BACKGROUND: The prevalence of health care-associated infections (HAIs) in general medical wards at Siriraj Hospital in Bangkok, Thailand remains at 10% even after infection control measures were launched. The present study aimed to determine the effectiveness of comprehensive individualized bundling infection control measures in reducing HAIs and to identify the lowest possible rate of HAIs in general medical wards. METHODS: This was a cluster randomized controlled study conducted in 8 general medical wards (4 control wards and 4 intervention wards) at Siriraj Hospital. The patients hospitalized in the control wards received regular health care, as well as regular measures for preventing HAIs. The patients hospitalized in the intervention wards received additional measures. Each patient in the intervention wards was visited by the infection control team once a day until he or she left the hospital. The infection control team identified risk factors for developing HAI in each patient, coordinated with the local health care team to eliminate or minimize such risk factors, and encouraged responsible personnel to comply with the appropriate infection control measures for each patient. RESULTS: Between January and April 2009, there were 954 patients (9,650 hospitalization-days) in the intervention wards and 920 patients (9,777 hospitalization-days) in the control wards. The patient characteristics were comparable in the 2 groups. The prevalence of HAI was significantly lower in the intervention wards compared with the control wards (5.6% vs. 9.2%; P = .003). Six episodes of HAI in patients in the intervention wards could have been avoided. CONCLUSION:Comprehensive individualized bundling infection control measures were effective in reducing the prevalence of HAIs in general medical wards. The target overall prevalence of HAIs in general medical wards should not exceed 4.9%.
