A Pragmatic Observational Study to Investigate Machine Prescription as Compared to Treatment-as-usual in Adults Aged 18 Years or Older With Migraine
The purpose of this study is to estimate the ability of ML models to predict the effect of migraine preventives. This will be achieved by first identifying sociodemographic, headache and comorbidity features of migraine patients. Headache days will then be measured for 4 weeks before starting a migraine preventive, and this will be compared to the number of headache days in the first 12 weeks (divided into 28-day periods) after starting treatment. The preventive is regarded as effective if there is a 50% or greater reduction in monthly headache days. After observation of the treatment period, the ML models will use the sociodemographic, headache and comorbidity features, captured before treatment was initiated, to predict treatment effect for all preventives in each participant. These predicted treatment effects will be compared to the actual treatment effects that were observed.
• Aged 18 years or older at trial entry. Episodic or chronic migraine with or without aura as per ICHD-3 criteria. Onset of migraine before age 50 years. History of at least 4 days of migraine in the 4-week baseline period based on retrospective or prospective headache diary assessment or subject recall.
• Having recently (within last 4 weeks) started or planning to start a migraine preventive.
• Signed and dated informed consent.
