Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nosocomial infection status diagnosis method and apparatus for diagnosing the infection status of various microorganisms such as bacteria in a hospital.

[0002]

2. Description of the Related Art Nosocomial infections are constantly changing in characteristics due to the aging of patients and heavy use of various drugs. In particular, nosocomial infections of MRSA (methicillin-resistant Staphylococcus aureus) become a social problem. ing.

Here, nosocomial infection is defined as "an infectious disease newly infected by an inpatient in a hospital apart from the original disease, or an infectious disease caused by a medical worker (in-hospital worker) in the hospital". The source of infection is microorganisms (bacteria, viruses, fungi, protozoa, etc.) that are transmitted to humans, such as infected persons, carriers, contaminated instruments, and machines.

This outbreak of bacterial infection in the hospital has a reason different from that of the general public, and it is due to a decrease in immunity specific to inpatients, contact between carriers in a closed building, and insects. It is considered to be caused by the propagation by

Further, it is also considered that one of the causes is that the clothes of medical staff such as doctors and nurses, the sheets of the hospital bed, and the like are contact-infected with bacteria, and the bacteria are transmitted to other hospital rooms.

[0006] Due to such a cause of infection, death may occur when a patient with post-operative immunity is infected.

[0007] Therefore, in order to minimize such nosocomial infections, the infection status should be detected accurately and early,
It is necessary to take measures.

[0008] Therefore, various methods have been proposed in order to statistically grasp such a situation of nosocomial infection. For example,
"Statistical forecast of infectious disease epidemics due to trends and seasonality" (No. 1
2nd Joint Conference on Medical Informatics 12th JCM1 NO
V. 1992) is a well-studied statistical method in that the situation of infection is captured in a time series.

[0009]

However, only the method of grasping the increase / decrease in the infection situation on a nationwide scale has been proposed, and it is still unsolved that the infection situation in one hospital can be accurately grasped. .

An object of the present invention is to provide a nosocomial infection status diagnosis method and apparatus capable of accurately grasping the infection status in one hospital.

[0011]

In order to achieve the above object, the method of the present invention is a method for inspecting an inpatient in a hospital and an in-hospital worker such as a doctor or a nurse for infection with various bacteria. After acquiring the bacterial species data of the carrier in a bacterial species data file, the hospital-specific distribution data of the bacterial species-specific carriers is created from the bacterial species data of the bacterial species data file and the resident position data of the carrier, and the hospital-specific distribution data is obtained. Among these, the in-hospital distribution of designated bacterial carriers is visually output, and the in-hospital distribution of bacterial carriers is diagnosed based on the output result.

[0012] In addition, bacterial strain data at different inspection times are acquired in the bacterial strain data file, and the in-hospital distribution data of the bacterial strain carrier is inspected from the bacterial strain data of the bacterial strain data file and the resident position data of the bacterial strain carrier. Created by period, visually output the in-hospital distribution of designated carrier among the inpatient distribution data by inspection time by inspection time, and diagnose the in-hospital distribution by inspection time of bacterial inoculation carrier by this output result It is something that is done.

Further, the device of the present invention is an inspection means for inspecting inpatients in hospitals and in-hospital workers such as doctors and nurses for infections of microorganisms such as various bacteria, and a carrier of the results. The in-hospital distribution data of the strain-specific carrier is created from the storage means that stores the strain data in the strain data file, and from the strain data in the strain data file and the resident position data of the strain carrier. A data processing means for visually outputting the in-hospital distribution of the instructed bacterial carriers of the designated bacteria type is provided.

[0014]

According to the above means, after the infection state of various bacteria is inspected and the bacterial species data of the carrier is acquired in the bacterial species data file, the bacterial species data of the bacterial species data file and the resident position of the carrier are obtained. From the data and the data, the hospital distribution data of carriers of different types of bacteria is created, and the in-hospital distribution of the carriers of specified bacteria is visually output from this in-hospital distribution data, and the in-hospital distribution of carriers of different types of bacteria is diagnosed by this output result. Therefore, it is possible to accurately grasp the infection status in one hospital.

In addition, since the bacterial species data at different inspection times are acquired in the bacterial species data file and the in-hospital distribution of the bacterial carriers of the bacterial species is visually output according to the inspection time, the time-series hospital distribution of the bacterial carriers of the bacterial species can be calculated. Can be diagnosed.

A position data file 6 to be stored, a bacterial species data file 7 to store bacterial species data for each carrier, and a contamination status data file 8 to store data indicating the hospital distribution of bacterial carriers by bacterial type.

As shown in FIG. 2, the position data file 6 stores a patient ID 21, a name 22 and bed position coordinate data 23. Similarly, for medical workers such as doctors and nurses, unique IDs and coordinate data of resident positions such as nurse stations are stored. In this case, the coordinate data is composed of three-dimensional data consisting of a floor and plane coordinates on the floor.

As shown in FIG. 3, the bacterial species data file 7 comprises a patient ID 21 at the beginning and all bacterial species codes 32-1 to 32-m of the bacterial species infected by the patient. The bacterial species code 32 is stored for each patient and each medical staff. Here, m represents the maximum value of the number of bacterial species that the patient is infected with.

Furthermore, the pollution status data file 8 contains
As shown in FIG. 4, the inspection date and time is set to the beginning, and the bacterial species code 42
0 and a plurality of position coordinates in which the bacterial species are distributed (coordinates such as a patient's bed position and a resident position of a nurse) 421-1 to 42-1
Nosocomial distribution data 42-1 of carrier type carriers consisting of 1-q
42-j are stored.

Here, j represents the maximum value of the number of bacterial species discovered by inspection, and q represents the maximum value of the number of distribution positions of each bacterial species.

For example, when the patient 1 is hospitalized and discharged, the patient ID 21, name 22 and bed position coordinate data 23 are input from the input / output device 4 and stored in the position data file 6 (step 50). The same applies when the medical staff 2 is relocated.

FIG. 6 is a flowchart of the processing performed when the contamination inspection apparatus 3 performs the inspection. For example, if the contamination inspection is performed on the patient 1 and the medical staff 2 by the culture identification inspection method, the inspection date (the microorganism to be inspected) Date of collection), patient ID 21 (including medical worker ID), and the code 32 of the bacterial species found in the test results are input from the input / output device 4 (step 60), and the patient ID 21 and bacterial species code are input through the host computer 5. 32 is stored in the bacterial species data file 7 (step 61).

Next, the patient ID from the position data file 6
Using as a key, the position coordinates of the patient and medical staff are acquired (step 62).

Next, from the bacterial species data of each patient in the bacterial species data file 7 and the position coordinate data of the patient and the medical staff, the contamination status data showing the in-hospital distribution of carriers of the bacterial species is prepared, and the contamination status data file 8 is created. In the format shown in FIG. 4 (step 63).

FIG. 7 is a detailed flow chart of the process for creating the contamination status data of the bacteria-type carriers. First, the bacteria species code = i is set (step 70). i is a code indicating one of all assumed bacterial species n.

Next, after setting the patient ID to the initial value (step 71), it is judged whether or not all bacterial species have been completed (step 72). If all the bacterial species have not been completed, the patient ID holding the bacterial species i is searched from the bacterial species data file 7 (step 73), and the position coordinate data of the patient with the searched patient ID is searched (step 74). The inspection date / time 41 and the bacterial species code 420 are added to the position coordinate data and registered in the contamination status file 8 in the format shown in FIG. 4 (step 75).

Next, it is judged whether or not the survey of the possession status of the bacterial species i has been completed for all the patients (including medical personnel) (step 76). The strain code is updated in order to investigate the possession status of, and the same process is repeated again.

When all patients (including medical staff) have not completed the survey of the possession status of the bacterial species i, the patient I
D is updated (step 77) and the possession status of the next patient is checked.

As a result, the contamination status data file 8 for each inspection time is prepared in the format as shown in FIG.

FIG. 8 is a flow chart of a process for visually outputting the in-hospital distribution of carriers designated by type of bacteria in the contamination status data by inspection time thus created, by the inspection time. When the "time series graph display" command is input from, this process is started.

First, when a bacterial species and a display period from the input / output device 4 are designated (step 80), the designated bacterial species,
The pollution status data for the display period is the pollution status data file 8
Is read out from (step 81).

Next, the number of detections per unit area, that is, the number of carriers is calculated for each floor, and displayed on the screen of the input / output device 4 in the format shown in FIG. 9 (step 82,
83).

With such a graph display, it is possible to accurately grasp the temporal variation in the number of carriers.

FIG. 10 is a flow chart of a process for visually outputting the in-hospital distribution of carriers of bacteria by floor for each floor. This process is started when a command of “display distribution state” is input from the input / output device 4.

First, from the input / output device 4, the bacterial species, the display period,
When the floor is designated (step 100), the pollution status data at the time of the inspection during the designated display period is read from the pollution status data file 8 (step 10).
1).

Next, the number of carriers on each floor during the designated display period is calculated, and the number of carriers on the designated floor is displayed in time series as shown in FIG. 11 (step 102).

As a result, it is possible to accurately grasp the distribution and temporal variation of the carrier number on the designated floor. Then, appropriate measures can be taken to prevent an increase in carriers.

In addition to the floor distribution and the time series distribution,
Distributions necessary for diagnosis can be created and displayed. Further, not only display output but also print output can be performed.
