Outline
Text
Background: Influenza vaccination coverage in Germany does not meet the recommendation of the World Health Organization. Nursing home residents are an especially vulnerable subgroup. It is not known whether vaccination coverage rates differ between nursing home residents and non-institutionalised persons of the same age group.
Objectice: We aim to find out whether influenza vaccination coverage differs for nursing home residents between the year before and after admission and what determines the chance to receive vaccination.
Methods: Claims data of the health insurance fund DAK-Gesundheit of at least 65 years olds were used. The proportion of residents with influenza vaccination were compared in the year before and after the admission stratified by several covariates. A multivariate logistic regression analysis was conducted to obtain predictors for influenza vaccination after admission.
Results: Overall vaccination coverage was higher in the year after admission (53.0%) than before (38.3%). Differences in vaccination coverage between most covariates evened out after admission. Differences remained for region of residence and number of comorbidities. The strongest predictor for receiving a vaccination after admission was the vaccination status before admission (OR: 3.5; 95%-CI: 3.3-3.6) followed by region and number of comorbidities.
Discussion: Clear and unambiguous evidence of vaccine safety and efficacy for different subgroups within the same age group as well as organisational efforts to increase vaccination within nursing homes would be recommended.
