RESUMEN
Purpose: To analyze the quality of infection control activities, bacteriological data relevant to infection control was evaluated through the microbiological data warehouse networking hospitals in two medical regions. Methods: Data regarding bacterial test results of 19 hospitals were extracted from two microbiological laboratory information data bases. The rate of MRSA among total S. aureus was used as a general indicator of infection control activities. The occupancy rate of nasal or pharyngeal swabs among MRSA-positive bacteriological samples was used as an indicator of attention paid for infection control in intensive care wards. The number of blood culture sets per examined patient was utilized as an indicator for life-long vocational education on updated medical practice relevant to infectious diseases. Results: The rate of MRSA was significantly higher in secondary private hospitals. The occupancy rate of nasal or pharyngeal swabs was significantly higher in tertiary hospitals. The average number of blood culture set per examined patient were 1.55, 1.54 and 1.39 in tertiary, secondary public and secondary private hospitals, respectively; however, there were no statistical differences between groups. Conclusions: Data bases of microbiological test results shared by hospital laboratories are useful for evaluating regional infection control activities.
