Description

Technical Field

[0001] The present application relates to the technical field of patient risk assessment, and in particular to a VTE risk assessment system, equipment, medium and product for critically ill surgical patients. Background Art

[0002] Surgery patients with critical illness usually refer to patients with serious diseases that are life-threatening or affect the function of major organs. The characteristics of their condition are mainly reflected in the complex etiology, rapid progression of the disease, and multiple changes in the condition. Common surgical critical illnesses include venous thromboembolism (VTE), pulmonary embolism, cardiac embolism, cerebral embolism, multiple organ dysfunction syndrome (MODS), acute respiratory distress syndrome (ARDS), severe trauma, sepsis, severe pancreatitis, and massive bleeding. These diseases involve multiple systems and organs throughout the body, and the risk of rapid deterioration of the condition is high, and the treatment requirements are extremely high.

[0003] Among several common diseases in critically ill surgical patients, venous thromboembolism (VTE) refers to the combined symptoms of deep vein thrombosis (DVT) and pulmonary embolism (PE), and its onset characteristics include potential concealment and multifactorial induction. The occurrence of venous thromboembolism is often associated with immobility, surgical operations, tumors, pregnancy, and certain genetic susceptibility factors, especially in the elderly and patients with chronic diseases. Its symptoms are often not obvious. DVT may manifest as swelling, pain, and redness of the limbs, while PE may cause sudden dyspnea, chest pain, and hemoptysis. It is often misdiagnosed as other diseases and delayed treatment. The harm of venous thromboembolism is mainly reflected in its potential lethality and serious complications. Pulmonary embolism can lead to a sharp decline in cardiopulmonary function and even endanger life, while untreated DVT may further evolve into PE. In addition, patients with venous thromboembolism may face chronic sequelae during the recovery process, such as pain and swelling in the lower limbs, which seriously affect the quality of life. Therefore, in the treatment of critically ill surgical patients, it is crucial to conduct risk assessment as early as possible, promptly identify and intervene in the catastrophic consequences brought about by the occurrence and development of VTE, and thus ensure the safety of patients' lives.

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] Surgery patients usually suffer from serious diseases that are life-threatening or affect the function of major organs. The characteristics of their condition are mainly reflected in the complex etiology, rapid progression of the disease, and multiple changes in the condition. Common surgical critical illnesses include deep vein thrombosis, pulmonary embolism, cardiac embolism, cerebral embolism, multiple organ dysfunction syndrome (MODS), acute respiratory distress syndrome (ARDS), severe trauma, sepsis, severe pancreatitis, and massive bleeding. These diseases involve multiple systems and organs throughout the body, and the risk of rapid deterioration is high, requiring extremely high treatment requirements.

[0027] First, critically ill surgical patients are often accompanied by multiple organ damage or failure. Multiple organ dysfunction is a common manifestation of critically ill surgical patients, especially when infection or trauma causes systemic inflammatory response, multiple organs such as the heart, lungs, kidneys and liver will successively develop dysfunction, and in severe cases, it may even lead to irreversible organ failure. Therefore, the treatment of critical surgical diseases should not only focus on the treatment of the main disease, but also require comprehensive monitoring and supportive treatment of each affected organ. Secondly, the course of critically ill surgical patients progresses rapidly, and the condition is complex and changeable. The vital signs of critically ill patients may fluctuate greatly in a short period of time, and the condition is susceptible to various factors (such as infection, trauma, etc.). The patient's immune function is often weakened, so it is easy to be infected and may quickly progress to sepsis, further exacerbating multiple organ dysfunction. In addition, the impact of trauma and surgery on the body may cause a large amount of fluid and electrolyte imbalance, bleeding tendency, and metabolic disorders, further exacerbating the difficulty of disease management. Finally, critically ill surgical patients require comprehensive treatment with multidisciplinary collaboration. The diagnosis and treatment of critical surgical diseases involves collaboration in many aspects such as surgery, intensive care, anesthesia, nutrition, and infection control. Customized treatment plans are needed for different conditions and complications. Taking severe pancreatitis as an example, in addition to surgical intervention, it also requires close cooperation among multiple disciplines such as internal medicine, intensive care, and nutritional support. In addition, the care of critically ill patients is also crucial, such as the correct use of ventilators and close monitoring of hemodynamics, which can help improve prognosis. In summary, the characteristics of the diseases of critically ill surgical patients are complex causes, variable conditions, and high treatment requirements, which require reliance on multidisciplinary comprehensive treatment.

[0028] Among the common diseases in critically ill surgical patients, venous thromboembolism (VTE) refers to the combined symptoms of deep vein thrombosis (DVT) and pulmonary embolism (PE), and its pathogenic characteristics include potential concealment and multifactorial induction. The occurrence of VTE is often associated with immobility, surgical operations, tumors, pregnancy and certain genetic susceptibility factors, especially in the elderly and patients with chronic diseases. Its symptoms are often not obvious. DVT may manifest as swelling, pain and redness of the limbs, while PE may cause sudden dyspnea, chest pain and hemoptysis, and is often misdiagnosed as other diseases, delaying treatment. The harm of VTE is mainly reflected in its potential lethality and serious complications. Pulmonary embolism can lead to a sharp decline in cardiopulmonary function and even endanger life, while untreated DVT may further evolve into PE. In addition, VTE patients may face chronic sequelae during the recovery process, such as pain and swelling in the lower limbs, which seriously affects the quality of life.

[0029] Therefore, it is crucial to propose a VTE risk assessment system, equipment, medium and product for critically ill surgical patients to identify and intervene in VTE as early as possible, which is crucial to protecting the life safety of critically ill surgical patients. Preventive measures such as anticoagulant therapy and appropriate activity recommendations are effective means to reduce the incidence of VTE and improve patient prognosis.

[0030] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0031] In an exemplary embodiment, Figure 1 As shown, a VTE risk assessment system for critically ill surgical patients is provided, including: a patient information collection module M1, a risk factor analysis module M2, a modified Caprini thrombosis risk score calculation module M3 and a VTE risk assessment module M4; the patient information collection module M1 is used to collect basic information and surgery-related information of critically ill surgical patients, such as age, gender, medical history, surgery type and other information; the risk factor analysis module M2 is used to analyze the basic information and surgery-related information of critically ill surgical patients and screen out risk factors that are strongly correlated with thrombosis; the modified Caprini thrombosis risk score calculation module M3 is used to calculate a modified Caprini thrombosis risk score according to the screened risk factors and the modified Caprini thrombosis risk assessment table; the VTE risk assessment module M4 is used to determine the risk level of VTE in critically ill surgical patients according to the modified Caprini thrombosis risk score.

[0032] In a specific embodiment, the modified Caprini thrombosis risk assessment table is shown in Table 1. The first row of Table 1 needs to fill in the basic medical information of surgical critically ill patients such as department, bed number, name, gender, age and hospitalization number. The subsequent risk factors include four levels A, B, C, and D. The risk factors of level A are further divided into universal risk factors A1 and risk factors A2 for female patients. When calculating the modified Caprini thrombosis risk score, the risk factor scores of the four levels A, B, C, and D are first counted respectively, and then the total score of each risk factor is calculated. For the risk factors related to surgery in Table 1, the "*" indicates that only one can be selected.

[0033] Table 1 Modified Caprini Thrombosis Risk Assessment Table

[0034]

[0035]

[0036] The modified Caprini Thrombosis Risk Assessment Table is a common clinical tool newly introduced to assess the risk of VTE in critically ill surgical patients based on the current new clinical diagnosis and treatment situation. It is used to assess the factors of patients' risk of venous thromboembolism (VTE). Its advantages are mainly reflected in three aspects: simplicity, effectiveness and personalized management. Since the original Caprini Thrombosis Risk Assessment Table was first proposed by American anesthesiologist Ralph Caprini in 2005, but now it has been nearly 20 years, the original Caprini Thrombosis Risk Assessment Table can no longer meet the needs of today's new clinical diagnosis and treatment situation. In view of this, this application introduces a new modified Caprini Thrombosis Risk Assessment Table. First, the modified Caprini Thrombosis Risk Assessment Table has the characteristics of simple operation. Medical staff can quickly complete the assessment and quantify the patient's risk factors through the scoring system, making the assessment process efficient and easy to understand. Secondly, the assessment table has a high predictive validity. Studies have shown that it can accurately identify high-risk patients, thereby providing a basis for timely preventive measures and reducing the incidence of VTE. In addition, the personalized management advantage of the modified Caprini Thrombosis Risk Assessment Table allows the medical team to develop corresponding prevention strategies based on the specific risk factors of each patient, such as the use of anticoagulants, promotion of activities, or mechanical prevention, to ensure the pertinence and effectiveness of intervention measures. In summary, the modified Caprini Thrombosis Risk Assessment Table not only improves the clinical ability to identify the risk of VTE, but also promotes patient-centered nursing management, improving the patient's life safety and treatment effect.

[0037] In another exemplary embodiment of the present application, the VTE risk assessment system for critically ill surgical patients also includes: a genetic risk gene screening module M5, which is used to perform VTE genetic risk gene screening according to the blood test results of critically ill surgical patients to determine whether there is a VTE genetic risk gene. Specifically in this embodiment, the first gene site that the genetic risk gene screening module M5 needs to screen is PROC (C>T), the reference allele is C, and the OR value is 7.34, the second gene site is PROC (de1AAG), the reference allele is DUP, and the OR value is 2.71, and the third gene site is THBD (G>T), the reference allele is G, and the OR value is 2.8. Critically ill surgical patients with VTE genetic risk genes who have been screened should use the modified Caprini thrombosis risk assessment table as soon as possible to perform a modified Caprini thrombosis risk score and perform VTE prevention and treatment.

[0038] The significance of genetic screening for VTE genetic risk is to achieve precise prevention and personalized management by identifying the genetic susceptibility of critically ill surgical patients. The occurrence of venous thromboembolism (VTE) is closely related to multiple genetic factors, such as genetic defects in antithrombin, protein C, protein S, etc. These genetic variations may significantly increase the risk of thrombosis in individuals. Through genetic screening, these susceptible individuals can be identified early in the high-risk population, and then corresponding prevention strategies can be formulated for them, such as targeted use of anticoagulant therapy or lifestyle adjustments. This not only helps to reduce the incidence of VTE, but also reduces the risk of complications and death associated with it. In addition, genetic screening can also provide family members with important health information, helping them understand their own risks and conduct corresponding monitoring and prevention. By integrating genetic information with clinical evaluation, medical providers can achieve more effective risk management and improve the overall quality of care for patients. Therefore, genetic screening for VTE genetic risk has important practical significance in improving the level of personalized medicine, optimizing prevention strategies, and reducing the burden of disease.

[0039] In another exemplary embodiment of the present application, the VTE risk assessment system for critically ill surgical patients also includes: a phased assessment module M6, which is used to calculate a modified Caprini thrombosis risk score according to the modified Caprini thrombosis risk assessment table at different stages of medical treatment for critically ill surgical patients; the different stages of medical treatment for critically ill surgical patients include admission, preoperative, postoperative, when the condition worsens and discharge.

[0040] After obtaining the modified Caprini thrombosis risk score in the above stages, the system can promptly feedback the VTE genetic risk gene screening results and the results obtained according to the modified Caprini thrombosis risk assessment table to medical staff for reference, and promptly inform the patients of their condition and treatment risks for critically ill surgical patients at risk of VTE, and take timely treatment measures for symptomatic treatment. In a specific embodiment of the present application, the VTE risk assessment system for critically ill surgical patients also includes: a VTE personalized prevention and treatment recommendation module M7, which is used to determine treatment measures based on the risk level of VTE in critically ill surgical patients, and inform critically ill surgical patients of their condition and treatment risks, and prompt them to take timely treatment measures for symptomatic treatment. Specifically in this embodiment, treatment measures are determined based on the risk level of VTE in critically ill surgical patients, which may specifically include:

[0041] When the risk level of VTE in critically ill surgical patients is low, it is recommended to mobilize as soon as possible, not to use anticoagulants, and to give lower limb massage and passive movement twice a day and pneumatic compression therapy once a day.

[0042] When the risk level of VTE in critically ill surgical patients is medium, 4000U of low molecular weight heparin sodium is injected subcutaneously once a day, and lower limb massage, passive movement and pneumatic compression therapy are given twice a day.

[0043] When the risk level of VTE in critically ill surgical patients is high, 4000U of low-molecular-weight heparin sodium is injected subcutaneously once a day, lower limb massage and passive movement are performed four times, and pneumatic compression therapy is given twice a day.

[0044] When the risk level of VTE in critically ill surgical patients is extremely high, 4000U of low-molecular-weight heparin sodium is injected subcutaneously once a day, lower limb massage and passive movement are performed four times, and pneumatic compression therapy is given three times a day.

[0045] In another exemplary embodiment of the present application, the VTE risk assessment system for critically ill surgical patients also includes: a post-discharge continuous tracking reminder module M8, which is used to remind discharged critically ill surgical patients who have been treated with thrombus prevention drugs of the necessity of receiving treatment within the recommended course of treatment, and informs them of the importance of reducing the risk of VTE through VTE prevention measures. Specifically in this embodiment, VTE prevention measures that can be taken by discharged critically ill surgical patients include: early mobilization, wearing elastic stockings, using intermittent air pressure devices, taking anticoagulants (such as aspirin, etc.) as prescribed by doctors, and / or receiving regular follow-up monitoring.

[0046] certainly, Figure 1 The architecture shown is only exemplary and can be omitted according to actual needs when implementing different functions. Figure 1 One or at least two components of the system shown.

[0047] The above-mentioned VTE risk assessment system for surgical critically ill patients provided by the present application can identify the risk of VTE in surgical critically ill patients as early as possible by adopting VTE genetic risk gene screening and dynamically applying the modified Caprini thrombosis risk assessment table. Early initiation of VTE physical therapy and drug prevention can effectively reduce the formation of limb DVT, and prevent and treat serious diseases such as pulmonary embolism, cardiac embolism, cerebral embolism, etc. after thrombus detachment, which endanger the patient's life, and will not increase the occurrence of serious events such as abnormal bleeding, intracranial hemorrhage, gastrointestinal bleeding and death. It is relatively safe and effective, and can timely initiate VTE physical therapy and drug prevention for surgical critically ill patients early, reduce the incidence of venous thrombosis and the severity of the disease in surgical critically ill patients, and track and inform patients of preventive measures to reduce the risk of VTE after they are discharged from the hospital. The present application scheme can provide a new theoretical basis for the treatment of surgical critically ill patients, promote the development of precision and personalized treatment, and thus comprehensively improve the treatment effect of surgical critically ill patients.
