To the Editor: The study by Dr Tricoci and colleagues1 and the accompanying Editorial by Drs Shaneyfelt and Centor2 both rightly justified a cautious approach to standardizing a field on a national level through the use of clinical practice guidelines. However, there is a difference between standardizing care in a field and standardizing care locally, in a hospital or within a specific unit.
