Abstract
- BACKGROUND
The purpose of this study is to know the healthcare-associated infection (HAI)s in small and medium sized hospitals, less than 400 beds.
METHODS
We had web based surveillance for HAIs in 27 hospitals from August to October 2010. The surveillance performed in 1-2 ICUs and 1 general ward in each hospitals by CDC definition. And for the multi-drug resistant organisms (MDROs), we reviewed all of blood culture results.
RESULTS
We identified 319 HAIs among 269,436 patients days. The HAIs rate was 1.18 (CI 1.05-1.32)/1,000 patient-days. Urinary tract infection was the most common HAI (52.4%) in this study followed by pneumonia (18.9%), blood-stream infections (14.2%), surgical site infection (7.9%), and others (6.6%). There were 76.5% of device associated infections in UTI, 46.7% in BSI, and 18.3% in pneumonia. The rate of HAIs in ICU was higher than that of in general ward (4.6 vs 0.9/1,000 patient-days). However, the indwelling catheter associated urinary tract infection rate was lower in ICU (2.6 vs 4.4/1,000 device days). There were no significant differences in central line-associated blood stream infection rate (1.5 vs 1.8) and ventilator-associated pneumonia rate (3.0 vs 0.0). The common microorganisms found in HAIs were Escherichia coli (19.8%), Staphylococcus aureus (13.1%), and Pseudomonas aeruginosa (12.7%). Moreover, 90.9% of S. aureus were resistant to methicillin, and 38.2% of P. aeruginosa and 44.4% of Acinetobacter baumannii were resistant to imipenem. Total of 66 MDROs were isolated from blood culture and the result shows that the MRSA was 84.6% (56 case), carbapenmen-resistant Acinetobacter spp. was 10.6% (7 case), and vancomycin-resistant enterococci was 4.6% (3 case).
CONCLUSION
The characteristics of HAIs in small and medium sized hospitals will be contributed to the decision making of governance policy for infection control and to provide comparable data for these hospitals.
