Abstract
Introduction: Urinary Tract Infection (UTI) is a disease that often occurs in developing countries after upper respiratory tract infections. The incidence of UTI in 2018 in Indonesia is quite high, ranging from 39-60%. Antibiotics are the main therapy for UTIs, but excessive and inappropriate use of antibiotics can cause occurrence of antibiotic resistance. Objective: This study aims to quantitatively analyze patterns of antibiotic use in UTI patients at the NTB Provincial Hospital in 2019. Methods: This type of research is descriptive in nature using a cross-sectional design. There were 47 patients in case who were diagnosed with UTI ith the ICD-X code N39.0, which means the UTI suffered by the patient was a non-specidic type of UTI. Quantitative use of antibiotics was calculated using the ATC/DDD method according to WHO standards. Results: The total value of DDD/100 Patient-days was 51.26 with ceftriaxone as an antibiotic with the highest DDD/100 patient-days value of 19.78 and had the largest value in the 90% DU segment, which was 38.59%. Conclusion: Regular evaluation of antibiotic use is needed to minimize excessive use of antibiotics so that rational antibiotic use can be achieved.
