  1. *Unique patients seen one or more times by General Medicine or PrimeCare practitioners between July 1, 2002 (start of pre-intervention period) and September 30, 2004 (end of intervention period). Numbers will not match those in Table 4 because we studied a dynamic cohort during the 33-month observation period, with patients entering as they met inclusion criteria and exiting due to death or departure from the VA health care system.
