Bacteriological Profile in the Catheter Associated Urinary Tract Infection (CAUTI) Patients in a Tertiary Care Hospital of Uttarakhand, India
Keywords:CAUTI, UTI, CLED Media, HAI, E. coli.
Introduction: UTIs are the most common type of healthcare-associated infection (HAI). Among UTIs acquired in the hospital, approximately 75% are associated with a urinary catheter. According to the CDC, Catheter associated urinary tract infections (CAUTIs) are defined as an UTI developing in a patient after 48 hours of implantation of an indwelling urinary catheter. Materials and Methods: The present study was a cross sectional study, conducted over a period of one year.A total of 468 subjects (patients) were included in this study.Before enrolling patients into study, an informed written consent from each patient was taken.Taking all aseptic precautions and following CDC guidelines, Urine samples of catheterized patients received and sent for bacterial culture and sensitivity in the Microbiology section of Central laboratory (an ISO 15189:2012 certified, NABL accredited Laboratory) of SMIH, Patel Nagar, Dehradun. Out of 468 patients, only 100 were culture positive and were processed and reported as per the standard methods. Results: In our study we found that Escherichia coli (53%) were the predominant bacteria isolated, followed by Klebsiella Pneumoniae (16%). Minimum (1%) isolation was seen for Enterococcus casseliflavus.Maximum number of cases were from age-group of 71-80 years (18%) followed by 61-70 years (16%) and least number of cases from age-group of 1-10 years & 91-100 years (1%) each. The prevalence of CAUTI was more in females (53%) than in males (47%). Conclusion: Based on this study, we conclude that Catheter associated urinary tract infections (CAUTI) are one of the most common nosocomial infections. Escherichia coli are found to be the most common causative organism followed by Klebsiella Pneumoniae, responsible for CAUTI in a tertiary care hospital of north India. Advanced age and female sex are more vulnerable group to get CAUTI. To avoid device associated infections, it is required to establish a standard guideline for the indwelling urinary catheter management.
