医学生对实验室生物安全认知情况调查

目的了解某医学院学生对实验室生物安全的认知现状,为我国高校实验室生物安全管理工作提供基本资料。方法采用整群随机抽样的方法抽取900名全日制在校本科二、三年级医学生,以自填方式进行问卷调查。结果发放调查问卷900份,获得有效问卷877份,有效率为98.21%,其中二年级430名(49.03%),三年级447名(50.97%),148名(16.88%)学生曾参与大学生科研。实验室生物安全概念的总体知晓率为58.72%,了解实验室生物安全法规具体内容的仅占32.16%,仅8.21%的学生接受过实验室生物安全培训;对实验室生物安全柜的知晓率仅为14.14%,仅7.75%的学生清楚哪些操作需要在生物安全柜中进行;28.28%的学生能按照规定处理废弃物,68.19%的学生能识别生物危害警示标志;92.82%的学生认为应开设实验室生物安全相关课程。实验室生物安全知识和安全行为总体知晓率偏低,分别为42.65%和41.96%,且三年级知晓率高于二年级(P0.05);化学性危害和生物性危害方面:有过科研经历的学生得分高于未参加过大学生科研的学生(均P0.05)。结论医学生对实验室生物安全知识的认知情况不容乐观,应切实加强实验室生物安全教育管理和宣传工作,提高学生的实验室生物安全认知水平。

Medical students’ cognition on laboratory biosafety

ObjectiveTo investigate cognitive status of medical students of a medical university on laboratory biosafety, and provide basic data for laboratory biosafety management in Chinese universities.Methods900 full time undergraduate medical students were chosen by cluster random sampling, questionnaires were filled out in by them.Results900 questionnaires were distributed, 877 (98.21%) valid questionnaires were obtained, 49.03% (n=430) were from sophomores, 50.97%（n=447）from juniors，148（16.88%）students have ever participated in students’ scientific research. The overall awareness rate of laboratory biosafety was 58.72%, only 32.16% of students understood the detailed contents of laboratory biosafety regulations, only 8.21% of students have received training in laboratory biosafety; the awareness rate of laboratory biosafety cabinet was only 14.14%, only 7.75% of students knew which operation should be performed in biosafety cabinet; 28.28% of students could deal with waste according to the rules, 68.19% of students were able to identify warning signs of biological hazard; 92.82% of the students thought that laboratory biosafety related courses should be set up. The overall awareness rate of laboratory biosafety knowledge and safety behavior was low, which were 42.65% and 41.96% respectively, juniors was higher than that of sophomores(P<0.05); in the aspect of chemical hazards and biological hazards, students with scientific research experience scored higher than those who did not participate in scientific research(all P<0.05).ConclusionMedical students’ cognition on knowledge of laboratory biosafety is not optimistic, it is imperative to strengthen the management of education and publicity of laboratory biosafety.
