Abstract:
BACKGROUND: It is well known that Methicillin-resistant Staphylococcus aureus (MRSA) is hardly controllable organism among pathogens of nosocomial infection. The MRSA infection control measures have been initiated at a brand new tertiary care teaching hospital which was opened in June, 1994. However, the control measures did bring out little effect. In 1997, reenforcement of all control measures were practiced in intensive care units. The measures brought out a significant improvement in reducing the incidence of MRSA infection, subsequently the same control measures were implemented through-out the entire inpatient area. METHODS: The following control measures have been reenforced since March 1997: first, application of thorough surveillance of confirmed MRSA infected patients: second, providing cohort care: third, enforcing handwashing practices after patient contact; fourth, establishing infected patients isolation zone: fifth, tagging infected patient's bed and medical record, providing disinfectant spray for washing hands, identifying and treating carriers among patient contact staffs, separate disposal of contaminated wastes, and finally repeating education of nursing staff and family members of the patients. Each month the number of incidence in MRSA nosocomial infection were followed and the leu supervisors were notified the outcome. RESULTS: The incidence of MRSA infection started to decline soon after the initiation of the control measures, from 132% in March 1997 to 5.8% in July 1997. In 1998, the infection rate maintained close to 2-3%. There had been 467 MRSA infected cases (5.7%) out of 8,253 discharges during the study period; among them 319 cases were infected once; 40 cases twice; 15 cases three times: four cases four times and 1 case seven times. The order of preference of organs infected are lungs (56.3%), wounds(11.8%), blood (7.9%), and urinary tract (1.9%). The highest incidence of this infection was found in Medicine (34.8%) and Neurosurgery (22.8%) CONCLUSION: The implementation and reenforcement of infection control measures are key to successful control of nosocomial infection, in particular, hand washing of patient contact staffs and eradication of carriers could be the most effective measures.
