Voluntary reporting of employee influenza vaccination rates by acute care hospitals in Iowa: the impact of a four year provider-based statewide performance improvement project

Objective

In 2006 a voluntary, provider-based project was initiated to improve influenza vaccination rates among healthcare workers (HCWs) employed by acute care hospitals in Iowa. The statewide vaccination target was 95% by 2010. Data from the first four influenza seasons (2006-2007, 2007-2008, 2008-2009 and 2009-2010) are presented.

Methods

A website was used to submit and circulate hospital-specific influenza vaccination rates. Rates were fed back to participating hospitals from the outset and hospital-specific rates made publicly available for the last two influenza seasons.

Results

Hospital participation rates ranged from 86% in season 1 to 100% in the subsequent three seasons. Statewide median hospital employee vaccination rates trended upward from 73% in season 1 to 93% in season 4. By season 4, 35% of participating hospitals had reached or exceeded a 95% vaccination rate. In season 4 the mean employee vaccination rate of 19 hospitals reporting use of a mandatory vaccination policy was 96% vs. 87% in the 64 hospitals not using such policies.

Conclusion

Over a 4 year period, while participating in a provider-based, voluntary project, acute care hospitals in Iowa reported significantly improved seasonal influenza vaccination rates among their employees.     

‘Closing the gap’: Evaluating the success of non-mandatory strategies for influenza vaccination of Victorian healthcare workers

IntroductionWhile annual influenza vaccination of healthcare workers (HCWs) is recommended, uptake is often suboptimal. We sought to evaluate influenza vaccination uptake by HCWs in Victorian public healthcare facilities, where non-mandatory programs are used.MethodsAll participating facilities completed an annual survey (2014–2019) recording HCW influenza vaccination status. Uptake in high-risk departments (emergency and intensive care units) was evaluated for the 2019 season.ResultsThe proportion of vaccinated HCWs increased annually, from 72.2% (2014) to 87.7% (2019), with pre-set targets generally achieved. In 2019, 110,324 HCWs in 107 facilities were vaccinated (87.7%). Of those without documented vaccination, 7591 (6.0%) declined and 7906 (6.3%) had unknown status. Uptake was higher in high-risk departments (91.4%).ConclusionIncreasing annual influenza vaccination uptake by HCWs in Victorian public healthcare facilities has been achieved in the context of performance monitoring targets. Small proportions declined or had unknown status. Future policies should focus on these HCWs.     

Voluntary reporting of health care personnel seasonal influenza vaccination rates and the impact of universal policies in Illinois hospitals

Objective

In 2009, voluntary public reporting of hospital health care personnel (HCP) vaccination rates began in Illinois. We describe our experience over 3 influenza seasons and examine the impact universal policies have had on performance.

Methods

A secure website was used to report monthly HCP vaccination rates by each participating hospital. Overall and individual hospital performance was publicly reported each month.

Results

In the first two seasons, there were 11 hospitals reporting with an average end of season rate of 76% (2009–2010) and 81% (2010–2011). In the 2011–2012 season, there were 22 hospitals reporting, 9 of which had a new universal policy for HCP influenza vaccination. The average 2011–2012 end of season rate was 72% for hospitals with a voluntary program and 95% for hospitals with a universal policy. HCP were also vaccinated earlier in the influenza season when a universal policy was in place, providing greater benefit over time.

Conclusion

Public reporting of HCP influenza vaccination rates may contribute to implementation of universal employee vaccination policies. Hospitals with universal policies have higher vaccination rates than those with voluntary vaccination programs.     

Influenza vaccination of future healthcare workers: A cross-sectional study of uptake,knowledge and attitudes

Promotional campaigns recommend immunisation against influenza in healthcare workers (HCWs) but the uptake in this group remains low. We conducted a survey study during the 2008–2009 influenza vaccination period amongst future HCWs to quantify uptake and identify barriers to immunisation. Overall uptake was 8.0% (95% CI 5.9–10.8%), which is lower than the uptake amongst current HCWs (13.4%) and short of current government targets (75%). Knowledge about influenza was good but insufficient to encourage HCWs to get vaccinated. Promotional campaigns are needed that emphasise the role of vaccination in personal and patient protection.     

Motivating factors for high rates of influenza vaccination among healthcare workers

Background

Recent guidance from related regulatory agencies and medical societies supports mandatory vaccination of healthcare workers (HCW) against influenza. At St. Jude Children's Research Hospital, a pediatric oncology referral center, more than 90% of HCWs receive vaccine each year without a policy mandating immunization. Factors associated with HCW uptake of influenza vaccines have not previously been evaluated in a high compliance rate setting.

Methods

A structured, anonymous, electronic questionnaire was distributed in August 2010 to employees (HCW and non-HCW). Demographics, prior receipt of influenza vaccines, reasons for acceptance or refusal of seasonal and 2009 H1N1 pandemic vaccine, and attitudes on mandatory vaccination were assessed.

Results

95.0% of 925 HCWs and 63.1% of all 3227 qualifying employees responded to the survey. 93.8% and 75.2% of HCW reported receiving seasonal and 2009 H1N1 influenza vaccines, respectively, in the 2009-2010 season. Benefits to self and/or patients were cited as the most frequent reasons for accepting seasonal (83.5% and 78.3%, respectively) and 2009 H1N1 (85.9% and 81.1%, respectively) vaccination. 36.6% of HCWs opposed mandating influenza vaccination; 88.2% and 59.9% of whom reported receiving the seasonal and 2009 H1N1 influenza vaccines, respectively. Violation of freedom of choice and personal autonomy were the most frequently reported reasons for opposition.

Conclusion

In this cohort of HCWs with a high influenza vaccination rate, realistic assessments of the potential benefits of vaccination appear to have driven the choice to accept immunization. Despite this, mandating vaccination was viewed unfavorably by a significant minority of vaccinated individuals. Employee concerns over autonomy should be addressed as institutions transition to mandatory vaccination policies.     

Willingness of healthcare workers to accept voluntary stockpiled H5N1 vaccine in advance of pandemic activity

Healthcare workers may be at risk during the next influenza pandemic. Priming with stockpiled vaccine may protect staff and reduce nosocomial transmission. Despite campaigns to increase seasonal influenza vaccine coverage, uptake among healthcare workers is generally low; creating uncertainty whether they would participate in pre-pandemic vaccine programmes. We conducted a cross-sectional questionnaire survey of healthcare workers in a UK hospital during, and 6 months after, a period of media reporting of an H5N1 outbreak at a commercial UK poultry farm. A total of 520 questionnaires were returned, representing 20% of frontline workforce. More respondents indicated willingness to accept stockpiled H5N1 vaccine during the period of media attention than after (166/262, 63.4% vs. 134/258, 51.9%; p = 0.009). Following multivariate analysis, factors associated with willingness to accept H5N1 vaccine included: previous seasonal vaccine (OR 6.2, 95% CI 3.0–12.8, p < 0.0001), awareness of occupational seasonal vaccine campaigns (OR 2.2, 95% CI 1.4–3.5, p = 0.001), belief that seasonal vaccine benefits themselves (OR 2.5, 95% CI 1.6–4.0, p < 0.0001) or the hospital (OR 3.6, 95% CI 2.3–5.8, p < 0.0001), belief that pandemic risk is high/moderate (OR 14.1, 95% CI 7.6–26.1, p < 0.0001) and would threaten healthcare workers (OR 2.9, 95% CI 1.8–4.5, p < 0.0001). Those who would not accept vaccine (220 respondents, 42.7%) if offered before the pandemic do not perceive pandemic influenza as a serious threat, and have concerns regarding vaccine safety. A majority of healthcare workers are amenable to accept stockpiled H5N1 vaccine if offered in advance of pandemic activity.     

Factors associated with caregivers’ hesitancy to vaccinate children against influenza: A cross-sectional survey in China

BackgroundSeasonal influenza can cause serious harm to children under five years of age, while caregivers are still hesitant to vaccinate children against influenza. This study aimed to investigate caregivers’ hesitancy regarding influenza vaccination and assess the associated factors.MethodsFrom August to October 2019, a cross-sectional survey was conducted in ten provinces in China. The questionnaire collected information about sociodemographic characteristics and caregivers’ knowledge, perceptions and attitudes toward influenza vaccination. Caregivers were identified as not hesitating, hesitating or refusing to vaccinate children. Multinomial logistic regression was adopted to determine factors related to vaccine hesitancy based on the 3C model with three dimensions namely complacency, convenience and confidence.ResultsA total of 6668 valid questionnaires were collected, among which 38.57% did not hesitate to vaccinate children against influenza, 56.03% were hesitant, and 5.40% refused. Multinomial logistic regression showed that caregivers perceiving high importance (AOR = 0.68 for hesitancy; 0.15 for refusal), safety (AOR = 0.42; 0.46) or efficacy (AOR = 0.73; 0.65) of influenza vaccination, knowing children as a priority group (AOR = 0.80; 0.48), and trusting vaccination advice from medical staff (AOR = 0.65; 0.51) had lower odds of hesitancy or refusal. Those considering price as a hindering factor had higher odds of hesitancy (AOR = 1.66) or refusal (AOR = 1.47), and those viewing time or distance as a hindering factor (AOR = 1.45) or having heard of vaccine-related negative information (AOR = 1.78) had higher odds of hesitancy. Sociodemographic characteristics were associated with vaccine hesitancy or refusal, and the associations varied for hesitators and refusers.ConclusionA large proportion of caregivers in China reported their hesitancy for influenza vaccination, and the associated factors of such hesitancy were complicated. Health professionals are recommended to spread relevant scientific knowledge and give vaccine-related suggestions to caregivers in doctor visits to promote caregivers’ trust in influenza vaccination and therefore expand childhood vaccine coverage.     

Determination of factors required to increase uptake of influenza vaccination among hospital-based healthcare workers

A questionnaire study was performed in all eight University Medical Centers in The Netherlands to determine the predictors of influenza vaccination compliance in hospital-based healthcare workers (HCWs). Demographical, behavioural and organisational determinants were assessed based on behavioural and implementation models. Multivariable regression analysis was applied to assess the independent predictors for influenza vaccine uptake. Age >40 years, the presence of a chronic illness, awareness of personal risk and awareness of risk of infecting patients, trust in the effectiveness of the vaccine to reduce the risk of infecting patients, the HCWs' duty to do no harm and their duty to ensure continuity of care, finding vaccination useful despite the constant flow of visitors and having knowledge of the Health Council's advice, social influence and convenient time for vaccination were all independently associated with vaccine uptake. The accuracy of the prediction model was very high (area under the receiver operating curve: 0.95). Intervention programmes to increase influenza vaccine uptake among HCWs should target the relevant determinants identified in this study.     

Are medical residents a "core group" for future improvement of influenza vaccination coverage in health-care workers? A study among medical residents at the University Hospital of Palermo (Sicily)

Despite international recommendations, vaccination coverage among European healthcare workers, including physicians, is widely recognized as unsatisfactory. In order to plan tailored vaccination campaigns and increase future coverage, we investigated reasons for refusing vaccination and determinants associated with influenza vaccine uptake among young health care workers.A survey was carried out during September and October 2010 on medical residents attending post-graduate Schools of the Medical Faculty at the University of Palermo (Italy). Each participant completed an anonymous web-based questionnaire including items on demographic and occupational characteristics, knowledge, attitudes and behaviours with regard to influenza and influenza vaccination, and main sources of information.A total of 202 (66.9%) out of 302 medical residents participated in the survey. During the 2009-2010 influenza vaccine campaign, 44 residents (21.8%) were vaccinated against seasonal influenza and 84 (41.6%) against pandemic influenza A (H1N1) 2009. For the impending 2010-2011 influenza season, 45 (22.3%) stated their intention to get vaccinated against seasonal influenza, 40 (19.8%) were uncertain and 117 (57.9%) were opposed. Considering themselves to be a high risk group for developing influenza was significantly associated with vaccination against both 2009-2010 seasonal (adj-OR = 1.46; 95% CI = 1.05-2.04) and pandemic A (H1N1) influenza (adj-OR 1.38; 95% CI = 1.08-1.75). Intention to get vaccinated against 2010-2011 seasonal influenza was significantly more frequent in participants who had a high perception of efficacy/safety (adj-OR = 1.49; 95% CI = 1.05-2.12). After adjusting for confounding, vaccinations against seasonal 2009-2010 influenza, pandemic influenza A (H1N1) 2009 and seasonal 2010-2011 influenza were significantly more frequent in residents who were vaccinated against influenza at least once in the previous five influenza seasons.Influenza vaccination among medical residents appears to be habitual, with little comprehension of the rationale and logic for vaccination, including the need to be vaccinated to protect patients from nosocomial influenza infection. Our study suggests the importance of prioritizing residents for vaccination campaigns, as they represent “the future” and include a core group that habitually accepts vaccination.     

Positive attitudes of French general practitioners towards A/H1N1 influenza-pandemic vaccination: A missed opportunity to increase vaccination uptakes in the general public?

Attitudes of general practitioners (GPs) towards A/H1N1 pandemic vaccination are unknown. We conducted a cross-sectional survey with computer-assisted telephone interviewing in the French Regional Panel of General Practices from June 16 to September 22, 2009. Of 1434 respondents representative of GPs in four French regions, 885 (61.7%) were willing to accept A/H1N1 pandemic vaccination for themselves. The personal history of seasonal flu vaccination was the strongest independent predictive factor of willingness to accept A/H1N1 pandemic vaccination (p < .0001). GPs receiving seasonal vaccines every year were more likely to accept A/H1N1 pandemic vaccination than those who were never vaccinated in the prior 3 years (adjusted OR = 4.38; 95% CI, 2.44–4.67). Willingness to accept pandemic vaccination was also significantly associated with being on call for emergencies; positive attitudes towards other protective measures against A/H1N1 influenza virus in the practice; and a higher readiness to provide additional consultations in response to the pandemic. In conclusion, GPs showed a high acceptability of A/H1N1 pandemic vaccination. GPs’ involvement in the mass vaccination campaign, which has been neglected by French public health authorities, may have increased uptake rates in the general public.     

Variations in reason for intention not to vaccinate across time,region, and by race/ethnicity,NIS-Teen (2008–2016)

Background

Human papillomavirus (HPV) vaccination is expected to reduce HPV-related disease and cancer in the US. However, many parents are hesitant to obtain the vaccine for their children. The purpose of this study is to examine how the reasons for refusing the HPV vaccine vary across regions of the US, across time, and by race/ethnicity.

Vaccine hesitancy and healthcare providers

While most people vaccinate according to the recommended schedule, this success is challenged by individuals and groups who delay or refuse vaccines. The aim of this article is to review studies on vaccine hesitancy among healthcare providers (HCPs), and the influences of their own vaccine confidence and vaccination behaviour on their vaccination recommendations to others.The search strategy was developed in Medline and then adapted across several multidisciplinary mainstream databases including Embase Classic & Embase, and PschInfo. All foreign language articles were included if the abstract was available in English.A total of 185 articles were included in the literature review. 66% studied the vaccine hesitancy among HCPs, 17% analysed concerns, attitudes and/or behaviour of HCPs towards vaccinating others, and 9% were about evaluating intervention(s). Overall, knowledge about particular vaccines, their efficacy and safety, helped to build HCPs own confidence in vaccines and their willingness to recommend vaccines to others. The importance of societal endorsement and support from colleagues was also reported.In the face of emerging vaccine hesitancy, HCPs still remain the most trusted advisor and influencer of vaccination decisions. The capacity and confidence of HCPs, though, are stretched as they are faced with time constraints, increased workload and limited resources, and often have inadequate information or training support to address parents’ questions. Overall, HCPs need more support to manage the quickly evolving vaccine environment as well as changing public, especially those who are reluctant or refuse vaccination. Some recommended strategies included strengthening trust between HCPs, health authorities and policymakers, through more shared involvement in the establishment of vaccine recommendations.     

Communicating and enhancing teachers’ attitudes and understanding of influenza using refutational text

Influenza is an important public health issue and schools play an important part in preventing influenza outbreaks. However, little is known about teachers’ knowledge and attitudes toward influenza and vaccination. The purposes of this project were to assess preservice and early career teachers’ knowledge and attitudes of influenza, evaluate the effectiveness of a refutational text on increasing teachers’ attitudes towards and knowledge of influenza and vaccination, and evaluate the effects of participant epistemology, motivation, and cognitive engagement on influenza attitudes and knowledge. We implemented an experimental intervention with 64 pre-service and early career teachers on the effects of a refutational text in remedying influenza misconceptions. Teachers in this sample have vaccination rates (36% received five vaccines in a five-year period) consistent with other US adults. Pre-intervention knowledge scores were moderate and attitudes were slightly positive. Positive attitudes were correlated with increased vaccination. We found refutational texts are effective in eliciting more positive attitudes toward influenza vaccination. We found cognitive engagement was positively correlated to change in attitude. Refutational texts provide an effective mode of influenza and vaccination education.     

Reflections on the influenza vaccination of healthcare workers

Despite all that is known about the dangers of nosocomial transmission of influenza to the vulnerable patient populations in our healthcare facilities, and the benefits of the influenza vaccination, the low rates of influenza vaccination among healthcare workers (HCWs) internationally shows no sign of significant improvement. With the current voluntary 'opt-in' programmes clearly failing to adequately address this issue, the time has undoubtedly come for a new approach to vaccination to be implemented. Two different approaches to vaccination delivery have been suggested to rectify this situation, mandatory vaccination and 'opt-out' declination forms. It is suggested, however, that these two approaches are inadequate when used by themselves. In order to protect the most vulnerable patients in our healthcare facilities as best we can from serious harm or death caused by nosocomial transmission of influenza, while at the same time respecting HCWs autonomy, and in many jurisdictions, the related legal right to refuse medical treatment, it is recommended that 'op-out' declination forms should be used in conjunction with restricted mandatory vaccination. This 'combined' approach would allow any HCW to refuse the influenza vaccination, but would make the influenza vaccination a mandatory requirement for working in areas where the most vulnerable patients are cared for. Those HCWs not willing to be vaccinated should be required to work in other areas of healthcare.
