Abstract
Background: The risk of healthcare-associated infections is increasing due to the increasing use of long-term care facilities (LTCFs). Identifying LTCF patients at high risk for antimicrobial-resistant urinary tract infection (UTI) is important for empirical antimicrobial therapy.
Methods: A retrospective case-control study was performed at a Seoul Medical Center (500-bed public hospital) between September 1, 2015 and August 31, 2016. We selected LTCF patients by reviewing medical records.
Results: Of 196 patients with a UTI during the study period, 52 were from an LTCF. Antimicrobial-resistant UTI was found in 53.8% (n=28) of LTCF patients. Logistic regression model identified 2 clinical factors associated with antimicrobial-resistant UTI: dementia (odds ratio [OR], 0.088; 95% confidence interval [CI], 0.014–0.531) and readmission within 1 year (OR, 12.247; 95% CI, 1.982–75.693).
Conclusion: Clinical factors can be used to identify antimicrobial-resistant UTI in LTCF patients to aid in the selection of antibiotics.
