Coverage of annual influenza vaccination of healthcare workers (HCWs) varies and remains at a sub-optimal level in many countries | Journal of Hospital Infection
As HCWs are often exposed to a variety of information on vaccination, their pattern of exposure may impact their decision, which deserves further investigation.
Practising nurses in Hong Kong were invited to participate in an anonymous online survey in February 2015, after the winter seasonal peak. The questionnaire covered demographics, work nature and experiences, vaccination uptake history and reasons for vaccination decisions. Two categories of behaviors with regards to information access were defined – (A) passive exposure to information, and (B) active information-seeking, as differentiated by the source, type and nature of information accessed. Chi-square test, Mann-Whitney U test, logistic regression were performed to compare between vaccinated and unvaccinated nurses.
A total of 1177 valid returns were received from nurses who had a median age of 32, of whom 86% were female. The overall vaccination rate was 33%. Passive exposure to information from workplace, professional body and social network did not predict vaccination decision, while mass media did (OR:1.78). Active information-seeking involving consulting seniors (OR:2.46), having organized promotion activities (OR:2.85) and performing information search (OR:2.43) were significantly associated with increased vaccination uptake. Cumulative effect could be demonstrated for active information seeking (OR:1.86) but not passive exposure to information.
Current strategy of promotions and campaigns for seasonal influenza vaccination in HCWs may not be effective in increasing vaccination coverage. Measures targeting information-seeking behaviors may serve as an alternative approach.
