Abstract
The aim of the research: To evaluate the effect of a mobile digital assistant on the quality of the basic cardiopulmonary resuscitation (CPR) algorithm performed by first-year medical students in a simulated environment.
Materials and methods. A single-center randomized controlled trial was conducted in 2024 with 196 firstyear students. Participants were randomized into an experimental group (n = 80), who performed CPR using a digital assistant, and a control group (n = 116), who performed resuscitation without it. CPR quality was assessed using AmbuMan® CPR trainers with digital feedback. Non-parametric statistical analysis was performed: the Mann-Whitney U-test was used for quantitative variables, and Fisher's exact test with odds ratios (OR) and 95% confidence intervals (CI) was used for qualitative variables.
Results. The use of the digital assistant led to a statistically significant increase in the time to chest compressions: the median in the experimental group was 97,0 seconds [interquartile range: 56,8–125,0] compared to 55,0 seconds [42,3–74,0] in the control group (p < 0,001). At the same time, participants in the digital assistant group were significantly more likely to correctly assess consciousness (75,0% vs. 61,2%; OR 1,90, 95% CI 1,01–3,57; p = 0,047) and breathing (81,2% vs. 50,9%; OR 4,19, 95% CI 2,14–8,17; p < 0,001). No statistically significant differences in the quality of compressions (depth, rate, recoil) or ventilations were found between the groups.
Conclusion. The digital assistant effectively improves the performance of the diagnostic steps of the CPR algorithm by medical students without clinical experience. However, its use is associated with a significant delay in the initiation of compressions, which is a critical negative effect that requires further optimization of the application interface and the development of specialized training protocols.
