Background. Anxiety among medical professionals is a significant factor determining the success of a doctor’s actions. Anxiety management skills are important in situations when a doctor has limited time to make decisions in a critical condition of a patient, in the case of severe pain syndrome, when «hidden» or «erased» symptoms of a disease are present and in other conditions that require close attention. Multiple training sessions on simulators with the solution of professional cases in situations similar to real ones could be the way to develop anxiety management skills. In the process of case solving, the student, faced with anxiety, is able to develop skills in managing his own anxiety. Modern technologies of virtual and mixed reality can be a significant technological addition to classical simulation training. However, before actively implementing such technologies, it is advisable to make sure whether training on virtual and mixed reality simulators affects the level of anxiety of the course participant.
Aim. The main goal of the study is to explore the indicators of state anxiety (SA) before and after working on a mixed reality simulator during the educational process aimed at developing students’ skills in medical examination and diagnosis of patients with acute abdominal pathology.
Material and methods. A prospective, randomized, controlled study with blinded data analysis took place during the period from November 2023 to December 2024. The research participants (RP) were volunteers from 4th-year students of the Faculty of Medicine (n=93) who completed the mandatory stage of training at the Department of Faculty Surgery (clinical department) according to the approved program. The scenarios were created on the basis of a patient examination model in the emergency room. The examination and diagnosis were carried out by the RP on a standardized patient (SP), which simulated patients with various cases of acute abdominal pathology. Before the SP examination, the RP of the 1st group underwent one-time training in virtual reality using the cases of the XR-Body mixed reality simulator (LLC BMS/LLC GEOTAR-MED), which uses mixed virtual reality technology to train the skills of physical examination and examination of patients with symptoms of acute abdomen. To assess the level of trait and state anxiety of the participants, the Spielberger anxiety scale (State-Trait Anxiety Inventory – STAI) adapted by Y. Khanin was used. Before going through the virtual case and working with a standardized patient, the participants’ state anxiety levels were measured using the Spielberger–Khanin questionnaire; during the first measurement, a measurement was also taken on the scale of trait anxiety. Statistical analysis was performed using the Statistica software package. The main methods of comparative data analysis used were the Wilcoxon test and/or the sign test. The results are presented as M±SD, where M is the arithmetic mean, SD is the standard deviation; Me is the median, CI is the confidence intervals, including the values of the minimum to maximum values (min & max) or 10, 25–90, 75 percentiles for an informative presentation of the studied sample. Dichotomous and ordinal qualitative data are expressed as frequencies (n) and percentage distribution of features. The difference was considered statistically significant at p<0.05.
Results. The study groups had no significant differences in age, education level, gender and experience of examining patients with acute abdominal pathology. The RP of 1st group, whose reactive anxiety level decreased after working on the simulator, was 73,9%; in 19,6% of RP, the SA level increased, and in 6.5%, it did not change [before working on the simulator: M1 38.08, CI (5–95%) 35–42; after working on the simulator: M2=32.82, CI (5–95%) 30–36; p=0.0002]. Calculation of individual shifts in reactive anxiety among RP with a decreased SA indicator showed that in 32.4% of RP, the SA indicator decreased by up to 5 points; the reactive anxiety indicator decreased by 5 points or more in 29.4% of RP; by 10 points or more – in 38.2%. Analysis of the responses of the research participants regarding the change in the choice of answer options before and after working on the simulator in order to determine the direction of the shift for each question showed: a) a significant increase in the frequency of positive assessments by the participants of their condition and absence of anxiety at the moment [Me=7.5, CI (5–95%) 7–12, Q1–Q3 7–9 vs Me=15.5, CI (5–95%) 14–22, Q1–Q3 15–21; p=0.005]; b) a significant increase in the frequency of denial of the presence of anxiety at the moment [Me=37, CI (5–95%) 33–42, Q1–Q3 34–43 vs Me=40, CI (5–95%) 36–44, Q1–Q3 39–44; p=0.044].
Conclusion. In 74% of the research participants who underwent training in virtual reality conditions on the XR-Body simulator before examining a standardized patient, state anxiety statistically significantly decreased, with 68% of the study participants demonstrating a decrease in the state anxiety index by more than 5 points.
After training on the XR-Body simulator, the study participants statistically significantly more often assessed their own current state as stable and calm; all study participants after working on the simulator had a more confident assessment of their condition as calm and positive of up to 30%.
Study participants, after training in virtual reality conditions on the cases of the XR-Body simulator, statistically significantly more often denied the presence of an anxious state, with a positive shift of up to 15% from the initial value.
