Knowledge, attitude, and barriers towards the use of evidence based practice among senior dental and medical students in western Saudi Arabia.

Objectives: To investigate the knowledge, attitude, and barriers using evidence based practice (EBP) by future Saudi dentists and physicians.

Methods: A questionnaire adapted from an EBP questionnaire was distributed to dental and medical final year students and new graduates at King Abdulaziz University, Jeddah, Saudi Arabia during the 2012 to 2013 academic year. The questionnaire consisted of 14 multiple-choice questions, and 2 open ended questions and was divided into 5 sections assessing different categories. Data were grouped as dental (DS) and medical (MS) students. Descriptive and group comparison statistics were conducted.

Results: Out of 400, 297 students responded (DS=207, MS=90) with a 74% response rate. The students' knowledge and attitude were low with no significant difference between the 2 groups. Students` knowledge and attitudes towards EBP were assessed: EBP course attendance (DS=40.1%, MS=13.3%; p=0.000), reading journals (DS=6.3%, MS=3.3%; p=0.313), awareness of EBP components (DS=7.7%, MS=0%; p=0.332), and awareness towards the strongest evidence for EBP (DS=58.9%, MS=53.3%; p=0.370). More than half of the students in both groups did not use EBP in their treatment (DS=85%, MS=84.4%; p=0.842). The greatest reported barriers were;  EBP is difficult to understand (DS=88.9%, MS=72.2%; p=0.000), and no time (DS=54.6%, MS=46.7%; p=0.210).

Conclusion: The reported knowledge and attitudes among the junior health care physicians is considered below the required competency standards. These findings highlight the urgent need for changes in the current educational strategies to assure successful implementation of EBP in Saudi Arabia.
