Knowledge and attitude toward evidence-based medicine among medical students in Semnan, Iran

The effect of capacity building evidence-based medicine training on its implementation among healthcare professionals in Southwest Ethiopia: a controlled quasi-experimental outcome evaluation

BACKGROUND

Evidence-based medicine (EBM) bridges research and clinical practice to enhance medical knowledge and improve patient care. However, clinical decisions in many African countries don't base on the best available scientific evidence. Hence, this study aimed to determine the effect of training interventions on background knowledge and awareness of EBM sources, attitude, competence, and practice of EBM among healthcare professionals.

METHOD

We designed a controlled group quasi-experimental pre-post test study to evaluate the effect of capacity-building EBM training. A total of 192 healthcare professionals were recruited in the study (96 from the intervention and 96 from the control group). We used a difference-in-differences (DID) analysis to determine the effect of the training. Along the way, we used a fixed effect panel-data regression model to assess variables that could affect healthcare professionals' practice of EBM. The cut point to determine the significant effect of EBM training on healthcare professionals' background knowledge and awareness of EBM sources, attitude, and competence was at a P-value < 0.05.

RESULT

The DID estimator showed a significant net change of 8.0%, 17.1%, and 11.4% at P < 0.01 on attitude, competence, and practice of EBM, respectively, whereas no significant increment in the background knowledge and awareness of EBM sources. The fixed effect regression model showed that the attitude [OR = 2.288, 95% CI: (1.049, 4.989)], competence [OR = 4.174, 95% CI: 1.984, 8.780)], technical support [OR = 2.222, 95% CI: (1.043, 3.401)], and internet access [OR = 1.984, 95% CI: (1.073, 4.048)] were significantly affected EBM practice.

CONCLUSION

The capacity-building training improved attitude, competence, and EBM practice. Policymakers, government, and other concerned bodies recommended focusing on a well-designed training strategy to enhance the attitude, competence, and practice towards EBM among healthcare professionals. It was also recommended to enhance internet access and set mechanisms to provide technical support at health facilities.

Evidence-based medicine (EBM) for undergraduate medical students in Sudan: sources of information, knowledge about terms, skills related to EBM and attitude toward EBM in Sudan

BACKGROUND

Evidence-based medicine (EBM) is the use of the current best evidence for patient care. Medical students should critically appraise the research evidence to help them during their clinical practice in the future. We conducted this study to assess the skills, terms and attitude toward EBM.

METHOD

We conducted a cross-sectional study for medical students from governmental universities. Students completed an online validated questionnaire consisting of several sections to assess skills, attitude and knowledge about terms related to EBM. We used a scale ranging from 1(strongly disagree) to 5(strongly agree) for the 11 questions assessing the attitude and a scale ranging from 1(Poor) to 5(advanced) for EBM skills.

RESULTS

A total of 761 medical students with a mean age of 21.97 ± 1.64 participated in the study. 327 (43 %) of them were males. The most commonly used search engines were Google 690 (91 %) and Wikipedia 465 (61 %). Medical books 719 (94 %) and lecture notes 353 (46 %) were the most common sources for health information. The majority of students rated their skills related to EBM as average and below average for all questions (overall = 2.18 ± 0.8). Students rated their skills as poor (31 %) in locating professional literature, as average (34 %) in searching online databases, poor (42 %) in critical appraisal of a scientific publication reporting findings from clinical research and poor (36 %) in Critical appraisal of available scientific literature. Regarding attitude, the overall mean score was 2.83 ± 0.76. There is no significant difference in attitude score between students with or without EBM training (P = 0.2). The terms with the highest understanding were case-control study (45 %) and case report (44 %) for study design. Median (44 %) and sample size (43 %) for statistics. Incidence (46 %) and prevalence (44 %) for epidemiology.

CONCLUSIONS

Medical students have a knowledge gap in skills and terms related to EBM and an average attitude towards EBM. The majority of them were using a nonscientific search engine to obtain medical information. There is a need to educate students about the proper steps for getting the scientific literature and EBM skills.

Factors Associated with Practicing Evidence-Based Medicine Among Medical Interns in Amhara Regional State Teaching Hospitals, Northwest Ethiopia: A Cross-Sectional Study

BACKGROUND

Evidence-based medicine (EBM) is an important component of modern medicine and is essential for the provision of high-quality health services. Little is known about the level of EBM use among Ethiopian medical students. This study aimed to assess the factors associated with EBM practice among medical interns in teaching hospitals in northwestern Ethiopia.

METHODS

A cross-sectional study was conducted using a random sample of medical interns in teaching hospitals of northwest Ethiopia. Binary logistic regression analysis was used to identify factors associated with EBM practice. The strength of the interaction between variables was calculated using the adjusted odds ratio (AOR) with a 95% confidence interval (CI).

RESULTS

Completed questionnaire was obtained from 403 (95.3%) of 423 medical interns. About 48.4% of respondents had a good EBM practice. EBM knowledge (AOR = 1.86, 95% CI = 1.220-2.835), attitude to EBM (AOR = 2.05, 95% CI = 1.318-3.193), ability to appraise evidence (AOR = 2.35, 95% CI = 1.570-3.517), and having sufficient time to search for evidence (AOR = 1.67, 95% CI = 1.065-2.627) were factors significantly associated to EBM practice.

CONCLUSION

This study demonstrates that the main factors affecting medical intern's practice of EBM were lack of critical appraisal skill, lack of knowledge needed to practice EBM, negative attitudes toward EBM, and insufficient time to search for evidence. Providing EBM training to the needs of medical interns would overcome the barriers identified in this study, as well as assist medical interns and other clinical staffs to ensure the correct application of EBM in to clinical practice.

Knowledge and Attitude Toward Evidence-Based Medicine and Associated Factors Among Medical Interns in Amhara Regional State Teaching Hospitals, Northwest Ethiopia: Cross-sectional Study

BACKGROUND

Evidence-based medicine (EBM) is widely accepted in medicine. It is necessary to improve the knowledge and attitudes of medical students in the use of evidence. In Ethiopia, little is known about medical students' knowledge and attitudes toward EBM.

OBJECTIVE

This study aimed to assess the knowledge and attitudes toward EBM and its associated factors among medical interns in teaching hospitals.

METHODS

A cross-sectional survey was conducted using a random sample of medical interns in teaching hospitals in Ethiopia. Multivariable logistic regression analyses were used to identify the factors associated with the knowledge and attitudes toward EBM. Adjusted odds ratio (AOR) with 95% confidence interval and P≤.05 was used to quantify strength of association between variables.

RESULTS

Out of a sample of 423 medical interns, 403 completed the questionnaire (95.3% response rate). Overall, 68.0% (274/403 of respondents had a favorable attitude toward EBM and 57.1% (230/403) had good knowledge of EBM. The majority (355/403, 88.1%) of participants had internet access. Only 19.6% (79/403) of respondents had received EBM-related training. Respondents' knowledge of EBM was associated with previous EBM training (AOR 2.947, 95% CI 1.648-5.268, P<.001), understanding of sensitivity (AOR 2.836, 95% CI 1.824-4.408, P=.003), and internet access (AOR 2.914, 95% CI 1.494-5.685, P=.002). The use of an electronic database as a source of information (AOR 1.808, 95% CI 1.143-2.861, P=.01) and understanding of absolute risk reduction (AOR 2.750, 95% CI 1.105-6.841, P=.03) were predictors of positive attitudes.

CONCLUSIONS

This study demonstrates a lack of formal EBM training and awareness of basic concepts of EBM among medical interns. Medical intern attitudes toward EBM are relatively good. To enhance EBM knowledge and skills, formal teaching of EBM should be integrated into medical education.

Effect of blended learning with BOPPPS model on Chinese student outcomes and perceptions in an introduction course of health services management

Although the teaching methods of the blended learning and BOPPPS (bridge-in, objective, preassessment, participatory learning, postassessment, and summary) model are proven to be successful and highly effective at improving the academic knowledge of the students, respectively, it is unclear whether blended learning combined with the BOPPPS model (BL-BOPPPS) could work well in an introduction course of health services management (HSM) for the health management students in China. The study investigated the perceptions and effects of implementing the BL-BOPPPS model on student learning outcomes in an introduction course of HSM. The intervention group consisted of 55 students introduced to the BL-BOPPPS model, while the control group consisted of 54 students who received a conventional lecture. After the end of course, the effectiveness of teaching was self-assessed with questionnaires by all students, and examination scores for the two groups were compared. The students' satisfaction levels of BL-BOPPPS teaching strategy were up to 81.8% in the intervention group. Compared with the control group, the intervention group showed significant elevation of perception scores of skills (P = 0.001), initiative (P = 0.002), self-control (P = 0.008), self-efficacy (P = 0.001), motivation (P = 0.004), and the academic performance (P = 0.001). The BL-BOPPPS model could stimulate the enthusiasm and interest of health students; boost students' skills, initiative, and motivation in learning; and improve the self-directed learning ability, academic performance, and teaching quality. The findings provide a basis of evidence for the promotion of the BL-BOPPPS model in various disciplines in Chinese colleges and universities.

Self-reported attitudes, knowledge and skills of using evidence-based medicine in daily health care practice: A national survey among students of medicine and health sciences in Hungary

In order to map attitudes, knowledge and skills related to evidence-based medicine (EBM) in students of medical and health sciences faculties, we performed an online survey during the spring semester 2019 in all medical and health sciences faculties in Hungary. In total, 1080 students of medicine and 911 students of health sciences completed the online questionnaire. The attitude towards EBM was generally positive; however, only a small minority of students rated their EBM-related skills as advanced. There were large differences in the understanding of different EBM-related terms, with 'sample size' as the term with the highest (65%) and 'intention-to-treat analysis' with the lowest (7%) proportion of medical students being able to properly explain the meaning of the expression. Medical students who already participated in some EBM training rated their skills in searching and evaluating medical literature and their knowledge of EBM-related terms significantly better and had a more positive attitude towards using EBM in the practice than students without previous EBM training. EBM trained medical students were more likely to choose online journals (17.5% compared to 23.9%, p<0.05) and professional guidelines (15.4% compared to 6.1%, p<0.001) instead of printed books (33.6% compared to 52.6, p<0.001) as the main source of healthcare information retrieval and used Pubmed/Medline, Medscape and the Cochrane Library to a significant higher rate than students without any previous EBM training. Healthcare work experience (OR = 1.59; 95% CI = 1.01–2.52), conducting student research (OR = 2.02; 95% CI = 1.45–2.82) and upper year university students (OR = 1.65; 95% CI = 1.37–1.98) were other factors significantly influencing EBM-related knowledge. We conclude that the majority of students of medical and health sciences faculties are keen to acquire EBM-related knowledge and skills during their university studies. Significantly higher EBM-related knowledge and skills among EBM trained students underline the importance of targeted EBM education, while parallel increase of knowledge and skills with increasing number of education years highlight the importance of integrating EBM terminology and concepts also into the thematic of other courses.

Evidence based practice among healthcare providers: a cross-sectional study

PURPOSE

Nowadays health systems in most of the countries are trying to build their healthcare provision system based on scientific knowledge based evidence. Evidence-based practice (EBP) is a crucial factor for quality improvement focusing on compliance with clinical standards. The purpose of this paper is to assess evidence-based knowledge and skills among healthcare providers in Qazvin hospitals in 2016.

DESIGN/METHODOLOGY/APPROACH

This was a descriptive study conducted among 300 health professionals working in hospitals affiliated by Qazvin University of Medical Sciences in 2016. A self-administered questionnaire was used to gather data on health providers' attitude, knowledge and skill regarding EBP. Descriptive statistics and multiple linear regressions were used to analyze data using SPSS 16 software.

FINDINGS

A total of 254 participants (84.6 percent) completed the questionnaire in which their attitude, knowledge and skill toward EBP were assessed at a low level. Study results indicated that among different occupational groups, physicians and those with greater awareness toward EBP terminology had a more positive attitude compared with others. Furthermore, a higher level of knowledge and skill toward EBP was associated with being a physician and having a positive attitude toward the issue.

PRACTICAL IMPLICATIONS

Given the importance of EBP and due to insufficient knowledge of healthcare providers about the issue, it is necessary to hold appropriate educational courses to empower health workforce in implementing EBP principles.

ORIGINALITY/VALUE

The authors applied a self-administered questionnaire to assess health workforce knowledge and skills toward EBP. The results obtaining from the analysis not only highlights weaknesses related to service providers' knowledge and capabilities to implement EBP but also reveals facilities required for realization of the subject in hospital settings.

Perceptions, knowledge, and perceived barriers of Yemeni pharmacists and pharmacy technicians towards evidence-based practice

RATIONAL, AIMS, AND OBJECTIVE

The aim of this study was to assess the knowledge and perception towards evidence-based practice (EBP) and identify the perceived barriers to practicing EBP among Yemeni pharmacists and pharmacy technicians.

METHODS

A cross-sectional survey study was carried out among 153 Yemeni pharmacists and pharmacy technicians who are working in hospitals or community pharmacies. This study took place between the 15th of August and the 8th of November 2017 using a self-administered validated questionnaire. The study was approved by the ethics committee/scientific research center of Yemen University, Yemen (Reference number: ERC/2017/103).

RESULTS

Completed questionnaires were received from 153 (46.6% response rate). Most of the respondents showed a positive attitude towards EBP; however, their understanding of the basic terms used in EBP was poor (34.6%). The types of source that the respondent used in high percentage to make their decisions were own judgement and consulting the colleagues that can no longer be accurate and evidence based. The barriers to practicing EBP identified by most respondents were the limited access to EBP sources and lack of personal time.

CONCLUSION

These results reveal strong support for EBP among pharmacists and pharmacy technicians in Yemen but only a minority indicated that they understood the technical terms of EBP. Training and continuing education programs on EBP and guidelines for pharmacists are strongly needed. These findings may help in planning the use and the application of EBP process in pharmacy practice.

Cross-cultural Comparison of Pharmacy Students' Attitudes, Knowledge, Practice, and Barriers Regarding Evidence-based Medicine

Objective. To explore cultural influences on US and Japanese pharmacy students' evidence-based medicine (EBM) attitudes, knowledge, and behavior. Methods. A cross-sectional study was conducted using a self-administered survey. Senior students in one pharmacy school in the United States and two pharmacy schools in Japan were invited to complete a 33-item survey instrument. Results. Students in both countries reported having positive attitudes and understanding of EBM concepts. In their self-evaluation, American students rated their current EBM practice, EBM skills, and access to EBM resources higher than Japanese students rated themselves in these areas. The most common barriers to EBM for American students were lack of time (84.5%), lack of statistical knowledge (63.9%), and lack of critical appraisal skills (53.1%). The most common barriers to EBM for Japanese students were lack of training (92.6%), lack of clinical knowledge (90.4%), and lack of opportunity (88.8%). Conclusion. Although barriers to implementing EBM and confidence levels in using EBM differed between US and Japanese pharmacy students, both cohorts recognized EBM as an important skillset for the pharmacy profession. Culturally specific approaches to teaching EBM to pharmacy students are needed to improve EBM use in practice.

Perceptions, Perceived Barriers, and Practices of Physicians' towards Evidence-Based Medicine

Objective:

To investigate physicians’ perceptions and practices towards Evidence-Based Medicine (EBM) and physicians perceived barriers in one institute of Saudi Arabia.

Methods:

One hundred seventeen practicing physicians at King Abdulaziz University Hospital, Jeddah were included in the study. A validated questionnaire was used for collecting data. The questionnaire had four parts and included questions addressing perceptions and practices about EBM as well as associated variables and barriers to practicing it.

Results:

The majority of the respondents had a positive attitude toward EBM. Only 23.9% of participants reported that they are incorporating EBM into their practice. Knowledge about EBM databases was not good. The most common “regularly” read journal was the New England Journal of Medicine (31.6%), followed by the British Medical Journal (12.0%). Some of the respondents had an understanding and were able to explain to others the technical terms use in EBM such as odds ratio (19.7%), relative risk (22.2%), absolute risk (23.9%) and others. The major perceived barriers to practicing EBM was the lack of free personal time (27.4%), availability and access to information (27.4%), difficulties in involving in whole practice (12.0%) and lack of investment by health authorities (12.8%).

Conclusion:

The attitude of the practicing doctors towards EBM was good, but knowledge and practice were not up to the mark.

Why is there variation in the practice of evidence-based medicine in primary care? A qualitative study

OBJECTIVE

To explore the factors, including barriers and facilitators, influencing the practice of evidence-based medicine (EBM) across various primary care settings in Malaysia based on the doctors' views and experiences.

RESEARCH DESIGN

The qualitative study was used to answer the research question. 37 primary care physicians participated in six focus group discussions and six individual in-depth interviews. A semistructured topic guide was used to facilitate both the interviews and focus groups, which were audio recorded, transcribed verbatim, checked and analysed using a thematic approach.

PARTICIPANTS

37 primary care doctors including medical officers, family medicine specialists, primary care lecturers and general practitioners with different working experiences and in different settings.

SETTING

The study was conducted across three primary care settings-an academic primary care practice, private and public health clinics in Klang Valley, Malaysia.

RESULTS

The doctors in this study were aware of the importance of EBM but seldom practised it. Three main factors influenced the implementation of EBM in the doctors' daily practice. First, there was a lack of knowledge and skills in searching for and applying evidence. Second, workplace culture influenced doctors' practice of EBM. Third, some doctors considered EBM as a threat to good clinical practice. They were concerned that rigid application of evidence compromised personalised patient care and felt that EBM did not consider the importance of clinical experience.

CONCLUSIONS

Despite being aware of and having a positive attitude towards EBM, doctors in this study seldom practised EBM in their routine clinical practice. Besides commonly cited barriers such as having a heavy workload and lack of training, workplace 'EBM culture' had an important influence on the doctors' behaviour. Strategies targeting barriers at the practice level should be considered when implementing EBM in primary care.
