Validation and comparison of the coding algorithms to identify people with migraine using Japanese claims data.

ABSTRACT:

Purpose

The study aimed to validate and compare coding algorithms for identifying people with migraine within the Japanese claims database.

Methods

This study used the administrative claim database provided by DeSC Healthcare, Inc., that was linked to the results of an online survey administered to adult users of the health app "kencom^®." The ability of the 12 algorithms to detect migraines using diagnostic records alone or with prescription records was evaluated based on sensitivity, specificity, positive predictive values (PPVs), and negative predictive values (NPVs). We used a migraine diagnosis judged based on respondents' self-reported symptoms according to the diagnostic criteria of the International Classification of Headache Disorders, version 3 (ICHD-3),
