2.29, 10.17), or who lived alone (OR: 2.57, 95% CI: 1.08, 6.07) had higher rates of discharge to a facility.
    CONCLUSIONS: Preoperative mobility compromise and functional dependence are associated with higher rates of discharge to a facility. These preoperative factors are possibly modifiable with multidisciplinary care teams to decrease risks of facility placement.

    我们作为外科医生的职业生涯是一些最繁忙的,也许是最受欢迎的。我们都付出了无数年的顽强努力,有时是血,经常出汗,和偶尔的眼泪,有特权照顾他人并纠正他们的疾病。我们中的许多人就像货运列车无限期地在铁轨上滚动。但是我们经常完成训练并沿着这些轨道前进,而不考虑我们在前进的道路上应该做什么,我们应该考虑采取的轨道中的分叉,也许大多数情况下,我们不考虑如何最终停止火车。我们大多数人都见证了那些继续工作的同事,是因为缺乏替代机会,缺乏退休的爱好,或者是因为对自己的衰落缺乏洞察力。从这些观察结果中诞生了这个总统小组。如你所见,它是SoCalACS的前任总统的集合,除了Freischlag博士(我们都知道,如果她从未搬离南加州,她将在某个时候担任总统)。这些演讲者中的每一位都有自己职业生涯中的独特经验,他们将与我们分享,因此我们可以暂停并考虑他们的见解和智慧,以了解如何成功和令人满意的职业生涯。
    Our careers as surgeons are some of the busiest and perhaps most sought after in existence. We have all put in countless years of tenacious effort, at times blood, frequent sweat, and occasional tears, to have the privilege to care for others and correct their ailments. Many of us are like freight trains rolling down the tracks indefinitely. But all too often we finish our training and head down those tracks without considering what stops we should make along the way, which forks in the tracks we should consider taking, and perhaps most often, we do not consider how we are going to eventually stop the train. Most of us have been witness to colleagues who keep working beyond their prime, be it for lack of alternative opportunities, lack of hobbies to retire to, or for lack of insight into their own decline. From these observations was born this presidential panel. As you can see, it is a collection of past presidents of So Cal ACS, with the exception for Dr Freischlag (who we all know would have served as president at some point had she never relocated away from Southern California). Each of these speakers has unique experience from their own careers that they will share with us so we can take pause and consider their insights and wisdom for how to navigate a successful and satisfying career.

    在克利夫兰诊所,不正确的手术计数会触发Rust代码;一种强制要求术中患者进行X射线检查的协议,放射科工作人员阅读,并在切口闭合前与外科医生讨论。对2014年11月至2022年12月的CodeRust调用进行了回顾性审查。分析了代码锈蚀案例的实时工作流程和操作细节。确定了1277个代码锈蚀。从订购X射线到最终放射学报告的平均时间为50分钟,总计$2,362,450.00花费在手术室时间上。在紧急或紧急情况下,CodeRust的调用频率是其两倍,与选修相比。与非CodeRust房间相比,CodeRust房间的工作人员更多。在42/1277(3.3%)例中,在X射线上发现了异物。CodeRust是一个资源密集型过程,在涉及多名员工的紧急情况下更为常见。虽然在一小部分病例中发现了残留的异物,应该重新审视当前的系统,以减少运行时间和费用。
    At Cleveland clinic, an incorrect surgical count triggers Code Rust; a protocol that mandates an intraoperative patient X-ray, staff radiology read, and discussion with the surgeon before the incision is closed. Code Rust calls from November 2014 to December 2022 were retrospectively reviewed. Realtime workflow and operative details of Code Rust cases were analyzed.1277 Code Rusts were identified. Average time from ordering the X-ray to final radiology report was 50 minutes, totalling $2,362,450.00 spent on operating room time. Code Rust was called twice as frequently during urgent or emergent cases, compared to elective. There were more staff in Code Rust rooms compared to non-Code Rust rooms. A foreign body on X-ray was identified in 42/1277 (3.3%) cases. Code Rust is a resource intensive process that is more common in emergent cases that involve multiple staff. While retained foreign bodies are identified in a small percentage of cases, the current system should be revisited to reduce operating time and expense.

    医疗保健绩效指标主要是根据结果提供的,进程,或医疗保健服务的结构组成部分。然而,测量受到数据源可变性的限制,定义,和解决方法。美国外科医生学院最近开发了一种新型的绩效指标,称为“程序措施”。这些指标对齐结构,进程,和结果,以便在一线护理团队的支持下更好地协调质量测量。以这种多方面的方式,这些措施不同于目前的“单一”措施,如针对手术部位感染。这些措施的主题重点以及结构资源组成部分的协调以支持进程和成果,也使这些措施与当代综合措施区分开来。重要的是,这些措施的结构要素反映了患者护理所需的最低资源,解决当地机构在解决许多现有质量指标时感受到的人员和资源障碍。这些指标将简化质量报告,以改善患者的护理导航。临床医生会发现更适当的目标和责任,从而增加团队合作和沟通。这些措施旨在解决当前指标过剩的负担,优先级错位,以及以患者为中心的低资源,以更好地调整医疗保健质量和测量。
    Health care performance metrics are offered predominantly in terms of outcomes, processes, or structural components of health care delivery. However, measurement is limited by variability in data sources, definitions, and workarounds. The American College of Surgeons has recently developed a new type of performance metric known as a \"programmatic measure\". These metrics align structures, processes, and outcomes to better coordinate quality measurement with support of frontline care teams. In this multifaceted way, these measures differ from current \"single\" measures such as targeting surgical site infection. The thematic focus of these measures and alignment of structure-resource components to support processes and outcomes also sets these measures apart from contemporary composite measures. Importantly, structural elements of these measures reflect minimum resources required for patient care, addressing staffing and resource barriers felt by local institutions in addressing numerous existing quality metrics. These metrics will streamline quality reporting to improve care navigation for patients. Clinicians will find more appropriately aligned goals and responsibilities, resulting in increased teamwork and communication. These measures are designed to address the current burdens of overabundant metrics, priority misalignment, and low resources in a patient-centric fashion to better align health care quality and measurement.

    目标:累积,基于概率的指标经常被用来衡量职业体育的质量,但这些方法尚未应用于医疗保健服务。这些技术有可能在描述手术质量方面特别有用,其中病例量是可变的,结果往往受统计“噪声”支配。已建立的统计技术用于调整案件数量的差异是可靠性调整,强调统计“信号”,但有几个局限性。我们试图验证一种基于结果方法的手术质量的新衡量标准(死亡率高于平均水平,DAA)对照可靠性调整后的死亡率,使用腹主动脉瘤(AAA)修复结果来说明该措施的性能。
    方法:使用挣得结果方法计算每位患者的关注结果:高于平均水平的死亡(DAA)。从2016-2019年,在血管质量倡议(VQI)数据库中计算了未破裂的开放式AAA修复和EVAR的医院级DAA。每个中心的DAA是每个患者的观察到的预测死亡风险的总和;使用建立的多变量逻辑回归模型计算预测死亡风险。确定了DAA与可靠性调整后的死亡率和手术量的相关性。因为准确的质量指标应该与未来的结果相关,2016-2017年的结局用于根据(1)风险调整后的死亡率对医院质量进行分类,(2)风险和可靠性调整后的死亡率,(3)DAA。通过比较这些类别预测2018-2019年风险调整结果的能力,确定了最佳表现的质量指标。
    结果:在研究期间,3,734名患者接受了开放式修复(106家医院),20,680名患者接受了EVAR(183家医院)。DAA与开放修复(r=0.94,P<0.001)和EVAR(r=0.99,P<0.001)的可靠性校正死亡率密切相关。DAA也与开放修复的医院病例量相关(r=-.54,P<0.001)。而不是EVAR(r=0.07,P=0.3)。2016-2017年,大多数医院的死亡率为0%(55%的开放式修复,57%EVAR),无法仅使用传统的风险调整后死亡率来评估这些医院。Further,2016-2017年的零死亡率医院在2018-2019年的开放式修复没有表现出改善的结果(3.8%vs4.6%,P=0.5)或EVAR(0.8%对1.0%,与所有其他医院相比,P=0.2)。与传统的风险调整相比,2016-2017年DAA将中心平均划分为质量四分位数,预测2018-2019年的表现与质量四分位数的每一次下降相关的死亡率增加(Q13.2%,第二季度4.0%,第三季度5.1%,第四季度6.0%)。与最佳四分位数医院相比,最差四分位数开放式修复医院的死亡风险明显更高(OR2.01,[95%CI1.07-3.76],P=0.03)。使用2016-2019年DAA定义质量,与质量最低的四分位数医院相比,最高质量的四分位数开放式维修医院的中位数DAA较低(-1.18DAAvs+1.32DAA,P<0.001),与较低的中位可靠性调整死亡率相关(3.6%vs5.1%,P<0.001)。
    结论:在衡量医院水平结果时,调整医院容量的差异至关重要。获得的结果可以准确地对医院质量进行分类,并与可靠性调整相关,但更易于计算和解释。从2016年至2019年,与普通医院相比,最高质量的开放式AAA修复医院预防了>40例围手术期死亡。与质量最低的医院相比,围手术期死亡>80例。
    OBJECTIVE: Cumulative, probability-based metrics are regularly used to measure quality in professional sports, but these methods have not been applied to health care delivery. These techniques have the potential to be particularly useful in describing surgical quality, where case volume is variable and outcomes tend to be dominated by statistical \"noise.\" The established statistical technique used to adjust for differences in case volume is reliability-adjustment, which emphasizes statistical \"signal\" but has several limitations. We sought to validate a novel measure of surgical quality based on earned outcomes methods (deaths above average [DAA]) against reliability-adjusted mortality rates, using abdominal aortic aneurysm (AAA) repair outcomes to illustrate the measure\'s performance.
    METHODS: Earned outcomes methods were used to calculate the outcome of interest for each patient: DAA. Hospital-level DAA was calculated for non-ruptured open AAA repair and endovascular aortic repair (EVAR) in the Vascular Quality Initiative database from 2016 to 2019. DAA for each center is the sum of observed - predicted risk of death for each patient; predicted risk of death was calculated using established multivariable logistic regression modeling. Correlations of DAA with reliability-adjusted mortality rates and procedure volume were determined. Because an accurate quality metric should correlate with future results, outcomes from 2016 to 2017 were used to categorize hospital quality based on: (1) risk-adjusted mortality; (2) risk- and reliability-adjusted mortality; and (3) DAA. The best performing quality metric was determined by comparing the ability of these categories to predict 2018 to 2019 risk-adjusted outcomes.
    RESULTS: During the study period, 3734 patients underwent open repair (106 hospitals), and 20,680 patients underwent EVAR (183 hospitals). DAA was closely correlated with reliability-adjusted mortality rates for open repair (r = 0.94; P < .001) and EVAR (r = 0.99; P < .001). DAA also correlated with hospital case volume for open repair (r = -.54; P < .001), but not EVAR (r = 0.07; P = .3). In 2016 to 2017, most hospitals had 0% mortality (55% open repair, 57% EVAR), making it impossible to evaluate these hospitals using traditional risk-adjusted mortality rates alone. Further, zero mortality hospitals in 2016 to 2017 did not demonstrate improved outcomes in 2018 to 2019 for open repair (3.8% vs 4.6%; P = .5) or EVAR (0.8% vs 1.0%; P = .2) compared with all other hospitals. In contrast to traditional risk-adjustment, 2016 to 2017 DAA evenly divided centers into quality quartiles that predicted 2018 to 2019 performance with increased mortality rate associated with each decrement in quality quartile (Q1, 3.2%; Q2, 4.0%; Q3, 5.1%; Q4, 6.0%). There was a significantly higher risk of mortality at worst quartile open repair hospitals compared with best quartile hospitals (odds ratio, 2.01; 95% confidence interval, 1.07-3.76; P = .03). Using 2016 to 2019 DAA to define quality, highest quality quartile open repair hospitals had lower median DAA compared with lowest quality quartile hospitals (-1.18 DAA vs +1.32 DAA; P < .001), correlating with lower median reliability-adjusted mortality rates (3.6% vs 5.1%; P < .001).
    CONCLUSIONS: Adjustment for differences in hospital volume is essential when measuring hospital-level outcomes. Earned outcomes accurately categorize hospital quality and correlate with reliability-adjustment but are easier to calculate and interpret. From 2016 to 2019, highest quality open AAA repair hospitals prevented >40 perioperative deaths compared with the average hospital, and >80 perioperative deaths compared with lowest quality hospitals.
