Brain Death Knowledge and Attitudes Among Fourth-Year Medical Students at Umm Al-Qura University.

Background Despite clear definitions of brain death, students and medical professionals may have varying understandings. This study investigated the knowledge and attitudes of medical students regarding brain death. Methods A cross-sectional survey was administered to 142 fourth-year medical students at Umm Al-Qura University. The survey used single-choice and Likert scale questions to assess knowledge of brain death definition, diagnosis procedures, and student attitudes. Prior to administration, the questionnaire underwent content validation by experts in medicine, ethics, and public health. Results A significant proportion of students lacked knowledge of the legal definition of brain death in Saudi Arabia (26.1%), brain death diagnostic procedures (43.7%), and prerequisites for declaring brain death (38%). While some students expressed confidence in diagnosing brain death, concerns about misdiagnosis were also present. Conclusion Fourth-year medical students in this study demonstrated significant knowledge gaps regarding brain death. Medical education programs may need to be revised to provide more comprehensive training on brain death and its implications. Additionally, public awareness campaigns could improve understanding and facilitate informed decision-making about organ donation. Further research, including multicenter studies, is warranted to confirm these findings and guide educational interventions.
