Embodiment 1

[0049] The structure of clinical case data collection system of the present invention, as figure 1 As shown, including scanning device and identification device. in,

[0050] 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.

[0051] 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,

[0052] The first OCR module uses the first OCR algorithm to perform image and text recognition processing on ...

Embodiment 2

[0071] 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,

[0072] S0: scan the paper case report form to generate a case report form image, and send the case report form image;

[0073] 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;

[0074] 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;

[0075] 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 system and a method for acquiring clinical case data. The system is characterized in that a verification module of a recognition device further 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 case report forms can be improved, the accuracy of the system for acquiring the clinical case data can be improved, and the speed of the system for acquiring the clinical case data 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 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 [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 time in order to correct the data errors introduced during the manual e...
