Workplace interventions associated with influenza vaccination coverage among health care personnel in ambulatory care settings during the 2013-2014 and 2014-2015 influenza seasons
Vaccination of health care personnel (HCP) can reduce influenza-related morbidity and mortality among HCP and their patients. This study investigated workplace policies associated with influenza vaccination among HCP who work in ambulatory care settings without influenza vaccination requirements.Methods:
Data were obtained from online surveys conducted during April 2014 and April 2015 among nonprobability samples of HCP recruited from 2 preexisting national opt-in Internet panels. Respondents were asked about their vaccination status and workplace policies and interventions related to vaccination. Logistic regression models were used to assess the independent associations between each workplace intervention and influenza vaccination while controlling for occupation, age, and race or ethnicity.Results:
Among HCP working in ambulatory care settings without a vaccination requirement (n = 866), 65.7% reported receiving influenza vaccination for the previous influenza season. Increased vaccination coverage was independently associated with free onsite vaccination for 1 day (prevalence ratio [PR], 1.38; 95% confidence interval [CI], 1.07-1.78 or >1 day PR, 1.58; 95% CI, 1.29-1.94) and employers sending personal vaccination reminders (PR, 1.20; 95% CI, 0.99-1.46). Age ≥65 years (PR, 1.30; 95% CI, 1.07-1.56) and working as a clinical professional (PR, 1.26; 95% CI, 1.06-1.50) or clinical nonprofessional (PR, 1.28; 95% CI, 1.03-1.60) were also associated with higher coverage. Vaccination coverage increased with increasing numbers of workplace interventions.Conclusions:
Implementing workplace vaccination interventions in ambulatory care settings, including free onsite influenza vaccination that is actively promoted, could help increase influenza vaccination among HCP.
