Aim: Allow online training, evaluation and feedback of Obstetrics students in emergency care: obstetric haemorrhage (red key). Material and methods: an analysis of the current state of the teaching of emergency obstetric haemorrhage was performed in students of the VIII Semester of the Faculty of Obstetrics and Childcare of the Universidad Católica de Santa María, 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; necessary information was collected for the records in the tables; The user interfaces were designed, a first level identification page was developed that controls access to the system and differentiation of functions according to the type of user, followed by a search tool that provides the user with a list of obstetric emergencies with keywords. Finally, an evaluation module was developed to analyze student performance. To provide the functionality required to the application, a set of routines were developed that included querying and updating at runtime the information shown in the interface, consulting and downloading external files in PDF format. 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 of the GEO Web application as developed information technology, 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.
