Data Source: National Ambulatory Medical Care Survey (NAMCS)
All data were derived from the National Ambulatory Medical Care Survey (NAMCS). Data are gathered about physicians through in-person interviews, and about visits by abstracting information from the visit record. Assumptions were made that if Medicaid or Medicare were selected as an expected payment source then they would be the primary source of payment. If a visit had Medicaid or Medicare as payment type, then the individual's insurance was coded as either Medicaid or Medicare (even if other private insurance was listed). Only 4% of Medicaid recipients listed private insurance as another payment source; whereas approximately 45% of Medicare recipients listed private insurance as another payment source. If both Medicare and Medicaid were listed as payment type, then the individual was coded as dual eligible. Numerator: All visits to physicians in the specialties of general/family practice, internal medicine, pediatrics, and obstetrics/gynecology for which depression screening was ordered or provided at the visit. Denominator: All visits to office-based physicians in the specialties of general/family practice, internal medicine, pediatrics, and obstetrics/gynecology.
The green lines in the chart below indicate the value +/- the standard error. The lower and upper standard error values can be seen in the table view. For more information on standard errors, please see the Glossary under Help.
