Background: Mobile learning refers to the use of mobile or wireless devices for learning purposes while on the move. It is a learning technique that can be applied in multiple contexts through social and content interactions. “Mobile” learners can use it as an educational technology in a variety of settings available at their convenience.In medicine, new technology offers the potential to enhance learning and patient care, although it also poses potential risks, such as superficial learning, failure to understand how to discriminate reliable sources of information, distraction, inappropriate use, and privacy-related issues. The aim of this study is to assess the usefulness of mobile devices for residents in the clinical settings of a hospital.Methods: Mixed method design on pediatric surgery residents. Quantitative data were analyzed via a simple discriminant analysis. Qualitative data were obtained using the focus group technique, with a subsequent triangulation of data.Results: All residents use devices for learning and communication. The triangulation analysis yielded the following categories: agile communication, search for data on drugs and prognosis, consultation of medical applications, limitations of devices, and inconsistencies between the official regulations and their advantages in clinical practice.Conclusions: We demonstrate the usefulness of mobile devices among surgical residents within the clinical care. Every hospital should regulate its policies for better use of devices.
