Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an infectious disease monitoring method and monitoring system for monitoring and managing infectious diseases in medical institutions such as hospitals and clinics, and in particular, early detection of the occurrence of infectious diseases and quick response is possible. The present invention relates to an infectious disease monitoring method and a monitoring system.
[0002]
[Prior art]
In the medical service related to infectious diseases in hospitals, medical practice such as examination, examination, and medication is performed for each patient. The information system used throughout these tasks handles individual test results on a patient basis. Therefore, even if an inpatient is infected in the hospital, whether it is incidentally caused by infection alone, or infection specific to the ward, ward, department, etc. It was extremely difficult to distinguish whether the infection was prevalent in the hospital due to the source. Therefore, the current situation is that the detection of outbreaks in the hospital depends on the experience and intuition of doctors, nurses, laboratory technicians, and the like.
[0003]
The occurrence of nosocomial infections may lead to death in hospitalized patients whose immunity has deteriorated in the worst case, and it is desired that they be detected as early as possible.
[0004]
As a method for monitoring the status of nosocomial infection, for example, a technique described in JP-A-7-79929 is known. This technology examines the infection status of various bacteria, acquires the bacterial species data of the carrier into the bacterial species data file, and then determines the bacterial type from the bacterial species data in the bacterial species data file and the resident position data of the carrier. The in-hospital distribution data of the carrier is created, and the in-hospital distribution of the instructed bacteria type carrier among the in-hospital distribution data is visually output.
[0005]
[Problems to be solved by the invention]
The technique described in Japanese Patent Application Laid-Open No. 7-79929 is based on the premise that a hospital periodically inspects the state of infection with various bacteria. However, because there are so many types of bacteria, it is practically difficult to regularly test all bacteria and check for signs of epidemic.
[0006]
As described in the above-mentioned conventional technology, in reality, it is necessary to check whether the infection status is to be tested, and to check the occurrence frequency for each bacterium and various external environmental factors in order to catch the signs of the epidemic. Rely on the experience and intuition of doctors, nurses, laboratory technicians, etc. In this case, if it is late to notice the epidemic due to mass infection or its precursors, there is a possibility that a so-called outbreak occurs, in which an outbreak occurs.
[0007]
An object of the present invention is to provide an infectious disease monitoring system that can detect the occurrence of a mass infection as early as possible and enable early countermeasures.
[0008]
[Means for Solving the Problems]
