====================================================================


The authors of this ABC article, Frank Sullivan and Jeremy C Wyatt (*BMJ* 2005;331:1190-2, 19 Nov), inadvertently omitted an acknowledgment from the two tables at the top of p 1191 containing information on the analysis of approaches to changing clinical practice: internal and external processes. They were first published by Grol R. *BMJ* 1997;315:418-21.
