受污染的手机是导致医院获得性感染（HAI）的生物体的宿主。医学生对手机使用感染预防和控制（IPC）的意识了解甚少。我们展示了马凯雷雷大学健康科学学院最后一年级医科学生的手机上存在的微生物，并评估了他们在医院环境中对手机卫生和使用IPC的认识。本横断面研究采用标准生化试验和全自动BD Phoenix仪器对79名医学生手机拭子进行微生物鉴定和药敏试验。数据收集使用自我管理问卷来评估学生的意识。采用STATA软件16版进行分析。70部（88.6%）手机被至少一种微生物污染。检出细菌148株，其中革兰氏阳性123株（83.1%），革兰氏阴性24株（16.2%），酵母菌1株（0.7%）。凝固酶阴性葡萄球菌是革兰氏阳性菌中最常见的。革兰氏阴性菌中最常分离出鲍曼不动杆菌。关于手机卫生的IPC平均实际得分（34%）显著低于IPC平均意识得分（77%）（p≤0.0001）。74名（93.7%）学生在各个病房轮流使用手机。40名（50.6%）学生在病房轮岗后用含酒精的洗手液清洗手机。35名（44.3%）学生了解他们轮岗的医院的IPC项目。医学生手机细菌污染发生率高。与轮换病房相比，学生在手机卫生方面的IPC实践得分低于IPC意识得分。最后一年的医学学生的课程应该包括与ipcc相关的主题，其中包括实用技能。
Contaminated mobile phones act as reservoirs for organisms causing hospital-acquired infections (HAI). Little is known about medical school students’ awareness of infection prevention and control (IPC) regarding mobile phone use among medical students. We demonstrated the presence of organisms on mobile phones of final-year medical students at Makerere University College of Health Sciences and evaluated their awareness of IPC regarding mobile phone hygiene and use in a hospital setting. In this cross-sectional study, organisms from swabs obtained from 79 medical students’ mobile phones were identified and antimicrobial susceptibility test carried out using standard biochemical tests and the automated BD Phoenix instrument. Data were collected using a self-administered questionnaire to assess the students’ awareness. The analysis was carried out using STATA software version 16. Seventy (88.6%) mobile phones were contaminated with at least one organism. One hundred forty-eight bacteria were isolated, of which 123 (83.1%) were Gram-positive, 24 (16.2%) were Gram-negative, and 1 (0.7%) was yeast (Candida spp). Coagulase negative staphylococci were the most frequently isolated among Gram-positive bacteria. Acinetobacter baumannii were the most frequently isolated among Gram-negative bacteria. The average IPC practical score regarding mobile phone hygiene (34%) was significantly lower than the average IPC awareness score (77%) (p ≤ 0.0001). Seventy-four (93.7%) students use their phones while rotating in the various wards. Forty (50.6%) of the students cleaned their phones with alcohol-based sanitizer after rotations in the ward. Thirty-five (44.3%) students were aware of IPC programs in the hospital they rotated in. There is a high prevalence of bacterial contamination from mobile phones of medical students. The students had lower IPC practical scores compared to IPC awareness scores regarding mobile phone hygiene irrespective of the ward of rotation. Curriculum of final-year medical students should include IPC-related topics, which incorporate practical skills.
