title: Major health-care providers and the 10 leading reasons for adolescent ambulatory visits.
abstract: BACKGROUND
  Epidemiological research underpins the importance of effective health-care strategies for adolescents. This descriptive study compares the 10 most common diseases among Taiwanese adolescents for 2000 and 2009.
  
  
  METHODS
  Data for a total of 69,594 visits in 2000 and 65,802 visits in 2009 by adolescents aged between 10 and 20 years were collected from the National Health Insurance Research Database. A maximum of three outpatient diagnostic codes (International Classification of Disease, ninth revision) could be listed for every visit. The data categories were: principal diagnosis, patient age, and physician specialty.
  
  
  RESULTS
  The middle adolescent age group utilized the least amount of medical services. Respiratory (46.2% in 2000, 40.5% in 2009) and digestive (16.5% in 2000 and 16.9% in 2009) tracts were the leading two diagnostic categories for adolescent ambulatory visits. Teeth (6.8%, 6.1%) and eye (4.0%, 3.1%) problems were also among the top 10 diseases. Family practitioners, ear-nose-throat specialists, and traditional Chinese medicine physicians were the major health-care providers for Taiwanese adolescents, especially in the middle and late groups. Although noted as the first option for consultation in the early group, the role of pediatricians with regard to adolescent health care declined in importance with age.
  
  
  CONCLUSIONS
  Nearly 99% of the population in Taiwan is covered under the national health insurance system. The different disease patterns and major health-care providers between Taiwan and other countries are compared.
