Outcome of transplantation performed outside the regular working hours: A systematic review and meta-analysis of the literature

Journal Contribution - Review Article

Transplant procedures are frequently performed outside the regular working hours (after hours). In general surgery, several studies observed worse outcomes for operations performed after hours. The predetermined hypothesis was that patients undergoing transplantation during after hours might suffer from an excess in postoperative mortality and morbidity when compared to patients undergoing transplantations during the regular working hours. A systematic review of the PubMed database identified 11,993 records, of which eleven cohort studies including a total of 287,741 patients investigated the association between the starting time of transplant surgery and postoperative mortality (primary outcome) and/or morbidity (secondary outcome). Eight studies evaluated kidney transplants (in 165,277 patients), two studies analyzed liver transplants (in 95,346 patients), and one study investigated transplantations of thoracic organs (in 27,118 patients). Results were conflicting with two studies (in liver and lung transplantation) showing an increased mortality for transplantations performed after hours, and five studies showing no effects on mortality. A meta-analysis on estimates from four studies yielded a hazard ratio of 1.01 (95% CI, 0.98 to 1.04) for mortality comparing transplantations performed during versus outside the regular working hours. The evidence was also inconclusive for a variety of morbidity outcomes with studies demonstrating either a deterioration of outcome, no effect or an improved outcome for after hours procedures. On the basis of the available evidence, it appears impossible to give an unequivocal recommendation regarding starting times in transplant surgery. (C) 2018 Elsevier Inc. All rights reserved.
