Per Urethral Catheterisation: Microbial Growth Incidence and its Management

Singh M, Kothiyal P, Mathur P


The urinary tract is the most common site of nosocomial infections accounting for more than
40% of the total number reported by acute care hospitals and affecting approximately 600,000 patients per year. Catheter Associated Urinary Tract Infection (CAUTI) defines in terms of “bacteriuria” and “urinary tract infection” frequently. Bacteriuria or funguria levels >103 colony- forming units (CFU) have been shown to be highly predictive of CAUTI, given that
these levels increase to 105 CFU within 24 to 48 hours. In Indian population, catheterassociated urinary tract infection (CAUTI) is an important cause of morbidity and mortality,affecting all age groups. Biofilm is the predominant mode of growth in aquatic ecosystems and, as such, plays a central role in the pathogenesis of Catheter Associated Urinary Tract Infections (CAUTI). The present review focuses to evaluate the incidence and pattern of microbes in catheter associated urinary tract infection and provides information about the etiology of CAUTI. Most of the studies concluded that gram negative pathogen E.coli showed the highest incidence rate and other pathogens like Klebsiella pneumonia, Pseudomonas aeruginosa, and staphylococcus species also having the incidence rate in the patient having CAUTI. The antibiotic resistance pattern showed the variation in resistance and sensitivity of antibiotics against the pathogens. The present study focuses on the incidence of the microbial growth in patient having catheterization and also elucidates the antibiotic sensitivity pattern. It is necessary to determine the antibiotic resistance and sensitivity status during and after the catheterization
