The added value of an electronic monitoring and alerting system in the management of medication-overuse headache: A controlled multicentre study

BackgroundMedication-overuse headache (MOH) is a chronic disabling condition associated with a high rate of relapse.MethodsWe evaluated whether the adoption of electronic-assisted monitoring, advice and communication would improve the outcome over a follow-up of 6 months in a controlled, multicentre, multinational study conducted in six headache centres located in Europe and Latin America. A total of 663 MOH subjects were enrolled and divided into two groups: the Comoestas group was monitored with an electronic diary associated with an alert system and a facilitated communication option, and the Classic group with a paper headache diary.ResultsWe observed a significantly higher percentage of overuse-free subjects in the Comoestas group compared with the Classic group: 73.1 vs 64.1% (odds ratio 1.45, 95% confidence interval 1.07–2.09, p = 0.046). The Comoestas group performed better also regarding the number of days/month with intake of acute drugs and the level of disability [Migraine Disability Assessmen...
