For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0048] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0049] The term "and / or" or "and / or" includes all combinations of any one or more of the associated listed items.

[0050] Figure 1 A schematic diagram of the principle of a central catheter-related bloodstream infection prevention and control management method provided in an embodiment of this specification, the method comprising:

[0051] S1 collects the patient's case information in real time;

[0052] S2 monitors whether the patient has risk indicators through the monitoring module 270 and generates monitoring results;

[0053] S3 combines the monitoring results and risk assessment strategy to identify patients at high risk of central catheter-related bloodstream infection and issue early warning reminders.

[0054] Many clinical databases have been established in different hospitals and institutions in my country. However, some clinical databases still use Excel spreadsheets or Access applications to save and analyze data. However, due to the complexity and variety of relevant clinical data, it is difficult to meet the actual needs of users.

[0055] Although more and more hospitals have built medical data monitoring platforms, most of them are single institutions with small scale and their related processes are not standardized. It is difficult to evaluate the quality and accuracy of monitoring data, compare data between regions, and evaluate the effectiveness of prevention and control measures.

[0056] Moreover, due to the failure to be user-centric during the platform construction process, the needs of target users were not fully considered, and scientific and standardized usability evaluation was not implemented before the platform was officially put into use, resulting in poor user experience and poor performance of some medical data monitoring platforms.

[0057] On this basis, due to the lack of an effective medical data monitoring platform, the global burden of healthcare-associated infections may be underestimated, including the occurrence of CLABSI (central line-associated bloodstream infection).

[0058] A domestic survey found that medical staff believed that the monitoring process related to CLABSI was not standardized, making it difficult to evaluate the quality and accuracy of the monitoring data. Moreover, the relevant monitoring could not compare data between regions, let alone evaluate the effectiveness of prevention and control measures.

[0059] Based on this, the present invention provides a prevention and control management system for central catheter-related bloodstream infection, such as Figure 2 As shown, the system includes:

[0060] Case management module 210, medical behavior review module 260 and monitoring module 270; wherein, the case management module 210 is used to manage case information in the case repository; the medical behavior review module 260 includes several review submodules, each of which is used to obtain the indicator value of the corresponding behavior indicator and record it in the case information; the monitoring module 270 includes: a basic indicator monitoring submodule and an early warning submodule; the basic indicator monitoring submodule is used to collect the patient's case information in real time; monitor whether the patient has risk indicators and generate monitoring results; the early warning submodule is used to combine the monitoring results and risk assessment strategies to determine high-risk patients and issue early warning reminders.

[0061] Specifically, Figure 3 As shown, a central catheter-related bloodstream infection prevention and control management system of the present invention comprises:

[0062] Information repository 200 , case management module 210 , visit management module 220 , supervision module 230 , data verification module 240 , project overview module 250 , medical care behavior review module 260 , and monitoring module 270 .

[0063] The information repository 200 includes: a case repository and a review policy repository.

[0064] Among them, the case repository is used to store all case information of all patients.

[0065] The review strategy repository is used to store various review strategies. The review strategy includes several ordered review information, including: behavioral indicators and compliance requirements.

[0066] In one embodiment of the present specification, the publicly available CLABSI prevention and control recommendations and catheter-related bloodstream infection prevention guidelines are regularly collected and retrieved to obtain a number of monitoring information. The monitoring information is deduplicated to obtain the original monitoring information, which is sent to decision makers and other users. After the decision makers determine the specific behavioral indicators and compliance requirements corresponding to the review strategy based on the original monitoring information, review information is constructed, and the review information includes: behavioral indicators and compliance requirements; the behavioral indicators are obtained, and each review information in the review strategy is sorted according to the execution order of the behavioral indicators.

[0067] Among them, the review policy repository stores the catheter placement review policy, maintenance review policy, and catheter removal review policy.

[0068] The case management module 210 is used to manage the case information in the case repository. Specifically, the case management module 210 includes:

[0069] The case creation submodule is used to add new case information to the case repository.

[0073] The case deletion submodule is used to delete case information from the case repository.

[0074] The case search submodule is used to search for case information that meets the requirements from the case repository.

[0075] In one embodiment of the present specification, the user identity and authority are verified. When the user is a clinical coordinator (CRC) or principal investigator (PI), the user is allowed to enter the patient name, hospitalization number, investigation time and investigator through the case creation submodule to automatically generate new case information.

[0076] The case management module in this manual can achieve systematic and standardized management of case information. This helps to improve the efficiency of information retrieval, ensure that medical staff can quickly and accurately obtain the required case information, and provide strong support for clinical decision-making. In addition, centralized management of case information can also help reduce information omissions or errors and improve the overall quality and safety of medical services.

[0077] The visit management module 220 is used by users such as the principal investigator (PI) and the clinical monitor (CRA) to manage the Clinical Research Form (CRF). Specifically, taking the patients in the ICU as an example, the Clinical Research Form (CRF) includes: the general information of the patients in the ICU, the central venous catheterization, the treatment, the risk score of critical illness, the patient's prognosis, the hospitalization expenses of the ICU, etc. In one embodiment of the present specification, the CRF is shown in Table 1:

[0078]

[0079]

[0080] (Table 1)

[0081] Among them, the central venous catheterization situation includes: the location of the catheterization, whether it is an emergency catheterization, whether it is multiple catheterizations, the culture status during the catheterization, and at least one of the laboratory indicators.

[0082] In one embodiment of the present specification, the details of each central venous catheter placement include: catheter placement time, personnel, whether the catheter was removed, and whether the catheter was retained for culture, specifically involving:

[0083] Physical signs during the catheterization period include body temperature, mean arterial pressure, chills, and hypotension.

[0084] Physical signs and results of culture, such as time, type, location and results of culture.

[0085] Laboratory indicators were collected and cultured within 24 hours, such as routine blood tests, blood sugar, liver and kidney function, C-reactive protein, procalcitonin, and interleukin.

[0086] Laboratory indicators are collected and cultured within 25-48 hours, such as blood routine, blood sugar, liver and kidney function, C-reactive protein, procalcitonin, and interleukin.

[0093] "ICU Cost Situation" in "Cost Situation" includes: ICU hospitalization expenses, various medical expenses, the patient's total medical expenses on the day of CVC placement, etc.

[0094] Specifically, the visit management module 220 includes:

[0095] The visit new submodule is used to add research information in the case information. The research information can be a clinical research information record table.

[0096] The visit modification submodule is used to modify the study information.

[0097] The visit entry submodule is used to enter patient information.

[0098] The visit freezing and unfreezing submodule is used to lock or unlock the research information. The visit freezing and unfreezing submodule includes: a visit freezing unit and a visit unfreezing unit. The visit freezing unit is used to lock the research information that is not locked, lock the modification authority of the research information, and avoid modification of the research information. The visit unfreezing unit is used to unlock the locked research information and restore the modification authority of the research information.

[0099] In one embodiment of the specification, a user such as a clinical coordinator (CRC) performs manual inspection of the data. If the data is incorrect, the supervisor module 230 raises a question to the principal investigator (PI) or the clinical coordinator (CRC), waiting for modification and / or reply. After the principal investigator (PI) or the clinical coordinator (CRC) confirms that it is correct, the visit is frozen; if the record needs to be modified again later, the data manager (DM) needs to unfreeze the visit. This module can track in real time whether a patient has or is suspected of having CLABSI, and take corresponding nursing measures for high-risk patients.

[0100] The visit deletion submodule is used to delete research information.

[0101] The supervision module 230 is used to combine manual inquiry and remote monitoring for real-time notification and closed-loop management. The inquiry content can be highlighted and counted. The number of newly created inquiries, the number of inquiries to be processed, the number of inquiries that have been replied, and the number of closed inquiries are recorded and displayed.

[0102] In one embodiment of the present specification, after a new case is successfully created, a visit list under the corresponding group is automatically generated to facilitate the principal investigator (PI) and clinical coordinator (CRC) to enter the information required for the CRF, and the page mark of the entry page of the current case is: Not entered. During the entry process, a field for logical verification is set to remind the user to enter according to the prompted rules; when a temporary save instruction is obtained, the entered content is saved, and the page mark of the entry page of the current case is updated to: Entering. When the entry completion instruction is obtained, the entry page of the case is marked, and the page mark of the entry page of the current case is updated to: Completed without verification of the original data (Source Data Verification, SDV).

[0103] After the case entry page is marked as completed, the page is monitored. The clinical monitor (CRA) can check the homepage according to the entry page. If there is no data problem on the verification page, it can be directly marked as "SDV"; if there is a data problem on the verification page, raise doubts and submit inquiries. When the inquiry is obtained, the inquiry content is sent to the principal investigator (PI) and clinical coordinator (CRC) corresponding to the case. After receiving the inquiry reply, the clinical monitor (CRA) verifies the modified data. When receiving the instruction to continue replying, the inquiry content is sent to the principal investigator (PI) and clinical coordinator (CRC) corresponding to the case; when receiving the instruction to close, the inquiry is closed. After all inquiries on the page are closed, check whether the current page is "SDV". When the user modifies the data, the status is updated to "Partial SDV completed", and the modified data is highlighted to facilitate monitoring of the page.

[0104] When the principal investigator (PI) and clinical coordinator (CRC) receive inquiries, they handle the pending queries, respond to the inquiries, and wait for the monitoring results of the clinical monitor (CRA).

[0105] The data verification module 240 is used to perform logic verification on the input data (including but not limited to the data input by the case management module 210 and the visit management module 220) to improve the accuracy of data input. The data verification module 240 includes:

[0106] The first verification submodule is used to verify the decimal point of the data;

[0107] The second verification submodule is used to verify the data range.

[0108] The third verification submodule is used to verify data consistency, for example, the admission date is earlier than the discharge date.

[0109] The fourth verification submodule is used to verify the uniqueness of data. For example, when creating case information, the corresponding number of each patient is a unique number.

[0110] The fifth verification submodule is used to verify completeness, for example, to verify whether the required items have been filled in.

[0111] The project overview module 250 displays and notifies the project progress. Specifically, the project overview module 250 includes:

[0112] The project progress display submodule is used to retrieve and display the project progress of the clinical trial. The project progress includes: case statistics progress, case entry progress, original data verification progress, inquiry progress, and the total number of catheter days in the ICU medical records of each hospital. Among them, the case statistics progress, case entry progress, original data verification progress, and inquiry progress can be viewed at any time, and the total number of catheter days in the ICU medical records of each hospital is automatically calculated and generated for easy comparison.

[0113] The message reminder submodule is used to push weekly and monthly reports of case rankings collected by ICUs of various hospitals based on user configuration.

[0114] The chart download submodule is used to download the charts involved in the project progress.

[0115] Central line catheters (CL) refer to catheters with their terminal ends close to the heart, including the aorta, pulmonary artery, inferior vena cava, brachiocephalic vein, internal jugular vein, subclavian vein, external iliac vein, femoral vein, and umbilical artery or vein in newborns.

[0116] Central Line Associated Blood Stream Infection (CLABSI) refers to a primary infection that occurs within 48 hours of a central venous catheter placement or before the catheter is removed and is unrelated to infection at other sites.

[0117] With the widespread use of central catheter technology, the incidence of central catheter-associated bloodstream infection (CLABSI) has also increased, affecting the treatment effect of patients, leading to increased hospitalization costs, prolonged hospitalization time and increased mortality. Therefore, preventing CLABSI is a key link in hospital infection prevention and control, and is crucial to ensuring patient safety.

[0118] In order to prevent central line-associated bloodstream infection (CLABSI), medical staff need to be trained to understand the risk factors and preventive measures of CLABSI; continuous quality improvement programs and monitoring are also required to ensure that the incidence of CLABSI is controlled and reduced. However, despite the above-mentioned preventive measures and training programs, the prevention and control of CLABSI still faces many challenges. On the one hand, the uneven operating skills and experience levels of medical staff may make it difficult to fully follow aseptic techniques and operating specifications in actual operations, thereby increasing the risk of infection. On the other hand, factors such as individual differences, immune status, and underlying diseases of patients may also affect the incidence of CLABSI.

[0119] Therefore, in order to further reduce the incidence of CLABSI and improve the quality of clinical nursing, a unified reference basis is provided for clinical nursing staff to prevent and control CLABSI. Preferably, a medical behavior review module 260 is also provided.

[0120] The medical behavior review module 260 includes a review information association submodule, a behavior analysis submodule, and several review submodules.

[0121] Specifically, the medical care behavior review module 260 includes: a review information association submodule, a catheter placement review submodule, a maintenance review submodule, a catheter removal review submodule, and a behavior analysis submodule.

[0122] The review information association submodule is used to obtain the review requirements of the reviewer; so that when clinical nurses provide care for patients with central catheters, the reviewers (nurses with review qualifications, including operating room nurses and intensive care unit nurses) can supervise the actual operational behavior of clinical nurses.

[0123] Specifically, the review requirements include: the patient number of the patient to be cared for and the current monitoring type. The monitoring type includes but is not limited to: CVC placement review, CVC extubation review, and CVC maintenance review.

[0124] In one embodiment of the present specification, when the current monitoring type is CVC catheterization review, the catheterization review submodule is called to display the catheterization behavior indicator to the user, and to obtain the indicator value of the catheterization behavior indicator.

[0125] When reviewing the CVC catheterization of medical care behavior, the catheterization review submodule retrieves the catheterization review strategy from the review strategy database, and the catheterization review strategy includes several catheterization review information. After retrieving the catheterization review strategy, the catheterization behavior indicator in the catheterization review information and the corresponding indicator value input area are displayed to the user through the catheterization review submodule; based on the user's filling or selection, the indicator value of the catheterization behavior indicator is obtained.

[0126] In one embodiment of the present specification, catheterization behavior indicators include but are not limited to: performing hand hygiene, selecting the most suitable puncture site, selecting puncture catheters and additional devices, using ultrasound to guide puncture, establishing a maximum sterile barrier, selecting a standardized skin disinfectant, standardizing skin disinfection, and standardizing catheter fixation.

[0128]

[0129] (Table 2)

[0130] In one embodiment of the present specification, when the current detection type is CVC extubation review, the extubation review submodule is called to display the extubation behavior indicator to the user, and to obtain the indicator value of the extubation behavior indicator.

[0131] When reviewing the CVC extubation of medical care behavior, the extubation review submodule retrieves the extubation review strategy from the review strategy database, and the extubation review strategy includes a number of extubation review information. After the extubation review strategy is retrieved, the extubation behavior index in the extubation review information and the corresponding index value input area are displayed to the user through the extubation review submodule; based on the user's entry or selection, the index value of the extubation behavior index is obtained.

[0132] In one embodiment of the present specification, the extubation behavior indicators include but are not limited to: performing hand hygiene, placing the extubated patient in a supine position, key point assessment before extubation, careful inspection of catheter integrity after extubation, retaining catheter tip culture, compression and bandaging, and Valsalva maneuver guidance.

[0133] In one embodiment of the present specification, the extubation review information is shown in Table 3.

[0151] The maintenance behavior indicators involved in "CVC indwelling status assessment" include: "2. Assessment of the catheter and its puncture site".

[0152] When clinical nurses perform relevant operations on the inserted central catheter, there is a strict medical operation sequence. Therefore, each behavioral indicator is arranged and displayed in sequence according to the execution order of the behavioral indicators in the monitoring strategy; so that the reviewer can input the indicator value of each behavioral indicator in sequence based on the actual operation behavior of the clinical nurse.

[0153] Specifically, the user is provided with indicator value options, including: conforming (Y), not conforming (N), and uncertain (NA).

[0154] Among them, compliance (Y) means that the clinical nurse's operation complies with the operation standards; non-compliance (N) means that the clinical nurse's operation does not comply with the operation standards.

[0155] When the user selects the review option of non-compliance (N), several reasons for non-compliance and one other option will pop up for the user to select. The user can select a specific reason option, or fill in the reason for being judged as non-compliant in the "other" option.

[0156] Uncertain (NA) means that it is uncertain whether the clinical nurse's operation complies with the operation standards; when the user selects the review option of Uncertain (NA), a "Not Involved" option and an "Other" option will pop up, and the user can fill in the options according to the actual situation; the user can choose "Not Involved" or fill in the reason for the judgment of Uncertain (NA) in "Other".

[0157] The indicator value option selected by the user is used as the indicator value of the behavior indicator.

[0158] The behavior analysis submodule is used to analyze the relationship between the behavior indicators and CLABSI. The behavior analysis submodule includes: a screening unit and an analysis unit.

[0159] The screening unit is used to screen out the medical care operation information of the target patient according to the preset screening conditions.

[0160] The preset screening conditions include: the entry time period of the behavior indicator, the detection type, and the behavior indicator.

[0161] The medical operation information includes: operation time, reviewer and review result. The operation time includes: one or more of the following: catheter placement time, maintenance time and catheter removal time.

[0162] In one embodiment of the present specification, the review result includes: the indicator values ​​of all behavioral indicators of the target patient that meet the preset screening conditions.

[0163] In another embodiment of the present specification, it is determined whether the index values ​​of all behavioral indicators of the target patient are all compliant (Y). If so, the review result of the target patient is compliant (Y); if not, it is determined whether among the index values ​​of all behavioral indicators of the target patient, there are only compliant (Y) and uncertain (NA). If so, the review result of the target patient is uncertain (NA); if not, the review result of the target patient is non-compliant (N).

[0164] The analysis unit obtains the data to be reviewed based on the review results in the medical care operation information of all target patients.

[0165] Among them, the data to be reviewed is the percentage of behaviors that meet the standards. The percentage of operations that meet the standards is =.

[0166] The medical behavior review module in this manual obtains the indicator values ​​of the corresponding behavior indicators through multiple review sub-modules and records them in the case information. This approach can achieve comprehensive and detailed monitoring of medical behavior, ensure that medical operations comply with regulations, and reduce the occurrence of medical errors and adverse events. At the same time, standardized behavioral indicator evaluation can help improve the professional quality and service quality of medical staff.

[0167] In this manual, users such as the principal investigator (PI) can view the overall information of medical and nursing behavior compliance, and the medical and nursing behavior is matched to each patient, so as to analyze the relationship between the behavior review indicators and CLABSI. In order to further clarify and monitor the central catheter-related bloodstream infection, facilitate the consistent quantitative evaluation and promote cross-hospital, cross-provincial and municipal data sharing and collaboration, conduct comprehensive and effective monitoring, evaluation and analysis of patients with tubes, and remind medical staff to intervene early, it also includes: monitoring module 270. Monitoring module 270 includes: basic indicator monitoring submodule and early warning submodule.

[0168] Among them, the basic indicator monitoring submodule is used to collect the patient's case information in real time; monitor whether the patient has risk indicators and generate monitoring results.

[0169] Specifically, risk indicators include: fever, chills, diabetes, APACHE II score exceeding the threshold, sepsis before catheterization, and key behaviors. Key behaviors include but are not limited to: emergency catheterization, multiple catheterizations, wrong catheterization sites, failure to fully follow the disinfection principle during operation, failure to fully follow hand hygiene during operation, and failure to cover the patient with a sterile sheet during catheterization.

[0170] The early warning submodule is used to combine monitoring results and risk assessment strategies to identify patients at high risk of central catheter-related bloodstream infection and provide early warning reminders.

[0171] In one embodiment of the present specification, the risk assessment strategy includes:

[0172] The number of days CVC is indwelling, body temperature (fever), hypotension, white blood cell count, C-reactive protein, procalcitonin, interleukin 6, and the use of antibiotics and immunosuppressants. When the monitoring indicators reach a dangerous value, the patient is identified as a high-risk patient for CLABSI, and the user is notified through red reminders, sound reminders, etc. For patients with emergency catheterization, a red reminder will also be displayed to remind the user to replace the CVC catheter within 48 hours.

[0173] Users input new / updated patient case information in real time. The system collects the patient case information entered by users in real time through the basic indicator monitoring submodule, and monitors whether the patients have risk indicators, which helps to detect changes in patients' conditions in a timely manner and gain valuable time for timely intervention and treatment.

[0174] Through the early warning sub-module, combined with monitoring results and risk assessment strategies, it is possible to accurately identify patients at high risk of central line-related bloodstream infection and provide early warning reminders, which helps medical staff take preventive measures in advance, reduce the incidence of infection, and ensure patient safety.

[0175] Moreover, the system of this manual makes it easy to compare the CLABSI rates of various medical institutions horizontally, avoiding large differences in the prevention and control standards of different medical institutions.

[0176] The user in this manual refers to the user of this system. The user's identity includes but is not limited to: decision maker, principal investigator (PI), clinical reviewer (CRA), clinical reviewer (CRC), and reviewer.
