Sleep disorders affect millions of Americans and are directly associated with many deadly diseases, including neurological disorders. Despite this impact, sleep medicine education is not included in many U.S.-based neurology residency education programs, resulting in under-diagnosed patients and missed therapeutic opportunities. This study aims to examine a possible solution to this gap by integrating a supplemental sleep education program that residents can complete via e-learning on mobile devices. The research goal is examining the educational experience of neurology residents as they participate in a supplemental sleep medicine e-learning module. This research included a case study of nine neurology residents involved in various years of residency training at the University of North Carolina at Chapel Hill's School of Medicine. Participants utilized an e-learning module with a streaming video lecture series, online discussion board, and authentic sleep medicine resources. Major findings include the following: pedagogical issues of the online module with regard to specific e-learning constructs include practical, authentic, and contextual information and teaching tools, facilitator scaffolding has a positive influence, module design should allow self-direction and mobile learning is preferred, and supplemental discussion forums may be useful; strengths of the module include flexibility, use of multimedia, practicality, and ease of use; areas for improvement of the module include timing of the module, content length and context, and addition of prompting and reminders; the usefulness, application, and takeaways from the module include that residents prefer mobile e-learning, will potentially use the module for foundational knowledge, for reinforcement, and potentially for patient care during and beyond residency. Four themes emerged in the discussion, which include: Module timing and delivery presented the biggest issues, self-control of learning and non-linear design were large indicators of satisfaction, introverted nature of the participants governed their participation, and context is important and varies according to where residents are in their education. Overall, the findings of this research support the idea that supplemental education on sleep disorders completed through electronic learning (e-learning) and mobile learning (m-learning or mlearning) platforms provides a portable and acceptable solution for neurology residents to gain critical knowledge and skills in sleep medicine. The use of e-learning and m-learning in medical residency education are promising methods for understanding how residents experience online supplemental sleep medicine education; as well as promising for understanding the overall feasibility, educational impact, and applicability of the module itself.
