Factors influencing human papillomavirus school-based immunization in Alberta: A mixed-methods study protocol

Abstract

More than 1,300 Canadians are diagnosed with cervical cancer annually, which is nearly preventable through human papillomavirus (HPV) immunization. Across Canada, coverage rates remain below the 90% target set out by the Action Plan for the Elimination of Cervical Cancer in Canada (2020–2030). To support this Plan, the Canadian Partnership Against Cancer has commissioned the Urban Public Health Network (UPHN) to coordinate a quality improvement project with Canada’s school-based HPV immunization programs. In Alberta, the UPHN partnered with Alberta Health Services (AHS) for this work. This study has one overarching research question: what are parent/guardian and program stakeholder perceived barriers, enablers and opportunities to immunization for youth as part of the school-based HPV immunization program in Alberta? This study uses a mixed-methods sequential explanatory design. A survey will be emailed to a sample of Albertans with children aged 11–17 years. Questions will be based on a Conceptual Framework of Access to Health Care. Subsequent qualitative work will explore the survey’s findings. Parents/guardians identifying as vaccine hesitant in the survey will be invited to participate in virtual, semi-structured, in-depth interviews. Stakeholders of the school-based immunization program will be purposively sampled from AHS’ five health zones for virtual focus groups. Quantitative data will be analyzed using SAS Studio 3.6 to carry out descriptive statistics and, using logistic regression, investigate if Framework constructs are associated with parents’/guardians’ decision to immunize their children. Qualitative data will be analyzed using NVivo 12 to conduct template thematic analysis guided by the Framework. Study results will provide insights for Alberta’s public health practitioners to make evidence-informed decisions when tailoring the school-based HPV immunization program to increase uptake in vaccine hesitant populations. Findings will contribute to the national study, which will culminate in recommendations to increase HPV immunization uptake nationally and progress towards the 90% coverage target.

Individual and Geospatial Determinants of Health Associated With School-Based Human Papillomavirus Immunization in Alberta: Population-Based Cohort Study

“…By using an integrated knowledge translation approach, the co-design team strives to shorten the typical 17-year research evidence-to-innovation gap, integrating study findings into public health planning to reach the 90% immunization target by 2025. Notably, these results will be supplemented with information on barriers and facilitators of the school-based HPV immunization program from the perspective of parents and guardians, as well as program leaders and front-line providers, through a CPAC-funded study being conducted by members of the co-design team [ 15 ].…”

“…In Alberta, the Gardasil vaccine was originally offered to female individuals in grade 5 in 2008 ( Figure 1 [ 15 ]) [ 16 ]. The original schedule consisted of 3 doses administered over a 6-month period.…”
