To the Editor—Annual vaccination of healthcare personnel (HCP) is a high priority for reducing influenza-associated morbidity in healthcare settings. 1 Although the percentage of HCP nationwide who reported receiving influenza vaccination was 78.6% in the 2016–2017 season, coverage remains incomplete, placing HCP and patients at risk of influenza. 1 , Reference Black, Yue and Ball 2 Employer influenza vaccination requirements are associated with higher coverage rates, and though controversial, mandatory influenza vaccination is supported by multiple healthcare professional societies.Reference Pitts, Maruthur, Millar, Perl and Segal 3 , Reference Maurer, Harris, Black and Euler 4 We explored agreement with employer influenza vaccination requirements among HCP nationwide.

Methods

We used data from the opt-in Internet panel survey of HCP for the 2016–2017 influenza season conducted from March 28 to April 19, 2017. Similar surveys have been conducted using 2 national opt-in Internet sources since the 2010–2011 influenza season to provide estimates of influenza vaccination coverage among HCP.Reference Black, Yue and Ball 2

In addition to questions about influenza vaccination coverage, occupation type, and healthcare setting, the survey included the statement, “Healthcare workers should be required to be vaccinated for flu.” Respondents were asked to rate their agreement with the statement using a 4-point scale. Responses of strongly agree and agree were combined and categorized as expressed agreement. Responses of strongly disagree and disagree were combined and categorized as expressed disagreement.

We weighted responses to the US HCP population by age, sex, race/ethnicity, work setting, and census region based on Bureau of Labor Statistics and US Census Bureau data. We calculated the number and weighted percentage of HCP who expressed agreement or disagreement with the vaccination requirement statement by occupation type, healthcare setting, vaccination status, and employer promotion efforts. Additional statistical analyses were not performed because this survey included an opt-in sample and a nonrandom sample.

Results

Overall, 72.9% of 2,438 respondents expressed agreement with the vaccination requirement statement. In total, 78.6% of respondents reported receiving an influenza vaccination during the 2016–2017 season, and 42.3% of respondents reported working in a setting with employer influenza vaccination requirements.Reference Black, Yue and Ball 2 Table 1 shows the weighted percentage of respondents who expressed agreement with the statement by occupation type, healthcare setting, vaccination status, and employer promotion efforts. By healthcare setting, the weighted percentage of respondents who expressed agreement ranged from 70.9% (ambulatory care settings) to 77.2% (hospitals). By occupation, the weighted percentage of respondents who expressed agreement ranged from 67.4% (other clinical HCP) to 85.7% (physicians).

a Weights were calculated based on each occupation type, by age, sex, race/ethnicity, healthcare setting, and US census region to represent the US HCP population.

b Respondents could choose >1 setting.

c Dentist office or dental clinic, pharmacy, laboratory, public health setting, emergency medical services setting, or other setting where clinical care or related services was provided to patients.

d Allied health professional, technician, or technologist.

e Administrative support staff members or manager and nonclinical support staff members including food service workers, laundry workers, janitors, and members of the housekeeping and maintenance staff.

f Includes all respondents who indicated that their employer required them to be vaccinated for influenza.

g Employer made influenza vaccination available on-site for at least 1 day during the influenza season at no cost to employees. Restricted to respondents without an employer requirement for vaccination.

h Influenza vaccination was promoted among employees through public identification of vaccinated persons, financial incentives or rewards to individuals or groups of employees, competition between units or care areas, free or subsidized cost of vaccination, personal reminders to be vaccinated, publicizing the number or percentage of employees receiving vaccination, or making vaccination available at special events organized on site. Restricted to respondents without an employer requirement for vaccination or on-site vaccination.

By influenza vaccination status, the weighted percentage of respondents who expressed agreement with the vaccination requirement statement was 83.5% for those who received the vaccine and 33.9% for those who did not. Of those who agreed with the vaccination requirement statement yet did not receive it, the most common reasons given for not getting it were “I haven’t gotten around to it (18.0%),” “I just don’t want the vaccine (15.7%),” and “My employer didn’t require me to have a vaccination (14.1%).” By workplace vaccination promotion, the weighted percentage of respondents who expressed agreement ranged from 56.4% for those with no employer requirement, onsite vaccination, or promotion to 81.6% for those with an employer vaccination requirement.

Discussion

Mandatory influenza vaccination is increasingly common in healthcare settings, and multiple states have established influenza vaccination requirements for hospital HCP.Reference Stewart, Caplan, Cox, Chang and Miller 5 However, concerns have been raised related to the variable effectiveness of the vaccine and the ethical and legal impact of these policies.Reference Stewart, Caplan, Cox, Chang and Miller 5 , Reference Quan, Tehrani and Dickey 6 The duty of a HCP to protect the health of individual patients and the public competes with their right to personal autonomy. Mandates also invoke legal issues, including the applicability of state and federal constitutional laws and statutes.Reference Stewart, Caplan, Cox, Chang and Miller 5 , Reference Randall, Curran and Omer 7

Nevertheless, in our study, most HCP (72.9%) from all occupational groups and healthcare settings agreed with employer vaccination requirements. These findings suggest an increase when compared with a 2010 online research panel of HCP nationwide, showing that 57.4% of HCP agreed with influenza vaccination requirements.Reference Maurer, Harris, Black and Euler 4 Implementation of employer vaccination requirements is becoming more common (11.1% of respondents in 2010 compared with 42.3% in our study).Reference Maurer, Harris, Black and Euler 4 This finding is similar to those of other nationally representative samples among hospitals (43%–44%).Reference Miller, Ahmed, Lindley and Wortley 8 , Reference Greene, Fowler and Krein 9

In our study, employees in hospitals, ambulatory care, and long-term care settings had similar agreement with employer vaccination requirements (70.9%–77.2%). However, physicians, pharmacists, and nurse practitioners/physician assistants had the highest agreement with employer vaccination requirements (all >80%), and other clinical HCP (67.4%) and assistants/aides (69.9%) had the lowest agreement.

Nearly one-third of HCP not vaccinated agreed with the employer influenza vaccination requirement statement. Also, 56.4% of HCP work in settings without vaccination requirement, onsite vaccination, or promotion efforts in combination with vaccination requirements. These findings suggest that employer vaccination requirements, particularly in long-term care settings, could increase influenza vaccination coverage.

Notably, the survey question lacked details on what “required” vaccination entails. However, vaccine requirement is generally defined as any institutional policy that requires HCP to receive influenza vaccine or decline to receive one, with or without consequences for vaccine refusal.10 Examples of consequences include termination, mask wearing, and restriction from patient care duties. Exploring the consequences was outside the scope of this study.

Most HCP from all occupational groups and healthcare settings agreed with vaccination requirements, including 33.9% of those not vaccinated. Wider adoption of employer vaccination requirements in all healthcare settings has support, can increase HCP influenza vaccination, and may reduce influenza transmission in healthcare settings. Interventions known to improve coverage, such as educating workers and offering vaccine on site, at no cost, and during work hours should be implemented.
