title: Illuminating the 'black box'. A description of 4454 patient visits to 138 family physicians.
abstract: BACKGROUND
  The content and context of family practice outpatient visits have never been fully described, leaving many aspects of family practice in a "black box," unseen by policymakers and understood only in isolation. This article describes community family practices, physicians, patients, and outpatient visits.
  
  
  METHODS
  Practicing family physicians in northeast Ohio were invited to participate in a multimethod study of the content of primary care practice. Research nurses directly observed consecutive patient visits, and collected additional data using medical record reviews, patient and physician questionnaires, billing data, practice environment checklists, and ethnographic fieldnotes.
  
  
  RESULTS
  Visits by 4454 patients seeing 138 physicians in 84 practices were observed. Outpatient visits to family physicians encompassed a wide variety of patients, problems, and levels of complexity. The average patient paid 4.3 visits to the practice within the past year. The mean visit duration was 10 minutes. Fifty-eight percent of visits were for acute illness, 24% for chronic illness, and 12% for well care. The most common uses of time were history-taking, planning treatment, physical examination, health education, feedback, family information, chatting, structuring the interaction, and patient questions.
  
  
  CONCLUSIONS
  Family practice and patient visits are complex, with competing demands and opportunities to address a wide range of problems of individuals and families over time and at various stages of health and illness. Multimethod research in practice settings can identify ways to enhance the competing opportunities of family practice to improve the health of their patients.
