Migraine consultation patterns in primary care. Results from the PCAOM study 1994-96

Abstract

In order to establish a basis for the planning of improved medical care of migraine in Germany, we report on the proportion of migraine patients under primary care and the continuity of consultations for migraine as determined by age, gender, and history of migraine and nonmigraine practice contact (Primary Care of Migraine, PCAOM Study). A primary-care-physician- based migraineurs' sample of 16,573 women and 4,636 men (MediPlus, IMS Health) was placed in relation to cases expected according to International Headache Society criteria in the base population, and was followed for up to 3 years for repeat consultations. Overall, no more than 51% and 37%, respectively, of female and male statutory health-insured migraine headache sufferers had a migraine diagnosis mentioned at least once a year in primary care. At younger ages, substantially less advantage was taken of available primary healthcare for migraine; 79% of the women and 74% of the men were estimated to present again to the same primary-care physician within 3 years because of migraine, the corresponding figures for patients with no history of migraine in the practice concerned being 41% and 31%, respectively. Following first migraine contacts, time to recontact and quarterly recontact prevalences for migraine did not differ, whether on the basis of an established nonmigraine primary care relationship or a first encounter with a medical practice. Trust evidenced by an existing nonmigraine doctor-patient relationship apparently did not carry over to migraine. Results indicate that one of the greatest challenges in relation to the care of migraine patients in Germany is to establish and maintain solid doctor-patient relationships.
