Online bibliographic databases constitute the access to information supporting evidence-based practice. The purpose of the present survey is to evaluate the awareness, the use and the impact that online evidences have in clinical practice. An online survey was conducted using a 25 item questionnaire which was completed by 263 healthcare practitioners (nurses and doctors). Chi-square analysis and t-tests were used and comparisons between both groups were made. Multiple logistic regression to predict databases use was employed. Ninety-three percent (n = 206) of participants had heard about the online bibliographic databases; 5.7% of participant sample have heard about online databases but they do not use them. 18.3% was the total sample of non-users (n = 48). The main reason of using was filling a knowledge gap (50.7%), and the main reasons of not using were both that they use another information source and they don't need them to do their job. Both nurses and doctors believe that the use of online databases improves patient care it is a part of their legitimate clinical role. They need more training to improve their searching skills, enhancing them in everyday clinical place.
