Interventions, methods and outcome measures used in teaching evidence-based practice to healthcare students: an overview of systematic reviews.

BACKGROUND: To fully implement the internationally acknowledged requirements for teaching in evidence-based practice, and support the student's development of core competencies in evidence-based practice, educators at professional bachelor degree programs in healthcare need a systematic overview of evidence-based teaching and learning interventions. The purpose of this overview of systematic reviews was to summarize and synthesize the current evidence from systematic reviews on educational interventions being used by educators to teach evidence-based practice to professional bachelor-degree healthcare students and to identify the evidence-based practice-related learning outcomes used. METHODS: An overview of systematic reviews. Four databases (PubMed/Medline, CINAHL, ERIC and the Cochrane library) were searched from May 2013 to January 25th, 2024. Additional sources were checked for unpublished or ongoing systematic reviews. Eligibility criteria included systematic reviews of studies among undergraduate nursing, physiotherapist, occupational therapist, midwife, nutrition and health, and biomedical laboratory science students, evaluating educational interventions aimed at teaching evidence-based practice in classroom or clinical practice setting, or a combination. Two authors independently performed initial eligibility screening of title/abstracts. Four authors independently performed full-text screening and assessed the quality of selected systematic reviews using standardized instruments. Data was extracted and synthesized using a narrative approach. RESULTS: A total of 524 references were retrieved, and 6 systematic reviews (with a total of 39 primary studies) were included. Overlap between the systematic reviews was minimal. All the systematic reviews were of low methodological quality. Synthesis and analysis revealed a variety of teaching modalities and approaches. The outcomes were to some extent assessed in accordance with the Sicily group`s categories; "skills", "attitude" and "knowledge". Whereas "behaviors", "reaction to educational experience", "self-efficacy" and "benefits for the patient" were rarely used. CONCLUSIONS: Teaching evidence-based practice is widely used in undergraduate healthcare students and a variety of interventions are used and recognized. Not all categories of outcomes suggested by the Sicily group are used to evaluate outcomes of evidence-based practice teaching. There is a need for studies measuring the effect on outcomes in all the Sicily group categories, to enhance sustainability and transition of evidence-based practice competencies to the context of healthcare practice.

Teaching evidence-based practice to undergraduate healthcare students Educators' knowledge, skills, attitudes, current practice, perceived barriers, and facilitators: A Danish cross-sectional study.

BACKGROUND: Evidence-Based Practice is recognized as a standard practice and a core competence for clinical healthcare professionals and therefore educators' competences in teaching Evidence-Based Practice are essential. Yet only little is known about the knowledge, skills, attitudes, and teaching practices around Evidence-Based Practice among educators of Danish undergraduate healthcare students. OBJECTIVES: The objectives of this study were to describe: 1) the Evidence-Based Practice profiles regarding attitudes, knowledge, skills, and teaching practices among educators who teach in undergraduate healthcare educations; 2) the current state of teaching Evidence-Based Practice in undergraduate program curricula; 3) the perceived barriers and facilitators to teach Evidence-Based Practice; and 4) the educators` needs regarding teaching Evidence-Based Practice. DESIGN, SETTING AND PARTICIPANTS: A cross-sectional survey using a self-administrated online questionnaire among 81 educators at University College South Denmark. METHODS: The survey covered 1) Demographic questions, 2) Educators Evidence-Based Practice profiles measured by the Evidence-Based Practice Questionnaire for teachers, 3) perceived state of Evidence-Based Practice teaching 4) perceived barriers and facilitators and 5) educators´ needs for competence development regarding teaching Evidence-Based Practice. RESULTS: The translated version of the Evidence-Based Practice Questionnaire showed that respondents had a mean of 3,6 regarding practicing Evidence-Based Practice when asked to rank on a scale of 1-7 (higher score indicating higher degree). The respondents showed positive attitudes towards Evidence-Based Practice and had a high self-perception of their Evidence-Based Practice skills and knowledge, scoring an overall average value of 5 on these items. In open ended questions educators gave a variety of examples of their Evidence-Based Practice teaching in terms of content, teaching methods and cooperation with clinical practice. CONCLUSIONS: Educators report limitations to teaching Evidence-Based Practice; however, attitudes, knowledge and skills were perceived generally high. Main facilitator was partnership with clinical practice and main barrier was time lack. MESH: Evidence-Based Practice, Health Educators, Knowledge, Attitude.

Impact of a nationwide school policy on body mass index in Danish school children: An interrupted time series analysis.

Objectives: A new school policy mandating 45 min physical activity daily during school was introduced in Denmark in 2014. We aimed to evaluate the effect of this policy on BMI in school-aged children. It was hypothesized that the school policy would decrease BMI, especially in the obese fraction of the population (90th percentile BMI). Study design: This register-based study was conducted as a natural experiment. Methods: Analyses were based on data from The National Child Health Register that contains nationwide data on height and weight from mandatory preventive health examinations completed by school nurses or medical doctors during pre-preparatory classes (0th-3rd grade) and lower secondary education (7th-9th grade). A total of 401,517 children were included in the analyses with annual repeated cross-sectional data covering the period from 2012 to 2018. The effect of the school policy was evaluated using an interrupted time series approach comparing pre- and post-policy slopes in BMI, stratified by sex and age-group. Results: In boys, no significant differences were observed in mean BMI slopes from pre-to post-policy in either age-group. In girls, post-policy slopes were significantly higher compared to pre-policy in both age-groups (0th-3rd grade: ß:0·034 kg/m2, 95%-CI: (0·024; 0·043), p-value: <0·001; 7th-9th grade: ß:0·066 kg/m2, 95%-CI: (0·028; 0·103), p-value: 0·001). No significant differences in slopes were observed in BMI at the 90th percentile from pre-to post-policy for both sexes and across both age-groups. Adjustment for leisure-time physical activity as a potential time-varying confounder did not alter the findings. Conclusions: In conclusion, we did not detect a significant decrease in BMI levels among school-aged children following the introduction of a nationwide school policy specifying daily physical activity in school. If anything, a small positive change in BMI was observed in girls. More research is needed to understand whether structural changes similar to this requirement are able to prevent overweight and obesity in children and adolescents.
