Outline of Final Research Achievements

Multi-drugs-resistant A. baumannii (MDRAb) is associated with high morbidity and mortality as well as longer hospital stays in a hospital. We established a MDRAb-LAMP method for detecting blaOXA-23-positive MDRAb, which accounts for approximately 95% of MDRAb in Thailand. In this study, we evaluated the efficacy of rapid detection and intervention for nosocomial infection among ICU patients in Thai hospital. All the patients screened for MDRAb with both culture and LAMP by rectal swab and/or sputum (intubated patients only) on admission, weekly and on discharge. By using LAMP method as surveillance, we were able to reduce the rate of MDRAb transmission from 26.8 to 13.8 cases per 1000 patient days (p=0.03).MDRAb-LAMP enabled us to find positive patients and start appropriate interventions earlier and we were able to clarify the effect of rapid detection to reduce nosocomial infection.
