Description

Medical coding method and device
Technical Field
The present disclosure relates generally to the field of medical information technology. More particularly, the present disclosure relates to medical encoding methods and apparatus.
Background
Medical coding is an important step or key in the clinical trial data management process. The data to be encoded is usually from text content freely filled in during the collection of a Case Report Form (CRF), including the content of medical history, disease diagnosis, adverse events, combined medication, etc. of the patient. Because of the differences of researchers in regions, languages, nations, cultures, knowledge backgrounds and the like, certain differences exist in expression descriptions of the same term, and the aim of coding is to provide correct and reasonable analysis information for safety and curative effect data analysis of medicines through term standardization.
The traditional medical coding is generally off-line coding, firstly, a medical coder acquires an original data set in an electronic data capture system (Electronic Data Capture System, abbreviated as an EDC system) to be delivered to a technician, then the technician uses an SAS macro or other tools to automatically code data according to an official medical dictionary (such as WHODRUG and/or MedDRA), and a result file (comprising an automatic matching file and a non-automatic matching file) is generated and returned to the medical coder; and the medical encoder carries out manual encoding on the data which cannot be automatically encoded according to the official medical dictionary, then the data is transferred to the technician again, the technician merges the data and then transfers the data to the medical encoding auditor for auditing, the auditing is finished after the data passes through the encoding work, the files need to be transferred to the medical encoder again for encoding when the auditing is wrong, and the medical encoder carries out modification, and then the technician merges the data and transfers the data to the medical encoding auditor for auditing until all result files pass the auditing. When the EDC official medical dictionary version is upgraded or the EDC dataset is updated, the encoding work again enters the loop. The above steps are complicated in process, inconsistent coding results are easy to cause, manual coding results cannot be reused, when new test medical coding is started, the terms which are coded before other tests are finished but the official medical dictionary cannot be matched automatically still need to be coded manually again by medical coding staff, so that time cost and labor cost are greatly increased, and medical coding efficiency is reduced.

Preferably, comparing the variable name to be encoded with first term name information of a medical dictionary to obtain a first term name corresponding to the variable name to be encoded, and obtaining a first encoding result of the variable name to be encoded according to the first term name includes: matching the variable name to be encoded with first term name information of a medical dictionary to obtain a first term name completely matched with the variable name to be encoded; if the first term name only corresponds to one piece of medical dictionary information, the medical dictionary information corresponding to the first term name is used as the first coding result of the variable name to be coded; and if two or more pieces of medical dictionary information correspond to the first term name, acquiring one piece of medical dictionary information as the first coding result of the variable name to be coded according to a preset matching rule. It is to be understood that, in the embodiment of the present disclosure, the term name information is a set of term names, that is, a set of all term names in the medical dictionary is referred to as "term name information".
According to an embodiment of the present disclosure, the official medical dictionary may be MedDRA or WHODrug, wherein MedDRA (Medical Dictionary for Regulatory Activities, regulatory activity medical dictionary) is ICH (international human drug registration technology coordination association) international medical phrase dictionary, and the range of inclusion includes: signs and symptoms, diseases, diagnosis, indications of treatment, names of indications, qualitative results of physical and chemical examination, surgical and medical treatments, medical history, social history, family history, and the like; WHODRUG, broadly known as WHODRUG Global, is the most comprehensive electronic dictionary for pharmaceutical products, and comprises 4 kinds of dictionary of world health organization medicine dictionary (WHO-DD), world health organization medicine dictionary enhancement edition (WHO-DDE), world health organization herbal medicine dictionary (WHO-HD) and comprehensive dictionary (Combined dictionary). The official medical dictionary is subjected to data processing to form one or more medical dictionary data tables for storage so as to facilitate medical coding. In the embodiments of the present disclosure, the "medical dictionary" refers specifically to one or more medical dictionary data tables formed by data processing of an official medical dictionary.
Specifically, taking MedDRA as an example, an official medical dictionary file is obtained, and decompressed, core files therein, such as an mdhier dictionary file (mdhier. Asc) and an ae_llt dictionary file (LLT. Asc), are obtained, information of the core files is extracted in units of rows, and the extracted information is subjected to segmentation extraction according to preset separators to obtain required key information, and one or more medical dictionary data tables are formed and stored according to a correspondence combination between the information to obtain a medical dictionary corresponding to MedDRA (hereinafter referred to as "MedDRA medical dictionary") in the embodiment of the present disclosure.
Illustrating:
for example, a line of text in mdhier. Asc is: "10000002$10021608$10021605$10027433$11-beta-hydroxylase lacks the abnormal synthesis of various kinds of sterols $congenital metabolic disorder $metabolic and nutritional disorder $metab$10010331$n$", and after division by "$" symbol, it is split into: 1- "10000002", 2- "10021608", 3- "10021605", 4- "10027433", 5- "11- β -hydroxylase deficiency", 6- "abnormal synthesis of various sterols", 7- "congenital metabolic abnormal disease", 8- "metabolic and nutritional disease", 9- "Metab", 10- ", 11-"10010331", 12-" N ", and 12-" total 12 character strings stored in the m_ae_mder table according to the corresponding rules of 1-PtCode (preferred language code), 2-hltecode (higher language code), 3-HlgtCode (higher language code), 4-SocCode (system organ classification code), 5-PtName (preferred language name), 6-HltName (higher language name), 7-HlgtName (higher language name), 8-SocName (system organ classification name).
Similarly, for example, a line of text in llt.asc is: "10000001$" gas exchange "pneumonia $10081988$$ $ N $ divided into: 1- "10000001", 2- "gas exchange" pneumonia ", 3-"10081988", 4-", 5- ", 6-", 7- ", 8-", 9- ", 10-" N ", 11-", 11 total character strings, which are stored in the m_ae_llt table according to the corresponding rules of 1-ltcode (lower language code), 2-ltname (lower language name), 3-PtCode (preferred language code).
It should be noted that the above examples only exemplify a part of the corresponding rules of the key information, wherein the low-level words (Llt, lowest level terms) are synonymous words in medicine, which describe specific events in the most detailed language, and different expressions of spoken words and events specific to a certain language can only be found in this hierarchy; the Preferred term (Pt) is used to express unique and clear medical concepts, is a basic term for international medical information exchange, and has no limitation on the number of low-order terms in the Preferred term; high level terms (Hlt) categorize the preferred terms in a variety of ways, such as anatomically, pathologically, biologically, etiologically, physiologically functional, etc., for retrieval, categorization; the high-level group language (Hlgt, high level group terms) is a broader concept above Hlt; the system organ classification (Soc, system organ class) corresponds to the system classification in other medical terms, and the preferred language may be connected to at least one Soc; if there is no character or space between the two separators "$", the extracted information is listed as "empty" or discarded. In addition to the above key information, the related character strings extracted from the official medical dictionary may be listed in the corresponding medical dictionary data table or discarded according to a preset rule, and will not be described herein. The above examples are only examples and are not limiting on the technical solutions of the present disclosure.
It may be understood that after extracting key information from different core files in the medical dictionary file of the official party, different medical dictionary data tables may be formed and stored according to the corresponding information relationship, and the key information may be integrated into one medical dictionary data table according to the corresponding information relationship in the above embodiment, which is not limited herein.
For the coding of "adverse reaction/adverse event, disease" etc., a medical dictionary corresponding to MedDRA may be employed. Specifically, the variable name to be encoded is matched with the ltname information (i.e., the first term name information) in the m_ae_llt table, so as to obtain a low-level language name (i.e., the first term name) which is completely matched with the variable name to be encoded, and if the low-level language name corresponds to only one piece of medical dictionary information, the piece of medical dictionary information is included: ptCode, lltCode corresponding to the low-level language name in the M_AE_LLT table, hltCode, hltName, hlgtCode, hlgtName, socCode, socName and the like in the corresponding M_AE_MDHIER table are used as the coding results of the variable name to be coded; if the low-level language names correspond to a plurality of pieces of medical dictionary information, preferentially acquiring an M_AE_MDHIER data set of PtName in an M_AE_MDHIER table and the name of a variable to be encoded, then finding out data of LtCode in the M_AE_LLT table and PtCode in the M_AE_MDHIER data set, and taking the finally acquired piece of medical dictionary information as an encoding result of the variable name to be encoded; if the required medical dictionary information cannot be obtained by adopting the matching rule, ptCode of the first piece of M_AE_LLT data in the data set with the consistent name of the variable to be encoded in the M_AE_LLT table and PtCode in the M_AE_MDHIER table can be selected for matching, and the obtained piece of data dictionary information is used as the encoding result of the variable name to be encoded. If the coding result can not be obtained after the processing, the matching is failed, and the subsequent further coding can be performed through the synonym library.
Taking WHODrug as an example, an official medical dictionary file is obtained, and decompressed, and core files, such as a DD dictionary file (DD. Txt), a DDA dictionary file (DDA. Txt), and an INA dictionary file (INA. Txt), are obtained, information of the core file is extracted in units of lines, and the extracted information is extracted in a splitting manner according to a preset field to obtain required key information, and one or more medical dictionary data tables are formed and stored in combination according to a correspondence between the information, so as to obtain a medical dictionary corresponding to the WHODrug (hereinafter referred to as a "WHODrug medical dictionary") in the embodiment of the disclosure.
Illustrating:
for example, a line of text in DD.txt is: "000001010024T20KEN 01041ALDOMET [ methyldopa ]", the first 11 characters "00000101002" are extracted to correspond to the drug code field in the W_DD table, the 31 st character from the beginning to the end of the characters "ALDOMET [ methyldopa ]" are extracted to correspond to the product name field in the W_DD table, and the extracted characters are stored in the W_DD table.
Similarly, for example, a line of text in dda.txt: "000017040015S02AA", extracting the first 11 characters "00001704001" corresponding to the drug code field in the W_DDA table, 13 th-17 th characters "S02AA" corresponding to the ATCCode field in the W_DDA table, 13 th-15 th characters "S02" corresponding to the ATCCode1 field in the W_DDA table, 13 th-15 th characters "S02" corresponding to the ATCCode2 field in the W_DDA table, 13 th-16 th characters "S02A" corresponding to the ATCCode3 field in the W_DDA table, 13 th-17 th characters "S02AA" corresponding to the ATCCode4 field in the W_DDA table, and storing all the extracted characters in the W_DDA table.
Likewise, a line of text in INA. Txt: the "A01AB 4 oral topical anti-infective and antibacterial drug" extracts the first 7 characters, "A01AB" corresponding to the ATCCode field in the W_INA table, the 8 th character, "4" corresponding to the LevelCode field in the W_INA table, the 9 th character to the end "oral topical corticosteroid drug" corresponding to the ATCCtext field in the W_INA table.
It should be noted that the above examples are only examples to illustrate the method for establishing the medical dictionary corresponding to the WHODrug, and are not limiting on the technical solution of the present disclosure. Wherein, when extracting information in line units for the medical dictionary file, each space in each line of text is counted as a character; ATC classification (anatomic-therapeutic-chemical classification) is a drug classification system employed by WHODrug that classifies all drugs into 14 major classes (ATCCode 1) according to their anatomic organs/systems of treatment, then reclassifies according to pharmacology/therapeutics (ATCCode 2), ATCCode3 and ATCCode4 continuing to classify drugs into different subclasses according to chemistry/pharmacology/therapeutics.
It may be understood that after extracting key information from different core files in the medical dictionary file of the official party, different medical dictionary data tables may be formed and stored according to the corresponding information relationship, and the key information may be integrated into one medical dictionary data table according to the corresponding information relationship in the above embodiment, which is not limited herein.
The medicine/drug is coded, and a corresponding medical dictionary of WHODrug can be adopted. Specifically, the variable name to be encoded is matched with the product name information (i.e. the first term name information) in the w_dd table, so as to obtain a drug name (i.e. the term name) completely matched with the variable name to be encoded, and if the drug name corresponds to only one piece of medical dictionary information, the piece of medical dictionary information is included in the following steps: drugCode, productName, preferredCode, preferredName, ATCCode1, ATCCode2, ATCCode3, ATCCode4, etc. as the encoding result of the variable name to be encoded; wherein, the PreferredCode is the code obtained by replacing the three digits of the drug code in the W_DD table with "001", and the PreferredName is the product name of the first piece of data of which the drug code in the W_DD table is matched with the PreferredCode. If the drug name corresponds to a plurality of pieces of medical dictionary information, for example, a plurality of atccodes, an appropriate ATCCode may be selected according to the purpose of administration, indication, etc., and the corresponding whole piece of medical dictionary information may be used as the encoding result of the variable name to be encoded. If the ProducName matching the variable name to be encoded is not obtained, the encoding of the medical dictionary fails and can be further encoded through a synonym library later.
In step S103, when the first encoding result of the variable name to be encoded is not obtained in the medical dictionary, the variable name to be encoded may be compared with the expanded term information of the synonym library, so as to obtain a second term name corresponding to the variable name to be encoded, and a second encoding result of the variable name to be encoded may be obtained according to the second term name; the second encoding result is a piece of medical dictionary information corresponding to the second term name in the medical dictionary.
According to an embodiment of the present disclosure, in order to ensure uniformity and normalization of encoding, the synonym library corresponds to the medical dictionary, the synonym library includes extended term information and second term name information, the extended term information corresponds to the second term name information, and the second term name information corresponds to the first term name information in the medical dictionary. The second term name information of the synonym library in the embodiment of the disclosure is derived from the first term name information of the corresponding medical dictionary, so that the synonym library is strongly related to the corresponding medical dictionary, and the synonym library is convenient for subsequent medical coding use.
