Selective decontamination: no oracle needed

چکیده
We read with interest the study by Cuthbertson and colleagues [1] in a recent issue of Critical Care, and we appreciate their attempts to support studies regarding selective decontamination of the digestive tract (SDD). However, we have some concerns. The argument supporting a randomized controlled trial (RCT) for the evaluation of SDD is ambiguous. The Delphi method embraces ‘quasi-anonymity’, in which the researcher is aware of the responses of the participants [2]. The selection of experts is prone to bias, as participants were chosen on the basis of their inclusion among a particular group. Moreover, participants’ perception of SDD via a self-rated questionnaire is often misleading. Capacity to accurately reflect upon self-knowledge may be skewed, as we inflate the scope of our experience and understanding. The validity of a consensus is dubious, as dissidents are encouraged to alter their responses so as

The microbial ecology in the human digestive tract is diverse and here environmental triggers, immune signals and genetic susceptibility can affect the human host’s response to infection [1]. Selective decontamination has emerged as a potential treatment for patients at high risk of infection such as those; in the critical care environments, undergoing invasive surgical operations, or with sign...
