Room: Poster Hall B1


Background:Influenza (flu) vaccination of health care workers (HCW) is associated with reduced morbidity among patients and is a cost effective measure for health care institutions because of reduced HCW illness and absenteeism. Despite recommendations by the CDC for flu vaccination of HCW, vaccination uptake among HCWs remains low.

Methods:Mandatory flu vaccination of all HCW was implemented for the 2010-11 flu season at our tertiary care center that included the Karmanos Cancer Center (KCC) and the Detroit Medical Center (DMC). Approximately 15,000 HCWs were eligible for flu vaccination. HCW refusing vaccination were required to wear respiratory masks during direct patient contact throughout the flu season. Educational campaigns were conducted by occupational health and infection control personnel prior to and after implementation. At KCC, HCWs who refused vaccination were asked to sign declination forms that included reasons for refusing vaccination.

Results:Overall flu vaccination rates among HCWs increased from 62% to 92%. In general hospitals the increase was 42% to 64% as compared to 66% to 89% at KCC. Immunization rates were highest among HCW in units housing BMT patients. The reasons for refusing vaccination noted by 58 HCW at the KCC were: 64% - personal beliefs/no reason; 31% - allergy to vaccine/prior reaction; 5%-medical conditions e.g.  Guillan-Barre syndrome.

Conclusion:Despite significant improvements to the flu vaccination rates using a mandatory vaccination program, barriers to immunization remain. Improved understanding of the true reasons for refusal by HCW of flu vaccination is necessary to direct future educational efforts and vaccination campaigns.
