This study aims to describe the epidemiological profile of migraine cases treated in three public emergency departments in Chile. Methods A descriptive epidemiological study was conducted using data from patients diagnosed with migraine in three emergency departments. Patient demographics, clinical presentation, and treatment approaches were analyzed. Results During the study period, 199,263 patients were seen across three hospitals. Migraine consultations accounted for 1.47% of visits, with 1.65% at HLF, 1.2% at HFB, and 1.58% at HCM. The majority of cases were in women at HLF and HFB, while men represented 71.6% of cases at HCM. The highest frequency of cases was observed in the active age groups. Conclusions This study highlights the burden of migraine in public emergency departments in Chile. The findings emphasize the need for optimized treatment protocols and preventive strategies to improve patient outcomes.
