ID-Migraine™ questionnaire and accurate diagnosis of migraine

Abstract

Headache is a major worldwide health problem and the second most common type is migraine, with a global prevalence among adults greater than 10%. Migraine mainly affects adults between 25 and 55 years, during the most productive years of life 1 . In Brazil, the prevalence of migraine is estimated to be 15.2% 2 .Lipton et al. 3 demonstrated that migraine is still underdiagnosed and inappropriately treated. They evaluated 4,376 individuals with headache through a computer-assisted telephone interview survey and 536 individuals had migraine, as defined by the International Classification of Headache Disorders -2nd edition 4 (ICHD-2). They found that 48% of migraine sufferers had seen a doctor for headache within the last year and 73% of these reported a physician-made diagnosis of migraine. Of all migraine sufferers, 49% were treated with over-the-counter medications, 23% with prescription medication, 23% with both, and 5% with no medications at all 3 .A study by Bigal et al. 5 with 6,006 participants, conducted in the State of São Paulo, Brazil revealed that migraine was the most prevalent primary headache, accounting for 45.1% of patients reporting headache as their only symptom. In another Brazilian study, the correct diagnosis of migraine by non-specialists was made in only 44.9% of migraine sufferers, The diagnosis of headache was made according to the ICHD-2 criteria. Results: Of the 232 patients, 86% had migraine. The questionnaire showed a sensitivity of 92% (95%CI, 88% to 95%), specificity of 60% (95%CI, 43% to 77%) and a positive predictive value of 93% (95%CI, 89% to 96%). Discussion: Our results were similar to other international studies of the ID-Migraine TM application. The Portuguese version is considered easy to use, and an appropriate screening tool for migraine diagnosis in our sample. Conclusion: Considering the characteristics of our health system, we can infer that this questionnaire would be beneficial in a Brazilian primary care setting; however, more studies are necessary.Keywords: migraine disorders; surveys and questionnaires; headache. O questionário apresentou sensibilidade de 92% (IC de 95% 88% a 95%), especificidade de 60% (IC de 95% 43% a 77%) e valor positivo preditivo positivo de 93% (IC 95 89% a 96%). Discussão: Nossos resultados foram similares a outros estudos mundiais de aplicação do ID-Migraine TM . A versão em Português é considerada de fácil utilização, sendo uma ferramenta adequada para triagem diagnóstica de migrânea em nossa amostra. Conclusão: Considerando as características do nosso sistema de saúde, podemos inferir que este questionário seria útil nos serviços primários de saúde brasileiros, porém mais estudos são necessários.Palavras-chave: transtornos de enxaqueca; inquéritos e questionários; cefaleia.

Assessment of Work Productivity and Activity Impairment (WPAI) questionnaire for migraine with the help of a smartphone app

“…Socio-demographic data were expressed as mean±SD or percentages. The headache was considered as migraine in subjects who answered "Yes" to at least two out of the three questions of the Migraine ID-questionnaire 11,12,13,14 . Only data from subjects considered to have migraine were included in the present analysis.…”

“…The work activities were classified as employee ( full time or part-time) or self-employed. After this first step, the following questionnaires were applied with the app: ID migraine, in its validated Brazilian Portuguese version 11,12,13,14 , Brazilian Portuguese validated Headache Impact Test (HIT-6) 15,16 , and Brazilian Portuguese migraine/ headache WPAI 9 .…”

Factors associated with delayed diagnosis of migraine: A hospital-based cross-sectional study

“…Various studies tried to simplify the diagnosis criteria of migraine to save time without compromising sensitivity and specificity. [32333435] Most of these studies tried to select few sensitive and specific clinical features for diagnosis of migraine. Prolonged duration of severe headache (4-72 hours), which limits physical or intellectual activity, photophobia and phonophobia, and nausea and/or vomiting were reported by most of these studies as useful questions to diagnose migraine.…”

“…This observation re enforces the statement that diagnosis of migraine should be considered in a person with recurrent headache for at least more than 3 months; of moderate-to-severe intensity; duration (4-72 hours); restricting physical/intellectual activity associated with nausea/vomiting, and photophobia/phonophobia. [32333435] Inappropriate diagnosis has its financial burden on patients. In our study, patients with delayed diagnosis paid more money from their pocket than those with early diagnosis.…”

A Cross-sectional Study on the Burden and Impact of Migraine on Work Productivity and Quality of Life in Selected Workplaces in the Philippines

“…The test has been validated in multiple contexts and has been used in previous migraine population-level studies because of its simplicity and accuracy compared to a clinical diagnosis. (12)(13)(14) A systematic review found that the pooled sensitivity of the test is 84% (95% con dence interval (CI): 75% − 90%) and speci city is 76% (95% CI: 69% − 83%). (12)…”
