To estimate the proportion of Emergency Department (ED) headache patients without neurological features who are diagnosed with a serious secondary headache cause.
Unplanned secondary analysis of HEAD Study/HEAD Colombia data. Patients without a known history of cerebral conditions and with a normal neurological assessment were included. The outcome of interest was the proportion of patients diagnosed with a serious secondary headache cause.
One hundred ninety-one patients were diagnosed with a serious secondary headache cause (191/3951, 4.8%, 95% CI 4.2%-5.5%).
Absence of neurological features alone cannot be used to reliably exclude a serious secondary headache cause in ED patients.
估计急诊科（ED）中无神经功能特征的头痛患者被诊断为严重继发性头痛病因的比例。
对HEAD研究/哥伦比亚HEAD研究数据进行非计划的二次分析。纳入无已知脑部疾病史且神经学评估正常的患者。感兴趣的结果是被诊断为严重继发性头痛病因的患者比例。
191例患者被诊断为严重继发性头痛病因（191/3951，4.8%，95%可信区间4.2%-5.5%）。
仅无神经功能特征不能可靠地排除急诊科患者存在严重继发性头痛病因。
