Health behavior associated with influenza vaccination among healthcare workers in long-term-care facilities

A systematic review of barriers and enablers associated with uptake of influenza vaccine among care home staff

Barriers and enablers to vaccination of care home (CH) staff should be identified in order to develop interventions to address them that increase uptake and protect residents. We aimed to synthesis the evidence describing the barriers and enablers that affect the influenza vaccination uptake of care home (CH) staff.

METHOD

We searched PubMed, MEDLINE, EMBASE, CINAHL, PsycINFO, AMED, IBSS, SCOPUS to identify quantitative, qualitative or mixed-method studies. Data related to health or social care workers in CHs reported barriers or enablers were extracted and mapped to the Theoretical Domains Framework (TDF); the data within each domain were grouped and categorized into key factors affecting influenza vaccine uptake among CH staff.

RESULTS

We screened 4025 studies; 42 studies met our inclusion criteria. Thirty-four (81 %) were surveys. Five theoretical domains were frequently reported as mediators of influenza vaccine uptake: Beliefs about consequences (32 studies), Environmental context and resources (30 studies), Emotions (26 studies), Social influences (25 studies), Knowledge (22 studies). The low acceptance rate of the influenza vaccine among CH staff can be attributed to multiple factors, including insufficient understanding of the vaccine, its efficacy, or misconceptions about the vaccine (knowledge), perceiving the vaccine as ineffective and unsafe (beliefs about consequences), fear of influenza vaccine and its side effects (emotions), and experiencing limited accessibility to the vaccine (environmental context and resources).

CONCLUSION

Interventions aimed at increasing influenza vaccine uptake among CH staff should focus on addressing the barriers identified in this review. These interventions should include components such as enhancing knowledge by providing accurate information about vaccine benefits and safety, addressing negative beliefs by challenging misconceptions, managing concerns and fears through open communication, and improving accessibility to the vaccine through convenient on-site options. This review provides a foundation for the development of tailored Interventions to improve influenza vaccine uptake among CH staff.

Exploring COVID-19 education to support vaccine confidence amongst the general adult population with special considerations for healthcare and long-term care staff: A scoping review

Background

Despite the demonstrated efficacy of approved COVID-19 vaccines, high levels of hesitancy were observed in the first few months of the COVID-19 vaccines' rollout. Factors contributing to vaccine hesitancy are well-described in the literature. Among the various strategies for promoting vaccine confidence, educational interventions provide a foundationally and widely implemented set of approaches for supporting individuals in their vaccine decisions. However, the evidence around the measurable impact of various educational strategies to improve vaccine confidence is limited. We conducted a scoping review with the aim of exploring and characterizing educational interventions delivered during the pandemic to support COVID-19 vaccine confidence in adults.

Methods

We developed a search strategy with a medical information scientist and searched five databases, including Ovid MEDLINE and Web of Science, as well as grey literature. We considered all study designs and reports. Interventions delivered to children or adolescents, interventions on non-COVID-19 vaccines, as well as national or mass vaccination campaigns without documented interaction(s) between facilitator(s) and a specific audience were excluded. Articles were independently screened by three reviewers. After screening 4602 titles and abstracts and 174 full-text articles across two rounds of searches, 22 articles met our inclusion criteria. Ten additional studies were identified through hand searching. Data from included studies were charted and results were described narratively.

Results

We included 32 studies and synthesized their educational delivery structure, participants (i.e., facilitators and priority audience), and content. Formal, group-based presentations were the most common type of educational intervention in the included studies (75%). A third of studies (34%) used multiple strategies, with many formal group-based presentations being coupled with additional individual-based interventions (29%). Given the novelty of the COVID-19 vaccines and the unique current context, studies reported personalized conversations, question periods, and addressing misinformation as important components of the educational approaches reviewed.

Conclusions

Various educational interventions were delivered during the COVID-19 pandemic, with many initiatives involving multifaceted interventions utilizing both formal and informal approaches that leveraged community (cultural, religious) partnerships when developing and facilitating COVID-19 vaccine education. Train-the-trainer approaches with recognized community members could be of value as trust and personal connections were identified as strong enablers throughout the review.

PROTOCOL: Exploring education to support vaccine confidence amongst healthcare and long-term care staff amidst the COVID-19 pandemic: A protocol for a living scoping review

Despite the demonstrated effectiveness of vaccines, varying levels of hesitancy were observed among healthcare and long-term care workers, who were prioritized in the roll out of COVID-19 vaccines due to their high risk of exposure to SARS-CoV-2 transmission. However, the evidence around the measurable impact of various educational interventions to improve vaccine confidence is limited. The proposed scoping review is intended to explore any emerging research and experiences of delivering educational interventions to improve COVID-19 vaccine confidence among health and long-term care workforces. We aim to identify characteristics of both informal and formal educational interventions delivered during the pandemic to support COVID-19 vaccine hesitancy. Using the guidance outlined by the Joanna Briggs Institute, we intend to search five databases including, Ovid MEDLINE and Web of Science, as well as grey literature. We will consider all study designs and reports in an effort to include a breadth of sources to ensure our review will capture preliminary evidence, as well as more exploratory experiences of COVID-19 vaccine education delivery. Articles will be screened by three reviewers independently and the data will be charted, and results described narratively.

Health care provider trust in vaccination: a systematic review and qualitative meta-synthesis

BACKGROUND

Vaccine hesitancy is a growing issue globally amongst various populations, including health care providers. This study explores the factors that influence vaccine hesitancy amongst nurses and physicians.

METHODS

We performed a qualitative meta-synthesis of 22 qualitative and mixed-method studies exploring the factors that may contribute to vaccine hesitancy amongst nurses and physicians. We included all articles that mentioned any aspect of trust concerning vaccination, including how trust may influence or contribute to vaccine hesitancy in nurses and physicians.

RESULTS

Our findings revealed that vaccine hesitancy amongst nurses stemmed predominantly from two factors: distrust in health authorities and their employers, and distrust in vaccine efficacy and safety. Both nurses and physicians had a precarious relationship with health authorities. Nurses felt that their employers and health authorities did not prioritize their health over patients' health, provided inaccurate and inconsistent vaccine information, and were mistrustful of pharmaceutical company motives. Like nurses, physicians were also skeptical of pharmaceutical company motives when it came to vaccination. Additionally, physicians also held doubts regarding vaccine efficacy and safety.

CONCLUSIONS

The relationship health care providers or their patients have with health authorities and other providers regarding vaccination serves as unsystematic clinical experiences that may bolster vaccine hesitancy. Providing accurate and tangible information to emphasize the safety and efficacy of vaccines to health care providers may help address their specific concerns that may ultimately increase vaccine uptake.

Examining community pharmacists' intention to provide pharmacist-driven vaccination services: A structural equation modelling

BACKGROUND

The evidence of pharmacists' current involvement in vaccination services in low- and middle-income countries (LMICs) is uncertain. This study would be a first step to develop vaccination services by investigating community pharmacists' intention to be involved in PDV services not just during COVID-19 pandemic but also during standard service provision in Turkey which can be taken as an example across LMICs.

OBJECTIVE

Considering the efforts to empower community pharmacists in service provision, the goal of the present study was to develop a structural equation model to explain the "Pharmacist-Driven Vaccination Service Intention Model (PDV-SIM)" by using the theory of planned behavior (TPB).

METHODS

Based on the constructs of TPB, a measurement tool was developed. Sub-factors of PDV service intention was determined by conducting exploratory factor analysis (EFA). In the second step, confirmatory factor analysis (CFA) was conducted to prove the theoretical structure of the tool. Finally, a model explaining the relationship between observed variables, latent constructs from TPB was developed by SEM analysis.

RESULTS

In the proposed PDV-SIM, patient related attitude toward PDV services, attitude toward negative consequences of PDV services, and subjective norm about PDV services had an impact on the behavioral intention of community pharmacists. Nevertheless, professional development attitude toward PDV services and perceived behavioral control were not evaluated as determinants of the behavioral intention.

CONCLUSION

Results of this study revealed that TPB is appropriate for modelling PDV service intention of community pharmacists. This model can be utilized as a guide to potential pharmacy regulatory bodies and policy makers in their efforts to enable community pharmacists as vaccinators across LMICs.

Knowledge, Attitudes and Perception toward COVID-19 Vaccines among Adults in Jazan Province, Saudi Arabia

Background: Saudi Arabia is one of the countries that initiated early vaccination programs despite the global challenges concerning the availability of COVID-19 vaccines. Massive vaccination campaigns have been undertaken in the country; however, negative perception and hesitancy toward vaccines may exist which could reduce public response to vaccination. Further, studies evaluating the current perception and attitude toward COVID-19 vaccines are scarce. Thus, this study aims to assess the community attitudes and perceptions toward COVID-19 vaccines in Jazan Province, Saudi Arabia. Methods: A cross-sectional, retrospective study using an online questionnaire was conducted among the public in Jazan, the southern region of Saudi Arabia. General and demographic data were collected, and perception and attitude toward COVID-19 vaccines were evaluated. Results: Most participants in this study were female (67%) with a median age of 23 years. The majority held a bachelor’s degree, and they trusted the Saudi healthcare system. Our survey showed that 67% of the study participants had positive perceptions toward COVID-19 vaccines, a finding that is significantly associated with receiving the influenza vaccine in the past, the existence of trust on the current healthcare system and holding positive beliefs toward the effectiveness of the current COVID-19 vaccines in reducing the risk of infection, complication, and mortality. Conclusions: The proportion of the public in Jazan who believed in the COVID-19 vaccine effectiveness is not inferior from similar international reports. Thus, national awareness programs toward the effectiveness of the vaccine could be enhanced to accelerate vaccination coverage. Further, nationwide surveys are warranted to include larger populations from different communities to assess the overall perception toward COVID-19 vaccines in the whole country.

A qualitative meta-synthesis on how autonomy promotes vaccine rejection or delay among health care providers

In spite of the overwhelming evidence that highlights the effectiveness of routine vaccination, an increasing number of people are refusing to follow recommended vaccination schedules. While the majority of research in this area has focussed on vaccine hesitancy in parents, there is little research on the factors that promote vaccine hesitancy in health care providers (HCPs). Identifying factors that promote vaccine hesitancy in HCPs is essential because it may help broaden our understanding of vaccine hesitancy in patients. Therefore, the goal of this investigation was to review 21 studies and examine how professional autonomy and risk perception may promote vaccine acceptance, rejection and delay in physicians and nurses. We found that vaccine hesitant nurses and physicians shared similar views towards vaccines; both groups believed that their decision to vaccinate was separate from their role as an HCP. This belief comprised of three themes: decisional autonomy, personal risk perception and alternatives to vaccination. Both groups believed that mandatory vaccine policies reduced their ability to decide whether vaccination was in their best interests. We argue that decisional autonomy may weaken risk perception of disease, which in turn may encourage beliefs and behaviours that reinforce a 'hero persona' that reduces appropriate preventive and hygiene measures. We employ the Health Belief Model to discuss the crucial role that risk perceptions may play in reinforcing autonomy in vaccine hesitant physician and nurses. We conclude this paper by providing a set of recommendations that aim to improve the decision-making process surrounding mandatory vaccinations for HCPs.

To Get Vaccinated or Not? Psychological Safety as a Catalyst for the Alignment Between Individual Beliefs and Behavior

While many studies have investigated the consequences of psychological safety for behavior, there is little theorizing on the mechanisms that account for these effects. Since psychological safety makes individuals feel safe to express their true self, we argue that it should act as a catalyst for alignment between individual beliefs and behavior. Drawing on the reasoned action model, we postulate that psychological safety interacts with individuals’ attitudes and perceived norms in predicting intention and behavior. We tested our model with physicians’ influenza vaccination behavior. We surveyed 208 physicians from a Swiss hospital before and after the vaccination phase. Results show that the effect of attitude, but not perceived norm, on intention to get vaccinated was moderated by perceived psychological safety in the physicians’ team: High psychological safety strengthened the effect of physicians’ attitude on their intention, which in turn predicted actual vaccination behavior. We provide first evidence that high psychological safety may render individuals more comfortable to act in accordance with their attitudes. Depending on whether attitudes are in line with organizational goals, increasing psychological safety could facilitate positive or negative consequences. This more differentiated understanding of psychological safety can fruitfully inform both future research and organizational practice.

Change of Willingness to Accept COVID-19 Vaccine and Reasons of Vaccine Hesitancy of Working People at Different Waves of Local Epidemic in Hong Kong, China: Repeated Cross-Sectional Surveys

Vaccine hesitancy is among the major threats to the effectiveness of vaccination programmes. This study aimed to report the trend in response to willingness to accept the COVID-19 vaccine between two waves of the local epidemic and examine differences among occupations. Two cross-sectional surveys were conducted online during the first wave (February) and third wave (August to September) of the local epidemic in 2020. Acceptance of the COVID-19 vaccine was measured along with personal protection behaviours and occupations. A total of 2047 participants provided valid responses. The willingness to accept the COVID-19 vaccine among the participants was lower in the third wave (34.8%) than the first wave (44.2%). There were more concerns over vaccine safety in the third wave. Clerical/service/sales workers were less likely to accept the vaccine (adjusted odds ratio: 0.62, 95% confidence interval: 0.43–0.91). A high-level compliance of facemask wearing was found, and more people maintained social distancing and used alcohol hand rub in the third wave. Decreasing willingness to accept the COVID-19 vaccine may be associated with increasing concerns about vaccine safety and growing compliance of personal protection behaviours. The rush of vaccine development with higher risks of safety issues may jeopardize the public’s trust and lower uptake rates. Education and favourable policy should be provided to the general working population for the vaccination, especially for those who are not professional and are frequently exposed to crowds.

Organisational factors affecting performance in delivering influenza vaccination to staff in NHS Acute Hospital Trusts in England: A qualitative study

•

Wide variation in uptake of flu vaccine persists in English NHS hospitals.

•

Many factors of high uptake are linked to leadership and organisational culture.

•

Embedding the flu programme in well-being policy helps acceptability and adherence.

•

A supportive culture is likely to achieve higher uptake than a coercive one.

•

Middle managers’ facilitating role in delivering the programme is key to uptake.

Health care workers are a priority group for seasonal influenza vaccination, which is recommended by the World Health Organisation. There is a wide variation in uptake between and within countries. England has achieved 69.5% of health care workers vaccinated overall in 2017/18 across NHS acute and community health care settings, but it varies between Trusts from 50% to over 92.3%. While attitudinal factors have been well researched, there is limited evidence on organisational factors associated with high uptake. In England, most NHS Trusts are now implementing a similar range of interventions as part of their flu programme, and it remains unclear why performance remains so variable. This qualitative study is the first to explore reasons for this variation and provide recommendations for lower performing Trusts on how to improve. Fifty-seven interviews of managers and vaccinators were conducted in nine hospitals with flu vaccination uptake ranging from just over 55% to above 90%. Our study found that while Trusts deployed a wide range of both demand generating and supply interventions to increase uptake, there were marked differences in the organisational and delivery models utilised. Our study suggests that organisational culture was possibly the most important ingredient when trying to differentiate between high and low performing Trusts. We found that a positive culture aimed at fostering continuous improvement and favouring non-coercion on balance yielded more adherence from staff. Where influenza vaccination was embedded in the organisation wellbeing strategy, rather than executed as a siloed seasonal programme, this tended to foster good performance. Improving performance of influenza vaccination in health care workers will involve not only deploying the right interventions, and following “best practices”. It will require the adaptation of flu progamme delivery strategies to the organisation context, and embedding vaccination into the organisational culture, thus supporting the normalisation of yearly vaccination.

Seasonal influenza self-vaccination behaviours and attitudes among nurses in Southeastern France

BACKGROUND

Despite seasonal influenza vaccination (SIV) being recommended to healthcare professionals to protect themselves and their patients, uptake is low, especially among nurses. We sought to study self-vaccination behaviours, attitudes and knowledge about SIV among nurses in Southeastern France.

METHODS

A cross-sectional survey with community and hospital-based hospital nurses was conducted with the same standardised questionnaire. Multi-model averaging approaches studied factors associated with the following dependent variables: self-reported SIV uptake; and considering SIV a professional responsibility.

RESULTS

1539 nurses completed the questionnaire (response rate: 85%). SIV was the most frequently cited vaccine (49%) regarding nurses' unfavourable opinions towards specific vaccines. Thirty-four percent of nurses reported being vaccinated at least once during the 2015-2016 or 2016-2017 seasons. A lack of perceived personal vulnerability to influenza, a fear of adverse effects, and a preference for homeopathy constituted the main deterrents of SIV. Nurses held various misconceptions about the SIV, but 69% considered its benefits to be greater than its risks. The multi-model averaging approach showed that considering SIV as a professional responsibility was the main factor associated with SIV uptake among nurses (Nagelkerke's partial R-squared: 15%). This sense of responsibility was strongly associated with trust in various vaccine information sources.

CONCLUSION

Nurses had low SIV uptake rates and held various concerns and a lack of knowledge surrounding the vaccine. This is concerning considering the impact that these factors can have on nurses and patients' health, especially considering the increased role that nurses could have surrounding SIV in the near future.

Knowledge, Attitude, Awareness, and Barriers Toward Influenza Vaccination Among Medical Doctors at Tertiary Care Health Settings in Peshawar, Pakistan-A Cross-Sectional Study

Objective: This study intends to evaluate the knowledge, attitude and awareness of medical doctors toward influenza vaccination and the reasons for not getting vaccinated. Methods: A cross-sectional study was carried out among medical doctors in three major tertiary care health settings in Peshawar, Khyber Pakhtunkhwa (KP), Pakistan. A web-based, pre-tested questionnaire was used for data collection. Results: A total of (n = 300) medical doctors were invited, however only (n = 215) participated in the study with a response rate of 71.7%. Among the participants, 95.3% (n = 205) were males with a mean age of 28.67 ± 3.89 years. By designation, 121(56.3%) were trainee medical officers and 40 (18.6%) were house officers. The majority 102(47.4%) had a job experience of 1-2 years. Of the total sample, 38 (17.7%) doctors reported having received some kind of vaccination, whereas only 19 (8.84%) were vaccinated against influenza. The results identified that the major barriers toward influenza vaccinations included (1) Unfamiliarity with Influenza vaccination availability (Relative Importance Index RII = 0.830), (2) Unavailability of Influenza vaccines due to lack of proper storage area in the institution (RII = 0.634), (3) Cost of vaccine (RII = 0.608), and (4) insufficient staff to administer vaccine (RII = 0.589). Additionally, 156 (72.6%) of doctors were not aware of the influenza immunization recommendation and guidelines published by the Advisory Committee on Immunization Practices (ACIP) and Centre for Disease Control and Prevention (CDC). Physicians obtained a high score (8.27 ± 1.61) of knowledge and understanding regarding influenza and its vaccination followed by medical officers (8.06 ± 1.37). Linear Regression analysis revealed that gender was significantly associated with the knowledge score with males having a higher score (8.0± 1.39) than females (6.80 ± 1.61 β = -1.254 and CI [-2.152 to -0.355], p = 0.006). Conclusion: A very low proportion of doctors were vaccinated against influenza, despite the published guidelines and recommendations. Strategies that address multiple aspects like increasing awareness and the importance of the influenza vaccine, the international recommendations and enhancing access and availability of the vaccine are needed to improve its coverage and health outcomes.

Preventing Respiratory Viral Transmission in Long-Term Care: Knowledge, Attitudes, and Practices of Healthcare Personnel

OBJECTIVE

To examine knowledge and attitudes about influenza vaccination and infection prevention practices among healthcare personnel (HCP) in a long-term-care (LTC) setting.

DESIGN

Knowledge, attitudes, and practices (KAP) survey.

SETTING

An LTC facility in St Louis, Missouri.

PARTICIPANTS

All HCP working at the LTC facility were eligible to participate, regardless of department or position. Of 170 full- and part-time HCP working at the facility, 73 completed the survey, a 42.9% response rate.

RESULTS

Most HCP agreed that respiratory viral infections were serious and that hand hygiene and face mask use were protective. However, only 46% could describe the correct transmission-based precautions for an influenza patient. Correctly answering infection prevention knowledge questions did not vary by years of experience but did vary for HCP with more direct patient contact versus less patient contact. Furthermore, 42% of respondents reported working while sick, and 56% reported that their coworkers did. In addition, 54% reported that facility policies made staying home while ill difficult. Some respondents expressed concerns about the safety (22%) and effectiveness (27%) of the influenza vaccine, and 28% of respondents stated that they would not get the influenza vaccine if it was not required.

CONCLUSIONS

This survey of staff in an LTC facility identified several areas for policy improvement, particularly sick leave, as well as potential targets for interventions to improve infection prevention knowledge and to address HCP concerns about influenza vaccination to improve HCP vaccination rates in LTCs.

Seasonal influenza vaccination of healthcare workers: systematic review of qualitative evidence

Background

Most countries recommend that healthcare workers (HCWs) are vaccinated seasonally against influenza in order to protect themselves and patients. However, in many cases coverage remains low. A range of strategies have been implemented to increase uptake. Qualitative evidence can help in understanding the context of interventions, including why interventions may fail to achieve the desired effect. This study aimed to synthesise evidence on HCWs’ perceptions and experiences of vaccination for seasonal influenza.

Methods

Systematic review of qualitative evidence. We searched MEDLINE, EMBASE and CINAHL and included English-language studies which reported substantive qualitative data on the vaccination of HCWs for seasonal influenza. Findings were synthesised thematically.

Results

Twenty-five studies were included in the review. HCWs may be motivated to accept vaccination to protect themselves and their patients against infection. However, a range of beliefs may act as barriers to vaccine uptake, including concerns about side-effects, scepticism about vaccine effectiveness, and the belief that influenza is not a serious illness. HCWs value their autonomy and professional responsibility in making decisions about vaccination. The implementation of interventions to promote vaccination uptake may face barriers both from HCWs’ personal beliefs and from the relationships between management and employees within the targeted organisations.

Conclusions

HCWs’ vaccination behaviour needs to be understood in the context of HCWs’ relationships with each other, with management and with patients. Interventions to promote vaccination should take into account both the individual beliefs of targeted HCWs and the organisational context within which they are implemented.

[The seasonal flu vaccination among caregivers in geriatric units: Up-to-date]

BACKGROUND

Flu vaccinations for healthcare professionals seems to be one of the most effective preventive actions in the face of a disease that carries a high risk of a potentially serious nosocomial epidemic in a geriatric environment. The aim of this study was to take stock of the flu vaccination status among caregivers in the geriatric units and to understand the reasons for their reluctance to be vaccinated, in order to put forward proposals to improve vaccination coverage.

METHOD

A literature search of articles published since 2000 in the area of geriatrics, infectious diseases or pneumology was mainly conducted on PubMed using the keywords "caregivers", "elderly", "flu", "influenza", "nosocomial" and "vaccination". After reading all abstracts in English or French and ruling out irrelevant articles, only 64 relevant articles have been listed in bibliography section.

RESULTS

Despite official recommendations, the literature reveals insufficient vaccination coverage of healthcare personnel at both the national and international level. Vaccination coverage seems to be lower among younger female non-medical staff. The factors that determine the likelihood of vaccination are the wish to protect one's self, one's family and patients/residents, as well as the experience of earlier bouts of flu. Factors that oppose vaccination are complex and related to the fear of side effects, the use of other preventive measures, the feeling that vaccination is ineffective, poor understanding of the disease and the vaccine, forgetfulness and problems of organization. Campaigns to promote vaccination that target healthcare professionals must be multidimensional and very incentive. The pedagogical message must be centered on the benefits to the individual and adjusted to socio-professional categories. Mobile strategies in the different departments to encourage staff are a pragmatic solution to this challenge. The referring doctor has an essential role to play, as does the occupational doctor in association with the hospital hygiene services.

CONCLUSION

Flu vaccinations must be included in the education and training of caregivers.

Influenza Vaccination of Healthcare Workers and Vaccine Allocation for Healthcare Workers During Vaccine Shortages

Influenza causes substantial morbidity and mortality annually, particularly in high-risk groups such as the elderly, young children, immunosuppressed individuals, and individuals with chronic illnesses. Healthcare-associated transmission of influenza contributes to this burden but is often under-recognized except in the setting of large outbreaks. The Centers for Disease Control and Prevention has recommended annual influenza vaccination for healthcare workers (HCWs) with direct patient contact since 1984 and for all HCWs since 1993. The rationale for these recommendations is to reduce the chance that HCWs serve as vectors for healthcare-associated influenza due to their close contact with high-risk patients and to enhance both HCW and patient safety. Despite these recommendations as well as the effectiveness of interventions designed to increase HCW vaccination rates, the percentage of HCWs vaccinated annually remains unacceptably low. Ironically, at the same time that campaigns have sought to increase HCW vaccination rates, vaccine shortages, such as the shortage during the 2004-2005 influenza season, present challenges regarding allocation of available vaccine supplies to both patients and HCWs. This two-part document outlines the position of the Society for Healthcare Epidemiology of America on influenza vaccination for HCWs and provides guidance for the allocation of influenza vaccine to HCWs during a vaccine shortage based on influenza transmission routes and the essential need for a practical and adaptive strategy for allocation. These recommendations apply to all types of healthcare facilities, including acute care hospitals, long-term-care facilities, and ambulatory care settings.

Factors Associated with Healthcare Worker Acceptance of Vaccination: A Systematic Review and Meta-analysis

Background and objective.

Healthcare workers experience occupational risk of infection and may transmit infections to patients. Vaccination provides an efficient means of protecting workers and patients, but uptake may be low. We sought to identify factors influencing vaccine acceptance by healthcare workers in order to obtain insights leading to more effective vaccination programs in this population.

Design.

Systematic review and meta-analysis.

Methods.

We searched Medline, Embase, and CINAHL databases to identify studies published up to May 2012. Factors influencing vaccination acceptance were devised a priori. Random-effects meta-analysis was performed to generate summary estimates of effect. Heterogeneity and publication bias were explored using statistical tools.

Results.

Thirty-seven studies evaluating a variety of vaccines (against influenza, pertussis, smallpox, anthrax, and hepatitis B) were included. Homogeneous effects on vaccine acceptance were identified with desire for self-protection (odds ratio [OR], 3.42 [95% confidence interval (CI), 2.42–4.82]) and desire to protect family and friends (OR, 3.28 [95% CI, 1.10–9.75]). Concern that vaccine transmits the illness it was meant to prevent decreased acceptance (OR, 0.42 [95% CI, 0.30–0.58]). Differences in physician and nurse acceptance of immunization were seen between Asian and non-Asian studies.

Conclusions.

Consideration of self-protection (rather than absolute disease risk or protection of patients) appears the strongest and most consistent driver of healthcare workers’ decisions to accept vaccination, though other factors may also be impactful, and reasons for between-study divergence in effects is an important area for future research. This finding has important implications for the design of programs to enhance healthcare worker vaccine uptake.

The challenge of vaccinating adults: attitudes and beliefs of the Canadian public and healthcare providers

OBJECTIVES

Vaccine coverage for recommended vaccines is low among adults. The objective of this study was to assess the knowledge, attitudes, beliefs and behaviours of adults and healthcare providers related to four vaccine-preventable diseases and vaccines (diphtheria-tetanus-pertussis, zoster, pneumococcus and influenza).

DESIGN

We undertook a survey and focus groups of Canadian adults and healthcare providers (doctors, nurses, pharmacists). A total of 4023 adults completed the survey and 62 participated in the focus groups; 1167 providers completed the survey and 45 participated in the focus groups.

RESULTS

Only 46.3% of adults thought they were up-to-date on their vaccines; 30% did not know. In contrast, 75.6% of providers reported being up-to-date. Only 57.5% of adults thought it was important to receive all recommended vaccines (compared to 87.1-91.5% of providers). Positive attitudes towards vaccines paralleled concern about the burden of illness and confidence in the vaccines, with providers being more aware of disease burden and confident in vaccine effectiveness than the public. Between 55.0% and 59.7% of adults reported willingness to be vaccinated if recommended by their healthcare provider. However, such recommendations were variable; while 77.4% of the public reported being offered and 52.8% reported being recommended the influenza vaccine by their provider, only 10.8% were offered and 5.6% recommended pertussis vaccine. Barriers and facilitators to improved vaccine coverage in adults, such as trust-mistrust of health authorities, pharmaceutical companies and national recommendations, autonomy versus the public good and logistical issues (such as insufficient time and lack of vaccination status tracking), were identified by both the public and providers.

CONCLUSIONS

Despite guidelines for adult vaccination, there are substantial gaps in knowledge and attitudes and beliefs among both the public and healthcare providers that lead to low vaccine coverage. A systematic approach that involves education, elimination of barriers and establishing and improving infrastructure for adult immunisation is required.

Influenza vaccination rates and beliefs about vaccination among nursing home employees

BACKGROUND

Recent studies have suggested that vaccination of nursing home staff members may reduce the incidence of influenza among nursing home residents. Current national estimates of employee vaccination rates (around 50%) indicate that residents may be at an unnecessarily high risk of contracting influenza. This article reports on the influenza vaccination rates and attitudes toward the vaccine among employees in 37 nursing homes in 3 states.

METHODS

Nursing home employees were surveyed at nursing homes in Florida, Georgia, and Wisconsin in 2011-2012. Completed surveys were received from a total of 1,965 employees.

RESULTS

Approximately 54% of the employees surveyed received the vaccination during the 2010-2011 and 2011-2012 influenza seasons. Nursing home-level staff vaccination rates varied widely, from 15%-97%. Black and younger employees were less likely to receive the vaccine. Employee vaccination rates in nursing homes that used incentives were 12 percentage points higher than those that did not use incentives (P = .08).

CONCLUSION

Low vaccination rates among nursing home workers may put residents at increased risk for influenza-related morbidity and mortality. The Centers for Medicare and Medicaid Services may consider employee vaccination rates as a quality indicator in addition to resident vaccination rates. Our findings support the use of a trial to test the use of incentives to increase employee vaccination rates.

Healthcare Workers' Knowledge and Attitudes About Pertussis and Pertussis Vaccination

Objective.

To determine knowledge and attitudes about pertussis and pertussis vaccination among healthcare workers (HCWs).

Design.

Self-administered, Web-based survey.

Setting.

Tertiary-care academic medical center.

Participants.

Medical center employees who participated in direct patient care were recruited to complete the survey through institutional e-mail.

Results.

Of 14,893 potentially eligible employees, 1,819 (12%) completed the survey. Most respondents (87%) did not plan to receive the pertussis vaccine. Intent to receive vaccination (which included recent history of vaccination) was associated with the following 4 factors: receipt of a physician recommendation for vaccination (odds ratio [OR], 9.01), awareness of Centers for Disease Control and Prevention recommendations for pertussis vaccination for HCWs (OR, 6.89), receipt of encouragement to be vaccinated from a coworker (OR, 4.72), the belief that HCWs may spread pertussis to patients and family (OR, 1.80). Two factors were negatively associated with intent to receive vaccination: the presence of children in the HCW's home (OR, 0.69) and employment as a nurse (OR, 0.59). Reasons cited by those who did not intend to receive vaccination included lack of a personal recommendation for vaccination (78%), receipt of vaccination as a child (51%), and perception that there was no significant risk for contracting pertussis (38%).

Conclusions.

Of the HCWs surveyed, only 13% intended to receive the pertussis vaccine. A perceived lack of recommendation for vaccination and inaccurate conceptions about pertussis and pertussis vaccination were cited as reasons HCWs did not intend to be vaccinated. Institutional pertussis vaccination campaigns should focus on the risks of healthcare-associated pertussis and new recommendations for pertussis vaccination.

Attitudes and Practices Regarding Influenza Vaccination Among Healthcare Workers Providing Services to Individuals With Spinal Cord Injuries and Disorders

Objective:

To examine influenza vaccination status and predictors for vaccine receipt among healthcare workers (HCWs) caring for patients with spinal cord injuries and disorders.

Design:

Cross-sectional, nationwide anonymous survey.

Setting:

Twenty-three Veterans Affairs spinal cord injury centers.

Participants:

One thousand five hundred fifty-six HCWs.

Methods:

The primary outcome was staff vaccination status. Independent variables included staff demographic and employment characteristics, health status, attitudes and beliefs about the vaccine, and implications for its use.

Results:

The staff vaccination rate was 51%. Leading motivators of vaccine receipt were self-protection (77%) and patient protection (49%). The most common reasons for nonreceipt were concerns about side effects (49%), preventive quality (20%), and inconvenience (14%). Logistic regression results suggested that age of 50 years or older (OR, 1.47; P = .021), male gender (OR, 2.50; P < .001), strong belief in vaccine effectiveness (OR, 19.03; P = .008), and importance of HCW vaccination (OR, 20.50; P = .005) significantly increased the probability of vaccination. Recommending the vaccine to coworkers, patients, or patients' families was also associated with HCW vaccination (OR, 3.20; P < .001). Providers who did not believe the vaccine was protective (P < .001) or effective P < .001) were less likely to recommend it to patients.

Conclusions:

Strategies to increase vaccination rates among HCWs should address concerns about side effects, effectiveness, and protective value of the vaccine and access to it. The impact of provider recommendations should be stressed. Vaccination and subsequent prevention of illness may limit morbidity and mortality, thus benefiting HCWs, healthcare facilities, and patients.

Influenza Vaccination Among Registered Nurses: Information Receipt, Knowledge, and Decision-Making at an Institution With a Multifaceted Educational Program

Objective.

To evaluate the receipt of information and knowledge about influenza and vaccination, as well as influenza vaccination status and reasons for declining vaccination, among registered nurses.

Design.

Cross-sectional survey of registered nurses (RNs).

Setting.

A large tertiary medical center with a long-standing, multifaceted influenza vaccination program and relatively high vaccination rates among employees overall (76.5%).

Participants.

Randomly selected group of 990 RNs employed as inpatient staff nurses at the institution.

Results.

The survey was completed by 513 (51.8%) of 990 RNs. Most RNs (86.7%) had received an influenza vaccination in the past, and 331 (64.5%) intended to receive vaccination during the 2005-2006 influenza season. More than 90% of RNs acknowledged exposure to educational bulletins, and most had received information about influenza severity (383 [74.7%]), transmission (398 [77.6%]), vaccine safety (416 [81.1%]), and the time and location of free vaccination (460 [89.7%]). A majority (436 [85.0%]) felt they had received all the information they needed to make good decisions about vaccination. However, only 49 RNs (9.6%) gave correct answers to more than 85% of the knowledge questions on the survey. The reasons most frequently reported for declining vaccination were doubts about the risk of influenza and the need for vaccination, concerns about vaccine effectiveness and side effects, and dislike of injections.

Conclusions.

RNs exposed to a longstanding, multifaceted educational program had received information about influenza vaccination, but misconceptions were common and only 331 (64.5%) intended to receive vaccination. Strategies other than educational interventions are needed to increase influenza vaccination rates and thereby to ensure healthcare worker and patient safety.

Hepatitis B vaccination coverage among health-care personnel in the United States

OBJECTIVES

We compared self-reported hepatitis B (HepB) vaccine coverage among health-care personnel (HCP) with HepB vaccine coverage among the general population and determined trends in vaccination coverage among HCP.

METHODS

We used the 2010 National Health Interview Survey (NHIS) to determine the weighted proportion of self-reported ≥ 1- and ≥ 3-dose HepB vaccine coverage among HCP aged ≥ 18 years. We used logistic regression to determine independent predictors of vaccination and performed a trend analysis to determine changes in coverage from 2004 to 2010 using data from the 2004-2010 NHIS.

RESULTS

Overall, 69.5% (95% confidence interval [CI] 67.2, 71.8) and 63.4% (95% CI 60.8, 65.9) of HCP reported receiving ≥ 1 and ≥ 3 doses of HepB vaccine, respectively, compared with 27.1% (95% CI 26.1, 28.1%) and 23.0% (95% CI 22.1, 24.0) among non-HCP. Among HCP with direct patient contact, 80.7% (95% CI 78.2, 83.1) and 74.0% (95% CI 71.2, 76.8) received ≥ 1 and ≥ 3 HepB vaccine doses, respectively. Independent predictors of vaccination included direct patient contact, having more than a high school education, influenza vaccination in the past year, and ever having been tested for HIV. There was no significant change in reported coverage from 2004 through 2010.

CONCLUSION

The 2010 HepB vaccine coverage estimate among HCP remained well below the Healthy People 2010 goal of 90%. Efforts to target unvaccinated HCP for preexposure HepB protection should be encouraged.

Knowledge, attitude, and practices about the seasonal influenza vaccination among healthcare workers in Srinagar, India

Please cite this paper as: Bali NK et al. (2012) Knowledge, attitude, and practices about the seasonal influenza vaccination among healthcare workers in Srinagar, India. Influenza and Other Respiratory Viruses 7(4), 540–545.

Background  Healthcare workers (HCWs) universally have a poor uptake of influenza vaccination. However, no data are available from India.

Objective  To explore knowledge, attitudes, and practices associated with influenza vaccination in HCWs in a temperate climate area in northern India.

Patients and Methods  A self‐administered questionnaire was offered to all HCWs in three major hospitals of Srinagar and information sought on motivations, perceptions, preferences and practices regarding influenza vaccination.

Results  Of the 1750 questionnaires received, 1421 (81%) were returned. Only 62 (4·4%) HCWs had ever received influenza vaccination even as 1348 (95%) believed that influenza poses adverse potential consequences for themselves or their contacts; 1144 (81%) were aware of a vaccine against influenza and 830 (58%) of its local availability. Reasons cited by 1359 participants for not being vaccinated included ignorance about vaccine availability (435; 32%), skepticism about efficacy (248; 18%), busy schedule (166; 12%), fear of side effects (70; 4%), and a perception of not being‐at‐risk (82; 6%). Sixty‐one percent (865) believed that vaccine programs are motivated by profit. Eighty‐eight percent opined for mandatory vaccination for HCWs caring for the high‐risk patients, as a part of ‘employee health program’. Most of the participants intended to get vaccinated in the current year even as 684 (48%) held that vaccines could cause unknown illness and 444 (31%) believed their adverse effects to be underreported.

Conclusion  Influenza vaccination coverage among HCWs is dismally low in Srinagar; poor knowledge of vaccine availability and misperceptions about vaccine effectiveness, fear of adverse effects and obliviousness to being‐at‐risk being important barriers. Multifaceted, adaptable measures need to be invoked urgently to increase the coverage.

Vaccine-critical videos on YouTube and their impact on medical students' attitudes about seasonal influenza immunization: a pre and post study

YouTube is a video-sharing platform that is increasingly utilized to share and disseminate health-related information about immunization. Using a pre-post survey methodology, we compared the impact of two of the most popular YouTube videos discussing seasonal influenza vaccine, both vaccine-critical, on the attitudes towards immunizing of first year medical students attending a Canadian medical school. Forty-one medical students were randomized to view either a scientifically styled, seemingly "evidence-based", vaccine-critical video or a video using anecdotal stories of harms and highly sensationalized imagery. In the pre-intervention survey, medical students frequently used YouTube for all-purposes, while 42% used YouTube for health-related purposes and 12% used YouTube to search for health information. While medical students were generally supportive of immunizing, there was suboptimal uptake of annual influenza vaccine reported, and a subset of our study population expressed vaccine-critical attitudes and behaviors with respect to seasonal influenza. Overall there was no significant difference in pre to post attitudes towards influenza immunization nor were there any differences when comparing the two different vaccine-critical videos. The results of our study are reassuring in that they suggest that medical students are relatively resistant to the predominately inaccurate, vaccine-critical messaging on YouTube, even when the message is framed as scientific reasoning. Further empirical work is required to test the popular notion that information disseminated through social media platforms influences health-related attitudes and behaviors. However, our study suggests that there is an opportunity for public health to leverage YouTube to communicate accurate and credible information regarding influenza to medical students and others.

Seeking and processing influenza vaccine information: a study of health care workers at a large urban hospital

In response to low influenza vaccination rates among health care workers, health officials have explored determinants of uptake and developed communication interventions. Key to these efforts is how workers seek and attend to vaccine information. We applied a model of risk information seeking and processing to survey 226 physicians and nurses at a large, urban hospital (response rate = 5.7%; cooperation rate = 91.5%). Our goals were to (1) apply the model to a new setting, audience, and issue and (2) explore novel concepts (e.g., source credibility and information usefulness) and moderating relationships among variables. Consistent with previous research, information subjective norms-perceived social pressure to remain informed about vaccination-were a strong predictor of information seeking and systematic processing. Neither source credibility nor information usefulness independently increased explained variance, although they moderated the relationship between norms and communication behavior. We discuss theoretical and practical implications of these findings.

Predictors of acceptance of H1N1 influenza vaccination by FDNY firefighters and EMS workers

BACKGROUND

There is a widely recognized need for vaccination of health care workers (HCWs). We undertook this study to assess the 2009-2010 H1N1 vaccination rates in ∼14,000 firefighters and emergency medical service (EMS) workers at the Fire Department of New York (FDNY) and to determine predictors of H1N1 vaccine acceptance.

METHODS

After 9/11/01, FDNY developed a bio-preparedness drill where units are dispatched to FDNY-BIOPOD (biologic points of distributions) for rapid distribution of medications/vaccines in the event of a biological disaster. Since 2005, FDNY offers free, voluntary seasonal influenza vaccination during routine medical monitoring/treatment examinations and at FDNY-BIOPOD. In 2009, FDNY-BIOPOD instead offered the H1N1 vaccine. We report on FDNY H1N1 vaccination rates and on predictors of acceptance using bivariate and multivariable techniques.

RESULTS

Overall, 10,612 (77%) FDNY workers were offered H1N1 vaccination, of whom 5831 (55%) accepted. Acceptance was 57.2% during FDNY-BIOPOD compared with 34.4% during medical monitoring/treatment exams (p=0.0001). Workers who accepted prior seasonal influenza vaccinations were 4 times more likely to accept H1N1 vaccination (AOR=4.4, CI(95)=4.0-4.8).

CONCLUSION

FDNY offered H1N1 vaccination to 77% of its workforce during the 2009-2010 season. Prior seasonal vaccine acceptance and vaccination in a group setting such as FDNY-BIOPOD dramatically increased acceptance of the H1N1 vaccine. However, within a voluntary program, additional strategies are needed to further increase vaccine acceptance in first responders and other HCWs.

Predicting seasonal influenza vaccination among hospital-based nurses

A descriptive cross-sectional online survey of a convenience sample of 202 hospital-based nurses was conducted to explore the factors associated with influenza vaccination. The findings suggest that the independent predictors of influenza vaccination were perception of job as a risk increasing factor (OR = 12.14; 95% CI [1.89, 78.08]), workplace vaccination clinics and campaigns (OR = 2.88; 95% CI [1.12, 7.38]), vaccination in the previous season (OR = 34.80; 95% CI [12.99, 93.28]), viewing vaccination as an inconvenience (OR = 0.22; 95% CI [0.07, 0.67]), and one's belief that the immune system provides better protection than the vaccine (OR = 0.29; 95% CI [0.11, 0.77]). In conclusion, the findings support the existing literature with regards to low vaccination rates among health care providers. Furthermore, the identification of the predictors of influenza vaccination among nurses may assist administrators and policy makers with the implementation of evidence-based vaccination strategies.

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.

Determinants of influenza vaccination among healthcare workers

OBJECTIVE

To identify the determinants of influenza vaccination and the moderators of the intention-behavior relationship among healthcare workers (HCWs).

DESIGN

Prospective survey with 2-month follow-up.

SETTING

Three university-affiliated public hospitals.

PARTICIPANTS

Random sample of 424 HCWs.

METHODS

The intention of an HCW to get vaccinated against influenza was measured by means of a self-administered questionnaire based on an extended version of the theory of planned behavior. An objective measure of behavior was extracted 2 months later from the vaccination database of the hospitals.

RESULTS

Controlling for past behavior, we found that the determinants of influenza vaccination were intention (odds ratio [OR], 8.32 [95% confidence interval {CI}, 2.82-24.50]), moral norm (OR, 3.01 [95% CI, 1.17-7.76]), anticipated regret (OR, 2.33 [95% CI, 1.23-4.41]), and work status (ie, full time vs part time; OR, 1.99 [95% CI, 1.92-3.29]). Moral norm also interacted with intention as a significant moderator of the intention-behavior relationship (OR, 0.09 [95% CI, 0.03-0.30]). Again, apart from the influence of past behavior, intention to get vaccinated was predicted by use of the following variables: attitude (beta=.32; P<.001), professional norm (beta=.18; P<.001), moral norm (beta=.18; P<.001), subjective norm (beta=.09; P<.001), and self-efficacy (beta=.08; P<.001). This latter model explained 89% of the variance in HCWs' intentions to get vaccinated against influenza during the next vaccination campaign.

CONCLUSIONS

Our study suggests that influenza vaccination among HCWs is mainly a motivational issue. In this regard, it can be suggested to reinforce the idea that getting vaccinated can reduce worry and protect family members.

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.

Influenza vaccine uptake among staff in care homes in Nottinghamshire: a random cluster sample survey

OBJECTIVES

To establish uptake of influenza vaccine amongst care home clinical staff in Greater Nottingham, and to investigate what could be done to improve vaccine uptake in this group.

STUDY DESIGN

Postal questionnaire surveys were used. In the first instance, a total sample survey was used. In the second instance, a sample of care home staff was surveyed, randomized at the care home level.

METHODS

A postal questionnaire completed by care home matrons was used to obtain a preliminary estimate of staff vaccine uptake. Individual staff questionnaires were then used to validate this finding, and measure attitudes, beliefs and behaviours associated with vaccination.

RESULTS

Vaccine uptake among those working in care homes with nursing was found to be low. Vaccine uptake was higher in homes with a policy recommending vaccination of staff. Most respondents who had received vaccination reported that they had done so because of an existing medical condition, rather than because of being a healthcare worker. A statistically significant relationship (P=0.02) was found between individuals' reported beliefs on how well they could resist influenza and their vaccination status.

CONCLUSIONS

All care homes for the elderly should have a vaccination policy which recommends staff vaccination. Educational campaigns, vaccination in the workplace and free provision of the influenza vaccine may help to improve vaccine uptake in this group.

Influenza vaccination for healthcare workers: from a simple concept to a resistant issue?

Different strategies for the management of influenza epidemics are particularly important in elderly population. High morbidity and mortality rates are associated with influenza in the elderly, and annual vaccination against flu is considered to be the best cost-effective strategy. However, its efficiency is reduced in older adults and only half of them are protected. Several studies show that vaccinating healthcare workers is an efficient way of decreasing mortality rates in nursing home residents within influenza season. National and international public health authorities recommend therefore healthcare worker vaccinations for up to 5 years. However, influenza healthcare worker vaccination coverages are still low. Here we summarize data regarding the justification of healthcare worker vaccination, the efficiency of this strategy, the reasons of the reluctance of vaccination, the means and results of interventional programs and, then, focus on the debate of a mandatory healthcare worker influenza vaccination. Because several interventional programs are efficient but still need high financial and human support, only a strong political-will can improve this chosen strategy.

[Analysis of motivations for antiflu vaccination of the Clermont-Ferrand University Hospital staff]

OBJECTIVE

The vaccination of hospital staff decreases patient mortality and disorganization of services due to sick leave. The main aim of our study was to determine the Clermont-Ferrand University hospital (CHU) personnel's motivations for or against antiflu vaccination to increase the effectiveness of prevention campaigns.

DESIGN

An autoquestionnaire with multiple choices was given to the 7601 CHU staff in May 2005. It documented socioprofessional characteristics, vaccinal status, and reasons for vaccination, nonvaccination, or stopping antiflu vaccination.

RESULTS

The answer rate was 26.5% (2011 autoquestionnaires returned) and representative of the CHU staff. The rate of vaccination in 2004 was 36.35% with a strong correlation between vaccination and former influenza infection (p<0.001). Five of the six principal reasons for vaccination were altruistic including the first two: avoiding transmission to patients (61.8%) and his family (59.8%). The main reason for stopping was the lack of time. The reasons for nonvaccination were linked to a feeling of invulnerability: conviction of not being at risk, of being too young, or in good health.

CONCLUSIONS

The Haute Autorité de santé's objective of vaccinal coverage against influenza for 75% of the health professionals requires their active compliance. The effectiveness of future campaigns could aim at improving knowledge by insisting particularly on the young age of the risk populations. The lack of time can be compensated by offering on-site vaccination, including at night and by proposing larger schedules for vaccination.

Influenza vaccination and decisional conflict among regulated and unregulated direct nursing care providers in long-term-care homes

The purpose of this study was to determine whether direct nursing care providers have decisional conflict about receiving influenza vaccinations and characteristics associated with decisional conflict. The researchers used a self-administered questionnaire mailed to direct nursing care providers in two long-term-care organizations. Most direct nursing care providers in both organizations (80% and 93%, respectively) intended to get the influenza vaccine. Unregulated direct nursing care providers had more decisional conflict than regulated providers, especially related to feeling uninformed about the pros and cons of influenza vaccination. Unclear valuing of the pros and cons of influenza vaccination was related to the age of the direct care providers in both organizations. Decisional conflict and influenza vaccination practices may be determined, in part, by age and by the culture of a health care organization. A decision aid to improve knowledge and clarify values may improve decision quality and increase influenza vaccination rates.

Attitude of Dutch hospital personnel towards influenza vaccination

In 2007, the Dutch Health Council recommended influenza vaccination of all institutional healthcare workers (HCWs). In this questionnaire study largely based on the health belief model we assessed the attitude and intentions of hospital personnel towards such vaccination. We sent out 220 questionnaires to medical personnel and nurses of departments of the University Medical Center Utrecht, The Netherlands. Only one-third of the 112 responders (response rate of 51%) reported a positive intention to comply with the national recommendation. Factors associated with a positive intention were the awareness of a HCW's responsibility not to harm patients, the belief to have a high risk of influenza infection and confidence in vaccine efficacy. Physicians were more likely than nurses and other staff to have a positive intention. Education is needed to convince hospital personnel about influenza vaccination.

High Coverage of Influenza Vaccination Among Healthcare Workers Can Be Achieved During Heightened Awareness of Impending Threat

Introduction: As preparation against a possible avian flu pandemic, international and local health authorities have recommended seasonal influenza vaccination for all healthcare workers at geographical risk. This strategy not only reduces “background noise”, but also chance of genetic shifts in avian influenza viruses when co-infection occurs. We evaluate the response of healthcare workers, stratified by professional groups, to a non-compulsory annual vaccination call, and make international comparisons with countries not at geographical risk. Materials and Methods: A cross-sectional study was performed over the window period for vaccination for the 2004 to 2005 influenza season (northern hemisphere winter). The study population included all adult healthcare workers (aged ≤21 years) employed by a large acute care tertiary hospital. Results: The uptake rates among frontline caregivers – doctors >50%, nurses >65% and ancillary staff >70% – markedly exceeded many of our international counterparts’ results. Conclusion: Given its close proximity in time and space to the avian flu pandemic threat, Singapore healthcare workers responded seriously and positively to calls for preventive measures. Other factors, such as the removal of financial, physical and mental barriers, may have played important facilitative roles as well. Key words: Avian, Flu, Pandemic, Season

Attitudes and knowledge regarding influenza vaccination among hospital health workers caring for women and children

This cross-sectional study of 340 obstetrics/gynecology, 123 neonatology, and 244 pediatric health care workers (HCWs) was designed to evaluate compliance with recommendations concerning the use of influenza vaccine during pregnancy and among pediatric subjects. The results clearly show that only a marginal number of the HCWs in all three fields currently recommend vaccine use for pregnant women and healthy young children. Moreover, all of the HCWs were seriously deficient in terms of their general knowledge of influenza prevention and their own personal vaccination coverage was low. Extensive and sustained efforts to overcome cultural limitations concerning influenza and its prevention are urgently required among HCWs caring for women and children in order to ensure effective compliance with the current recommendations.

The effectiveness of vaccine day and educational interventions on influenza vaccine coverage among health care workers at long-term care facilities

OBJECTIVES

We examined barriers to influenza vaccination among long-term care facility (LTCF) health care workers in Southern California and developed simple, effective interventions to improve influenza vaccine coverage of these workers.

METHODS

In 2002, health care workers at LTCFs were surveyed regarding their knowledge and attitudes about influenza and the influenza vaccine. Results were used to develop 2 interventions, an educational campaign and Vaccine Day (a well-publicized day for free influenza vaccination of all employees at the worksite). Seventy facilities were recruited to participate in an intervention trial and randomly assigned to 4 study groups.

RESULTS

The combination of Vaccine Day and an educational campaign was most effective in increasing vaccine coverage (53% coverage; prevalence ratio [PR]=1.45; 95% confidence interval [CI]=1.24, 1.71, compared with 27% coverage in the control group). Vaccine Day alone was also effective (46% coverage; PR= 1.41; 95% CI=1.17, 1.71). The educational campaign alone was not effective in improving coverage levels (34% coverage; PR=1.18; 95% CI=0.93, 1.50).

CONCLUSION

Influenza vaccine coverage of LTCF health care workers can be improved by providing free vaccinations at the worksite with a well-publicized Vaccine Day.

Influenza vaccine coverage for healthcare workers in geriatric settings in France

BACKGROUND AND AIMS

Because of a relative lack of efficiency of influenza vaccine in the elderly population, influenza outbreaks in geriatric healthcare settings are probable, despite high influenza vaccination rates in patients. Nosocomial influenza outbreaks, more probably related to healthcare workers, have also been reported. Therefore, vaccination of healthcare workers is considered to be an important preventive policy, to decrease the in-hospital influenza burden during the viral circulation period.

METHODS

This multicenter study measured influenza vaccine coverage of Health Care Worker in 102 geriatric healthcare settings (acute care, rehabilitation care, long-term care) by a first questionnaire. A second questionnaire assessed main factors associated with vaccine acceptance.

RESULTS

102 geriatric healthcare settings (20%) answered the first questionnaire. Vaccine coverage for physicians (n=187), nurses (n=631) and nurse assistants (n=1487) were 48.4%, 30.5% and 27.9%, respectively. Vaccination rates were correlated between occupational categories according to healthcare settings. Vaccination rates were significantly lower in acute care settings compared with rehabilitation and long-term care settings. Local recommendations was reported for 29.9%, but was not correlated with vaccine coverage. The second questionnaire showed that lack of motivation and knowledge, and organizational problems were the three main reasons for reluctance to be vaccinated.

CONCLUSIONS

In French geriatric settings, influenza vaccine coverage of healthcare workers is low and highly variable, according to the type of healthcare setting. A group effect was found between occupational categories. However, the reasons for non-acceptance need further evaluation to improve HCW influenza vaccine coverage.

[Influenza vaccination in healthcare workers. Why are some vaccinated whereas others are not]

BACKGROUND AND OBJECTIVE

Influenza vaccination is indicated in health professionals. Nevertheless, vaccination coverage in healthcare workers tends to be low. This paper determines the reasons why some workers are vaccinated whereas others are not and investigates what type of intervention can modify the latter attitude.

METHOD

This was a cross-sectional descriptive study using a questionnaire survey.

SETTING

workers at Hospital General Universitario de Alicante (Alicante, Spain). Absolute frequencies and relative frequencies expressed in percentages were calculated for each of the variables studied. Results were analyzed considering the professional categories of the persons involved and the departments where they worked.

RESULTS

The reasons for influenza vaccination stated by hospital workers were to protect their health (65.6%), the belief that vaccination is beneficial (45.7%), and to avoid transmitting influenza to their patients (42.5%), and to their own families (39.8%). The main reasons for not undergoing vaccination were to avoid medication (17.9%), confidence in their own defenses (17%), or fear of the secondary effects of the vaccine (16.8%).

CONCLUSION

The main reason given by hospital personnel for undergoing vaccination was to protect their own health and that of their family and patients. The reasons most frequently given for not undergoing vaccination were based on possible side effects of the vaccine, the conviction of not being part of a high-risk group, and doubts about the effectiveness of the vaccine as a protective agent. Many of the reasons given for not undergoing vaccination were based on erroneous beliefs and should be taken into account when designing strategies to increase influenza vaccination coverage among health personnel.

Factors that influence influenza vaccination among healthcare workers in a French geriatric hospital

In a geriatric hospital in France, only 80 (21%) of 390 healthcare workers (HCWs) were vaccinated against influenza. Predictive factors for accepting influenza vaccination were occupation as a physician (odds ratio [OR], 9.79), previous receipt of influenza vaccination (OR, 36), and desire to protect their own health (OR, 2.42) and residents' health (OR, 3.68). Predictive factors for refusing influenza vaccination were occupation as a nurse (OR, 6.41) or nursing assistant (OR, 4.04) and belief that homeopathic medication is more effective than the vaccine (OR, 5.75).

Factors that affect influenza vaccine uptake among staff of long-term care facilities

A survey of directors and employees of 36 long-term care facilities in Hesse, Germany, revealed that influenza vaccine uptake among staff was less than 30% in 30 and greater than 50% in 6. The study identified policies and practices associated with vaccination uptake at long-term care facilities and factors associated with the decision of staff to get vaccinated.

Influenza vaccination in German health care workers: effects and findings after two rounds of a nationwide awareness campaign

In Germany, despite longstanding recommendations for influenza vaccination, uptake among health care workers (HCW) is poor. We conducted and evaluated a 2-year nationwide campaign to increase influenza vaccination rates among German HCW. The campaign was tailored to the results of a baseline survey and included the distribution of information material to all German hospitals (n approximately 2000) and engagement of stakeholders, such as professional HCW associations. Human and financial resources consisted of one full-time public health scientist (2 months) and approximately USD 45,000 to produce and distribute materials. We evaluated the intervention in a survey among a systematic sample of HCW in a sample of selected 20 hospitals. HCW were stratified by profession and asked to self-administer a questionnaire inquiring about self-perceived risk for influenza, belief of effectiveness of the vaccine, and influenza vaccination before the starting season (2003/2004) as well as the previous two seasons (2001/2002, 2002/2003). Three hundred and ninety-six of 800 (50%) HCW who were addressed in the evaluated hospitals participated in the evaluation survey. The overall influenza vaccination rate among respondents increased from 21% (2001/2002) to 26% (2003/2004), which was mostly due to a significant increase among physicians (2001/2002: 21%; 2003/2004: 31%; nurses: 20% and 22%, respectively). Significantly more physicians than nurses felt at increased risk for influenza and believed that the vaccine is very effective. Increased uptake among physicians (compared to nurses) was likely due to physicians' higher awareness of their risk and trust in the vaccine. In the future it may be necessary to address nurses differently than physicians. We conclude that a national campaign with very limited resources is feasible and capable of achieving measurable results in a short time frame.
