Are medical residents a 'core group' for future improvement of influenza vaccination coverage in health-care workers? A study among medical residents at the University Hospital of Palermo (Sicily).

摘要

Despite international recommendations, vaccination coverage among European healthcare workers, including physicians, is widely recognized as unsatisfactory. In order to plan tailored vaccination campaigns and increase future coverage, we investigated reasons for refusing vaccination and determinants associated with influenza vaccine uptake among young health care workers. A survey was carried out during September and October 2010 on medical residents attending post-graduate Schools of the Medical Faculty at the University of Palermo (Italy). Each participant completed an anonymous web-based questionnaire including items on demographic and occupational characteristics, knowledge, attitudes and behaviours with regard to influenza and influenza vaccination, and main sources of information. A total of 202 (66.9%) out of 302 medical residents participated in the survey. During the 2009-2010 influenza vaccine campaign, 44 residents (21.8%) were vaccinated against seasonal influenza and 84 (41.6%) against pandemic influenza A (H1N1) 2009. For the impending 2010-2011 influenza season, 45 (22.3%) stated their intention to get vaccinated against seasonal influenza, 40 (19.8%) were uncertain and 117 (57.9%) were opposed. Considering themselves to be a high risk group for developing influenza was significantly associated with vaccination against both 2009-2010 seasonal (adj-OR=1.46; 95% CI=1.05-2.04) and pandemic A (H1N1) influenza (adj-OR 1.38; 95% CI=1.08-1.75). Intention to get vaccinated against 2010-2011 seasonal influenza was significantly more frequent in participants who had a high perception of efficacy/safety (adj-OR=1.49; 95% CI=1.05-2.12). After adjusting for confounding, vaccinations against seasonal 2009-2010 influenza, pandemic influenza A (H1N1) 2009 and seasonal 2010-2011 influenza were significantly more frequent in residents who were vaccinated against influenza at least once in the previous five influenza seasons. Influenza vaccination among medical residents appears to be habitual, with little comprehension of the rationale and logic for vaccination, including the need to be vaccinated to protect patients from nosocomial influenza infection. Our study suggests the importance of prioritizing residents for vaccination campaigns, as they represent "the future" and include a core group that habitually accepts vaccination.
