RESUMEN
Objective Emergency Medicine (EM) Sim Cases was initially developed in 2015 as a free open-access simulation resource. To ensure the future of EM Sim Cases remains relevant and up to date, we performed a needs assessment to better define our audience and facilitate long-term goals. Methods We delivered a survey using a modified massive-online-needs-assessment methodology through an iterative process with simulation experts from the EM Simulation Educators Research Collaborative. We distributed the survey via email and Twitter and analyzed the data using descriptive statistics and thematic analysis. Results We obtained 106 responses. EM Sim Cases is commonly used by physicians primarily as an educational resource for postgraduate level trainees. Perceived needs included resuscitation, pediatrics, trauma, and toxicology content. Prompted needs included non-simulation-case educational resources, increased case database, and improved website organization. Conclusions Data collected from our needs assessment has defined our audience allowing us to design our long-term goals and strategies.
