Design outcomes

Primary

MeasureTime frame
-The number of access/distribution of the QR code in the leaflet. The basis for setting: Although the hard endpoint is the vaccination rate, estimating the number of vaccinations takes time. Therefore, the number of accesses/distribution of the QR code, one of the CV rates (Conversion Rate: number of achievements/total number of opportunities to see information) used in access analysis, which is a soft endpoint, is set as the primary evaluation item.

Secondary

MeasureTime frame
-HPV vaccination rate for first-year junior high school students in 2023 The rationale for setting: Although it is a hard endpoint, obtaining results takes more than one year. -The number of accesses/distributions of QR codes adjusted by the Geographical Deprivation Index (ADI) The rationale for setting: ADI is used to adjust for differences in vaccination coverage across districts. ADI-adjusted HPV vaccination coverage The odds ratio for HPV vaccination coverage in 7th grade in 2022 and 2023
