Virtual patients with cardiovascular pathology: technology for postgraduate medical education

Aim. To create a methodological base for distance learning of cardiology healthcare professionals — multimedia clinical diagnostic tasks.Material and methods. The interdisciplinary team used text and multimedia formats for clinical diagnostic data. Web technologies provided remote access to information located on the server.Results. The report presents the experience of the practical implementation of multimedia clinical diagnostic tasks in cardiology, including the augmented reality. The variability of presenting information to students is implemented in the multimedia clinical diagnostic tasks, which is integrated with the rating system for evaluating decisions. The solution paths are determined by the actions of the students in the trigger interactive blocks and is evaluated by the rating system. Personal rating is a numerical value that integrally characterizes the decisionmaking competence of students. The conversion of the quantitative rating into the conventional form (‘pass/fail’, ‘excellent’, ‘good’, ‘passing grade’) will be provided after the trial period of the software.Conclusion. The created Web service and computer simulations can become a methodological basis for the distance learning in cardiology. This technology can be in demand in the continuing medical education.

Aim. To formulate the methodology for developing the interactive virtual computer simulations with a rating assessment of trainees’ decisions and the capability of remote access.Material and Methods. The methods of knowledge engineering were used to extract and formalize expert knowledge about the structure, significance, and relevance of clinical diagnostic information. The materials for creating virtual computer simulations were based on texts from the archival medical records, laboratory data, and multimedia results of instrumental methods of study. A three-tier network architecture was applied to provide the capabilities of remote access. It was organizationally represented by three components: a client layer, a business logic layer, and a data layer. Data transfer was provided by the Web protocols while microservices represented the infrastructure.Results. The information was formalized and structured after expert analysis and identification of significant diagnostic and prognostic data. The process included defining the domain model, identifying the aggregates and connections between them, and designing software and user interfaces. Possible solutions for trainees are now presented in the form of interactive reference lists. The artifacts of the user’s work are saved in the storage represented by the module for working with the server file system and the object-relational database management system. Each task module contains static and interactive blocks of information. The purpose of static blocks is to provide trainees with the necessary information for making clinical and diagnostic decisions. The interactive blocks allow selecting one or more solutions from the list. The content and sequence of further information presentation are determined by the trainees’ answers to the questions of an interactive block. Trainees’ decision-making competencies are evaluated using the rating system. The final personal rating is calculated as a multiplication of all coefficients related to the trainees’ decisions. This approach integrates a rating system with the trajectory chosen by the trainee for task completion.Conclusions. The distance learning technologies, developed for clinical disciplines in this study, are quite new and innovative. The repository of virtual computer simulations is under development to improve the methodological support of remote clinical training.
