The aim of this study was to assess the knowledge of medical (MS) and nursing (NS) students about prevention of the HCAIs and to detect differences between these two groups. It was the pilot study of a national investigation and was performed administering a questionnaire including 6 multiple choice questions concerning 3 areas: standard precautions (SP), hand hygiene (HH) and nosocomial infections (NI). One hundred and seventeen students, 89 MS and 28 NS, were included in the study. Mean overall score (+/- SD) was 17.63 (+/- 3.8), on an overall perfect score achievable of 25. Mean score obtained by NS (18.5 +/- 3.3) was better than the one achieved by MS (17.4 +/- 3.9), even if the difference wasn't statistically significant. Stratifying the score in the three specific areas, healthcare students obtained weighed scores (+/- SD) of 6.74 (+/- 1.61) for SP, 4.7 (+/- 1.5) for HH and 4.51 (+/- 1.71) for NI. Knowledge level concerning HH area was different between medical students and nursing students (p = 0.013), in favour of the latter. According to correct answers rate, healthcare students properly know how and what kind of personal medical devices are to be used, while they show a lack of knowledge about hand hygiene. This pilot-study underlines the importance of the assessment of teaching effectiveness, and it stresses the need to critically review some specific contents of healthcare university courses.
本研究旨在评估医学专业（MS）和护理专业（NS）学生对医院感染预防的知识，并检测这两组学生之间的差异。这是一项全国性调查的试点研究，通过发放一份包含6个多项选择题的问卷进行，这些问题涉及3个领域：标准预防措施（SP）、手卫生（HH）和医院感染（NI）。117名学生参与了该研究，其中89名医学专业学生和28名护理专业学生。在满分可达25分的情况下，平均总分（±标准差）为17.63（±3.8）。护理专业学生获得的平均分数（18.5±3.3）高于医学专业学生（17.4±3.9），尽管差异无统计学意义。将分数按三个特定领域分层，医学生在标准预防措施方面的加权分数（±标准差）为6.74（±1.61），在手卫生方面为4.7（±1.5），在医院感染方面为4.51（±1.71）。医学生和护理专业学生在手卫生领域的知识水平存在差异（p = 0.013），护理专业学生更具优势。根据正确答案率，医学生正确了解如何以及使用何种个人医疗设备，但他们在手卫生方面知识欠缺。这项试点研究强调了评估教学效果的重要性，并强调有必要批判性地审查医科大学课程的一些特定内容。
