Abstract
OBJECTIVE: To test the hypothesis that the effect of video consultations is noninferior to traditional consultations in managing patients with overuse headache (MOH). MATERIALS AND METHODS: Patients were recruited from referrals to a neurological clinic. In a randomized controlled trial (RCT), headache burden measured by headache impact test (HIT-6) and frequency of headache days <15 per month and visual analogue pain scale (VAS) at baseline, 3 months and 1 year were compared between groups consulted by video- (n = 51) and traditional consultations (n = 51) in a post hoc analysis. RESULTS: The overall response rate was 74.5%. HIT-6 changed from 66.3 (SD = 4.7) to 60.0 (SD = 9.1) from baseline to 12 months in participants randomized to video consultations and from 65.8 (SD = 3.7) to 58.4 (SD = 8.3) in the group consulted traditionally (95% CI -2.3 to 6.5, p = 0.44). Frequency of headache days <15 per month at 1-year follow-up were 9 (23.1%) respectively 10 (27.0%), p = 0.60. In the video group, VAS improved by 2.3 points compared to 2.4 in the traditional group from baseline to 12 months (95% CI -1.2 to 1.2, p = 0.76). Analyses of repeated measurements comparing HIT-6 and VAS over two points of time in the two groups were insignificant. CONCLUSION: The effect of video consultations is noninferior to traditional consultations in managing MOH patients. Using video may be a good alternative in consulting patients with MOH.
