Medical students who engage in clinical learning in healthcare settings can be potential methicillin-resistant (MRSA) carriers.
This is a descriptive cross-sectional study having a follow-up approach. Three batches of medical students who were studying at the Faculty of Medicine and Allied Sciences, Rajarata University of Sri Lanka (1, 3 and 5 study years of MBBS course) were screened for nasal and axillary MRSA colonization. The first-year students were screened before and 6 months after clinical learning. The knowledge of the students about infection control was scored (percentage) using a questionnaire in the one week before and later one year after the hospital exposure. Data was compared using two-sample t test.
The percentage of MRSA colonization was 6.36% (7/110) and 49.57% (59/119) before clinical exposure and after 2.5 years of exposure, respectively (p<0.012). The percentage of correct responses obtained by the students for the questionnaire about infection control was 28% and 66.9% one week before the exposure to the hospitals and one year after the exposure to the hospitals, consecutively.
MRSA carriage was significantly associated with the time duration of the clinical training of the medical students. The knowledge of students about infection control was significantly inadequate one week before the hospital exposure and they have gained the knowledge only after being exposed to the hospitals.
在医疗机构中进行临床学习的医学生可能是耐甲氧西林金黄色葡萄球菌（MRSA）的潜在携带者。
这是一项采用随访方法的描述性横断面研究。对斯里兰卡拉贾勒塔大学医学与联合科学学院的三批医学生（医学学士课程的第1、3和5学年）进行了鼻腔和腋窝MRSA定植筛查。一年级学生在临床学习前和学习6个月后进行了筛查。在医院接触前一周和接触一年后，使用问卷对学生的感染控制知识进行评分（百分比）。数据采用两样本t检验进行比较。
临床接触前和接触2.5年后，MRSA定植的百分比分别为6.36%（7/110）和49.57%（59/119）（p<0.012）。学生在接触医院前一周和接触医院一年后，关于感染控制问卷的正确回答百分比分别为28%和66.9%。
MRSA携带与医学生临床培训的时长显著相关。学生在接触医院前一周关于感染控制的知识明显不足，他们仅在接触医院后才获得了相关知识。
