Utilization of health services in physician offices and outpatient clinics by adolescents and young women in the United States: implications for improving access to reproductive health services.

PURPOSE: We examined utilization patterns of adolescents and young women as they seek general and reproductive health services in physician offices and hospital outpatient clinics.
METHODS: We analyzed physician office visits in the 2003-2006 National Ambulatory Medical Care Surveys, and hospital outpatient clinic visits in the National Hospital Ambulatory Medical Care Surveys, to examine utilization patterns of females aged 9-26 years by 2-year age intervals and other characteristics such as physician specialty or clinic type.
RESULTS: The number of visits to primary care physician offices increased with age, from 4.9 million for ages 9-10 years to 9.0 million for ages 25-26 years. The proportion of visits made to obstetrician-gynecologists and family practitioners increased with age, and by ages 15-16 years fewer than half of all visits to primary care providers were made to pediatricians. The proportion of visits to family practitioners increased from 25% at ages 9-10 years to 30% at ages 25-26 years. By ages 17-18 years, a larger proportion of visits were made to obstetrician-gynecologists (33% of 7.0 million visits) and to family practitioners (34%) than to pediatricians (23%). The proportion of visits for reproductive health services peaked at 53% of 7.5 million physician visits at ages 20-21 years. Similar utilization patterns were observed for the 11.0 million hospital outpatient visits to primary care providers.
CONCLUSIONS: Because adolescents and young women most commonly utilize healthcare services provided by obstetrician-gynecologists and family practitioners, these specialties should be priority targets for interventions to improve the quality and availability of reproductive health services.
