项目摘要

PROJECT SUMMARY Alcohol-associated liver disease (ALD), which includes alcohol-associated cirrhosis (AAC) and alcohol- associated hepatitis (AH), is now the leading indication for liver transplant (LT) in the US. Early LT (eLT), defined as LT evaluation with <6 months of alcohol abstinence, is associated with acceptable outcomes for AH in retrospective studies. However, prospective, multi-center data including biopsychosocial factors on eLT for all advanced ALD in racially, culturally, and socioeconomically diverse populations are lacking. It is known that alcohol cessation is the most important factor influencing survival in ALD, and integrated alcohol use disorder (AUD)/ALD care is critical to help patients achieve abstinence, yet the degree of care integration and how this influences post-LT outcomes has not been systematically studied. Knowledge gaps in eLT for ALD include: a) limited data on who gets referred for eLT and referral barriers; b) lack of standardized biopsychosocial measures and outcomes; and c) minimal stakeholder involvement beyond LT providers. There is an urgent need to (1) define factors influencing eLT referral, (2) develop risk prediction models of key patient-centered outcomes, (3) incorporate validated biopsychosocial measures into models, and (4) evaluate the impact of integrated care on outcomes following eLT. For example, The INTEGRATE collaborative, comprised of diverse, multidisciplinary clinicians and researchers from the University of Texas Southwestern Medical Center, University of Michigan, University of Miami, and Columbia University-Weill Cornell Medicine, is ideally positioned to address these urgent research needs. Collectively, we have developed a distinctive investigator team with diversity in: (1) career stage (2) sex and race/ethnicity, (3) clinical and methodological expertise in ALD, AUD, LT, behavioral research, risk modeling, data harmonization, health disparities, causal inference, and mixed-methods research, and (4) documented track record of NIH funding in LT access, organ allocation, LT outcomes and healthcare disparities, and NIAAA funding in ALD/AUD. Our large volume transplant centers with established protocols for eLT for ALD applied to highly diverse populations will facilitate the following aims: 1) characterize and develop risk prediction models for transplant-free survival among those with limited access to LT to define those in greatest need of eLT referral and listing; 2) evaluate barriers and facilitators to referral for eLT in ALD; 3) apply causal inference approaches to observational data to evaluate biopsychosocial factors and develop risk models predictive of outcomes at key timepoints in eLT for ALD; 4) define stakeholder perceptions and preferences for selection and outcomes in eLT for ALD; and 5) evaluate how integrated care processes influence outcomes in eLT for ALD. At the conclusion of this work, we will have collaboratively: (1) defined factors for referral and waitlisting for eLT in ALD (selection), (2) identified which biopsychosocial factors are causally related and predictive of outcomes most important to stakeholders (outcomes) and (3) determined how integrated care influences stakeholder-relevant outcomes in eLT for ALD (management).

项目摘要酒精相关性肝病（ALD），包括酒精相关性肝硬化（AAC）和酒精相关性肝硬化。相关肝炎（AH），现在是美国肝移植（LT）的主要适应症。早期LT（eLT），定义为戒酒<6个月的LT评估，与AH的可接受结局相关在回顾性研究中。然而，前瞻性多中心数据，包括eLT的生物心理社会因素，在种族、文化和社会经济多样化的人群中缺乏所有晚期ALD。已知的是戒酒是影响ALD患者生存率的最重要因素， (AUD)/ALD护理对于帮助患者实现禁欲至关重要，但护理整合的程度以及如何实现这一目标，对LT后结局的影响尚未进行系统研究。在用于ALD的电子LT方面的知识差距包括：关于谁被转诊接受eLT和转诊障碍的数据有限; B）缺乏标准化的生物心理社会措施和成果;以及c）除长期培训提供者外，利益攸关方的参与最少。目前迫切需要（1）确定影响eLT转诊的因素，（2）开发以关键患者为中心的风险预测模型，结果，（3）将有效的生物心理社会措施纳入模型，（4）评估 eLT后的综合治疗结果。例如，INTEGRATE协作组织，由来自德克萨斯大学西南医学中心的多元化、多学科的临床医生和研究人员，密歇根大学、迈阿密大学和哥伦比亚大学-威尔康奈尔医学院是理想的以满足这些迫切的研究需求。总的来说，我们培养了一个与众不同的调查员团队在以下方面具有多样性：（1）职业阶段（2）性别和种族/民族，（3）临床和方法学专业知识， ALD，AUD，LT，行为研究，风险建模，数据协调，健康差异，因果推断，和混合方法研究，以及（4）记录NIH在LT获取，器官分配， LT结果和医疗差异，以及ALD/AUD中的NIAAA资金。我们的大型移植中心将已建立的用于ALD的eLT方案应用于高度多样化的人群将有助于实现以下目标： 1)描述和开发风险预测模型，用于在获得机会有限的患者中实现无移植生存以确定最需要eLT转诊和列名的人; 2）评估转诊的障碍和促进因素 3）将因果推理方法应用于观察数据，以评估生物心理社会因素并开发风险模型，预测ALD eLT关键时间点的结果; 4）定义利益相关者对ALD eLT选择和结局的看法和偏好;以及5）评估综合护理如何过程影响ALD的eLT结果。在这项工作结束时，我们将合作：（1）确定ALD中转诊和等待eLT的因素（选择），（2）确定哪些生物心理社会因素因素是因果相关的，并预测对利益相关者最重要的结果（结果）和（3）确定了综合护理如何影响ALD（管理）eLT中的患者相关结局。
