Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a medical information input system for creating a medical record at a medical site, and more particularly to an electronic medical record that uses a paper chart, determines the contents as an electronic medical record, and confirms the authenticity. The present invention relates to a handwritten electronic medical chart system for efficiently performing an act of initiating a guarantee of a document, that is, a definitive act.

[0002]

2. Description of the Related Art Some conventional electronic medical record systems use a keyboard or a mouse to input information necessary for an electronic medical record during medical treatment. When this is used, the doctor becomes the input work center, and there is a place that is inconsistent with the patient-centered medical care. Further, since the input load is high, it is avoided to input all the contents written on the paper chart into the electronic chart, and the amount of information required as the original chart tends to be insufficient. Also, it was difficult for doctors who are not used to keyboards and mice to introduce them. In order to cope with this problem, a handwritten electronic medical record system for creating an electronic medical record by handwriting has been proposed as shown in Japanese Patent Application Laid-Open No. 9-171528.

For example, FIG. 30 is a block diagram showing a schematic configuration of a device in a conventional handwritten electronic medical chart system. In the figure, reference numeral 1 denotes a handwriting input unit for inputting writing information using a tablet or the like. 2 is a personal authentication means,
This is a means for determining whether or not the user is a registered person using handwriting information (signature) obtained from the handwriting input means 1.
Reference numeral 3 denotes a character recognizing means for recognizing characters based on handwriting information obtained from the handwriting input means 1. Reference numeral 4 denotes storage means for storing handwriting information input from the handwriting input means 1 and recognition results output from the character recognition means 3, that is, text information. Reference numeral 5 denotes control means for controlling each of the means 1, 2, 3, and 4 to perform an operation according to the flowchart of FIG.

Next, the operation will be described with reference to the flowchart shown in FIG. First, the control unit 5 instructs the handwriting input unit 1 to collect handwriting information of a handwritten signature for authenticating a writer (step ST1).
0). Next, the handwriting information of the signature obtained by the handwriting input means 1 is sent to the personal authentication means 2, and the handwriting information of the signature is compared with the handwriting information of the previously registered registrant. (Step ST1)
1). If the determination result of the personal authentication unit 2 is “YES” (registrant), the process proceeds to step ST13 and subsequent steps. on the other hand,
If the result of the determination is "NO" (unregistered person), the process ends without doing anything (step ST12).

[0005] If the determination is "YES" (registrant), the handwriting input means 1 is instructed to collect handwriting information of the contents of the medical chart written by the registrant (step ST13). Next, the handwriting information collected by the handwriting input means 1 is sent to the character recognizing means 3 and converted into text information by performing character recognition (step ST14). The text information of the recognition result obtained by the character recognition means 3 is stored in the storage means 4 (step ST15).

[0006]

As described above,
A conventional handwritten electronic medical record system authenticates a registrant with a handwritten signature, and when authenticated, recognizes the contents of the medical record written by hand and converts it into a text to be stored. This system is stipulated in "Guidelines for preserving medical records and medical records in electronic media that require preservation by law" prepared by the Medical Information System Development Center in accordance with the guidelines of the Ministry of Health and Welfare. In requirements
The requirements for identification and certification of the author are fulfilled. However, since there is no means for performing a finalizing operation on the stored contents, the requirements for the finalizing operation of the above guidelines were not satisfied, and the electronic medical record was not recognized as a formal electronic medical record. In addition, since the electronic medical record information is not recognized as an electronic medical record under the law, paper medical records cannot be destroyed,
There is a problem in that one of the advantages of introducing an electronic medical record system, that is, the advantage of reducing the space for storing paper medical records, is lost.

If it is determined that the finalizing operation has been performed by storing the data in the storage means 4 and the finalizing operation is automatically performed, the person in charge of preparation (often the attending physician)
Will not be sufficiently checked. In other words, when a medical record is created by multiple persons, the information entered by anyone other than the person in charge of the creation is treated as finalized, and the checks required for the original finalization are not followed, which may lead to medical errors. there were. Further, even when the definitive action is performed before being stored in the storage means 4, since there is no means for supporting the definitive action, all the input contents must be checked. This has a problem that it does not conform to the actual situation when considering the burden on doctors in medical practice. Furthermore, it is necessary to perform the definitive action during the day of medical treatment (within 24 hours), which also makes the prior check difficult.

[0008] In the conventional system, the creator is authenticated at the start of chart creation, but the writer is not rechecked with respect to the handwriting information of the created chart. For this reason, there is a problem that a person other than the person who is authenticated at the time of starting cannot check if a medical record is subsequently entered, and cannot prevent alteration of the medical record by a malicious person.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and satisfies the requirements as an electronic medical record system by enabling input handwriting information to be determined. It is an object of the present invention to obtain a handwritten electronic medical record system capable of realizing preservation.

This invention classifies and saves handwriting information for each writer, and adds and displays writer information according to the classification result to the handwriting information, thereby discriminating information entered by a person other than the writer. It is an object of the present invention to obtain a handwritten electronic medical record system that reduces check work at the time of confirmation.

Further, the present invention can reduce medical errors by extracting important keyword information (for example, cautions for handling, treatment information) preset from handwriting information and displaying it in an identifiable manner. The purpose is to obtain a handwritten electronic medical record system. Further, according to the present invention, medical information updated along with the keyword is prepared in advance,
When keywords are detected, their related information is additionally displayed so that even if the doctor does not have the latest information at hand, the system can present the information on a high-quality medical practice. The purpose is to obtain a handwritten electronic medical record system that can be provided regardless of the location.

FIG. 28 is a display screen of the display unit 11 showing handwriting information that makes it possible to identify a writer other than a specific writer.

The operation of the electronic handwriting system according to the second embodiment will be described with reference to the flowchart of FIG. The processing in steps ST10 to ST12 is the same as that of the conventional example and the first embodiment. It is assumed that the handwriting information shown in FIG. 3 is obtained in step ST19 as in the first embodiment, and the handwriting information is stored in the handwriting information storage unit 10 in step ST20. In the next step, the control means (b) 60 instructs the handwriting information classification means (b) 61 to classify the handwriting information stored in the handwriting information storage means 10 by writer (step ST30).

The classification processing procedure of the handwriting information classification means (b) 61 will be described with reference to the flowchart of FIG. First,
The handwriting information classifying means (b) 61 sends the handwriting information to the grouping means 62 and performs a classification process (step ST31).
The operation of the grouping means 62 is shown in the flowchart of FIG. The grouping means 62 creates a Y-direction histogram as shown in FIG. 17 from the input handwriting information (step ST40). Grouping means 62
Extracts a "line" using the Y-direction histogram (step ST41). Specifically, a continuous black area of the obtained histogram is cut out as one “row”. In the example of FIG. 17, since there are three black areas 81, 82, and 83, they are cut out into three lines. The clipped result is shown in FIG.

The grouping means 62 creates an X-direction histogram for each of the cut-out lines (step S).
T42). The example of FIG. 19 is a histogram created for the handwriting information of the first line (line number “1”). Using the information of the histogram 91 in the X direction, the grouping unit 62 cuts out character blocks in units of the handwriting information in groups (step ST43). Among the continuous black regions in FIG. 19, the black regions in which the region width of the histogram in the X direction falls within a certain range are integrated and cut out as one group. The extracted character blocks are classified into two groups as illustrated in FIG.

Next, the grouping means 62 applies the extracted group information, that is, the character block to the group information shown in FIG.
As shown in the figure, the writing start time 93 and the writing end time 94
Ask for. Then, the writing end time 94 and the writing start time 93
If the difference is equal to or larger than a certain threshold, regrouping is performed so that the difference falls within the threshold (step ST44). Here, assuming that the threshold is 1 minute, the group “1” falls within the threshold, but the group “2” does not fall within the threshold. In this example, as shown in FIG. 22, the group 2 is divided into two, because it is within the threshold value by being divided into handwriting information of “temperature measurement” and “39 degrees 5 minutes”. In the same manner, the same processing is performed for all “rows”, and finally, a group classification result as shown in FIG. 23 is obtained.

Next, returning to the flow chart of FIG. 15, the handwriting information classifying means (b) 61 instructs the character recognizing means 63 to convert the grouped handwriting information into characters by recognizing the characters, and the same between groups. Characters to be detected are detected (step ST32). The character recognition of the grouped handwriting information is performed by the method described in the document "Study of Online Freehand Character String Recognition Method", Information Processing Society of Japan 61st National Convention 5V-6. FIG. 24 shows a character recognition result 202, that is, text information.

The handwriting information classifying means (b) 61 checks whether the same character exists (step ST33).
If the same character exists, it is determined whether or not the handwriting is written by the same person based on the handwriting information of the same character (step ST).
34). Judgment as to whether or not the same person wrote is performed by using, for example, the personal authentication means 2 with respect to each character.
This is performed by a handwriting collation method as described in 1-238131. In this example, two identical characters “5” and “9” are detected in groups 3 and 6 in FIG. Since these two characters are written by the same person, they are determined to be the same.

Next, the handwriting information classification means (b) 61 determines whether or not there is a group determined to be the same (step ST35). If they are the same, step ST36
If not, the process proceeds to step ST37. In this example, since there is a group determined to be the same,
Proceeding to step ST36, the groups to which the characters determined to be the same belong are regrouped as the same group.
In this example, the group “3” and the group “6” in FIG.
Are integrated and rearranged as a group “3” in FIG.

Next, the handwriting information classifying means (b) 61 checks whether or not the processing has been completed for all groups (step ST37). In this example, "NO" because all groups have not been grouped yet.
Is determined, and the process returns to step ST32. Step ST3
2, the handwriting information classifying means (b) 61 performs the same character detection operation again between the groups. In this example, however, the same character exists between two or more groups since the reorganization has already been performed. No, the same character is not detected again.

Thereafter, the process proceeds to step ST33, where the handwriting information classifying means (b) 61 checks whether the same character exists. In this example, since the same character does not exist anymore, "N"
O "is determined. In response to this determination, the handwriting information classifying means (b) 61 determines the identity between the groups by calculating the average writing pressure and the average writing speed (the speed at which the brush is carried) within the group (step ST38). ). For each group, an average writing pressure 205 and an average writing speed 206 are calculated from the handwriting information in the group 205 as shown in FIG. First, the average pen pressure “12” in the group “1”
For “0”, a group that falls within the threshold of the pen pressure to be treated as the same group is determined. Here, the pen pressure threshold is set to 5
Then, since the group “2, 4, 5” is within the range of the threshold value, it is set as the same group candidate as the group “1”. Next, similarly, it is determined whether or not the average writing speed 206 is within the threshold value of the writing speed. Here, assuming that the threshold of the writing speed is 0.5, the group candidate “2, 4, 5” is determined to be the same group because the difference from the average writing speed of the group “1” is within the threshold. You. Finally, the groups “1, 2, 4, 5” are determined to be the same group.

After checking the identity of the average writing pressure 205 and the average writing speed 206, the handwriting information classifying means (b) 61 determines whether or not the same group exists (step ST35). Since there is a group determined to be the same group in step S
Proceed to T36. Next, the group “1, 1,
"2, 4, 5" are classified as handwriting of the same writer (step ST36). In this example, since all grouping has been completed for all groups, it is determined to be "YES" (step ST37), and the handwriting information classifying means (b) 6
The process of No. 1 ends. Figure 2 shows the final classification result.
6 is shown. As shown in the figure, the handwriting information (coordinate information) is 2
Scribes "A, B".

When the processing (step ST30) of the handwriting information classifying means (b) 61 ends, the flow returns to the flowchart of FIG. The display means 11 displays the handwriting information stored in the handwriting information storage means 10 together with the result of the handwriting information classification means (b) 61 (step ST22). FIG. 27 shows the screen contents of the display means 11 in this example. In the figure, the writer information 220 is added to the handwriting information (coordinate information), and the same effect as in the first embodiment can be obtained. Subsequent steps 23 and 24
Is the same processing operation as in the first embodiment, and the description thereof is omitted.

In the above description of the second embodiment, the grouping means 62 has performed grouping using two-dimensional handwriting information and time information. Instead, as in the first embodiment, after grouping based on pen attribute information such as a pen ID or terminal information, grouping may be performed using the character recognition unit 63.

In the display means 11, when the handwriting information is displayed, the writer information is added and displayed. However, as in the first embodiment, even when the handwriting information is displayed so as to be identified by the color information and the layout information. Good. Further, in the display of the display means 11, the determined information and the undetermined information are displayed without being distinguished, but only the undetermined information is displayed, or the undetermined information and the determined information can be distinguished. May be displayed as follows.
Further, when the handwriting information is displayed on the display means 11, the writer information is added to all the handwriting information and displayed. However, the handwriting information other than the specific writer (for example, the person performing the determination) is added. Only for this, the scribe information may be added and displayed. FIG. 28 shows an example in which writer information (writer B) is added only to handwriting other than writer A in FIG.

When the "rows" are cut out by the grouping means 62, the histogram in the Y direction is used. However, the present invention is not limited to this, and if a similar effect can be obtained, the "rows" may be cut out using another method. Is also good. Also, the grouping means 62
In the above, the grouping of the handwriting information in the “line” is performed using the histogram in the X direction. However, the present invention is not limited to this, and the grouping of the handwriting information may be performed using other features if a similar effect is obtained. May go. Further, the grouping means 6
In 2, the determination was made using the pen attribute information of the average writing pressure and the average writing speed as the handwriting information. However, the determination is not limited to this, and the pen writing information such as the average writing acceleration, the maximum writing pressure, and the minimum writing pressure can be obtained. The classification may be performed using any handwriting information.

In the handwriting information classifying means (b) 61, the threshold for judging whether or not the groups belong to the same group based on the average writing pressure and the average writing speed is fixed.
