Clinical and microbiological profile of patients with urinary tract infection visiting general outpatient department, National Referral Hospital

Abstract

Background: Urinary Tract Infection (UTI) is one of the most common infections encountered in outpatient settings. The random use of antibiotics, particularly in resource-limited settings, has contributed to the emergence of antibiotic resistance. This study aimed to identify common uropathogens and assess their antibiotic sensitivity patterns among patients with symptoms of UTI attending the General Outpatient Department (GOPD) at Jigme Dorji Wangchuck National Referral Hospital in Thimphu.

Method: A cross-sectional study was conducted from September 2021 to August 2022, involving patients over the age of 13 years with symptoms of UTI. Midstream urine collected via proper technique was analyzed by the laboratory. Once there was growth on the urine culture media, antibiotic sensitivity testing was performed against the commonly used antibiotics in the GOPD.

Result: Amongst 351 participants, 77.8% were female, and the most common symptoms reported were dysuria (93.4%) and increased urinary frequency of micturition (92.3%). Patient’s age, sex and previous episodes of UTI were significantly associated with the occurrence of UTI (p < 0.05). The overall urine culture positivity rate was 50.53%, with Escherichia coli (84.7%) identified as the predominant uropathogen, followed by Klebsiella pneumoniae (7.3%). Among the antibiotics tested, gentamicin and nitrofurantoin exhibited the highest sensitivity, while amoxicillin and ampicillin were the least effective antibiotics against Escherichia coli.

Conclusion: UTI predominantly affected females. Escherichia coli was the commonest causative agent and nitrofurantoin could be the potential drug of choice for UTI treatment. The irrational use of antibiotics, as a contributing factor to resistance should be addressed.
