Objective: Characterize headache diagnosis and treatment in the primary care clinics of an academic medical center.
Background: Migraine affects 12% of the US population. It is thus a quintessential primary care problem. We asked how headache is diagnosed and treated in the primary care setting.
Methods: The University of Utah Electronic Data Warehouse was queried for primary care patient encounters (2008-2010) that contained one of 27 headache-related codes.
Results: 16,955 patients were identified, in 50,279 headache encounters at 13 clinics. 55.2% of encounters received a headache symptom code (784.0) rather than a diagnostic code. 41.6% received migraine diagnostic codes (346.xx), 3.2% received another headache diagnosis. 30.1% of all headache encounters were associated with an opiate prescription (range 15.1-62% by clinic). 36.3% of encounters with migraine diagnostic codes received opiates (12.1-75.9%); 19.1% received triptans (10.8-43.9%). Both triptans (OR 5.79, 95%CI 5.37,6.25) and opiates (OR 1.61, 95%CI 1.54,1.68) were more likely to be prescribed at migraine encounters than at headache symptom code encounters. The 9.1% of patients classified as heavy users (≥7 encounters) generated 45.5% of total headache patient encounters. Heavy users were more likely to be prescribed an opiate (OR 5.19, CI 4.97,5.42), less likely to be prescribed a triptan (OR 0.77, CI 0.71,0.81), and more likely to receive a migraine diagnosis (OR 2.46 CI 2.36,2.55) than light users (≤6 encounters). Heavy opiate prescribers (≥40 opiate prescriptions) represented 10.5% of the provider population but 65.4% of opiate prescriptions.
Conclusions: The frequent use of a symptom code for headache may reflect a discomfort with diagnosing migraine and other primary headaches in primary care. The rate of opiate prescription for headaches is high; conversely the rate of triptan prescription is low, even in migraineurs. These diagnosis and prescribing patterns may be related, and are the subject of an ongoing EMR-based intervention in our primary care clinics.
