N3.ODIA (N3. Exchange of instrumental research data)

Main article: Laboratory Information Systems (LIS, LIS)

The service "N3. Exchange of instrumental research data" ("N3. ODIA"), developed by the company "Netrica Medicine," combines information systems involved in the process of conducting instrumental research, and simplifies access to their results.

2021: Unified protocol of information exchange in "N3.ODIA"

According to information as of May 2021, the N3 service uses a patient-centered model for organizing information work. The results of the studies are uniquely correlated with the patient and can be included in the electronic medical record.

Along with laboratory studies, instrumental diagnostic methods are used in planned and preventive examinations, in the detection of diseases, to control their course, and to assess the effectiveness of therapy. They are carried out on special equipment that allows you to evaluate the state or operation of an organ or system.

The study usually involves several information systems at once. In the medical information system (MIS), the doctor forms a referral for research. The laboratory assistant inputs patient data and test parameters to the AWS of the diagnostic equipment. The results of the study - in most cases this medical image in a special format, accompanied by a doctor's opinion - are stored on a specialized server (PACS) locally in a medical institution or in the Central Archive of Medical Images (CAMI).

The problem is that the information support of instrumental diagnostic methods is often fragmented and disordered. It may depend on the requirements for recording patient information in a particular repository, on the competencies of medical personnel, or on the rules adopted in a particular medical organization. Finding the results of the necessary study - for example, when a patient visits another institution is difficult even if all medical images are stored in the CAMI. This situation can lead to an erroneous diagnosis or the need to conduct expensive procedures again.

The service "N3. Exchange of instrumental research data" ("N3. ODIA") is designed to solve this problem. According to the developers, the service provides all information systems participating in the process with a single information exchange protocol (API) based on the industry standard HL7 FHIR. Importantly, all data is structured around a patient who is uniquely identified across all systems at all stages of the process. For this, special "smart" algorithms are used - the so-called patient index.

The search for the patient in the CAMI thus becomes simple and fast, and if the MIS or RIS is fully integrated with the service, then the results of the study can be viewed without leaving the main system in the same window. The doctor sees all the available information: medical images, descriptions, conclusions and recommendations of specialists. The obtained data can be useful for refining the diagnosis and selection of optimal treatments, analyzing the dynamics of neoplasms.

The service "N3.ODIA" allows you to flexibly approach the process of conducting the study. For example, you can take a picture in one institution, and describe it in another. You can supplement the information on the study - add the so-called "second opinion" based on the results of viewing the picture by another doctor. In all cases, the service will combine information related to one study and provide it to the information system in which the attending doctor works. Thus, the service in the future can go beyond the region and is widely used to provide telemedicine services.

"Service" N3.ODIA "harmoniously combines the information systems of the region involved in supporting instrumental research, and is able to accumulate information about any research without restrictions: CT, MRI, X-ray, ultrasound, echocardiography, Holter monitoring and any others. We ensure complete continuity of data and transfer it to external information systems - including to the federal services of IEMC and REMD, VIMIS. At the same time, it doesn't matter what the study was, where and when it was done, how the patient's information was entered - all the data are grouped around the patient and available to the treating doctor, "said Igor Bashkov, commercial director of Netrika Medicine.
