[Development of a screening tool for migraine prophylaxis].

The aim of the present study was to develop a screening tool to aid non-headache specialists, like general practitioners, in deciding whether migraine prophylaxis in the individual migraine patient is useful or not. The first step was the development of a questionnaire, consisting of 10 items, which was filled in by 132 migraineurs who called on neurologists or headache experts. Independently, the physicians filled in another questionnaire to answer the question of whether they decided to prescribe migraine prophylaxis and if they had, to give their reasons for doing so. Using logistic regression analysis, we identified the three questions which had the most influence on the decision regarding prophylaxis in the data set. As results, we identified the following three questions: 1. Do you suffer from migraine on more than 3 days/month? 2. Do you have to rest in bed while experiencing a migraine attack? 3. Do you have to take medication against migraine on more than 5 days/month? Validation of this reduced questionnaire is currently ongoing and involves 150 migraine patients of general practitioners.
