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

[0052] The structure of clinical case data collection system of the present invention, as figure 1 As shown, including scanning device and identification device. in,

[0053] The scanning device is used to generate a case report form image by scanning the paper case report form, and send the case report form image to the identification device. The scanning device can be electronic equipment such as a scanner, a camera, etc. When a high-speed scanner or a high-speed camera is used, the overall acquisition speed of the system can be improved.

[0054] The recognition device receives the case report form image sent by the scanning device, and performs image and text recognition processing on the case report form image to obtain an electronic case report form; the recognition device further includes a first OCR module, a second OCR module and verification module. in,

[0055] The first OCR module uses the first OCR algorithm to perform image and text recognition processing on ...

Embodiment 2

[0074] As a kind of clinical case data collection method described in the present invention, such as figure 2 As shown, it includes the following steps,

[0075] S0: scan the paper case report form to generate a case report form image, and send the case report form image;

[0076] 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;

[0077] 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;

[0078] S3: Receive the first electronic case report form and the second electronic case report form, and compare and verify the first electro...

Abstract

The invention relates to a clinical case data collection system and method. A verification module of a recognition device comprises an electronic case report form comparison unit. The electronic case report form comparison unit receives a first electronic case report form sent by a first OCR module and a second electronic case report form sent by a second OCR module and compares the electronic case report forms sent by the first OCR module and the second OCR module. In this way, while the working efficiency of converting paper case report forms into electronic case report forms is improved, output of mistaken electronic case report forms is effectively reduced, and the accuracy and speed of the clinical case data collection system are improved. Moreover, the first OCR module and the second OCR module recognize the paper case report forms respectively through different algorithms, and therefore the accuracy of comparison between the first electronic case report form and the second electronic case report form through the electronic case report form comparison unit can be enhanced.

Description

[0001] This application is a divisional application with application number 201310300966.2; [0002] The filing date of the original application is: July 17, 2013; [0003] The title of the invention of the original application is: a clinical case data collection system and collection method. technical field [0004] The invention relates to a data collection system for converting a paper case report form into an electronic case report form, in particular to a clinical case data collection system, which belongs to the technical field of electronic case report forms. Background technique [0005] 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 ...
