title: Physician office visits of adults for anxiety disorders in the United States, 1985-1998.
abstract: OBJECTIVE
  To determine the number of physician office visits by adults in which an anxiety disorder diagnosis was recorded and rates of treatment during these visits.
  
  
  METHODS
  We used data from the 1985, 1993, 1994, 1997, and 1998 National Ambulatory Medical Care Surveys, which is a nationally representative series of surveys of office-based practice employing clustered sampling.
  
  
  METHODS
  Office-based physician practices in the United States.
  
  
  METHODS
  A systematically sampled group of office-based physicians.
  
  
  RESULTS
  The number of office visits with a recorded anxiety disorder diagnosis increased from 9.5 million in 1985 to 11.2 million per year in 1993-1994 and 12.3 million per year in 1997-1998, representing 1.9%, 1.6%, and 1.5% of all office visits in 1985, 1993-1994, and 1997-1998, respectively. The majority of recorded anxiety disorder diagnoses were not for specific disorders, with 70% of anxiety disorder visits to primary care physicians coded as "anxiety state, unspecified." Visits to primary care physicians accounted for 48% of all anxiety disorder visits in 1985 and 1997-1998. Treatment for anxiety was offered in over 95% of visits to psychiatrists but in only 60% of visits to primary care physicians. Primary care physicians were less likely to offer treatment for anxiety when specific anxiety disorders were diagnosed than when "anxiety state, unspecified" was diagnosed (54% vs 62% in 1997-1998). Prescriptions for medications to treat anxiety disorders increased between 1985 and 1997-1998 while use of psychotherapy decreased over the same time period in visits to both primary care physicians and psychiatrists.
  
  
  CONCLUSIONS
  Although there is a large number of office visits with a recorded anxiety disorder diagnosis, under-recognition and under-treatment appear to be a continuing problem, especially in the primary care sector. Medication is being substituted for psychotherapy in visits to both psychiatrists and primary care physicians over time.
