Based on the hardware structure, various embodiments of the method of the invention are provided.
Referring to fig. 2, in an embodiment of the method for detecting illegal opening inspection item behaviors of the present invention, the method for detecting illegal opening inspection item behaviors includes the steps of:
step S10, acquiring diagnosis and treatment data uploaded by a medical institution, and performing prediction and identification by taking the diagnosis and treatment data as the input of a preset data identification model to obtain a diagnosis and treatment data label;
the embodiment is applied to a third-party organization for detecting the diagnosis and treatment data, and the third-party organization can be, for example, a social medical insurance authority.
The medical institution may upload the medical data to the detection device using a terminal, for example, when the patient is settled at the medical institution after the visit or examination is completed, the settlement terminal of the medical institution uploads the medical data of the patient qualified for participation in the insurance to a server of a third-party institution. The medical data is visit data generated when a patient qualified for insurance visits and/or hospitalization in a medical institution, and may include disease diagnosis data of the patient, spending details during treatment, a list of examination items and/or medicines to be prescribed, and a prescription made by a doctor of the medical institution.
After the diagnosis and treatment data are obtained, the detection device can identify and match the diagnosis and treatment data to the corresponding standardized fields through the preset data identification model in the memory to obtain diagnosis and treatment data labels, each diagnosis and treatment data label can be a real numerical value, a vector or a category label and the like, and the content corresponding to the diagnosis and treatment data can be identified through the diagnosis and treatment data labels. The preset data recognition model is constructed based on machine learning, and relates to technologies such as a neural network, natural language processing and an attention mechanism.
Step S20, obtaining the number of times of examination of each user in the preset time from the diagnosis and treatment data label;
the diagnosis and treatment data labels obtained through prediction and identification of the diagnosis and treatment data and the preset data identification model can be multiple, and each diagnosis and treatment data label can represent a part of or all diagnosis and treatment data contents of a medical institution in one dimension. All the diagnosis and treatment data labels in the dimension of the examination items prescribed by the medical institution can be selected from the diagnosis and treatment data labels, and the examination times of each user in the medical institution in the preset time can be obtained according to the diagnosis and treatment data labels. Wherein the predetermined time may be one week, one month, one quarter, or one year. Of course, the preset time can also be set according to the detection time of the third-party institution.
Step S30, judging whether the checking times of any user in the preset time exceeds the threshold value;
since the medical institution often realizes arbitrage by opening more examination items for users, the higher the number of examination of one user is, the higher the possibility that the medical institution has illegal action of opening examination items is. Therefore, a threshold number of times can be set, and the threshold number of times is compared with the number of times of examination for each user in a medical institution, so as to confirm whether or not the medical institution performs a profit-setting operation by giving an illegal provision of an examination item.
The number threshold may be set according to actual needs, for example, determined according to the number of provinces and/or frequent population of a city where the medical institution is located, determined according to the institution level of the medical institution, or determined according to the popularity or the historical examination number of the medical institution.
For example, the setting process of the number threshold may include the following steps:
acquiring the total times of examination items of the medical institution within the preset time according to the diagnosis and treatment data label;
the total number of examination items of the medical institution is a result obtained by adding all examination times of all departments of all users in a preset time, and represents the number of examination items of the medical institution in a certain preset time. In the present embodiment, the examination data is obtained according to all the clinical data tags in the dimension of issuing examination items, or the examination times of all the users in a preset time may be added.
And multiplying the total times of the inspection items by a preset proportion to obtain a time threshold value.
It should be noted that the preset ratio is set by the third party according to actual needs, and generally, the preset ratio corresponding to all medical institutions is the same, for example, the preset ratio is 80%, and when the total number of times of the examination items is equal to 400, the number threshold is equal to 400 × 80% — 320. Whether the checking times of a single user exceed the standard or not is measured through the total times of the acquired checking items, and the illegal behaviors of excessive checking times generated by medical institutions in the checking process of some users can be highlighted.
And step S40, when the number of times of examination of any user in the preset time exceeds a threshold number, determining that the medical institution has illegal action of issuing examination items.
If the number of times of examination of any user in the preset time exceeds the threshold number of times, the medical institution is considered to perform arbitrage behavior by opening examination items according to the information of the user, and the medical institution opening the examination items is confirmed to have illegal action of opening the examination items. And when the judgment result of the step S30 is that the number of times of examination of all users in the preset time does not exceed the number threshold, determining that the medical institution does not have the behavior of violation of issuing examination items.
According to the embodiment, diagnosis and treatment data uploaded by a medical institution are acquired and used as input of a preset data identification model for prediction and identification, so that a diagnosis and treatment data label is obtained; acquiring the number of times of examination of each user in preset time from the diagnosis and treatment data label; judging whether the checking frequency of any user in the preset time exceeds a frequency threshold value; and when the number of times of examination of any user in the preset time exceeds a threshold number, determining that the medical institution has illegal action of taking examination items. Therefore, on the basis that the preset data identification model based on the machine learning algorithm is used as the prediction model to obtain the diagnosis and treatment data labels, the examination times of the user in the medical institution, which are obtained according to the diagnosis and treatment data labels, are compared with the time threshold value to determine whether the medical institution has the behavior of opening examination and inspection items in violation, the behavior that the medical institution carries out cash register on the more examination items of the user can be found, the waste of medical insurance overall planning funds is reduced, and the decision is intelligent.
Optionally, when the number threshold is used for detection, the following abnormality recognition algorithm may be used for detection, including: dividing all diagnosis and treatment data labels related to the opening examination items obtained through a preset data identification model as a data space, wherein the side length of the data space is equal to d/(2 x k)1/2) The unit (2). Each cell having two layers surrounding it, the first layer having a thickness of one cell and the second layer having a thickness of int 2 k1/2-1]. The algorithm counts outliers on a cell-by-cell basis rather than on an object-by-object basis. For a given cell, it accumulates three counts: the number of objects in the cell (cell _ count), the number of cells and objects in the first layer (cell _ +_1_ layer _ count), the number of cells and objects in the two layers (cell _ +_2_ layers _ count). If cell _ +_1_ layer _ count>M, all objects in a cell are not abnormal; if cell _ + _2_ layers _ count<All objects in a cell are abnormal; otherwise, some of the data in the cell may be anomalous. The algorithm changes the detection of the abnormal point data of each element in the data space into the detection of the abnormal point data of each unit, thereby improving the efficiency of abnormal recognition.
Further, in other embodiments, the step S40 includes:
step S41, when the number of times of examination of any user in the preset time exceeds a threshold value, acquiring the historical number of times of examination of the medical institution; evaluating whether the medical institution meets the exemption condition of the times of preset inspection items or not according to the historical inspection times of the medical institution; if not, go to step S42; if yes, go to step S43;
the number of medical institution examinations acquired may be the number of medical institution examinations over the years. The condition of exemption of the number of times of the preset examination items can be set according to actual needs, for example, the number of times of the examination items of the medical institution does not exceed a first preset limit value in the last 5 years, or the number of times of the month average examination items of the medical institution does not exceed a second preset limit value in the past years, and the like.
Step S42, determining that the medical institution has illegal opening examination item behaviors;
if the medical institution does not meet the exemption condition, the medical institution is not considered to be the medical institution in a special position or under the special condition, and the number of times of examination of any user in the medical institution within the preset time exceeds the threshold number of times, so that the medical institution has the behavior of violating the examination item.
Step S43, determining that the medical institution does not have the illegal opening examination item behavior.
Because the medical institution meets the exemption condition, the medical institution can be considered as a medical institution at a special position or under a special condition, and the condition that the number of times of examination exceeds the threshold number of times possibly exists in a certain patient due to the requirements of the disease condition. The number threshold is determined by multiplying the total number of examinations in a preset time by a preset proportion in the medical institution, and the overall examination base number of the medical institution is small, so that once a certain patient needs to be detected for many times due to the condition, the examination number of the patient is easily larger than the number threshold.
And further acquiring a diagnosis report of the patient, determining whether the suspicion of the illegal opening examination item behaviors can be eliminated, and if the medical institution determines that the medical institution does not need to open the examination for the patient for multiple times according to the diagnosis report of the patient, determining that the illegal opening examination item behaviors exist in the medical institution. Otherwise, the behavior that the medical institution illegally opens the examination item is eliminated. Through presetting the exemption conditions of the times of the examination items, the number of the annual examination times of the medical institution which helps to eliminate special conditions is small, so that the condition that the number of times of the annual examination of part of patients exceeds the threshold value of the times of the annual examination is needed to be examined for many times due to the disease conditions, and the condition that the detection is inaccurate due to the occurrence of the special conditions is prevented.
Further, referring to fig. 3, in another embodiment, before the step S30, the method further includes:
step S21, acquiring the institution level of the medical institution;
the institution level of the medical institution may be an index for the state or region to evaluate the hospital qualification according to the hospital function, facility, technical strength, etc., for example, the medical institution in the continental area of china is classified into three grades and ten grades through evaluation.
In this embodiment, the method for acquiring the institution level of the medical institution may be to acquire a name or a font size of the medical institution, and search for the institution level of the medical institution from a preset database according to the name or the font size, where the preset database stores all the names/font sizes of the medical institution and corresponding institution levels. Alternatively, the institution level of the medical institution may be known from the medical institution's website and referral.
Step S22, acquiring a frequency threshold corresponding to the institution level according to the institution level of the medical institution, wherein the frequency threshold of the medical institution with low institution level is smaller than the frequency threshold of the medical institution with high institution level.
The corresponding times threshold value may be set in advance according to all the institution levels, and then the times threshold value of the medical institution may be obtained after confirming the institution level of the medical institution. It can be understood that, because the medical institutions integrating the functions, facilities and technical strength of the hospital are advanced, there is a great difference in the practical aspect compared with the medical institutions with low institution level, so that the user is more willing to select the medical institution with high institution level in the medical treatment process, and therefore, the higher the institution level of the medical institution in the actual operation process is, the larger the corresponding time threshold value is. The technical scheme of this embodiment is favorable to carrying out different number of times threshold value to the medical institution of different mechanism grades and prescribes a limit, has increased the humanized setting of check out test set, also more closely detects actual conditions.
Alternatively, the number threshold may be further set in combination with the province of the medical institution, that is, the number threshold of the examination items may be different for medical institutions of the same level in different provinces. For example, the threshold number of times in a medical facility with a large province of the standing population must be greater than the province with a small number of standing populations. Furthermore, the threshold value of the times of opening examination items of the famous hospital can be increased. The further protection of the scheme is beneficial to reasonably dividing the times threshold of the examination items aiming at medical institutions of various regions and grades.
The above step S22 may include the steps of:
step S221, determining a frequency threshold range corresponding to the mechanism grade according to the mechanism grade of the medical mechanism;
the scheme is that the mechanism grade and the total times of the inspection items in the preset time are combined to further determine the threshold value of the times. Each different institution level corresponds to a preset threshold range of times, which may be determined by collecting historical data of all medical institutions corresponding to the institution level.
Step S222, acquiring the total times of examination items of the medical institution in the preset time according to the diagnosis and treatment data label; judging whether a calculation result obtained by multiplying the total times of the inspection items by a preset proportion is within the time threshold value range or not; if not, go to step S223; if yes, go to step S224;
in practice, the total number of times of checking items in a preset time is used as a first priority reference factor for determining the threshold value of times, and the threshold range of times determined by historical data is used as a second priority reference factor. The number threshold may be determined by first multiplying the total number of examination items of the medical institution within a preset time by a preset ratio and then comparing the calculated product with the number threshold range.
Step S223, using the calculation result as the number threshold;
step S224, using the middle value of the frequency threshold range as the frequency threshold.
And if the calculation result is not in the range of the time threshold value, determining the time threshold value by using the first priority reference factor, namely using the calculation result as the time threshold value. And if the calculation result is within the frequency threshold range, correcting the calculation result by combining a second priority reference factor, namely taking the middle value of the frequency threshold range as the frequency threshold. The setting of the frequency threshold value is more accurate and appropriate by setting two reference factors of the frequency threshold value.
Optionally, with continuing reference to fig. 2, in another embodiment, after step S30, the method further includes:
step S50, when the number of times of examination of each user in the preset time does not exceed the threshold value of the number of times, obtaining the number of times of examination of each user in each department of the medical institution in the preset time according to the diagnosis and treatment data label;
this embodiment is a further comparison operation performed after comparing the number of overall examinations of each user at the medical institution. The examination times of each user in different departments in the dimension of the prescribed examination item can be obtained according to the diagnosis and treatment data label.
Step S60, acquiring historical examination times corresponding to each department of the medical institution, and determining an examination time threshold corresponding to each department according to the historical examination times corresponding to each department;
the historical examination times of each department of the medical institution can be directly obtained according to the diagnosis and treatment data labels of the medical institution in the past year, and can also be obtained according to report data disclosed by the medical institution. The setting of the inspection frequency threshold corresponding to each department may be set according to actual needs, for example, the historical inspection frequency of the last year of the last N years is selected, where N is an integer greater than 1, and the average value of the historical inspection frequency of the last year is taken as the inspection frequency threshold. Alternatively, the historical examination frequency of a department of N years may be randomly extracted, and the maximum value of the historical examination frequency may be used as the examination frequency threshold of the department. Alternatively, the result obtained by multiplying the average value or the maximum value of the obtained historical inspection times by a preset ratio may be used as the inspection time threshold.
Step S70, judging whether the checking frequency of each user in each department of the medical institution within the preset time exceeds the checking frequency threshold of the corresponding department;
step S80, when the number of times of examination of any user in any department of the medical institution exceeds the threshold value of the number of times of examination of the corresponding department within the preset time, determining that the medical institution has the behavior of illegal release examination items.
After the threshold of the number of times of examination in each department is determined, the processor of the detection device may compare the number of times of examination in each department of each user one by one, and as long as there is a fact that the number of times of examination in any department of one user exceeds the threshold of the number of times of examination in the department, it is considered that the medical institution has a behavior of violating the provision of examination items, and the department where the violation exists is the department where the number of times of examination in the preset time of the user exceeds the threshold of the number of times of examination in the process of comparing the number of times one by one.
According to the scheme, on the premise of comparing the overall examination times, the set examination time threshold of each department is compared with the examination times of each user in the department, and whether behaviors of illegal issuing examination items exist in each department of the medical institution or not is confirmed. The illegal action of a medical institution can be found in time, the waste of medical overall fund is reduced, the detection coverage range is wide, and the illegal action occurrence position can be found quickly.
Further, referring to fig. 4, in a further embodiment, the step S10 includes:
step S11, acquiring diagnosis and treatment data uploaded by a medical institution;
the implementation process of acquiring the diagnosis and treatment data uploaded by the medical institution in this embodiment is the same as that in the foregoing embodiment, and is not described herein again.
Step S12, according to a preset noise entity dictionary in a preset data recognition model, screening noise text data in the diagnosis and treatment data to obtain standard diagnosis and treatment data;
the preset noise entity dictionary is obtained by training in advance, and noise text data, such as a mark-up symbol, a comment text and js (javascript) code, is stored in the preset noise entity dictionary. And iterating the diagnosis and treatment data according to the noise entity dictionary to eliminate the noise text data in the diagnosis and treatment data, namely outputting standard diagnosis and treatment data of the noise-free text data, and realizing the standard text field matching of the diagnosis and treatment data.
Step S13, performing word segmentation on the standard diagnosis and treatment data to obtain a plurality of diagnosis and treatment text word segments, and converting each diagnosis and treatment text word segment into a corresponding word vector;
the standard diagnosis and treatment data is a diagnosis and treatment text after noise elimination, the diagnosis and treatment text can be segmented into a plurality of diagnosis and treatment text segmentation words through word segmentation, and all diagnosis and treatment text segmentation words form a diagnosis and treatment text segmentation word set. The method for segmenting the standard diagnosis and treatment data can be executed by referring to the existing segmentation tools and segmentation algorithms, and is not described herein in detail.
After the standard diagnosis and treatment data are segmented, the diagnosis and treatment text segmentation can be subjected to word variant classification. Word variant classification refers to converting all differences of a clinical text participle into a standardized format. For example, words or words which do not exist in the standard semantic dictionary can be found from all diagnosis and treatment text participles and deleted or corrected by utilizing a preset standard semantic dictionary through a regular expression or manually writing dictionary fields. The word variant classification of all diagnosis and treatment text participles helps to better and more quickly identify the semantics of diagnosis and treatment data, and text standardization is realized.
In this embodiment, the diagnosis and treatment text participles may be vectorized to obtain a Word vector (Word embedding) corresponding to each diagnosis and treatment text participle. The word vector is a vector in which diagnosis and treatment text participles are mapped to real numbers, and can represent words and consider semantic distance.
Step S14, acquiring sequences of all word vectors, and coding all the word vectors through a bidirectional Recurrent Neural Network (RNN) model in a preset data recognition model according to the sequences of all the word vectors to form a text matrix;
the sequence of word vectors can be analogized to the arrangement sequence, in the scheme, a bidirectional RNN (recurrent neural Network) model is utilized, the sequence of sentences in the diagnosis and treatment text is taken as reference, and the word vectors after splitting and conversion are recoded and combined to form a text matrix. Each row of this text matrix represents the meaning of each word expressed in context, corresponding to a word vector.
The bidirectional RNN model is a neural network for processing sequence data, right connection can be established among neurons between layers, and after forward calculation and reverse calculation of word vectors in each line are carried out through the bidirectional RNN model, combined word vectors can be spliced according to the sequence of the word vectors corresponding to the original diagnosis and treatment text participles to obtain a complete text matrix or a sentence vector matrix.
Step S15, after compressing the text matrix into a diagnosis and treatment text vector, predicting through a prediction network in the preset data recognition model to obtain a diagnosis and treatment data label corresponding to the diagnosis and treatment text vector.
The text matrix can be compressed into diagnosis and treatment text vectors, and then the diagnosis and treatment text vectors are sent into a prediction network for prediction, so that the diagnosis and treatment data labels are obtained through learning. It should be noted that the diagnosis and treatment data label may be a series of data obtained by understanding the diagnosis and treatment text by the model, and the data may be divided into each diagnosis and treatment data label in the form of data generation time, and may be sorted by combining information of the user, the patient, and the like.
The prediction network can adopt a standard feedforward neural network structure, a recurrent neural network structure and the like. The simple prediction process of the scheme is to input the standardized field into an LTSM (Long Short-Term Memory network) to output continuous label characteristics, and the continuous label characteristics are operated through a feedforward neural network; meanwhile, the diagnosis and treatment text vector is also transmitted to a feedforward neural network to extract vector characteristics, and then the vector characteristics and the label characteristics are cascaded to form vector-label characteristics; and finally combining the vector-label combination characteristics with a diagnosis and treatment data label for prediction output.
According to the scheme, after noise is removed and diagnosis and treatment data are segmented and vectorized, the diagnosis and treatment data labels are obtained through encoding and prediction through a neural network according to a word vector sequence, the process of obtaining the diagnosis and treatment data labels through prediction and recognition through a preset data recognition model is given, diagnosis and treatment data including contents such as prescriptions issued by doctors, issued examination items and/or drug lists are matched into corresponding standardized fields, and the meaning of words in the diagnosis and treatment data in the text is reflected.
