[Technical Field]
[0001] The present invention relates to a monitoring system, a wearable terminal, a monitoring method, and a program. [Background technology]
[0002] Patent Document 1 describes a monitoring system that includes a wearable device and a management server. In the technology described in Patent Document 1, the wearable device is worn by the person being monitored, such as an elderly person, and a biosensor in the wearable device measures biometric data such as the heartbeat pattern and heart rate of the person being monitored. However, the technology described in Patent Document 1 measures the biological data of the person being watched over (the person wearing the wearable device), but does not perform monitoring that takes into account whether the person wearing the wearable device has impaired consciousness. Therefore, the technology described in Patent Document 1 may not be able to appropriately monitor the person wearing the wearable device. On the other hand, if the alert for evaluating consciousness disorder used to evaluate the consciousness disorder of the wearable device wearer is output more than necessary, the wearer of the wearable device may find the alert for evaluating consciousness disorder annoying. Furthermore, if the evaluation of the consciousness disorder of the wearable device wearer is performed more than necessary, the accuracy of the evaluation of the consciousness disorder of the wearable device wearer may decrease.

DETAILED DESCRIPTION OF THE INVENTION
[0011] Before describing the embodiments of the monitoring system, wearable terminal, monitoring method, and program of the present invention, the background to the use of wearable terminals will be described.
[0012] A wearable device is a device that is worn on the body. Common types of wearable devices include wristwatch-type wearable devices, eyeglass-type wearable devices, and camera-type wearable devices. Wristwatch-type wearable devices include "watch-type" and "wristband-type." "Watch-type" wristwatch-type wearable devices are a type of device called a "smartwatch," and by connecting to a smartphone, you can check emails, social media, and other incoming messages without having to take out the smartphone. "Wristband-type" wristwatch-type wearable devices are wearable devices in the shape of a wristband, and are primarily used as activity trackers for recording daily activities and health management. Wearable devices can be used to record or measure daily activity data such as weight, blood pressure, heart rate, number of steps taken, calories burned, sleep quality, dietary content, etc. Wearable devices are expected to be useful for monitoring health conditions and for the early detection and prevention of serious diseases.
[0013] Wearable devices capable of measuring superficial wrist temperature, heart rate, blood pressure, and blood oxygen saturation are already available on the market. For example, Apple's Apple Watch® Series 7 comes equipped with an electrocardiogram app and a blood oxygen wellness app. Furthermore, on January 5, 2021, Apple obtained a patent from the United States Patent and Trademark Office (USPTO) for a device that can measure blood pressure using the Apple Watch alone, without the use of a cuff. https: / / iphone-mania.jp / news-338090 / The Wall Street Journal also reported that the Apple Watch could be equipped with a temperature measurement feature as early as 2022. https: / / iphone-mania.jp / news-394813 /
[0014] As for wearable devices capable of measuring body temperature, Pham et al. developed a wearable device that estimates core body temperature by integrating heart rate, SpO2, physical activity level, skin temperature, and galvanic skin response. https: / / www.mdpi.com / 1424-8220 / 20 / 3 / 855 Lin has also developed a wearable device that can measure body temperature in actual runners. https: / / www.mdpi.com / 1424-8220 / 18 / 12 / 4347 The estimated temperature by Pham et al. reflects core body temperature rather than skin temperature, but the estimated values by Lin et al. do not compare with skin temperature. Furthermore, both methods only provide experimental data for 36-37°C, making it unclear whether they accurately reflect data for temperatures around 40°C, the temperature at which heatstroke occurs. Furthermore, the device by Pham et al. uses a cuff wrapped around the upper arm, while the device by Lin et al. requires devices to be worn on the wrist and elbow, making both difficult to apply to actual sports or work. At present, no wearable device capable of measuring core body temperature has been developed that can be applied to actual sports or work.
[0015] In the Glasgow Coma Scale (GCS) and the Japan Coma Scale (JCS), responses to calls and pain stimuli are used to assess the level of consciousness. https: / / www.kango-roo.com / learning / 3121 / https: / / www.kango-roo.com / learning / 3082 / The Apple Watch Series 7 has a fall detection function during workouts, which uses the built-in accelerometer to detect unusual movements and impacts, such as falling while riding a bicycle or standing. If the built-in accelerometer were to determine that a lack of movement was an indication of impaired consciousness, then simple sleep would also be mistakenly determined to be impaired consciousness, so it can be said that the level of consciousness cannot currently be monitored with a smartwatch.
[0016] In hospital intensive care units, chest movement is monitored to measure respiratory rate, but smartwatches cannot monitor chest movement, and it is also difficult to monitor blood tests using smartwatches.
[0017] With the progress of global warming and the increase in heat waves, heatstroke has become a serious public health issue. Despite prevention efforts by national and local governments and media outlets, 71,317 people nationwide were taken to the hospital by ambulance due to heatstroke in August 2020 (an increase of 6,305 from the same month last year). In addition to public relations and media awareness-raising based on Wet Bulb Globe Temperature (WBGT: an index proposed in the United States in 1954 for the purpose of preventing heatstroke), further prevention efforts are considered necessary. https: / / www.wbgt.env.go.jp / wbgt.php
[0018] Overseas, it is common to follow the Bouchama criteria outlined in a 2002 review in N Engl J Med: https: / / www.nejm.org / doi / full / 10.1056 / nejmra011089 Severe heat stroke is defined as a deep body temperature of 40°C or higher accompanied by central nervous system damage. Heat exhaustion is a mild to moderate condition with a variety of symptoms, and is described as often having a deep body temperature of 37-40°C. A notable feature of the Bouchama criteria is that deep body temperature plays a major role in determining the severity of the condition. In the following literature, the inventors have demonstrated through multivariate analysis using various prognostic predictors that the absence of active cooling in heat stroke increases the in-hospital mortality rate, while the administration of intravenous drip alone does not change the in-hospital mortality rate in heat exhaustion. Kanda J, Nakahara S, Nakamura S, et al. “Association between active cooling and lower mortality among patients with heat stroke and heat exhaustion”. PLoS One. 2021; 16 (11): e0259441. https: / / pubmed.ncbi.nlm.nih.gov / 34788312 / The Bouchama criteria are global standards with clear evidence, but they require monitoring of core body temperature and loss of consciousness, which cannot be measured with current wearable devices.
[0019] In Japan, the "2015 Heatstroke Classification of the Japanese Society of Acute Medicine" is used as the standard diagnostic criteria for the severity of heatstroke. https: / / www.kango-roo.com / work / 1539 / The 2015 Japanese Society for Acute Medicine Classification of Heatstroke classifies heatstrokes into stages I to III based on clinical symptoms. The most severe stage III symptoms include loss of consciousness, liver and kidney damage, and blood clotting abnormalities (DIC: Disseminated Intravascular Coagulation), and correspond to heat stroke. Stage I symptoms include dizziness, excessive sweating, absence of consciousness, muscle pain, and cramps, and correspond to heat syncope and heat cramp. Stage II symptoms include headache, vomiting, fatigue, weakness, and impaired concentration and judgment (JCS score of 1 or less), and correspond to heat exhaustion. A distinctive feature of Japan's severity classification is that for severe cases, blood tests are used to determine the severity of multiple organ failure. Even for mild cases, a doctor must diagnose specific symptoms to determine the severity. The 2015 Heatstroke Classification of the Japanese Society of Acute Medicine is the most commonly used assessment method in Japan, but because it requires an assessment of impaired consciousness and blood tests to determine the severity, and because a doctor's specific diagnosis is required even for mild cases, it could not be applied to wearable devices.
[0020] The J-ERATO score is composed of six items (respiratory rate, loss of consciousness, systolic blood pressure, heart rate, body temperature, and age) measured before arrival at the hospital, each of which is given a score of 0 or 1, for a total score ranging from 0 to 6. https: / / medit.tech / j-erato-score-app-released-2021 / The J-ERATO score was calculated based on data from approximately 3,000 patients in the Heatstroke Study 2010 and 2012 conducted by the Japanese Society of Acute Medicine, and does not take into account the treatment provided after hospitalization. However, the evaluation items are hospitalization (listed as "hospitalization rate"), admission to the intensive care unit (ICU) (listed as "ICU admission rate"), and in-hospital mortality rate (listed as "mortality rate"). The Japanese Society of Acute Medicine also created a "heatstroke diagnosis support application for smartphones" based on the J-ERATO score. The application provides first aid instructions and displays maps and directions to nearby hospitals, but there was no system in place to prevent heatstroke by measuring the six J-ERATO score items in real time. Conventional wearable devices were unable to monitor the six items in the J-ERATO score: loss of consciousness and respiratory rate.
[0021] Mimamori Fukurou, a labor / heatstroke management service from Sompo Holdings, uses AI to analyze workers' pulse rates and location information in real time. https: / / www.sompo-rc.co.jp / services_mimamorifukuro The website indicated by the URL above does not make clear the AI's diagnostic process, but it appears that of the six items in the J-ERATO score, only heart rate is extracted.
[0022] Some wearable devices are unable to measure the core body temperature of the wearer, so in order for the wearable device to properly monitor the wearer, other indicators must be used in place of core body temperature. The Bouchama criteria, the 2015 Heatstroke Classification of the Japanese Association for Acute Medicine, and the J-ERATO score all use the degree of loss of consciousness as an evaluation item for severity. Therefore, in order to properly monitor the wearer of a wearable device using a wearable device, it is necessary to monitor the wearer's loss of consciousness. The wearable device can measure the wearer's superficial body temperature, heart rate, mean blood pressure, and blood oxygen saturation (SpO2). The APACHE (acute physiology and chronic health evaluation) II score is a prognostic prediction method developed to objectively evaluate the severity of patients admitted to intensive care units, and is used in many facilities in Japan. The APACHE II score calculates predicted mortality rates based on 12 indices of respiration, circulation, blood test values, and GCS, as well as age and chronic disease scores. https: / / www.fmu.ac.jp / home / masui / anesthesiologists / apache.html
[0023] In an intensive study, the inventor has discovered that a wearable device outputs an alert for evaluating consciousness disorder used to evaluate the consciousness disorder of the wearer of the wearable device (for example, sound, vibration, a weak current that causes pain to the wearer of the wearable device, etc.), and detects the reaction of the wearer of the wearable device (for example, by detecting an input operation by the wearer of the wearable device to an operation unit of the wearable device, or by detecting an action of the wearer shaking the wearable device by the wearer of the wearable device using an acceleration sensor of the wearable device, etc.), thereby determining the reaction of the wearer of the wearable device to the alert for evaluating consciousness disorder. We found that responses could be classified into one of the following JCS scores: "0: conscious," "1: oriented but not conscious," "2: disoriented," "3: unable to state own name or date of birth," "10: opens eyes when called upon normally," "20: opens eyes when called upon loudly or shaken vigorously," "30: barely opens eyes when called upon while painful stimuli are applied," "100: makes movements such as brushing away pain," "200: moves limbs or grimaces when painful stimuli are applied," and "300: does not respond at all to painful stimuli." On the other hand, if the alert for evaluating consciousness disorder used to evaluate the consciousness disorder of the wearable device wearer is output more than necessary, the wearer of the wearable device may find the alert for evaluating consciousness disorder annoying. Furthermore, if the evaluation of the consciousness disorder of the wearable device wearer is performed more than necessary, the accuracy of the evaluation of the consciousness disorder of the wearable device wearer may decrease. In view of the above-mentioned problems, in the embodiments of the monitoring system, wearable device, monitoring method and program of the present invention described below, the output of alerts for assessing impaired consciousness is kept to a minimum, and when necessary, the wearer of the wearable device is appropriately monitored based on a severity assessment score that includes an assessment of impaired consciousness.
[0024] [First embodiment] Hereinafter, embodiments of the monitoring system, the wearable terminal, the monitoring method, and the program of the present invention will be described. FIG. 1 is a diagram showing an example of a monitoring system 1 according to a first embodiment. The monitoring system 1 according to the first embodiment monitors a person wearing a wearable device 1A. Specifically, the monitoring system 1 according to the first embodiment monitors the severity of heatstroke in the person wearing the wearable device 1A. In other words, the monitoring system 1 according to the first embodiment is used to prevent the occurrence of heatstroke or the aggravation of heatstroke in the person wearing the wearable device 1A. In the example shown in FIG. 1, the monitoring system 1 includes a wearable device 1A and a management server 1B. The wearable device 1A and the management server 1B are configured to be able to communicate with each other via, for example, a network. The wearable device 1A is worn by a subject to be monitored by the monitoring system 1 of the first embodiment. The wearable device 1A is, for example, a "watch type" or "wristband type" device.
[0025] In the example shown in FIG. 1, wearable device 1A includes input unit 1A1, detection unit 1A2, score calculation unit 1A3, alert output unit 1A4, and transmission unit 1A5. Input unit 1A1 accepts an input operation for inputting the age of the wearer of wearable terminal 1A. The detector 1A2 detects biological information of the wearer of the wearable terminal 1A. The detection unit 1A2 includes a superficial body temperature detection unit 1A21, a heart rate detection unit 1A22, a blood pressure detection unit 1A23, a blood oxygen concentration saturation detection unit 1A24, and a reaction detection unit 1A25. The superficial body temperature detection unit 1A21 detects the superficial body temperature of the person wearing the wearable device 1A. The superficial body temperature detection unit 1A21 detects the superficial body temperature of the person wearing the wearable device 1A by using, for example, the technology described on page 20 of the website indicated by the following URL: https: / / www.soumu.go.jp / ict_skill / pdf / ict_skill_1_2.pdf
[0026] The heart rate detector 1A22 detects the heart rate of the person wearing the wearable device 1A. The heart rate detector 1A22 detects the heart rate of the person wearing the wearable device 1A by using, for example, the technology described on pages 19 and 20 of the website indicated by the above URL. The blood pressure detection unit 1A23 detects the mean blood pressure of the person wearing the wearable terminal 1A. The blood pressure detection unit 1A23 detects the mean blood pressure of the person wearing the wearable terminal 1A by using, for example, the technology described on the website indicated by the following URL: https: / / rentry.jp / note / blood-pressure-smart-watch /
[0027] The blood oxygen concentration saturation detection unit 1A24 detects the blood oxygen concentration saturation of the person wearing the wearable device 1A. The blood oxygen concentration saturation detection unit 1A24 detects the blood oxygen concentration saturation of the person wearing the wearable device 1A by using, for example, the technology described on the website indicated by the following URL: https: / / news.mynavi.jp / article / 20150206-oximeter / https: / / www.sankei.com / article / 20201212-TQI2DCH7XBM35EJV6LPXLOP6ZU / https: / / wired.jp / 2020 / 12 / 06 / how-to-use-blood-oxygen-data-on-apple-watch-garmin-fitbit-samsung / https: / / www.watch.impress.co.jp / docs / review / minireview / 1322495.html https: / / monoist.atmarkit.co.jp / mn / articles / 2010 / 13 / news008.html
[0028] Response detection unit 1A25 detects a response of the wearer of wearable terminal 1A to the alert for consciousness disorder evaluation output by alert output unit 1A4 (for example, sound, vibration, or a weak current that causes pain to the wearer of the wearable terminal, etc.). Response detection unit 1A25 detects a response of the wearer of wearable terminal 1A to the alert for consciousness disorder evaluation output by alert output unit 1A4, for example, by detecting an input operation by the wearer of wearable terminal 1A to an operation unit (not shown) of wearable terminal 1A, or by detecting an action of the wearer of wearable terminal 1A shaking wearable terminal 1A using an acceleration sensor (not shown) of wearable terminal 1A. In other words, the information of the wearer of the wearable terminal 1A detected by the detection unit 1A2 includes biometric information of the wearer of the wearable terminal 1A, such as the superficial body temperature of the wearer of the wearable terminal 1A, the heart rate of the wearer of the wearable terminal 1A, the mean blood pressure of the wearer of the wearable terminal 1A, and the blood oxygen concentration saturation of the wearer of the wearable terminal 1A, as well as the response of the wearer of the wearable terminal 1A to the alert for evaluating impaired consciousness output by the alert output unit 1A4.
[0029] The score calculation unit 1A3 calculates a severity evaluation score used to evaluate the severity of the wearer of the wearable terminal 1A, based on the biological information of the wearer of the wearable terminal 1A detected by the detection unit 1A2, etc. The score calculation unit 1A3 includes a pre-alert score calculation unit 1A31 and a post-alert score calculation unit 1A32. Pre-alert score calculation unit 1A31 calculates a severity evaluation score that does not include an evaluation of impaired consciousness. In detail, pre-alert score calculation unit 1A31 calculates a severity evaluation score that does not include an evaluation of impaired consciousness based on the age of the wearer of wearable device 1A received by input unit 1A1, the superficial body temperature of the wearer of wearable device 1A detected by superficial body temperature detection unit 1A21, the heart rate of the wearer of wearable device 1A detected by heart rate detection unit 1A22, the mean blood pressure of the wearer of wearable device 1A detected by blood pressure detection unit 1A23, and the blood oxygen concentration saturation of the wearer of wearable device 1A detected by blood pressure detection unit 1A24 (that is, based on biological information of the wearer of wearable device 1A). Post-alert score calculation unit 1A32 calculates a severity evaluation score including an evaluation of a disorder of consciousness. In detail, post-alert score calculation unit 1A32 calculates a severity evaluation score including an evaluation of a disorder of consciousness based on the age of the wearer of wearable terminal 1A received by input unit 1A1, the superficial body temperature of the wearer of wearable terminal 1A detected by superficial body temperature detection unit 1A21, the heart rate of the wearer of wearable terminal 1A detected by heart rate detection unit 1A22, the mean blood pressure of the wearer of wearable terminal 1A detected by blood pressure detection unit 1A23, the blood oxygen concentration saturation of the wearer of wearable terminal 1A detected by blood oxygen concentration saturation detection unit 1A24, and the response of the wearer of wearable terminal 1A to the alert for evaluating a disorder of consciousness detected by response detection unit 1A25 (that is, based on the biological information of the wearer of wearable terminal 1A and the response of the wearer of wearable terminal 1A to the alert for evaluating a disorder of consciousness).
[0030] The alert output unit 1A4 outputs an alert for evaluating consciousness disorder used to evaluate consciousness disorder of the wearer of the wearable terminal 1A (for example, sound, vibration, or a weak current that causes pain to the wearer of the wearable terminal 1A). Transmission unit 1A5 transmits the severity evaluation score calculated by score calculation unit 1A3 to management server 1B. That is, transmission unit 1A5 transmits the severity evaluation score that does not include the evaluation of consciousness disorder calculated by pre-alert score calculation unit 1A31 of score calculation unit 1A3, and the severity evaluation score that includes the evaluation of consciousness disorder calculated by post-alert score calculation unit 1A32 of score calculation unit 1A3, to management server 1B. In addition, the transmission unit 1A5 transmits to the management server 1B the superficial body temperature, heart rate, mean blood pressure, and blood oxygen saturation level (biometric information of the wearer of the wearable terminal 1A) of the wearer of the wearable terminal 1A used in calculating the severity assessment score that does not include an assessment of impaired consciousness. Furthermore, the transmission unit 1A5 transmits to the management server 1B the superficial body temperature, heart rate, mean blood pressure, and blood oxygen saturation level (biometric information of the wearer of the wearable terminal 1A) of the wearer of the wearable terminal 1A used to calculate the severity assessment score including the assessment of consciousness disorder, as well as the response of the wearer of the wearable terminal 1A to the alert for assessing consciousness disorder.
[0031] The management server 1B comprises a receiving unit 1B1 and an output unit 1B2. The receiving unit 1B1 receives the severity assessment score not including an assessment of impaired consciousness transmitted by the transmitting unit 1A5 of the wearable terminal 1A, the biometric information of the wearer of the wearable terminal 1A used to calculate the severity assessment score not including an assessment of impaired consciousness, the severity assessment score including an assessment of impaired consciousness, and the biometric information of the wearer of the wearable terminal 1A used to calculate the severity assessment score including an assessment of impaired consciousness, and the response of the wearer of the wearable terminal 1A to the alert for assessing impaired consciousness. The output unit 1B2 outputs the severity assessment score not including an evaluation of impaired consciousness received by the receiving unit 1B1, the biometric information of the wearer of the wearable terminal 1A used to calculate the severity assessment score not including an evaluation of impaired consciousness, the severity assessment score including an evaluation of impaired consciousness, and the biometric information of the wearer of the wearable terminal 1A used to calculate the severity assessment score including an evaluation of impaired consciousness, and the response of the wearer of the wearable terminal 1A to the alert for evaluating impaired consciousness. Therefore, the user of management server 1B (the person who manages the wearer of wearable terminal 1A) can check the severity of heatstroke of the wearer of wearable terminal 1A by checking the output from output unit 1B2.
[0032] FIG. 2 is a diagram for explaining an example of the severity evaluation score calculated by the score calculation unit 1A3. In the example shown in FIG. 2, score calculation unit 1A3 calculates one of 0 points, 1 point, 3 points, 5 points, and 6 points as the age score based on the age of the wearer of wearable terminal 1A received by input unit 1A1. In detail, score calculation unit 1A3 calculates 0 point as the age score when the wearer of wearable terminal 1A is under 45 years old. Score calculation unit 1A3 calculates 1 point as the age score when the wearer of wearable terminal 1A is between 45 and 54 years old. Score calculation unit 1A3 calculates 3 points as the age score when the wearer of wearable terminal 1A is between 55 and 64 years old. Score calculation unit 1A3 calculates 5 points as the age score when the wearer of wearable terminal 1A is between 65 and 74 years old. Score calculation unit 1A3 calculates 6 points as the age score when the wearer of wearable terminal 1A is 75 years old or older. Score calculation unit 1A3 calculates a superficial body temperature score of 0, 1, 2, 3, or 4 based on the superficial body temperature of the wearer of wearable device 1A detected by superficial body temperature detection unit 1A21. Specifically, score calculation unit 1A3 calculates a superficial body temperature score of 0 when the superficial body temperature of the wearer of wearable device 1A is 36.0°C or higher and 38.4°C or lower. Score calculation unit 1A3 calculates a superficial body temperature score of 1 when the superficial body temperature of the wearer of wearable device 1A is 38.5°C or higher and 38.9°C or lower, or 34.0°C or higher and 35.9°C or lower. Score calculation unit 1A3 calculates a superficial body temperature score of 2 when the superficial body temperature of the wearer of wearable device 1A is 32.0°C or higher and 33.9°C or lower. Score calculation unit 1A3 calculates a superficial body temperature score of 3 points when the superficial body temperature of the person wearing wearable terminal 1A is between 39.0°C and 40.9°C or between 30.0°C and 31.9°C. Score calculation unit 1A3 calculates a superficial body temperature score of 4 points when the superficial body temperature of the person wearing wearable terminal 1A is between 41.0°C and 41.0°C or less than 30.0°C.
[0033] Score calculation unit 1A3 calculates a heart rate score of 0, 2, 3, or 4 based on the heart rate of the person wearing wearable terminal 1A detected by heart rate detection unit 1A22. In detail, score calculation unit 1A3 calculates a heart rate score of 0 when the heart rate [beats per minute] of the person wearing wearable terminal 1A is 70 or more and 109 or less. Score calculation unit 1A3 calculates a heart rate score of 2 when the heart rate [beats per minute] of the person wearing wearable terminal 1A is 110 or more and 139 or less, or 55 or more and 69 or less. Score calculation unit 1A3 calculates a heart rate score of 3 when the heart rate [beats per minute] of the person wearing wearable terminal 1A is 140 or more and 179 or less, or 40 or more and 54 or less. If the heart rate [beats per minute] of the wearer of wearable device 1A is 180 or more or less than 40, score calculation unit 1A3 calculates a heart rate score of 4 points. The score calculation unit 1A3 calculates one of 0, 2, 3, or 4 points as the mean blood pressure score based on the mean blood pressure of the wearable device 1A detected by the blood pressure detection unit 1A23. Specifically, the score calculation unit 1A3 calculates 0 points as the mean blood pressure score when the mean blood pressure [mmHg] of the wearer of the wearable device 1A is 70 or more and 109 or less. The score calculation unit 1A3 calculates 2 points as the mean blood pressure score when the mean blood pressure [mmHg] of the wearer of the wearable device 1A is 110 or more and 129 or less, or 50 or more and 69 or less. The score calculation unit 1A3 calculates 3 points as the mean blood pressure score when the mean blood pressure [mmHg] of the wearer of the wearable device 1A is 130 or more and 159 or less. The score calculation unit 1A3 calculates 4 points as the mean blood pressure score when the mean blood pressure [mmHg] of the wearer of the wearable device 1A is 160 or more or less or less than 50.
[0034] The score calculation unit 1A3 calculates a blood oxygen concentration saturation score of 0, 1, 3, or 4 based on the blood oxygen concentration saturation (SpO2) of the wearer of the wearable device 1A detected by the blood oxygen concentration saturation detection unit 1A24. In detail, the score calculation unit 1A3 calculates a blood oxygen concentration saturation score of 0 when the blood oxygen concentration saturation [%] of the wearer of the wearable device 1A is 94 or higher. The score calculation unit 1A3 calculates a blood oxygen concentration saturation score of 1 when the blood oxygen concentration saturation [%] of the wearer of the wearable device 1A is 91 or higher and 93 or lower. The score calculation unit 1A3 calculates a blood oxygen concentration saturation score of 3 when the blood oxygen concentration saturation [%] of the wearer of the wearable device 1A is 88 or higher and 90 or lower. If the blood oxygen concentration saturation [%] of the wearer of the wearable device 1A is less than 88, the score calculation unit 1A3 calculates a blood oxygen concentration saturation score of 4 points.
[0035] The score calculation unit 1A3 calculates one of 0 points, 1 point, 3 points, and 4 points as a consciousness disorder score based on the reaction of the wearer of the wearable device 1A to the consciousness disorder evaluation alert detected by the reaction detection unit 1A25. In detail, the score calculation unit 1A3 calculates 0 points as the consciousness disorder score when the response of the wearer of the wearable device 1A to the consciousness disorder evaluation alert corresponds to "0: clear consciousness" in the JCS. In a first example of the monitoring system 1 of the first embodiment, if the time from when the alert output unit 1A4 outputs an alert for evaluating a disorder of consciousness to when the response detection unit 1A25 detects a response from the wearer of the wearable device 1A is less than the threshold T1 [seconds], the score calculation unit 1A3 calculates a disorder of consciousness score of "0 points," which corresponds to "0: clear consciousness" on the JCS, as the response of the wearer of the wearable device 1A to the alert for evaluating a disorder of consciousness. The value of the threshold T1 [seconds] is set in advance through an experiment or the like. In a second example of the monitoring system 1 of the first embodiment, when the acceleration of the movement of the wearer of the wearable device 1A detected by the response detection unit 1A25 (acceleration sensor) is equal to or greater than the threshold G1, the score calculation unit 1A3 calculates a consciousness disorder score of "0 points," which corresponds to "0: clear consciousness" on the JCS, as the response of the wearer of the wearable device 1A to the alert for evaluating consciousness disorder. The value of the threshold G1 is set in advance through an experiment or the like.
[0036] In the example shown in Figure 2, the score calculation unit 1A3 calculates a consciousness disorder score of 1 point if the response of the wearer of the wearable device 1A to the consciousness disorder assessment alert corresponds to the JCS's "1: Orientation maintained but consciousness not clear," "2: Disoriented," or "3: Unable to state own name or date of birth." In a first example of the monitoring system 1 of the first embodiment, if the time from when the alert output unit 1A4 outputs an alert for evaluating consciousness disorder to when the response detection unit 1A25 detects a response from the wearer of the wearable device 1A is equal to or greater than threshold T1 [seconds] and less than threshold T2 (>T1) [seconds], the score calculation unit 1A3 calculates a consciousness disorder score of "1 point," which corresponds to the response of the wearer of the wearable device 1A to the alert for evaluating consciousness disorder as "1: Oriented but not lucid," "2: Disoriented," or "3: Unable to state own name or date of birth" on the JCS. The value of threshold T2 [seconds] is set in advance through an experiment or the like.
[0037] In the example shown in Figure 2, the score calculation unit 1A3 calculates a consciousness disorder score of 3 points if the response of the wearer of the wearable device 1A to the consciousness disorder assessment alert corresponds to the JCS score of "10: opens eyes when called normally," "20: opens eyes when called out loudly or shaken vigorously," or "30: barely opens eyes when called out to while painful stimuli are applied." In a first example of the monitoring system 1 of the first embodiment, in a second example of the monitoring system 1 of the first embodiment, if the response detection unit 1A25 fails to detect the response of the wearer of the wearable device 1A within threshold T2 [seconds], or if the acceleration of the movement of the wearer of the wearable device 1A detected by the response detection unit 1A25 (acceleration sensor) is equal to or greater than threshold G1, score calculation unit 1A3 calculates a consciousness disorder score of "3 points" based on the response of the wearer of the wearable device 1A to the alert for evaluating consciousness disorder, which corresponds to "10: opens eyes when called normally," "20: opens eyes when called out loudly or shaken vigorously," or "30: barely opens eyes when called out while painful stimuli are applied." The value of threshold G1 is set in advance through an experiment or the like.
[0038] In the example shown in Figure 2, the score calculation unit 1A3 calculates a consciousness disorder score of 4 points if the response of the wearer of the wearable device 1A to the alert for evaluating consciousness disorder corresponds to the JCS score of "100: Makes an action such as brushing away pain," "200: Moves limbs or grimaces in response to painful stimuli," or "300: Does not respond at all to painful stimuli." In a first example of the monitoring system 1 of the first embodiment, if the response detection unit 1A25 is unable to detect the response of the wearer of the wearable terminal 1A within threshold T2 [seconds] from the time the alert output unit 1A4 outputs an alert for evaluating a state of consciousness disorder, and the acceleration of the movement of the wearer of the wearable terminal 1A detected by the response detection unit 1A25 (acceleration sensor) is less than threshold G1, the score calculation unit 1A3 calculates a consciousness disorder score of "4 points" based on the response of the wearer of the wearable terminal 1A to the alert for evaluating a state of consciousness disorder, which corresponds to a JCS score of "100: Makes movements such as brushing away pain," "200: Moves limbs or grimaces in response to painful stimuli," or "300: Does not respond at all to painful stimuli."
[0039] In the example shown in Figures 1 and 2, in order to minimize the output of alerts for evaluating consciousness disorders by the alert output unit 1A4, in the first mode (normal mode) of the monitoring system 1 of the first embodiment, the alert output unit 1A4 does not output alerts for evaluating consciousness disorders. Detection unit 1A2 detects biological information of the wearer of wearable device 1A in a state (first mode) in which alert output unit 1A4 is not outputting an alert for evaluating consciousness disorder. In detail, superficial body temperature detection unit 1A21 of detection unit 1A2 detects the superficial body temperature of the wearer of wearable device 1A, heart rate detection unit 1A22 detects the heart rate of the wearer of wearable device 1A, blood pressure detection unit 1A23 detects the mean blood pressure of the wearer of wearable device 1A, and blood oxygen concentration saturation detection unit 1A24 detects the blood oxygen concentration saturation of the wearer of wearable device 1A. Pre-alert score calculation unit 1A31 of score calculation unit 1A3 calculates a severity assessment score (five-item severity assessment score) that does not include an assessment of impaired consciousness based on the age of the wearer of wearable device 1A received by input unit 1A1, the superficial body temperature of the wearer of wearable device 1A detected by superficial body temperature detection unit 1A21, the heart rate of the wearer of wearable device 1A detected by heart rate detection unit 1A22, the mean blood pressure of the wearer of wearable device 1A detected by blood pressure detection unit 1A23, and the blood oxygen concentration saturation of the wearer of wearable device 1A detected by blood pressure detection unit 1A24. In detail, pre-alert score calculation unit 1A31 calculates the severity assessment score (five-item severity assessment score) that does not include an assessment of impaired consciousness by adding the age score, superficial body temperature score, heart rate score, mean blood pressure score, and blood oxygen concentration saturation score.
[0040] In the example shown in Figures 1 and 2, when the severity assessment score (severity assessment score of five items) that does not include the assessment of impaired consciousness calculated by the pre-alert score calculation unit 1A31 of the score calculation unit 1A3 becomes equal to or greater than a threshold value (specifically, 3 points), the monitoring system 1 of the first embodiment switches from the first mode to the second mode. In the example shown in Figures 1 and 2, the monitoring system 1 of the first embodiment switches from the first mode to the second mode when the severity assessment score not including the assessment of impaired consciousness becomes 3 points or more, but in other examples, the monitoring system 1 of the first embodiment may switch from the first mode to the second mode when the severity assessment score not including the assessment of impaired consciousness becomes a number other than 3 points (e.g., 5 points) or more.
[0041] In the example shown in FIGS. 1 and 2, in the second mode of the monitoring system 1 of the first embodiment, the alert output unit 1A4 outputs an alert for evaluating consciousness disorder. Detection unit 1A2 detects biological information of the wearer of wearable device 1A in a state (second mode) in which alert output unit 1A4 is outputting an alert for consciousness disorder evaluation, and detects the reaction of the wearer of wearable device 1A to the alert for consciousness disorder evaluation output by alert output unit 1A4. In detail, superficial body temperature detection unit 1A21 of detection unit 1A2 detects the superficial body temperature of the wearer of wearable device 1A, heart rate detection unit 1A22 detects the heart rate of the wearer of wearable device 1A, blood pressure detection unit 1A23 detects the mean blood pressure of the wearer of wearable device 1A, blood oxygen concentration saturation detection unit 1A24 detects the blood oxygen concentration saturation of the wearer of wearable device 1A, and reaction detection unit 1A25 detects the reaction of the wearer of wearable device 1A to the alert for consciousness disorder evaluation output by alert output unit 1A4. The score calculation unit 1A3 calculates a severity assessment score (six-item severity assessment score) including an assessment of consciousness disorder based on the biometric information of the wearer of the wearable terminal 1A detected by the detection unit 1A2 and the response of the wearer of the wearable terminal 1A to the consciousness disorder assessment alert output by the alert output unit 1A4. Specifically, the post-alert score calculation unit 1A32 of the score calculation unit 1A3 calculates a severity assessment score (six-item severity assessment score) including an assessment of consciousness disorder based on the age of the wearer of the wearable terminal 1A received by the input unit 1A1, the superficial body temperature of the wearer of the wearable terminal 1A detected by the superficial body temperature detection unit 1A21, the heart rate of the wearer of the wearable terminal 1A detected by the heart rate detection unit 1A22, the mean blood pressure of the wearer of the wearable terminal 1A detected by the blood pressure detection unit 1A23, the blood oxygen concentration saturation of the wearer of the wearable terminal 1A detected by the blood oxygen concentration saturation detection unit 1A24, and the response of the wearer of the wearable terminal 1A to the alert for assessing consciousness disorder detected by the response detection unit 1A25. In detail, the post-alert score calculation unit 1A32 calculates a severity assessment score (six-item severity assessment score) including an assessment of impaired consciousness by adding the age score, superficial body temperature score, heart rate score, mean blood pressure score, blood oxygen concentration saturation score, and impaired consciousness score.
[0042] In the example shown in Figures 1 and 2, in the second mode of the monitoring system 1 of the first embodiment, the transmission unit 1A5 transmits to the management server 1B a severity assessment score (six-item severity assessment score) including an assessment of consciousness impairment calculated by the post-alert score calculation unit 1A32 of the score calculation unit 1A3, the superficial body temperature of the person wearing the wearable terminal 1A detected by the superficial body temperature detection unit 1A21, the heart rate of the person wearing the wearable terminal 1A detected by the heart rate detection unit 1A22, the mean blood pressure of the person wearing the wearable terminal 1A detected by the blood pressure detection unit 1A23, the blood oxygen concentration saturation of the person wearing the wearable terminal 1A detected by the blood oxygen concentration saturation detection unit 1A24, and the response of the person wearing the wearable terminal 1A to the alert for assessing consciousness impairment detected by the response detection unit 1A25. The receiving unit 1B1 of the management server 1B receives the severity assessment score (six-item severity assessment score) including the assessment of consciousness impairment transmitted by the transmitting unit 1A5 of the wearable terminal 1A, the superficial body temperature of the wearer of the wearable terminal 1A, the heart rate of the wearer of the wearable terminal 1A, the mean blood pressure of the wearer of the wearable terminal 1A, the blood oxygen concentration saturation of the wearer of the wearable terminal 1A, and the response of the wearer of the wearable terminal 1A to the alert for assessing consciousness impairment. The output unit 1B2 of the management server 1B outputs the severity assessment score (six-item severity assessment score) including the assessment of consciousness impairment received by the receiving unit 1B1, the superficial body temperature of the wearer of the wearable terminal 1A, the heart rate of the wearer of the wearable terminal 1A, the mean blood pressure of the wearer of the wearable terminal 1A, the blood oxygen concentration saturation of the wearer of the wearable terminal 1A, and the response of the wearer of the wearable terminal 1A to the alert for assessing consciousness impairment. Therefore, a user of management server 1B (a person managing the wearer of wearable terminal 1A) can confirm the severity of heatstroke of the wearer of wearable terminal 1A by checking the severity assessment score (six-item severity assessment score) including the assessment of impaired consciousness output by output unit 1B2, the superficial body temperature of the wearer of wearable terminal 1A, the heart rate of the wearer of wearable terminal 1A, the mean blood pressure of the wearer of wearable terminal 1A, the blood oxygen concentration saturation of the wearer of wearable terminal 1A, and the response of the wearer of wearable terminal 1A to the alert for assessing impaired consciousness. In other words, according to the monitoring system 1 of the first embodiment, the output of alerts for evaluating consciousness disorders can be kept to a minimum, while the wearer of the wearable terminal 1A can be appropriately monitored based on a severity assessment score that includes an assessment of consciousness disorders when necessary. Furthermore, according to the monitoring system 1 of the first embodiment, it is expected that the alert for evaluating impaired consciousness will lead to behavioral changes (such as turning on the air conditioner or taking a break from work or sports) even in mild cases (pre-symptomatic cases).
[0043] FIG. 3 is a sequence diagram showing an example of processing executed in the monitoring system 1 of the first embodiment. In the example shown in FIG. 3, in step S10, input unit 1A1 of wearable terminal 1A accepts an input operation for inputting the age of the wearer of wearable terminal 1A. Next, in step S11, detection unit 1A2 of wearable device 1A detects biological information of the wearer of wearable device 1A (not including the reaction of the wearer of wearable device 1A to the alert for evaluating consciousness disorder output by alert output unit 1A4). In detail, superficial body temperature detection unit 1A21 of detection unit 1A2 detects the superficial body temperature of the wearer of wearable device 1A, heart rate detection unit 1A22 detects the heart rate of the wearer of wearable device 1A, blood pressure detection unit 1A23 detects the mean blood pressure of the wearer of wearable device 1A, and blood oxygen concentration saturation detection unit 1A24 detects the blood oxygen concentration saturation of the wearer of wearable device 1A. Next, in step S12, the score calculation unit 1A3 of the wearable terminal 1A calculates a severity assessment score (a severity assessment score that does not include an assessment of impaired consciousness) used to assess the severity of the wearer of the wearable terminal 1A based on the biometric information of the wearer of the wearable terminal 1A detected in step S11. Next, in step S13, the transmitter 1A5 of the wearable terminal 1A transmits the severity assessment score (severity assessment score that does not include an assessment of impaired consciousness) calculated in step S12 and the biometric information of the wearer of the wearable terminal 1A to the management server 1B, and the output unit 1B2 of the management server 1B receives the severity assessment score (severity assessment score that does not include an assessment of impaired consciousness) and the biometric information of the wearer of the wearable terminal 1A. Next, in step S14, the output unit 1B2 of the management server 1B outputs the severity assessment score (the severity assessment score not including the assessment of impaired consciousness) received in step S13 and the biometric information of the wearer of the wearable terminal 1A.
[0044] In the example shown in FIG. 3, in step S15, the severity assessment score not including the assessment of consciousness disorder becomes equal to or greater than a threshold value (for example, 3 points), and the alert output unit 1A4 of the wearable device 1A outputs an alert for the assessment of consciousness disorder. Next, in step S16, the detection unit 1A2 of the wearable terminal 1A detects the biometric information of the wearer of the wearable terminal 1A when the alert output unit 1A4 is outputting an alert for evaluating consciousness disorder, and the reaction of the wearer of the wearable terminal 1A to the alert for evaluating consciousness disorder output by the alert output unit 1A4. Next, in step S17, the score calculation unit 1A3 of the wearable terminal 1A calculates a severity assessment score including an assessment of consciousness disorder based on the biometric information of the wearer of the wearable terminal 1A detected in step S16 and the response of the wearer of the wearable terminal 1A to the alert for assessing consciousness disorder output by the alert output unit 1A4. Next, in step S18, the transmitter 1A5 of the wearable terminal 1A transmits the severity assessment score including the assessment of consciousness disorder calculated in step S17, the biometric information of the wearer of the wearable terminal 1A, and the response of the wearer of the wearable terminal 1A to the alert for assessing consciousness disorder to the management server 1B, and the output unit 1B2 of the management server 1B receives the severity assessment score including the assessment of consciousness disorder, the biometric information of the wearer of the wearable terminal 1A, and the response of the wearer of the wearable terminal 1A to the alert for assessing consciousness disorder. Next, in step S19, the output unit 1B2 of the management server 1B outputs the severity assessment score including the assessment of consciousness disorder received in step S18, the biometric information of the wearer of the wearable terminal 1A, and the response of the wearer of the wearable terminal 1A to the alert for assessing consciousness disorder.
[0045] <Example> The inventors used the occurrence of heatstroke (core body temperature of 40°C or higher, GCS of 8 or lower) when the patient arrived at the hospital as an evaluation criterion for heatstroke. When the core body temperature is 40°C or higher and the GCS of 8 or lower, active cooling (active cooling of the whole body) is important for improving outcomes, so in this case it is necessary to transport the patient to the hospital immediately. The inventor evaluated the consciousness level of the wearer of the wearable terminal 1A based on the wearer's response to a consciousness disorder assessment alert that is output when the severity assessment score, which does not include an assessment of consciousness disorder, reaches 3 points or more. The inventor used as evaluation items the age of the wearer of the wearable terminal 1A, the superficial body temperature of the wearer of the wearable terminal 1A, the heart rate of the wearer of the wearable terminal 1A, the mean blood pressure of the wearer of the wearable terminal 1A, the blood oxygen concentration saturation of the wearer of the wearable terminal 1A, and the response of the wearer of the wearable terminal 1A to the alert for evaluating impaired consciousness output by the alert output unit 1A4. The inventor calculated a severity assessment score (pre-alert score) that does not include an assessment of impaired consciousness based on the age of the wearer of wearable terminal 1A, the superficial body temperature of the wearer of wearable terminal 1A, the heart rate of the wearer of wearable terminal 1A, the mean blood pressure of the wearer of wearable terminal 1A, and the blood oxygen concentration saturation of the wearer of wearable terminal 1A, and calculated a severity assessment score (post-alert score) that includes an assessment of impaired consciousness based on the age of the wearer of wearable terminal 1A, the superficial body temperature of the wearer of wearable terminal 1A, the heart rate of the wearer of wearable terminal 1A, the mean blood pressure of the wearer of wearable terminal 1A, the blood oxygen concentration saturation of the wearer of wearable terminal 1A, and the wearer of wearable terminal 1A's response to the alert for assessing impaired consciousness.
[0046] The inventors evaluated the severity of heatstroke in 1,089 cases (excluding CPA cases (cases of cardiac arrest before the hospital) and cases in which oxygen was administered) for which information before and at the time of admission was clear in the Heat Stroke Study conducted by the Japanese Society of Acute Medicine from 2008 to 2020.
[0047] Figure 4 shows the relationship between the severity assessment score, the number of patients, and the incidence rate and number of cases of heatstroke (core body temperature 40°C or higher, GCS 8 or lower) in an example of the monitoring system 1 of the first embodiment. In detail, Figure 4(A) shows the relationship between the pre-alert score and the number of patients in an example of the monitoring system 1 of the first embodiment, and Figure 4(B) shows the relationship between the post-alert score and the number of patients in an example of the monitoring system 1 of the first embodiment. Figure 5 shows a comparison of the relationship between the severity assessment score (horizontal axis) and the incidence rate of heatstroke (core body temperature 40°C or higher, GCS 8 or lower) in an example of the monitoring system 1 of the first embodiment, between the pre-alert score and the post-alert score.
[0048] The inventors have investigated the threshold value (score of the severity evaluation score that does not include the evaluation of impaired consciousness) at which the monitoring system 1 switches from the first mode to the second mode. When the threshold for switching from 1st mode to 2nd mode for Monitoring System 1 was set at 3 points, the incidence rate before the alert was 0.0%, but when the impaired consciousness score was 4 points, it rose to 7 points after the alert, resulting in an incidence rate of 7.7%. A threshold of 3 points is thought to be an appropriate timing for encouraging early behavioral change. When the threshold for switching from the first to second mode in Monitoring System 1 was set to 5 points, the incidence rate was 7.8% just before the alert, and if there was no loss of consciousness, the incidence rate was 0.0% at 5 points after the alert, and if there was loss of consciousness, the incidence rate was 10.9% at 9 points after the alert. The general rule is to encourage behavioral change and transport the patient to a hospital if there is loss of consciousness, but it may also be possible to monitor the patient's condition in a first-aid room or other location. When the threshold for switching from the first to second mode in Monitoring System 1 was set to 8 points, the success rate was 13.3% before the alert, 2.4% after the alert if there was no loss of consciousness at 8 points, and 11.6% if there was loss of consciousness at 12 points after the alert. If there was no loss of consciousness, it was possible to encourage behavioral change. In cases where there was loss of consciousness, the general rule was to transport the patient to the hospital, and it became difficult to monitor the patient's condition unless proactive measures were taken in the emergency room, etc. When the threshold for switching from the first mode to the second mode for Monitoring System 1 was set to 10 points, the success rate was 17.1% before the alert, 4.8% after the alert if there was no loss of consciousness at 10 points, and 26.9% if there was loss of consciousness at 14 points after the alert. It is possible to encourage behavioral change, but if there is loss of consciousness, it is more appropriate to transport the patient to a hospital than to a first aid room. When the threshold for switching from the first to second mode in Monitoring System 1 was set to 12 points, the success rate was 23.6% before the alert, 11.6% after the alert if there was no loss of consciousness at 12 points, and 43.3% if there was loss of consciousness at 16 points after the alert. Even if there is no loss of consciousness, it is recommended that remote monitoring be stopped and a direct visit be made to check on the patient. If there is loss of consciousness, immediate transport to the hospital is necessary. When the threshold for switching from the first mode to the second mode for Monitoring System 1 was set at 14 points, the success rate was 29.5% before the alert, and even if there was no loss of consciousness, it rose to 26.9% at 14 points after the alert. If there was loss of consciousness, it rose to 58.8% at 18 points after the alert. Even if there was no loss of consciousness, this was a level at which it was advisable to transport the patient to a hospital. If there was loss of consciousness, there was a high probability that the patient would require emergency medical treatment.
[0049] [Second embodiment] A second embodiment of the monitoring system, wearable terminal, monitoring method, and program of the present invention will be described below. The monitoring system 1 of the second embodiment is configured similarly to the monitoring system 1 of the first embodiment described above, except for the points described below. Therefore, the monitoring system 1 of the second embodiment can achieve the same effects as the monitoring system 1 of the first embodiment described above, except for the points described below.
[0050] The monitoring system 1 of the second embodiment is configured similarly to the monitoring system 1 of the first embodiment shown in Fig. 1. Like the monitoring system 1 of the first embodiment, the monitoring system 1 of the second embodiment monitors the wearer of the wearable device 1A. In detail, the monitoring system 1 of the second embodiment monitors the severity of a disease other than heat stroke in the wearer of the wearable device 1A. In other words, the monitoring system 1 of the second embodiment is used to prevent the aggravation of a disease other than heat stroke in the wearer of the wearable device 1A.
