[Influenza vaccination rates in Hessian hospitals]

Influenza infections have been shown to spread in hospitals rapidly; nosocomial transmissions occur frequently. Influenza vaccination of health care personnel (HCP) is an effective strategy for preventing influenza infections among personnel and patients. In summer 2011 we conducted an anonymous questionnaire among Hessian hospitals assessing influenza vaccination rates, kind and concept of vaccination programmes. Overall, 95.8% (68/71) of hospitals surveyed offered influenza vaccinations for HCP free of charge. Influenza vaccination rates have been recorded only by 70.4% (50/71). Over 80% (season 2009/2010: 41/50- season 2010/2011: 44/50) of hospitals questioned, mentioned influenza vaccination rates under 20%. Our findings confirm that the influenza vaccination rates might be less than the generally assumed and communicated influenza vaccination rates of 20-25%. Thirty years since the German Standing Committee on Vaccination (STIKO) recommended that all HCP get vaccinated against influenza, vaccination rates still remain below 30%. Measures to improve influenza vaccination rates among HCP are required. Monitoring of vaccination rates is a precondition to assess the acceptance of a vaccination programme.
