Introduction: In recent years, the number of people with mild traumatic brain injury (TBI) evaluated in emergency departments has grown. Although research efforts have attempted to identify best practice recommendations for mild TBI management, transfer of these into clinical practice remains an obstacle in many settings with limited access to the relevant information/knowledge for a variety of reasons.  It is therefore essential to determine an effective means for emergency staff to access information about mild TBI and apply best care practices for the benefit of these patients.  The goal of this project was to identify the needs and expectations of emergency staff regarding training in mild TBI management. Methodology: A cross-sectional web-based study was conducted using a self-report online survey that targeted all doctors and nurses from three emergency rooms in the province of Quebec, Canada. The medical coordinators of these sites were contacted and transferred by email the electronic survey link to all doctors and nurses of their respective site. Practitioners (doctors and nurses) completed this electronic survey sent one time between January and March 2017. Its purpose was for clinicians to identify the best means of knowledge transfer for mild TBI management that would be easily applicable to the current context of emergency department reality. Following this survey, interviews were conducted in these three settings to clarify the parameters of the tool to be developed. Results: A total of 150 clinicians answered to the survey (72.4% nurses, 25% doctors, 2.6% students) and 8 participants were interviewed (6 doctors and 2 nurses). Most of the participants (47.5%) wanted a mobile application on mild TBI as an educational tool that would be available at all times (20%). A total of 32.8% of participants mentioned that they would estimate having less than 5 minutes to consult such an application. After the first assessment to consult such an application, a total of 38.3% of the participants reported they would review the app after the first assessment of the same patient and 36.2% report that they would review the app after the assessment. A total of 74.8% report that they will use this app via a smart phone. They indicated that the application should contain information on appropriate recommendations for emergency care (68.3%), diagnostic criteria (67.2%), assessment tools (59.6%), decision-making algorithms (59.2%), and poor prognostic factors (57.4%). Conclusion: The results of the present survey and individual interviews will guide the development of a mobile application to support emergency clinicians addressing the needs identified in the survey and further clarified in the individual interviews.  Information quickly available on a smart phone including diagnostic criteria, assessment tools, decision making algorithms, prognostic factors and recommendations should be included in a mobile application on mild TBI.
