There have existed for a long period several strategies developed by international organisms to improve their intervention at the very rst level of some public health problems. In particular, the prenatal control has been introduced as a structured strategy for the rst level as the integrated management of childhood illness (AIEPI in spanish) since more than twenty years. This paper presents a novel approach to include recent technological advances within the work ow of such process so that it facilitates interaction and decreases the training time. The method, named herein TeleAIEPI, implements the whole AIEPI questionnaire in a mobile application with high portability, little computational requirements and usability. The success of teleAIEPI application is completely dependent on the usability and integrability with any mobile device. The architecture, functional requirements and usability evaluation are herein presented, showing an adequate performance when real users interact with such an application.
