Abstract

Background: Standardized infection ratio (SIR) is a new measure used in surveillance of healthcare-associated infections, and cumulative attributable difference (CAD) is another new measure complementary to SIR. This study aims to calculate the SIR and the CAD for central line-associated bloodstream infection (CLABSI) and catheter-associated urinary tract infection (CAUTI) at the national level in 2017.
Material and Methods: Predicted number of CLABSI and CAUTI for the SIR and the CAD calculation was calculated by the formulas obtained from the negative binomial models using the national surveillance data in 2016 and the SIRs and CADs calculated for the data in 2017.
Results: The average length of stay and hospital type are available in both models. While the CLABSI model has also ICU branch and number of hospital beds, the CAUTI model has catheter utilization ratio and the number of ICU beds. The standardized CLABSI ratio was 0.87 (95% CI:0.85-0.90) and the standardized CAUTI ratio was 0.84 (95% Cl:0.82-0.86). The CAD for CLABSI and CAUTI was 697.26 and 659.76, respectively. 59.4% of the ICUs reached 25% reduction target for CLABSI and the 67.8% of the ICUs for CAUTI.
Conclusion: The SIRs and the CADs in this study proof that Turkey has achieved success in the implementation of infection control measures in the ICUs for CLABSI and CAUTI, however, this ought to be improved further. We hope that our findings shall be guiding and encouraging for other countries.
