The authors investigated the sociodemographic differences in receiving a headache diagnosis for pediatric health care visits using 2 nationally representative databases--the National Ambulatory Medical Care Survey and the National Hospital Ambulatory Medical Care Survey. For those visits involving a headache diagnosis, the authors explored 2 possible disparities in care--being diagnosed by a neurologist and being prescribed an evidence-based medication. A headache diagnosis was less common during visits for private insurance patients versus Medicaid patients. In addition, while a headache diagnosis was equally likely for visits by Caucasian American children versus African American children and children of other races, visits for the latter 2 groups were less likely to involve a headache diagnosis from a neurologist. Finally, only 37% of the headache visits involved a prescription of an evidence-based medication. The authors conclude that some sociodemographic disparities exist in pediatric headache care across the United States.
