Narrated and Abridged: There is (No) Evidence for That: Epistemic Problems in Critical Care Medicine

Below is the narrated video of my powerpoint presentation on Epistemic Problems in Critical Care Medicine, which provides a framework for understanding why we have both false positives and false negatives in clinical trials in critical care medicine and why we should be circumspect about our "evidence base" and our "knowledge".  This is not trivial stuff, and is worth the 35 minutes required to watch the narration of the slideshow.  It is a provocative presentation which gives compelling reasons to challenge our "evidence base" in critical care and medicine in general, in ways that are not widely recognized but perhaps should be, with several suggestions about assumptions that need to be challenged and revised to make our models of reality more reliable.  Please contact me if you would like me to give an iteration of this presentation at your institution.


  1. Glitch: There's a brief narration overlap beginning at 7:18.

  2. Yes, I apologize for that. There is not a good way to put narrated videos on the web right now. Slideshare doesn't allow the narration, you would have to do a podcast and post the ppt presentation separately. For some reason I can't upload to microsoft either. The best way I could find to preserve the changing of the slides and the pointer data with narration overlaid was to use a ppt function which converts to wmv video file which I can then upload to youtube. Unfortunately, it takes several hours to do the conversion and about a half hour to do the upload to youtube. Somewhere along that process, the files were corrupted, and I worry that redoing it will make it worse, so I'm electing to leave it as is. Hopefully it doesn't markedly disrupt the cogency of the presentation.
