Evidence-based practice among health students: attitudes, knowledge, skills and perceived barriers

Abstract Introduction Evidence-based practice (EBP) is a worldwide approach in optimizing quality of healthcare. As healthcare providers are increasingly more involved in clinical decision making, it is becoming important for them to use the best evidence to make effective and justifiable decisions. EBP is an important competency of undergraduate healthcare students that remains little known among Tunisian future healthcare professionals. This study aimed to describe health sciences students' attitudes. Knowledge and skills in EBP; to determine factors associated with these competencies and to identify perceived barriers regarding EBP. Materials and Methods A descriptive cross-sectional study was conducted at the Higher School of Health Sciences and Techniques of Sousse among 365 health sciences students enrolled during the second semester of the academic year 2017-2018. Data was collected using a self administrated questionnaire including a validated EBP-COQ questionnaire and focusing on identifying the perceived barriers to the usage of EBP. Results The response rate was 93.11%. Approximately, 61.6% of students were familiar with the term ‘EBP'. The overall score of EBP-COQ questionnaire was 3.26 ±0.53 out of 5. The mean scores of attitude, skills and knowledge subscales were 4.04 ±0.41; 3.05 ±0.77 and 2.70 ±0.74 respectively. A significant statistical association was found between the competencies in EBP and age; gender, academic degree, year of study for license degree, students' English-language reading skills, students' education in research methodology and statistics (p < 10-3). The top reported barriers hindering their adoption of EBP were: lack of training in EBP, difficulty in obtaining full-text papers and lack of time. Conclusions The strategic position of healthcare students may influence the adoption of EBP. It is necessary to understand students' attitudes, knowledge and skills in the subject to be able to develop effective strategies for EBP curricula. Key messages Evidence-based practice is a worldwide approach in optimizing quality of healthcare. It is necessary to understand students' attitudes, knowledge and skills to develop effective learning strategies.
