Cell phones are one of the most important and indispensable accessories for professional and social life. Cell phones used by healthcare workers are highly contaminated by microorganisms. The objective of the study was to ascertain the presence of bacterial resistance type Extended-Spectrum Beta-Lactamase [ESBL] and its related factors in cultures isolated from cell phones of medical students. A quantitative, observational, analytical and transversal study was carried out in students of the Faculty of Medicine of the Universidad Nacional Hermilio Valdizán in Huánuco, Peru. The relationship was sought between the frequency of attendance at hospital practices, cell phone disinfection and hand washing after contact with patients with the presence of ESBL-type bacterial resistance. Of the total sample, 95% of students presented positive culture to Gram-negative bacteria, 30% carried out the disinfection of their cell phone and only 5% of the students performed hand-washing in an appropriate manner. In the bivariate analysis, a statistical association was found between cell phone disinfection and the presence of ESBL-type bacterial resistance [p <0.05]. Cell phone disinfection is related to the reduction of ESBL-type resistance, highlighting the need for disinfection of cell phones after performing hospital practices.
手机是职业和社交生活中最重要且不可或缺的配件之一。医护人员使用的手机被微生物高度污染。本研究的目的是确定从医学生手机分离的培养物中是否存在超广谱β-内酰胺酶（ESBL）型细菌耐药性及其相关因素。在秘鲁瓦努科的国立埃尔米利奥·瓦尔迪赞大学医学院的学生中开展了一项定量、观察性、分析性和横断面研究。研究了医院实习出勤频率、手机消毒以及接触患者后洗手与ESBL型细菌耐药性存在之间的关系。在总样本中，95%的学生革兰氏阴性菌培养呈阳性，30%的学生对其手机进行了消毒，只有5%的学生正确洗手。在双变量分析中，发现手机消毒与ESBL型细菌耐药性的存在之间存在统计学关联（p<0.05）。手机消毒与ESBL型耐药性的降低有关，突出了医院实习后对手机进行消毒的必要性。
