['Smoking is a modifiable risk factor for cardiovascular disease, malignancy, and surgical complications. Transplant center practices toward smokers vary widely and evoke the classic tension between the ethical principles of justice and utility. We sought to assess current smoking policy variation in U.S. kidney, liver, and pancreas transplant centers.', 'An online survey was sent to program directors of all United Network for Organ Sharing-approved solid abdominal organ transplant programs regarding their policies toward prior and current tobacco use.', 'Responses were received from 26% of kidney, 31% of liver, and 37% of pancreas transplant centers. Across organ programs, virtually all centers (97% to 100%) reported transplantations for former smokers, whereas 59% of kidney, 62% of liver, and 33% of pancreas programs reported transplantations for current smokers. Organ programs reported similar rates of having smoking cessation programs (74% to 77%) and performing serum cotinine testing (31% to 38%). Smoking was an absolute contraindication to transplantation at 38% of kidney, 15% of liver, and 50% of pancreas programs. Programs with absolute contraindication policies were less likely to perform transplantations in current smokers and more likely to check serum cotinine levels, but no more likely to have smoking cessation programs.'] Do abdominal Organ Transplant Center Tobacco Use Policies Vary by Organ Program Type?
