Problems solved by technology

However, each study in clinical research involves a large number of indicators, ranging from hundreds to thousands. How to flexibly and efficiently extract relevant data from a large number of medical data is the key to the clinical research process. The existing general search or Although vertical search can search medical data based on text, this search method is not only inefficient, but also the search results are usually inaccurate or incomplete, making it difficult to achieve the expected results

Embodiment 1

[0051] Please refer to figure 1 , this embodiment shows the structural diagram of the flexible medical record data extraction system disclosed in the present application, the system includes a client 1, an application server 2 and a database server 3, the client 1 is a program that provides services for users, and it can be installed in On an independent computer device, the computer device where it is located establishes a communication connection with the application server 2, and the client 1 can also be directly installed on the application server 2, figure 1 Take this case for example. The application server 2 establishes a communication connection with the database server 3, and in order to ensure the data communication performance between the application server 2 and the database server 3, because the application server 2 and the database server 3 are usually established with a high-speed channel using a 10G network or optical fiber . The database server 3 is a device...

Embodiment 2

[0053] based on figure 1 As shown in the network architecture, this embodiment shows the flow of the flexible medical record data extraction method disclosed in this application. Before the medical record data extraction, two necessary preparation steps are required: storing data and establishing index files to be sorted, as follows :

[0054] The first part, data storage.

[0055] Since the medical record data is unstructured data, this application uses the document method to store the medical record data, and follows the PHR (Personal health record, personal health record platform) principle to store a document for each patient separately, that is, each patient corresponds to The medical record data are stored as a medical record document, and the storage formats of the medical record document include but are not limited to bson, json, xml and text. Due to the large number of patients in actual application, the number of medical record documents is also relatively large. T...

Embodiment 3

[0086] Please refer to Figure 4 , the application also discloses a database server, the database server is such as figure 1 Database server 3 in the system shown. This embodiment shows a structural diagram of a database server, and the database server may include or be divided into one or more program modules, and the one or more program modules are stored in a storage medium and executed by one or more processors , to execute the method performed by the database server in the flexible medical record data extraction method disclosed in Embodiment 2. The program module refers to a series of computer program instruction segments capable of completing specific functions, which is more suitable for describing the execution process of the database server than the program itself. The following description will specifically introduce each program module and its functions in this embodiment:

[0087] The document storage module 410 is used to store the medical record data correspondi...

Abstract

The invention discloses a flexible medical record data extraction method. System and database server, Relating to the technical field of medical treatment, According to the invention, data storage iscarried out according to a PHR principle; a single medical record is used as a data storage unit to facilitate subsequent data extraction; various indexes can be associated with various medical records by establishing index indexes; full scanning is avoided when searching is carried out according to data searching conditions; Related medical records can be efficiently and rapidly positioned, fields related to relevant indexes in the medical records can be further positioned after the medical records are positioned, then assignment judgment is conducted on the extracted fields, a result can bereturned, data extraction is completed, flexibility and high efficiency are achieved, and a technical basis is provided for statistical analysis of clinical research.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to a flexible medical record data extraction method, system and database server. Background technique [0002] With the successful implementation of information management methods such as HIS (Hospital Information System, hospital information system), LIS (Laboratory Information System, laboratory information system) and PACS (Picture Archiving and Communication Systems, image archiving and communication system) in hospitals, digital hospitals Gradually formed, a large amount of data under the condition of informatization provides a data basis for clinical research. However, each study in clinical research involves a large number of indicators, ranging from hundreds to thousands. How to flexibly and efficiently extract relevant data from a large number of medical data is the key to the clinical research process. The existing general search or Although vertical search can search me...
