TECHNICAL FIELD

[0001] The present application relates to the medical technology field, and in particular to a visual pain assessment report system and method. BACKGROUND

[0002] The International Association for the Study of Pain defines "pain" as "an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage". In view of the multifaceted damage of pain to patients, pain has been listed as the fifth vital sign internationally. In a clinical environment, pain is difficult to assess and manage, and pain assessment is an important part of pain control and an important reference factor in medical diagnosis.

[0003] At present, there is a lack of a complete pain assessment system in hospitals, and it is difficult to visually assess the pain of patients according to the time of pain, the frequency of pain and the real-time physiological data (such as heart rate, blood pressure, respiratory rate, etc.) of patients, which brings resistance to the diagnosis of patient pain.

[0004] In relieving the pain of patients, painkillers are usually needed. The pain assessment system in the prior art is difficult to adjust the dose of painkillers according to the pain of patients and different physical factors (age, weight, etc.) of different patients. When the dose is small, the pain relief effect is poor, and when the dose is high, the patient's body will be negatively affected to a certain extent.

[0005] Therefore, there is an urgent need for a visual pain assessment report system and method to solve the above problems. SUMMARY

[0047] In the formula calculation:

[0048] This part represents the impact term of patient heart rate HR on the calculation of comprehensive pain value Ps, the numerator part takes the absolute value after subtracting the heart rate health value HRnorm from the patient heart rate HR, representing the deviation of the patient heart rate HR from the health value, and the constant 2 of the numerator part is regarded as the division of 1 / 2 of the denominator part, This part is the denominator, representing the maximum deviation allowed for the patient heart rate HR, and the This part, the deviation of the patient heart rate HR from the health value, is standardized to the range of 0-1, when the patient heart rate HR approaches the reference value HRnorm of the heart rate health value, the impact value of the patient heart rate HR of this part tends to 0, representing that the patient heart rate HR will not affect the calculation of the comprehensive pain value Ps, and the farther the patient heart rate HR deviates from the reference value HRnorm of the heart rate health value, the greater the numerator, and the higher the calculated comprehensive pain value Ps;

[0049] The influence of patient systolic blood pressure SBP, patient diastolic blood pressure DBP and patient respiratory rate RR on the calculation of comprehensive pain value Ps is the same as that of patient heart rate HR, and the sum of the impact terms of the four indexes is multiplied by one fourth to obtain the comprehensive impact term based on physiological indexes, and the sum of the comprehensive impact term and 1 is multiplied by the basic pain value Pd to obtain the comprehensive pain value Ps adjusted based on physiological indexes.

As the patient weight We increases, the calculated planned drug dose Dp also increases;

[0061] This part represents the impact of patient age Age on the calculated planned drug dose Dp, specifically:

[0062] When the patient age Age is greater than or equal to 30, the dose is reduced by 0.5% for every additional year, and when the patient age Age is less than 30, the minimum value of the patient age Age is taken as 30, at which time The value of this part is 1, representing young patients under the age of 30, and age has no impact on the calculation of the planned drug dose Dp;

[0097] And, the application calculates the planned administration amount Dp by comprehensively considering the basic administration amount Db, the patient weight We, the patient age Age and the comprehensive pain value Ps through the planned administration amount algorithm unit, which can better meet the specific needs of each patient, which helps to ensure that the patient receives the right amount of drug treatment, avoids the situation of insufficient or excessive amount, thereby improving the treatment effect and reducing the risk of adverse reactions, and since the pain condition and physiological indicators (heart rate, blood pressure, etc.) of the patient can be updated and obtained in real time in the pain assessment report system, the planned administration amount Dp can be dynamically adjusted according to the actual situation, and this dynamic adjustment mode can ensure the continuous effectiveness of the treatment.

[0098] Please refer to Figs. 1-2 The basic pain value algorithm unit is as follows:

[0099] ;

[0100] Wherein:

[0101] Pd represents the basic pain value;

[0102] Pi represents the pain intensity, which is the intensity of the i th pain of the patient in a day, measured by the doctor through the numerical rating scale, and Pi∈[0, 10];

[0103] Pct represents the pain time, which is the time of the i th pain of the patient in a day, in minutes;

[0104] N represents the number of pains, which is the number of pain attacks of the patient in a day;

[0105] Sp represents the sensitivity coefficient, which is the sensitivity coefficient of the i th pain of the patient in a day, used to adjust the severity of pain according to the pain site of the patient, Sp∈[0.6, 1.2], and specifically:

[0106] When the pain site is the limbs, it belongs to the category of surgical pain, which can be relieved by massage, rest or physical therapy, and the sensitivity coefficient is set to 0.6;

[0107] When the pain site is the back and neck, although it does not endanger life, but seriously affects the quality of life, the sensitivity coefficient is set to the moderate value 0.8;

[0108] When the pain site is the pelvic region pain, it is related to the reproductive system, urinary system or bone problems, and the sensitivity coefficient is set to the moderate value 0.9;

[0109] When the pain site is the lung, chest, abdomen, it belongs to the category of internal medicine pain, the sensitivity coefficient is set to 1, and the pain site is examined by ultrasound (B-ultrasound, color Doppler ultrasound, etc.) to evaluate the severity of the pain site and timely treatment (because the above-mentioned internal medicine pain category needs attention, the cause should be found in time to avoid the deterioration of the disease);

[0110] When the pain site is the heart and head, the risk is the greatest, and the sensitivity coefficient is set to the highest value 1.2. When the heart is painful, the heart is examined by ultrasound (B-ultrasound, color Doppler ultrasound, etc.) to evaluate the shape, movement and blood flow of the heart, and to find problems and treat them in time. When the head is painful, CT examination is performed (because the heart and head are the most important parts of the human body, and the cause needs to be found immediately and treated when the heart and head are painful);

[0111] In the formula calculation:

[0112] This part reflects the degree of aggravation of the influence of the high pain intensity Pi on the basic pain value Pd when the high pain intensity Pi is high, so as to increase the basic pain value Pd calculated by the patient when the pain is severe;

[0113] This part logarithmically processes the pain time Pct, and as the pain time Pct increases, the basic pain value Pd will increase, but the speed will slow down, so as to ensure that the pain time Pct has a positive effect on the calculation result basic pain value Pd while reducing the excessive effect of long-term pain on the calculation of the basic pain value Pd;

[0114] The intensity of the i-th pain is taken to the power of 1.2, and then multiplied by This part of the pain time Pct influence term is multiplied by the sensitivity coefficient Sp, and the i-th pain value is obtained, then the multiple pain values in a day are added and divided by the number of pain N, that is, the average basic pain value Pd in a day can be obtained.

[0115] In this embodiment:

[0116] The basic pain value Pd is calculated by the basic pain value algorithm unit by comprehensively considering the pain intensity Pi, the pain time Pct, the pain frequency and the sensitivity coefficient Sp, which provides a more comprehensive and detailed visual pain assessment. Compared with the single dependence on the subjective description of the patient or the simple score of the doctor, this pain assessment method can more accurately reflect the actual pain condition of the patient. The basic pain value Pd as a visual quantitative index helps to standardize the process of pain assessment. Different doctors or patients may have subjective differences when describing pain, and the calculation of the basic pain value Pd provides an objective measurement method, so that the pain conditions of different patients or different time points can be effectively compared and analyzed. The visual pain assessment report system can display the basic pain value Pd value and its change trend of the same patient through a graphical interface to dynamically monitor the change of the patient's pain condition, which helps the communication between the doctor and the patient, so that the patient can more intuitively understand his own pain condition, and the doctor can also use these data to explain the treatment plan and the expected effect to the patient, which is of great significance for timely adjusting the treatment plan, evaluating the treatment effect and predicting the pain development trend.

[0117] Please refer to Figs. 1-2 The comprehensive pain value algorithm unit is as follows:

[0118] ;

[0119] Wherein:

[0120] Ps represents the comprehensive pain value;

[0121] Pd represents the basic pain value;

[0122] HR represents the heart rate of the patient, which is measured by an electrocardiogram monitor, and the health value is 60-100;

[0123] SBP represents the systolic pressure of the patient, which is measured by an electrocardiogram monitor, and the health value is 90-139;

[0124] DBP represents the diastolic pressure of the patient, which is measured by an electrocardiogram monitor, and the health value is 60-89;

[0125] RR represents the respiratory rate of the patient, which is measured by an electrocardiogram monitor, and the health value is 12-22;

[0126] HRnorm represents the reference value of the heart rate health value, which is obtained by dividing the sum of the maximum value of the heart rate health value and the minimum value of the heart rate health value by 2, i.e. (100+60) / 2=80;

[0127] SBPnorm represents the baseline value of the systolic blood pressure health value, which is obtained by adding the maximum value of the systolic blood pressure health value to the minimum value of the systolic blood pressure health value and then dividing the sum by 2, i.e., (139+90) / 2=114.5;

[0128] DBPnorm represents the baseline value of the diastolic blood pressure health value, which is obtained by adding the maximum value of the diastolic blood pressure health value to the minimum value of the diastolic blood pressure health value and then dividing the sum by 2, i.e., (89+60) / 2=74.5;

[0129] RRnorm represents the baseline value of the respiratory rate health value, which is obtained by adding the maximum value of the respiratory rate health value to the minimum value of the respiratory rate health value and then dividing the sum by 2, i.e., (22+12) / 2=17;

[0130] α represents a correction factor, and the base value is 1, which is self-adjusted in the pain assessment reporting system;

[0131] In the formula calculation:

[0132] This part represents the influence term of the patient's heart rate HR on the calculation of the comprehensive pain value Ps, and the numerator part is obtained by taking the absolute value of the patient's heart rate HR minus the baseline value of the heart rate health value HRnorm, representing the deviation of the patient's heart rate HR from the health value. The constant 2 in the numerator part is regarded as the denominator part divided by 1 / 2, This part as the denominator is half of the heart rate health range, i.e., the maximum degree of deviation allowed for the heart rate HR, representing the maximum deviation allowed for the patient's heart rate HR. The This part, the deviation of the patient's heart rate HR from the health value is standardized to the range of 0-1. When the patient's heart rate HR approaches the baseline value of the heart rate health value HRnorm, the influence value of the patient's heart rate HR in this part tends to 0, representing that the patient's heart rate HR will not affect the calculation of the comprehensive pain value Ps. With the deviation of the patient's heart rate HR from the baseline value of the heart rate health value HRnorm being farther, the numerator is larger, and the calculated comprehensive pain value Ps is higher;

[0133] The influence of the patient's systolic blood pressure SBP, diastolic blood pressure DBP and respiratory rate RR on the calculation of the comprehensive pain value Ps is the same as that of the patient's heart rate HR. After adding the influence terms of the four indexes and multiplying by one fourth, the comprehensive influence term based on the physiological indexes is obtained. After adding 1 to this part of the comprehensive influence term, the basic pain value Pd is multiplied to obtain the comprehensive pain value Ps adjusted based on the physiological indexes.

[0134] In this embodiment:

[0135] The traditional pain assessment mainly relies on the subjective description of the patient, which may be affected by various factors such as personal perception, expression ability, etc., and the comprehensive pain value algorithm unit comprehensively considers the patient's heart rate HR, patient's systolic blood pressure SBP, patient's diastolic blood pressure DBP and patient's respiratory rate RR and combines the basic pain value Pd to calculate the comprehensive pain value Ps, so that medical personnel can obtain a quantitative and visual pain assessment index, which helps medical personnel to more accurately understand the patient's pain condition, by analyzing the comprehensive pain value Ps of the patient at different time points in the evaluation database, visual report, doctors can more easily explain the pain condition and treatment plan to the patient, patients can also intuitively understand their own pain condition and treatment effect through the visual pain assessment report system, which helps to enhance the patient's confidence in the treatment plan, and helps to promote communication between doctors and patients and enhance the patient's trust in doctors.

[0136] And since the calculation of the comprehensive pain value Ps involves real-time physiological data of the patient (such as heart rate, blood pressure, respiratory rate, etc.), the pain assessment report system can monitor the patient's pain condition in real time, and when the patient's pain condition changes dramatically, the system can quickly respond to provide an early warning to medical personnel, so that the treatment plan can be adjusted in a timely manner, for example, for patients with more severe pain, the dose of analgesic drugs can be increased or more effective drugs can be replaced, providing scientific and reliable data support for medical personnel in treating the patient's pain.

[0137] Please refer to Figs. 1-2 The planned drug administration amount algorithm unit is as follows:

[0138] ;

[0139] Wherein:

[0140] Dp represents the planned drug administration amount, which is the planned analgesic dose applied to the patient;

[0141] Db represents the basic drug administration amount, which is the basic dose of analgesic drugs taken by the patient;

[0142] We represents the patient's weight, which is obtained from the hospital information system;

[0143] Age represents the patient's age, which is obtained from the hospital information system;

[0144] Sa represents the gender adjustment factor, according to the difference in pain sensitivity and tolerance between men and women, women are 1.1 and men are 0.9;

[0145] Ps represents the comprehensive pain value, which is calculated by the comprehensive pain value algorithm unit;

[0146] In the formula calculation:

[0147] This part represents the impact of patient weight We on the calculated planned drug dose Dp. The drug distribution volume is related to body weight. The larger the body weight, the higher the dose required to achieve the same blood drug concentration. The linear impact of patient weight We on the calculated planned drug dose Dp is reflected by dividing the patient weight We by the standard weight 70. As the patient weight We increases, the calculated planned drug dose Dp increases;

[0148] This part represents the impact of patient age Age on the calculated planned drug dose Dp. The older the patient, the lower the metabolic capacity of the elderly, the lower the drug clearance rate, the easy accumulation of poisoning, and the appropriate reduction of analgesic dose. Specifically, when the patient age Age is greater than or equal to 30, the dose is reduced by 0.5% for every 1 year increase in age, and when the patient age Age is less than 30, the minimum value of the patient age Age is taken as 30, that is, The value of this part is 1, representing young patients under the age of 30, and age has no impact on the calculation of the planned drug dose Dp.

[0149] This part represents the impact of patient pain on the planned drug dose Dp. Since the range of the hyperbolic tangent function tanh is (-1, 1), after adding 1, the value of this part is in the range of (0, 2). The value of this part is in the range of (0, 2), and the constant 5 is the pain good threshold of the comprehensive pain value Ps. Specifically:

[0150] When the comprehensive pain value Ps is greater than 5, as the comprehensive pain value Ps increases, the value of the tangent function tanh in this part tends to 1, representing that as the patient's comprehensive pain value Ps increases, the required drug dose is twice the basic drug dose Db.

[0151] When the comprehensive pain value Ps is less than 5, as the comprehensive pain value Ps decreases, the value of the tangent function tanh in this part tends to -1, The calculated value tends to 0, representing that as the patient's comprehensive pain value Ps continues to decrease below the pain good threshold, the patient's recovery is good, and the analgesic drug dose is close to 0, avoiding the negative effects of excessive drug use on the patient's body.

[0152] In this embodiment:

[0153] The physiological condition, pain perception and drug response of each patient are unique, the planned drug delivery amount algorithm unit comprehensively considers the base drug delivery amount Db, patient weight We, patient age Age and comprehensive pain value Ps multiple influencing factors, can calculate more accurate planned drug delivery amount Dp, can better meet the specific needs of each patient, which helps to ensure that patients receive the right amount of drug treatment, avoid the situation of insufficient or excessive drug amount, thereby improving the treatment effect and reducing the risk of adverse reactions, since the pain condition and physiological indicators (heart rate, blood pressure, etc.) of the patient will change with the treatment process, therefore, it is necessary to adjust the drug dosage in time, and through the planned drug delivery amount algorithm unit, these data can be monitored in real time, and the planned drug delivery amount Dp is dynamically adjusted according to the actual situation, so as to ensure the continuous effectiveness of the treatment, the traditional drug dosage adjustment often depends on the experience and judgment of doctors, and through the visual pain assessment report system, the calculation process and result of the planned drug delivery amount Dp can be displayed, which can enhance the communication between doctors and patients, and make patients more clearly understand their treatment plan and drug basis.

[0154] In summary, the application provides a more scientific and efficient automatic calculation method, doctors can quickly develop a reasonable treatment plan according to the pain condition and physiological indicators (heart rate, blood pressure, etc.) of the patient, which improves the medical efficiency and reduces the workload of doctors.
