Application of ID Migraine as a self-administered screening instrument for Migraine in the orofacial pain clinic: Korean experience

Abstract

Objectives. To evaluate the use of ID Migraine as a self-administered screening instrument for migraine in the orofacial pain clinic setting.Study design. The ID Migraine is a self-administered questionnaire containing 9 items related to the severity and nature of headache, the presence of associated migraine symptoms, and the extent to which the headaches resulted in disability. A total of 176 patients from the TMJ and Orofacial Pain Clinic, School of Dentistry, Yonsei University, presenting with orofacial pain complaints and reporting headaches in the past 3 months completed all 9 items of the ID Migraine screening. Migraine diagnosis was assigned based on the International Headache Society criteria (2nd edition) after completing a diagnostic interview.Results. All 9 diagnostic screening questions provided optimum performance, with a sensitivity of 81.08%, a specificity of 87.25%, and positive predictive value of 82.19%. The analysis revealed that unilateral, throbbing, moderate-to-severe pain, nausea, photophobia, and aura provide statistically significant odds ratios of 5.6, 3.9, 4.7, 7.0, 9.9, and 3.0, respectively. However, statistical analysis for the validated 3-item subset of ID Migraine (nausea, photophobia, and disability) did not increase predictability compared to the combination of all 9 items owing to the statistically insignificant odds ratio of the disability item.Conclusions. Our results illustrated slightly different outcomes and performance in using ID Migraine as a migraine screening for orofacial pain population compared to a primary care setting. These findings indicate that all 9 items of ID Migraine may be required for this Korean orofacial pain population to achieve the optimum performance. Further validation study is warranted.
