Spots Global Cancer Trial Database for Experiment on the Use of Innovative Computer Vision Technologies for Analysis of Medical Images in the Moscow Healthcare System

Study Description

Brief Summary: It is planned to integrate various services based on computer vision technologies for analysis of the certain type of x-ray study into Moscow Unified Radiological Information Service (hereinafter referred to as URIS). As a result of using computer vision-based services, it is expected: 1. Reducing the number of false negative and false positive diagnoses; 2. Reducing the time between conducting a study and obtaining a report by the referring physician; 3. Increasing the average number of radiology reports provided by a radiologist per shift.

Detailed Description: Recently a growth in the number of radiology studies across multiple modalities has been observed alongside the modest increase in staffing levels. This carries higher risks of increased workload and efficiency losses. The integration of computer vision-based services into URIS will improve the radiologists' productivity and job performance. Existing prerequisites for conducting the study: 1. Increasing the number of preventive and diagnostic radiological studies entails the growing workload for radiologists and increased risk of interpretation errors, which in turn leads to the decrease in quality of medical care. 2. When a radiologist opens a worklist of studies, in the absence of special notes, he/she writes a report in the random order, not being able to select from the list the studies that require the most attention and prompt response (studies with pathological findings), which increases the time of diagnosis. 3. The absence of the structured pre-filled template of report leads to the increase in time for preparing reports. 4. A radiologist has to spend considerable time evaluating the dynamics of pathological changes, which also increases the time to prepare a report as well as the risk of error. 5. Interpretation of preventive studies requires double reading, which is implemented inefficiently due to the staff shortage. Study objectives: 1. Study the diagnostic accuracy of the Services in accordance with the methodological guidelines No. 43 "Clinical trials of software based on intelligent technologies (diagnostic radiology)" (recommended by the Expert Council on Science of the Moscow Healthcare Department, Protocol No. 8 of June 25, 2019). 2. Audit the studies conducted with Services application in order to determine the number of interpretation errors, and compare it with the audit result without their application (hypothesis 1). 3. Conduct timekeeping to estimate time for preparing a report and the total number of evaluated studies with and without using the Services (hypothesis 2,3). 4. Conduct a survey of radiologists who use the Services in their work, in order to determine their opinion about the implementation of innovative technologies in the diagnostic process. METHODOLOGY 1.

For each Service, the participation process in the Experiment consists of the following stages: 1. selection; 2. the preparatory stage; 3. the main stage; 4. the final stage. During the Experiment, a radiologist will routinely be able to: * work on a sorted list of patients (triage); * work with images processed by the Service; * work with a pre-filled template of the radiological report on each study; * evaluate the work of the Service according to the developed questionnaire. During the Experiment, a patient will receive the individual plan of the follow-up support. It includes preventive examinations or observation as well as treatment by a specialist. Systematization and final analysis of the Experiment results is carried out within three months from the completion date of the last Service participation in the Experiment. Based on the results of the Experiment, recommendations can be prepared on the possibility to register certain services as a medical device (software).
