The volume-outcomes relationship in donation after circulatory death liver transplantation.

BACKGROUND: Donation after circulatory death (DCD) liver transplantation (LT) has become an effective mechanism for expanding the donor pool and decreasing waitlist mortality. However, it is unclear if low-volume DCD centers can achieve comparable outcomes to high-volume centers. METHODS: From 2011 to 2019 utilizing the United Network for Organ Sharing (UNOS) database, liver transplant centers were categorized into tertiles based on their annual volume of DCD LTs. Donor selection, recipient selection, and survival outcomes were compared between very-low volume (VLV, n = 1-2 DCD LTs per year), low-volume (LV, n = 3-5), and high-volume (HV, n > 5) centers. RESULTS: One hundred and ten centers performed 3273 DCD LTs. VLV-centers performed 339 (10.4%), LV-centers performed 627 (19.2%), and HV-centers performed 2307 (70.4%) LTs. 30-day, 90-day, and 1-year patient and graft survival were significantly increased at HV-centers (all P < .05). Recipients at HV-centers had shorter waitlist durations (P < .01) and shorter hospital lengths of stay (P < .01). On multivariable regression, undergoing DCD LT at a VLV-center or LV-center was associated with increased 1-year patient mortality (VLV-OR:1.73, 1.12-2.69) (LV-OR: 1.42, 1.01-2.00) and 1-year graft failure (VLV-OR: 1.79, 1.24-2.58) (LV-OR: 1.28, .95-1.72). DISCUSSION: Increased annual DCD liver transplant volume is associated with improved patient and graft survival.

The Impact of a Comprehensive Resident Curriculum and Required Participation in "This Week in SCORE" on General Surgery ABSITE Performance and Well-Being.

OBJECTIVE: This Week in SCORE (TWIS) is a biennial, general surgery curriculum comprised of weekly online modules, readings, and multiple-choice quizzes. In this study, we examined the impact of required TWIS on American Board of Surgery In-Training Examination (ABSITE) scores and well-being among categorical general surgery residents. DESIGN, SETTING, AND PARTICIPANTS: TWIS quiz completion became required in 2017. Residents attended weekly lectures, and ABSITE performance was incentivized with educational stipends. Surveys were distributed to assess study preferences, learning styles, burnout, and grit. Thirty-six categorical general surgery residents who took ABSITE in both 2017 and 2018 were evaluated in a paired-sample, retrospective analysis. RESULTS: After requiring TWIS, median ABSITE percentile increased by 12% (65%-77%, p = 0.001). Weekly TWIS completion (59% vs 89%, p < 0.001) and quiz results (62% vs 69%, p = 0.005) also improved. During this time, emotional exhaustion and depersonalization declined significantly, yet overall burnout scores did not change. Of 21 survey respondents, 66.7% (n = 14) increased weekly study time by a median of 2.5 hours. However, less than half used Surgical Council on Resident Education as their primary study tool. Only 23.8% (n = 5) reported that mandatory TWIS modified their study behavior, while 90.4% (n = 19) felt the culture of education had improved. CONCLUSIONS: After TWIS participation became required, ABSITE performances improved. Formalized curriculum with frequent assessment may foster accountability among residents, enhancing educational climate, well-being, and test performance.
