Trust and the demand for autonomy may explain the low rates of immunizations among nurses

Impact of a COVID-19 certificate requirement on vaccine uptake pattern and intention for future vaccination. A cross-sectional study among French adults

BACKGROUND

In August 2021, France enacted a COVID-19 certificate requirement (vaccination/recovery/test) to access specific services, with mandates for professional groups. We evaluated the impact of this incentive-coercive policy in terms of vaccine uptake equality, future vaccine intention and confidence in authorities' crisis management.

METHODS

In late August 2021, a representative sample of adults (18-75 years) completed an internet-based questionnaire. We classified vaccinated participants by stated reasons for vaccination and estimated adjusted prevalence ratios (aPR) using multivariable Poisson regression. Counterfactual vaccine status assumed non-vaccination of those vaccinated for the certificate. We analysed the association of free-text testimonial themes with level of confidence in authorities.

RESULTS

Among 972 participants, 85.7% were vaccinated or intended vaccination: 3.6% only for certificate/mandate, 17.7% mainly for certificate/mandate plus other reasons, and 64.4% mainly for other reasons. In the counterfactual situation, vaccine uptake would have been significantly more likely among older vs. younger participants (aPR = 1.35) and among those with moderate-high vs. low levels of confidence in authorities for COVID-19 crisis management (aPR = 2.04). In the observed situation, confidence was the only significant determinant of vaccine status (moderate-high vs. low, aPR = 1.39). Among those without genuine motivation for vaccination, professionally active persons were more likely to have ceded to the certificate requirement (aPR = 3.76). Those vaccinated only for the certificate were more likely to express future COVID-19 vaccine intention than unvaccinated persons (aPR = 6.41). Themes significantly associated with lower confidence were criticism of morality (aPR = 1.76) and poor communication by the authorities (aPR = 1.66).

CONCLUSION

The incentive-coercive policy has reduced the negative association of vaccine status with younger age and low confidence in authorities, but may have reinforced isolation of professionally inactive persons. The requirement did not negatively impact future COVID-19 vaccine intention. Future vaccine-incentive policies should pay special attention to populations with low levels of confidence in authorities.

Vaccine hesitancy among health-care professionals in the era of COVID-19

Health-care professionals (HCPs) are key trusted figures in addressing coronavirus disease 2019 (COVID-19) challenges. They are thought to influence others' health decisions by personal example. However, during the COVID-19 crisis, some HCPs hesitated to be vaccinated. We examined factors contributing to that decision. We performed 12 semi-structured interviews, between February and May 2021, with Israeli HCPs who had declined or delayed COVID-19 vaccination. Three coders conducted a combined top-down and bottom-up analysis. We identified four main themes shaping vaccine decision-making: (i) sources of information, (ii) perceptions of necessity and risks of the vaccine, (iii) individual versus collective responsibility and (iv) political climate and media influence. Participants were worried about long-term effectiveness and safety, and while many agreed that high-risk populations should be vaccinated, all considered themselves to be at low risk for serious disease. Some felt they should avoid taking a perceived risk (accepting a new vaccine) to protect society, although they felt pressured to do so. Vaccination campaign politization and the way the media approached the subject also contributed to mistrust and hesitancy to be vaccinated. These findings help us understand HCP beliefs and uncertainties about COVID-19 vaccinations. This study can help inform future campaigns targeted at HCPs to promote the acceptance of vaccines.

College students' sleep difficulty during COVID-19 and correlated stressors: A large-scale cross-sessional survey study

Objective

Sleep difficulty is one of the main concerns during the COVID-19 pandemic. This study examined factors related to vaccination and physical and psychological health conditions, and sleep difficulty in college students in China.

Methods

An online, cross-sectional, anonymous survey was used to investigate college students' perceived sleep difficulty and relevant components (i.e., physical health condition, psychological distress, knowledge of vaccine, and autonomy of vaccine uptake). Hierarchical ordinal logistic regression was conducted to examine the proposed model with the control of participants' demographics (i.e., gender and age).

Results

Valid data of 3,145 students from 43 universities in mainland China was collected in January 2021. The average age of participants was 20.8 years old (S. D. = 2.09). The majority were single (97.4%), and about half were male (49.8%). Results showed that participants had less psychological distress when they had more knowledge about the COVID-19 vaccine and more autonomy to decide whether to receive it. In addition, participants with better physical health experienced less sleep difficulty. In contrast, those with more psychological distress experienced more sleep difficulty.

Conclusions

These findings can inform healthcare providers about the relationship between different factors and difficulty sleeping and aid them in developing interventions addressing sleep difficulties associated with the global pandemic. Health authorities also can improve vaccine uptake and reduce hesitancies in future vaccination campaigns based on the study results showing that greater vaccine knowledge and autonomy reduced psychological distress.

Development and validation of the treatmentself-regulation questionnaire assessing healthcare professionals' motivation for flu vaccination (TSRQ-Flu)

OBJECTIVE

We use self-determination theory to extend the conceptual understanding of flu vaccine hesitancy among health professionals. The scale sheds light on the role played by motivational factors above and beyond traditional cognitive factors such as biased risk judgements and health beliefs.

DESIGN

Across five phases using data from 718 healthcare professionals we establish factor structure, reliability, discriminant, convergent, criterion-related, incremental validity, and measurement invariance of the Treatment Self-Regulation Questionnaire assessing healthcare professionals' motivation for flu vaccination scale (TSRQ-Flu).

MAIN OUTCOME MEASURES

In addition to the four factors of the TSRQ-Flu (autonomous, introjection, external and amotivation regulations), we assess intentions to vaccinate, past vaccination behaviour and validate the scale using measures of cognitive empowerment, vaccine attitudes and social desirability.

RESULTS

Our findings indicate that the newly developed 11-item scale is distinct from and contributes over and beyond other psychosocial measures of flu vaccination intentions and can be used to understand the motivation of both vaccinated and not-vaccinated healthcare professionals.

CONCLUSION

This new scale has the potential to make a marked change in the conceptualisation of the roots of vaccine hesitancy among healthcare professionals and aid healthcare managers in developing evidence-based interventions to promote vaccination among their staff.

"You Have to Die Not to Come to Work": A Mixed Methods Study of Attitudes and Behaviors regarding Presenteeism, Absenteeism and Influenza Vaccination among Healthcare Personnel with Respiratory Illness in Israel, 2016-2019

INTRODUCTION

Healthcare personnel (HCP) have an increased risk of exposure to influenza and other respiratory pathogens. Increased presenteeism, decreased absenteeism, and low uptake of the influenza vaccine can contribute to the spread of influenza among HCP in healthcare settings. We used a mixed methods approach to investigate attitudes and behaviors of HCP in Israel towards influenza vaccination, presenteeism, and absenteeism.

METHODS

The study took place over three influenza seasons (2016-2017, 2017-2018, 2018-2019) at the largest hospital in southern Israel. We administered a Knowledge, Attitudes and Practices (KAP) questionnaire and conducted semi-structured interviews with HCP who had been recently ill with respiratory symptoms. The KAP questionnaire included closed-ended questions about attitudes and behaviors regarding influenza, working while sick, and influenza vaccination. The interviews investigated HCP's perceptions of influenza infection and attitudes about absenteeism, presenteeism, and the influenza vaccine.

RESULTS

We conducted 74 semi-structured interviews over three influenza seasons. Four HCP were interviewed twice, in separate seasons for different illness episodes. The 70 individuals interviewed included 16 physicians, 45 nurses or technicians, and 9 administrative staff. The median age was 42.5 years (range: 25-60), and most (79%) were female. Half (50%) got vaccinated against influenza before their illness episode. In interviews, most HCP said they come to work while sick (presenteeism) due to a strong personal work ethic and an institutional culture that discourages taking sick leave (absenteeism). HCP expressed skepticism about the effectiveness of the influenza vaccine as well as concern that the influenza vaccine causes severe illness.

DISCUSSION

Over three influenza seasons in Israel, HCP cited a number of reasons for working while sick, and doubted the usefulness of influenza vaccine. Addressing reasons for presenteeism and vaccine hesitancy among HCP is crucial to protect HCP and patients from influenza virus infection and other viral respiratory illnesses, such as COVID-19.

Barriers and facilitators to seasonal influenza vaccination uptake among nurses: A mixed methods study

AIM

To identify the barriers and facilitators to seasonal influenza vaccination uptake among nurses.

BACKGROUND

Seasonal influenza causes significant mortality and morbidity among older people and high-risk groups. Vaccinating nurses against influenza is an essential public health measure to reduce the burden of disease. Yet despite annual recommendations, nurses' influenza vaccine uptake rates remain low.

DESIGN

An explanatory sequential mixed methods study design.

DATA SOURCES

Qualified nurses attending mandatory training in two large acute hospitals in Ireland.

METHODS

A paper-based questionnaire assessing nurses' knowledge, risk perception, health beliefs and influenza vaccination practices was distributed to a convenience sample of qualified nurses (N = 462) between September 2017 - February 2018. A self-selected sample of 35 nurses who completed the questionnaire participated in five focus groups to explore in depth the barriers and facilitating factors associated with their vaccination practices between September 2018 - October 2018. The questionnaire data were analysed statistically and thematic analysis was applied to the qualitative data. The quantitative and qualitative findings were integrated using the Pillar Integration Process.

RESULTS

Seven themes emerged: (a) the influence of nurses' knowledge on vaccine uptake; (b) dissemination of information; (c) vaccine fears and concerns; (d) protection, risk and vulnerability: self and others; (e) influencers; (f) accessibility; and (g) organizational pressure.

CONCLUSION

Achieving high vaccine uptake rates among nurses through voluntary vaccination programmes remains a challenge. Multi-faceted influenza campaigns based on the HBM should be prioritized to address dissemination of evidence-based knowledge, accessibility, and external cues to action.

IMPACT

Low influenza vaccine uptake among nurses compromises patient safety and contributes to a significant burden on health services. This study identified factors associated with vaccine practices among nurses and will inform the development of specific tailored interventions for nurses.

A systematic review of adult tetanus-diphtheria-acellular (Tdap) coverage among healthcare workers

During the last decades pertussis incidence raised globally. Several vaccination strategies targeting adults to reduce pertussis among young infants have been proposed, including vaccination of healthcare workers (HCWs). The aim of this study was to analyse, by performing a systematic review of literature, published papers that evaluated Tdap coverage among HCWs, variables associated with vaccine uptake and efforts implemented to raise vaccination rates. We searched the MedLine, Embase, SCOPUS, LILACS, Web of Science and Cochrane for full-text studies that evaluated Tdap coverage in HCW. Two independent reviewers screened the articles and extracted the data.Twenty-eight studies published from 2009 to 2018 were reviewed. Most studies were conducted in the USA. Initial Tdap coverage varied from 6.1% to 63.9%. USA and France are the only two countries with studies evaluating Tdap coverage within HCWs using national data. In the USA, Tdap coverage in HCWs raised from 6.1% to 45.1% from 2007 to 2015. In the analysis of French national data, a Tdap coverage of 63.9% was observed. Five studies used interventions to raise Tdap coverage in HCWs. Two intervention studies implemented mandatory vaccination and three used educational strategies. All of them achieved coverages over 86%. Only eleven studies analysed the association of Tdap vaccination with variables of interest. Previous immunization with other vaccines recommended for HCWs (like influenza, hepatitis B and MMR) was positively associated with Tdap uptake in four studies. In conclusion, overall Tdap coverage among HCWs is low, but seems to increase over the years after the vaccine introduction and with implementation of interventions to increase coverage.

Barriers of Influenza Vaccination Intention and Behavior - A Systematic Review of Influenza Vaccine Hesitancy, 2005 - 2016

BACKGROUND

Influenza vaccine hesitancy is a significant threat to global efforts to reduce the burden of seasonal and pandemic influenza. Potential barriers of influenza vaccination need to be identified to inform interventions to raise awareness, influenza vaccine acceptance and uptake.

OBJECTIVE

This review aims to (1) identify relevant studies and extract individual barriers of seasonal and pandemic influenza vaccination for risk groups and the general public; and (2) map knowledge gaps in understanding influenza vaccine hesitancy to derive directions for further research and inform interventions in this area.

METHODS

Thirteen databases covering the areas of Medicine, Bioscience, Psychology, Sociology and Public Health were searched for peer-reviewed articles published between the years 2005 and 2016. Following the PRISMA approach, 470 articles were selected and analyzed for significant barriers to influenza vaccine uptake or intention. The barriers for different risk groups and flu types were clustered according to a conceptual framework based on the Theory of Planned Behavior and discussed using the 4C model of reasons for non-vaccination.

RESULTS

Most studies were conducted in the American and European region. Health care personnel (HCP) and the general public were the most studied populations, while parental decisions for children at high risk were under-represented. This study also identifies understudied concepts. A lack of confidence, inconvenience, calculation and complacency were identified to different extents as barriers to influenza vaccine uptake in risk groups.

CONCLUSION

Many different psychological, contextual, sociodemographic and physical barriers that are specific to certain risk groups were identified. While most sociodemographic and physical variables may be significantly related to influenza vaccine hesitancy, they cannot be used to explain its emergence or intensity. Psychological determinants were meaningfully related to uptake and should therefore be measured in a valid and comparable way. A compendium of measurements for future use is suggested as supporting information.

Intention to Accept Pertussis Vaccination for Cocooning: A Qualitative Study of the Determinants

Context

Several countries have reported a resurgence of pertussis in the last decades. This puts infants (especially <6 months) at risk of severe complications, because they are too young to be fully protected by vaccination. The global pertussis initiative has proposed pertussis vaccination of young infants’ close contacts, in order to reduce pertussis transmission and the burden of the disease on infants. Our aim is to explore the perceived determinants (barriers and facilitators) of intention to accept vaccination among the possible target groups of pertussis vaccination for cocooning. Consideration of these determinants is necessary to optimise the uptake of the vaccination.

Methods

We conducted 13 focus groups and six individual semi-structured interviews with members of possible target groups for pertussis cocooning (i.e. parents, maternity assistants, midwives, and paediatric nurses) in the Netherlands. Here, both maternal pertussis vaccination as well as pertussis cocooning has not been implemented. The topic list was based on a literature review and a barrier framework. All interviews were transcribed verbatim and two researchers performed thematic content analysis.

Findings

The participants’ risk perception, outcome expectations, general vaccination beliefs, moral norms, opinion of others, perceived autonomy, anticipated regret, decisional uncertainty, and perceived organisational barriers were all factors that influenced the intention to accept pertussis vaccination for cocooning.

Discussion

This study has identified nine perceived determinants that influence the intention to accept pertussis cocooning vaccination. We add the following determinants to the literature: perceived cost-effectiveness (as a concept of outcome expectations), justice (as a concept of moral norms), anticipated regret, and decisional uncertainty. We recommend considering these determinants in vaccination programmes for pertussis cocooning vaccination. Experience, information and trust emerged as predominant themes within these determinants. These themes require particular attention in future research on vaccination acceptance, especially with regard to their role in use and implementation in policy and practice.

Vaccine hesitancy as self-determination: an Israeli perspective

Vaccine hesitancy can be portrayed as a broad spectrum of phenomena, ranging from a genuine call for help to complete defiance of authorities. The emphasis here is made on mid-spectrum hesitancy; hesitancy as an act of personal exploration and deliberation whether to get vaccinated or not. This form of vaccine hesitancy can be identified in the attitude of the Israeli public towards routine childhood vaccination programs, seasonal flu vaccination, newly introduced vaccines, such as human papilloma virus vaccine, as well as towards the emergency vaccination programs against poliovirus and H1N1 pandemic influenza. Vaccine hesitancy in Israel appears to be a process where individuals exercise self-determination and self-empowerment and make their own decisions based on assessment, reflection, choosing between various options and dealing with considerable complexities.

Addressing this form of vaccine hesitancy could be challenging, but ultimately fruitful. This would require change of attitudes on the part of policymakers. The first steps should involve the realization that deliberative hesitancy is here to stay, and that hesitant individuals should be respected. This could pave the way for designing appropriate intervention strategies for convincing the hesitant public about the advantages of vaccination.

Attitudes and perceptions among the pediatric health care providers toward influenza vaccination in Qatar: A cross-sectional study

BACKGROUND

Influenza is a communicable but preventable viral illness. Despite safe and effective vaccine availability, compliance rates are globally low. Neither local data on percentage of vaccination nor reasons for poor compliance among pediatric health providers are available in Qatar.

AIM

To estimate the percentage of vaccinated health care providers at pediatrics department and know their perception and attitudes toward influenza vaccinations.

METHODS

Cross-sectional survey, conducted on 300 pediatrics healthcare professionals from January through April 2013 at the main tertiary teaching hospital in Qatar, included details of demographics, frequency, perceptions and suggestive ways to improve the compliance.

FINDING

From among 230 respondents, 90 physicians and 133 allied health care professionals participated in this survey. Our study showed that percentages of participants who received flu vaccination were 67.7% and those who did not receive vaccination were 32.3%. Allied HCPs (69%) are more likely to get the vaccine compared to the physicians (66%). flu vaccination was approximately 5 times likely to be higher in the age group more than 40 years (P=0.002) compared to age less than or equals 40 years. Overall 70% healthcare providers were willing to recommend immunization to colleagues and patients compared to 30%, who were not willing. The reasons for noncompliance included fear of side effects, contracting the flu, vaccine safety and lack of awareness about the effectiveness. In order to promote immunization, participants believe that use of evidence-based statement, participating in an educational campaign, provides no cost/on site campaigns and leadership support is the most practical interventions.

CONCLUSIONS

In the present study, the vaccine coverage among pediatrics HCPs seems higher than previously reported rates. Despite their positive attitude toward influenza vaccination, low acceptance and misconceptions of seasonal influenza vaccination by pediatric HCPs may have a negative effect on the successful immunization delivery and children immunization rate. Our findings would be useful for designing and implementing educational programs targeted to improve vaccination coverage rates.
