Intrahospital Influenza Vaccination in Patients at High Cardiovascular Risk (VACC-UP)

Официальное название

Intrahospital Vaccination and Active Counseling Versus Active Counseling Alone to Increase Seasonal Influenza immUnization in Patients at High Cardiovascular Risk in Germany: The Randomized Controlled VACC-UP Study

Обзор

The aim of this study is to evaluate the effect of offering intrahospital influenza vaccination as an adjunct to active counseling during the index hospitalization to adult patients hospitalized for acute coronary syndrome (ACS) or congestive heart failure (CHF), compared with active counseling alone, on influenza vaccination rates in patients at high cardiovascular risk. Patients are randomized 1:1 to either an offer of bedside intrahospital influenza vaccination according to the recommendations of the German Standing Vaccination Committee (STIKO) in addition to standardized active counseling (intervention group), or standardized active counseling plus the standard-of-care recommendation for ambulatory vaccination in the discharge papers (control group). The primary endpoint is the influenza vaccination rate at the end of the index season (March 31).
