Abstract

Introduction: The Ultimate Bedside Compatibility Test (UBT) is a key safety step to prevent ABO- compatibility transfusion errors. Mandatory inTunisia since 2005,it is performed under the responsibility of the prescribing physician. As traditional teaching methods often prove insufficient for developing practical skills, video capsules are being explored as innovative tools to enhance medical students learning on transfusion safety.
 Objective:to evaluate the educational impact of teaching using a video capsule on the UBT performance acquisition by medical students.
Methods: We conducted a prospective study during the 2023–2024 academic year among third-year medical students who completed a hematology rotation at Aziza Othmana Hospital, Tunis. Students were evaluated before and after viewing a 5-minute instructional video
detailing the UBT procedure. Performance was assessed using a standardized check list and analyzed with SPSS software.
Results: Seventy students were included,with a female predominance (75.7%). Before the teaching session using the videocapsule, the mean score was 8.83/20 and the correct response rate was 40%. After the intervention, the mean score was 17/20(p<0.001),with a correct response
rate of 83.8% (p=0.04).The average improvement was 43.8%. Potentially dangerous responses decreased from 24% to 5.7% (p=0.005).
Conclusion: The video capsule effectively improved medical students’ knowledge and performance on the UBT, significantly reducing potentially serious errors and enhancing transfusion safety. It represents a valuable and convinient tool for medical education
