Patent Application
20200365256
The present invention relates to a patient status determination device, a patient status determination system, a patient status determination method, and a patient status determination program recording medium.
In a hospital (especially, an acute care hospital), a situation where a person engaged in medical care (will be called a “medical staff person” hereinafter), such as a doctor or a nurse, is required to measure (determine) a status of a patient emergently transported thereto by an ambulance or the like takes place frequently. It may be presumed that the patient emergently transported is suspected to have a cerebrovascular disorder. In such a circumstance, the medical staff person is required to understand the status (e.g. paralysis, ataxia or the like) of the patient.
Measurement techniques for measuring (determining) the status of the patient suspected to have the cerebrovascular disorder have been known in this technical field. As one of the measurement techniques, there is the NIHSS (National Institute of Health Stroke Scale). In the NIHSS, on arrival of the patient at the hospital, before a treatment, and during the treatment, it is necessary for the medical staff person in charge to measure (determine) the status of the patient in question in every measurement period of fifteen minutes at the shortest. This is because the status of the patient is concerned in a treatment plan of the patient. It has been known that the NIHSS has thirteen items as items to be measured (determined). Accordingly, the medical staff person is required to perform a task (operation) of selecting a score for each item of the NIHSS within a measurement time interval (determination time interval) in every measurement period mentioned above. A total sum of scores of the respective items is equal to forty-two. In addition, the measurement time interval (determination time interval) is desirably as short as possible as compared with the above-mentioned measurement period and, for example, is preferably three minutes.
Various techniques related to this invention have been proposed.
For example, Patent Literature 1 discloses a system for classifying one or more subjects (patients) into one or more categories indicative of a health condition associated with the one or more subjects (patients). Patent Literature 1 describes that a health condition score may correspond to a stroke score such as a NIHSS score. Patent Literature 1 describes an example in which the NIHSS score is classified into four categories and then a doctor determines the degree of severity of the stroke based on the category into which the subject has been classified.
Patent Literature 2 discloses a remote medical system in which a diagnosis for a patient is performed by a doctor in a remote place. Patent Literature 2 describes, as one example of the remote medical system, a system which measures a body sound of a patient (subject to be measured) by using an electronic stethoscope at a medical site and records acquired electronic data, namely, body sound information. Such a remote medical system allows a diagnosing person such as a doctor in a remote place from the medical site to refer to the body sound information to use it for the diagnosis for the patient. In a measurement assistance device disclosed in Patent Literature 2, a display unit displays information (measurement scenario) for assisting a measurement activity of a measuring person and displays an operation screen as a GUI (Graphical User Interface) screen. Patent Literature 2 illustrates one example of a measurement assistance screen in which contents of the measurement scenario are reflected. The measurement assistance screen has an output area in which an auscultation procedure included in the measurement scenario is displayed, and an output area in which auscultation region visualization information is displayed. The measuring person confirms image data and starts auscultation in accordance with the measurement assistance screen. When acquisition of the body sound of the patient finishes, the measuring person taps a button.

PL 2: JP 2014-023715 A
In the above-mentioned NIHSS, the medical staff person (especially, an untrained and inexperienced medical staff person) may hesitate to determine a selection of a score for each item. As a result, it may possibly take a long time to measure (determine) the NIHSS. Therefore, it is desirable to resolve a problem of such hesitation of the medical staff person in decision on measurement (determination) and to shorten the measurement time interval (determination time interval).
However, the above-mentioned Patent Literatures 1 and 2 cannot resolve such problems.
That is, Patent Literature 1 merely discloses a technical idea of classifying a range of the NIHSS score into a plurality of categories. Accordingly, in Patent Literature 1, the medical staff person must, as ever, perform the above-mentioned task (operation) of selecting the score for each item of the NIHSS. Therefore, it is not possible to resolve the problems of the hesitation in decision on the measurement (determination) and of the measurement time interval (determination time interval).
On the other hand, Patent Literature 2 merely discloses the remote medical system in which the measuring person carries out the measurement (auscultation) for the patient and the doctor in the remote place performs the diagnosis by using a result of auscultation. In such a remote medical system, the measuring person merely performs an appropriate measurement for the patient by using a measurement instrument, such as the electronic stethoscope, in accordance with the measurement scenario. As described above, in the NIHSS, it is essential not only to perform the measurement but also to select the score for each item. Therefore, in the remote medical system in Patent Literature 2 also, the medical staff person as the measuring person, as ever, hesitates to determine selection of the score. Accordingly, in Patent Literature 2 also, it is impossible to resolve the problems of the hesitation in decision on the measurement (determination) and of the measurement time interval (determination time interval).
It is an object of the present invention to resolve the above-mentioned problems and to provide a patient status determination device, a patient status determination system, a patient status determination method, and a patient status determination program recording medium, which are capable of improving an operation of a medical staff person.
A patient status determination device according to the present invention comprises an indication unit configured to sequentially indicate, to a medical staff person, a plurality of items to be measured for a patient; a reaction recognition unit configured to recognize a reaction from the medical staff person to the indicated item to produce a recognized result; and a score determination unit configured to determine, based on the recognized result, a score for the indicated item to produce a determined score, wherein the indication unit is configured to present, to the medical staff person, each of the plurality of items in the form of at least one question associated with the item.
A patient status determination system according to the present invention comprises the patient status determination device described above and a totalization device configured to receive the determined score from the patient status determination device to totalize the score.
A patient status determination method according to the present invention comprises sequentially indicating, by an indication unit, to a medical staff person, a plurality of items to be measured for a patient; recognizing, by a reaction recognition unit, a reaction from the medical staff person to the indicated item to produce a recognized result; and determining, by a score determination unit, based on the recognized result, a score for the indicated item to produce a determined score, wherein the indication unit is configured to present, to the medical staff person, each of the plurality of items in the form of at least one question associated with the item.
A patient status determination program recording medium according to the present invention is a recording medium recording a patient status determination program which causes a computer to execute an indication step of sequentially indicating, to a medical staff person, a plurality of items to be measured for a patient; a reaction recognition step of recognizing a reaction from the medical staff person to the indicated item to produce a recognized result; and a score determination step of determining, based on the recognized result, a score for the indicated item to produce a determined score, wherein the indication step causes the computer to present, to the medical staff person, each of the plurality of items in the form of at least one question associated with the item.
According to the present invention, it is possible to improve an operation of a medical staff person.
Now, example embodiments of the present invention will be described in detail with reference to the drawings. Note that, in respective figures, the same or the corresponding parts are assigned with the same symbols and description of overlapping portions will be omitted as appropriate.
In the first example embodiment, the following case is supposed. In the illustrated patient status determination system, it is supposed that a medical staff person such as a nurse or a doctor measures (determines) a patient status in real time in every measurement period. In this case, the patient may be, for example, a patient emergently transported by an ambulance or the like. Such a patient is suspected to have a disorder such as a cerebrovascular disorder. The measurement period is, for example, fifteen minutes at the shortest. The patient status is, for example, paralysis, ataxia, and so on. In every measurement period, it is necessary for the medical staff person to perform a task of selecting, within a measurement time interval (determination time interval), a score for each of a plurality of items on the patient status. The plurality of items may be thirteen items which are defined by the above-mentioned NIHSS. The thirteen items defined by the NIHSS will later be described in detail with reference to the drawing. The measurement time interval (determination time interval) is desirably as short as possible as compared with the above-mentioned measurement period and is, for example, preferably three minutes.
The patient status determination device 100 is a device which can automatically determine the patient status in real time at a medical site. It is assumed that a patient ID (identifier) is assigned to the patient. Furthermore, a staff ID (user ID) may be assigned to the medical staff person.
The patient status determination device 100 comprises a data processing device 110 for processing data, a storage device 120 for storing a program and data, which will later be described, an input device 130 for inputting the data, an output device 140 for outputting the data, and a communication interface 150. Such a patient status determination device 100 may be implemented by, for example, a tablet PC (personal computer).
The output device 140 comprises a display device such as a LCD (Liquid Crystal Display) or a PDP (Plasma Display Panel), a printer, and a receiving set. The receiving set may be an earphone or a headphone. The output device 140 has a function of displaying, on a screen of the display device, a variety of information such as an operation menu and a plurality of questions associated with respective items, which will later be described, of informing each of the plurality of questions by a speech from the receiving set, and of printing a final result on the printer.
The storage device 120 is a storage medium which can hold a variety of data. For instance, the storage device 120 comprises the storage medium such as a HDD (Hard Disk Drive) or a SSD (Solid State Drive) or a memory such as a ROM (read only memory) and a RAM (random access memory). The storage device 120 has a function of storing a program 122 and processing information (which will later be described) required for a variety of processing in the data processing device 110.
The data processing device 110 comprises a microprocessor such as a MPU (micro processing unit) or a CPU (central processing unit). The data processing device 110 has a function of reading the program 122 from the storage device 120 to implement various processing units for processing the data in accordance with the program 122.
The input device 130 comprises, for example, a keyboard, a mouse, a touch panel, and a microphone. In addition, the input device 130 may comprise various sensors for measuring the patient status. Such sensors may be, for example, a wristwatch-type sensor and a vital sensor which are attached to the patient, and a camera for picking up the patient status, In this example embodiment, in a case where the input device 130 includes the touch panel and the output device 140 includes the display device, those devices may be integrally formed and configured as a display device with a touch panel.
The communication interface 150 is an interface for connecting the patient status determination device 100 and the totalization device 200, which will later be described, via a wire, wirelessly, or the like. The communication interface 150 is implemented, for example, by a transmitter, a transceiver, or a connector. In a case where the communication interface 150 comprises the transmitter, the transmitter modulates a carrier using a processed result (specifically, a determined score which will later be described) in the data processing device 110 and transmits a modulated wave as a transmitted wave to the totalization device 200 wirelessly. In a case where the communication interface 150 comprises the connector, a recording medium which is not shown in the figure may be used. In this event, the processed result (determined score) is written in the recording medium via the connector as recorded information with the patient ID added thereto.
In addition, the medical staff person may sometimes be required to perform a measure on the patient in question on measuring (determining) the patient status. Accordingly, it is desirable to use an earphone with a microphone or a headphone with a microphone as a combination of the above-mentioned receiving set and the above-mentioned microphone. Alternatively, the patient status determination device 100 may be kept on a transport table (bed) which carries the patient.
In this example embodiment, both of speeches and images (text data) are used as indications for the medical staff person and reactions of the medical staff person. Accordingly, the earphone with the microphone and the display device with the touch panel are provided as a combination of the input device 130 and the output device 140. However, in this invention, only the images (the text data) may be used as the indications for the medical staff person and the reactions of the medical staff person.
The storage device 120 comprises an item storage unit 124. In the item storage unit 124, a plurality of items required to measure the patient status within the above-mentioned measurement time interval (determination time interval) are preliminarily stored in a form of a plurality of questions associated with respective items in accordance with an order. In this example embodiment, the item storage unit 124 stores the plurality of questions as speech data and text data therein. For the plurality of items, allowed time intervals are preliminarily set, respectively, These allowed time intervals may be uniform or may be different from one another. In this example embodiment, the allowed time intervals are uniform. The allowed time intervals are stored in the item storage unit 124 in association with every item.
For example, such speech data and text data may be read out of a predetermined database and necessary information only may be preliminarily stored in the item storage unit 124 just before a starting time instant of the above-mentioned measurement time interval (determination time interval). Instead, in a case where the patient status determination device 100 is kept on the transport table (bed) of the patient, the following may be performed. First, from a control center which is not shown in the figure, a plurality of necessary items (speech data and text data) for the patient are read out of the predetermined database just before the starting time instant of the above-mentioned measurement time interval (determination time interval) and transmitted to the patient status determination device 100. The patient status determination device 100 may comprise a receiver (not shown) for receiving the transmitted necessary items and store the received necessary items in the item storage unit 124. In this example, the plurality of necessary items are preliminarily determined because those items are thirteen items defined by the above-mentioned NIHSS. Accordingly, instead, in the patient status determination device 100, the plurality of necessary items received by the receiver may be directly supplied to an indication unit 111 (which will later be described) of the data processing device 110 without using the item storage unit 124.
The data processing device 110 comprises, as main processing units, the indication unit 111, a reaction recognition unit 112, a score determination unit 113, a time measurement unit 114, and a control unit 118.
The indication unit 111 sequentially indicates, to the medical staff person, the plurality of items to be measured for the patient. The reaction recognition unit 112 recognizes a reaction from the medical staff person to the indicated item to produce a recognized result. The score determination unit 113 determines, based on the recognized result, a score for the indicated item to produce the determined score. The indication unit 111 presents, to the medical staff person, each of the plurality of items in the form of at least one question associated with the item. In this event, the indication unit 111 may present, to the medical staff person, the above-mentioned allowed time interval for every item. The time measurement unit 114 measures an elapsed time interval from the starting time instant when indication of each item to the medical staff person is started. The control unit 118 controls operation of the data processing device 110 as a whole. Hereinafter, operations of the respective processing units will be described more in detail.
The indication unit 111 sends the speech data read out of the item storage unit 124 to the earphone with the microphone of the output device 140. An earphone of the earphone with the microphone converts the speech data into a question speech. Accordingly, a combination of the indication unit 111 and the earphone of the output device 140 serves as a speech notification means for sequentially notifying the medical staff person of the plurality of items with the question speeches. In addition, a combination of the item storage unit 124, the indication unit 111, and the earphone of the output device 140 acts as a presentation unit for sequentially presenting, to the medical staff person, the plurality of necessary items required to measure the patient status with speeches.
Simultaneously, the indication unit 111 sends the text data read out of the item storage unit 124 to the display device with the touch panel of the output device 140. The display device with the touch panel displays the text data on a display screen thereof. Accordingly, a combination of the indication unit 111 and the display device with the touch panel of the output device 140 serves also as a text notification means for sequentially notifying the medical staff person of the plurality of items as question text data. Thus, a combination of the item storage unit 124, the indication unit 111, and the display device with the touch panel of the output device 140 acts as a presentation unit for sequentially presenting, to the medical staff person, the plurality of necessary items required to measure the patient status with the images (text data).
In response to the question speech generated from the earphone of the earphone with microphone of the output device 140, the medial staff person utters an answer (response) corresponding thereto towards the microphone of the earphone with the microphone of the input device 130. For example, it is assumed that “is there a reaction?” as the question speech flows from the earphone. In this event, the medical staff person answers (responds), for example, “yes” with a speech towards the microphone. The microphone converts an answer speech of “yes” into an input value of an answer speech signal which is an electric signal. Accordingly, the microphone of the earphone with the microphone serves as an input unit configured to input the answer speech uttered by the medical staff person in response to the indicated item, and to output the input value answer speech signal).
Simultaneously, in response to the question text data displayed on the display device with touch panel of the output device 140, the medical staff person operates the touch panel of the display device with touch panel as the input device 130 to input an answer (response) corresponding thereto. Herein, it is assumed that icons of “Yes” and “No” are displayed on the touch panel with touch panel. For example, it is assumed that the question text data displayed on the display device with touch panel is “it there a reaction?” In this event, the medical staff person answers (responds), for example, by touching the icon of “Yes” of the touch panel. The touch panel produces an answer text signal indicative of the answer of “Yes.” Accordingly, the touch panel of the display device with touch panel serves as an input unit configured to input the answer text signal by the medical staff person in response to the indicated item.
As described above, in this example embodiment, both of the speech and the image (text data) are used as the reaction from the medical staff person. However, in a noisy environment or the like, there is a case where only the image (text data) can be used as the reaction to the question. In this case, of course, only the image (text data) is used as the reaction from the medical staff person.
It is assumed that the input device 130 supplies the reaction recognition unit 112 with the answer speech signal uttered from the medical staff person as the reaction. The reaction recognition unit 112 includes a speech recognition unit (not shown). The speech recognition unit identifies the answer speech signal to produce an identified result as the above-mentioned recognized result. For instance, it is assumed that the answer speech signal is a speech signal indicative of “yes.” In this event, the speech recognition unit of the reaction recognition unit 112 produces a result of “Yes” as the recognized result (identified result).
On the other hand, it is assumed that the input device 130 supplies the reaction recognition unit 112 with the answer signal obtained by operation (touching) of the medical staff person as the reaction. In this event, the reaction recognition unit 112 recognizes the answer text signal to produce the recognized result. For instance, it is assumed that the answer text signal is a text signal indicative of “Yes,” In this event, the reaction recognition unit 112 produces a result of “Yes” as the recognized result.
The recognized result is supplied to the score determination unit 113. The score determination unit 113 determines, based on the recognized result, the score for the indicated item. For instance, it is assumed that the indicated item is “Level of Consciousness.” In this event, the indication unit 11 provides, to the medical staff person via the output device 140, an indication of “Is there a reaction?” together with an indication (guidance) of a measure for the patient. In response to the indication of “Is there a reaction?”, the score determination unit 113 is supplied from the reaction recognition unit 112 with the recognized result of “Yes” or “No.” The score determination unit 113 determines, based on the recognized result of “Yes” or “No”, the score (in this case, a score between 0 and 3) for the item of “Level of Consciousness.”
The totalization device 200 comprises a data processing device 210 for processing data, a storage device 220 for storing a program and data which will later be descried, and a communication interface 230. The data processing device 210 includes a totalization unit 212.
The communication interface 230 is an interface for connecting the totalization device 200 and the patient status determination device 100 described above via a wire, wirelessly, or the like. The communication interface 230 is implemented, for example, by a receiver, a transceiver, or a connector. In a case where the communication interface 230 comprises the receiver, the receiver receives, as a received wave, the transmitted wave which is transmitted from the communication interface (transmitter) 150 of the patient status determination device 100. The receiver demodulates the received wave to reproduce the above-mentioned processed result (determined score). In a case where the communication interface 230 comprises the connector, the recorded information (determined score and patient ID) recorded in the recording medium is read therefrom via the connector.
From the communication interface 230, the reproduced (read-out) determined score is supplied to the data processing device 210. The totalization unit 212 of the data processing device 210 totalizer the score. The totalization unit 212 stores a totalized result in the storage unit 220.
Now, effects of the first example embodiment will be described, As described above, the patient status determination device 100 according to the first example embodiment can appropriately determine the patient status by the medical staff person in a relatively short measurement time interval (determination time interval) without hesitation in scoring. This is because appropriate guidance and indication are provided for the medical staff person.
[Operation of Patient Status Determination Device]
First, the indication unit 111 reads an item out of the item storage unit 124 to cause the receiving set and the display device of the output device 140 to present guidance of the item (Step S101). In this event, the indication unit 111 may cause the display device to present, on the display screen thereof, an allowed time interval set for the item. Simultaneously, the control unit 118 starts the time measurement unit 114 to cause the time measurement unit 114 to measure an elapsed time interval from a starting time instant when such indication is started.
Subsequently, the indication unit 111 uses the earphone and the display device of the output device 140 to present a question of the item as a question speech and question text data (Step S102).
In response to the question speech and the question text data, the medical staff person utters an answer speech from the microphone of the input device 130 or inputs an answer by operating the touch panel of the input device 130. The reaction recognition unit 112 recognizes (confirms) the answer speech signal or the answer text signal to produce a recognized result (confirmed result) (Step S103).
The control unit 118 determines whether or not the elapsed time interval measured by the time measurement unit 114 exceeds the above-mentioned allowed time interval (Step S104). When the elapsed time interval does not exceed the allowed time interval (No in Step S104), the control unit 118 determines whether or not the question is the last question in the item (Step S105). If it is not the last question (No in Step S105), the control unit 118 causes the indication unit 111 to present the next question (Step S102). If it is the last question (Yes in Step S105), the score determination unit 113 determines a score for the item based on the recognized result(s) up to then and the control unit 118 controls the indication unit 111 to shift to the next item (Step S106).
When the elapsed time interval measured by the time measurement unit 114 exceeds the allowed time interval (Yes in Step S014), the score determination unit 113 selects and produces, as a determined score, a higher score as a reaction to the question at that time instant (Step S107) and the control unit 118 controls the indication unit 111 to shift to the next item (Step S106).
The patient status determination device 100A is similar in structure and operation to the patient status determination device 100 illustrated in
The data processing device 110A carries out processing operations similar to those of the data processing device 110 illustrated in
The score and time recording unit 126 records, as recorded information, the determined score determined by the score determination unit 113 and the elapsed time interval at the time measurement unit 114 in association with the indicated item. In other words, the control unit 118A causes the score and time recording unit 126 to store, as the recorded information, the determined score determined by the score determination unit 113 and the elapsed time interval at the time measurement unit 114 in association with the indicated item. In addition, the staff ID (user ID) may also be recorded as the recorded information.
The indication unit 111A changes, based on the recorded information recorded in the score and time recording unit 126 during past measurements including at least the last time, notification contents to be indicated to the medical staff person in a current measurement. The changed notification contents include the allowed time interval which is set for the indicated item. That is, in the second example embodiment, the allowed time interval is adjusted for each item. In addition, as the changed notification contents, the display device with touch panel of the output device 140 may display the score given to the item in the past in combination with the question. In this event, the medical staff person can react with reference to the displayed contents also. As a result, it is possible to shorten the measurement time interval (determination time interval) and to carry out appropriate scoring.
Now, effects of the second example embodiment will be described. The patient status determination device 100A according to the second example embodiment can carry out appropriate determination with the measurement time interval (determination time interval) shortened as compared with the case of the above-mentioned first example embodiment. This is because the indication unit 111A carries out appropriate guidance and indication for the medical staff person by feeding back the measured results in the past.
The patient status determination device 100B is similar in structure and operation to the patient status determination device 100A illustrated in
The data processing device 110B carries out processing operations similar to those of the data processing device 110A illustrated in
Although not-illustrated in the figure, as described above, the wristwatch-type sensor and the vital sensor are attached to the patient and the camera for picking up the patient is equipped in the transport table (bed) for transporting the patient or in a sick room for accommodating the patient. The measurement state recording unit 128 records, as a measurement state, data acquired from those sensors and an image picked-up by the camera. In other words, the control unit 118B causes the measurement state recording unit 128 to store, as the measurement state, the vital data acquired from those sensors and the image picked-up by the camera.
The indication unit 111B changes, based on the recorded information recorded in the score and time recording unit 126 and the measurement state recorded in the measurement state recording unit 128 during past measurements including at least the last time, notification contents to be indicated to the medical staff person in a current measurement. The changed notification contents include the allowed time interval which is set for the indicated item, like in the above-mentioned second example embodiment. That is, in the third example embodiment also, the allowed time interval is adjusted for each item. In addition, as the changed notification contents, the display device with touch panel of the output device 140 may display the score given to the item in the past, the vital data, and the image of the patient in combination with the question. In this event, the medical staff person can react with reference to these displayed contents also. As a result, it is possible to furthermore shorten the measurement time interval (determination time interval) and to carry out more appropriate scoring.
Now, effects of the third example embodiment will be described, The patient status determination device 100B according to the third example embodiment can carry out more appropriate determination with the measurement time interval (determination time interval) furthermore shortened as compared with the case of the above-mentioned second example embodiment. This is because the indication unit 111B carries out appropriate guidance and indication for the medical staff person by feeding back the measured results in the past and the condition of the patient.
[Operation of Patient Status Determination Device]
Operations in Steps S101 to S106 of
It is assumed that determination of a score by the score determination unit 112 finishes after the last question (Yes in Step S105) or that selection of the score by the score determination unit 112 (Step S107) finishes after the elapsed time interval at the time measurement unit 114 exceeds the allowed time interval (Yes in Step S104). Thereafter, the control unit 118B causes the score and time recording unit 126 to store, as the recorded information, the score determined by the score determination unit 113 and the elapsed time interval at the time measurement unit 114 in association with the indicated item (Step S108).
Subsequently, the control unit 118B causes the measurement state recording unit 128 to store, as the measurement state, the vital data acquired from the above-mentioned sensors and the image picked-up by the camera (Step S109). Thereafter, the control unit 118B controls the indication unit 11B to shift to the next item (Step S106).
Now, referring to
First, the control unit 118B confirms the user ID (staff ID) (Step S201). Subsequently, the control unit 118B reads the recorded information and the measurement state out of the score and time recording unit 126 and the measurement state recording unit 128, respectively, to confirm a recorded state of the patient until now (Step S202). The control unit 118B adjusts, based on the recorded state, the allowed time interval which is set for each item (Step S203). Thereafter, the control unit 118B starts the above-mentioned sensors and the cameral to start recording of measurement states (Step S204). Then, the control unit 118B controls the indication unit 111B to start the measurement from the first item (Step S205).
The patient status determination device 100C is similar in structure and operation to the patient status determination device 100A illustrated in
The data processing device 110C carries out processing operations similar to those of the data processing device 110A illustrated in
The patient status determination device 100C is communicably connected to an analogous case database which is not shown in the figure. The analogous case database is a database which preliminarily saves a plurality of analogous cases.
In a case where the reaction cannot be obtained from the medical staff person at a time instant when the elapsed time interval measured by the time measurement unit 114 exceeds the above-mentioned allowed time interval, the analogous case extraction unit 115 extracts, from the analogous case database, an analogous case which is analogous to a status of the patient and presents the extracted analogous case to the medical staff person.
Now, effects of the fourth example embodiment will be described. The patient status determination device 100C according to the fourth example embodiment can carry out more appropriate determination, as compared with the above-mentioned second example embodiment. This is because the analogous case in the past is presented to the medical staff person.
[Operation of Patient Status Determination Device]
Operations in Steps S101 to S106 of
When the elapsed time interval measured by the time measurement unit 114 exceeds the allowed time interval (Yes in Step S104), the analogous case extraction unit 115 extracts, from the analogous case database, an analogous case which is analogous to a status of the patient in question and presents the extracted analogous case by displaying it on the display device with touch panel of the output device 140 (Step S110). Accordingly, the medical staff person can react with reference to the displayed analogous case. The reaction recognition unit 112 recognizes the reaction from the medical staff person to produce a recognized result (Step S111). The score determination unit 113 determines a score for the specified item based on the recognized result and the control unit 118C controls the indication unit 111A to shift to the next item (Step S106).
Now, referring to

Like in this example, in a case where the item is a specific item such as “Facial Palsy”, the indication unit 111 first indicates, as a first one of a plurality of questions for the specific item, a question for which the medical staff person can easily judge the status of the patient (in this example, “Is there no paralysis?”). Then, the indication unit 111 indicates, as a last one of the plurality of questions for the specific item, a question for which the medical staff person hardly judge the status of the patient (in this example, “Is a half or more of the face of the patient paralyzed?”).
By selecting the order of the questions to be presented in this manner, more accurate scoring is possible in this example. In detail, if the questions are not made in such an order, the medical staff person observes the face of the patient and must judge, by him/herself, whether or not there is any paralysis and, in presence of the paralysis, the level of the paralysis. Such judgment is very difficult and, therefore, the medical staff person (especially, an unexperienced medical staff person) may frequently hesitate in judgement. As a result, under the above-mentioned circumstances, the medical staff person may frequently select either the lowest score of zero or the highest score of three. This results in a large error in score. In contrast, in this example, a question which is easy to judge is first asked and a question which is hard to judge is asked last, so that more accurate scoring is possible.

The patient status determination devices 100 to 100C mentioned above may be implemented by hardware or may be implemented by software. Alternatively, the patient status determination devices 100 to 100C may be implemented by a combination of hardware and software.
It is noted that the program 122, which is readable by the data processing devices 110 to 110C, may be supplied to the patient status determination devices 100 to 100C in a state where it is non-transitorily stored in various types of recording media which is readable by a computer. Such recording media include, for example, a magnetic tape, a magnetic disk, a magneto-optical disc, a CD-ROM (Compact Disc-Read Only Memory), a CD-R (Compact Disc-Readable), a CD-RW (Compact Disc-ReWritable), and a semiconductor memory.
While the present invention has been described with reference to the example embodiments and the example thereof, the present invention is not limited thereto. For example, the present invention includes modes obtained by appropriately combining a part or a whole of the example embodiments and the example described so far or a mode obtained by appropriately modifying those modes.
For example, although the data processing device comprises the time measurement unit in any of the above-mentioned example embodiments, it may be omitted in the present invention, In this case, although the problem of the measurement time interval (determination time interval) may remain, it is possible to resolve the problem of the hesitation in decision on measurement (determination) of scoring. This is because the appropriate guidance and indication are given to the medical staff person.
In addition, a “help” button may be displayed on the display screen of the display device with touch panel. In this case, for example, when an unexperienced medical staff person pushes the “help” button, the “determined score” for an analogues patient in the past, that is scored by a skilled medical staff person in the past, is displayed on the display screen in association with the indicated item. Thus, the unexperienced medical staff person can perform appropriate scoring with reference to the displayed contents.
Furthermore, although the totalization device 200 merely receives the determined score from the patient status determination device and totalizes the score in the above-mentioned example embodiments, the present invention is not limited thereto. That is, the present invention may be applied to an electronic medical chart system comprising a medical recording database in lieu of the totalization device 200.
In this case, each of the patient status determination devices 100A to 100C wirelessly transmits, to the electronic medical chart system via the communication interface 150, the recorded information (indicated item, determined score, and elapsed time interval) recorded in the score and time recording unit 126 of the storage device 120A or 120B in association with the patient ID. The electronic medical chart system records (transcribes) the received recorded information (which is associated with the patient ID) together with the totalized result in a corresponding field of the patient ID on the medical recording database.
Furthermore, when the communication interface 150 comprises the connector, each of the patient status determination devices 100A to 100C writes, in an outside recording medium via the connector, the recorded information (indicated item, determined score, and elapsed time interval) recorded in the score and time recording unit 126 of the storage device 120A or 120B in association with the patient ID. Then, the electronic medical chart system reads the recorded information recorded in the outside recording medium via a connector provided in the electronic medical chart system, and records (transcribes) the read information, together with the totalized result, in the corresponding field of the patient ID on the medical recording database.
