My friend Ivan Oransky runs a highly successful blog called Retraction Watch; if you have not yet discovered it, you should! In it he and his colleague Adam Marcus document (with shocking regularity) retractions of scientific papers. While most of the studies are from the bench setting, some are in the clinical arena. One of the questions they have raised is what should happen with citations of these retracted studies by other researchers? How do we deal with this proliferation of oftentimes fraudulent and occasionally simply mistaken data?
A more subtle but no less difficult conundrum arises when papers cited are recognized to be of poor quality, yet they are used to develop defense for one’s theses. The latest case in point comes from the paper I discussed at length yesterday, describing the success of the Keystone VAP prevention initiative. And even though I am very critical of the data, I do not mean to single out these particular researchers. In fact, because I am intimately familiar with the literature in this area, I can judge what is being cited. I have seen similar transgressions from other authors, and I am sure that they are ubiquitous. But let me be specific.
In the Methods section on page 306, the investigators lay out the rationale for their approach (bundles) by stating that the “ventilator care bundle has been an effective strategy to reduce VAP…” As supporting evidence they cite references #16-19. Well, it just so happens that these are the references that yours truly had included in her systematic review of the VAP bundle studies, and the conclusions of that review are largely summarized here. I hope that you will forgive me for citing myself again:Continue reading…
