BackgroundInfluenza vaccination is highly recommended for nursing home residents. However, it is known that vaccination coverage is low in the general population.AimsWe aim to find out whether influenza vaccination coverage differs for nursing home residents between the year before and after admission and factors determining the chance to receive vaccination.MethodsClaims data of the health insurance fund DAK of at least 65-year-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.ResultsVaccination coverage was overall 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.DiscussionOverall, vaccination coverage of nursing home residents remains lower than recommended. Doctor–patient contacts whether due to care for comorbidities or as a continuation of the relation over the time of admission to the nursing home seem to assure vaccination for residents.ConclusionClear and unambiguous evidence of vaccine safety and efficacy for different subgroups within the same age group as well as organizational efforts to increase vaccination within nursing homes would be recommended.
