Characteristics of immunisation support programmes in Canada: a scoping review and environmental scan

OBJECTIVE

To identify, characterise and map the existing knowledge about programmes that provide immunisation support to Canadians and barriers and facilitators to their delivery.

DESIGN

Scoping review and environmental scan.

INTRODUCTION

Vaccine hesitancy may be associated with unmet support needs of individuals. Immunisation support programmes that provide multicomponent approaches can improve vaccine confidence and equitable access.

INCLUSION CRITERIA

Canadian programmes that focus on providing information about immunisation for the general public, but excluding articles targeting health professionals. The primary concept involves mapping the characteristics of programmes and our secondary concept examines barriers and facilitators to programme delivery.

METHODS

The Joanna Briggs Institute (JBI) methodology guided this review, reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. A search strategy was developed and translated for six databases in November 2021 (updated October 2022). Unpublished literature was identified through the Canadian Agency for Drugs and Technologies in Health Grey Matters checklist and other relevant sources. Stakeholders (n=124) from Canadian regional health authorities were also contacted by email for publicly accessible information. Two independent raters screened and extracted data from identified material. Results are presented in tabular form.

RESULTS

The search strategy and environmental scan resulted in 15 287 sources. A total of 161 full-text sources were reviewed after applying eligibility criteria, resulting in 50 articles. Programmes were delivered in multiple Canadian provinces, focusing on various vaccine types. All programmes aimed to increase vaccine uptake and were mostly provided in person. Multidisciplinary delivery teams based on collaborations among multiple entities were credited as a facilitator to programme delivery across settings. Limitations on programme resources, attitudes of programme staff and participants, and systems organisation were identified as barriers to delivery.

CONCLUSIONS

This review highlighted characteristics of immunisation support programmes across various settings and described multiple facilitators and barriers. These findings can inform future interventions that aim to support Canadians in making decisions about immunisation.

Meeting Patients Where They Are: A Nurse-Driven Quality Improvement Project to Provide Influenza Vaccinations in the Emergency Department

INTRODUCTION

Influenza is highly contagious, vaccine-preventable, and may result in significant morbidity and mortality. While vaccination is the primary protection against influenza, vaccination rates remain low. Traditionally, primary care clinics, retail pharmacies, and public health departments offer influenza vaccines. However, offering influenza vaccines in new settings may increase their availability to the public and increase community uptake. This project aimed to add emergency departments as a new influenza vaccine location to increase the number of vaccines distributed during the 2020 to 2021 influenza season.

METHODS

Adult patients discharged from 24 emergency departments were included in this pre- post-intervention project. A nurse-driven order set was established to enhance efficiency. Education materials (scripting, fliers, etc.) were developed to help nurses feel comfortable with vaccine information.

RESULTS

Nurses indicated that education helped increase their belief that influenza vaccination was important. After completing the educational material, a higher number of nurses agreed that it was necessary to encourage others to be vaccinated (P < 0.05). Moreover, emergency department influenza vaccinations increased significantly throughout the 2020 to 2021 influenza season. Nurses across all 24 hospitals administered 2002 vaccines during this season compared to 9 during the previous year's season.

DISCUSSION

The project demonstrated that delivering influenza vaccinations in emergency departments is challenging yet achievable. Educational offerings were valuable resources to increase nurses' knowledge and positive attitudes about providing influenza vaccines to patients. Further studies regarding how vaccinations could be provided in more emergency departments and alternative care sites, such as urgent care and clinics other than primary care providers, are needed.

Attitudes Toward Influenza Vaccination Administration in the Emergency Department Among Patients: A Cross-Sectional Survey

INTRODUCTION

Influenza is a serious, vaccine-preventable illness. The current vaccination rates in Canada are below target rates, highlighting the potential need for more convenient ways to receive vaccinations. Wait times to be seen in Canadian emergency departments are escalating, and using the time spent waiting to offer and administer an influenza vaccine could potentially improve ease of access to immunization for some Canadians.

METHODS

The aim of this cross-sectional study was to gauge public interest and identify perceived barriers and facilitators to influenza vaccine availability in a Canadian emergency and trauma center. Anonymous questionnaires were completed by a convenience sample of adult patients classified as low acuity (n = 151) as 1 arm of a 2-arm study.

RESULTS

Of the unvaccinated patients, 34.6% expressed willingness to be vaccinated in the emergency department. The patients who had received a vaccine in the previous year were significantly more willing to accept the vaccine in the emergency department (χ² [1] = 23.78, P < 0.001). The 3 top factors associated with having received vaccination in the previous year include trust in vaccine information (χ² [2] = 27.34, P < 0.001), immunity preferences (χ² [2] = 32.25, P < 0.001), and beliefs about efficacy (χ² [2] = 44.90, P < 0.001).

DISCUSSION

Patients classified as low acuity were supportive of ED influenza vaccination. In addition, some of the unvaccinated participants had unmet education needs (ie, regarding trustworthy sources of vaccine information, immunity, and vaccine efficacy) that would require addressing before they would likely consider receiving influenza vaccination in future during their ED visit.

Attitudes Toward Influenza Vaccination Administration in the Emergency Department Among Health Care Providers: A Cross-Sectional Survey

INTRODUCTION

Influenza is a burdensome and vaccine-preventable infectious disease. Lack of time was reported as a common barrier by Canadians who did not receive their influenza vaccine. Increasing convenient access to vaccination increases uptake, and a potential setting for vaccine administration is the emergency department, where long wait times are common.

METHODS

A cross-sectional survey to gauge health care provider support and perceived barriers and facilitators to delivering influenza vaccine was conducted at 1 emergency and trauma center in Halifax, Nova Scotia. Anonymous questionnaires were completed by a convenience sample of emergency nurses, physicians, and paramedics (n = 82).

RESULTS

In total, 86% (n = 68) of health care providers supported vaccination in the emergency department when sufficient staffing and resources were available. When asked to consider implementation of influenza vaccination in the emergency department based on current staffing and resources, only 59% (n = 48) supported making vaccination available. Most surveyed health care providers preferred screening for vaccination at triage (57%) and supported a nurse-initiated protocol for vaccine administration (74%). After Bonferroni correction, there was no significant association between preference for when to vaccinate and being a nurse or physician (χ²(2) = 6.208, P = 0.05). The highest risk patient groups with the lowest provider endorsement of vaccination were people involved in poultry culling (77%) and pregnant women (83%).

DISCUSSION

Surveyed health care providers were supportive of ED influenza vaccination. However, this study revealed additional barriers that need to be addressed to effectively launch such a program.
