| Outline of Final Research Achievements |
For early detection of outbreaks of nosocomial infections, monthly occurrences of some pathogenic bacteria in wards are analyzed in many hospitals. However, systematic statistical procedures to evaluate these data have not been established yet. We analyzed time series of methicillin-resistant Staphylococcus aureus (MRSA) detections in Niigata University Medical and Dental Hospital to elucidate the stochastic structure of nosocomial infections. Our results showed that the time series of MRSA detections satisfies the features of a Poisson process, and enabled the strict calculations of probabilities and statistical evaluations of the observed data.
