A statewide system for improving influenza vaccination rates in hospital employees

Lack of Informations about COVID-19 Vaccine: From Implications to Intervention for Supporting Public Health Communications in COVID-19 Pandemic

Lack of knowledge and mistrust towards vaccines represent a challenge in achieving the vaccination coverage required for population immunity. The aim of this study is to examine the opinion that specific demographic groups have about COVID-19 vaccination, in order to detect potential fears and reasons for negative attitudes towards vaccination, and to gain knowledge on how to prepare strategies to eliminate possible misinformation that could affect vaccine hesitancy. The data collection approach was based on online questionnaire surveys, divided into three groups of questions that followed the main postulates of the health belief theory—a theory that helps understanding a behaviour of the public in some concrete surrounding in receiving preventive measures. Ordinary least squares regression analyses were used to examine the influence of individual factors on refusing the vaccine, and to provide information on the perception of participants on the danger of COVID-19 infection, and on potential barriers that could retard the vaccine utility. There was an equal proportion of participants (total number 276) who planned on receiving the COVID-19 vaccine (37%), and of those who did not (36.3%). The rest (26.7%) of participants were still indecisive. Our results indicated that attitudes on whether to receive the vaccine, on how serious consequences might be if getting the infection, as well as a suspicious towards the vaccine efficacy and the fear of the vaccine potential side effects, may depend on participants’ age (<40 vs. >40 years) and on whether they are healthcare workers or not. The barriers that make participants‘ unsure about of receiving the vaccine, such as a distrust in the vaccine efficacy and safety, may vary in different socio-demographic groups and depending on which is the point of time in the course of the pandemic development, as well as on the vaccine availability and experience in using certain vaccine formulas. There is a pressing need for health services to continuously provide information to the general population, and to address the root causes of mistrust through improved communication, using a wide range of policies, interventions and technologies.

Web-Based Electronic Health Records Improve Data Completeness and Reduce Medical Discrepancies in Employee Vaccination Programs

A Web-based electronic health record (EHR) system was compared with traditional paper-based documentation and vaccination tracking during the 2009 H1N1 influenza pandemic. In a cohort of 8,411 healthcare network employees, EHRs improved completeness of self-reported contraindication data and reduced medical discrepancies. Vaccination program quality and accuracy are enhanced by EHRs.

Revised SHEA Position Paper: Influenza Vaccination of Healthcare Personnel

Executive Summary

This document serves as an update and companion piece to the 2005 Society for Healthcare Epidemiology of America (SHEA) Position Paper entitled “Influenza Vaccination of Healthcare Workers and Vaccine Allocation for Healthcare Workers During Vaccine Shortages.” In large part, the discussion about the rationale for influenza vaccination of healthcare personnel (HCP), the strategies designed to improve influenza vaccination rates in this population, and the recommendations made in the 2005 paper still stand. This position paper notes new evidence released since publication of the 2005 paper and strengthens SHEA's position on the importance of influenza vaccination of HCP. This document does not discuss vaccine allocation during times of vaccine shortage, because the 2005 SHEA Position Paper still serves as the Society's official statement on that issue.

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

Background.

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

Objective.

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

Design and Setting.

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

Methods.

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

Results.

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

Conclusion.

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

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

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

Reliability and validity of a standardized measure of influenza vaccination coverage among healthcare personnel

OBJECTIVE

To evaluate the reliability and validity of a standardized measure of healthcare personnel (HCP) influenza vaccination.

SETTING

Acute care hospitals, long-term care facilities, ambulatory surgery centers, physician practices, and dialysis centers from 3 US jurisdictions.

PARTICIPANTS

Staff from 96 healthcare facilities randomly sampled from 234 facilities that completed pilot testing to assess the feasibility of the measure.

METHODS

Reliability was assessed by comparing agreement between facility staff and project staff on the classification of HCP numerator (vaccinated at facility, vaccinated elsewhere, contraindicated, declined) and denominator (employees, credentialed nonemployees, other nonemployees) categories. To assess validity, facility staff completed a series of case studies to evaluate how closely classification of HCP groups aligned with the measure's specifications. In a modified Delphi process, experts rated face validity of the proposed measure elements on a Likert-type scale.

RESULTS

Percent agreement was high for HCP vaccinated at the facility (99%) and elsewhere (95%) and was lower for HCP who declined vaccination (64%) or were medically contraindicated (64%). While agreement was high (more than 90%) for all denominator categories, many facilities' staff excluded nonemployees for whom numerator and denominator status was difficult to determine. Validity was lowest for credentialed and other nonemployees.

CONCLUSIONS

The standardized measure of HCP influenza vaccination yields reproducible results for employees vaccinated at the facility and elsewhere. Adhering to true medical contraindications and tracking declinations should improve reliability. Difficulties in establishing denominators and determining vaccination status for credentialed and other nonemployees challenged the measure's validity and prompted revision to include a more limited group of nonemployees.

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSION

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

A public health initiative to increase annual influenza immunization among hospital health care personnel: the San Diego Hospital Influenza Immunization Partnership

BACKGROUND

A public health department-supported intervention to increase influenza immunization among hospital-based health care practitioners (HCPs) in San Diego County took place between 2005 and 2008. The study included all major hospitals in the county, with a population of approximately 3.5 million.

METHODS

Information on hospital activities was collected from before, during and after initiative activities. Vaccination status and demographics were collected directly from HCP using hospital-based and random-dialed telephone surveys.

RESULTS

Between 2006 and 2008, hospitals increased promotion activities and reported increases in vaccination rates. Based on the random-dialed surveys, HCP influenza vaccination coverage rates did not increase significantly. Vaccination rates were significantly higher in HCPs who reported that employers provided free vaccination and those who believed that their employers mandated influenza vaccination.

CONCLUSIONS

This local public health initiative and concurrent state legislation were effective in increasing employer efforts to promote influenza vaccination; however, population-based surveys of HCPs did not show significant increases in influenza vaccination. Overall, this study suggests that public health leadership, intensive employer promotion activities, and state-required declinations alone were not sufficient to significantly increase HCP influenza vaccination. Policymakers and employers should consider mandates to achieve optimal influenza vaccination among HCPs.

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

AIMS AND OBJECTIVES

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

BACKGROUND

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

DESIGN

Instrument development and initial validity and reliability testing.

METHODS

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

RESULTS

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

CONCLUSIONS

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

RELEVANCE TO CLINICAL PRACTICE

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

New approaches for influenza vaccination of healthcare workers

PURPOSE OF REVIEW

Vaccination of healthcare workers (HCWs) against influenza is an important component of infection control in healthcare settings but HCW vaccination rates remain low. Here we review current and emerging strategies for influenza vaccination of HCWs.

RECENT FINDINGS

Professional organizations have recommended annual influenza vaccination for HCWs since 1984, but HCW vaccination rates have improved minimally. Recent studies indicate that comprehensive influenza vaccination programs have failed to achieve adequate influenza vaccination rates for HCWs in spite of allocating substantial resources to HCW vaccination programs. Mandatory HCW influenza vaccination programs have been introduced and clearly outperform traditional comprehensive vaccination programs. Some argue that mandatory vaccination programs infringe on HCW autonomy, and introduction of mandatory vaccination programs can be controversial. Public reporting of institutional HCW influenza vaccination rates is another strategy to achieve high vaccination rates, as HCW influenza vaccination may be used in the future as a quality and safety metric.

SUMMARY

HCW influenza vaccination in the setting of a comprehensive infection control program is a core patient-safety practice. Mandatory HCW influenza vaccination and public reporting of HCW vaccination rates will complement one another in achieving substantial gains for HCW influenza vaccination programs.

A successful, voluntary, multicomponent statewide effort to reduce health care-associated infections

Health care-associated infections (HAIs) increase morbidity, mortality, and hospital costs. Multiple organizations have worked independently to reduce HAIs. Regional collaborative efforts to reduce HAIs have been less common but may be particularly effective. The authors describe a statewide multicomponent approach implemented by the Iowa Healthcare Collaborative (IHC) to reduce HAIs. IHC's initiatives helped providers improve patient care by becoming engaged in specific projects, improving communication, sharing data, and implementing best practices. Other states could use this approach as a model to engage clinicians in patient safety initiatives and thereby accelerate the rate at which clinical care and health care outcomes are improved.
