Clinical Trial Summary

A multi-faceted knowledge translation intervention - The CARD (C-Comfort, A-Ask, R-Relax, D-Distract) System - was developed to improve the vaccination experience of students at school. CARD is a framework for delivering vaccinations that is student-centred that promotes coping. This study will examine the feasibility of CARD implementation procedures and measures in the school vaccination program in Calgary, Alberta for use in a larger cluster trial.


Clinical Trial Description

Vaccination is estimated to have saved more lives in Canada over the last 50 years than any other single intervention and is considered one of the most important advances in the prevention of disease. One major drawback of vaccination, however, is that the usual route of administration involves a painful needle injection. In students undergoing school-based mass vaccinations, vaccine injections frequently cause sever distress and fainting, with some serious injuries resulting from fainting. Concerns about pain and/or needle fear are also directly responsible for vaccine refusal in this population.

An evidence based clinical practice guideline for mitigating vaccine injection pain, fear and fainting has been developed, however, it is not yet implemented across different school-based vaccination settings and students are not benefiting from the research evidence. In a prior small-scale project, investigators developed and implemented a multi-faceted knowledge translation intervention - The CARD (C-Comfort, A-Ask, R-Relax, D-Distract) System - in some schools in a small public health region in Niagara, Ontario. CARD is a framework for delivering vaccinations that is student-centred and promotes coping. It integrates recommendations from the guideline in two separate components of the vaccination delivery program: 1) pre-vaccination day preparation, and 2) vaccination day activities. Investigators found preliminary evidence of acceptability, appropriateness, satisfaction and clinical effectiveness of CARD when used in grade 7 students in Niagara.

In this study, investigators plan to determine the feasibility of implementing CARD in a diverse and more complex public health region in Calgary, Alberta. Specifically, investigators will determine recruitment rates, adherence to CARD protocol, response rates for questionnaires, acceptability, appropriateness (fit), and satisfaction. The results will inform a future cluster trial. ;
