Data from meta-analyses has suggested harm related to albumin therapy in critically ill patients and new observational data are consistent with these results. However appropriately powered randomized controlled trials have shown albumin to be safe in broad groups of critically ill patients. This article will discuss the reasons for differences between observational and controlled trial data and the implications for future albumin use and clinical research. Introduction The interpretation of clinical trial data is the cornerstone of both evidence-based medicine and medical practice 1 2 . The level of evidence that we apply to study results depends on the type of trial being reported. For example randomized controlled trials RCTs represent a higher level of evidence than observational trials. Thus RCTs more appropriately guide the practice of medicine. Observational trials are statistically and financially efficient however and almost invariably precede results from an RCT. Can we base the care of critically ill patients on the results of observational data The SOAP study The Sepsis Occurrence in Acutely Ill Patients SOAP study represents an observational trial conducted in intensive care units ICUs from 24 European countries during a two-week period.
