The study population consisted of 221 patients at risk for ongoing abdominal infection. The following scoring systems were evaluated with logistic regression analysis for their ability to select patients requiring a relaparotomy: APACHE-II score, SAPS-II, Mannheim Peritonitis Index (MPI), MODS, SOFA score, and the acute part of the APACHE-II score (APS).The proportion of patients requiring a relaparotomy was 32% (71/221). Only 2 scores had a discriminatory ability in identifying patients with ongoing infection needing relaparotomy above chance: the APS on day 1 (AUC 0.61; 95%CI 0.52-0.69) and the SOFA score on day 2 (AUC 0.60; 95%CI 0.52-0.69). However, to correctly identify 90% of all patients needing a relaparotomy would require such a low cut-off value that around 80% of all patients identified by these scoring systems would have negative findings at relaparotomy.None of the widely-used scoring systems to predict overall outcome in critically ill patients are of clinical value for the identification of patients with ongoing infection needing relaparotomy. There is a need to develop more specific tools to assist physicians in their daily monitoring and selection of these patients after the initial emergency laparotomy.ISRCTN: ISRCTN 51729393Our group conducted a trial among patients with abdominal sepsis comparing on-demand versus planned relaparotomy after the initial emergency operation (RELAP trial) [1]. We concluded that the on-demand strategy should be preferred, based on comparable clinical outcomes (12-month mortality 29% vs. 36%; P = 0.22), but a substantial reduction of healthcare utilization and costs [1]. Planned relaparotomy yielded negative findings in 66% of patients and, thus, had no therapeutic effect in these patients. Improvement of patient selection for relaparotomy in the on-demand strategy however is necessary as 31% of these patients also had a negative relaparotomy [1].The on-demand %U http://www.biomedcentral.com/1471-2482/11/38
