Abstract

Objective: The aim of the study was to report the results of the International Nosocomial Infection Control Consortium (INICC) study conducted from May 2008 to March 2015.

Methods: A device-associated healthcare-acquired infection surveillance study in three adult intensive care units (ICUs) and 1 neonatal ICU from 4 hospitals in Vietnam using U.S. the Centers for Disease Control and Prevention's National Healthcare Safety Network (CDC/NHSN) definitions and criteria as well as INICC methods.

Results: We followed 1592 adult ICU patients for 12,580 bed-days and 845 neonatal ICU patients for 4907 bed-days. Central line-associated bloodstream infection (CLABSI) per 1000 central line-days rate was 9.8 in medical/surgical UCIs and 1.5 in the medical ICU. Ventilator-associated pneumonia (VAP) rate per 1000 mechanical ventilator-days was 13.4 in medical/surgical ICUs and 23.7 in the medical ICU. Catheter-associated urinary tract infection (CAUTI) rate per 1000 urinary catheter-days was 0.0 in medical/surgical ICUs and 5.3 in the medical ICU. While most device-associated healthcare-acquired infection rates were similar to INICC international rates (4.9 [CLABSI]; 16.5 [VAP]; 5.3 [CAUTI]), they were higher than CDC/NHSN rates (0.8 [CLABSI], 1.1 [VAP], and 1.3 [CAUTI]) for medical/surgical ICUs, with the exception of CAUTI rate for medical/surgical ICU and CLABSI rate for the medical ICU. Because of limited resources of our Vietnamese ICUs, cultures could not be taken as required by the CDC/NHSN criteria, and therefore, there was underreporting of CLABSI and CAUTI, influencing their rates. Most device utilization ratios and bacterial resistance percentages were higher than INICC and CDC/NHSN rates.

Conclusions: Device-associated healthcare-acquired infection rates found in the ICUs of our study were higher than CDC/NHSN US rates, but similar to INICC international rates. It is necessary to build more capacity to conduct surveillance and prevention strategies.
