Research priorities in liver transplant anesthesiology: Results of a survey of liver transplant anesthesiologists.

Optimal perioperative care contributes to improved patient outcomes, as demonstrated in the field of liver transplant (LT). The evolution in perioperative care over the past two decades has been driven by research in areas such as preoperative testing, coagulation management, and intraoperative monitoring. However, much of this research is driven by local institutional pressures and practices with a dearth of studies emanating from research consortia or other groups of experts within the field. To better characterize the top research questions in the field, we queried a group of 128 LT anesthesiologists representing 87 international liver transplant centers with a response from 71 practitioners (59.2%). Three experts then codified the responses into the top 20 questions, which were sent to the survey recipients as a second survey to rank order. Seventy-five respondents (61.5%) provided responses, which were merged into a weighted ranked priority list and analyzed by respondent location and center size. The highest ranked question was, "What intraoperative anesthetic management/interventions affect graft outcome?" Most of the top research questions focused on preoperative risk factor management or optimization and intraoperative management techniques. In general, this priorities list may serve as a guide for transplant anesthesiology researchers to focus future research endeavors on shared interests that improve patient care.
