APPARATUS AND METHOD FOR PERFORMING AN EDUCATIONAL VIDEO-BASED RESPONSE TO AN ABNORMAL CONDITION OF A VENTILATOR-APPLIED PATIENT IN A COMMUNICATION SYSTEM }

The present invention relates to an apparatus and method for performing an educational video-based response to an abnormal state of a patient to which a ventilator is applied in a communication system. Specifically, the present invention relates to a ventilator device transmitted using a communication terminal of a caregiver of the patient and the patient's condition when an abnormal condition occurs in a patient to which a home ventilator is applied after being discharged from the hospital. Mobile disease inspection to reduce the work intensity of medical personnel in charge of patients by firstly providing training videos prepared in advance at the hospital server level and selecting cases requiring direct connection to medical personnel for abnormal conditions secondarily It relates to an apparatus and method.

Due to population aging, increased disease morbidity, and advances in science and technology, the number of patients dependent on mechanical ventilation is increasing worldwide, accounting for 40% of the intensive care unit bed share. In the past, most patients applying ventilators were hospitalized in an intensive care unit and received long-term care. As a result, the burden of medical expenses due to insufficient intensive care unit beds and long-term financial resources has been caused, and the treatment purpose is changing from stabilization after acute resuscitation to rehabilitation and chronic disease-oriented disease structure. Most household ventilators are applied in an invasive way through a tracheotomy or a non-invasive method using a mask after failing to break away from mechanical ventilation. Globally, the number of patients dependent on home ventilators is increasing by 0.3 per 100,000 annually.

Even after medical stabilization, it is a complicated and difficult process for a patient who has applied a home ventilator to be discharged home due to the severity of the patient and the complexity of management. Therefore, in order to facilitate discharge, it is necessary to develop a standardized discharge process in which families participate and an educational program that enhances the management ability of family members and caregivers after installing a home ventilator.

60% of patients with home ventilators were re-hospitalized after being discharged home, and within 6 months was the highest at 38%, of which 50% were admitted to the intensive care unit due to deterioration of their condition. The factors affecting readmission were the length of stay, the period of application of the ventilator, and whether or not oxygen was used upon discharge. In particular, the number of readmissions increases due to the progression of existing diseases or sudden emergencies, and when rehospitalized with a home ventilator attached, the hospitalization period becomes longer, and hospitalization in the intensive care unit is often the case, resulting in successful treatment after treatment. Difficulty returning home. Additionally, 49% of deaths were unexpected, which identified the three main causes of preventable death: inadequate training in resolving ventilator alarms and circuit problems; inadequate response to tracheostomy tube dislocation and medical device failure; and sleep deprivation. Lack of alert vigilance by caregivers due to lack and fatigue.

There was no difference in the frequency of emergencies at home or institution, but emergencies, together with the frequency of readmission, appeared to affect mortality. In the case of children who applied a home ventilator through a tracheotomy tube, the mortality rate was 27% to 43%, and death due to deterioration of the underlying condition was only 34%, and 49% was unexpected. Depending on whether invasive or non-invasive ventilation was used, ventilator dependence, patient's diagnosis, and functional ability including consciousness, safety problems occurred in 30% of patients after tracheotomy due to improper use by caregivers. In particular, the main causes of safety incidents related to equipment were found to be related to malfunctions or alarm problems of the respirator, and disconnection of the respirator circuit. 76% of home ventilator-related safety accidents occurred in patients receiving ventilation through a tracheotomy tube, 39% of which were equipment and mechanical problems, and 30% were caused by caregivers' improper equipment operation. There have been reports of patients dying as a result. 30% of patients with safety events can cause serious damage and life-threatening fatal consequences, and caregivers, including family members, appear to be the main subjects involved. Safety events due to improper ventilator management can lead to emergencies, so risk assessment related to household ventilators is an important part of discharge planning.

Despite the development of patient monitoring systems and technologies that apply ventilators at home, preventable mortality is reported to be 18-20% of all deaths, and the main factor is the error of caregivers, including caregivers. In order to reduce readmission and mortality due to safety events that may occur during home care, pre-hospital education on the knowledge and skills of family care providers is important. In particular, in order to prevent care providers from inadequate training and lack of coping with emergencies, safe and effective patient management training for the most common emergencies, such as hypoxia, increased sputum secretion, and dyspnoea, should be included, and home management on correct equipment operation should be included. training in best practices is required. Based on the educational content, it is important to continuously monitor the care provider, such as evaluating the actual care provider's performance after being discharged from the hospital and identifying the performance level and obstacles to safe management.

If the server of the hospital can receive the ventilator device and the patient's condition using the communication system, it is possible to perform remote education on an appropriate response plan to the care provider in the home. In addition, if it is possible to classify categories by standardizing the ventilator device and the patient's condition, and to respond primarily by providing pre-prepared educational videos according to each category classification, hospital medical personnel can remotely can reduce the effort to respond. In addition, if the severity of the ventilator device and the patient's condition is calculated and a notification message is transmitted to the medical personnel in the hospital as a secondary response selectively according to the severity, the patient to whom the ventilator is applied efficiently at home by utilizing limited medical resources can be managed remotely.

In relation to the ventilator, the device or patient's problem may be categorized into alarm types based on the types of various numerical values measured by the ventilator device. Depending on the category, if an exemplary response plan is prepared as an educational video in advance and the corresponding response plan is provided to the caregiver's terminal through the server, limited medical resources are efficiently operated to solve problems in situations far away from medical personnel, such as at home. and reduce the re-hospitalization rate of discharged patients.

Therefore, there is a need for an apparatus and method for performing an educational video-based response to an abnormal state of a patient to which a ventilator is applied in a communication system.

In step S503, the server determines whether the first severity exceeds a threshold severity. Whether or not the threshold severity is exceeded corresponds to whether or not the abnormal condition is so serious that medical personnel must respond immediately.

In step S504, when the first severity exceeds the threshold severity, first abnormality information is transmitted to the second terminal of the medical personnel corresponding to the patient. Since the ventilator is a device directly related to the patient's life, when the first severity exceeds the critical severity, information on the abnormal state is transmitted directly to the second terminal of the medical personnel in charge.

In step S505, the server forwards and transmits an action message corresponding to the first abnormality information received from the second terminal to the first terminal. According to an embodiment, a voice or video call may be performed between a medical practitioner's terminal and a caregiver's terminal through the mediation of a server at the request of a medical person.

In step S506, if the first severity is less than or equal to the critical severity, the server selects a first training video corresponding to the first abnormality information among a plurality of pre-stored training videos and transmits the first training video to the first terminal. According to various embodiments of the present disclosure, the server may select an educational video corresponding to a first category from among a plurality of pre-stored educational videos corresponding to each of a plurality of predetermined abnormal state categories.

Device or patient problems related to the ventilator can be categorized as described above with reference to FIG. 1 . The types of alarms can be categorized based on the types of various numerical values measured by the ventilator device. Depending on the category, if an exemplary response plan is prepared as an educational video in advance and the corresponding response plan is provided to the caregiver's terminal through the server, limited medical resources are efficiently operated to solve problems in situations far away from medical personnel, such as at home. and reduce the re-hospitalization rate of discharged patients.

According to various embodiments of the present invention, a plurality of educational videos are provided in a predetermined category, for example, (1) apnea - maintenance of apnea time, (2) airway pressure - above or below the upper limit of airway pressure, (3) Ventilation volume - one-time ventilation volume, ventilation volume per minute above or below the upper limit, (4) respiratory rate - above the upper limit of respiratory rate, (5) power source, oxygen, compressed air error - power source or gas pressure error can be subdivided and stored in advance . The predetermined category for the plurality of educational videos is exemplary and may be determined differently according to settings.

According to various embodiments of the present invention, the plurality of educational videos are abnormal state types of numerical values even within a pre-determined category, for example, above the upper limit of airway pressure, below the lower limit of airway pressure, below the lower limit of ventilation volume, and above the upper limit of ventilation volume It can be subdivided and stored in advance, such as more than the upper limit of the respiratory rate.

In step S507, after a predetermined time has elapsed from the time of transmitting the first training video to the first terminal, the server determines whether the device identification information, patient identification information, and the ventilator device are abnormal from the first terminal. Second abnormality information including abnormality information and second patient condition information of the patient is received. The server determines a second severity for the patient and the ventilator device based on the second abnormality information, and when the second severity exceeds a threshold severity, determines whether to notify the medical personnel based on the second abnormality information, When the notification to the medical personnel is determined, the second abnormality information is transmitted to the second terminal. Depending on the caregiver, it may not be easy to understand the educational video and may not be able to solve the problem. Therefore, when the educational video is provided, the server needs to check whether the problem has been resolved through feedback. For problems in the same category, if the problem is not resolved but rather worsens, it is necessary to inform the health care provider directly. However, if a new problem in a different category has just occurred, if the severity is less than the critical level, or if the problem in the same category has recurred but the degree of aggravation is low, it can be replaced by providing an educational video instead of notifying medical personnel.

According to various embodiments of the present disclosure, in order to determine the second severity of the patient and the ventilator device based on the second abnormality information, the server determines the second device abnormality information and the second device abnormality information among a plurality of predetermined abnormal condition categories. A second category corresponding to the patient condition information is determined, and numerical threshold values corresponding to the second category among predetermined abnormal numerical threshold values for each of a plurality of predetermined categories are compared with the second device abnormality information and the second patient condition information. A second severity level can be determined.

According to various embodiments of the present disclosure, in order to determine whether to notify the medical personnel based on the second abnormality information, the server determines whether the first category and the second category are the same, and determines whether the first category and the second category are identical.
