Background
Little data exist on the burden of device-associated health care–associated infection
(DA-HAI) in China. This study examined the DA-HAI rate and evaluated its association
with device use (DU), length of stay (LOS), and mortality in intensive care units
(ICUs) in 4 Chinese hospitals.
Methods
This was a prospective cohort surveillance study conducted in 7 ICUs in 4 hospitals.
We applied International Nosocomial Control Consortium methods and Centers for Disease
Control and Prevention (CDC)/National Health and Safety Network (NHSN) definitions
to determine rates of central line–associated blood stream infection (CLABSI), ventilator-associated
pneumonia (VAP), catheter-associated urinary tract infection (CAUTI), DU, crude extra
length of hospital stay (LOS), and mortality.
Results
Between August 2008 and July 2010, there were a total of 2,631 admissions to the 7
ICUs in the study hospitals. The rate of VAP was 10.46/1,000 mechanical ventilator
(MV)-days, the CLABSI rate was 7.66/1,000 central line (CL)-days, and the CAUTI rate
was 1.29/1,000 urinary catheter (UC)-days. Pooled DU ratios were 0.43 for MV, 0.71
for CL, and 0.76 for UC. Crude extra LOS was 15 days for patients with CLABSI, 20.5
days for patients with VAP, and 27 days for patients with CAUTI. Crude extra mortality
was 14% for patients with CLABSI, 22% for patients with VAP, and 43% for patients
with CAUTI.
Conclusions
In the study ICUs, VAP and CLABSI rates were higher than CDC/NHSN's reported data,
and LOS and mortality were increased. Compared with the CDC/NHSN and INICC data, the
pooled DU ratio for MV was similar, and DU ratios for CL and UC use ratios were slightly
higher.
