Description

Early warning system

This creation is about an early warning system, especially an early warning system that screens out critically ill patients with a potentially worsening crisis and alerts them.

In-hospital cardiac arrest (IHCA) is an important patient safety issue. The hospital's cardiac arrest is also an important quality indicator for hospitals to monitor and maintain the life safety of hospitalized patients. For patients, a heartbeat will cause the patient to face a great life crisis. Even if they survive, they will face the risk of tracheotomy, use of respirators, or vegetatives. For hospitals, a heartbeat will increase. According to the literature, the inpatients can be diagnosed early by some indicators before the heartbeat stops. In the early stage when the patient's condition starts to be wrong and worsens, timely diagnosis and treatment can effectively reduce the heartbeat in the hospital. Therefore, it is a necessary means to predict the crisis and let the medical team make correct medical treatments early to reduce the death of patients.

In general, a hospital has set up a rapid response team to raise awareness of unintended medical incidents in the hospital. The purpose of the rapid response team is to reduce mortality by early intervention by an emergency and critical professional team, when the clinical warning system ( The Clinical Alert System (CAS) meets pre-set conditions, including the patient's heartbeat, rapid changes in breathing and blood pressure, or rapid changes in mental state. The hospital calls the rapid response team to dispose of it in advance to avoid sudden onset of the patient's condition. The ground is getting worse.

However, the scoring system mechanism of the conventional clinical warning system is one-way management, and the limited medical assistance and medical resource mastery necessary for the high-risk patients are limited, so that the evaluation cannot be performed efficiently. The condition of risk patients, therefore, the conventional clinical warning system lacks a complete method management system to analyze the trend of potential high-risk patients.

In view of this, the conventional early warning system does have the need to improve.

In order to solve the above problems, the purpose of this creation is to provide an early warning system that can more accurately screen critically ill patients with potentially worsening crises to reduce the incidence of heartbeat in the hospital, thereby improving the overall medical environment efficiency.

In this embodiment, the output interface 3 can be connected to a ward-specific dynamic billboard used by the hospital, a physician information system, a nursing information system, and a medical record writing system, so as to more comprehensively monitor the condition of all hospitalized patients in the hospital. When the output interface 3 receives a warning signal from a patient, the patient's name is color-changed, and if it turns red, it is used to warn the medical staff to intervene in time, or the medical staff can notify the emergency and critical professional team as soon as possible. Treatment to control the condition of the patient.

Among them, the early warning system of this creation adopts the dual-track monitoring method to establish a control and protection mechanism. The average index of the patient is judged once every half hour according to the first track. The total index is more than 7 points, that is, the disease The name of the patient is changed to a red warning. The second track judges the total index of the patient whose name is reddish every four hours. If the total index reaches 7 points or more for three consecutive times, the name of the patient is The red flashing warning is used to warn the medical staff that the condition of the patient has not improved or even gradually deteriorated and needs to be processed continuously.

When the patient whose name is red reminded or the patient whose name is red flashing is diagnosed and treated by the medical staff, if the total index is less than 7 points, the patient's name will be yellowed and reminded. In order to remind the medical staff to pay attention to the condition of the patient, if the total index is less than 7 points within 48 hours, the discoloration reminder will be cancelled.

In addition, the output interface 3 can be set in a screen protection program of a computer used by a medical staff in a hospital, or a customized screen protection program can be customized for each ward, so that medical personnel can get a more comprehensive instant reminder.

Through the foregoing description, for patients with critical illness, using the early warning system of the creation, the clinician informs the nurses to recognize the early warning signs, and through the team monitoring, find out the patients in critical condition for immediate assessment, further diagnosis and treatment, In order to prevent the heartbeat from stopping in the hospital, and with the early warning system of the creation, the hospital can more fully assess the risk of the patient, and the patient is transferred to the intensive care unit with an objective basis, so that the critically ill patients can be transferred to the care in the fastest time. First aid and treatment in the ward.

In summary, the early warning system of this creation regularly evaluates the vital signs of the patient. When the patient has a warning that meets the system settings, the emergency department and the intensive professional team can be notified to detect and intervene early to reduce the density of heartbeat in the hospital.
