Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to the accompanying drawings, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The term "and/or" in the embodiments of the present invention describes an association relationship of associated objects, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.
The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present application, "a plurality" means two or more unless otherwise specified.
In the description of the present application, it is to be noted that, unless otherwise explicitly stated or limited, the term "connected" is to be understood broadly, and may for example be directly connected, indirectly connected through an intermediate medium, or be a communication between two devices. The specific meaning of the above terms in the present application can be understood in a specific case by those of ordinary skill in the art.
In the medical field, the severity of a disease of a patient can be known according to the medical score of the patient, and the method is very important for diagnosis and treatment of the disease. In the related art, the relationship between the physical examination information of the sample at a certain time and the medical score at the next time is obtained based on the public database, and by learning the relationship, the medical score at the next time of the patient can be predicted and obtained according to the physical examination information of the patient at a past certain time.
However, the constitution of patients in different regions is obviously different, and when all sample data in the public data are learned, the above scheme cannot effectively learn the relationship between the physical examination information of samples in the regions with fewer samples in a period of time and the medical score at the next moment, so that the medical score of the patients in the regions with fewer samples cannot be accurately determined.
The embodiment of the invention provides a method, a device, electronic equipment and a storage medium for determining a medical score, wherein a second training LSTM model is obtained by training based on a second sample in a public database, namely, the second training LSTM model with stronger learning characteristic capacity is trained by enough samples, and then the second training LSTM model is subjected to transfer training according to the first sample, so that the obtained first training LSTM model has stronger characteristic learning capacity and can accurately predict the medical score of a patient in a target area, and therefore, a target characteristic sequence corresponding to a target to be scored in the target area within a past period of time is input into the first training LSTM model, and the predicted medical score of the target to be scored at a target moment can be accurately obtained.
The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 1 is a schematic flow chart of a first medical score determining method provided in an embodiment of the present application, and as shown in fig. 1, the method may include:
step 101: and determining a target characteristic sequence according to a target characteristic value corresponding to a preset characteristic of the target to be evaluated in a first preset time before the current time.
In this embodiment, the future medical grade of the target to be evaluated needs to be predicted according to the related historical data of the target to be evaluated, and based on this, the historical data of the target to be evaluated needs to be obtained first and processed correspondingly.
The target characteristic value corresponding to the preset characteristic of the target to be evaluated in the first preset time before the current time is the parameter corresponding to the different body indexes of the target to be evaluated in the time, and the determined target characteristic sequence reflects the change of the parameter corresponding to the different body indexes of the target to be evaluated in the time along with the time. In this embodiment, the physical index may be various physical indexes, such as body weight, urine volume, PF ratio, mechanical ventilation, antibiotics, age, lymphocyte count, blood glucose level, prothrombin time, and the like.
In this embodiment, a first preset duration may be set according to an actual application scenario, where the longer the first preset duration is, the more accurate the prediction result is, but the calculation amount may also increase. Take the first preset time period as 5 hours as an example:
the first preset time period is 5 hours, and the current time is 12 pm, so that the first preset time period before the current time is 7 pm-12 pm earlier.
The above parameters are merely exemplary, and the present embodiment does not specifically limit the above parameters.
Step 102: and inputting the target characteristic sequence into a first training LSTM model to obtain the predicted medical score of the target to be scored at the target moment.
The target time is a time which is a second preset time after the current time, and the first training LSTM model is a trained LSTM model corresponding to a target area where the target to be evaluated is located.
In this embodiment, a future medical score of the target to be scored needs to be predicted according to the relevant historical data of the target to be scored, the first training LSTM model corresponding to the target area where the target to be scored is located learns the relation between the relevant historical data of the first sample in the database corresponding to the target area and the future medical score, and the medical score at the time of a second preset duration after the current time can be obtained by inputting the target feature sequence of the target to be scored in the historical time into the first training LSTM model.
In this embodiment, the second preset duration may be set according to an actual application scenario, which is not limited in this embodiment.
The first trained LSTM model may be obtained by:
and performing migration training on a second training LSTM model according to the first sample in the database corresponding to the target area to obtain the first training LSTM model, wherein the second training LSTM model is obtained by training the initial LSTM model based on the second sample in the public database.
If the initial LSTM model is trained directly according to the first sample in the database corresponding to the target region, the relevant features of the first sample in the target region can be learned, but generally, the number of samples in the database corresponding to one region is small, so the number of the first samples may not be enough to train the LSTM model, or the trained LSTM model has poor feature learning ability; if the initial LSTM model is trained directly from the second sample in the public database, the relevant features of the first sample in the target region may not be well learned.
In this embodiment, a second training LSTM model is obtained by training based on a second sample in a public database, that is, a second training LSTM model with strong learning characteristic capability is trained through enough samples, and then the LSTM model is subjected to migration training according to the first sample, so that the obtained first training LSTM model has strong characteristic learning capability and can accurately predict the medical score of a patient in the target region, and therefore, a target characteristic sequence corresponding to a target to be evaluated in a past period of time is input into the first training LSTM model, and the predicted medical score of the target to be evaluated can be accurately obtained.
In this embodiment, the database corresponding to the target area and the public database are not limited, and the public database may include a database corresponding to the target area, that is, the public database includes all the first samples; the public database may also partially include a database corresponding to the target region, that is, the public database includes a part of the first sample; the common database may also not comprise the database corresponding to the target area at all, i.e. the common database does not contain any first samples.
The public database may be any public clinical database containing a number of samples greater than a predetermined number threshold, such as a Medical Information Market for Intensive Care (MIMIC) database.
The present embodiment does not limit the type of the medical score, for example, the medical score is a Sequential Organ Failure Assessment (SOFA) score.
In some specific embodiments, the medical score is a SOFA score, and after a predicted SOFA score of the target to be scored at the target time is obtained, information carrying the predicted SOFA score is sent in a preset notification manner, so that after the information is received by a target person, symptom analysis is performed on the target to be scored based on the predicted SOFA score, treatment measures are taken in advance, and the like.
According to the scheme, the second training LSTM model is obtained through training based on the second sample in the public database, namely the second training LSTM model with strong learning characteristic capacity is trained through enough samples, and then the LSTM model is subjected to transfer training according to the first sample, so that the obtained first training LSTM model has strong characteristic learning capacity and can accurately predict the medical score of the patient in the target area, therefore, the target characteristic sequence corresponding to the target to be evaluated in the target area within a past period of time is input into the first training LSTM model, and the predicted medical score of the target to be evaluated can be accurately obtained.
Based on that the LSTM model learns not only the correspondence between the feature values and the medical scores but also the correspondence between the order of the feature values and the medical scores, i.e. the same feature values, but different orders may correspond to different medical scores, in the medical score determining method of some embodiments, the first preset duration may be divided into a plurality of time intervals to determine the predicted medical scores more accurately, as shown in fig. 2, and the method may include:
step 201: and selecting a target dynamic characteristic value representing the dynamic characteristic of the corresponding time period from all the dynamic characteristic values corresponding to the dynamic characteristic of the target to be scored in each time period in the plurality of time periods.
In this embodiment, the feature values of some features for different preset features are not changed over time or in a short time (a first preset time period), for example: body weight, urine volume, PF ratio, mechanical ventilation, antibiotics, age, etc.;
and the characteristic values of some characteristics can be changed in real time, such as lymphocyte count, blood sugar content, prothrombin time and the like.
Based on this, the preset features are classified into two types: static features that do not change over time or for short periods of time, and dynamic features that can change in real time.
In this embodiment, the feature values of the target to be scored corresponding to the static features in the multiple time periods are not changed, and the feature values corresponding to the static features in each time period do not need to be determined; the feature values of the target to be evaluated corresponding to the dynamic features in the plurality of time periods may change, and the feature values corresponding to the dynamic features in each time period need to be determined.
In this embodiment, if there are many types of dynamic features and feature values are collected more frequently, the dynamic features in each time period correspond to a large number of dynamic feature values, and the dynamic feature values are directly used as target dynamic feature values representing the dynamic features in the corresponding time period, so that the calculation amount of the first training LSTM model is large due to the large number of target dynamic feature values, the efficiency of determining the predicted medical score is low, and the timeliness requirement of the medical field for determining the predicted medical score is high.
Based on this, in some embodiments, the selecting of the target dynamic feature value representing the dynamic feature of the corresponding time period from all the dynamic feature values corresponding to the dynamic feature of the target to be scored in each time period of the multiple time periods may be implemented by, but is not limited to:
selecting at least one dynamic characteristic value as a dynamic characteristic value representing the corresponding type characteristic of the corresponding time period from the minimum dynamic characteristic value, the maximum dynamic characteristic value, the median dynamic characteristic value and the average dynamic characteristic value corresponding to each type of characteristic of the multiple types of characteristics of the target to be evaluated in each time period;
and taking the dynamic characteristic values of all types of characteristics representing each time interval as target dynamic characteristic values representing the dynamic characteristics of the corresponding time interval.
The first preset time is 5 hours, the current time is 12 pm, and the first preset time before the current time is 7 am-12 pm, as an example, the following description is made:
each hour is divided into 5 periods, namely 7 am-12 am: 7 am-8 am, noted as epoch 1, 8 am-9 am, noted as epoch 2, 9 am-10 am, noted as epoch 3, 10 am-11 am, noted as epoch 4, 11 am-12 am, noted as epoch 5.
