Abstract
BACKGROUND: Vaccination against seasonal influenza in health workers is recommended but coverage is variable. This study aimed to determine coverage of influenza vaccination among health workers in Lima, Peru in 2010; explore barriers and enabling elements for vaccination; and suggest strategies to improve coverage.
METHODS: Qualitative interviews informed the development of a survey instrument that consisted of open and close-ended questions. Sub-analyses were done by occupational group and results were calculated as percentages for each possible response with confidence intervals of 95%.
RESULTS: Coverage of the influenza vaccination was 77.2%. Vaccinated staff were less likely to have permanent contracts (p=0.0150) and vaccination coverage was lower in physicians (p=0.0001). Over 90% cited protection of themselves, families and patients as reasons for vaccination and 48% mentioned peer encouragement. Fear of adverse events (47%) and organizational barriers (>30%) were reasons for non-vaccination. To improve coverage, highest priority was given to strategies providing more information.
CONCLUSIONS: Key factors in driving health worker vaccination include desire for protection and peer encouragement. Perceptual barriers based on a misunderstanding of the epidemiology of influenza and vaccination could be overcome by targeted education and information. Organizational barriers require attention to how vaccination is implemented within health facilities.
