Risk Factors for Central Line Associated Bloodstream Infections in 41 Countries

Multinational prospective study of incidence and risk factors for central line-associated bloodstream infections in 728 ICUs of 41 Asian, African, Eastern European, Latin American and Middle Eastern countries over 24 years

 

Objective: Identify central line (CL)-associated bloodstream infections (CLABSI) incidence and risk factors (RF) in low and middle-income countries (LMIC).

Design: From 07/01/1998 to 02/12/2022, we conducted a multinational multicenter prospective cohort study using online standardized surveillance system and unified forms.

Setting: 728 ICUs of 286 hospitals in 147 cities in 41 African, Asian, Eastern-European, Latin-American, and Middle-Eastern countries.

Patients: 278,241 patients, followed during 1,815,043 patient-days, acquired 3,537 CLABSIs.

Methods: The CLABSI rate had CL-days as denominators and the number of CLABSIs as numerators. Using multiple logistic regression outcomes are shown as adjusted odds ratios (aOR).

Results: Pooled CLABSI rates is 4.82 CLABSI per 1,000 CL-days, significantly higher than the CDC NHSN. We analyzed 11 variables, and following variables were independently significantly associated with CLABSI: Length of stay (LOS), rising risk 3% daily (aOR=1.03;95%CI=1.03-1.04;p<0.0001), number of CL-days, rising risk 4% per CL-day (aOR=1.04;95%CI=1.03-1.04;p<0.0001), surgical hospitalization (aOR=1.12;95%CI=1.03-1.21;p<0.0001), tracheostomy use (aOR=1.52;95%CI=1.23-1.88;p<0.0001), hospitalized at a publicly-owned facility (aOR=3.04;95%CI=2.31-4.01;p<0.0001) or at a teaching-hospital (aOR=2.91;95%CI=2.22-3.83;p<0.0001), located at a middle-income country (aOR=2.41;95%CI=2.09-2.77;p<0.0001). ICU with highest risk was adult-oncology (aOR=4.35;95%CI=3.11-6.09;p<0.0001), followed by pediatric-oncology (aOR=2.51;95%CI=1.57-3.99;p<0.0001), and pediatric (aOR=2.34;95%CI=1.81-3.01;p<0.0001) ICU. CL with the highest risk was internal-jugular (aOR=3.01;95%CI=2.71-3.33;p<0.0001), followed by femoral (aOR=2.29;95%CI=1.96-2.68;p<0.0001). PICC (aOR=1.48;95%CI=1.02-2.18;p=0.04) was the CL with the lowest CLABSI risk.

Conclusions: The following CLABSI RFs are unlikely to change: country income level, facility ownership, hospitalization type, and ICU type. Based on these findings it is suggested to focus on reducing LOS, CL-days, and tracheostomy; using PICC instead of internal-jugular or femoral; and implementing evidence-based CLABSI prevention recommendations.
