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

OBJECTIVE: In 2006 a voluntary, provider-based project was initiated to improve influenza vaccination rates among healthcare workers (HCWs) employed by acute care hospitals in Iowa. The statewide vaccination target was 95% by 2010. Data from the first four influenza seasons (2006-2007, 2007-2008, 2008-2009 and 2009-2010) are presented. METHODS: A website was used to submit and circulate hospital-specific influenza vaccination rates. Rates were fed back to participating hospitals from the outset and hospital-specific rates made publicly available for the last two influenza seasons. RESULTS: Hospital participation rates ranged from 86% in season 1 to 100% in the subsequent three seasons. Statewide median hospital employee vaccination rates trended upward from 73% in season 1 to 93% in season 4. By season 4, 35% of participating hospitals had reached or exceeded a 95% vaccination rate. In season 4 the mean employee vaccination rate of 19 hospitals reporting use of a mandatory vaccination policy was 96% vs. 87% in the 64 hospitals not using such policies. CONCLUSION: Over a 4 year period, while participating in a provider-based, voluntary project, acute care hospitals in Iowa reported significantly improved seasonal influenza vaccination rates among their employees.

Implementation of mandatory immunisation of healthcare workers: observations from New South Wales, Australia.

OBJECTIVE: To identify factors influencing implementation of a state-wide mandatory immunisation policy for healthcare workers (HCWs) in New South Wales (NSW), Australia, in 2007. Vaccines included were measles, mumps, rubella, varicella, hepatitis B, diphtheria, tetanus and pertussis, but not influenza. METHODS: We evaluated the first 2 years of this policy directive in 2009. A qualitative study was conducted among 4 stakeholder groups (the central health department, hospitals, health professional associations, and universities). 58 participants were identified using maximum variation sampling and data were analysed using a hierarchical thematic framework. Quantitative data on policy compliance were reviewed at the regional level. RESULTS: Success in policy implementation was associated with effective communication, including support of clinical leaders, provision of free vaccine, access to occupational health services which included immunisation, and appropriate data collection and reporting systems. Achieving high vaccine uptake was more challenging with existing employees and with smaller institutions. CONCLUSION: These findings may apply to other jurisdictions in Australia or internationally considering mandatory approaches to HCW vaccination.

Results of a national survey of infectious diseases specialists regarding influenza vaccination programs for healthcare workers.

A minority of infectious diseases consultants currently work in healthcare institutions requiring influenza vaccination for healthcare workers, and in approximately half of these institutions, the healthcare workers who refuse vaccination do not face substantial consequences for their refusal. Although true mandatory policies are not common, a majority of infectious diseases consultants support such policies.

Making influenza vaccination mandatory for health care workers: the views of NSW Health administrators and clinical leaders.

The challenges of maintaining high influenza vaccination rates in health care workers have focused worldwide attention on mandatory measures. In 2007, NSW Health issued a policy directive requiring health care workers to be screened/vaccinated for certain infectious diseases. Annual influenza vaccine continued to be recommended but not required. This paper describes the views of NSW Health administrators and clinical leaders about adding influenza vaccination to the requirements. Of 55 staff interviewed, 45 provided a direct response. Of these, 23 supported inclusion, 14 did not and eight were undecided. Analysis of interviews indicated that successfully adding influenza vaccination to the current policy directive would require four major issues to be addressed: (1) providing and communicating a solid evidence base supporting the policy directive; (2) addressing the concerns of staff about the vaccine; (3) ensuring staff understand the need to protect patients; and (4) addressing the logistical challenges of enforcing an annual vaccination.

A statewide system for improving influenza vaccination rates in hospital employees.

OBJECTIVE: To describe and report the progress of a provider-initiated approach to increase influenza immunization rates for healthcare workers. DESIGN: Observational study. SETTING: The State of Iowa. SUBJECTS: Acute care hospitals in Iowa. METHODS: Hospitals reported rates of employee influenza vaccination to a provider-based collaborative during 2 influenza seasons (2006-2007 and 2007-2008). Hospital characteristics related to higher vaccination rates were examined. RESULTS: One hundred (87.0%) of 115 Iowa hospitals and/or health systems participated in season 1; individual hospital vaccination rates ranged from 43.5% to 99.2% (mean, 72.4%; median, 73.1%). In season 2, 115 (100%) of 115 Iowa hospitals and/or health systems participated. Individual hospital vaccination rates ranged from 53.6% to 100% (mean, 79.5%; median, 82.0%). In both seasons, urban and large hospitals had vaccination rates that were 6.3% to 7.6% lower than those of hospitals in other locations. Hospitals that used declination statements had influenza vaccination rates 12.6% higher than hospitals that did not use declination statements in season 2. CONCLUSION: The initial vaccination rates were high for healthcare workers in Iowa, especially in smaller rural hospitals, and rates increased during season 2. The successful voluntary approach for reporting influenza vaccination rates that we describe provides an efficient platform for collecting and disseminating other statewide measures of healthcare quality.

Use of a pandemic preparedness drill to increase rates of influenza vaccination among healthcare workers.

OBJECTIVE: To determine the effect of a pandemic influenza preparedness drill on the rate of influenza vaccination among healthcare workers (HCWs). DESIGN: Before-after intervention trial. SETTING: The University of Iowa Hospitals and Clinics (UIHC), a large, academic medical center, during 2005. SUBJECTS: Staff members at UIHC. METHODS: UIHC conducted a pandemic influenza preparedness drill that included a goal of vaccinating a large number of HCWs in 6 days without disrupting patient care. Peer vaccination and mobile vaccination teams were used to vaccinate HCWs, educational tools were distributed to encourage HCWs to be vaccinated, and resources were allocated on the basis of daily vaccination reports. Logit models were used to compare vaccination rates achieved during the 2005 vaccination drill with the vaccination rates achieved during the 2003 vaccination campaign. RESULTS: UIHC vaccinated 54% of HCWs (2,934 of 5,467) who provided direct patient care in 6 days. In 2 additional weeks, this rate increased to 66% (3,625 of 5,467). Overall, 66% of resident physicians (311 of 470) and 63% of nursing staff (1,429 of 2,255) were vaccinated. Vaccination rates in 2005 were significantly higher than the hospitalwide rate of 41% (5,741 of 14,086) in 2003. CONCLUSIONS: UIHC dramatically increased the influenza vaccination rate among HCWs by conducting a pandemic influenza preparedness drill. Additionally, the drill allowed us to conduct a bioemergency drill in a realistic scenario, use innovative methods for vaccine delivery, and secure administrative support for future influenza vaccination campaigns. Our study demonstrates how a drill can be used to improve vaccination rates significantly.

Ensuring preparedness for potential poliomyelitis outbreaks: Recommendations for the US poliovirus vaccine stockpile from the National Vaccine Advisory Committee (NVAC) and the Advisory Committee on Immunization Practices (ACIP).

Paralytic poliomyelitis was once endemic in the United States; however, because of high vaccination levels, the last case of wild disease occurred in 1979. Although worldwide polio eradication may be achieved in the near future, the presence of undervaccinated children in urban areas and among groups who refuse vaccination creates an outbreak risk, should importation of wild virus occur. In 1999, the Advisory Committee on Immunization Practices (ACIP) recommended that inactivated poliovirus vaccine (IPV) be used for routine immunization of the US population and that oral poliovirus vaccine (OPV) be reserved for "mass vaccination campaigns to control outbreaks of paralytic polio." Subsequently, the sole US manufacturer of OPV withdrew from the market. In 2003, a joint National Vaccine Advisory Committee (NVAC)/ACIP working group was charged with reporting to its parent bodies concerning the need for a poliovirus vaccine stockpile. Based on that working group's report, the NVAC and ACIP have concluded that stockpiles of both IPV and OPV should be maintained. In the event of an outbreak in which OPV continues not to be available, IPV should be used for control, and a stockpile of 8 million doses seems to be sufficient. Should IPV be manufactured only in combination with other vaccines, appropriate procurement actions should be taken to ensure that uncombined IPV continues to be stockpiled. Under circumstances of diminished population immunity, OPV may offer outbreak control advantages. The NVAC and ACIP recommend that the United States collaborate with international agencies to provide guaranteed and rapid access to at least 8 million doses of trivalent OPV or 8 million doses of each of the 3 types of monovalent OPV. The regulatory and practical obstacles to implementation of this recommendation will require assertive facilitation at high levels of the federal government and careful planning at the state and local levels.

Strengthening the supply of routinely recommended vaccines in the United States: recommendations from the National Vaccine Advisory Committee.

Between late 2000 and the spring of 2003, the United States experienced shortages of vaccines against 8 of 11 preventable diseases in children. In response, the Department of Health and Human Services requested that the National Vaccine Advisory Committee (NVAC) make recommendations on strengthening the supply of routinely recommended vaccines. The NVAC appointed a Working Group to identify potential causes of vaccine supply shortages, develop strategies to alleviate or prevent shortages, and enlist stakeholders to consider the applicability and feasibility of these strategies. The NVAC concluded that supply disruptions are likely to continue to occur. Strategies to be implemented in the immediate future include expansion of vaccine stockpiles, increased support for regulatory agencies, maintenance and strengthening of liability protections, improved communication among stakeholders, increased availability of public information, and a campaign to emphasize the benefits of vaccination. Strategies requiring further study include evaluation of appropriate financial incentives to manufacturers and streamlining the regulatory process without compromising safety or efficacy.
