To expand the donor liver pool, ways are sought to better define the limits of marginally transplantable organs. The Donor Risk Index (DRI) lists 7 donor characteristics, together with cold ischemia time and location of the donor, as risk factors for graft failure. We hypothesized that donor hepatic steatosis is an additional independent risk factor. We analyzed the Scientific Registry of Transplant Recipients for all adult liver transplants performed from October 1, 2003, through February 6, 2008, with grafts from deceased donors to identify donor characteristics and procurement logistics parameters predictive of decreased graft survival. A proportional hazard model of donor variables, including percent steatosis from higher-risk donors, was created with graft survival as the primary outcome. Of 21,777 transplants, 5051 donors had percent macrovesicular steatosis recorded on donor liver biopsy. Compared to the 16,726 donors with no recorded liver biopsy, the donors with biopsied livers had a higher DRI, were older and more obese, and a higher percentage died from anoxia or stroke than from head trauma. The donors whose livers were biopsied became our study group. Factors most strongly associated with graft failure at 1 year after transplantation with livers from this high-risk donor group were donor age, donor liver macrovesicular steatosis, cold ischemia time, and donation after cardiac death status. In conclusion, in a high-risk donor group, macrovesicular steatosis is an independent risk factor for graft survival, along with other factors of the DRI including donor age, donor race, donation after cardiac death status, and cold ischemia time. As attempts have been made to expand the donor pool, defining the limitations of marginal organs for liver transplantation has become more refined and more critical. Many investigators have examined the variables associated with patient and graft outcome after liver transplantation. The variables can be categorized into: donor factors, procurement logistics, recipient factors, and operative factors. Having a clear understanding of the donor factors and procurement logistics factors can improve recipient selection, organ allocation, and potentially patient and graft survival.The Donor Risk Index (DRI) developed in 2006 by Feng et al. 29 contains 7 donor and 2 procurement characteristics (including cold ischemia time [CIT]) that predict an increased risk of graft failure. The objective and quantitative nature of the DRI enables frank discussion between transplant staff and potential recipients regarding the risks involved with prospective donor organs. Importantly, the factors required to determine the DRI are known, and the CIT can be estimated at the time of the organ offer, allowing responsible assessment by transplant staff and Abbreviations: DRI, Donor Risk
Our objectives are to report patient characteristics, comorbidities, and outcomes for gastroschisis patients and analyze factors associated with mortality and sepsis. Using Pediatric Health Information System data, we examined neonates with both an International Classification of Diseases, 9th Revision diagnosis (756.79) and procedure (54.71) code for gastroschisis (2003 to 2008). We examined descriptive characteristics and conducted multivariate regression models examining risk factors for mortality, during the birth hospitalization, and sepsis. Analysis of 2490 neonates with gastroschisis found 90 deaths (3.6%) and sepsis in 766 (31%). Critical comorbidities and procedures are cardiovascular defects (15%), pulmonary conditions (5%), intestinal atresia (11%), intestinal resection (12.5%), and ostomy formation (8.3%). Factors associated with mortality were large bowel resection (odds ratio [OR] 8.26, 95% confidence interval [CI] 1.17 to 58.17), congenital circulatory (OR 5.62, 95% CI 2.11 to 14.91), and pulmonary (OR 8.22, 95% CI 2.75 to 24.58) disease, and sepsis (OR 3.87, 95% CI 1.51 to 9.91). Factors associated with sepsis include intestinal ostomy (OR 2.94, 95% CI 1.71 to 5.05), respiratory failure (OR 2.48, 95% CI 1.85 to 3.34), congenital circulatory anomalies (OR 1.58, 95% CI 1.10 to 2.28), and necrotizing enterocolitis (OR 4.38, 95% CI 2.51 to 7.67). Further investigation into modifiable factors such as small bowel ostomy and prevention of sepsis and necrotizing enterocolitis is warranted to guide surgical decision making and postoperative management.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
