Abstract
Introduction / objectives
Intensive care units (ICUs) are unfortunately the epicenters of nosocomial infections.
Limited data is available regarding burden of healthcare associated infections (HAIs)
in Indian ICUs, especially the rates of device associated infections by using standardized
definitions.
Methods
We conducted a prospective surveillance of device associated infections from January
2010-December 2010 in a 10 beded Medical ICU of Fortis Escorts Hospital, Jaipur. CDC-NNIS
system definitions for all device associated infections were used and rates were calculated
per 1000 device days. Device utilization ratio was calculated by dividing the total
number of specific device days by the total number of patient days. Microbiological
profile of each HAI was noted.
Results
435 patients were admitted in the Medical ICU representing 3080 patient days. The
overall DANI (device associated nosocomial infection) rate was 4.36% (19/435) or 6.16
(19/3080) DAI per 1000 ICU days. The overall VAP rate was 8.9 infections per 1000
ventilator days, CLABSI rate was 2.74 infections per 1000 central day and CAUTI rate
was 1.50 infections per 1000 catheter days. Device utilization ratio for central line,
ventilator and urinary catheter was 0.59, 0.36 and 0.86 respectively. Non fermenters
Gram negative bacteria accounted for 73.68% infections followed by Enterobacteriaceae
(21.05%). The most common bacteria were Acinetobacter baumannii (26.31% of total)
and Pseudomonas aeruginosa and Klebseilla pneumoniae (10.52% of total each).
Conclusion
Targeted surveillance and calculation of device associated infection rates per 1000
device days allows detection of unique institutional problems that need redress.
