Background: Urinary tract infection (UTI) is a common health problem in both community and nosocomial settings. However, the predisposing factors which are responsible for production of extended spectrum beta-lactamase (ESBL) and carbapenem-resistant Enterobacteriaceae makes the treatment option narrow and cause multidrug resistance.
Aim and Objectives: This study demonstrate various risk factors associated with multidrug resistance in Enterobacteriaceae from UTI at tertiary care center in Gujarat.
Material and Methods: A retrospective observational study was conducted at a tertiary-care hospital. Urine samples were received from various departments and outpatient department (OPD). Organisms from Enterobacteriaceae group were isolated and identified by various biochemical methods. ESBL and Carbapenemase producing organisms were then processed for Antibiotic susceptibility test as per CLSI guideline.
Results: A total of 196 Enterobacteriaceae organisms were isolated from processed urine samples of tertiary care Hospitals. The most prevalent in people aged 45–65 years (36%) followed by those aged 17–30 (22%) years. UTI due to ESBL and Carbapenemase producer are more isolated in female (28%, 11%) as compare to male (16%, 6%). Indoor patients had higher prevalence of ESBL (29%) and carbapenemases (10%) isolation compare to OPD patient (ESBL-15%, Carbapenemases-7%) and among them most common ward was medicine department. The most common predisposing factor was catheterization followed by diabetes mellitus and obstructive uropathy.
Conclusion: High prevalence of ESBL and Carbapenemase producing Enterobacteriaceae is found in Indoor patients than OPD patients. Most of these patients are from Medicine department. Catheterization is the most common risk factor associated with ESBL and carbapenemase producing organism.
