Usefulness of ICHD3B criteria to differentiate primary from non-primary headaches at the emergency service

Abstract:

Objectives: To determine the usefulness of ICHD3B criteria to differentiate primary from non-primary headaches at the ER. Patients and methods: Cross-sectional study comparing the prevalence of ICHD3B fulfilled criteria, age over 50, sleep headache onset, associated symptoms, abnormal neuro-exam, sudden onset, immunosuppression, consumption of analgesics before consultation and history of migraine. PRs (Prevalence Ratios) were calculated. Results: Headache was responsible for 276 (2.5%) out of 11,450 admissions. Median age was 32 years, IQR (25%–75%): 23–50.5, range 18–88, 77.8% females. Primary, non-primary and unclassified headaches were 59%, 34% and 7% respectively. Migraine and cervicogenic headache associated to myofascial trigger points were the most frequent causes for primary and non-primary causes respectively.
