Antibiotic Usage and its Culture Sensitivity Pattern in Urinary Tract Infections at Tertiary Hospital in Eastern...

Background The presence of microbial pathogen in the urinary tract is Urinary Tract Infection (UTI). In BP Koirala Institute of Health Sciences (BPKIHS), each year there are around 1000 cases of UTIs. Antibiotic is empirically started after sending culture/sensitivity (c/s) with intention to change antibiotic if c/s demands. Objective To see the antimicrobial prescribing pattern and c/s pattern of UTI inpatients of BPKIHS together with their socio-demographic and laboratory profile. Method It was a Record-Based Retrospective Descriptive Study of past one-year. All available inpatient-records from Medical-Record Section were extensively searched for the keyword "UTI" diagnosis. The relevant data were entered in Microsoft Excel-sheet and analyzed with IBM SPSS 21. Ethical clearance was obtained from the IRC before study. Result There were 86 cases from four different wards. There was slight female preponderance (51.16%). Fifty-five (63.95%) cases were complicated. Fever (75.51%) was the most common symptom. Only 20% were tachycardic but 90% were tachypnic. Leucocytosis (59.26%), urine albumin within 30-100 mg/dl (33.85%) and >5 Urine WBC/hpf (80.26%) were seen. Ceftiaxone (53.16%) was the most commonly prescribed empirical antibiotic, followed by Cefixime (6.32%). Fourteen (16.27%) cases were culture positive. E. coli was the most (78.57%) common pathogen grown. In culture sensitivity study, Amikacin (42.85%) was the most sensitive antibiotic. Conclusion Eighty-six UTI inpatients were identified last year. Fever and Tachypnoea were very common. Leucocytosis, 1+ proteinuria and urine WBC>5/hpf were frequently seen. Ceftriaxone was the most common antibiotic prescribed. E. coli was the most common pathogen grown and Amikacin was the most sensitive antibiotic.
