Synopsis
Trial design is the biggest problem with Evidence Based Medicine in the Intensive Care Unit. Paul Young wants to change that paradigm completely. He argues for research as we know it to change and to focus on clinical care with systemised and optimised treatments that reliably improves outcomes over time for all patients. Mortality measured at a particular time point (landmark mortality) is often regarded as the gold standard outcome for randomised controlled trials in Intensive Care Medicine. An important limitation of many Intensive Care Medicine trials is that they hypothesize large and potentially implausible reductions in absolute mortality. This is a major problem in trial design for two reasons. Firstly, it makes false negative trial results more likely. Secondly, the less plausible a postulated mortality reduction is the more likely that a statistically significant mortality difference will represent a false positive. This is because a p-value is defined as the probability of finding a result equal to
