About this study

Official title: Comparing the Use of a Mobile App for Surveillance of Adverse Events Following Influenza Immunization to a Web-Based Platform: a Randomized Controlled Trial

Methods Study Procedures A two-centred randomized control trial (RCT) was conducted to evaluate the use of safety reporting via a mobile app compared to safety reporting via web-based CANVAS notifications amongst individuals receiving the influenza vaccine from October 6 to November 29, 2020 during the seasonal influenza vaccine campaign in Ottawa and Vancouver, Canada.

Individuals were recruited at the time of receiving their influenza vaccine. Eligibility criteria included the ability to speak English or French, having an active email address and telephone number, and being immunized with the seasonal influenza vaccine.

Randomization After study enrollment, participants were randomized to receive the online safety survey either through the mobile app or emailed a link to the online survey using a four-block randomization design.

Web-based notification arm All participants randomized to the web-based notification arm received the following web-based CANVAS notifications. Briefly, participants received an email notifying them of their registration in the study. Eight days following their influenza vaccine, participants received an email with the survey link asking them to complete their online influenza vaccine safety survey. Participants received a reminder email on day 11 if they did not complete their survey. Further details on CANVAS surveillance and description of the questionnaire can be found here.

Mobile app arm Participants randomized to the mobile app arm, received an email asking them to download the app and activate their account. Users who did not activate their account after 48 hours received a reminder email. Participants who activated their accounts, could spontaneously report an adverse event through the app, and were also notified of the day 8 survey through the app.

Eight days following their vaccination mobile app participants who activated their account received a push notification on their phone to complete their survey. A reminder push notice was sent out on day 11 to participants that had not yet competed the day 8 survey. On November 16, 2020 (mid-way through the recruitment period), additional email reminders in the mobile app arm were implemented on days 2, 4 and 6 to remind participants to register for the app. All participants received a day 8 email directing them to use their CANImmunize account to complete their influenza vaccine survey. Access to the survey link also was available in the email reminder.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Useability

    Following completion of the safety survey, all participants were sent a separate link by email to complete a user experience survey. Participants were asked about their history of participating in the flu vaccine safety survey and whether they previously used the CANImmunize app. Using a Likert scale, participants were asked questions on (i) perceived ease of use, (ii) perceived usefulness, (iii) their attitudes and intention of use towards the platform and (iv) questions pertaining to vaccine confidence and safety.

    Measured: through study completion - average of 4 months

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Useability (time frame: through study completion - average of 4 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT05794113, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
