David Eddy did nothing to reassure Kent Bottles about evidence-based guidelines in his recent keynote, saying essentially: “The problem is that we don’t know what we are doing” (!!)

Dr. Eddy did say that quotation in the BusinessWeek article referenced in the original blog post. In the Reinertsen Lecture he did a masterful job of showing how today’s evidence-based guidelines are better than no guidelines at all. However, he did point out that today’s evidence-based guidelines do have limitations. For example, many patients have multiple diseases, the need for sharp cut-offs in guidelines do result in the need for clinical judgment, and the need for shared decision-making between patient and provider. Dr. Eddy did reassure me that computer-based simulation may be a way to move evidence-based medicine forward from today’s single disease guidelines. I would refer readers to the comment by Al Burgener in the original ICSI blog: we need Informed Judgment
