Abstract

PURPOSE:To attain smooth information transmission among respective departments by setting priority for each piece of information to be sent according to its request response speed and performing transmission control according to the priority. CONSTITUTION:A medical prescription order 105 from an outpatient examination section to a pharmacy, an inspection order 106 to an inspection subsystem, and an execution input order 107 to a medical accounting system are all information of an order system, so their priority levels are set relatively low. A patient order 108 from a host computer or an inspection result 109, etc., sent from the inspection subsystem to the outpatient examination section, on the other hand, is information of a reference system, so relatively high priority levels are set. Further, pieces 110 and 111 of information from a radiation section subsystem to a transmission and from the transmission line to a medical examination and operation assistance subsystem are both image information which is large in volume, so the priority is set lower than other code information. Thus, the priority is added as parameters and sent out to the transmission line.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hospital information system including registration, storage, storage and processing of medical information in a hospital, and more particularly, medical information for obtaining each information at a response speed required by a user. Information transmission method.

[0002]

2. Description of the Related Art In a conventional hospital information system, a doctor directly inputs instructions such as examinations and prescriptions to a terminal at the time of examining a patient, thereby digitizing order information and transmitting it to each department, and examination results etc. The medical information was treated by transferring the result information from each department to the terminal of the clinical department and referring to it. The typical system configuration and method are described in the Proceedings of the 12th Congress of Medical Informatics, pp. 227-230 (1992). In this case, various types of information have been transferred from the terminals, magnetic disks, etc. in each department or department to the intended receiving terminal via the network (prior art 1).

On the other hand, regarding the mechanism for controlling the priority of information to be transmitted on the network, "TCP / I
84-85 of "P" (Soft Research Center, 1989)
It is listed on the page. According to this, each data on the network is provided with a parameter area for priority control having a length of 3 bits, which makes it possible to give eight levels of priority (prior art 2). ).

[0004]

The above-mentioned prior art 1 enables the input of various information sources in a hospital, and thus the efficiency of various operations is being realized. However, various kinds of information are sent out on the transmission path without particularly considering the priority of transmission. Therefore, these response speeds cannot be controlled, and even if there is information that is desired to be obtained earlier, this cannot be transmitted with priority over other information. In addition, when sending a large amount of information such as image information to the network without restriction,
This becomes a bottleneck, and the flow of information may be delayed.

On the other hand, the prior art 2 describes a mechanism for controlling the priority of data on the network, but it is touched upon by what standard the priority is given to individual information. Not not. Particularly, in the hospital information system of the present invention, it is necessary to appropriately set the priority depending on the nature of each business in the hospital, but this is not mentioned at all.

An object of the present invention is to obtain various kinds of information in a hospital information system at a response speed required by a user.

[0007]

The above object is achieved by setting a priority for each information to be transmitted in advance according to the request response speed, holding this as a parameter, and performing transmission control thereby. It Specifically, a parameter giving the priority of information to be transmitted is set on the user program. Here, the value of the parameter is set for each job such as prescription order and inspection order. This is done by preparing a table in which the value of the priority parameter is set for each work in advance and referring to this. Then, the value of the parameter set in this way is set to OSI (Open Sys
tems Interconnection) and communicate to the highest level of the communication protocol. In response to this, the protocol is sequentially transmitted from the upper level to the lower level.
At the lowest level, each information is in the form of a packet, and the destination address is added to each packet. In addition to this, by adding the priority parameter transmitted from the higher level, Send it to the transmission line. On the transmission path, the priority of packet transmission is controlled according to the size of the priority parameter added to each packet.

[0008]

In the medical information transmission system of the present invention, the priority is set for each information to be transmitted in advance in accordance with the request response speed, and this is held as a parameter, whereby transmission control is performed. For example, in a hospital information system, there are order related information and reference related information. In this case, the former is the inspection order to the laboratory, the prescription order to the pharmacy, etc., and the patient's travel time from the input of these sources until the inspection or delivery of the drug is carried out. Since it is necessary, it is not necessary to request immediacy for the transmission of information. On the other hand, the latter is the reference of the test result, the reference of the prescription history, etc. Since these are the references of the information performed by the doctor during the medical treatment of the patient, it is essential to immediately transmit the information. . In this case, the object can be achieved by preferentially transmitting the latter as compared with the former.

Next, when comparing the information of the code system and the information of the image system, the capacity of the latter is remarkably larger than that of the former. Therefore, when the information is sent to the transmission line without distinguishing, the latter is It is expected that a bottleneck will occur and the transmission line will be congested, and the former transmission will be difficult. In this case, it is considered that such a failure can be avoided by lowering the priority of the latter transmission as compared with the former.

As shown in this example, a priority is set in advance for each piece of information to be transmitted in accordance with the request response speed, and transmission control is performed by this, so that smooth information transmission between departments is possible. Is possible. As a result, the priority given to each piece of information at the application level by the user is transmitted to the transmission path, and the priority control set by the user becomes possible.

1 shows an example of the configuration of a hospital information system according to the present invention and a priority control system for medical information according to the present invention. In the figure, 1 is a host computer, 2 is a system related to medical affairs and accounting, 3 is a pharmacy, which is one subsystem of a hospital information system, 4 is some outpatient department subsystems, and 5 is representative of various examination devices or systems. The inspection subsystem, 6 is a radiology subsystem representing the functions of the radiology department, and 7 is a surgery / treatment support subsystem. Reference numerals 101 and 102 denote backbone networks (LAN) that connect the subsystems to each other.

In the figure, the backbone network is a thick line 101.
There are two types, namely, the thin line 102 and the thin line 102. There are two types physically or logically, and the information on the thick line has high priority, and the information on the thin line has low priority. It indicates that there is. This figure shows an example of priority control depending on the data transmission direction and data capacity.As shown in the figure, the reference system information is more than the order system information, and the code system information is the image system. It is intended to be transmitted with priority given to the above information.

As the first priority control, the prescription order 105 from the outpatient department to the pharmacy, the inspection order 106 to the inspection subsystem, and the execution input order 107 to the medical accounting system are all order related information. , The priority is set relatively low. On the other hand, since the patient data 108 from the host computer or the examination result 109 sent from the examination subsystem to the outpatient department is reference system information, a relatively high priority is set.

As the second priority control, since the information 110 and 111 from the radiology subsystem to the transmission path, or from the transmission path to the treatment and surgery support subsystem are both large-capacity image information, other information is provided. Set lower priority than code information. In this way, the priority given to each kind of information is added to the information itself as a numerical parameter and sent to the transmission line.

A specific processing procedure from setting the priority parameter to sending it out to the transmission path will be described in detail with reference to the flowchart of FIG. 2 and FIGS. Here, the communication protocol applied to data transmission between subsystems is OSI.

Step 201: On the user program,
Set the value of the priority parameter of each information to be transmitted. According to the two priority controls, higher values are set for the reference system information than the order system information and the code system information than the image system information. Specific setting means of the value of the priority parameter in this case is as follows, for example. The business program being executed refers to a table in which the value of the priority parameter for each business is set as shown in FIG. 4 according to the content. This is set by the user in advance,
It can be set freely for each hospital. Here, the value of the priority parameter is set to four levels of levels 0 to 3. The larger the value, the higher the priority of the work.

According to the figure, level 0: prescription order, examination order, radiation order, surgery order level 1: injection order, treatment order level 2: radiological image reference level 3: prescription history reference, examination result reference, previous order It is a reference.

According to this, the priority of the reference work is set higher than that of the order work. Even the same order work is divided into level 0 and level 1 because the former work takes a longer time from the order issuance to the actual work than the latter. Further, even in the reference-related work, the radiation image reference work handles a large amount of image information, and thus the priority is set lower than other reference-related works.

Step 202: The value of each set priority parameter is transmitted to the highest level (application layer) of the communication protocol (OSI).

Step 203: The value of each priority parameter is sequentially transmitted from the upper level of OSI to the lower level. As shown in FIG. 3, OSI is composed of seven levels (layers) from the highest application layer to the lowest physical layer. Normally, on the transmitting side, protocol control information 301 is added to the data information 302 transmitted in each layer, and the integrated information becomes the data information at the level one level below. Such integration processing is repeated from the upper layer to the lower layer, and the data information becomes a bit string of 01 in the lowest physical layer. Then, this is divided into units called packets and sent out on the network. In the present invention, as shown in the figure, the priority parameter 30 is set together with the integration processing.
The value of 3 is also transmitted to the lowest physical layer.

Step 204: The value of the priority parameter 303 transmitted to the lowest physical layer is added to the packet in which each information is divided. Normally, only the destination address is added to each packet, but in the present invention, in addition to this, the value of the priority parameter is added.

Step 205: Send the packet to which the address of the transmission destination and the priority parameter are added to the network.

Step 206: The transmission priority of each packet is controlled by the size of the priority parameter. On the network, packets holding high priority parameters are preferentially transmitted.

Finally, the procedure of referring to the inspection result by applying the priority control according to the present invention will be described with reference to the block diagram of FIG. 1 and the flowchart of FIG.

Step 501: The doctor activates the ordering system with the IDs of the patient and the patient from the terminal in the medical department 4, and then selects the task of referring to the examination result.

Step 502: After the inspection result to be referred to is specified by the inspection item, inspection date, etc., a command is issued.

Step 503: The inspection result reference work program is executed, and the priority parameter setting table for each work as shown in FIG. 4 is referenced to set the value of the priority parameter. The value of the parameter is set to "3" by referring to this table.

Step 504: The set parameters are sent to the inspection subsystem 5 through the network 101 together with the reference command. This process is as described in the flowchart of FIG. In this case, since the value of the priority parameter is 3 which is the highest level, transmission is performed with priority over other information.

Step 505: Upon receiving the command and the priority parameter, the examination subsystem 5 sends back the designated examination result information to the clinical department 4 through the network 101 together with the priority parameter having the same value as when it was received. In this case as well, the priority parameter value is used to preferentially transmit other information.

Step 506: The inspection result information is displayed on the terminal in the medical department.

As described above, it is possible to actually control the priority by setting the priority for each business on the application side and sending the information together with the information to be transmitted onto the network.

According to the present invention, various kinds of information are transmitted according to the priority set by the user in advance, so that the information can be smoothly transmitted between the departments and stable system performance can be obtained.
