Migraine is a common and frequently disabling condition. Nevertheless, many migraine sufferers do not consult for migraine, are not medically followed up and self-treat the attacks. “Tour de France of migraine” consisted of free-access conferences held in six large towns in France following a wide public information campaign. This sensitization campaign aimed at providing participants with educational information on migraine disease and on current therapies. Headache sufferers were then invited to respond to two consecutive questionnaires delivered at the end of the conferences and 3 months later to assess the influence of the information delivered on their migraine management. Tour de France of migraine recruited mainly severe migraine sufferers, most of whom had already consulted and were medically followed up. However, migraine management was often suboptimal in these subjects since most of them found their acute treatment of attacks ineffective and only few of them received a prophylactic treatment. Three months after the conferences, more than half of respondents had consulted for headaches. There was a significant improvement in migraine-related disability, as reflected by a significant decrease in mean Headache Impact Test 6-item score, which might have been related to the higher proportion of subjects receiving a prophylactic treatment of migraine. The Tour de France of migraine campaign revealed the difficulty in sensitizing migraine sufferers towards the necessity of being medically followed up. Mainly patients with severe migraine attended the conferences and derived clinical benefit from the educational program. Other strategies should be developed to reach a wider population of migraine sufferers.
Migraine is a frequent condition affecting about 11% of adult populations worldwide , yet many patients remain undiagnosed or untreated. A nationwide population-based epidemiologic survey carried out in France indicated that 60% of subjects diagnosed as having migraine are not aware that they suffer from this disease . Moreover, although migraine is associated with high levels of disability and impairment of health-related quality of life, many migraine sufferers (50–80%) are not medically followed up and self-treat their attacks [2–4]. The disability associated with migraine is an important target for treatment, and effective acute and preventative treatments exist, but some of them are available by prescription only. Importantly, the absence of medical control may promote overuse of acute treatments, which may lead to medication-overuse headache, a condition often refractory to treatment .
Recently, the World Health Organization (WHO) in collaboration with three international associations (World Headache Alliance, International Headache Society, European Headache Federation) initiated “Lifting the burden”, a global campaign to reduce the burden of headache worldwide . The campaign central tenet is that the healthcare solution for headache in most areas of the world is education. Educational programs directed towards the general public and patients consulting general practitioners, aiming to raise awareness of headache disorders and their consequences are considered essential for the diagnosis and management of migraine and other headache disorders. Studies carried out in the setting of a health maintenance organization or specialized headache clinic indeed showed that addition of therapeutic patient education to routine medical management improves the outcome of migraine or tension-type headaches [7, 8]. Reinforcement of information of the general population may also improve migraine diagnosis and management for those subjects who are not aware of their disease or not medically followed up.
In this context, a series of conferences on migraine was organized in several towns of France (“Tour de France of migraine”) by the French Society for the Study of Migraine and Headache (SFEMC) to sensitize the general public towards migraine. These conferences targeted migraine sufferers as well as their close relations and aimed at providing information about migraine disease and the possibilities of current proper management of migraine. Headache sufferers were invited to respond to two consecutive questionnaires: the first one to establish their headache characteristics as they attended the conference, the second one 3 months later to assess the influence of the conference on the management of their headaches. Results from this study are presented below.
Patients and methods
The sensitization campaign on migraine was initiated by the SFEMC in association with the French Association of Private Neurologists (ANLLF). It was conducted from September to October 2007 in six towns of France: Lyon, Rouen, Lille, Marseille, Toulouse and Paris (“Tour de France of migraine”). The conferences intended for the general public took place on a Saturday morning and were free of registration fees. Each conference consisted of four seminars delivered by migraine specialists and dealing with definition, epidemiology, treatment and management of migraine, with a particular focus on the relationship between migraine and female hormones. The seminars were given with the help of visual aids which were elaborated by the SFEMC and the same for all towns. Seminars were then followed by debates. Information for attending the conferences was circulated via local media, via the SFEMC website and by means of public notices within 2 weeks beforehand.
The initial self-administered paper questionnaire was handed out at the end of the conference. It was especially intended for the individuals who said that they suffered from headaches. Three months later, all respondents to the first questionnaire who had provided their particulars and given their consent were contacted by phone by the polling institute TNS Healthcare and asked to respond to a second simplified questionnaire.
The initial 24-item study questionnaire queried about—(1) the reason why the subject attended the conference: because he/she or someone amongst his/her close relations was suffering from headaches, or only because he/she was interested in health information; (2) subjects’ demographics: age, sex; (3) attributes of headaches: persistent or recurrent quality, number of days per month, existence of aura symptoms before the attacks; (4) migraine diagnostic criteria for migraine without aura according to the International Classification of Headache Disorders, 2nd edition (ICHD-II), category 1.1 ; (5) headache-related disability as evaluated by the Headache Impact Test 6-item (HIT-6) assessing the impact of headaches on daily living activities ; (6) whether the subject had already consulted specifically for headaches, and if yes, which practitioner; and whether the subject was medically followed up for headaches; (7) the consumption of acute treatments of attacks, the name and dosage of the medication most frequently used as first-line treatment regardless of it was a non-prescription- or a prescription-only medication; (8) whether the subject took a preventive medication for migraine; and (9) whether the subject intended to consult for headaches after having attended the conference.
The medications used for the acute treatment of migraine were classified as recommended (triptans, ergotamine derivatives, non-steroidal anti-inflammatory drugs, aspirin alone or combined with metoclopramide) or non-recommended treatments (paracetamol, opioids) according to the French National Authority for Health (HAS) recommendations, while specific treatment included triptans, ergotamine derivatives and aspirin combined with metoclopramide . Effectiveness of the usual treatment of attacks was assessed according to the set of four questions designed by the SFEMC and the HAS. This questionnaire captures information about: (1) significant migraine relief 2 h after drug intake, (2) treatment tolerability, (3) single drug intake to treat an attack and (4) rapid resumption of normal social, family or professional activities. “Yes” responses to all four questions characterized treatment effectiveness [11, 12].
The second 16-item study questionnaire, administered by telephone, mainly consisted of the sections 5 and 7 of the initial questionnaire. In addition, the second questionnaire queried about whether the subject had consulted for headaches since the conference, and if yes, which practitioner was consulted.
Nominative data were recorded and subjects’ written informed consent was required to participate in the second phase of the survey. Therefore, study protocol was submitted to and approved by the French Commission on Data Processing and Liberties (CNIL). Participants received no compensation.
Data processing and statistical analysis
Responses to both questionnaires were processed by the polling institute TNS Healthcare Sofres. Categorical variables were summarized by the percentages in the corresponding categories. Numerical variables were summarized by the usual descriptive statistics (mean, SD). Statistical comparisons of data between subsets of subjects (e.g. subjects with or without medical follow-up, initial vs. second questionnaire) were performed using the Z test. Statistical significance was considered at P < 0.05.
A total of 143 questionnaires were collected during the sensitization campaign (Phase 1 of the survey) including one blank questionnaire. One hundred and twenty respondents gave their particulars to be contacted by phone 3 months after the conference (Phase 2 of the survey). Of them, 105 could be actually contacted and accepted to respond to the second questionnaire. The remaining 15 subjects gave false particulars or did not respond to phone call (n = 6), refused to participate to the second phase of the survey (n = 5) or stated that they were not migraine sufferers (n = 4).

Phase 2 of the survey: influence of the sensitization campaign on migraine management
Although migraine is a frequent disease associated with considerable disability, it remains largely unrecognized and improperly treated. The objective of Tour de France of migraine was to sensitize migraine sufferers and their close relations to the necessity of seeking the care of a physician to benefit from the current most effective therapies and avoid the risk of medication overuse. Despite a large information campaign, only a low proportion of headache sufferers attended the conferences and it appears that most of those who did generally had a more severe disease were already medically followed up. Furthermore, the influence of the information delivered on migraine sufferers’ behaviour and migraine management 3 months after the conferences seems to have been rather limited.
Migraine (strict or probable) affects more than one in five subjects in France (21%) . The conferences organized in six important towns in France only recruited 142 headache sufferers that accepted to participate in the survey, of whom 110 were recognized as true migraine sufferers. This low rate of participation conforms well to the notion that migraine sufferers show defeatism and resignation towards medical care of their disease and their willingness to manage their headaches by themselves : a preceding survey indicated that 28% of migraine sufferers in France never consulted for migraine and 41% lapsed consulting . Insufficient patient information, as reflected by the high proportion of migraine sufferers not self-aware that they have migraine , may be the cause of their unwillingness to seek medical care. Other factors may include the fact that migraine attacks are relatively short and rarely observed by the physicians, to whom they are described retrospectively and succinctly or even not reported at all, while the patients continue their own way to manage the attacks with the notion that only themselves have a good knowledge of their attacks. They would eventually consult a physician only to get a prescription, which would entail the risk of altering the normal patient–physician relationship .
The population who actually attended such conferences was mainly composed of headache sufferers (80% of subjects), most of them (96% of headache sufferers) being true migraine sufferers as defined by the ICHD-II diagnostic criteria for migraine. Moreover, the population of migraine sufferers recruited via this campaign consisted mainly of severe migraine sufferers, as attested by the HIT-6 score: most migraine sufferers had a HIT-6 score > 55 (range 49–76). The severity of the disease may explain the moderate impact of this campaign.
Similar observations were made in a sensitization campaign (Casilino study) on unrecognized migraine that was conducted in Italy in 2003 . Headache sufferers were recruited by a mailing to more than 8,000 households listed in the registries of a group of ten general practitioners and posters in the physicians’ waiting rooms. Migraine sufferers were first identified by the ID Migraine screening test , then migraine was diagnosed according to the ICHD-II criteria during a consultation. The authors expected to recruit 1,300–1,500 migraine sufferers via the personal mails addressed: in reality, only 195 headache sufferers consulted as a result of the sensitization campaign. Most participants (92%) were migraine sufferers and 73% were diagnosed for the first time. As in Tour de France of migraine, the migraine sufferers who actually consulted were those with severe headaches: mean HIT-6 score was 61.5 ± 7.6 and subjects suffered a mean number of 8.4 ± 9.0 days of headache per month with a mean pain intensity of 8.6 ± 1.5 on a scale of 0–10. Like ours, this sensitization campaign failed to bring a wide range of undiagnosed headache sufferers into medical care: patients with high-grade disability suffer migraine attacks of severe intensity and use multiple drug units to treat the attacks . As underlined by the authors of the Casilino study, more widespread use of rapid identification of potential migraine sufferers by the ID Migraine test might be very useful for a large recruitment of migraine patients to medical care. Interestingly, 92% of patients identified using ID Migraine in the Casilino study were true migraine sufferers, versus 96% of headache sufferers attending the conferences in the Tour de France of migraine, indicating that a wide public information campaign mostly reaches migraine sufferers and less subjects with other categories of common headache disorders such as tension-type headaches.
As expected, migraine sufferers not medically followed up used fewer specific and recommended treatments of migraine, more frequently took large number of medication units for an attack, and fewer received a preventive treatment of migraine. The conferences did not seem to have influenced the therapeutic behaviour of the migraine sufferers. This is in keeping with data from a pharmaceutical campaign conducted in Denmark targeting the inappropriate use of triptans which showed that intensive information of pharmacy staff had no significant impact after 6 or 9 months on the patients’ consumption of triptans .
Nonetheless, 3 months after the conferences, more migraine sufferers than initially received a preventive treatment of migraine (34 vs. 25%), as a possible result of the 27% of initially migraine sufferers without medical follow-up who consulted after the conferences or of specific request from consulting migraine sufferers after the sensitization campaign. Concomitantly, mean migraine impact on daily life as assessed by the HIT-6 score decreased slightly but significantly (−3.5; P < 0.05) during the period in the whole group of migraine sufferers. There was no significant difference in impact change following the sensitization campaign whether migraine sufferers had consulted or not, however, which makes difficult the identification of the cause of migraine impact alleviation.
The Tour de France of migraine sensitization campaign has some limitations, however. It concerned mainly the urban population of France, as it was conducted in only six large towns in France. However, the prevalence of migraine does not appear to differ according to community size . The proportion of responding subjects was quite low and probably not totally representative of the whole population of migraine sufferers since most participants were severe migraine sufferers and already enrolled in the healthcare system. On the other hand, a strength of the survey is the relatively high proportion of migraine sufferers (85%) that could be contacted again 3 months after the sensitization campaign, with no apparent bias due to population attrition. To extend this type of migraine sensitization campaign, it may be interesting to develop other ways of communication as the Internet, information close to the pharmacists, etc.
In conclusion, the Tour de France of migraine campaign that intended to sensitize headache sufferers to consult mainly reached severe migraine sufferers who were already medically followed up. Nevertheless, the sensitization campaign had some positive influence on migraine management, in that some migraine sufferers previously without medical follow-up actually consulted during the 3 months following the sensitization programme, more of them received a preventive treatment, and a slight but significant decrease in migraine impact on daily living was observed. No relationship between these changes could be firmly established, however. Other strategies should thus be developed to reach a more general population of migraine sufferers. Public information and individual patient’s therapeutic education are indeed becoming an essential part of the treatment of chronic diseases. It is now largely recommended that the combination of both, complementary but not equivalent, should integrate the therapeutic strategy of chronic diseases, such as asthma, diabetes and migraine [6, 19, 20]. This strategy would be particularly important for migraine, a condition where patient defeatism and unawareness of the current effective treatments of migraine might be at least in part responsible for the high rate of exclusion from medical care.
