Description

Technical Field

[0001] The present invention relates to the field of medical emergency technology, and in particular to a method for early identification of emergency sepsis patients using NEWS combined with CRT. Background Art

[0002] Sepsis is a systemic inflammatory response syndrome caused by infection, which often leads to multiple organ dysfunction. If not identified and treated in time, it may progress to septic shock and even cause death. Sepsis is one of the most common critical illnesses in emergency departments and intensive care units (ICUs) worldwide, with a high morbidity and mortality rate. According to global statistics, sepsis affects tens of millions of patients each year, and about one-third of sepsis patients will eventually die from the disease. Therefore, how to identify sepsis early in the emergency setting, intervene quickly and treat it is crucial to improve patient survival.

[0003] At present, the diagnosis of sepsis mainly relies on clinical symptoms, laboratory tests and scoring systems. However, existing diagnostic tools such as the rapid sequential organ failure assessment (qSOFA) and the systemic inflammatory response syndrome (SI RS) score have problems with insufficient sensitivity and specificity. qSOFA is widely used due to its simplicity, but its sensitivity is low in predicting high-risk patients with sepsis, especially for patients with occult disease, which is easy to miss. In addition, the clinical symptoms of sepsis are diverse and develop rapidly, and the patient's systemic circulation and microcirculation status are often inconsistent, which makes it difficult for a single evaluation method to fully reflect the patient's condition.

[0004] The early warning score (NEWS) is a condition assessment tool used in the emergency department. It can effectively predict the risk of worsening of the patient's condition by evaluating the patient's respiratory rate, blood oxygen saturation, blood pressure, heart rate, body temperature and consciousness. Although NEWS has shown good predictive ability in the emergency environment, it is insufficient in assessing the microcirculatory function of patients with sepsis. Microcirculatory disorder is an important sign of early organ function damage in sepsis, and NEWS alone cannot fully reflect the patient's microcirculatory status.

[0005] Capillary refill time (CRT) is a simple and rapid bedside tool for assessing microcirculatory status. By pressing the patient's nail bed and observing the time for color recovery, CRT can reflect the perfusion of microcirculation. The CRT measurement method is easy to operate and non-invasive, and is particularly suitable for emergency environments. However, it is difficult to provide a comprehensive sepsis assessment relying solely on CRT measurement.

[0006] In view of the shortcomings of existing technologies, a method of NEWS combined with CRT for early identification of emergency sepsis patients is provided. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides a method for early identification of emergency sepsis patients using NEWS combined with CRT, which solves the problem of rapid and accurate early identification of sepsis patients by jointly evaluating the systemic circulation and microcirculation status in an emergency environment.

[0008] To achieve the above objectives, the present invention is implemented by the following technical scheme: NEWS combined with CRT is used for the early identification method of emergency sepsis patients, comprising the following steps:

[0009] When the patient enters the emergency department, the patient's physiological parameters are collected, including respiratory rate, heart rate, systolic blood pressure, body temperature, blood oxygen saturation and consciousness state;

[0010] The UK National Early Warning Score (NEWS) is calculated based on physiological parameters. When the NEWS score is greater than 4.07, it indicates that the patient is at risk of sepsis.

[0011] The capillary refill time (CRT) of the patient was measured. During the measurement, the patient's fingers were raised to the same level as the heart, and the nail bed was pressed with the fingers for 5 seconds, and the CRT time was recorded.

[0012] When the CRT time is greater than 3.71 seconds, it indicates that the patient has microcirculatory disorders;

[0013] The NEWS score and CRT results were jointly analyzed, and when the NEWS score was greater than 4.07 and the CRT time was greater than 3.71 seconds, the patient was identified as a high-risk patient for sepsis;

[0014] Introducing automated CRT measurement devices and intelligent monitoring systems, and integrating NEWS scores and automated CRT data into the hospital information system (HIS) to achieve intelligent sepsis risk assessment and early warning;

[0015] Early intervention for sepsis is performed on high-risk patients based on the identification results.

[0016] Preferably, the physiological parameters are collected by automatic monitoring equipment and recorded in real time to the hospital information system HIS.

[0017] Preferably, the capillary refill time CRT is measured by an automated CRT measuring device, which includes an optical sensor and a pressure sensing device, and can automatically record the time it takes for the nail bed color to recover after pressing.

[0018] Preferably, the measurement data of the automated CRT measurement device is wirelessly transmitted to a hospital information system and integrated with the NEWS score into an intelligent analysis system for sepsis identification.

[0019] Preferably, the identification method comprises the following steps:

[0020] According to the NEWS score and CRT measurement results, patients were divided into high-risk, intermediate-risk, and low-risk groups;

[0021] The sepsis intervention process was initiated for patients in the high-risk group, including antibiotic treatment, fluid resuscitation, and monitoring of organ function.

[0022] Preferably, the identification process includes an automated algorithm that automatically determines the patient's sepsis risk by analyzing the combined data of NEWS and CRT, and issues an early warning prompt.

[0023] Preferably, the CRT measurement includes multiple repeated measurements, and in patients with rapidly changing conditions or critical states, the measurement is repeated every 2 hours, and the patient's condition is dynamically evaluated.

[0024] Preferably, the method is suitable for screening for sepsis in patients with acute infection or suspected infection in the emergency department, and is combined with blood tests (including procalcitonin PCT and C-reactive protein CRP) to further improve the accuracy of identification.

[0025] Preferably, the system generates a chart showing the patient's vital signs and condition change trends based on the recognition results for medical staff to refer to in order to decide whether intensive treatment or transfer to the ICU is needed.

[0026] Preferably, the intervention measures also include closely monitoring the patient's urine volume, blood lactate level and renal function to comprehensively assess the patient's organ function and adjust the treatment plan based on these indicators.

[0027] The present invention provides a method for early identification of emergency sepsis patients using NEWS combined with CRT. It has the following beneficial effects:

[0028] 1. The present invention combines the early warning score (NEWS) with the capillary refill time (CRT) to simultaneously evaluate the patient's systemic circulation and microcirculation status, thereby improving the accuracy of early identification of sepsis. Compared with the evaluation method of a single indicator, NEWS combined with CRT can more comprehensively reflect the patient's condition and reduce misdiagnosis and missed diagnosis, especially in the early stages when the condition is relatively hidden.

[0029] 2. The present invention introduces CRT measurement to supplement the deficiencies of traditional NEWS scoring in evaluating microcirculatory function. As a rapid, non-invasive bedside assessment tool, CRT can effectively reflect the microcirculatory disorders in the early stages of sepsis, making the identification of patients more comprehensive and accurate. By combining CRT measurement, patients with microcirculatory disorders can be identified, thereby detecting potential crises even when the systemic circulation is normal.

[0030] 3. By introducing automated CRT measurement equipment and intelligent analysis systems, the present invention can automatically analyze NEWS and CRT data, determine sepsis risk in real time, and issue early warning prompts. This intelligent system can assist medical staff in quickly determining whether patients need emergency intervention, improve the system's ability to identify sepsis, reduce human operation errors, and accelerate the efficiency of clinical decision-making. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 The figure is a flow chart of the method of the present invention. DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the specification 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.

[0033] Please see attached Figure 1 The embodiment of the present invention provides a method for early identification of emergency sepsis patients using NEWS combined with CRT, comprising the following steps:

[0034] When the patient enters the emergency department, the patient's physiological parameters are collected, including respiratory rate, heart rate, systolic blood pressure, body temperature, blood oxygen saturation and consciousness state;

[0035] The UK National Early Warning Score (NEWS) is calculated based on physiological parameters. When the NEWS score is greater than 4.07, it indicates that the patient is at risk of sepsis.

[0036] The capillary refill time (CRT) of the patient was measured. During the measurement, the patient's fingers were raised to the same level as the heart, and the nail bed was pressed with the fingers for 5 seconds, and the CRT time was recorded.

[0037] When the CRT time is greater than 3.71 seconds, it indicates that the patient has microcirculatory disorders;

[0038] The NEWS score and CRT results were jointly analyzed, and when the NEWS score was greater than 4.07 and the CRT time was greater than 3.71 seconds, the patient was identified as a high-risk patient for sepsis;

[0039] Introducing automated CRT measurement devices and intelligent monitoring systems, and integrating NEWS scores and automated CRT data into the hospital information system (HIS) to achieve intelligent sepsis risk assessment and early warning;

[0040] Early intervention for sepsis is performed on high-risk patients based on the identification results.

[0041] The physiological parameters are collected through automatic monitoring equipment and recorded in real time to the hospital information system HIS.

[0042] Specifically, the patient's physiological parameters, including respiratory rate, heart rate, systolic blood pressure, body temperature, blood oxygen saturation and consciousness state, are collected through automatic monitoring equipment, and the data are recorded in real time to the hospital information system (HIS); then, the UK National Early Warning Score (NEWS) is calculated based on the collected physiological parameters. When the NEWS score is greater than 4.07, it indicates that the patient may be at risk of sepsis; then the patient's capillary refill time (CRT) is measured. During the measurement, the patient's fingers are raised to the same level as the heart, and the patient's nail bed is pressed with the fingers for 5 seconds and then released. The time required for the nail bed to return to red is recorded. If the CRT time is greater than 3.71 seconds, it indicates that the patient is at risk of sepsis. In microcirculation disorders; the NEWS score and CRT results are jointly analyzed. When the NEWS score is greater than 4.07 and the CRT time is greater than 3.71 seconds, the patient is identified as a high-risk patient for sepsis; then an automated CRT measurement device is introduced to automatically record and upload the CRT measurement results to the HIS. The system integrates the NEWS score with the CRT data, and uses an intelligent algorithm to assess and warn of sepsis risk, automatically generating a sepsis risk assessment report for the patient; based on the identification results, early intervention is performed on high-risk patients, including rapid antibiotic treatment, fluid resuscitation, and further monitoring of organ function to ensure that patients receive timely treatment before their condition worsens.

[0043] The capillary refill time CRT is measured by an automated CRT measuring device, which includes an optical sensor and a pressure sensing device, and can automatically record the time it takes for the nail bed color to recover after pressing.

[0044] The measurement data of the automated CRT measurement device is wirelessly transmitted to the hospital information system and integrated with the NEWS score in an intelligent analysis system for sepsis identification.

[0045] The identification method comprises the following steps:

[0046] According to the NEWS score and CRT measurement results, patients were divided into high-risk, intermediate-risk, and low-risk groups;

[0047] The sepsis intervention process was initiated for patients in the high-risk group, including antibiotic treatment, fluid resuscitation, and monitoring of organ function.

[0048] Specifically, when measuring the capillary refill time (CRT) of patients, an automated CRT measuring device is used. The device consists of an optical sensor and a pressure-sensing device. The optical sensor is used to detect the color change of the patient's nail bed, and the pressure-sensing device is used to standardize the pressing process, ensure that the pressing lasts for 5 seconds, and automatically record the time for the nail bed color to recover after pressing. The measurement results are uploaded to the hospital information system (HIS) in real time through wireless transmission, and integrated into the intelligent analysis system with the NEWS score. The system automatically performs data analysis and sepsis risk assessment. The intelligent analysis system divides patients into high-risk, medium-risk, and low-risk groups based on the NEWS score and CRT results. The specific basis is: when the NEWS score is greater than 4.07 and the CRT time is greater than 3.71 seconds, the patient is identified as a high-risk group; if only one indicator is abnormal, it is classified as a medium-risk group, and if both are normal, it is a low-risk group. For patients in the high-risk group, the system immediately initiates the sepsis intervention process, which includes rapid administration of broad-spectrum antibiotics, fluid resuscitation to maintain hemodynamic stability, and close monitoring of the patient's organ function, such as urine volume, blood lactate level, and renal function. All treatment processes are automatically tracked by the system to ensure that patients receive timely and accurate intervention and treatment.

[0049] The identification process includes an automated algorithm that automatically determines the patient's sepsis risk by analyzing the combined data of NEWS and CRT, and issues an early warning prompt.

[0050] The CRT measurement includes multiple repeated measurements. In patients whose condition changes rapidly or is in a critical state, the measurement is repeated every 2 hours, and the patient's condition is dynamically evaluated.

[0051] The method is suitable for screening sepsis in patients with acute infection or suspected infection in the emergency department, and is combined with blood tests (including procalcitonin PCT and C-reactive protein CRP) to further improve the accuracy of identification.

[0052] The system generates a chart of the patient's vital signs and condition change trends based on the recognition results for medical staff to refer to in order to decide whether intensive treatment or transfer to the ICU is needed.

[0053] The intervention measures also include close monitoring of the patient's urine volume, blood lactate level and renal function to comprehensively assess the patient's organ function and adjust the treatment plan based on these indicators.

[0054] Specifically, an automated algorithm is introduced in the identification process. The algorithm automatically determines the risk of sepsis by analyzing the patient's NEWS score and CRT measurement data, and automatically issues an early warning when the risk increases. For patients whose condition changes rapidly or is in a critical state, CRT measurement is repeated every 2 hours, and the patient's condition is dynamically evaluated through an intelligent monitoring system. This method is particularly suitable for sepsis screening in patients with acute infection or suspected infection in the emergency department. It can be combined with blood test indicators such as procalcitonin (PCT) and C-reactive protein (CRP) to further improve the accuracy of sepsis identification. The system generates a trend chart of the patient's vital signs and condition changes based on the identification results for reference by medical staff to decide whether to strengthen treatment or transfer the patient to the ICU. For patients with sepsis who have been identified as high-risk, the system automatically initiates intervention measures, including close monitoring of the patient's urine volume, blood lactate level, and renal function, to comprehensively evaluate the organ function status, and adjust the treatment plan based on these physiological indicators to ensure timely intervention and optimize the patient's treatment effect.

[0055] Step 1: Collection of physiological parameters

[0056] After the patient is admitted to the hospital, the basic physiological parameters are first collected by the nursing staff or automatic monitoring equipment. These parameters are used to calculate the NEWS score and make a preliminary assessment of the risk of sepsis. Specific parameters include:

[0057] Respiratory rate (times / minute): The patient's respiratory rate is observed and recorded by bedside monitoring equipment or nursing staff;

[0058] Heart rate (beats / minute): measured by electronic monitoring equipment or manual pulse;

[0059] Systolic blood pressure (mmHg): measured using an electronic sphygmomanometer;

[0060] Body temperature (℃): measured by ear thermometer or axillary thermometer;

[0061] Blood oxygen saturation (SpO2, %): obtained by finger-clip pulse oximeter;

[0062] Consciousness: Consciousness was assessed using the AVPU scoring criteria.

[0063] The above data are recorded through the hospital information system (HIS) or bedside monitoring system for subsequent NEWS score calculation and CRT measurement.

[0064] Step 2: Calculation of NEWS score

[0065] Based on the patient's physiological data, the UK National Early Warning Score (NEWS) standard is used for scoring. The specific scoring criteria are as follows:

[0066] Respiratory rate:

[0067] <8 times / minute: 3 points;

[0068] 8-11 times / minute: 1 point;

[0069] 12-20 times / minute: 0 points;

[0070] 21-24 times / minute: 2 points;

[0071] 24 times / minute: 3 minutes.

[0072] Systolic blood pressure:

[0073] <90 mmHg: 3 points;

[0074] 91-100mmHg: 2 points;

[0075] 101-110 mmHg: 1 point;

[0076] 111-219 mmHg: 0 points;

[0077] 220 mmHg: 3 points.

[0078] Heart rate:

[0079] <40 beats / minute: 3 points;

[0080] 41-50 times / minute: 1 point;

[0081] 51-90 times / minute: 0 points;

[0082] 91-110 beats / minute: 1 point;

[0083] 111-130 times / minute: 2 points;

[0084] 130 times / minute: 3 minutes.

[0085] body temperature:

[0086] <35℃: 3 minutes;

[0087] 35-38℃: 0 minutes;

[0088] 38.1-39℃: 1 minute;

[0089] 39℃: 2 minutes.

[0090] Blood oxygen saturation:

[0091] <91%: 3 points;

[0092] 91%-93%: 2 points;

[0093] 94%-95%: 1 point;

[0094] 96%: 0 points.

[0095] State of consciousness:

[0096] A (awake): 0 points;

[0097] V (language awakening): 3 points;

[0098] P (pain arousal): 3 points;

[0099] U (no response): 3 points.

[0100] Nurses add up the scores of various physiological parameters to get the total NEWS score. When the NEWS score is greater than 4.07, it indicates that the patient's systemic circulatory function may be affected and there is a risk of sepsis.

[0101] Step 3: Capillary refill time (CRT) measurement

[0102] After the NEWS score is completed, CRT measurement is performed immediately to evaluate the patient's microcirculatory function. The steps are as follows:

[0103] The patient lies supine or sits, and the nurse raises the patient's right hand to the level of the heart;

[0104] The nurse applies pressure to the patient's nail bed with their fingers for 5 seconds;

[0105] After releasing the pressure, use a stopwatch to record the time required for the nail bed color to return to red, which is the CRT.

[0106] CRT determination criteria:

[0107] If the CRT time is greater than 3.71 seconds, it indicates that the patient has microcirculation disorder, which is one of the early signs of sepsis.

[0108] Step 4: NEWS and CRT Joint Evaluation

[0109] By combining NEWS scores with CRT results, it is possible to comprehensively judge whether the patient is at high risk of sepsis:

[0110] High-risk patients: If the NEWS score is greater than 4.07 and the CRT time is greater than 3.71 seconds, it indicates that the patient has problems with both systemic circulation and microcirculation. Sepsis should be highly suspected and intervention should be initiated immediately.

[0111] Medium-risk patients: If NEWS or CRT exceeds the standard, the patient may be in the early stage of sepsis and needs to be further combined with other tests (such as procalcitonin PCT, C-reactive protein CRP, etc.) for comprehensive judgment.

[0112] Low-risk patients: If NEWS and CRT are both within the normal range, the patient's risk of sepsis is low, but close observation is still required.

[0113] Step 5: Intervention and clinical management

[0114] For high-risk patients, early intervention for sepsis should be initiated immediately. Specific measures include:

[0115] Antibiotic treatment: Broad-spectrum antibiotics are given within 1 hour to cover possible sources of infection;

[0116] Fluid resuscitation: fluid resuscitation is given according to the patient's blood pressure, urine volume, etc. to maintain hemodynamic stability;

[0117] Organ function monitoring: Closely monitor the functions of the heart, kidneys, lungs and other organs, especially blood lactate levels and urine volume, and adjust treatment plans at any time.

[0118] For patients at medium or low risk, continuous dynamic monitoring should be performed, NEWS and CRT should be retested regularly, and a more aggressive intervention plan should be upgraded if necessary.

[0119] Automation equipment and intelligent analysis

[0120] Automated CRT measurement equipment

[0121] In order to improve the accuracy of measurement and reduce human error, the present invention proposes the use of an automated CRT measurement device. The device includes an optical sensor and a pressure sensing device, which can standardize the pressing process and automatically record the CRT time. The device uploads the measurement data to the hospital information system (HIS) via wireless transmission and integrates it with the NEWS score data.

[0122] Intelligent analysis and early warning system

[0123] Through the integration of automated CRT equipment and NEWS score data in the hospital information system, the patient's sepsis risk is automatically calculated using intelligent algorithms, and real-time vital signs and condition change trend charts are generated. System functions include:

[0124] Real-time warning: When the patient's NEWS score and CRT exceed the threshold at the same time, the system automatically issues a high-risk sepsis warning and notifies medical staff to take intervention measures.

[0125] Dynamic trend chart generation: The system generates dynamic trend charts of patients' vital signs, NEWS scores and CRT time in real time to help clinicians observe changes in the condition and assist in decision-making.

[0126] Implementation effect and clinical application

[0127] The present invention significantly improves the early identification rate of emergency sepsis patients by combining NEWS with CRT, especially when the disease changes are relatively hidden, and effectively reduces the missed diagnosis rate through comprehensive evaluation of microcirculation and systemic circulation. The method is simple and fast, and is particularly suitable for emergency departments and other emergency medical environments.

[0128] Sensitivity and specificity: The combined use of NEWS and CRT can improve both the sensitivity and specificity of identification, complete the initial screening in a shorter time, and ensure timely intervention.

[0129] Automation and intelligence: Through automated equipment and intelligent analysis systems, manual operation errors are reduced and the efficiency and accuracy of sepsis identification are improved. It is suitable for emergency environments with limited medical resources.

[0130] Clinical decision support: Intelligent disease trend charts provide doctors with more intuitive information about the patient's disease progression, ensuring that intervention decisions can be made quickly in complex clinical environments.

[0131] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
