Objective: By implementing a focused must-have vaccination strategy (Easy Vaccination in Oncology [EVO]), we aimed to increase rates for high-impact vaccinations (Streptococcus pneumoniae, influenza, herpes zoster and hepatitis B) in the at-risk population of oncological patients.
Methods: In this German multicentre interventional non-randomised controlled two-arm open trial with repeated cross-sectional data collection, we evaluated the EVO strategy as an easy to implement approach. Vaccination rates were assessed in the outpatient setting and re-assessed after 3 months. A generalised linear mixed model (GLMM) was used to assess the primary endpoint (Streptococcus pneumoniae vaccination rates according to recommendations), taking clustering within clinics into account.
Results: Vaccination rates substantially increased in the intervention group; Streptococcus pneumoniae +21.5% (+16.7% according to recommendations), influenza +12.2%, herpes zoster +13.3% (+13.6% age group 50+), and hepatitis B +11%. Vaccination rates in the control group tended to decrease or increase only moderately (-5.8% [-3.8%], +7.4%, +2.1% [1.4%], and -1.7%, respectively). GLMM showed significant effect of the intervention (OR 7.50, 95% CI 2.18-25.80, p = 0.001).
Conclusion: This easy-to-implement and resource-saving approach has the potential to increase vaccination rates in oncological patients and to have a considerable impact protecting oncological patients from preventable infectious diseases.
Clinical trial registration: The study was registered at the German Resister for Clinical Studies (DRKS) under DRKS00020118.
