Description

Technical Field

[0001] The present invention relates to the field of medical technology, and in particular to a method and system for evaluating postoperative complications of cardiothoracic surgery based on data analysis. Background Art

[0002] Cardiothoracic surgery is highly complex and risky. The occurrence of postoperative complications has a crucial impact on the patient's recovery. Accurately assessing the risk of postoperative complications and taking effective management and intervention measures in a timely manner are the key to improving patients' treatment outcomes and quality of life. However, there is currently a lack of systematic and accurate methods for evaluating postoperative complications in cardiothoracic surgery.

[0003] At present, the evaluation of postoperative complications mainly relies on the doctor's clinical experience and limited indicator observation. Doctors make a comprehensive analysis of the patient's surgical conditions, preoperative examination results, basic information, and postoperative recovery status, and use their own professional knowledge and experience to judge the possibility of complications in patients. Some medical institutions also use traditional statistical methods to conduct a simple analysis of historical clinical data to obtain some rules about the occurrence of complications.

[0004] Existing technologies rely on doctors’ experience for evaluation, which is highly subjective. Different doctors may have different judgments and lack unified standards and objective basis. Relying on only a limited number of indicators for judgment cannot fully consider the impact of various factors on the occurrence of complications. For example, only focusing on certain preoperative examination results or a single vital sign after surgery can easily overlook other important factors. Traditional methods lack systematic analysis and evaluation, and cannot comprehensively consider multiple factors such as the complexity of the operation, basic patient information, preoperative complications, and postoperative recovery status, making it difficult to accurately calculate the risk of complications. Due to the limitations of existing technologies, the assessment of complication risks is not accurate, which may lead to the neglect of high-risk patients or overtreatment of low-risk patients. Summary of the invention

The system comprehensively collects basic surgical data, preoperative examination data, patient basic information data and real-time postoperative recovery data, and comprehensively considers factors such as the complexity of the operation, preoperative complication index, patient basic information index and postoperative vital signs comprehensive index, so as to more comprehensively assess the risk of complications; comprehensively considers various conditions before and after the patient's operation, conducts systematic analysis and assessment of complication risks, improves accuracy, avoids neglect of high-risk patients and overtreatment of low-risk patients, and provides accurate reference for doctors to formulate personalized postoperative management and intervention strategies.

BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Figure 1 The present invention is a flowchart of a method for evaluating postoperative complications of cardiothoracic surgery based on data analysis. DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments 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] See also Figure 1 The present invention provides a method for evaluating postoperative complications of cardiothoracic surgery based on data analysis, comprising: Obtain basic surgical data, preoperative examination data, basic patient information data and real-time postoperative recovery data of patients after cardiothoracic surgery.

[0034] Specifically, basic surgical data are crucial for assessing the complexity of the operation; preoperative examination data help calculate the preoperative complication index, thereby assessing the patient's physical condition before surgery; and patient basic information data and real-time postoperative recovery data together provide a basis for calculating the patient's basic information index and postoperative vital signs comprehensive index.

[0035] Calculate the surgical complexity coefficient based on the basic surgical data and calculate the surgical complexity based on the surgical complexity coefficient ; Calculate the preoperative complication index based on preoperative examination data ; Calculate the patient basic information index based on the patient's basic information data , calculate the postoperative vital signs comprehensive index based on real-time postoperative recovery data .

[0036] Specifically, the system calculates the surgical complexity impact coefficient based on the basic surgical data, and determines the complexity of the surgery based on this coefficient. This process considers multiple factors such as operation duration, operation type, surgical site, and the number and type of medical devices used to evaluate the complexity of the surgery; the preoperative complication index is calculated based on preoperative examination data, which reflects the patient's physical condition and potential risks before surgery; the system calculates the patient's basic information index and postoperative vital signs comprehensive index based on the patient's basic information data and real-time postoperative recovery data through information processing methods and comprehensive evaluation methods. These two indices together reflect the patient's overall health status and postoperative recovery.

[0037] Depending on the complexity of the surgery , preoperative complication index , Patient Basic Information Index Postoperative vital signs index , calculate the complication risk score .

[0038] Specifically, the system calculates the complication risk score based on the complexity of the operation, the preoperative complication index, the patient's basic information index, and the comprehensive postoperative vital signs index.

[0039] Set the complication risk score threshold set , the complication risk score Complication risk score threshold set Make comparisons, determine the risk level of complications, develop appropriate postoperative management and intervention strategies, and generate an evaluation report.

[0040] Specifically, the system sets a set of complication risk score thresholds, compares the calculated complication risk score with these thresholds, and determines the risk level of the complication. Based on the complication risk level, the system formulates postoperative management and intervention strategies and generates an evaluation report. Based on the results of the above steps, the system automatically generates an evaluation report including the complication risk level, postoperative management and intervention strategies for reference by medical staff. This report will help medical staff better understand the patient's condition and formulate a more accurate treatment plan.

[0041] In the preferred embodiment of the cardiothoracic surgery postoperative complication evaluation method based on data analysis, the specific steps of calculating the surgical complexity influence coefficient are: The surgical complexity coefficient includes the technical difficulty coefficient and risk level factor .

[0042] Basic surgical data include surgical factor scores and surgical risk scores.

[0043] Surgical factor scores include surgery type scores , Surgery time score , Organ tissue type score and the degree of innovation in surgical techniques .

[0044] Calculate the technical difficulty coefficient based on the surgical factor score , the specific formula is as follows:

[0045] in, Score the type of surgery The impact factor is 0.1≤ ≤0.3, Scoring the surgical time The impact factor is 0.2≤ ≤0.4, Scoring organ tissue types The impact factor is 0.3≤ ≤0.5, Degree for Innovation in Surgical Technology The impact factor is 0.1< ≤0.3 and .

[0046] Surgical risk score including surgical urgency score , surgical site complexity score and surgical team experience rating .

[0047] Calculate the risk level coefficient based on the surgical risk score , the specific formula is as follows:

[0048] in, Scoring surgical urgency The weight coefficient is 0.2≤ ≤0.5, Representative surgical site complexity score The weight coefficient is 0.1< ≤0.3, Rate the surgical team experience The weight coefficient is in the range of 0.3≤ ≤0.6, and + + =1.

[0049] It should be noted that by obtaining a large number of cardiothoracic surgery cases, these surgical cases were classified according to the standards of cardiothoracic surgery. The classification categories can be simple operations, such as suture of small chest wounds, resection of superficial tumors, etc., medium-difficulty operations such as common heart valve repairs, correction of some congenital heart disease, etc., complex operations such as heart transplants, complex large blood vessel operations, etc. Assign a corresponding score to each category, such as 1 to 3 points for simple operations, 4 to 6 points for medium-difficulty operations, and 7 to 9 points for complex operations. Then, according to the specific type of surgery of the patient to be evaluated, the corresponding classification is performed to obtain the surgery type score. .

[0050] Collect the hospital's past time data for similar surgeries and determine the approximate time range for different types of surgeries. For example, divide the surgical time into short surgeries that are less than or equal to a specific time A, such as 2 hours, medium surgeries that are from time A to time B, such as 2 to 4 hours, and long surgeries that are greater than time B, such as greater than 4 hours. Assign a corresponding score to each time range, such as 1 to 3 points for short surgeries, 4 to 6 points for medium surgeries, and 7 to 9 points for long surgeries. When evaluating patients, determine the surgical time score based on the range of the patient's actual surgical time. .

[0051] The surgery is classified according to the importance and complexity of the organs and tissues involved. It can be divided into those involving a single simple organ and tissue, such as only superficial tissues such as skin and muscle or a single small organ, those involving moderately complex organs and tissues, such as a single medium-important organ or a few related tissues, and those involving multiple complex and important organs and tissues. Each category is assigned a corresponding score, such as 1 to 3 points for a single simple organ and tissue, 4 to 6 points for moderately complex organs and tissues, and 7 to 9 points for multiple complex and important organs and tissues. The organ and tissue type score is determined based on the organs and tissues involved in the surgery of the patient to be evaluated. .

[0052] If the surgery uses conventional, mature and widely used technology, it will be rated as low innovation and given 1 to 3 points; if it is a new technology that has been clinically verified to a certain extent, it will be rated as medium innovation and given 4 to 6 points; if it is a cutting-edge and highly innovative technology that has not yet been widely used, it will be rated as high innovation and given 7 to 9 points. The score of surgical technical innovation is determined based on the technical innovation of the surgery performed on the patient to be evaluated. .

[0053] Technical Difficulty Coefficient It aims to comprehensively consider the complexity of the operation at the technical level. It is determined by the scores of four surgical factors: the type of operation score, the operation time score, the organ and tissue type score, and the degree of innovation of surgical technology. The type of operation score means that different operation type scores correspond to different operational difficulties and technical requirements. For example, heart valve replacement is usually more technically difficult than simple chest wound suture; the length of the operation time score reflects the complexity of the operation. A longer operation time score may mean more operation steps, higher risks, and a greater burden on the patient's body; the difficulty of the operation will vary depending on the organ and tissue types involved. Operations involving important and complex organs and tissues are usually more challenging; the use of new surgical techniques or cutting-edge innovative technologies often have higher technical difficulties due to the lack of extensive practical experience and mature operating procedures.

[0054] Each surgical factor was assigned a specific impact factor, which reflected the relative importance of each surgical factor in the overall technical difficulty; Score the type of surgery The impact factor is 0.1≤ ≤0.3, which means that the contribution of the surgery type score to the technical difficulty coefficient is relatively small but not negligible. Scoring the surgical time The impact factor is 0.2≤ ≤0.4, indicating that the surgical time score has a certain importance for technical difficulty. Scoring organ tissue types The impact factor is 0.3≤ ≤0.5, indicating that the organ tissue type score accounts for a large proportion in the technical difficulty assessment. Degree for Innovation in Surgical Technology The impact factor is 0.1< ≤0.3, indicating that the degree of surgical technical innovation has a relatively small but significant impact on technical difficulty. , ensuring that the sum of the four influencing factors is 1, making the technical difficulty coefficient a reasonable value under the combined effect of various surgical factors.

[0055] The urgency score of the operation is that the patient's condition is stable and there is sufficient time for comprehensive preoperative examination and preparation. For example, in conventional heart valve replacement surgery, the patient is in good physical condition and the operation can be arranged within weeks or months. This type of operation has a relatively low risk and is scored 1 to 3 points. If the patient's preoperative examination results are good, the surgical plan is mature, and there is enough time for doctor-patient communication and psychological preparation, a score close to 3 points can be given; if the patient has some minor symptoms but does not affect the arrangement and conduct of the operation, a score of about 2 points can be given; if the patient's condition is more complicated, but it can still be prepared in a longer period of time, a score close to 1 point can be given; the score range for limited-time surgery is 4 to 6 points, and the patient's condition requires surgery within a certain period of time, but it is not as urgent as an emergency. For example, some tumor patients need surgery within a few weeks to prevent the condition from worsening. The time urgency of this type of operation is relatively high, and the risk is also increased compared to elective surgery, and a score of 4 to 6 points is given. If the patient's condition is relatively stable, but surgery is required in a relatively short period of time, such as within 1 to 2 months, a score of close to 4 points will be given; if the patient's condition has a certain risk of progression, but there is still a certain amount of time for preparation, a score of about 5 points can be given; if the patient's condition is more urgent, but there is still a certain buffer time for preoperative preparation, a score of close to 6 points will be given; Emergency surgery: score range: 7 to 9 points Specific criteria, the patient's condition is critical and surgery is required immediately to save life. For example, severe heart trauma, rupture of large blood vessels, etc. This type of surgery is extremely risky and time-sensitive, and a score of 7 to 9 points will be given. If the patient's vital signs are unstable, but there is still a certain chance of rescue, a score of close to 7 points can be given; if the patient's condition is very critical and surgery is required in the shortest possible time, a score of about 8 points will be given; if the patient's life is in extreme danger and surgery is the only way to save life, a score of close to 9 points will be given.

[0056] Score of complexity of surgical site The structure of the surgical site is relatively simple and easy to operate. The score range is 1 to 3 points. The specific standard is that the organs and tissues involved in the surgical site are relatively simple, the structure is clear, and the difficulty of the surgical operation is relatively low. For example, simple skin incision suture, superficial tumor resection and other operations. If the surgical site only involves skin and subcutaneous tissue, and the operation is simple, a score close to 1 point is given; if the surgical site involves some superficial small organs or tissues, but the operation is not difficult, a score of about 2 points can be given; if the surgical site is relatively simple, but requires certain delicate operations, a score close to 3 points is given. The structure of the surgical site is relatively complex, but there is a certain surgical experience for reference. The score range is 4 to 6 points. The specific standard is that the surgical site involves multiple organs or tissues, the structure is relatively complex, but the doctor has certain experience in past operations for reference. For example, some heart valve repair surgery, congenital heart disease correction surgery of moderate complexity, etc. If the organs or tissues involved in the operation are relatively complex, but the operation plan is relatively mature, a score close to 4 points will be given; if the structure of the operation site is relatively complex, but the doctor has certain experience and skills to deal with it, a score of about 5 points can be given; if the complexity of the operation site increases the risk of the operation, but there are still certain successful cases to learn from, a score close to 6 points will be given; the structure of the operation site is extremely complex and the operation is difficult. The score range is: 7 to 9 points. The specific standard is that the operation site involves multiple important and extremely complex organs or tissues, the operation is extremely difficult, and the doctor's skills and experience are extremely high. For example, complex heart transplantation surgery, large blood vessel replacement surgery, etc. If the structure of the operation site is extremely complex and the operation risk is extremely high, a score close to 7 points will be given; if the complexity of the operation site makes the operation process challenging and requires high skills and experience, a score of about 8 points will be given; if the structure of the operation site is extremely complex and the difficulty of the operation is almost at the limit, a score close to 9 points will be given.

[0057] The surgical team experience score range is 1 to 9 points. The specific criteria are to determine the score by counting the number of similar operations performed by the surgical team in the past, the success rate and other indicators.

[0058] In terms of the number of surgeries, if the surgical team performed similar surgeries less than 5 times in the past year, a score of 1 to 3 points was given. For example, if the surgical team only performed 1 to 2 similar surgeries in the past year, a score close to 1 point was given; if 3 to 4 similar surgeries were performed, a score of about 2 points was given; if 4 to 5 similar surgeries were performed, a score close to 3 points was given. If the surgical team performed similar surgeries between 5 and 10 times in the past year, a score of 4 to 6 points was given. If the surgical team performed 5 to 7 similar surgeries, a score close to 4 points was given; if 7 to 8 similar surgeries were performed, a score of about 5 points was given; if 8 to 10 similar surgeries were performed, a score close to 6 points was given; if the surgical team performed more than 10 similar surgeries in the past year, a score of 7 to 9 points was given. For example, if the surgical team performed 10 to 15 similar surgeries, a score close to 7 points was given; if 15 to 20 similar surgeries were performed, a score of about 8 points was given; if more than 20 similar surgeries were performed, a score close to 9 points was given. In terms of success rate, if the success rate of similar surgeries performed by the surgical team in the past was less than 70%, a score of 1 to 3 points will be given. For example, if the success rate is between 50% and 70%, a score close to 1 point will be given; if the success rate is between 60% and 70%, a score of 1 to 3 points will be given.

[0059] The risk level coefficient is used to assess the degree of risk of the operation. It is determined by three surgical risk scores: surgical urgency score, complexity of the surgical site, and surgical team experience score. Emergency surgery usually means that the patient's condition is critical and the surgical risk is high; elective surgery has sufficient time for preoperative preparation and the risk is relatively low. Operations with complex surgical sites are difficult to perform and the risks are correspondingly higher. Experienced surgical teams are better able to cope with various situations and reduce surgical risks; inexperienced teams may face more uncertainties.

[0060] Each surgical risk factor is assigned a specific weight coefficient that reflects the relative importance of each risk factor in the overall risk level. Scoring surgical urgency The weight coefficient is 0.2≤ ≤0.5, indicating that the surgical urgency score has a greater impact on the risk level assessment. Representative surgical site complexity score The weight coefficient is 0.1< ≤0.3, indicating that the surgical site complexity score has a certain impact on the risk level. Rate the surgical team experience The weight coefficient is in the range of 0.3≤ ≤0.6, which means that the surgical team experience score plays an important role in the risk level assessment. + + =1, which ensures that the sum of the three weight coefficients is 1, making the risk level coefficient a reasonable value under the combined effect of various risk factors.

[0061] The above formula can comprehensively and systematically consider all aspects of the surgical complexity influencing coefficient by clearly dividing surgical factors and risk scores. The comprehensive consideration of the surgical type score, time, organ tissue type score and degree of technological innovation can help accurately assess the technical difficulty of the surgery and provide a basis for doctors to make technical preparations in advance. The analysis of the surgical urgency score, site complexity and surgical team experience score can effectively assess the surgical risk level, so that the hospital can reasonably allocate resources to deal with different risk conditions. The influencing factors and weight coefficients of each factor have clear value ranges, which improves the scientificity and stability of the calculation. At the same time, ensuring that the sum of the coefficients of each part is 1 makes the evaluation results more objective and reasonable, providing strong support for the accurate assessment and effective management of postoperative complications of cardiothoracic surgery, thereby improving the success rate of surgery and the quality of patient recovery.

[0062] In the preferred embodiment of the method for evaluating postoperative complications of cardiothoracic surgery based on data analysis: calculating the complexity of the surgery The specific steps are: The surgical factor score also includes the number of operation steps. .

[0063] According to the technical difficulty coefficient , Risk level coefficient and number of steps Calculating surgical complexity , the specific formula is as follows:

[0064] in, Represents the number of operation steps The weight coefficient is 0.1< ≤0.3, Technical difficulty coefficient The weight coefficient is in the range of 0.3≤ ≤0.6, is the risk level coefficient The weight coefficient is 0.2≤ ≤0.5, and + + =1.

[0065] It should be noted that this formula is used to calculate the complexity of cardiothoracic surgery, taking into account three factors: the number of operation steps, the technical difficulty coefficient, and the risk level coefficient. These three factors reflect the complexity of the surgery from different angles, and the overall complexity of the surgery is determined by weighted summation. The number of operation steps directly reflects the complexity of the surgical process. The more operation steps there are, the more complex the surgery may be. Represents the number of operation steps The weight coefficient is 0.1< ≤0.3, indicating that the relative importance of the number of operation steps in the overall evaluation of surgical complexity is relatively low, but it still has a certain impact. The technical difficulty coefficient is calculated by comprehensively calculating factors such as the surgery type score, surgery time score, organ tissue type score, and the degree of surgical technology innovation, reflecting the complexity of the surgery at the technical level. Surgeries with high technical difficulty usually require a higher level of medical technology and professional skills; Technical difficulty coefficient The weight coefficient is in the range of 0.3≤ ≤0.6, indicating that technical difficulty plays a more important role in the assessment of surgical complexity. The risk level coefficient is calculated based on factors such as the surgical urgency score, the complexity of the surgical site, and the surgical team experience score, reflecting the degree of risk of the surgery. High-risk surgeries not only pose a greater threat to the patient's life safety, but also place higher demands on the medical team's response capabilities; is the risk level coefficient The weight coefficient is 0.2≤ ≤0.5, indicating that risk level also plays an important role in the assessment of surgical complexity.

[0066] Weight coefficient , , The range of values ​​is determined based on clinical experience and data analysis, and they reflect the relative importance of the number of operation steps, technical difficulty coefficient, and risk level coefficient in the evaluation of surgical complexity. + + =1, ensuring that the sum of the weights of the three factors is 1, making the complexity of the operation a reasonable value under the combined effect of various factors, which can more accurately reflect the actual complexity of the operation and provide an important basis for the subsequent evaluation and management of postoperative complications.

[0067] This formula comprehensively considers the number of operation steps, technical difficulty coefficient and risk level coefficient, comprehensively and accurately evaluates the complexity of the operation, and avoids the one-sidedness of single factor evaluation. The weight of the number of operation steps is low but still considered, which can capture the impact of the cumbersomeness of the surgical process on the overall complexity. The weight of the technical difficulty coefficient is moderate to high, highlighting the importance of the technical level of the operation and providing a reference for doctors to prepare corresponding technical resources. The appropriate weight of the risk level coefficient helps hospitals to reasonably arrange measures to deal with different risks. The sum of the weight coefficients is one, which ensures the objectivity and scientificity of the evaluation. The complexity of the operation calculated by this formula can provide a more accurate basis for the evaluation of postoperative complications, enabling medical staff to formulate more targeted management strategies in advance, improve the success rate of the operation, and reduce the risk of complications. It is also conducive to the rational allocation of medical resources and the improvement of the overall medical level of cardiothoracic surgery and the quality of rehabilitation of patients.

[0068] In the preferred embodiment of the method for evaluating postoperative complications of cardiothoracic surgery based on data analysis: calculating the preoperative complication index The specific steps are:

[0069] Preoperative examination data including preoperative albumin level , Preoperative blood glucose level , preoperative creatinine level And preoperative white blood cell count .

[0070] Obtain normal physical data, including normal albumin values , normal blood sugar level , normal creatinine value Normal white blood cell values .

[0071] Calculate the preoperative complication index based on preoperative examination data and normal physical data , the specific formula is as follows:

[0072] in, Preoperative albumin level The adjustment parameter is >0; Preoperative blood glucose level The adjustment parameter is >0; The preoperative creatinine level The adjustment parameter is >0; Preoperative white blood cell count The adjustment parameter is >0.

[0073] In the preferred embodiment of the method for evaluating postoperative complications of cardiothoracic surgery based on data analysis: calculating the patient basic information index The specific steps are: Patient basic information data including patient height , patient weight , Patient age and patient gender index .

[0074] According to the patient's height and patient weight , calculate body mass index , the specific formula is as follows: .

[0075] According to the patient's age , calculate the age risk index , the specific formula is as follows:

[0076] Among them, the age of patients The value range is .

[0077] According to body mass index , Age Risk Index and patient gender index , calculate the patient basic information index , the specific formula is as follows:

[0078] in, Body Mass Index The weight coefficient is 0.1< ≤0.3, Age risk index The weight coefficient is in the range of 0.3≤ ≤0.6, Patient gender index The weight coefficient is 0.2≤ ≤0.5, and + + =1.

[0079] It should be noted that this formula is used to calculate the basic information index of cardiothoracic surgery patients, taking into account the patient's body mass index, age risk index and patient gender index. By taking a weighted sum of these three factors, the potential impact of the patient's basic health status on postoperative complications is comprehensively assessed.

[0080] According to the patient's height and patient weight , calculate body mass index . Reflects the patient's degree of obesity, different The value may be related to the patient's nutritional status, metabolic level, and underlying health problems. Calculated according to different situations. For patients aged 50 years or less ; Patients aged between 50 and 70 years, Patients aged 70 years or older, The age risk index reflects the differences in the risk of postoperative complications faced by patients of different age groups. The risk usually increases gradually with age.

[0081] Patient gender index This reflects the potential impact of gender differences on postoperative complications. The specific values ​​are determined based on clinical experience and data analysis. Different genders may differ in their susceptibility to certain diseases and postoperative recovery. Based on clinical experience, fixed values ​​are set for males and females.

[0082] Body Mass Index The weight coefficient is 0.1< ≤0.3, indicating The relative importance in the patient basic information index is relatively low. Age risk index The weight coefficient is in the range of 0.3≤ ≤0.6, indicating that age risk plays a more important role in assessing the patient's basic information. Patient gender index The weight coefficient is 0.2≤ ≤0.5, indicating that gender factors also have a certain impact on the patient's basic information. + + =1, ensuring that the sum of the weights of the three factors is 1, making the patient basic information index It is a reasonable value under the comprehensive effect of various factors. This can more objectively reflect the patient's basic health status and provide an accurate basis for assessing the risk of postoperative complications.

[0083] This formula comprehensively considers the patient's height, weight, age, and gender, and other basic information to comprehensively assess the patient's physical condition and provide a richer basis for the assessment of postoperative complications of cardiothoracic surgery. By calculating the body mass index, it can reflect the patient's nutritional and metabolic status, which helps to pay attention to the risks that may be caused by obesity or weight loss in advance. The introduction of the age risk index fully considers the differences in complications faced by patients of different age groups, making the assessment more targeted, and the patient's gender index reflects the potential impact of gender differences on postoperative complications. Setting the sum of the weight coefficients equal to 1 ensures the reasonable proportion of each factor in the comprehensive assessment, and improves the scientificity and objectivity of the assessment. The patient's basic information index calculated using this formula can help doctors more accurately judge the risk level of postoperative complications in patients, thereby formulating more personalized treatment and care plans, and improving the success rate of surgery and the quality of patient recovery.

[0084] In the preferred embodiment of the cardiothoracic surgery postoperative complication assessment method based on data analysis, the real-time postoperative recovery data includes the real-time body temperature value. , average body temperature during the postoperative period , systolic blood pressure , diastolic blood pressure , Systolic blood pressure range , diastolic blood pressure range , heart rate standard deviation , heart rate average , Abnormal breathing frequency and total number of breaths .

[0085] In the preferred embodiment of the method for evaluating postoperative complications of cardiothoracic surgery based on data analysis: calculating the postoperative vital signs comprehensive index The specific steps are: According to the real-time body temperature and average body temperature Calculate the temperature fluctuation index , the formula is as follows:

[0086] in, Indicates The body temperature values ​​measured at each time point; The value of is 1, 2, ... , is the total number of measurements.

[0087] Setting a Systolic Blood Pressure Target and diastolic blood pressure target .

[0088] According to systolic blood pressure , diastolic blood pressure , Systolic blood pressure range , diastolic blood pressure range , systolic blood pressure target and diastolic blood pressure target , calculate blood pressure index , the formula is as follows:

[0089] According to the temperature fluctuation index , heart rate standard deviation , heart rate average , Abnormal breathing frequency Total number of breaths and blood pressure index , calculate the postoperative vital signs comprehensive index , the formula is as follows:

[0090] in, Temperature fluctuation index The adjustment parameter is >0; Heart rate variability index The adjustment parameter is >0; Abnormal respiratory rate index The adjustment parameter is >0; Blood pressure index The adjustment parameter is >0.

[0091] It should be noted that the average body temperature The average temperature of the patient is obtained by measuring the patient's body temperature regularly and recording multiple temperature values ​​within a period of time after surgery. The average temperature value within a period of time after surgery is then obtained by summing up the measured temperature values ​​and dividing them by the number of measurements. . Systolic blood pressure target and diastolic blood pressure target It is the normal systolic and diastolic blood pressure range for healthy people of different age groups. However, for patients after cardiothoracic surgery, the determination of the target value needs to comprehensively consider factors such as the patient's preoperative baseline blood pressure, age, physical condition, and surgery type score. The doctor refers to the patient's medical records to understand the patient's preoperative blood pressure, and combines clinical experience and relevant medical guidelines to determine a more reasonable systolic and diastolic blood pressure target value. Heart rate standard deviation and heart rate average After surgery, the patient's heart rate is continuously monitored through ECG monitoring equipment. The average heart rate is obtained by summing up all the heart rate values ​​recorded during this period and dividing it by the number of records. The calculation of the heart rate standard deviation requires first calculating the square of the difference between each heart rate value and the heart rate average, and then calculating the square root of the average of these square values. The adjustment parameters are determined by training the model with a large amount of clinical data , , as well as .

[0092] This formula is used to calculate the comprehensive index of vital signs after cardiothoracic surgery. By comprehensively considering the patient's postoperative temperature fluctuations, blood pressure, heart rate variability, abnormal respiratory rate and other vital signs data, it comprehensively evaluates the patient's postoperative physical condition and potential complication risks.

[0093] Temperature fluctuation index , in, Indicates The body temperature values ​​measured at each time point, It is the average body temperature during a period of time after surgery. is the total number of measurements. This formula quantifies the degree of temperature fluctuation by calculating the sum of the squares of the deviations between the temperature value at each time point and the average temperature and then dividing it by the number of measurements. Large fluctuations in temperature may indicate complications such as infection, inflammation, or an abnormal stress response in the body.

[0094] Blood pressure index , the calculation formula is .in, is systolic blood pressure, is the diastolic pressure, is the systolic blood pressure range, is the diastolic blood pressure range, is the systolic blood pressure target value, is the diastolic blood pressure target value. This formula reflects the degree of deviation of blood pressure from the ideal state by calculating the square sum of the deviations of systolic and diastolic blood pressure from the target values ​​within their respective ranges and multiplying it by a coefficient. Abnormal blood pressure may lead to abnormal blood supply to organs and increase the risk of complications such as cardiovascular events.

[0095] Postoperative vital signs index ,in, , , as well as Temperature Fluctuation Index , heart rate variability index , respiratory rate abnormality index and the adjustment parameters of the blood pressure index, and all are greater than 0. This formula combines the temperature fluctuation index, heart rate variability index, respiratory rate abnormality index and blood pressure index, and through logarithmic operations and addition followed by power operations, each index can be balanced and coordinated with each other in the comprehensive calculation, thereby more comprehensively reflecting the comprehensive status of the patient's vital signs after surgery.

[0096] The above formula comprehensively evaluates the physical condition of patients after cardiothoracic surgery by taking into account multiple vital signs indicators such as temperature fluctuations, blood pressure, heart rate variability and abnormal respiratory rate, avoiding the limitations of single indicator evaluation. The temperature fluctuation index can promptly reflect whether the patient has abnormal conditions such as infection or inflammation. The blood pressure index helps monitor the stability of the cardiovascular system. The standard deviation and average value of the heart rate can reflect the state of heart function. The number of abnormal respiratory rate reflects the condition of the respiratory system. The setting of adjustment parameters enables the weight of each indicator to be adjusted according to actual conditions in the comprehensive calculation, thereby improving the flexibility and accuracy of the evaluation. The calculated comprehensive index of postoperative vital signs provides doctors with a quantitative reference indicator, which is convenient for timely detection of potential complications, formulation of personalized treatment and nursing plans, and improvement of the success rate of surgery and the quality of patient recovery. It also provides a favorable tool for clinical research.

[0097] In the preferred embodiment of the method for evaluating complications after cardiothoracic surgery based on data analysis: calculating the complication risk score The specific steps are: Depending on the complexity of the surgery , preoperative complication index , Patient Basic Information Index Postoperative vital signs index , calculate the complication risk score , the specific formula is as follows:

[0098] in, represents the intercept term, which is a real number. Represents the complexity of the surgery The degree of influence of is a real number; Represents the complexity of the surgery The degree of influence of is a real number; Preoperative complication index The degree of influence of is a real number; Representative patient basic information index The degree of influence of is a real number; Postoperative vital signs comprehensive index The degree of influence of , which is a real number.

[0099] It should be noted that this formula is designed to calculate the risk score of postoperative complications in cardiothoracic surgery based on the complexity of the operation, the preoperative complication index, the patient's basic information index, and the comprehensive index of postoperative vital signs. By comprehensively considering multiple key factors, it provides a quantitative indicator for assessing the possibility of postoperative complications in patients.

[0100] Intercept is a real number representing the basic risk score when all other factors are zero. It can be estimated based on a large amount of clinical data, reflecting the average risk level of complications without considering factors such as surgical complexity, preoperative complications, basic patient information, and postoperative vital signs. and The product of will affect the risk score. A positive number indicates that the more complicated the surgery is, the higher the complication risk score is. If it is a negative number, it means that the complexity of the operation is negatively correlated with the risk of complications, but this situation rarely occurs in practice. The specific value of is determined by statistical methods such as regression analysis of a large amount of clinical data, reflecting the actual impact of surgical complexity on the risk of complications; This reflects the impact of the preoperative complication index on the complication risk score. If the patient has more complications or high-risk factors before surgery, The value will be higher. and The product of will increase the risk score, indicating that poor preoperative condition of patients increases the risk of postoperative complications. The value of is also determined based on clinical data; It reflects the impact of the patient's basic information, such as age, gender, body mass index and other factors on the risk of complications. If the patient's basic information is poor, such as advanced age, obesity, underlying diseases, etc. The value may be higher. and The product of will increase the risk score, indicating that poor basic information of patients will increase the possibility of postoperative complications; This reflects the impact of the comprehensive status of postoperative vital signs on the risk of complications. Higher value, and The product of will increase the risk score, which means that poor postoperative vital signs will increase the risk of complications. The exponential function in the formula The combined effects of each factor were transformed nonlinearly, and the calculated complication risk score was obtained by taking the inverse and adding 1. The value ranges from 0 to 1, which makes it easy to intuitively understand and compare the risk of complications in different patients. Ultimately, this formula provides doctors with a complication risk assessment tool that takes multiple factors into consideration, which helps to develop personalized postoperative management strategies and intervention measures.

[0101] This formula comprehensively considers multiple key factors such as the complexity of the operation, the preoperative complication index, the patient's basic information index, and the comprehensive index of postoperative vital signs, and comprehensively evaluates the risk of postoperative complications in cardiothoracic surgery, avoiding the one-sidedness of single-factor evaluation. By accurately quantifying the degree of influence of each factor, it can more accurately reflect the actual risk situation faced by patients. The nonlinear transformation in the formula allows the risk score to be taken within a reasonable range, which is easy to intuitively understand and compare. This provides a scientific basis for doctors to formulate personalized postoperative management strategies, helps to take targeted intervention measures in advance, and reduces the possibility of complications. At the same time, the formula determines parameters based on a large amount of clinical data, has high reliability and practicality, can improve the scientificity and accuracy of medical decision-making, improve the treatment effect of cardiothoracic surgery and the quality of patient rehabilitation, and also provides a powerful tool for clinical research and medical quality improvement.

[0102] In the preferred embodiment of the method for evaluating postoperative complications of cardiothoracic surgery based on data analysis, the specific steps for evaluating the risk level of complications and formulating corresponding management and intervention treatment plans are: Complication risk score threshold set Including the first threshold and secondary threshold ,in, < .

[0103] When the complication risk score ≤ When the risk of complications is judged as mild, a primary postoperative management and intervention strategy is formulated and a primary assessment report is generated.

[0104] when <Complication risk score ≤ When the risk of complications is moderate, the secondary postoperative management and intervention strategy is formulated and an intermediate assessment report is generated.

[0105] when <Complication risk score When the risk of severe complications is determined, a three-level postoperative management and intervention strategy is formulated and an advanced assessment report is generated.

[0106] It should be noted that the historical clinical medical records of cardiothoracic surgery are collected. These medical records should contain detailed surgical information, patient preoperative examination data, basic information, real-time postoperative recovery data, whether complications occurred and the severity of complications, etc. Cardiothoracic surgery cases in the past period can be screened from the hospital's electronic medical record system to ensure the diversity and representativeness of the cases, covering different types of surgery, patients of different ages and physical conditions, etc. For each historical clinical medical record, the following indicators are calculated using the calculation method of this scheme: Operation complexity: According to factors such as operation type, operation time, organ tissue type and degree of surgical technology innovation, the operation complexity influence coefficient is calculated according to the formula to obtain the operation complexity. Preoperative complication index: Calculated based on preoperative examination data, taking into account factors such as the patient's previous medical history. Patient basic information index: Calculated by the corresponding formula based on the patient's height, weight, age and gender. Postoperative vital sign comprehensive index: Calculated according to a specific formula using indicators such as body temperature, blood pressure, heart rate and respiration in real-time postoperative recovery data. Complication risk score: The complication risk score is calculated based on the complexity of the operation, the preoperative complication index, the patient's basic information index, and the postoperative vital signs comprehensive index. Formula to calculate the risk score of complications from past medical history .

[0107] Preliminary classification: Based on the severity of complications that actually occurred in the medical records, all medical records were initially divided into four categories: no complications, mild complications, moderate complications, and severe complications. Medical records without complications can be used as a reference, and the main focus is on medical records with complications. Medical records with complications are further analyzed. Complication risk scores at different complication severity levels are calculated The distribution of the complication risk scores of the medical records with mild complications was calculated by the mean, median and other statistics. Similarly, the corresponding statistics of the medical records with moderate and severe complications were calculated. The primary and secondary thresholds were determined based on the statistical analysis results and clinical experience. Generally speaking, It can be set near the complication risk score statistic of the medical record with mild complications, so that when the complication risk score ⩽ It is judged as a mild concurrent risk. It is set at the boundary between moderate complications and severe complications, that is, when <Complication Risk Score ⩽ When <Complication Risk Score The threshold set obtained in the above way can more accurately reflect the actual clinical situation and provide a scientific and reasonable basis for evaluating the risk level of complications after cardiothoracic surgery.

[0108] When the complication risk score ≤ When the patient's risk of complications is relatively low, the risk of complications is relatively low.

[0109] The primary postoperative management and intervention strategy mainly includes routine postoperative care and observation. For example, regularly measuring vital signs, changing wound dressings on time, and providing reasonable nutritional support to promote recovery. At the same time, patients are encouraged to move appropriately to prevent complications such as thrombosis.

[0110] Generate a primary assessment report, which includes the patient's basic information, a brief description of the surgery, specific values ​​of various indexes, the basis for judging a mild risk, the management and intervention strategies adopted, etc., to provide basic data for subsequent follow-up and treatment.

[0111] when <Complication risk score ≤ , it represents a moderate risk of complications. The patient has a certain degree of risk of complications.

[0112] Secondary postoperative management and intervention strategies will strengthen monitoring and care. Increase the frequency of vital sign checks, closely observe wound healing and changes in patient symptoms. Preventive drug treatment may be given, such as antibiotics to prevent infection and anticoagulants to prevent thrombosis. At the same time, psychological counseling is provided to patients to reduce their psychological stress.

[0113] The intermediate assessment report generated, in addition to containing the contents of the primary assessment report, will also provide a detailed analysis of the reasons why the patient is at moderate risk, as well as the specific treatment measures taken and the expected results.

[0114] when <Complication risk score When , it indicates a severe risk of complications. The patient is more likely to develop complications.

[0115] Level 3 postoperative management and intervention strategies are more proactive. Prepare emergency equipment and medicines in advance and develop emergency plans. Organize multidisciplinary consultations, including cardiothoracic surgeons, anesthesiologists, intensive care physicians, nutritionists, etc., to jointly develop personalized treatment plans. More frequent laboratory tests and imaging examinations may be required to detect and treat complications in a timely manner.

[0116] Generate an advanced assessment report with the most detailed content, including a comprehensive analysis of the condition, multidisciplinary consultation opinions, implementation of emergency treatment measures, patient prognosis assessment, etc., to provide comprehensive guidance for the patient's subsequent treatment.

[0117] By setting a clear set of complication risk score thresholds, patients can be accurately divided into different risk levels, allowing medical resources to be allocated more reasonably. For patients with mild risk, conventional nursing strategies are adopted to ensure the basic rehabilitation needs of patients while avoiding over-medicalization. Moderate-risk patients can receive enhanced monitoring and care, timely detect potential problems and carry out preventive treatment to reduce the possibility of complications. Severe-risk patients can receive the most comprehensive and timely treatment through multidisciplinary consultations and emergency plans, thereby improving the success rate of treatment. The generated assessment reports of different levels provide doctors with detailed condition analysis and treatment basis, and also facilitate patients and their families to understand the condition, enhance their confidence in treatment and cooperation. Overall, this program improves the scientificity and accuracy of the evaluation and management of postoperative complications of cardiothoracic surgery, and helps improve the treatment effect and rehabilitation quality of patients.
