Problems solved by technology

Although the above-mentioned technical solution can convert paper records into electronic records, it does not verify the converted electronic records. Once there is an information error caused by the conversion in the converted electronic record, the error cannot be verified. come out
In the process of treatment or research, if there is wrong information in the electronic case inquired by doctors, patients and researchers, it will cause misdiagnosis of patients in the process of treatment, and test data of clinical research or drug clinical trials. Inaccurate

Embodiment 1

[0046] The structure of the clinical case report form recognition system of the present invention, such as figure 1 As shown, it includes a first OCR module, a second OCR module and a verification module. in,

[0047] The first OCR module uses the first OCR algorithm to perform image and text recognition processing on the case report form image to obtain a first electronic case report form, and transmits the first electronic case report form to the verification module. The case report form is the original data and legal documents in the clinical research or drug clinical trial, which has a certain format and items, and all or part of the items need to be recorded by the subjects in the paper case report form Fill it out by hand. The image of the case report form is the image obtained after scanning or taking pictures of the paper case report form by electronic equipment such as a scanner or a digital camera. The present invention is aimed at the image of the case report form...

Embodiment 2

[0066] As a kind of clinical case report form identification method described in the present invention, such as figure 2 As shown, it includes the following steps,

[0067] S1: Receive the case report form image, perform image and text recognition processing on the case report form image to obtain a first electronic case report form, and output the first electronic case report form;

[0068] S2: Receive the case report form image identified in step S1, and perform image and text recognition processing on the case report form image using a recognition algorithm different from that in step S1 to obtain a second electronic case report form, and convert the second electronic case report form 2. Electronic case report form output;

[0069] S3: Receive the first electronic case report form and the second electronic case report form, and compare and verify the first electronic case report form and the second electronic case report form; if the first If the contents of the electron...

Abstract

The invention relates to a system and a method for recognizing clinical case report forms. The system is characterized in that a verification module comprises an electronic case report form comparison unit, and the electronic case report form comparison unit receives first electronic case report forms and second electronic case report forms which are transmitted by a first OCR (optical character recognition) module and a second OCR module, and compares and verifies the electronic case report forms which are transmitted by the first OCR module and the second OCR module. The system and the method have the advantages that outputted erroneous electronic case report forms can be effectively reduced while the efficiency of work for converting paper case report forms into the electronic report case forms can be improved, the accuracy of the system for recognizing the clinical case report forms can be improved, and the speed of the system for recognizing the clinical case report forms can be increased; the paper case report forms are recognized by the first OCR module and the second OCR module according to different algorithms respectively, so that the comparison accuracy of the electronic case report form comparison unit for comparing the first electronic case report forms to the second electronic case report forms can be improved.

Description

technical field [0001] The invention relates to an identification system and an identification method for converting a paper case report form into an electronic case report form, in particular to an identification system and an identification method for a clinical case report form, belonging to the technical field of electronic case report forms. Background technique [0002] In clinical research or drug clinical trials, it is often necessary to collect patient case report forms, and the case report forms used for statistical analysis in clinical research or drug clinical trials must be electronic case report forms. At present, in most clinical research data centers, the content of the paper case report form is input into the computer by manual entry to form an electronic case report form, and the clinical data are statistically analyzed. In order to ensure the accuracy of the data, it is usually necessary to enter twice or even three times, and compare the data entered each...
