“…The level of interest or salience may explain why subjects 50 years and older were more likely to respond to the survey than younger ones. In Canada, people 50 years of age and older are more likely to be vaccinated against influenza than younger ones [ 21 ]. Although one web-based survey about knowledge of arts education reported that participants 50 years and older were significantly more likely than their younger counterparts to respond [ 31 ], many others reported no difference in response rates by age [ 10 , 12 , 14 ].…”

“…Influenza vaccination is strongly recommended in people working in healthcare facilities and an increasing number of facilities require employees to be vaccinated as a condition of employment or to be vaccinated or wear a surgical mask while providing care to patients during the influenza season. Despite evidence supporting vaccination against influenza for healthcare workers to protect their vulnerable patients [ 18 , 19 ], only about 50% are vaccinated annually in Canada [ 20 , 21 ]. Meanwhile, vaccine hesitancy and refusal appears to be increasing [ 22 ], with adverse events being a top concern of vaccine hesitant people.…”

BackgroundWeb-based surveys have become increasingly popular but response rates are low and may be prone to selection bias. How people are invited to participate may impact response rates and needs further study as previous evidence is contradictory. The purpose of this study was to determine whether response to a web-based survey of healthcare workers would be higher with a posted or an emailed invitation. We also report results of the pilot study, which aims to estimate the percentage of adults vaccinated against influenza who report recurrent systemic adverse events (the same systemic adverse event occurring successively following receipt of influenza vaccines).MethodsThe pilot study was conducted in November 2016 in Toronto, Canada. Members of a registry of adults (18 years and older and predominantly healthcare workers) who volunteered to receive information regarding future studies about influenza were randomly assigned to receive either an email or postal invitation to complete a web-based survey regarding influenza vaccinations. Non-respondents received one reminder using the same mode of contact as their original invitation.ResultsThe overall response rate was higher for those sent the invitation by email (34.8%) than by post (25.8%; p < 0.001) and for older versus younger participants (ptrend < 0.001). Of those who responded, 387/401 had been vaccinated against influenza at least once since adulthood. Of those responding to the question, 70/386 (18.1%) reported a systemic adverse event after their most recent influenza vaccine including 22 (5.7%) who reported a recurring systemic event. Systemic adverse events were reported more often by males 18–49 years old than by other groups (p = 0.01). Recurrent systemic adverse events were similar by age and sex with muscle ache being the most commonly reported recurrent reaction. More respondents who reported only a local adverse event (93.1%) planned to be vaccinated again next year than those with a systemic adverse event (69.7%; p = 0.04).ConclusionsIn this convenience sample of registry volunteers, response rates were generally low, but were higher for the emailed than posted invitations and for older than younger adults.

“…28 A cross-sectional study of immunization among health-care professionals revealed a 16% increase in HCW influenza immunization after the introduction of vaccinate-or-mask influenza prevention policies in British Columbia and the Horizon Health Network. 4 Areas without such policies saw a decrease in influenza immunization of 1% over the course of the 2012-2013 season. 4 There is otherwise very little evaluative data about HCW immunization rates in these provinces.…”

“…2 Despite this recommendation, influenza vaccination coverage among Canadian HCW remains below the established target of 80%. 3,4 Voluntary programs with educational interventions, extensive publicity campaigns, accessible vaccination via mobile immunization carts and vaccination champions, prizes for HCW and for hospital leaders based on institutional influenza vaccination rates, and required declination signature forms have been demonstrated to improve vaccine coverage, but none of these interventions have been successful in achieving target coverage rates. [5][6][7][8] Responding to suboptimal coverage rates, some jurisdictions introduced condition-of-service policies, which require employees to comply with occupational health policy to protect the patient population.…”

Influenza can be potentially fatal to vulnerable populations, particularly those in the hospital. Canada's National Advisory Committee on Immunization recommends that health-care workers (HCW) be immunized against influenza partly to avoid infecting high-risk populations. However, influenza immunization rates among HCW remain suboptimal. In 2012, health authorities across British Columbia (B.C.) implemented a province-wide influenza prevention policy requiring HCW to either be immunized or wear a mask when in patient-care areas during the influenza season. This paper describes the second of two studies focused on what was learned from years 2 and 3 of the policy. A case study approach was used to examine this policy implementation event. Qualitative data were collected through key documents and key informant interviews with members of leadership teams responsible for policy implementation. Framework analysis and Prior's approach were used to analyze data from interviews and documents, respectively. Policy implementation varied by geographic region and gaps persist in immunization tracking and discipline for noncompliance. Debate regarding the scientific evidence used to support the policy fuels resistance from particular groups. Despite these challenges, findings suggest that the policy has been habituated, largely due to consistent policy objectives. This study emphasizes the importance of ongoing inter-professional and cross-sectoral program evaluation. While adherence may be routine for many, implementation processes must continue to respond to contextual issues to narrow the gap in policy implementation and to continue to engage stakeholders to ensure compliance.

“…Annual influenza vaccinations are advocated for HCWs in many European countries, such as the UK, Germany, France and Spain, and HCWs in the medical field receive vaccinations more often than the general population, with percentages ranging from 15.6% to 63.2% 13 . The rate of vaccination is even stronger in Canada, ranging from 50% to 69% 14 and in Australia, up to 50% 15 . The Italian Ministry of Health, in agreement with international guidelines, annually recommends vaccination for seasonal influenza to all healthcare workers (HCWs) 16 .…”
