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.
