Abstract : Background Central line-associated bloodstream infection (CLABSI) is the most common hospital-acquired infection. However, studies evaluating the factors associated with the risk of CLABSI in pediatric intensive care units (PICU) were limited in India. Objective The objective of our study is to evaluate the association of factors and the etiology causing CLABSI. Study design This is a hospital-based single-center prospective study conducted in the pediatric intensive care unit (PICU) of our tertiary care hospital spanning one year. Participants Children aged between two months to 15 years admitted in the PICU for more than 48 hours with central venous catheterization were included. Pearson's chi-squared test with Yates' continuity correction and logistic regression with odds ratio were calculated by R statistical software (R Foundation for Statistical Computing, Vienna, Austria) and a p-value less than 0.05 was considered statistically significant. Results Our analysis showed that factors such as young age (2-12 months), high pediatric risk of mortality (PRISM III) score (> 15), leukocytosis, neutrophilia, anemia, change of central venous catheter, duration of catheterization (>7 days), exposure to blood products, use of steroids, inotropes, and prophylactic antibiotics were significantly associated with increased risk of CLABSIs with an odds ratio of 4.53, 4.54, 2.91, 4.56, 4.76, 3.74, 2.49, 2.41, 7.22, 6.77 and 5.16 respectively (p<0.05). Further, factors such as older age (>12 months) and low PRISM III score (≤ 15) significantly reduce the risk of CLABSIs by 83.64% and 69.14% respectively (p<0.05). Conclusion In conclusion, our results revealed that factors such as young age, high PRISM III score, leukocytosis, neutrophilia, anemia, change of central venous catheter, duration of catheterization (> 7 days), exposure to blood products during the hospital stay, use of steroids, inotropes, and prophylactic antibiotics were identified as risk factors for CLABSI.
