The American Association for the Study of Liver Disease (AASLD) recommends screening for esophageal varices (EV) by esophagoduodenoscopy (EGD) in patients with cirrhosis to guide decisions regarding primary prophylaxis for EV hemorrhage. We aimed to identify patient and facility factors associated with EV screening in veterans with hepatitis C (HCV)-associated cirrhosis.
This was a population-based cohort study. Veterans with HCV and newly diagnosed cirrhosis between 1/1/2004 and 12/31/2005 and followed until 12/31/2011 were included. The primary outcome was receipt of EGD within 1 year of cirrhosis diagnosis. Patient- and facility-level factors associated with EV screening were determined.
A total of 4230 patients with HCV cirrhosis were identified. During median follow-up of 6.1 years (IQR: 4.0-8.0), 21.5 % developed a decompensating event, and 38.3 % died. Fifty-four percent received an EGD, and 33.8 % had an EGD within guidelines. Median time from cirrhosis diagnosis to EGD was 72 days (IQR: 12-176). Factors independently associated with receipt of EV screening were a decompensation event (OR 1.16, CI 1.01-1.32) and gastroenterology/hepatology clinic access (OR 2.1, CI 1.73-2.46), whereas cardiovascular (OR 0.81, CI 0.69-0.95), mental health (OR 0.79, CI 0.68-0.91), and respiratory (OR 0.85, CI 0.72-0.99) comorbidities were associated with reduced likelihood of EV screening.
EV screening per AASLD guidelines occurs in only one-third of patients. This missed opportunity was strongly associated with access to gastroenterology/hepatology specialty care. Additionally, providers may be relying on clinical cues (i.e., decompensation) to prompt referral for endoscopy suggesting education to improve compliance with guidelines is needed.
美国肝病研究协会(AASLD)建议对肝硬化患者进行食管十二指肠镜检查(EGD)以筛查食管静脉曲张(EV),从而指导关于EV出血一级预防的决策。我们旨在确定丙型肝炎(HCV)相关肝硬化退伍军人中与EV筛查相关的患者和机构因素。
这是一项基于人群的队列研究。纳入2004年1月1日至2005年12月31日期间新诊断为HCV且患有肝硬化并随访至2011年12月31日的退伍军人。主要结局是在肝硬化诊断后1年内接受EGD检查。确定了与EV筛查相关的患者和机构层面因素。
共确定了4230例HCV肝硬化患者。在中位随访6.1年(四分位间距:4.0 - 8.0)期间,21.5%发生失代偿事件,38.3%死亡。54%接受了EGD检查,33.8%在指南规定时间内接受了EGD检查。从肝硬化诊断到EGD检查的中位时间为72天(四分位间距:12 - 176)。与接受EV筛查独立相关的因素是失代偿事件(比值比1.16,可信区间1.01 - 1.32)和可就诊于胃肠病学/肝病学诊所(比值比2.1,可信区间1.73 - 2.46),而心血管疾病(比值比0.81,可信区间0.69 - 0.95)、心理健康问题(比值比0.79,可信区间0.68 - 0.91)和呼吸系统疾病(比值比0.85,可信区间0.72 - 0.99)合并症与EV筛查可能性降低相关。
按照AASLD指南进行的EV筛查仅在三分之一的患者中进行。这种错失的机会与获得胃肠病学/肝病学专科护理密切相关。此外,医疗服务提供者可能依赖临床提示(即失代偿)来促使进行内镜检查转诊,这表明需要开展教育以提高对指南的依从性。
