To the Editor: I support Tattersall and colleagues1 in their attempt to use a wee bit of science and a dose of common sense to improve doctors' letters. While I would love to receive letters based on their proposed "prompt sheet", and should really try much harder myself to follow it, I'd be only too pleased — in the interim, while we await enlightenment — to receive any letter from some of my colleagues with whom I share what is supposed to be "multidisciplinary care" of patients. There is a research project in this for the brave to find out why, too often, communication is not merely inadequate but non-existent.
