g. HGG) and non-REDs (e. g. recurrent cholangitis). While

prior work has demonstrated regional variation in the use of exceptions, no work has examined the between-center variability in the use, and subsequent approval, of non-RED exceptions. We analyzed all new waitlist candidates from 2/27/02-6/3/11, to explore variation in the use of non-REDs, for which no strict exception criteria exist. Of 58, 641 new waitlist candidates, 4, 356 (7. 4%) applied for a non-RED exception. The number of applications increased over time, as did the approval rates for such applications—nearly MK-2206 clinical trial 50% in 2002 to 75% in 2010.Adjusting for patient factors, there was significant variability (P<0.001) in the use of non-RED exceptions in 7/11 UNOS regions, and in the approval of these exceptions in 6/11しNOS regions. In 3 しNOS regions, the absolute difference in the adjusted proportion of approved non-RED exceptions between centers with the highest and lowest approval rates was >30%. Variability

learn more in the use and approval of non-REDs was clinically significant—waitlist candidates with approved exceptions were significantly more likely to be transplanted (68. 3% vs. 53. 4%, P<0.001) and less likely to be removed for death or clinical deterioration (10.4% vs. 16. 2%, P<0.001). While increased median MELD at transplantation within a donor service area was associated with increased odds of applying for exceptions, no other center factors were associated with applying for, or having non-RED exceptions approved.

Goldberg, George A. Makar, Benjamin French Background: With the aging of the HCV cohort and increasing prevalence of NAFLD, the burden on primary care providers (PGPs) to care for patients with chronic liver disease and cirrhosis is growing nationwide. In response to this problem, the Veterans Health Administration implemented a series of innovative initiatives focusing on primary care-specialty referral to increase PGP competency in the management of complex chronic medical diseases. One such initiative, the SGAN-EGHO program, was implemented in mid-2011 to transfer subspecialfy knowledge to primary care providers through case-based distance learning combined with real-time consultation. Although this program has now been implemented widely, there is limited information regarding its ability to engage PGPs to learn and influence their clinical practice. Aims: We surveyed primary care providers in order to assess the factors which led to their participation in the SCAN-ECHO program and the educational impact of their participation. Results: Out of 51 potential provider participants, 24 responded to an anonymous web-based survey.
