This thesis argues about the possible epidemiologic study designs and strategies of data analysis capable of attaching the interest ocurrence functions in the factories of risks studies for inadequate medical prescriptions, for children with acute respiratory infection, that are taken care of in the ambulatory services. In order to reach this, the main theoretical marks which should limit the construction of a epidemiologic study design are shown, as well as the different stages that should be considered when someone is planning a process of statistics analysis in epidemiologic studies. From the elaboration of a theoretical-conceptual model that represents the relationships between the several factors which seem to be involved with the prescription and use of medicines, different strategies of research and analysis plans are discussed, being watchful for the main problems to be avoided when someone looks for a study with a satisfatory validity and precision.
