Catheter-associated urinary tract infections (CAUTI) being the commonest hospital-acquired infection (HAI) [40%], its burden, aetiology along with antibiotic susceptibility is essential to implement and monitor an effective infection control program.
To assess the incidence and rate of CAUTI in a tertiary care hospital and to identify the common organisms and their antibiotic sensitivity pattern.
Prospective hospital based observational study was carried out in a tertiary care hospital in South Tamilnadu for a period of 2 months (June 2016 to July 2016) after obtaining the Institutional Ethics committee approval.
Total of 100 catheterized adult ICU patients were observed for signs of UTI on a daily basis. On clinical suspicion of UTI, urine sample was analysed microbiologically. CAUTI among various gender and age groups; pathogenic isolates, antibiotic sensitivity pattern and associated co-morbid conditions were expressed as percentages
Incidence of CAUTI was 16/100 catheterization. Device utilization ratio was 0.72. CAUTI rate was 36.2/1000 catheter days. CAUTI was commonly seen among patients with >80 years, females with altered sensorium. Diabetes mellitus (35.7%) was the most common comorbid condition followed by TB (25%). Risk of CAUTI after 3–5 days of catheterization was 11.7% and proportionately increased with prolonged catheterization (100% if >20 days). Escherichia coli (37.5%) followed by Candida Spp. (25%) were common pathogens among 3-5days of catheterization. Pseudomonas Spp. was the commonest isolate after one week of catheterization. Imipenem, colistin resistance was highest among pseudomonas.
CAUTI rate was higher than the benchmark set by NHSN (0–4). Appropriate health education, strict infection control practices, appropriate antibiotic policy, proper guided bundle care of catheter are need of the hour to prevent the CAUTI.
