Introduction: evidence-based medicine is a natural response to the need of creating a healthcare model that allows the integration of the results of the advances in clinical research into daily practice. Objectives: To characterize the use of evidence-based medicine in the act of prescribing. Methods: We conducted a cross sectional study in the first level of care. We included, at random, 9 provinces (Santiago de Cuba, Havana, Matanzas, Pinar del Rio, Camagüey, Ciego de Avila, Holguín, Granma and Guantanamo) that constitute 60 % and of these, 25 % of the clinics (82). The selection of these was by simple random sampling with the statistical program EPIDAT. 765 prescribers were included since they were serving in the selected areas at the time of the application of this instrument. For the collection of information a questionnaire "Prescribing scientific evidence" was designed in order to capture all the information on the variables defined. Results: Over half of respondents (442) noted that often feel the need to seek information, this necessity increases when less time professional experience, although the frequency of seeking for more information is annually low, with an average of 6, 48 times a year and a mode of zero. Concerning prescriptions, the respondents reported having more questions (69.4 %) about drug interactions. Conclusions: Half of the respondents stated that they often feel a need for review of scientific literature to answer questions during the act of prescribing. However, the sources they use are printed and updating courses. Interactions and adverse reactions are the aspects that they usually seek about, but they refer they often take into account the availability of the drug at the time of prescribing.
