Description

Technical Field

[0001] The present invention relates to the technical field of health management, and in particular to a health management system and method. Background Art

[0002] In today's era of globalization, population mobility is becoming increasingly frequent, the ecological environment is constantly changing, and the frequency of new infectious disease pathogens is on the rise. As a key place for medical treatment, hospitals are the first to face severe tests.

[0003] When a new virus spreads in the community, patients go to the hospital for medical treatment, and the virus they carry is very likely to remain in crowded and complex environments such as emergency rooms and wards. These new viruses often have unique transmission pathways and may break through traditional droplet and contact transmission modes, such as spreading through aerosols in ventilation systems, or spreading through contaminated medical equipment and environmental surfaces. At the same time, their living environment requirements are also more special. They may survive for a long time in low temperatures, high humidity, or on the surface of specific materials. Conventional disinfection methods and hygiene management processes are difficult to completely remove them.

[0004] This has put the hospital's original health management system into a dilemma. Health management needs to be dynamically analyzed and adjusted according to the spread stage of infectious diseases. Therefore, it is urgent to invent a health management system and method to solve the above problems. Summary of the invention

[0005] Technical issues resolved.

[0006] In view of the deficiencies of the prior art, the present invention provides a hygiene management system and method.

[0007] Technical solution.

[0008] In order to achieve the above-mentioned solution, the present invention provides the following technical solution: a health management system, including a data acquisition module, a model calculation module, a decision management module and a feedback adjustment module.

[0009] The data collection module is used to obtain information including but not limited to basic patient information, condition data, and medical staff scheduling.

[0010] The model calculation module is used to build an infectious disease transmission dynamics model and risk assessment. Hospital personnel are divided into four groups: susceptible S, infected I, recovered R, and latent E. The relationship between these four groups of people over time is described by a group of differential equations: : represents the rate at which susceptible people turn into infected or latent people, where is the propagation coefficient, , The value range is between, is the total number of people in the hospital, : The rate at which latents are generated minus the rate at which latents are converted into infected people, where is the conversion rate of lurkers, , The value range is between, : The rate of increase of infected people minus the rate of recovery of infected people, where is the recovery rate, , The value range is between, : The rate of increase of recovered patients, risk value , where , , is the weight of each indicator, + + =1, D is the patient density index of the ward, F is the frequency index of contact between medical staff and patients, and A is the regional ventilation index.

[0011] The decision management module is used to change the response strategy in real time according to the risk value.

[0012] The feedback adjustment module tracks and evaluates the effects of health management measures after implementation and adjusts strategies in real time.

[0013] Preferably, the risk assessment calculates the risk value by considering the patient density in the ward, the frequency of contact between medical staff and patients, and the ventilation conditions in the area. The calculation formula for the patient density index in the ward is: , is the number of patients in the ward, is the ward volume, and the calculation formula for the frequency of contact between medical staff and patients is: , The number of contacts between medical staff and patients at different times. To count the number of time periods, the calculation formula for the regional ventilation index is: , The air exchange rate of the ventilation system.

[0014] Preferably, the Rapidly rising, and When the value is 1.5, it indicates that the infectious disease is in a rapid spreading stage. Maintain a relatively stable value, and 1 When the value is 1.5, it indicates that the infectious disease is in a stable transmission stage. gradually decreases, and 1 o'clock indicates that the infectious disease is in the stage of slowing spread.

[0015] A health management method of the system includes the following steps: Step 1: data collection and preprocessing, including sensor data integration and medical information fusion.

[0016] Step 2: Model-driven risk assessment and stage determination, including analysis of infectious disease transmission dynamics, quantification of risk assessment indicators and weight optimization, and accurate determination of transmission stages.

[0017] Step three: Implementation of dynamic health management strategy, targeting the rapid transmission stage, stable transmission stage and transmission mitigation stage, and differentiated implementation from the perspective of refined disinfection management, hierarchical personnel protection and coordinated allocation of medical resources. In the rapid transmission stage, high-, medium- and low-risk areas need to be disinfected once every 2 hours, once every 3 hours, and 4-6 times a day, respectively. Medical staff wear high-level and high-frequency replacement of protective equipment, urgently expand beds, and reserve a large amount of medical resources; in the stable transmission stage, the disinfection frequency of high-, medium- and low-risk areas is adjusted to once every 4 hours, once every 6 hours, and 2-3 times a day. The protection of medical staff is moderately reduced and the replacement frequency is slowed down, and beds and resource supplements are reasonably adjusted; in the transmission mitigation stage, the disinfection frequency of high-, medium- and low-risk areas is reduced to 3-4 times a day, 2-3 times a day, and 1-2 times a day. The protection of medical staff is further simplified, and medical resources and personnel allocation are gradually restored to normal.

[0018] Step 4: Continuous feedback and optimization adjustments, including data monitoring and feedback collection, model and strategy optimization and updating.

[0019] Preferably, the dynamic health management strategy is implemented in the rapid spread stage. In high-risk areas, chlorine-containing disinfectants with an effective chlorine content of 1000mg / L-2000mg / L and 0.5% concentration of peracetic acid are used to thoroughly wipe the surface of objects and spray the ground. The air is continuously operated with an ultraviolet circulating air disinfector, and the ventilation is 10-15 times / hour. In medium-risk areas, chlorine-containing disinfectants with an effective chlorine content of 500mg / L-1000mg / L are used to focus on disinfecting areas where patients frequently contact, and the air is irradiated with ultraviolet lamps for 30 minutes / time, using a high-power spray disinfector; in low-risk areas, disinfection is carried out 4-6 times a day, using chlorine-containing disinfectants with an effective chlorine content of 250mg / L-500mg / L, focusing on disinfecting high-frequency contact areas, and using a small portable disinfection spray bottle.

[0020] Preferably, the dynamic hygiene management strategy is implemented in the stable transmission stage. In high-risk areas, chlorine-containing disinfectants with an effective chlorine content of 500mg / L-800mg / L are used to strengthen the disinfection of ward toilets; in medium-risk areas, chlorine-containing disinfectants with an effective chlorine content of 300mg / L-500mg / L are used to focus on disinfecting the surface of medical equipment, using a spray disinfector in combination with disinfectant wipes; in low-risk areas, chlorine-containing disinfectants with an effective chlorine content of 100mg / L-250mg / L are used, and attention is paid to ventilation, using conventional cleaning tools as the main method.

[0021] Preferably, the dynamic hygiene management strategy is implemented in the transmission mitigation stage. In high-risk areas, chlorine-containing disinfectants with an effective chlorine content of 200 mg / L-500 mg / L are used, with a focus on terminal disinfection; in medium-risk areas, chlorine-containing disinfectants with an effective chlorine content of 100 mg / L-200 mg / L are used for routine disinfection of major public areas and medical equipment, and the use of large equipment is reduced; in low-risk areas, chlorine-containing disinfectants with an effective chlorine content of 50 mg / L-100 mg / L are used, and daily maintenance is emphasized, using daily cleaning tools.

[0022] Beneficial Effects

[0023] Compared with the prior art, the present invention provides a health management system and method, which has the following beneficial effects:

[0024] 1. The health management system uses real-time data to drive model and strategy updates in infectious disease prevention and control. For example, when an epidemic breaks out, it quickly strengthens disinfection in high-risk areas and personnel protection to curb transmission. As the epidemic eases, it accurately reduces the intensity of prevention and control, rationally allocates resources, avoids waste, and continuously provides feedback and optimization to ensure that the system is closely aligned with reality, accurately responds to the evolution of infectious diseases, improves the efficiency of hospital emergency and normal management, reduces infection risks, ensures the stability of medical order, and builds a solid line of defense for hospitals to efficiently respond to the threat of new infectious diseases, effectively protecting the health and safety of doctors and patients.

[0025] 2. Through continuous data monitoring and analysis, this health management method can keenly capture the changing trends of the spread of infectious diseases in hospitals. In the early stage of rapid spread of the epidemic, it can quickly strengthen prevention and control measures, disinfect frequently, upgrade personnel protection and urgently allocate resources to effectively curb the spread of the epidemic. As the epidemic enters a stable or slowing stage, it can accurately and appropriately relax control, reasonably allocate resources and avoid excessive investment. This dynamic adjustment mechanism always ensures that the management strategy is closely aligned with the actual epidemic situation, greatly improving the flexibility and accuracy of the hospital's response to infectious diseases, and effectively ensuring the safety of the medical environment and the efficient operation of medical services.

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.

[0029] See also Figure 1-2 The present invention proposes a health management system and method, including

[0030] 1. Health Management System

[0031] 1. Data acquisition module: It is composed of various sensors distributed in various areas of the hospital, such as personnel positioning sensors, temperature and humidity sensors, air quality sensors, ventilation flow sensors, etc. At the same time, it is connected to the hospital information management system (HIS), electronic medical record system (EMR), etc. to obtain basic information of patients, disease data, medical staff scheduling and other information. These data will provide a basis for subsequent model calculation and analysis.

[0032] 2. Model calculation module: building infectious disease transmission dynamics model and risk assessment

[0033] The hospital personnel are divided into four groups: susceptible people S, infected people I, recovered people R, and latent people E, and the model is constructed:

[0034] : Indicates the rate at which susceptible people turn into infected or latent people, where is the propagation coefficient, , The value range is between, is the total number of people in the hospital.

[0035] : The rate at which Lurkers are generated minus the rate at which Lurkers are converted to Infected, is the conversion rate of lurkers, , The value range is between.

[0036] : The rate at which infected people increase minus the rate at which infected people recover, is the recovery rate, , The value range is between.

[0037] : The rate at which the number of recovered patients increases.

[0038] The risk value is calculated by considering the patient density in the ward, the frequency of contact between medical staff and patients, and the ventilation conditions of the area.

[0039] Ward patient density indicators: , is the number of patients in the ward, The volume of the ward.

[0040] Indicators of frequency of contact between medical staff and patients: , The number of contacts between medical staff and patients at different times. is the number of statistical time periods.

[0041] Regional ventilation indicators: , The air exchange rate of the ventilation system.

[0042] Risk Assessment Formula: Value at Risk ,in , , The weight of each indicator is determined based on the experts' scores on the importance of three factors: patient density, frequency of contact between medical staff and patients, and regional ventilation conditions. + + =1.

[0043] 3. Decision management module: According to the output results of the model calculation layer, it is divided into rapid propagation stage, stable propagation stage and propagation slowdown stage.

[0044] when Rapidly rising, and When the value is 1.5, it indicates that the infectious disease is in the rapid spread stage. At this time, the number of people infected in the hospital is increasing rapidly and the scope of transmission is expanding.

[0045] when Maintain a relatively stable value, and 1 1.5 indicates that the infectious disease is in a stable transmission stage. At this time, although the hospital infection is still developing, the transmission speed has slowed down and is in a relatively controllable state.

[0046] when gradually decreases, and 1, indicating that the infectious disease is in the stage of slowing down its spread. At this time, the spread of the infectious disease has been effectively controlled and the number of infections has begun to gradually decline.

[0047] Automatically adjust the disinfection plan based on the real-time risk values ​​of different areas.

[0048] Dynamically adjust personnel protection levels based on the risk levels of different areas and the nature of personnel’s work.

[0049] Medical resources are dynamically allocated based on the infection trends predicted by the infectious disease transmission dynamics model and the actual needs of each department. When it is predicted that the number of patients with a certain type of infectious disease will increase, the corresponding medicines, medical equipment and other materials will be allocated to the relevant departments in advance, and the work tasks and shifts of medical staff will be reasonably arranged to ensure the normal development of medical services.

[0050] 4. Feedback adjustment module: By tracking and evaluating the effects of health management measures after implementation, relevant feedback data is collected, such as changes in the number of infected people, environmental microbial monitoring data, etc. These feedback data are input into the model calculation layer again to optimize and adjust the model parameters and the weights of the risk assessment algorithm, so that the system can adapt to the actual situation more accurately and achieve dynamic self-optimization.

[0051] 2. Hygiene management methods

[0052] 1. Data collection and preprocessing

[0053] 1. Sensor data integration: Use personnel positioning sensors to accurately grasp the movement trajectory and residence time of personnel in the hospital, especially in key areas such as wards, outpatient clinics, and operating rooms. Temperature and humidity sensors work together with air quality sensors to monitor environmental temperature and humidity and air quality parameters (such as PM2.5, harmful gas concentration, etc.) in real time. Ventilation flow sensors continuously monitor ventilation conditions in each area to ensure that the ventilation system operates normally and the ventilation volume meets the standards.

[0054] 2. Medical information integration: Deeply integrate HIS and EMR system data to not only obtain basic patient information and dynamic changes in the condition, but also analyze the relationship between disease diagnosis, treatment plans and the risk of infectious disease transmission. At the same time, detailed records of medical staff scheduling information, including working hours, rotations in different departments, and specific time periods of contact with patients, provide comprehensive data support for subsequent risk assessment.

[0055] 2. Model-driven risk assessment and stage determination

[0056] 1. Analysis of infectious disease transmission dynamics: Pay close attention to the changing trends in the number of susceptible people (S), infected people (I), recovered people (R) and latent people (E), and accurately calculate the transmission coefficient ( β), taking into account the social distance of people in the hospital, the implementation of protective measures and the characteristics of pathogen transmission; determining the latent conversion rate ( σ ) and recovery rate ( γ ), through case studies of different types of infectious diseases and follow-up analysis of actual cases in our hospital, combined with clinical diagnosis data and treatment effect evaluation, we obtained practical values ​​to ensure that the model accurately reflects the spread of infectious diseases.

[0057] 2. Quantification of risk assessment indicators and optimization of weights: Accurately calculate the ward patient density index (D), the medical staff and patient contact frequency index (F) and the regional ventilation condition index (A). In terms of ward patient density, the patient's activity range and the possibility of personnel gathering are considered based on the actual layout of the ward and the use of beds; the frequency of contact between medical staff and patients is based on the scheduling information and actual operating procedures, and the number of contacts in different medical operations (such as ward rounds, nursing, surgery, etc.) is counted; the regional ventilation condition is evaluated in combination with the ventilation system design parameters and actual operating effects. Using the analytic hierarchy process (AHP) or fuzzy comprehensive evaluation method, experts from multiple fields (infectious diseases, hospital management, environmental sanitation, etc.) are invited to score the importance of each indicator, construct and solve the judgment matrix, and determine the weight ( , , ), and review and update the weights regularly to adapt to changes in hospital environment and infectious disease characteristics.

[0058] 3. Accurate determination of the spread stage: set dynamic thresholds and time windows, and monitor the changes in R values ​​in real time. 1.5, immediately trigger the emergency response mechanism; in the stable transmission stage, when stable and 1 1.5, continue to monitor and fine-tune management strategies; in the stage of transmission mitigation, if it is reduced and 1.
