Factors influencing uptake of influenza A (H1N1) vaccine amongst healthcare workers in a regional pediatric centre: Lessons for improving vaccination rates

BackgroundInfluenza A (H1N1) vaccination has been recommended for all frontline healthcare workers (HCWs) in the UK since October 2009, to protect individuals and their patients from infection. Understanding the factors influencing vaccine uptake by HCW may improve future vaccination programmes in current and subsequent years.AimsTo assess the uptake of influenza A (H1N1) vaccine, and factors affecting vaccine uptake, in frontline healthcare workers in a large pediatric hospital.MethodA cross-sectional questionnaire survey conducted in a regional Pediatric Hospital in Scotland incorporating intensive care and ECMO services. One page, anonymised questionnaires were distributed to all frontline HCW in high risk departments of the hospital.Results260 questionnaires were completed, capturing an estimated 52% of all staff. Vaccination rate was 49.6%, and was significantly higher amongst doctors (OR 2.4, 95% CI 1.3–4.5, P = 0.005). Commonest reasons for vaccine uptake were high risk of contact with H1N1 (88%) and responsibility to protect patients (71%). Uncertainty about vaccine side-effects (47%), concern about vaccine safety (33%) and being too busy to attend the vaccine clinic (22%) were the commonest reasons for non-vaccination. Reasons for vaccination varied between staff grouping and department. 36% of non-vaccinated staff would accept the vaccine if offered.ConclusionsVaccine uptake may be increased by addressing HCW knowledge and attitudes and access to vaccine. Future vaccination programmes should include targeted education and vaccine delivery, at the convenience of staff, and in their own department.

► Influenza A (H1N1) vaccine uptake rate amongst frontline healthcare workers in this regional UK pediatric centre was 50%.
► Vaccination uptake was significantly higher amongst doctors than other staff.
► Perceived high risk of H1N1 contact was the commonest reason for vaccine uptake.
► Non-vaccination was associated with issues of accessibility and vaccine knowledge and attitudes.
