Antimicrobial Sensitivity Pattern for Urine Isolates in Urinary Tract Infection

Abstract

Background: The increased frequency and management of antibiotic resistance pattern in urinary tract infection (UTI) is a challenging task for the clinicians. Therefore, the current study was planned to identify the microbial etiology of UTI and the most suitable antibiotics used. The objective of the study was to assess the frequency of antimicrobial sensitivity pattern in patients with urinary tract infection. Material and Methods: This cross-sectional study was carried out at Al Sayed Hospital, Kidney Centre, Rawalpindi over a period of seven months i.e. June 30, 2018 to January 30, 2019. A total of 152 patients were enrolled according to the inclusion and exclusion criteria of the study. Urine culture proceedings were done as per latest recommended guidelines of Clinical and Laboratory Standard Institute (CLSI) for UTI. Results: Highest sensitivity was observed for carbapenems (83.5%), followed by polymyxin B (72.3%), phosphonic acid derivatives (65.8%), aminoglycoside group (65.7%), extended spectrum penicillin (63.1%), imidazolidinedione (59.9%) and tetracycline (59.9%) groups. The least sensitivity was observed for Oxazolidinone (linezolid) (14.5%), teicoplanin (13.8%), tigecycline (10.5%) and first-generation cephalosporins (1.3%). Conclusions: Carbapenems showed maximum sensitivity for all urine isolates. The second and third options were polymyxin B and phosphonic acid derivatives, respectively.
