BACKGROUND: The objective of this study was to compare antibiotic prescription rates in Denmark among elderly living in long-term care facilities to elderly living at home, with regards to total antibiotic use and antibiotic use for urinary tract infection.

METHODS: This is an observational registry-based study. The study population included all elderly Danish residents aged ≥75 years in 2016. Linear regression models were used to examine the difference in antibiotic prescription rates between elderly living in long-term care facilities and elderly living at home. Results were adjusted for age, sex and comorbidity, the latter assessed via the Charlson Comorbidity Index.

RESULTS: The study population consisted of 416,627 elderly. Regression models showed that elderly living in long-term care facilities were prescribed 1.7 [CI 1.7-1.7] prescriptions/individual/year more than elderly living at home. For urinary tract infections the difference between elderly living in long-term care facilities and elderly living at home was 1.2 [CI 1.2-1.3] prescriptions/individual/year.

CONCLUSIONS: Elderly living in long-term care facilities have a higher antibiotic prescribing rate than elderly living at home, despite controlling for age, sex and comorbidity. This indicates that long-term care facilities continuously should be a focus for antibiotic stewardship interventions.
