Abstract

Introduction: Today, the use of new technologies has expanded in various fields. One of these cases is the use of smartphones and barcode reader software and two-dimensional barcodes. In this study, we tried to evaluate the influence of barcode utilization in the training of residents.

Methods: This was a descriptive cross-sectional study conducted in the emergency department of Ghaem Hospital, in which the effect of using educational barcodes on 30 medical residents of the emergency, internal medicine, and neurology was investigated. A questionnaire recording the performance of residents in medical emergency procedures was used. Also, demographic variables of residents were recorded. Data analysis was performed using descriptive and inferential statistics in SPSS software.

Results: A total of 30 residents completed the study questionnaire before installing the poster, and 29 of them completed the post-test questionnaire. Of these, 10 (33.3%) were emergency medicine residents, 13 (43.3%) Internal medicine and 7 subjects (23.3%) were neurology residents. All of them (100%) found the use of QR codes practical and easy. Analysis of data related to pre-test and post-test scores of residents shows that their average scores in the pre-test, 7 ±2.39, and their average scores in the test post 10.86 ±2.431, which indicates a significant increase after using the QR code poster (P-value = 0.000) Conclusion: The use of QR codes has been practical, easy, and user-friendly. Also, comparing the average scores of participants before and after the installation of these codes, shows that it has had a significant effect on training residents.
