Frequency and Antibiotic Susceptibility of Pathogens from Cases of Urinary Tract Infection: A Prospective...

Objectives  Urinary tract infection (UTI) is one of the most common diagnoses in patients visiting urology clinics. Rampant use of empiric and inadequate doses of antibiotics leads to an increase in resistance and poses a huge financial burden. We evaluated UTI in relation to antibiotics used, frequency, susceptibility, and resistance pattern of different pathogens at a tertiary care center and made some important observations. Methods  Prospectively 729 patients diagnosed with UTI attending a urology outpatient department from July 2018 to January 2020 were managed accordingly. Antibiotics were started on the basis of urine culture and sensitivity (c/s) or empirically and changed according to subsequent urine c/s. Repeat urine c/s was performed after 5 to 7 days of starting therapy and 10 days after completion of therapy. Results  Out of 729 subjects, 417 (57.2%) were males and 312 (42.8%) were females. The most common symptom at diagnosis was dysuria 512 (70.2%), whereas 221 (30.3%) patients presented with fever. Escherichia coli was the most common organism isolated, 453 (62.1%). Among 729 patients, 239 took antibiotics without c/s report, whereas in 490 patients antibiotics were prescribed after the report. A total of 431 (59.1%) patients required one antibiotic session for clearance of pathogen, whereas 135 (18.5%) required two sessions, and three sessions were required in 66 (9%) cases. Among 239 patients whose culture came out to be positive, 145 (60.6%) were found to be resistant to the previously given antibiotic and the common pathogens isolated were E. coli (61 [42%]), Pseudomonas (28 [19.3%]), Enterococcus (22 [15.1%]), Klebsiella (14 [9.6%]), and others. Conclusion  Unchecked, rampant, and inadequate use of antibiotics leads to complicated UTI with the increasing share of Pseudomonas, Klebsiella , or other dangerous microbes, which are difficult to treat as well as pose threat in the future.
