Vaccination against influenza among Lebanese health care workers in the era of coronavirus disease 2019

BACKGROUND

Health-care workers (HCWs) are at a higher occupational risk of contracting and transmitting influenza. Annual vaccination is an essential tool to prevent seasonal influenza infection. However, HCWs vaccine hesitancy remains a leading global health threat. This study aims to evaluate the flu vaccination coverage rates among Lebanese HCWs and to assess their knowledge, attitudes, practices, perceived barriers, and benefits toward the flu vaccine during the COVID-19 pandemic. In addition, we sought to identify the factors associated with flu vaccine uptake.

METHODS

A cross-sectional study using an online survey was conducted in Lebanon among HCWs between 14 and 28 October 2020. Multivariable logistic regression was carried out to identify the factors associated with influenza vaccine uptake.

RESULTS

A total of 560 HCWs participated in the survey of whom 72.9% were females, and 53.9% were aged between 30-49 years. Regarding Flu vaccination uptake, the rate has risen from 32.1% in 2019-2020 to 80.2% in 2020-2021 flu season. The majority of HCWs had a good knowledge level and a positive attitude toward flu vaccination. Regarding their practices, less than 50% of HCW were currently promoting the importance of getting the flu vaccine. The majority (83.3%) ranked the availability of a sufficient quantity of vaccines as the most significant barrier to flu vaccination. The main perceived flu vaccination benefits were enhancing patient safety, minimizing the viral reservoir in the population, decreasing hospital admission, and avoiding influenza and COVID-19 co-infection. The odds of influenza vaccine uptake was lower in unmarried compared to married HCWs (OR = 0.527, CI (0.284-0.978). However, HCWs having received the influenza vaccine in the previous season (OR = 6.812, CI (3.045-15.239)), those with good knowledge level (OR = 3.305, CI (1.155-9.457)), low perceived barriers (OR = 4.130, CI (1.827-9.334)) and high perceived level of the benefits (OR = 6.264, CI (2.919-13.442)) of the flu vaccination were found more prone to get the flu vaccine.

CONCLUSION

Flu vaccination uptake has increased among HCWs during the 2020-2021 flu season compared with the previous one. Continuing education as well as ensuring free, equitable, and convenient access to vaccination are still required to increase the annual flu vaccination uptake among HCWs.

An evaluation of influenza vaccine uptake in UK medical students

BACKGROUND

The annual influenza vaccination is recommended for all front-line healthcare workers in the UK and is a crucial way of reducing mortality for vulnerable patient groups. However, to date the UK government has never explicitly monitored influenza vaccine uptake in medical students. This is important to ascertain, as students regularly move between clinical areas and are both a perfect vector for the spread of influenza and at an increased risk of contracting influenza themselves.

AIMS

This service evaluation was designed to evaluate the effectiveness of an influenza vaccination programme in one UK medical school and make recommendations to increase vaccination rates in the future.

METHODS

This service evaluation collected data about medical student uptake of influenza vaccination in one UK medical school. Two hundred and fifty-one students at different course stages completed questionnaires, answering questions on vaccination status and Likert-scale 'belief' questions to assess the subjective reasons behind vaccine refusal.

RESULTS

There was a substantial difference between year group cohorts (~20%), with significantly higher vaccination rates in the preclinical year group. Two significant negative predictors of vaccination were found (P < 0.001), related to scepticism over the effectiveness of the vaccine and lack of convenient access to the vaccination. Results indicated that integrating information about the influenza vaccine into the curriculum would reduce lack of knowledge over the efficacy of the vaccine. The centralization of vaccination programmes at mandatory university-based learning events would mitigate against the problem of diversity of vaccination locations and lack of central accountability.

CONCLUSIONS

The results of this service evaluation provide significant predictors of vaccination status for medical students and potential occupational health interventions to improve vaccine uptake in this group.

Use of a comprehensive program to review religious and personal seasonal influenza vaccination exemption requests by healthcare personnel

OBJECTIVE

Vanderbilt University Medical Center (VUMC) requires that all faculty and staff receive the seasonal influenza vaccine annually or receive an approved vaccine exemption, either for a medical or deeply held religious or personal belief. We sought to understand the underlying principles behind these exemption requests and their interaction with a multidisciplinary exemption review process.

DESIGN

All of the personal and religious exemption requests at VUMC for 3 consecutive influenza seasons from 2015 to 2018 were analyzed, categorizing these requests by 1 of 12 standardized employee categories and 1 of 18 unique reasons for vaccine exemption.

SETTING

Tertiary-care academic medical center.

PARTICIPANTS

Healthcare personnel (HCP).

RESULTS

Among the 3 influenza seasons, 1.1%-2.1% of all VUMC HCP requested religious or personal exemption from vaccination. The frequency of religious and personal exemption approval increased annually from 296 of 452 (65.5%) to 196 of 248 (80.2%) to 283 of 323 (87.6%) over the 3 seasons, representing a statistically significant increase each year. Of the 5 most common reasons against vaccination, 4 were explicitly religious in nature; the most common reason was that the "body is a temple or sacred." Nonclinical staff submitted the most religious and personal exemption requests of any job category, submitting approximately one-third of all requests every year.

CONCLUSIONS

These results demonstrate how detailed the personal or religious convictions behind vaccine avoidance can be among HCP and how vaccine avoidance stems from much more than simple misinformation regarding vaccination. The intersection between misinformation and personal or religious beliefs provides a unique opportunity to address HCP opinions toward vaccination in an exemption and appeals process like the one described here.

A new strategy to promote flu vaccination among health care workers: Molinette Hospital's experience

RATIONALE, AIMS, AND OBJECTIVES

Seasonal flu represents a major public health issue, especially for health care workers (HCWs). WHO highlights the need of higher awareness and flu vaccine coverage among HCWs. In Europe the coverage is less than 30-40%. Italy reports some of the lowest rates. The paper aims to illustrate the 2017/2018 flu vaccination campaign within Molinette, the third Italian hospital for dimensions, to provide inputs about strategies for increasing HCWs coverage. The campaign objective was to increase the administered doses at least of 30%.

METHODS

The intervention included informational material, direct educational sessions for workers, extension of the access time to Occupational Medicine Service, elimination of the reservation requirement, composition of "moving vaccination units" (MVUs), and organisation of vaccination sessions within departments.

RESULTS

In 2017/2018, 593 doses were administered. The doses percentage change between 2017/2018 and 2016/2017 vaccination seasons was +46.06%, while it was +84.74% compared with the previous 5-year period mean. The majority was administered by Occupational Medicine Service, while 6.75% by MVUs. Among the total doses, 72.68% were administered to workers, 13.49% to residents, 6.75% to students, and 7.08% to "other". So, 7.68% of total workforce was vaccinated. Only 0.3% of vaccinated people presented mild adverse reactions.

CONCLUSIONS

A combined campaign, that includes actions for education, increase of awareness, improved access to facilities and active offers to workers has potentiality but there is still work to do. The vaccination increase was determined mostly by the re-organization of the occupational medicine, while the MVUs were useful to HCWs of detached offices.

Influenza Vaccination Rates Among Parents and Health Care Personnel in a German Neonatology Department

The influenza vaccination is recommended for all German pregnant women and health care personnel (HCP). We are the first to publish vaccination rates of mothers of hospitalized newborns and HCP in neonatal units. Between September 2016 and March 2017, data were collected in our level-III neonatology department in this descriptive multidisciplinary study, using an anonymous questionnaire. As a result, 513 persons were asked to participate, including 330 parents and 183 HCP. We received an 80.3% (412/513) response rate, 87.3% (288/330), and 67.8% (124/183) from parents and HCP, respectively. Ten percent (16/160) of mothers and 4.7% (6/127) of fathers had been vaccinated in 2016–2017 and 54.4% (87/160) mothers and 52.2% (66/127) fathers ever in their lifetime. In 2016–2017, 51.2% (21/41) of physicians had been vaccinated, 25.5% (14/55) of nurses, and 50.0% (14/28) of other staff members. When comparing those who had more than five influenza vaccinations in their life time, physicians were at 43.9% (18/41) versus nurses at 10.9% (6/55) (p < 0.01), and other HCP at 7.4% (2/27) (p < 0.01). The influenza vaccine uptake rate of 10% in mothers of hospitalized neonates is disappointingly low, resulting in 90% of hospitalized neonates being potentially vulnerable to influenza infection at a time where the risk for influenza-related complication can be severe.

Pattern of exposure to information and its impact on seasonal influenza vaccination uptake in nurses

BACKGROUND

Uptake of annual influenza vaccination of healthcare workers (HCWs) varies, and remains at a suboptimal level in many countries. As HCWs are often exposed to a variety of information about vaccination, the pattern of exposure may impact their decision; this deserves further investigation.

METHODS

Practising nurses in Hong Kong were invited to participate in an anonymous online survey in February 2016, after the winter seasonal peak. The questionnaire covered demographics, work nature and experiences, vaccination uptake history and reasons for vaccination decisions. Two behavioural categories for access to information were defined - passive exposure to information and active information-seeking - differentiated by the source, type and nature of information accessed. Chi-squared test, Mann-Whitney U-test and logistic regression were performed to compare vaccinated and unvaccinated nurses.

RESULTS

In total, 1177 valid returns were received from nurses. The median age of respondents was 32 years and 86% were female. The overall vaccination rate was 33%. Passive exposure to information from the workplace, professional body and social network was not predictive of vaccination decision, but passive exposure to information from mass media was predictive [odds ratio (OR) 1.78]. Active information-seeking, such as consulting a senior (OR 2.46), organizing promotional activities (OR 2.85) and undertaking an information search (OR 2.43), was significantly associated with increased vaccination uptake. A cumulative effect could be demonstrated for active information-seeking (OR 1.86), but not for passive exposure to information.

CONCLUSION

The current strategy of promotions and campaigns for seasonal influenza vaccination in HCWs may not be effective in increasing vaccination coverage. Measures targeting information-seeking behaviours may serve as an alternative approach.

Knowledge of and Attitudes to Influenza Vaccination among Community Pharmacists in Catalonia (Spain). 2013-2014 Season: A Cross Sectional Study

Annual recommendations on influenza seasonal vaccination include community pharmacists, who have low vaccination coverage. The aim of this study was to investigate the relationship between influenza vaccination in community pharmacists and their knowledge of and attitudes to vaccination. An online cross-sectional survey of community pharmacists in Catalonia, Spain, was conducted between September and November 2014. Sociodemographic, professional and clinical variables, the history of influenza vaccination and knowledge of and attitudes to influenza and seasonal influenza vaccination were collected. The survey response rate was 7.33% (506 out of 6906); responses from 463 community pharmacists were included in the final analyses. Analyses were performed using multivariable logistic regression models and stepwise backward selection method for variable selection. The influenza vaccination coverage in season 2013–2014 was 25.1%. There was an association between vaccination and correct knowledge of the virus responsible for epidemics (adjusted Odds Ratio (aOR) = 1.74; 95% CI 1.03–2.95), recommending vaccination in the postpartum (aOR = 3.63; 95% CI 2.01–6.55) and concern about infecting their clients (aOR = 5.27; 95% CI 1.88–14.76). In conclusion, community pharmacists have a very low influenza vaccination coverage, are not very willing to recommend vaccination to all their customers but they are concerned about infecting their clients.

Stepwise intervention including 1-on-1 counseling is highly effective in increasing influenza vaccination among health care workers

BACKGROUND

The influenza vaccination rate among health care workers (HCWs) remains suboptimal. We attempted to increase vaccine uptake in HCWs by nonmandatory measures, including 1-on-1 counseling.

METHODS

In 2015 we used a stepwise approach including (1) text messaging on the last day of the vaccination period, (2) extending the vaccination period by 3 days, (3) education for the low uptake group, and (4) 1-on-1 counseling for unvaccinated HCWs after the 3 interventions.

RESULTS

There were 1,433 HCWs included. By the end of the initial 3 days, the uptake rate was 80.0% (1,146/1,433). During an extension for a further 3 days, 33 additional HCWs received the vaccine. One month after starting the vaccination, 90.1% (1,291/1,433) of the HCWs were vaccinated, but this included only 76.1% (210/276) of the doctors (lowest among HCWs). After 3 educational presentations targeted at the unvaccinated doctors, no additional individuals were vaccinated in the following 2 weeks. After 1-on-1 counseling for unvaccinated HCWs, the overall vaccination rate increased to 94.7% (1,357/1,433) in 2015, higher than in the previous year (82.5%, P < .001). Of the unvaccinated doctors, 63.2% (43/68) were vaccinated, therefore achieving 92.4% (255/276) compliance, higher than the 56.5% in the previous year (152/269, P < .001).

CONCLUSIONS

Stepwise intervention including 1-on-1 counseling is effective in increasing influenza vaccination rates among HCWs.

Determinants of seasonal influenza vaccination in pregnant women in Valencia, Spain

BACKGROUND

In most countries the coverage of seasonal influenza vaccination in pregnant women is low. We investigated the acceptance, reasons for rejection and professional involvement related to vaccine information in pregnant women in Valencia, Spain.

METHODS

Observational retrospective study in 200 pregnant women, 100 vaccinated and 100 unvaccinated, were interviewed during the 2014/2015 vaccination campaign. Electronic medical records, immunization registry and telephone interviews were used to determine reasons for vaccination and immunization rejection.

RESULTS

40.5% of pregnant women in the health department were vaccinated. The midwife was identified as source of information for 89% of women. The vaccine was rejected due to low perceptions of risk of influenza infection (23%), lack of information (19%), considering the vaccine as superfluous (16%), close proximity of delivery date (13%) and fear of side effects (12%).

CONCLUSION

Pregnant women in Spain declined to be vaccinated due to under-estimation of the risk of contracting or being harmed by influenza, and lack of information. Interventions aiming to optimize vaccination coverage should include information addressing the safety and effectiveness of the current vaccine together with improved professional training and motivation.

Influenza Vaccination Coverage Rates, Knowledge, Attitudes, and Beliefs in Jordan: A Comprehensive Study

Influenza vaccination is the most effective method in preventing influenza and its complications. This study's objectives were to investigate the vaccination coverage and frequency and to assess knowledge, attitudes, and practices toward influenza vaccination in Jordan during the year 2012 and the 5 years preceding it. Additionally, it aimed at identifying the barriers and motivations to receive the vaccine and the factors contributing to its uptake. In May 2012, a self-administered cross-sectional survey was distributed to 3,200 adults conveniently selected across Jordan to explore influenza vaccination status, knowledge, attitudes, and practices toward the influenza vaccine. The survey response rate was 98.3%. The overall coverage rate of seasonal influenza vaccination ranged from 9.9% to 27.5%. Results of the univariate analysis revealed that males, participants older than 45 years, business owners, and university students or graduates were more likely to take the vaccine. Healthcare workers (HCW) showed higher rates than non-HCW and those with concomitant chronic diseases were more committed to receive the vaccine. Knowledge about the influenza vaccine is considered high in the Jordanian population. Fear from side effects was the major barrier, while the fear of the virus spread and outbreak was the major reason to receive the vaccine. The coverage rates were low in Jordan compared to other countries. The need for influenza vaccine campaigns and on-going education in Jordan health schools is crucial to increase the rate and remove misconceptions and negative attitudes toward vaccination.

Immunization of Health-Care Providers: Necessity and Public Health Policies

Health-care providers (HCPs) are at increased risk for exposure to vaccine-preventable diseases (VPDs) in the workplace. The rationale for immunization of HCPs relies on the need to protect them and, indirectly, their patients from health-care-associated VPDs. Published evidence indicates significant immunity gaps for VPDs of HCPs globally. Deficits in knowledge and false perceptions about VPDs and vaccines are the most common barriers for vaccine uptake and may also influence communication about vaccines between HCPs and their patients. Most countries have immunization recommendations for HCPs; however, there are no universal policies and significant heterogeneity exists between countries in terms of vaccines, schedules, frame of implementation (recommendation or mandatory), and target categories of HCPs. Mandatory influenza immunization policies for HCPs have been implemented with high vaccine uptake rates. Stronger recommendations for HCP immunization and commitment at the level of the health-care facility are critical in order to achieve high vaccine coverage rates. Given the importance to health, mandatory immunization policies for VPDs that can cause serious morbidity and mortality to vulnerable patients should be considered.

Seasonal Influenza Vaccination amongst Medical Students: A Social Network Analysis Based on a Cross-Sectional Study

Introduction

The Chief Medical Officer for England recommends that healthcare workers have a seasonal influenza vaccination in an attempt to protect both patients and NHS staff. Despite this, many healthcare workers do not have a seasonal influenza vaccination. Social network analysis is a well-established research approach that looks at individuals in the context of their social connections. We examine the effects of social networks on influenza vaccination decision and disease dynamics.

Methods

We used a social network analysis approach to look at vaccination distribution within the network of the Lancaster Medical School students and combined these data with the students’ beliefs about vaccination behaviours. We then developed a model which simulated influenza outbreaks to study the effects of preferentially vaccinating individuals within this network.

Results

Of the 253 eligible students, 217 (86%) provided relational data, and 65% of responders had received a seasonal influenza vaccination. Students who were vaccinated were more likely to think other medical students were vaccinated. However, there was no clustering of vaccinated individuals within the medical student social network. The influenza simulation model demonstrated that vaccination of well-connected individuals may have a disproportional effect on disease dynamics.

Conclusions

This medical student population exhibited vaccination coverage levels similar to those seen in other healthcare groups but below recommendations. However, in this population, a lack of vaccination clustering might provide natural protection from influenza outbreaks. An individual student’s perception of the vaccination coverage amongst their peers appears to correlate with their own decision to vaccinate, but the directionality of this relationship is not clear. When looking at the spread of disease within a population it is important to include social structures alongside vaccination data. Social networks influence disease epidemiology and vaccination campaigns designed with information from social networks could be a future target for policy makers.

Knowledge of and attitudes to influenza in unvaccinated primary care physicians and nurses

Primary healthcare workers, especially nurses, are exposed to the vast majority of patients with influenza and play an important role in vaccinating patients. Healthcare workers’ misconceptions about influenza and influenza vaccination have been reported as possible factors associated with lack of vaccination. The objective of this study was to compare the characteristics of unvaccinated physicians and unvaccinated nurses in the 2011–2012 influenza season. We performed an anonymous web survey of Spanish primary healthcare workers in 2012. Information was collected on vaccination and knowledge of and attitudes to the influenza vaccine. Multivariate analysis was performed using unconditional logistic regression. We included 461 unvaccinated physicians and 402 unvaccinated nurses. Compared with unvaccinated nurses, unvaccinated physicians had more frequently received seasonal influenza vaccination in the preceding seasons (aOR 1.58; 95% CI 1.11–2.25), and more frequently believed that vaccination of high risk individuals is effective in reducing complications (aOR 2.53; 95% CI 1.30–4.95) and that influenza can be a serious illness (aOR 1.65; 95% CI 1.17–2.32). In contrast, unvaccinated physicians were less concerned about infecting patients (aOR 0.62; 95% CI 0.40–0.96). Unvaccinated nurses had more misconceptions than physicians about influenza and the influenza vaccine and more doubts about the severity of annual influenza epidemics in patients with high risk conditions and the prevention of complications by means of the influenza vaccination. For unvaccinated physicians, strategies to improve vaccination coverage should stress the importance of physicians as a possible source of infection of their patients. The effectiveness of influenza vaccination of high risk persons should be emphasized in nurses.

Australian Hajj pilgrims' infection control beliefs and practices: Insight with implications for public health approaches

BACKGROUND

Hajj is one of the largest annual mass gatherings around the world. Although the Saudi Arabian health authority recommends vaccination and other infection control measures, studies identified variable uptake of these measures among pilgrims, and the reasons behind this variability remain unclear. This qualitative study aimed to addresses this knowledge gap.

METHODS

In-depth interviews were conducted with pilgrims over 18 years of age.

RESULTS

A total of 10 participants took part in the study. There was low perception of the potential severity of respiratory conditions and the need for influenza vaccination during Hajj. Different attitudes were found by age group with elderly participants believing that they were under Allah's protection, and were fatalistic about the risk of illness. While younger participants described the impact infections would have on their worship. Facemask use was infrequent with discomfort; difficulty in breathing and a feeling of isolation were commonly cited barriers to use of facemasks. Participants accepted and trusted preventative health advice from travel agents and friends who had previously undertaken the Hajj more so than primary care practitioners.

CONCLUSIONS

This study extended our understanding of how health beliefs influence uptake of preventive measures during the Hajj, and the gaps in the provision of Hajj-specific health information to pilgrims.

Mandatory Influenza Vaccination of Healthcare Workers: A 5-Year Study

Background.

The rate of influenza vaccination among healthcare workers (HCWs) is low, despite a good rationale and strong recommendations for vaccination from many health organizations.

Objective.

To increase influenza vaccination rates by instituting the first mandatory influenza vaccination program for HCWs.

Design and Setting.

A 5-year study (from 2005 to 2010) at Virginia Mason Medical Center, a tertiary care, multispecialty medical center in Seattle, Washington, with approximately 5,000 employees.

Methods.

All HCWs of the medical center were required to receive influenza vaccination. HCWs who were granted an accommodation for medical or religious reasons were required to wear a mask at work during influenza season. The main outcome measure was rate of influenza vaccination among HCWs.

Results.

In the first year of the program, there were a total of 4,703 HCWs, of whom 4,588 (97.6%) were vaccinated, and influenza vaccination rates of more than 98% were sustained over the subsequent 4 years of our study. Less than 0.7% of HCWs were granted an accommodation for medical or religious reasons and were required to wear a mask at work during influenza season, and less than 0.2% of HCWs refused vaccination and left Virginia Mason Medical Center.

Conclusion.

A mandatory influenza vaccination program for HCWs is feasible, results in extremely high vaccination rates, and can be sustained over the course of several years.

Student Immunity Requirements of Health Professional Schools: Vaccination and Other Means of Fulfillment—United States, 2008

US health professional schools with student immunity requirements for recommended vaccines frequently accept evidence of immunity other than vaccination but vary widely on the types of evidence that are accepted. Exemptions for nonmedical reasons and, to a lesser extent, medical reasons are often obtainable by a student-written document.

A Successful Mandatory Influenza Vaccination Campaign Using an Innovative Electronic Tracking System

Background.

Although influenza vaccination of healthcare workers reduces influenza-like illness and overall mortality among patients, national rates of vaccination for healthcare providers are unacceptably low. We report the implementation of a new mandatory vaccination policy by means of a streamlined electronic enrollment and vaccination tracking system at the National Institutes of Health (NIH) Clinical Center.

Objective.

To evaluate the outcome of a new mandatory staff influenza vaccination program.

Methods.

A new hospital policy endorsed by all the component NIH institutes and the Clinical Center departments mandated that employees who have patient contact either be vaccinated annually against influenza or sign a declination specifying the reason(s) for refusal. Those who fail to comply would be required to appear before the Medical Executive Committee to explain their rationale. We collected in a database the names of all physician and nonphysician staff who had patient contact. When a staff member either was vaccinated or declined vaccination, a simple system of badge scanning and bar-coded data entry captured essential data. The database was continuously updated, and it provided a list of noncompliant employees with whom to follow up.

Results.

By February 12, 2009, all 2,754 identified patient-care employees either were vaccinated or formally declined vaccination. Among those, 2,424 (88%) were vaccinated either at the NIH or elsewhere, 36 (1.3%) reported medical contraindications, and 294 (10.7%) declined vaccination for other reasons. Among the 294 employees without medical contraindications who declined, the most frequent reason given for declination was concern about side effects.

Conclusions.

Implementation of a novel vaccination tracking process and a hospital policy requiring influenza vaccination or declination yielded dramatic improvement in healthcare worker vaccination rates and likely will result in increased patient safety in our hospital.

Receptivity to Mandatory Influenza Vaccination Policies for Healthcare Workers Among Registered Nurses Working on Inpatient Units

A survey that included questions about preferred methods of influenza prevention was completed by 513 registered nurses working on inpatient units. Vaccination was the preferred influenza prevention method among 83.0% of respondents. Of 506 respondents, 283 (56.0%) stated that mandatory influenza vaccination was appropriate for healthcare workers, and 394 (59.4%) of 512 RNs reported that they would support a policy requiring annual influenza vaccination for healthcare workers that allowed for informed declination.

Healthcare worker influenza vaccination in Oregon nursing homes: correlates of facility characteristics

OBJECTIVES

Nursing home (NH) employee influenza vaccination is associated with reductions in morbidity and mortality among residents. Little is known regarding associations between NH characteristics and employee influenza vaccination rates (EVRs). This study identifies NH characteristics that may be associated with EVRs.

DESIGN

Data on employee vaccination rates and programs were gathered from the Office for Oregon Health Policy and Research reports for 3 influenza seasons from 2009 to 2012 and merged with Online Survey, Certification, and Reporting files, from which facility characteristics were obtained. Market controls were obtained from the 2010 Area Health Resource File. Multivariate linear and logistic regression were used to model relationships between facility characteristics and EVR per facility per year, whether formal education for employees was conducted, and whether 2010, 2015, and 2020 Healthy People targets were met.

SETTING

Oregon nursing homes from 2009 to 2012.

PARTICIPANTS

NHs reporting sufficient data to calculate an EVR were included. Based on information obtained from 2009-2010, 2010-2011, and 2011-2012 surveys, EVRs were calculated for 113/140, 129/141, and 137/140 (81%, 91%, and 98% of) NHs, respectively.

MEASUREMENTS

Dependent variables were EVR per facility per year, whether formal education for employees was conducted, and whether 2010, 2015, and 2020 Healthy People targets were met. Independent variables included facility characteristics and market controls.

RESULTS

On average, chain-affiliated NHs had 9% higher EVRs (P = .01) and 73% higher odds of achieving 60% EVR (2010 target, P = .05) than free-standing NHs. For-profit NHs had, on average, 8% lower EVRs (P = .04) than not-for-profit NHs. Surprisingly, a 10% increase in proportion of Medicaid residents was associated with a 2% increase in EVR (P = .01) and higher odds of achieving 60% (odds ratio = 1.20, P = .004) and 70% (2015 target, odds ratio = 1.14, P = .05) EVR.

CONCLUSION

Given that NHs generally have low employee influenza vaccination rates, it may be necessary to target low-performing facilities to achieve substantial improvements. However, significant correlates of this study cannot be easily addressed by NH management or policymakers. Without policy change encouraging key components of vaccination programs, public reporting may be insufficient to improve EVRs.

Healthcare worker compliance with seasonal and pandemic influenza vaccination

Healthcare workers (HCWs) can be an important source of transmission of influenza to patients and family members, and their well-being is fundamental to the maintenance of healthcare services during influenza outbreaks and pandemics. Unfortunately, studies have shown consistently low levels of compliance with influenza vaccination among HCWs, a finding that became particularly pronounced during recent pandemic vaccination campaigns. Among the variables associated with vaccine acceptance in this group are demographic factors, fears and concerns over vaccine safety and efficacy, perceptions of risk and personal vulnerability, past vaccination behaviours and experience with influenza illness, as well as certain situational and organisational constructs. We report the findings of a review of the literature on these factors and highlight some important challenges in interpreting the data. In particular, we point out the need for longitudinal study designs, as well as focused research and interventions that are adapted to the most resistant HCW groups. Multi-pronged strategies are an important step forward in ensuring that future influenza vaccination campaigns, whether directed at seasonal or pandemic strains, will be successful in ensuring broad coverage among HCWs.

[Occupationally acquired infections among health care workers: Respiratory diseases]

INTRODUCTION

In some medical departments, healthcare workers (HCWs) are at risk for aerogene transmitted infectious diseases. Numerous fatal causalities were described in the international environment. For example fatal causalities during the SARS-Epidemic as well as cases of death caused by influenza.

METHODS AND RESULTS

Selective literature review of occupationally acquired aerogene infections like SARS-coronavirus, influenza virus, parainfluenza virus, RSV, adenovirus, tuberculosis as well as pertussis. Currently available data demonstrate that personal protective measures (e.g. appropriate use of hand washing and oronasal mask), as well as vaccinations (if available) reduces the risk for transmission of infectious diseases.

DISCUSSION

The risk for occupationally acquired infections is sometimes an unavoidable part of daily patient care. From occupational medicine point of view and for control of infectious diseases preventive measures should be implemented to provide the best possible protection of HCW involved. With regard to a possible pandemic (e.g. influenza pandemic) this procedure is absolutely required.

Examining the views of key stakeholders regarding the provision of occupational influenza vaccination for healthcare workers in Australia

Annual vaccination of hospital healthcare workers (HCWs) may be an effective measure to reduce the transmission of healthcare associated influenza. However, vaccine coverage rates among HCWs in most public Australian hospitals are below satisfactory for a number of reasons. This study aimed to examine the opinions of key health stakeholders on current issues regarding HCW influenza vaccination. A qualitative study involving semi-structured interviews was undertaken with key Australian health stakeholders representing different organizations and sectors involved in influenza vaccination and policy. Amongst the participants, there was overwhelming support for HCW influenza vaccination. They viewed vaccination as one of the most important preventive measures for healthcare associated influenza and generally agreed that vaccination of HCWs reduces the overall risk of transmission to patients. However, there were contradictory attitudes regarding the evidence available for justifying the impact of vaccinating HCWs against influenza. Amongst the stakeholders interviewed, there was support for continuing to promote influenza vaccination for HCWs via the conventional framework. Participants recommended that hospitals continue to use conventional, voluntary strategies to increase vaccine coverage such as education and mobile carts. Given that the World Health Organization has included HCWs as a target group for influenza vaccination, Australian hospitals may need to start considering the use of mandatory policies in the near future.

Knowledge of and attitudes to influenza vaccination in healthy primary healthcare workers in Spain, 2011-2012

Annual influenza vaccination is recommended for healthcare workers, but many do not follow the recommendation. The objective of this study was to investigate the factors associated with seasonal influenza vaccination in the 2011–2012 season. We carried out an anonymous web survey of Spanish primary healthcare workers in 2012. Information on vaccination, and knowledge and attitudes about the influenza vaccine was collected. Workers with medical conditions that contraindicated vaccination and those with high risk conditions were excluded. Multivariate analysis was performed using unconditional logistic regression. We included 1,749 workers. The overall vaccination coverage was 50.7% and was higher in workers aged ≥ 55 years (55.7%), males (57.4%) and paediatricians (63.1%). Factors associated with vaccination were concern about infection at work (aOR 4.93; 95% CI 3.72–6.53), considering that vaccination of heathcare workers is important (aOR 2.62; 95%CI 1.83–3.75) and that vaccination is effective in preventing influenza and its complications (aOR 2.40; 95% CI 1.56–3.67). No association was found between vaccination and knowledge of influenza or the vaccine characteristics. Educational programs should aim to remove the misconceptions and attitudes that limit compliance with recommendations about influenza vaccination in primary healthcare workers rather than only increasing knowledge about influenza and the characteristics of the vaccine.

Health care reform and influenza immunization

Health care reform calls for the nursing profession, with a focus on disease prevention and health restoration, to innovate and create new models of care that are client-centric, evidence-based, and cost-effective. To do so, nurses must develop a fundamentally different paradigm and epistemology. New care models are required that focus on issues such as evidence-based prevention. Among the prevention foci for hospitals are hospital-acquired infections, including influenza, which kills 36,000 Americans annually. One crucial step in eliminating hospital-acquired influenza is to require influenza vaccination of all health care workers. This article challenges nursing leadership to seize opportunities to lead health care initiatives and encourage courageous innovative actions that depart from old paradigms; these actions must be based on scientific evidence, reduce costs, and promote patient safety and quality care and outcomes.

Legal considerations surrounding mandatory influenza vaccination for healthcare workers in the United States

Recent years have brought increased focus on the desirability of vaccinating more healthcare workers against influenza. The concern that novel 2009 H1N1 influenza A would spark a particularly severe influenza season in 2009-2010 spurred several institutions and one state to institute mandatory vaccination policies for healthcare workers, and several new mandates have been introduced since then. Some healthcare workers, however, have voiced objections in the media and in legal proceedings. This paper reviews the characteristics of influenza and how it is transmitted in the healthcare setting; surveys possible constitutional, administrative, and common law arguments against mandates; assesses the viability of those arguments; and identifies potential new legal strategies to support influenza vaccine mandates. It is intended to assist those involved in the regulation and administration of public and private healthcare institutions who may be considering approaches to mandates but have concerns about legal challenges.

Seasonal influenza vaccination knowledge, risk perception, health beliefs and vaccination behaviours of nurses

The relationship between knowledge, risk perceptions, health belief towards seasonal influenza and vaccination and the vaccination behaviours of nurses was explored. Qualified nurses attending continuing professional education courses at a large London university between 18 April and 18 October 2010 were surveyed (522/672; response rate 77·7%). Of these, 82·6% worked in hospitals; 37·0% reported receiving seasonal influenza vaccination in the previous season and 44·9% reported never being vaccinated during the last 5 years. All respondents were categorized using two-step cluster analyses into never, occasionally, and continuously vaccinated groups. Nurses vaccinated the season before had higher scores of knowledge and risk perception compared to the unvaccinated (P<0·001). Nurses never vaccinated had the lowest scores of knowledge and risk perception compared to other groups (P<0·001). Nurses' seasonal influenza vaccination behaviours are complex. Knowledge and risk perception predict uptake of vaccination in nurses.

Development and testing of an instrument to assess nurses' knowledge, risk perception, health beliefs and behaviours related to influenza vaccination

AIMS AND OBJECTIVES

To develop an instrument to measure nurses' knowledge, risk perception and health beliefs towards influenza and influenza vaccination and their vaccination behaviours and evaluate its construct validity and internal consistency reliability.

BACKGROUND

Although instruments to assess predictors of nurses' vaccination behaviours have been developed, their validity and reliability have not been reported.

DESIGN

Instrument development and initial validity and reliability testing.

METHODS

The instrument was developed drawing on a literature review and expert consultation and was refined through pilot work. A cross-sectional survey using a revised version of the instrument was conducted among a convenience sample of 520 registered nurses (response rate 77.4%). Cronbach's alpha coefficient was calculated to determine internal consistency of the sub-scale in the instrument. Principal components analysis with varimax rotation was carried out to evaluate the instrument's construct validity and examine its internal structure.

RESULTS

Cronbach's alpha coefficients for the three newly developed scales ranged from 0.70-0.76. Principal components analysis produced a good fit and confirmed the internal design of the instrument. In the seasonal influenza knowledge sub-scale four factors explained 44.8% of the total variance; in the H1N1 knowledge sub-scale two factors explained 44.7% of the total variance. Three factors in the risk perception scale contributed 50.5% of the total variance and two factors in the vaccination behaviours scale contributed 62.1% of the total variance.

CONCLUSIONS

An instrument has been developed to assess nurses' knowledge, risk perception and health beliefs towards influenza and influenza vaccination and their vaccination behaviours. The instrument was valid and reliable for the setting where it was used.

RELEVANCE TO CLINICAL PRACTICE

This instrument could be used to assess nurses' knowledge, risk perception, health beliefs towards influenza and influenza vaccination and their vaccination behaviours. The three newly developed scales could also be used independently to measure variables influencing nurses' vaccination practices.

Knowledge, attitudes and perceptions of health professionals in relation to A/H1N1 influenza and its vaccine

OBJECTIVE

To determine the intention of health professionals, doctors and nurses, concerning whether or not to be vaccinated against A/H1N1 influenza virus, and their perception of the severity of this pandemic compared with seasonal flu.

MATERIAL AND METHODS

A cross-sectional study was carried out based on an questionnaire e-mailed to health professionals in public healthcare centres in Vitoria between 6 and 16 November 2009; the percentage of respondents who wanted to be vaccinated and who perceived the pandemic flu to carry a high risk of death were calculated.

RESULTS

A total of 115 people completed the questionnaire of whom 61.7% (n=71) were doctors and 38.3% (n=44) were nurses. Of these, 33.3% (n=23) of doctors and 13.6% (n=6) of nurses intended to be vaccinated (p=0.019). Even among those who considered themselves to be at a high risk, 70.6% (n=48) of doctors and 31.7% (n=13) of nurses participating in the study (p=0.001) planned to have the vaccination.

CONCLUSIONS

Most health professionals, and in particular nurses, had no intention to be vaccinated against A/H1N1 influenza virus at the beginning of the vaccination campaign.

Influenza vaccination among nursing professionals: reality and challenges

OBJECTIVE: To determine the profile, vaccination status and the motivating factors that lead nurses of a university hospital to get vaccinated against influenza in order to maximize coverage through adequate operational/educational strategies. METHODS: Cross-sectional descriptive study with a sample size of 265 nurses. RESULTS: Vaccination coverage was found to be 49.8% in 2009, 92.4% in 2010 and 95.4% in 2011. The professional profile with better adherence to vaccination was the mid level, female, 41-50 years, separated/divorced, not living with people susceptible to influenza, except chronic patient, also with more than one employment bond, placed at emergency where they often have contact with patients, trained and working for over 20 years, vaccinated in their own work sector, motivated by self-protection. CONCLUSION: The coverage percentage of 92.5% in 2010 and 95.4% in 2011, were considered exceptional within the current global reality. Educational actions within the institution created an incorporated culture of biosafety related to the topic.

Healthcare workers' duty concerns of working in the isolation ward during the novel H1N1 pandemic

AIMS AND OBJECTIVES

The aim was to explore healthcare workers' duty concerns in the isolation wards during the novel H1N1 pandemic.

BACKGROUND

Healthcare workers' willingness to work is a concern worldwide since SARS; Concerns related to work in the isolation wards among healthcare workers' who continue to work during the novel H1N1 pandemic is unknown. In the light of possible staff shortages, healthcare workers' duty concern is very important for planning the retention strategies.

METHOD

The qualitative study with individual interview of 10 healthcare workers (four physicians, three nurses and three healthcare assistances) working in isolation wards were conducted in mid June 2009 where pandemic alert level 6 was raised by WHO. Interviews were audio-taped, transcribed verbatim and then analysed using a thematic analysis approach.

RESULTS

All participants who were still working in the isolation wards during the novel H1N1 pandemic showed professional senses that were strongly related to the willingness to work. Their concerns in their duty including appreciation from the employers, efficacy and side effects of vaccination, frequent policy changes, unclear criteria of case management, poor facility layout, duty role stress were highlighted.

CONCLUSIONS

Further research should seek to provide in-depth specific concerns in each type of healthcare workers which is very important to keep adequate healthcare workers fighting against the infectious disease pandemic. Interesting results on the negative view towards the swine flu vaccination demonstrate more detailed evidence-based information about the vaccination is needed.

RELEVANCE TO CLINICAL PRACTICE

It is important for mangers to provide a support to healthcare workers during influenza pandemic by providing a clear guideline/policy for case management and demonstrating appreciation for the frontline healthcare workers to minimise the risk for high staff turnover rates.

The decision to receive influenza vaccination among nurses in North and South Dakota

OBJECTIVES

We examined the relationships between factors (intention, habit, facilitating conditions, and social, cognitive, and affective factors) and nurses' decisions about influenza vaccinations to understand why some get vaccinated while others do not.

DESIGN AND SAMPLE

In a descriptive correlational design, the Triandis model of interpersonal behavior was used to examine the decision of nurses to receive influenza vaccinations. Participants were a random sample (N=193) of registered nurses in North and South Dakota drawn from the respective state nursing licensing board lists.

MEASURES

Instrument construction and mail survey procedures followed Dillman's tailored design method.

RESULTS

The response rate exceeded 80%. The findings revealed significant, positive correlations among all model variables. Item analysis showed that false beliefs about influenza disease and vaccinations were prevalent and that there was a wide variation in employer support for nurses getting vaccinated.

CONCLUSIONS

Educational and social marketing strategies may improve nurse's knowledge about influenza disease and vaccine and increase vaccine uptake. Employers should be encouraged to promote and improve influenza vaccine accessibility in the workplace. Additional study is needed to understand how best to strengthen the influence of intention and habit on the decision of nurses to receive influenza vaccinations.

[Determinants of influenza vaccination in health staff: 2009-2010 season]

OBJECTIVES

To determine vaccination coverage against seasonal influenza and the new A (H1N1) influenza virus among healthcare personnel during the 2009-2010 season and to identify its determining factors.

METHODS

We performed a cross-sectional study among healthcare staff at the General University Hospital in Alicante (Spain) during the 2008-2009 and 2009-2010 influenza vaccination campaigns. The 2009-2010 vaccination campaign was subdivided into two phases. In the first phase, from 1st October to 19th November, 2009, the seasonal influenza vaccine was administered; in the second phase, from 16th November to 30th December, 2009, vaccination against the new A (H1N1) influenza virus was performed. Each of the vaccine programs was preceded by a specific vaccination promotion campaign. Healthcare staff were asked to complete a brief self-administered questionnaire containing a list of reasons for being vaccinated. Coverage during both vaccination campaigns was calculated, and the results, both overall and for each profession, were then compared using a Chi-square test.

RESULTS

Coverage against seasonal influenza was 31% and that against the new A (H1N1) influenza virus was 22.2% (p<0.05); these percentages were 36% and 34% respectively in medical personnel (NS), 33% and 24% respectively in nursing personnel (p<0.001), and 21% and 12% respectively in nursing assistants (p<0.001). The main reason given for being vaccinated was self-protection.

CONCLUSIONS

The low coverage achieved is a public health problem. Specific intervention programs should be implemented.
