P-1149. Reducing Central Line-Associated Bloodstream Infections (CLABSI) Using Bundled Care Strategies: A 3-Year Follow-up Study

TL;DR

A 3-year study in an Indian hospital showed that using bundled care strategies significantly reduced bloodstream infections and saved costs.

Contribution

Demonstrates the effectiveness of CLABSI prevention bundles in a resource-limited Indian ICU over three years.

Findings

CLABSI rates dropped from 8.9 to 1.7 per 1000 catheter-days over three years.

Hand hygiene compliance increased from 58% to 91%.

The intervention saved 490 ICU bed-days and INR 28.6 lakh in costs.

Abstract

Central Line-Associated Bloodstream Infections (CLABSIs) significantly increase morbidity, mortality, and healthcare costs, especially in resource-limited settings. Bundled care strategies have demonstrated efficacy in high-income settings, but evidence from secondary care hospitals in India remains scarce. This study evaluates the impact of implementing a CLABSI prevention bundle over a 3-year period in a tertiary-level hospital in rural South India.

A prospective, quasi-experimental study was conducted from January 2022 to December 2024 in a 12-bed adult ICU. The intervention included strict adherence to a CLABSI prevention bundle: hand hygiene, maximal sterile barrier precautions, chlorhexidine skin antisepsis, optimal catheter site selection, and daily assessment of line necessity. Baseline CLABSI rates were recorded for 6 months prior to intervention. Data were analyzed using Poisson regression and χ² tests for significance.

At baseline, the CLABSI rate was 8.9 per 1000 catheter-days. Following bundle implementation, the rate declined to 5.1 in year 1, 2.8 in year 2, and 1.7 in year 3 (p < 0.001). Overall, there was a reduction of 80.9% in CLABSI rates over 3 years. Hand hygiene compliance improved from 58% to 91% (p < 0.001), and adherence to full bundle components increased from 42% to 87% (p < 0.001). The intervention prevented an estimated 49 bloodstream infections, translating to approximately 490 ICU bed-days saved and a cost saving of INR 28.6 lakh (∼USD 34,400).

Implementing bundled care strategies in a resource-limited Indian ICU substantially reduced CLABSI rates and healthcare costs. Sustained leadership support, nurse-driven audits, and ongoing training were critical to success.
