Aim: Allow online training, evaluation and feedback of Obstetrics students in emergency care: obstetric haemorrhage (red key). Methods: an analysis of the current state of the teaching of emergency obstetric haemorrhage was performed, the basic requirements, functionalities and deliverables were based in the SCRUM methodology. A web server, a “Somee” database management system, SqlServer and Visual Studio application development environment were required. The database model was designed based on the emergency learning requirements identifying all the entities, standardization techniques of the tables originated from the entities were applied; the user interfaces were designed. Conclusion: The GEO web application provided the feedback of knowledge to the Obstetrics student after its use and evidenced in the results an improvement in the qualification (p <0.05). The use complements the teaching that is currently practiced in the classrooms, promoting the improvement of the quality of teaching through the integration of a new self-learning model.
