Outpatient U.S. Medical Care Exceeds 1 Billion Visits

New reports from the Centers for Disease Control and Prevention examine ambulatory health care in America. They report on the more than 1 billion visits a year Americans make to doctors' offices, emergency rooms and hospital outpatient departments. The latest in an annual series, these reports provide a comprehensive analysis of visits to ambulatory health care settings in 2004.

  • Ambulatory care visits have increased at three times the rate of population growth over the past decade.
  • Infants under the 1 year of age had the highest rate of visits to primary care offices and hospital outpatient and emergency departments, compared to other age groups.
  • Hospital settings as opposed to physician offices were used morefrequently for ambulatory care by Medicaid recipients and by patients with self-pay, no charge, or charity indicated as the expected source of payment.
  • The amount of time a patient waits before seeing a physician in the emergency department increased from 38 minutes in 1997 to 47 minutes in 2004. There was no change in the average time--about 16 minutes--a patient spends face-to-face with a doctor in an office visit.
  • For the first time, seasonal estimates are available and show that overall, office visits decreased from spring through the summer.

Visits for mental disorders increased during the fall. Emergency injury visits were more likely to occur in the spring than other seasons.

Newly released data from the Centers for Disease Control and Prevention are presented in a Health E-Stat (web-based summary) and three reports:
