Headaches are common and often do not require hospitalisation. However, headaches account for 1–4% of all emergency department visits and here, headaches are one of the most challenging complaints to assess. Potentially life-threatening causes are rare and imaging using CT or MRI is usually not indicated. However, neuro-imaging remains the most common investigation. Pathways to stratify neuro-imaging and admission would be helpful.

This dataset is a highly granular dataset of >33,000 patients who have presented to hospital with headache to University Hospitals Birmingham. The data includes demographics, vital signs (blood pressure, respiratory rate, heart rate, temperature, NEWS2 score, BMI and others), comorbidities, assessments, laboratpry sample results), medical events, medications given including dose and route, imaging (films and reports), onward referrals, treatments including surgery, mortality and readmissions both in the short and longer term. The data ranges from 2013 to 2023.
