title: Visits to office-based physicians in the United States for medication-related morbidity.
abstract: OBJECTIVE
  To examine the prevalence, nature, demographics, and resource use associated with visits to office-based physicians in the United States during 1995 for medication-related morbidity.
  
  
  METHODS
  A nationwide cross-sectional survey of ambulatory care visits to physician offices, based on data from the National Center for Health Statistics' 1995 National Ambulatory Medical Care Survey.
  
  
  METHODS
  Physician office-based settings in the United States.
  
  
  METHODS
  Patients visiting office-based physicians for principal diagnoses of adverse effect of medications (ICD-9-CM E-code 930.00-947.9).
  
  
  METHODS
  Weighted measures of prevalence, nature, demographics, and resource use associated with visits related to adverse effects of medications.
  
  
  RESULTS
  An estimated 2.01 million (95% confidence interval, 1.69 to 2.34 million) visits for medication-related morbidity were made to office-based physicians in the United States during 1995, representing an annual rate of 7.70 visits per 1,000 persons. Medication-related visit rates were greater in women, in patients between 65 and 74 years of age, and in the Midwest. The most frequently cited reasons for medication-related visits were skin rash, nausea, and shortness of breath. The therapeutic agents responsible for medication-related visits were most often hormone and synthetic substitutes (13.32%), antibiotics (11.55%), and cardiovascular drugs (9.30%). Medication-related visits most often involved diagnostic services and medication therapy. The majority included instructions for a scheduled follow-up, and fewer than 1% resulted in hospital admission.
  
  
  CONCLUSIONS
  Medication-related ambulatory care utilization can pose a significant burden on health care resources unless specific strategies are initiated to control medication-related problems. The provision of pharmaceutical care can play an important role in reducing medication-related problems and associated health care costs.
