PRomoting Older Adults' Pneumococcal Vaccination Through Education and Learning

Not Applicable

Completed

• Conditions: Pneumococcal Vaccine Attitude; Pneumococcal Vaccine Uptake; Pneumococcal Vaccine Knowledge; Vaccination Willingness
• Interventions: Other: Web-based educational video on pneumococcal vaccination; Other: Reminder email to be vaccinated

• Registration Number: NCT06234683
• Lead Sponsor: University of Ottawa

Brief Summary

The goal of this trial is to compare the effect of a web-based educational video about pneumococcal vaccines and a reminder email to get vaccinated (intervention) with a reminder email alone (comparator) in adults aged 65 or older living in any Canadian province who reported not having received a pneumococcal vaccine.

The main questions this trial aims to answer are:

1. does the educational intervention improve pneumococcal vaccine uptake,

2. does the educational intervention improve willingness to be vaccinated,

3. does the educational intervention improve knowledge of pneumococcal vaccination,

4. and does the educational intervention improve attitudes towards pneumococcal vaccines/vaccination?

Eligible participants who provide electronic consent will:

1. fill out a web-based baseline survey,

2. receive access to the educational video (if assigned to the intervention group),

3. receive an email reminder to be vaccinated (both groups),

4. and fill in a web-based follow-up survey.

Detailed Description

This research project is a web-based randomized controlled trial (RCT), targeting adults aged 65 years and older across all Canadian provinces. The primary objectives of this study are twofold. Firstly, it aims to assess the participants' knowledge, barriers, facilitators, and willingness to receive the pneumococcal vaccine at baseline. Secondly, it aims to evaluate the impact of a video-led educational intervention on pneumococcal vaccine literacy, willingness to be vaccinated, and the actual uptake of the vaccine. To this end, participants will be recruited through various online channels. Only individuals who have not received the pneumococcal vaccine will be considered eligible for inclusion. For the second objective, participants will be randomly assigned to either the intervention group (short video on pneumococcal vaccination) or the control group (reminder to receive a pneumococcal vaccine). Consenting participants will be required to complete two surveys: one at baseline and another approximately six months post-intervention. These surveys will provide valuable data for analyzing the effectiveness of the educational intervention in improving participants' knowledge, willingness to be vaccinated, and the actual uptake of the pneumococcal vaccine. Findings from this research will contribute to the understanding of factors influencing pneumococcal vaccine decision-making among older adults, ultimately informing strategies to enhance vaccine uptake and public health outcomes in this population.

Primary Outcome Measures

Name	Time	Method
Pneumococcal vaccine uptake measured using a web-based follow-up survey four to six months post-randomization	4-6 months	Participants will be asked at follow-up whether they received a pneumococcal vaccine since the last survey (yes/no/do not know).

Secondary Outcome Measures

Name	Time	Method
Change in pneumococcal vaccination willingness, measured using web-based surveys (one at baseline and one four to six months post-randomization)	4-6 months	Participants will be asked at baseline and follow-up whether they would be willing to receive a pneumococcal vaccine (yes/no/do not know).
Change in pneumococcal vaccine knowledge measured using web-based surveys (one at baseline and one four to six months post-randomization)	4-6 months	Participants will be asked about their vaccine knowledge at baseline and follow-up (yes/no/do not know).
Change in pneumococcal vaccine attitudes measured using web-based surveys (one at baseline and one four to six months post-randomization)	4-6 months	Participants will be asked about their vaccine attitudes using Likert-type questions at baseline and follow-up. The response options are on a 5-point Likert scale that ranges from a value of 1 for strongly disagree to a value of 5 for strongly agree. Higher scores indicate stronger agreement with the statement and with the outcome.
