Impact of Targeted Interventions on Trends in Central Line-Associated Bloodstream Infection: A Single-Center Experience From the Republic of Korea.
OBJECTIVE
To assess the impact of targeted interventions on trends in central line-associated bloodstream infection.


METHODS
A before-and-after study between January 2013 and September 2014.


METHODS
Tertiary hospital in the Republic of Korea.


METHODS
All patients with central-line catheters in the hospital.


METHODS
In September 2013, interventions that targeted central line insertion practices were implemented in 10 ICUs, including compliance monitoring with a central line insertion practices bundle and use of an all-inclusive catheter kit. The impact of targeted interventions on trends in central line-associated bloodstream infection was evaluated by segmented autoregression analysis of an interrupted time series.


RESULTS
The average hospital-wide central line-associated bloodstream infection rates in the baseline and intervention periods were 1.84 and 1.56 per 1,000 catheter-days, respectively. During the baseline period, there was an increase of central line-associated bloodstream infection rate of 0.12 per 1,000 catheter-days per month. In the intervention period, there was a decrease of central line-associated bloodstream infection rate of 0.16 per 1,000 catheter-days per month (change in slope, -0.28; 95% CI, -0.37 to -0.19; p < 0.0001). In ICUs, the average central line-associated bloodstream infection rates in the baseline and intervention periods were 1.92 and 1.64 per 1,000 catheter-days, respectively. During the baseline period, there was an increase of central line-associated bloodstream infection rate of 0.18 per 1,000 catheter-days per month in ICUs. After sequential-targeted interventions, there was a decrease of central line-associated bloodstream infection rate of 0.16 per 1,000 catheter-days per month (change in slope, -0.34; 95% CI, -0.50 to -0.18; p = 0.0007).


CONCLUSIONS
Targeted interventions were associated with significant changes in trends in the occurrence rate of central line-associated bloodstream infection in ICUs and the entire hospital.
