Evidence based medicine is the complex, conscientious, explicit, and judicious use of current best evidence in making medical decisions about the care of individual patients there has been a general consensus that continuous, comprehensive practice of evidence based medicines has tremendous potential to improve the quality of care. It is not based only on the available evidence but also on patient characteristics, situations, and preferences. It recognizes that care is individualized and ever changing and involves uncertainties and probabilities. Computerized clinical decision support system (CDSSs) are information systems designed to improve clinical decision making. Clinical decision support system have shown to improve the quality of care. Evidence based medicine has shown that computerized clinical decision support systems can improve physicians guideline compliance and thus patient health. In this work, I have implemented evidence based medicine principles via a CDSS, defined as a computer software using a knowledge base designed for use by a clinical involved in patient care as a direct aid to clinical decision making. The decision support system provides suggested actions for physicians and established treatment protocol. Such a reminder system may enable physicians to make better quality decisions, and may enable patients more consistently follow the medical recommendations. The purpose of this work is to implement a computer based guideline driven multiple screening program in an outpatient setting as well as to evaluate its impact on facilitating preventive care in terms of expected life saving. A protocol DSS known as Clinical Reminder System is presented, that combines a relational database, a knowledge base consisting of algorithms that implement disease treatment protocols, integration with hospital legacy systems and allows physicians to manage the patient data and suggest medical responses. This program provides physicians with preventive service reminders and gave patients health care education, direct access to health consultations and preventive tools so that all the required features of CDSS mentioned above were complied with.
