title: Evidence based medicine: an overview.
abstract: Evidence based medicine (EBM) considered one of the most important developments in the practice of medicine in recent years, has evolved as a tool for improving the quality of health care. Several studies have shown EBM to be safe and cost-effective. Physicians have welcomed EBM and shown a positive attitude toward it and have expressed desire to learn more about it. This is consistent in most studies done in different countries. However, some studies found considerable misunderstanding about terms and websites used in EBM. The major barriers to the practice of EBM perceived by physician in different studies include insufficient time and evidence, patients' preference and financial constraints. Training has been found to be conducive to the implementation and promotion of EBM. Some Arab countries are already implementing EBM and plan to include it in the undergraduate curriculum. In Saudi Arabia EBM was introduced in the late 90's and a National EBM Advisory Board was formed.
