Description
Technical field
The present invention relates to robot calculator field of information processing, particularly relate to a kind of intelligent diagnostics Operation encoding search method.
Background technology
International disease (operation) classification is some feature according to disease, according to rule, disease is classified, and by the system that represents of form of coding, to be the classification of diseases of international uniform that WHO formulates, to be the standardization of disease (operation) title, format be medical information, the basis of hospital information management (Taxonomic discussion below for disease name is applicable to operation names simultaneously).Different due to International Classification of Diseases and clinical disease naming system, make the entry of clinical disease title and International Classification of Diseases not man-to-man relation.Because in two systems, entry is numerous, even if for the disease code person (carrying out the staff of clinical International Classification of Diseases) of specialty, disease code (classification) still can run into a lot of difficulty.And for the clinician of non-coding specialty, then difficulty is larger.Along with the development of social security DRGs-based payment system (DRGs) and the reinforcement of Hospital Informatization, accurately carry out International Classification of Diseases demand more and more stronger, and for coder, health care worker, carry out International Classification of Diseases exactly and become a large hospital difficult problem.
The diagnosis coding retrieval scheme that Gong health care worker common at present uses is:
(1) retrieved by the Pinyin abbreviation of diagnosis, five codes, diagnosis words, and retrieval mode is key search.
As: need coding " K80.1 cholecystitis with cystic calculus " then need to fill in into such as " accompanying gallstones " or " calculus companion cholecystitis " mode retrieve the result set comprising target code.Having there is ground improvement project is by a point set of keyword, as passed through " cholelith is scorching " result set of searched targets coding.
Defect:
Even 1 by the scheme after improving: when retrieve in word there is the content word of non-targeted title time, then can not return correct objective result collection.As " calculus companion companion gallbladder inflammation ", " cholelith inflammation ", " stone courage inflammation ", four kinds of character strings of the correspondence of " calculous cholecystitis ", can not obtain the result set comprising correct " K80.1 cholecystitis with cystic calculus ".
2, the result set returned is too much: result set too much increases user in the difficulty selecting correct respective items, as contained 45 results by the result set of " cholelith is scorching ".
3, the result returned can not embody the correlativity of accuracy: in current query and search scheme, sequence only relies on Pinyin abbreviation or the stroke abbreviation sequence of title, the front and back of sequence and the title non-correlation that is retrieved, usually cause correct entry very rearward, add the difficulty of correct categorizing selection.
4, difficulty is used: health care worker, when retrieving, in order to allow result comprise target designation as far as possible, may adopt the least possible key word.Just there is skill set requirements in the selection of the key word to the character string be retrieved, usually needed doctor to participate in short-term cultivation and rely on long-term use experience to improve the ability of sorting code number, adding use difficulty.
(2) the another kind of International Classification of Diseases query and search scheme developed improves occurrence by the non-standard content increased in java standard library at present, and generically understanding is exactly the diagnosis name adding clinician directly to code database.As directly will " calculous cholecystitis " add inquiry storehouse corresponding " K80.1 " and in, make that " calculous cholecystitis " becomes and can be queried.
Defect:
1, still difficulty is used: the diagnosis form criteria of right and wrong of doctor, potential wrongly written or mispronounced characters, space, punctuate, diagnosis length all directly can have influence on result for retrieval.When this occurs, use key search scheme again, problem still.
2, lose standard: international disease storehouse is an international standard storehouse originally, the storehouse added voluntarily can be standardizedly variously lose meaning a little.Namely the design original intention of International Classification of Diseases has been run counter to.
3, implement difficulty large: clinical diagnosis entry is various, is the entry being far longer than International Classification of Diseases more than 20,000, complete this work and make it be applicable to clinically remain a huge task and challenge, taking time and effort.
In sum, present inventor, in the process realizing invention technical scheme in the embodiment of the present application, finds that above-mentioned technology at least exists following technical matters:
In the prior art, existing diagnosis coding search method exist use difficulty large, international standard can not be met, implement the large technical matters of difficulty.

When carrying out the selection of International Classification of Diseases for clinical diagnosis, according to diagnosis entry by the number of times once used, person raises match strength often;
For in operation or diagnosis, remove insignificant character in coding schedule, to adjust matching degree.
Further, in described removal coding schedule, insignificant character is specially:
During for clinical diagnosis, ignore obtaining "left", "right" in retrieval title, to adjust matching degree;
During for operation names, ignore obtaining " art " in retrieval title, to adjust matching degree;
Other are ignored relative to the insignificant character of code database;
During for operation names or diagnosis, removal unit divides specific punctuation mark, as: comma, branch, question mark etc.In step 4: the meaningless character in code database such as " art " in the "left", "right" in diagnosis and operation is ignored, when calculating the match strength of each set element of diagnosis or operation storehouse, can the impact that brings of these special characters of active balance.
Further, describedly based on presetting method, match strength to be adjusted, before can be used for results set process, in process and before returning.
Further, described step 4 also comprises step IV: the correlativity that match strength can add character sequence is carried out intensity and calculated.Intensity can be changed to 1.5 times by the character string met completely as order.
Further, when reception is retrieved character, subsidiary one or more restriction parameters can be accepted as required, return corresponding set.
Further, described step 5: the coded character set of temporary information to step 1 according to match strength set entry is sorted, and ranking functions can calculate, also can be screened by database SQL and draw.
The result set of specifying returns quantity and can set according to need of work.Significantly can expand for the character string that is difficult to be retrieved and return entry.
This method is not only applicable in international disease (operation) coded system, on other occasions, can change and be applicable in other character screening systems.
In the set of storehouse, single set comprises multiple character group, and the strength matching method multiple character group being applied simultaneously this system is carried out strength matching and carries out comprehensive reference; As, disease (operation) code database comprises (1) diagnosis (operation) name, (2) encode, (3) (operation) rank etc., character group is adopted to import into and carry out Strength co-mputation respectively when considering to import character into, comprehensive strength sorts, and returns the results set with multi-column data with this.
Import the removal that character should carry out repeat character (RPT) into, in actual test, the repeat character (RPT) repeatedly occurred can improve match strength strongly, and this can cause undesirable ranking results.
As required, this method can be arranged " callback method ", can carry out record when result set is selected, the result set returned can according to history access times minor sort again, with person easy to use.
When accepting to be retrieved character, can accept subsidiary one or more restriction parameters as required, accurately to return range of convergence, e.g., in disease code, when searching for neonatal disease code, additional parameter " P " only returns P class coding with clear and definite.
