To investigate the relation between knowledge of universal precautions and rates of exposure to blood and body fluid during clinical training, a cohort of 155 students was surveyed following training in universal precautions and 18 months later. A total of 127 students (82%) participated; 58 (46%) experienced at least one exposure during the first clinical training year. Knowledge of universal precautions was inversely associated with the frequency of mucous membrane exposures (p .001); an apparent "dose-response" effect was evident (one-way analysis of variance; F = 5.2, p - 0.007). Students are frequently exposed to blood and body fluid during clinical training. Higher levels of retained knowledge about universal precautions are associated with a decreased risk of mucous membrane exposure.
为了研究临床培训期间普遍预防措施的知识与血液和体液暴露率之间的关系，对155名学生进行了队列研究，在他们接受普遍预防措施培训后以及18个月后进行了调查。共有127名学生（82%）参与；58名（46%）在第一个临床培训年期间至少经历了一次暴露。普遍预防措施的知识与黏膜暴露频率呈负相关（p<0.001）；明显的“剂量反应”效应显著（单因素方差分析；F = 5.2，p = 0.007）。学生在临床培训期间经常接触血液和体液。对普遍预防措施保留的知识水平较高与黏膜暴露风险降低相关。
