Abstract
Description
Technical Field
[0001] The invention relates to a clinical intelligent monitoring method for preventing infection at an orthopedic surgical site. Background Art
[0002] Surgical site infection (SSI) is a common and serious postoperative complication that poses a significant challenge to hospital infection prevention and control.
[0003] According to research published in the United States, surgical site infections occur in 2%-25% of surgical operations, and the risk of death in patients can increase by 2-11 times. It is estimated that about 750,000 surgical site infections occur in the United States each year. In addition to increasing morbidity and mortality, surgical site infections also prolong patient hospitalization and increase resource utilization costs. Surgical site infections cost the United States approximately $3.5 billion to $10 billion in healthcare costs each year. Since the Centers for Disease Control and Prevention (CDC) issued guidelines for the prevention of surgical site infections in 2017, several countries and societies have issued guidelines for the prevention of surgical site infections and published evidence-based practices to reduce the risk of surgical site infections. According to relevant statistics, the incidence of surgical site infections in orthopedic surgery is as high as 27.8%. This statistic highlights the urgency of taking effective preventive measures in the field of orthopedic surgery.
[0004] In order to improve the safety and patient satisfaction of orthopedic surgery, it is crucial to explore and implement innovative prevention strategies. Existing studies have shown that most surgical site infections are preventable by following evidence-based preventive measures. These measures mainly focus on managing risk factors throughout the entire surgical process, including but not limited to teamwork, surgical skills, standardization of surgical hand disinfection, aseptic operation, and operating room environmental control. Despite the existence of a series of preventive measures, existing technologies are insufficient in monitoring and evaluating the aseptic operation of medical staff. In particular, there is a lack of an effective method to record and quantify the impact of medical staff behavior on the surgical outcomes of orthopedic patients, which limits the evaluation of the implementation of preventive measures and the optimization of infection control strategies, and cannot evaluate the efficacy of the relevant nodes of the prevention of orthopedic surgical site infections.
[0005] Related studies have pointed out that the operating behaviors of medical staff, especially their technical habits in aseptic operation, have a direct impact on the incidence of surgical site infection. These behaviors are also closely related to key medical outcomes such as the success rate of surgical operations, the quality of life of patients, and survival rate.
[0006] The standardization and correctness of medical staff's surgical and dressing change operation behaviors, especially the establishment of new medical staff's operating habits, have a significant impact on reducing the incidence of orthopedic surgical site infection. However, there is no systematic study on medical staff's surgical and dressing change operation behaviors at home and abroad. Summary of the invention
[0007] Purpose of the invention: The present invention aims to improve the problems existing in the above-mentioned prior art, that is, the present invention discloses a clinical intelligent monitoring method for preventing orthopedic surgical site infection. The present invention combines the measurement system of Internet of Things technology, data communication technology, database technology and mathematical modeling tools, aiming to improve the standardization of aseptic operation behavior of medical staff, thereby effectively reducing the incidence of surgical site infection.
[0008] The present invention establishes a standard reference system, measures the operation behavior and forms a data index based on the relationship between the recorded operation behavior data and the reference system data, and provides a new index for effectively evaluating the behavior-based surgical site infection prevention node. This method not only provides a new perspective for the prevention of surgical site infection, but also provides a scientific basis for improving the standardization and safety of surgical operations.
[0009] Technical solution: A clinical intelligent monitoring method for preventing orthopedic surgical site infection, the steps are as follows:
[0010] Step (1), using an intelligent machine vision system to convert the orthopedic surgery video signal into analog video signal data of the human skeleton trajectory in real time, desensitizing the operation behavior of the video character acquisition object in the analog video signal data, realizing real-time video compression and simulation of the camera captured video, and then entering step (2);
[0011] (2) The desensitized analog video signal data is transmitted to the data processing module. According to the preset target requirements, the data processing module sequentially performs data differentiation, data definition, and real-time data processing of the desensitized analog video signal data, and then forms a report form in combination with the data with a feasible solution, so that the desensitized analog video signal data has the corresponding data fields required by the target, and then enters step (3);
[0012] (3) Automatically package the data processed in step (2), encrypt and transmit to the database, and then proceed to step (4);
[0013] (4) receiving and decrypting the encrypted data packet sent in step (3), and performing granular disassembly, data standardization encoding and data granular reorganization on the data packet in sequence according to the clinical analysis purpose, and then proceeding to step (5);
[0014] (5) Compare the real-time data reorganized by granulation in step (4) with the reference data with the same coding standard stored in the database in advance to obtain the difference value between the two, and then proceed to step (6);
[0015] (6) The difference values of the two obtained in step (5) are converted and summarized into corresponding quantitative indicators, that is, the operation behavior score is obtained to determine whether there is an operation error. If there is an operation error, the operation error warning is displayed and the operation is terminated. If there is no operation error, the operation is terminated.
[0016] Furthermore, the intelligent machine vision system in step (1) includes a machine vision system, an AI system and a pattern recognition system.
[0017] Furthermore, in step (1), an intelligent machine vision system is used to monitor the detailed steps and time required for medical staff to perform surgical hand disinfection, wherein:
[0018] The intelligent machine vision system will evaluate whether the medical staff's hand disinfection process strictly follows the established hygiene standards. If any non-compliant operations are detected, the intelligent machine vision system will automatically send out a warning signal to prompt the medical staff to re-execute the hand hygiene process to ensure the safety of the operation.
[0019] Furthermore, in step (1):
[0020] A dedicated intelligent machine vision system is deployed at the entrance of the operating room. After the operation begins, the intelligent machine vision system will continuously monitor the entry and exit of medical staff. Once it detects that the flow of medical staff exceeds the preset threshold, the intelligent machine vision system will issue an early warning message to maintain the sterile environment of the operating room.
[0021] Furthermore, the preset threshold is 10 persons.
[0022] Furthermore, in step (1): based on the identity and duties of the medical staff, an intelligent machine vision system is used to monitor the position and range of activities of the medical staff in the operating room, wherein:
[0023] The surgeon and the instrument nurse are restricted to activities within the sterile area;
[0024] Circulating nurses and anesthesiologists should stay in the area surrounding the surgery and are strictly prohibited from crossing the sterile area;
[0025] Once it is discovered that the medical staff's standing position and range of activities do not comply with the standing rules, the intelligent machine vision system will issue a warning message.
[0026] Furthermore, in step (1):
[0027] A dedicated intelligent machine vision system is deployed at the entrance of the dressing room to identify the medical staff's information and check whether they are wearing masks, hats, and gloves correctly.
[0028] During the dressing change process, the intelligent machine vision system will monitor whether medical staff strictly follow aseptic operation and hand hygiene standards to ensure the safety and effectiveness of wound dressing changes;
[0029] If the intelligent machine vision system detects improper operation or violation of regulations, it will issue an early warning message to guide medical staff to take correct operating steps.
[0030] Furthermore, the data processing module in step (2) exists in the form of a mobile phone application.
[0031] Furthermore, in step (2), the data processing module also performs data cleaning on the desensitized analog video signal data before performing data differentiation, data definition, and real-time data processing of assigning time and spatial position attributes to the desensitized analog video signal data.
[0032] The present invention utilizes the newly developed "machine vision and AI pattern recognition technology" with Internet of Things function to automatically transmit the real-time remote data of medical staff at the corresponding time nodes specified in surgical hand disinfection, operating room personnel entry and exit, operating room position and activity range, and aseptic dressing change behavior to a predetermined database, and constructs a standard reference system for surgical hand disinfection of medical staff, operating room personnel entry and exit management, standard position and activity range, and aseptic dressing change operation. Through data granulation and granular reorganization and other means, the dataization and effective scoring of medical staff's operating behavior are realized, and effective indicators for corresponding diagnosis and treatment nodes for orthopedic surgical site infection prevention are constructed through behavioral research, and the aseptic operation behavior of medical staff and the operating room environment management are effectively standardized.
[0033] The database structure, cross-reference relationship between data, collection of key data, granular disassembly of data chain, granular reorganization and data coding in the present invention are finally formed by the inventor with the aseptic operation specification for preventing orthopedic surgical site infection as the core, and effectively integrating key technologies such as the Internet of Things, mobile communication, and data comparison reference. The core technology is the experience summary centered on aseptic technology and converted into computer network database language.
[0034] Beneficial effects: The clinical intelligent monitoring method for preventing orthopedic surgical site infection disclosed in the present invention has the following beneficial effects:
[0035] Through the technical solution of the present invention, the aseptic operation behaviors such as surgical hand disinfection and dressing change of medical personnel can be effectively regulated, which improves the scientificity and systematicness of surgical site infection prevention, thereby reducing the incidence of orthopedic surgical site infection and improving the patient's quality of life and medical safety.
