A POEM a week for the BMJ

In the opening paragraph of this editorial by Richard Smith (2 November, p 983) we said that the POEM (Patient-Oriented Evidence that Matters) concept was developed by David Slawson and Allen Shaughnessy. It was, but they developed it while they were at the Harrisburg Family Practice Residency in Pennsylvania, not at the University of Virginia, as suggested by our editorial. Allen Shaughnessy is still at Harrisburg, where he is the director of research and associate residency director; David Slawson is now at the University of Virginia. We should also, of course, have spelt Allen Shaughnessy's name correctly every time it came up; unfortunately we didn't—in the second paragraph we left the second “h” out.
