BACKGROUND: To describe the epidemiology and clinical characteristics of migraine and the status of treatment in Colombia. Additionally, the use of health resources by patients was measured.
METHODS: This was a non-interventional, retrospective, descriptive study conducted in one Colombian Health Management Organization (HMO) from 2018 to 2022 with a follow-up period of 5 years. Migraine patients were identified using the International Code Disease 10th version G43, and the diagnosis was confirmed by a neurologist. The first recorded migraine diagnosis was defined as the index date. Medical records, claim databases and other electronic databases from the HMO were used to determine the clinical characteristics, treatments, and health care services.
RESULTS: A total of 89,227 patients were included in the study. The mean follow-up period was 3.7 years (standard deviation 1.2). Most of them were women (84.9%). Many patients were first seen by a general practitioner (82.6%), and only 8.9% were first seen by a neurologist. The prevalence of migraine during follow-up was between 1.69 and 2.42 patients in 100 HMO affiliates in 2020, the year with the highest prevalence (2.42 [95% CI 2.41-2.44]), and the incidence ranged from 0.032 to 1.72 per 100 patient-year at risk of developing migraine. Hypertension (21.3%), arrythmia (4.1%) and structural heart disease (3.4%) were the most common cardiovascular diseases. The annual mean number of outpatient consultations in 2018 was 1.43 consultations per patient, which decreased to 0.68 in 2022. The most frequent treatments for acute events were nonsteroidal anti-inflammatory drugs (NSAIDs) (range 37-42%) in monotherapy, combinations of analgesics (range 14-35%), and corticosteroids (range 10-15%). Triptans were used in 4% of patients in the first medication record, reaching a maximum of 16% of patients. Among preventive treatments, beta-blockers (24-49%) and antiepileptics (29-41%) were the most common.
CONCLUSION: The prevalence of migraine in Colombia according to health electronic databases was lower than that reported in previous studies conducted in the country. The treatment patterns for acute and preventive treatment of migraine follow the recommendations of different guidelines. Cardiovascular disease is relevant for the management of migraine.
