Description
Technical field
The present invention relates to the papery CRF is converted to the data acquisition system (DAS) of electronic medical records account, specifically a kind of clinical case data acquisition system (DAS), belong to electronic medical records account technical field.
Background technology
In clinical research or clinical drug trial, often will collect patient's CRF, and the CRF that is used for statistical study in clinical research or clinical drug trial must be the electronic medical records account.At present, in most of clinical research data center, or the mode by manual typing is carried out statistical study by formation electronic medical records account in papery CRF content input computing machine to clinical data.In order to guarantee the accuracy of data, usually need to be through even three typings of twice typing, and the data of each typing are compared to correcting the error in data because introducing in the manual entry process.Because the data management pilot process has a large amount of manual interventions, work efficiency is limited, and the possibility that data make a mistake also can increase exponentially, and, in order to eliminate this mistake, has to again increase more manpower.
Chinese patent CN102968572A discloses a kind of orthopaedics case information acquisition system and acquisition method thereof, wherein, described orthopaedics case information acquisition system comprises papery case scanning collection module, electronic medical records automatic converting module, orthopaedics image collecting module and case information shared platform; Wherein, described papery case scanning collection module comprises: scan module, image processor word identification module, data poke module and data transmission interface, described scan module comprises high speed scanner, scan module is converted to image information by patient's papery case information, image is processed and the word identification module is file scanning software, converts the image information of scanning to the electronic medical records text; Described electronic medical records automatic converting module comprises: HL7 resource module, HL7 send and accept module lighting module, HL7 modular converter, HL7 AIM and HL7 information; Described orthopaedics image collecting module comprises: acquisition module, memory module and data transmission interface.Described case information shared platform comprises: papery case information interface, electronic medical records information interface, orthopaedics image information data-interface, data processing module, data poke module and data sharing module.Described orthopaedics case information acquisition method comprises the steps: that (1) gathers papery orthopaedics case information by papery case scanning collection module; (2) gather orthopaedics electronic medical records information by the electronic medical records automatic converting module; (3) gather the orthopaedics image information by the orthopaedics image collecting module; (4) information exchange of above-mentioned steps collection is crossed to internet transmission to the case information shared platform; (5) data sharing platform is collected, is arranged case information, and offers doctor and patient's inquiry.Although technique scheme can be converted to electronic medical records by the papery case, the electronic medical records after conversion is not carried out to verification, once there be the information errors caused because of conversion in the electronic medical records of changing, this mistake just can not be by verification out.When in treatment or research process, if there is wrong information in the electronic medical records of inquiring about for doctor, patient and researchist, can causes to patient mistaken diagnosis in therapeutic process, to clinical research or clinical drug trial, cause test figure inaccurate.

S51: receive described the first transient state electronic medical records account, and the statement in described the first transient state electronic medical records account is carried out to syntax check, if the syntax check result is correctly exported described transient state CRF as the second transient state electronic medical records account; Otherwise will in described the first transient state electronic medical records account, through the incorrect place of syntax check, carry out exporting after the grammar mistake mark;
S52: receive described the first transient state electronic medical records account of exporting after the grammar mistake mark, and the content of grammar mistake mark on described the first transient state electronic medical records account is carried out to artificial nucleus couple, using the artificial nucleus to after described the first transient state electronic medical records account as the second transient state electronic medical records account, export.
7. a kind of clinical case collecting method according to claim 6, is characterized in that, also comprises the step that phrase is checked after described syntax check step:
S61: receive described the second transient state electronic medical records account, statement in described the second transient state electronic medical records account is carried out to random intercepting and obtain random phrase, and described random phrase is inquired about in predetermined database, if described random phrase is the key words stored in described database or key sentence all or part of, described the second transient state electronic medical records account is exported as final state electronic medical records account; Otherwise, the described random phrase intercepted in described the second transient state electronic medical records account is carried out after error flag checked in phrase exporting;
S62: receive phrase and check described the second transient state electronic medical records account of exporting after error flag, and the described random phrase that error flag checked in phrase in described the second transient state electronic medical records account is carried out to artificial nucleus couple, using the artificial nucleus to after described the second transient state electronic medical records account as final state electronic medical records account, export.
8. a kind of clinical case collecting method according to claim 7, is characterized in that, the database in described step S61 generates according to following steps:
S5 ' 1: store predetermined key words and key sentence into database;
S5 ' 2: record the number of times of described random phrase accessing database, if number of times surpasses predetermined n time, using described random phrase as key words or key sentence store in described database.
