Description

Technical Field

[0001] The present invention relates to the field of medical emergency technology, and in particular to an examination item scheduling system and method based on patient examination demand optimization. Background Art

[0002] In the modern medical system, the emergency department, as the front line for dealing with acute and critically ill patients, bears the important responsibility of responding quickly and diverting patients. Faced with a large number of emergency patients with different conditions, the effective allocation and priority judgment of medical resources are crucial. In the existing technology, the patient's condition is usually graded through manual experience and a simple scoring system, and the order of diagnosis and treatment is arranged accordingly. However, due to the high pressure and complexity of the medical environment, the existing diversion mechanism has certain limitations.

[0003] Specifically, in the existing triage technology, since the judgment of the severity of the patient's condition mainly depends on the subjective experience of medical staff or simple fixed parameters, it is easy to lead to errors in priority judgment. Once some critically ill patients are not identified and assigned priority in time, it may lead to delayed emergency response, which in turn poses a threat to the patient's life safety. For example, in patients with cardiac arrest or stroke who require rapid interventional treatment, delaying the golden time for treatment will significantly increase the mortality rate and the incidence of sequelae. In addition, the triage method that relies too much on experience may also be affected by subjective factors such as the working status and experience level of medical staff, further exacerbating the inconsistency of triage results. In general, the existing technology faces the following main problems in the triage of patients in the emergency department: First, the judgment accuracy of the triage priority is low, which can easily lead to critically ill patients being misjudged as secondary conditions; second, there is a lack of dynamic response capabilities to changes in the patient's condition, and the impact of real-time data on triage decisions is not fully considered. These problems limit the improvement of emergency triage efficiency, and at the same time cannot fully meet the patient's demand for fast and safe medical services. Summary of the invention

[0048] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] like Figure 1 As shown, the present invention provides a technical solution: a system for scheduling examination items based on patient examination demand optimization, the system comprising:

[0050] Information acquisition module, used to obtain the patient's basic information and emergency examination needs;

[0051] A priority assessment module, which is used to assess the priority of patients based on their vital signs and the severity of their illness;

[0052] The scheduling generation module is used to generate an optimized examination item schedule to ensure that high-priority patients are examined first;

[0053] The status monitoring module is used to monitor the patient's status in real time and dynamically adjust the inspection project schedule according to the status changes. Specifically, the patient's initial vital signs are used as the state vector. Based on the dynamic changes of the patient's status over time, the vital signs at the next moment are predicted. Combined with the real-time monitoring data, the Kalman filter is used to update the patient's status estimate. If the estimate exceeds the set threshold, the dynamic adjustment mechanism is triggered to update the schedule. The specific formula is:

[0054]

[0055] K k =P k|k-1 H T (HP k|k-1 H T +R) -1 ;

[0056] in, represents the estimated value of the state at the current time k, represents the estimated value of the predicted state, K k represents the Kalman gain, z k represents the actual measurement value of k at the current moment, H represents the measurement matrix, P k|k-1 represents the prediction covariance matrix, H T represents the transpose of the measurement matrix, R represents the measurement noise covariance;

After the schedule is generated, the system monitors the dynamic changes of the patient's vital signs in real time through the state monitoring module, predicts the patient's state in combination with the Kalman filter algorithm, and updates the state estimation value in real time. When the state estimation value exceeds the set threshold, the dynamic adjustment mechanism is triggered to update the schedule to ensure the urgency of the examination items and the efficiency of resource utilization. Finally, the result sending module sends the optimized schedule to the medical equipment and doctor terminal for guiding the actual examination operation. Through the priority evaluation module and the dynamic scheduling mechanism, it is ensured that high-priority patients can be examined first and the efficiency of medical resource utilization is optimized. The state monitoring module, combined with the Kalman filter algorithm, can dynamically adjust the schedule for the examination items and improve the intelligence level of the system. Through real-time prediction and dynamic adjustment, the response speed and accuracy of emergency examinations are improved, the waiting time of patients is reduced, and the quality of emergency medical services is improved.

[0059] The information acquisition module obtains the patient's basic information and emergency examination requirements, including a data interface unit, which is used to connect with the hospital management system and the electronic medical record system to automatically obtain the patient's basic information and emergency examination requirements; a user input unit, which is used to receive patient information and special examination requirements manually entered by medical staff. Through the data interface unit, the system automatically extracts the patient's basic information and emergency examination requirements from the hospital management system and the electronic medical record system to avoid information omissions and improve information collection efficiency. The user input unit provides a flexible entry interface for special situations, such as emergency referrals or sudden examination requirements of patients, to ensure that the system can respond in real time.

The parameter collection unit collects the patient's core vital signs data in real time, and the priority calculation unit inputs the data into a weight distribution algorithm or a scoring model. According to the degree of abnormality of the vital signs and the importance of the emergency needs, the patient's priority score is calculated for generating a scheduling strategy. Provide real-time and accurate patient priority assessment results to ensure the scientific nature of medical resource allocation.

The data monitoring unit continuously collects the patient's vital signs data, monitors abnormal fluctuations in the patient's status, triggers the scheduling adjustment unit to recalculate the priority, and adjusts the time schedule of the inspection items to ensure that emergencies are responded to quickly. Dynamically adjust the schedule to improve the system's ability to respond to sudden patient conditions, reduce inspection delays caused by changes in the patient's condition, and improve inspection results.

[0063] The result sending module sends the final inspection item schedule to the corresponding medical equipment and doctor terminal, including a data encryption unit for encrypting the inspection item schedule to ensure the security of the data during transmission; a message distribution unit for sending the inspection item schedule to the corresponding medical equipment and doctor terminal through the network, and providing arrival confirmation information. After the result sending module completes the generation of the inspection item schedule, it first encrypts the form through the data encryption unit, using, for example, the AES (Advanced Encryption Standard) algorithm to protect sensitive information. After encryption is completed, the message distribution unit sends the form to the target device or terminal, monitors whether the message is successfully delivered, and reports the confirmation status to the system. Improve the security of patient data transmission and prevent data leakage or illegal access. Provide transmission confirmation information to ensure that the schedule is reliably delivered to the receiving end and avoid medical delays caused by information loss.

The automatic update unit continuously synchronizes with the hospital management system to receive new or updated patient information in real time. The multi-source information integration unit classifies and organizes data from different departments or equipment to ensure the integrity and consistency of the scheduling table information. Ensure the real-time update of patient information and improve the accuracy of examination scheduling. Integrate information from multiple sources to reduce duplicate examinations and improve the utilization rate of medical resources.

It includes a time window calculation unit, which is used to dynamically plan the patient's inspection time according to the available time period of the inspection equipment; a parallel task scheduling unit, which is used to parallelly schedule inspection items that can be executed simultaneously by the same equipment to reduce patient waiting time. The time window calculation unit allocates the best inspection time to each patient by calculating the idle time period of the equipment and the priority time constraints of the patient. When the equipment supports parallel inspection, the parallel task scheduling unit reasonably arranges the inspection items to maximize the utilization of equipment resources. Improve the utilization efficiency of medical equipment, reduce the overall inspection waiting time of patients, realize multi-task scheduling of equipment, and optimize the inspection process.

[0066] The status monitoring module monitors the patient's status in real time and dynamically adjusts the inspection item schedule according to the status changes. It includes an abnormal warning unit, which is used to detect abnormal changes in the patient's vital signs and send an alarm to medical staff when the threshold is triggered; a status change recording unit, which is used to record the patient's vital sign change trend and provide historical data support for priority adjustment.
