Background
Influenza is a major complication in cancer and hematopoietic cell transplant (HCT) recipients. We set out to maximize influenza vaccination rates in healthcare personnel at our large ambulatory cancer center with high baseline compliance and to assess alternatives to mandatory policies.
Methods
Baseline influenza vaccine compliance rates at our center were over 85%. In 2011 an incentive-based “carrot” campaign was implemented, and in 2012 a penalty-based “stick” approach to declining staff was required. Yearly approaches were compared using Kaplan-Meier survival estimates.
Results
Both the incentive and penalty approaches significantly improved upon the baseline rates of vaccination (2010 vs. 2011 [p=0.0001]; 2010 vs. 2012 [p<0.0001), but 2012 significantly improved over 2011 (p<0.0001). Staff with direct patient contact had significantly higher rates of vaccination when compared to those with indirect and minimal contact in every campaign year, except in the penalty-driven campaign from 2012 (p<0.001, <0.001, 0.24, and p<0.001, <0.001, 0.17, respectively).
Conclusion
A multifaceted staff vaccination program that included education, training and active declination was more effective than one offering incentives. Improvements in vaccination rates in the penalty-driven campaign were driven by staff without direct care responsibilities. High compliance with system-wide influenza vaccination was achieved without requiring mandatory vaccination.
