About this study

Official title: Comparing Patient-Reported Outcomes Between Rimegepant and Triptan Users With Migraine in the United States

This is a cross-sectional study using the cross-sectional 2023 National Health and Wellness Survey (NHWS) data from the US, with a large and nationally representative population (N=75,007).

All data from the NHWS are reported by respondents, who are recruited through an existing, general-purpose, web-based, consumer panel via opt-in e-mails, co-registration with panel partners, e-newsletter campaigns, banner placements, and affiliate networks. All respondents explicitly agree to be a panel member, register with the panel through a unique e-mail address, and complete an in-depth demographic registration profile.

This analysis will focus on respondents who self-report having migraine diagnosed by a physician. Individuals who use rimegepant for acute treatment of migraine will be compared with those who use triptans for acute treatment of migraine. Outcomes of interest include treatment satisfaction, healthcare resource utilization (HCRU), quality of life (QoL), work productivity loss, and migraine-specific disability outcomes.

Inverse probability of treatment weighting (IPTW) will be used to adjust for differences that may exist between rimegepant and triptan users prior to comparing outcomes.

The scores for percentage overall work impairment experienced ranged from 0 (no impairment/high productivity) to 100% (high impairment/total loss of work productivity) with higher score indicating greater impairment and less productivity. Analysis was performed using IPTW method to adjust for confounding by the covariates.

    Measured: 7 days before the survey was taken, during 1 year of data identification (Year 2023); available retrospective data was evaluated over approximately 1.41 months of this observational study

  7. Percentage Total Activity Impairment in Past 7 Days Based on WPAI-GH Questionnaire- Sensitivity Analysis

    The WPAI is a standardized PRO that assessed the previous 7 days of completing the questionnaire. WPAI:GH is a self-reported measure of work productivity and impairment, which had four scores: absenteeism (work time missed); presenteeism (impairment at work/reduced on the job effectiveness); work productivity loss (overall work impairment/absenteeism plus presenteeism); and total activity impairment. The scores for percentage of total activity impairment ranged from 0 (no impairment/high productivity) to100% (high impairment/total loss of work productivity) with higher score indicating greater impairment and less productivity. In this outcome measure, percentage total activity impairment among total population, employed, unemployed and disabled is reported. Analysis was performed using IPTW method to adjust for confounding by the covariates.

    Measured: 7 days before the survey was taken, during 1 year of data identification (Year 2023); available retrospective data was evaluated over approximately 1.41 months of this observational study.

  8. Migraine Disability Assessment Scale (MIDAS) Total Score and Individual Item Scores- Sensitivity Analysis

    MIDAS is a retrospective, self-administered, 7-item questionnaire that measured headache-related disability as lost time due to headache from paid work or school, household work, and non-work activities. Participants provided the number of missed work or school days (MIDAS Item 1); missed household chores days (MIDAS Item 2); missed social or leisure activity days (MIDAS Item 3); and days with productivity loss at work or school (MIDAS Item 4), days with productivity loss in household work (MIDAS Item 5), frequency of headaches (MIDAS Item 6) and the intensity of the headache pain (MIDAS Item 7). The score ranged from 0 (no disability) to 90 (maximum disability) for each of individual item scores. The 5 item scores (Item 1 to Item 5) were summed to compute the MIDAS total score ranging from 0 (no disability) to 450 (maximum disability). Lower scores indicate less headache-related disability. Analysis was performed using IPTW method to adjust for confounding by the covariates.

    Measured: 3 months before the survey was taken, during 1 year of data identification (Year 2023); available retrospective data was evaluated over approximately 1.41 months of this observational study

  9. Number of Participants According to MIDAS Grade - Sensitivity Analysis

    MIDAS is a retrospective, self-administered, 7-item questionnaire that measured headache-related disability as days with lost time or productivity due to headache from paid work or school, household work, and non-work activities.

Analysis was performed using IPTW method to adjust for confounding by the covariates.
