Augmented reality for intramuscular injection training: a cluster randomized controlled trial

Background: The acquisition of clinical skills, such as intramuscular injection, is crucial in nursing education, traditionally taught through theory and practice. Recent studies suggest that augmented reality (AR) enhances students' learning. Aim: To evaluate the effect of an augmented reality application (ARSim2care) for training intramuscular injections technique among undergraduate nursing students. Methods: A cluster randomized controlled trial was conducted. A total of 72 nursing students participated in the study (32 in the intervention group and 40 in the control group). Sociodemographic variables and dependent variables such as knowledge, skills, satisfaction and self-confidence with learning were measured. Results: The groups showed statistically significant differences in age. Knowledge acquisition in the intervention group was 0.56 points higher, this difference was statistically significant. No significant differences were found in technical skills, satisfaction and self-confidence although both groups showed positive results. Conclusions: The ARSim2care application enhanced nursing students' theoretical knowledge of intramuscular injections, although no significant improvements in technical skills were observed. Augmented reality shows potential as an educational tool; however, further research is required to evaluate its long-term effectiveness.
