基于MELD的死亡供体肝脏分配允许评分可能无法反映其真实死亡风险的患者例外。我们假设OPO可能在例外做法上有所不同,例外的使用可能会随着时间的推移而增加,并且例外患者可能会相对于其他患者而被忽视。我们分析了2002 - 2010年向UNOS报告的88,981例成人肝脏候选者的纵向MELD评分、例外和结局。接受HCC例外的患者比例在OPO水平为0-21.4%,在区域水平为11.9-18.8%;其他情况例外的比例为0.0%-13.1%(OPO级)和3.7%-9.5%总部合同委员会的例外情况随着时间的推移而增加(2002年为10.5%,2008年为15.5%,HR=1.09/年,p<0.001),其他例外情况也是如此(2002年7.0%对比2008年13.5%,HR=1.11,p<0.001)。(自2005年4月起),与非肝癌患者相比,肝癌患者和其他例外患者的等待名单死亡风险降低。具有同等列表优先级的例外患者(多项逻辑回归OR=0.47 HCC,OR=0.43其他,p<0.001)和移植几率增加(HCC的OR=1.65,其他的OR=1.33,p<0.001)。政策优势MELD例外的患者; OPO的不同例外率可能会产生或反映地理不平等。
MELD-based allocation of deceased donor livers allows exceptions for patients whose score may not reflect their true mortality risk. We hypothesized that OPOs may differ in exception practices, use of exceptions may be increasing over time, and exception patients may be advantaged relative to other patients. We analyzed longitudinal MELD score, exception, and outcome in 88,981 adult liver candidates as reported to UNOS from2002–2010.Proportion of patients receiving an HCC exception was 0–21.4% at the OPO-level and 11.9–18.8% at the region-level; proportion receiving an exception for other conditions was 0.0%–13.1% (OPO-level) and 3.7%–9.5%% (region-level).HCC exceptions rose over time (10.5% in 2002 vs. 15.5% in 2008, HR=1.09 per year, p<0.001) as did other exceptions (7.0% in 2002 vs. 13.5% in 2008, HR=1.11, p<0.001).In the most recent era of HCC point assignment (since April 2005), both HCC and other exceptions were associated with decreased risk of waitlist mortality compared to non-exception patients with equivalent listing priority (multinomial logistic regression OR=0.47 for HCC, OR=0.43 for other, p<0.001) and increased odds of transplant (OR=1.65 for HCC, OR=1.33 for other, p<0.001).Policy advantages patients with MELD exceptions;differing rates of exceptions by OPO may create, or reflect, geographic inequity.
