To the Editor: Dr Hofer and colleagues1 carefully analyzed data from the diabetes Patient
Outcome Research Team (PORT) to assess the validity and reliability of individual
physician practice profiles. Both the study authors and Dr Bindman,2 in his editorial, argue that individual physician
variation explains a small proportion of variation in profile measures and
suggest that efforts to expand profiling should proceed with caution.
