Hepatocellular carcinoma (HCC) is a leading cause of morbidity and mortality in cirrhosis patients. This provides an opportunity to target the highest-risk population, yet surveillance rates in the United States and Europe range from 10% to 40%. The goal of this study was to identify barriers to HCC surveillance, using data from the Veterans Health Administration, the largest provider of liver-related health care in the United States. We included all patients 75 years of age or younger who were diagnosed with cirrhosis from January 1, 2008, until December 31, 2010. The primary outcome was a continuous measure of the percentage of time up-to-date with HCC surveillance (PTUDS) based on abdominal ultrasound (secondary outcomes included computed tomography and magnetic resonance imaging). Among 26,577 patients with cirrhosis (median follow-up = 4.7 years), the mean PTUDS was 17.8 ± 21.5% (ultrasounds) and 23.3 ± 24.1% when any liver imaging modality was included. The strongest predictor of increased PTUDS was the number of visits to a specialist (gastroenterologist/hepatologist and/or infectious diseases) in the first year after cirrhosis diagnosis; the association between visits to a primary care physician and increasing surveillance was very small. Increasing distance to the closest Veterans Administration center was associated with decreased PTUDS. There was an inverse association between ultrasound lead time (difference between the date an ultrasound was ordered and requested exam date) and the odds of it being performed: odds ratio = 0.77, 95% confidence interval 0.72-0.82 when ordered > 180 days ahead of time; odds ratio = 0.90, 95% confidence interval 0.85-0.94 if lead time 91-180 days.
The responsibility for suboptimal surveillance rests with patients, providers, and the overall health care system; several measures can be implemented to potentially increase HCC surveillance, including increasing patient-specialist visits and minimizing appointment lead time.

肝细胞癌(HCC)是肝硬化患者发病率和死亡率的主要原因。这为靶向高危人群提供了机会,但美国和欧洲的监测率在 10%至 40%之间。本研究的目的是利用美国最大的肝脏相关医疗保健服务提供商退伍军人健康管理局的数据,确定 HCC 监测的障碍。我们纳入了 2008 年 1 月 1 日至 2010 年 12 月 31 日期间诊断为肝硬化的所有 75 岁以下患者。主要结局是基于腹部超声(次要结局包括计算机断层扫描和磁共振成像)的 HCC 监测时间百分比(PTUDS)的连续测量。在 26577 例肝硬化患者(中位随访时间为 4.7 年)中,PTUDS 的平均值为 17.8%±21.5%(超声),当纳入任何肝脏成像方式时,PTUDS 的平均值为 23.3%±24.1%。PTUDS 增加的最强预测因子是肝硬化诊断后第一年就诊专家(胃肠病学家/肝病学家和/或传染病学家)的次数;就诊初级保健医生与增加监测之间的关联非常小。距离最近的退伍军人管理局中心的距离增加与 PTUDS 降低相关。超声提前时间(下达超声检查命令与请求检查日期之间的差异)与进行超声检查的可能性呈反比:提前 180 天以上下达命令时的比值比为 0.77(95%置信区间 0.72-0.82);提前 91-180 天时比值比为 0.90(95%置信区间 0.85-0.94)。
监测不佳的责任在于患者、提供者和整个医疗保健系统;可以采取一些措施来提高 HCC 监测率,包括增加患者与专家的就诊次数和尽量减少预约提前时间。
