Headache Characteristics in the Neurological Emergency Department: A Retrospective Study.

The care of patients with headache in the emergency department (ED) represents a diagnostic and clinical challenge. Data on the prevalence and characteristics of headache patients in purely neurological EDs are sparse. The aim of the present study is to examine patient profiles with the cardinal symptom of headache in an academic neurological ED, to analyze correlations between headache characteristics and search for differences compared to the interdisciplinary ED. This retrospective cross-sectional study assessed all patients who presented to the ED of the Department of Neurology at Rostock University Medical Center between November 2013 and November 2016 with the main symptom of headache. Epidemiological, clinical, diagnostic data as well as key data regarding the care structure were recorded. Correlations between headache characteristics and diagnosis at discharge were analyzed and risk profiles were identified using binary logistic regression analysis. This study comprehensively characterized a large collective of patients with the cardinal symptom of headache presenting to a purely neurology emergency department.
