Using one health training for interprofessional team building: implications for research, policy, and practice in Nigeria

In recent years, the concept of One Health (OH) has arisen as an approach that helps to catalyze the creation of transdisciplinary teams needed for surveillance and investigation of emerging disease dynamics. Besides a wealth of descriptions of what the OH approach encompasses, a dearth of information is available regarding the training of individuals in OH competencies. In 2019, the Nigerian Center for Disease Control developed an OH strategic plan to meet the country's human, animal, and environmental health challenges. In response to the demand for clinicians, scientists, climatologists, conservationists, and environmentalists, who have expertise in environment, human, plant, and animal health to work collaboratively in addressing OH challenges in Nigeria. An interprofessional group of faculty from the University of Texas Medical Branch, the University of Jos, and the National Veterinary Research Institute convened to develop a novel OH course 'entitled 'One Health for Translational Team Science. The objective of the course was to explore the evolution of an emerging epidemic, capitalizing on various learning environments, including animal, environmental, human, and public health perspectives. The 6-week course comprised of three parts: 2-weeks virtual part of case-based group discussions focusing on animal and environmental aspects, 2 weeks of individual field experiences, and a final virtual part focusing on human health. Pedagogical tools used were: case-based group discussions, breakout group presentations, role-play activities, field project write-up, peer evaluation, group writing assignments, and weekly reflections with the goal of working in teams to develop and practice the fundamental leadership and management skills in addressing emerging public health challenges. Post-course evaluations showed that all participants felt more confident identifying and practicing the necessary attitudes and skills to participate effectively in the evaluation of an outbreak. Furthermore, the roles, responsibilities, and "One Health ways of thinking" for the various disciplines and professions involved in improving global health were articulated and identified.

Exploring the potential impact of applying web-based training program on nurses' knowledge, skills, and attitudes regarding evidence-based practice: A quasi-experimental study

Evidence-based practice (EBP) has gained significant importance in clinical practice worldwide, including in nursing. This study aimed to explore the potential impact of applying a web-based training program on nurses' knowledge, skills, and attitudes regarding EBP. A quasi-experimental pretest-posttest research design was utilized with a purposive sample of 64 professional nurses who agreed to participate. The study took place in different hospitals and primary healthcare centers in the Bisha Governorate, Aseer region, Saudi Arabia. A four-week standardized web-based training program was implemented using an online learning approach. Nurses were provided with an online self-rated data collection tool through the Google Forms platform. The findings indicated a highly significant difference in the total knowledge and EBP skills mean scores of the post-intervention (53.08±15.9) and (66.03±8.95), respectively compared to pre-intervention (P<0.05). Additionally, there was marked improvement in the mean scores of the positive attitude of the training sessions post-intervention compared to pre-intervention. The program was also well-received by the nurses in terms of quality and usability. The program has the potential to enhance nurses' knowledge, skills, and attitudes toward EBP. Therefore, healthcare organizations may consider adopting web-based training as a means of continuing professional education to promote EBP competencies among nurses.

Effectiveness of electronic learning for continuing interprofessional education on behavior change of healthcare professionals: A scoping review

Electronic learning (e-learning) for continuing professional education (CPE) in healthcare has been shown to improve learners' satisfaction, attitudes, and performance. E-learning outcomes for continuing interprofessional education (CIPE) are less known, and the features of electronic CIPE programs that promote behavior change are unclear. In this scoping review, we sought to identify the program features and areas of behavior change in healthcare professionals using e-learning for CIPE. PubMed, CINAHL, ERIC, PsycINFO, Cochrane Library databases, and Google/Google Scholar were searched for all English articles published in the last 10 years. From the 32 studies included in our review, eight types of e-learning methods were identified. More than 35,542 healthcare professionals of different professions had participated in the programs. Thirty studies demonstrated positive behavior changes, with four areas of behavior changes identified. The most common area of change was in patient care practices. Five common program features facilitating behavior change were also identified. Most successful programs provided interactive and authentic learning experiences, which promoted direct clinical application. Future researche should include monitoring of sustained behavior changes at work, linked to patient outcomes.

Effectiveness of an Evidence-Based Practice Training Program for Nurse Educators: A Cluster-Randomized Controlled Trial

BACKGROUND

Evidence-based practice (EBP) endeavors to integrate the best available evidence with clinical expertise and patient preference to enhance clinical outcomes. For nurses to effectively demonstrate EBP, the concepts of EBP should be systematically incorporated into the nursing curriculum, with nurse educators playing a pivotal role in execution. However, the effect of EBP training programs on nurse educators remains largely unexplored.

AIM

To evaluate the effectiveness of an EBP training program on the knowledge, attitude, practice, and competency of nurse educators.

METHODS

A pragmatic randomized controlled trial was conducted at a nursing education institution. Fifty-one nurse educators were cluster randomized into intervention and control groups. A 30-hour EBP training intervention was provided for nurse educators in the intervention group. The outcome variables were knowledge, attitude, practice, and competency regarding EBP. These outcomes were evaluated using the EBP knowledge and practice questionnaire, EBP attitude scale, and Fresno test. Data were collected at baseline, the end of 5 months, and the end of 10 months.

RESULTS

Fifty-one eligible participants were enrolled in the study. The intervention and control group had three clusters each with 27 and 24 participants, respectively. Participants in both groups were comparable for variables such as age, years of experience, and educational background (p > .05). Between groups, outcome variables were compared using mixed linear multi-level modeling. Nurse educators who received the EBP training program demonstrated significant differences in knowledge (p < .05), attitude (p < .05), practice (p < .05), and competency scores (p < .05), than that of the control group, indicating the intervention effectiveness.

LINKING EVIDENCE TO ACTION

EBP training programs are effective in improving the knowledge, attitude, practice, and competency of nurse educators.

A Quasi-Experimental Study of a Basics of Evidence-Based Practice Educational Intervention for Health and Social Care Professionals

Education is one of the central interventions to promote evidence-based practice (EBP) in service organizations. An educational intervention to promote EBP among health and social care professionals was implemented in a Finnish hospital. The aim of this study was to explore the outcomes of an educational intervention, focusing on the basics of EBP for health and social care professionals, using a quasi-experimental study design. The data were collected with a questionnaire before, immediately after, and 6 months after the education (n = 48). The data were analyzed with descriptive statistics and nonparametric tests. Immediately after the education, an increase was found in the EBP knowledge of participants, in participants’ confidence in their own ability to conduct database searches and read scientific articles, and in the number of participants using databases at work. Six months after the education, improvements were still found between the first and the third measurement in the participants’ knowledge and confidence in their own ability to conduct database searches and read scientific articles. The number of those who had made an initiative about a research topic regarding the development of their own work had increased from the first to the third measurement. The educational intervention produced a statistically significant improvement on most of the areas evaluated. Significant improvements were often found even 6 months after the education was finished. However, the low completion rate and a quasi-experimental before and after design limit the conclusions that can be derived from this study.

What Does Evidence-Based Practice Mean to You? A Follow-Up Study Examining School-Based Speech-Language Pathologists' Perspectives on Evidence-Based Practice

Purpose The current investigation is a follow-up from a previous study examining child language diagnostic decision making in school-based speech-language pathologists (SLPs). The purpose of this study was to examine the SLPs' perspectives regarding the use of evidence-based practice (EBP) in their clinical work. Method Semistructured phone interviews were conducted with 25 school-based SLPs who previously participated in an earlier study by Fulcher-Rood et al. 2018). SLPs were asked questions regarding their definition of EBP, the value of research evidence, contexts in which they implement scientific literature in clinical practice, and the barriers to implementing EBP. Results SLPs' definitions of EBP differed from current definitions, in that SLPs only included the use of research findings. SLPs seem to discuss EBP as it relates to treatment and not assessment. Reported barriers to EBP implementation were insufficient time, limited funding, and restrictions from their employment setting. SLPs found it difficult to translate research findings to clinical practice. SLPs implemented external research evidence when they did not have enough clinical expertise regarding a specific client or when they needed scientific evidence to support a strategy they used. Conclusions SLPs appear to use EBP for specific reasons and not for every clinical decision they make. In addition, SLPs rely on EBP for treatment decisions and not for assessment decisions. Educational systems potentially present other challenges that need to be considered for EBP implementation. Considerations for implementation science and the research-to-practice gap are discussed.

In what ways does online teaching create a positive attitude towards research in nursing students studying a first year evidence-based practice undergraduate subject online?

Nursing research teaching is seen as central to nurse education and practice, but the impact of exposure to research teaching on students' attitudes towards research remains unclear. The aims of this study were to explore the attitudes towards research of undergraduate nursing students, before and after exposure to research teaching online. A further aim of this study was to better understand students' attitudes towards research, to inform future teaching strategies. This descriptive quasi-experimental study used pre-semester and post-semester data collected by means of an online questionnaire. The Attitudes Towards Nursing Research Scale measured student attitudes via 18 Likert items that assessed four domains: Research Abilities, Usefulness of Research, Personal Interest in Research and Using Research in Clinical Practice. There were no statistically significant changes in the overall Attitude Towards Research Scale. Individual item analysis did show statistically significant changes in two items: Understanding of research terminology increased (p = 0.001), but Intention to conduct research decreased (p = 0.035). This study generated evidence on attitudes of nursing students toward research before and after their exposure to a research subject. Research teaching online may be insufficient to effect a change in student nurses' attitudes towards research. SUMMARY OF RELEVANCE: Issue: Research is a foundational topic in undergraduate nursing curricula, but students often find the topic to be challenging to learn, while academics find it challenging to engage students in learning about research.What is Already Known: A validated instrument, Attitudes Towards Research, can be used to ascertain if teaching affects attitudes.What this Paper Adds: Overall attitudes of first year, second semester students did not change after experiencing a semester long introductory research subject. However, two item statements did show a statistically significant change, in disparate directions. Understanding of Research Terminology increased, while Intention to Conduct Research decreased.

Closing the Gap: A Regional Partnership Model for Perioperative Nursing

New Jersey is projected to be one of the top three states to experience a nursing shortage. The current practice of health care organizations providing their own education and training in the perioperative setting leads to variability in the degree of staff readiness and competence to address the complexities encountered in this setting. This may result in increased perioperative nursing orientation costs. The Center for Professional Development at Rutgers School of Nursing partnered with members of the region's surgical facilities to design and implement an accelerated immersion perioperative training model. This academic-clinical practice partnership resulted in a model that equips nurses with the competencies to better fulfill workforce demands while reducing costs.

Competences and Barriers for the Evidence-Based Practice in Nursing: an integrative review

ABSTRACT Objective: To analyze knowledge, attitudes, practices, and frequent barriers to the implementation of the Evidence-Based Practice among nursing assistants in the hospital. Method: This is an integrative review, whose search for primary studies occurred in the PubMed, CINAHL and LILACS databases. For the analysis, cross-sectional observational studies were included in English, Portuguese and Spanish, published in nursing journals, from January 2007 to July 2016. Results: The search resulted in 363 articles, including nine primary studies. The sources of recurrent evidence among care nurses were: personal experience and local care protocols. These professionals presented weaknesses in the implementation of the Evidence-Based Practice related to the lack of knowledge for evidence evaluation, work overload and resistance to change of practice. Final considerations Nurses presented favorable attitudes, however, with little knowledge to perform the Evidence-Based Practice. Results can support interventions for its implementation in the hospital.

Educational interventions promoting evidence-based practice among emergency nurses: A systematic review

INTRODUCTION

Emergency nurses are expected to adopt evidence-based practice (EBP). The aim of this systematic review was to describe educational interventions promoting EBP and their outcomes among emergency nurses, compared with no education, to inform clinicians and researchers about effective educational interventions suitable for use in emergency departments (EDs).

METHODS

CINAHL, Cochrane, PubMed and Scopus were systematically searched to identify studies published between January 1, 2006 and October 20, 2016 describing educational interventions designed to promote EBP among emergency nurses. 711 studies were identified and screened; 10 were selected for inclusion and quality assessment. The studies were analyzed using deductive content analysis, and the review's results are presented in accordance with the PRISMA guidelines.

RESULTS

Ten relevant studies on nine different self-developed educational interventions were identified. Eight studies had highly significant or significant results. Interventions involving face-to-face contact led to significant or highly significant effects on patient benefits and emergency nurses' knowledge, skills, and behavior. Interventions using written self-directed learning material led to significant improvements in nurses' knowledge of EBP. All the descriptions of the interventions were incomplete, and the reported details varied considerably between the studies.

CONCLUSIONS

There have been few studies on educational interventions to promote EBP among emergency nurses but the available results are promising.

Application of a Q Method Study to Understanding Nurses' Perspective of Adopting Evidence-Based Nursing

PURPOSE

This study applied the Q method to identify and describe the various types of nurse perceptions that are crucially associated with their engagement in evidence-based nursing (EBN).

METHODS

The study participants were nurses at a medical center and a regional teaching hospital. A series of Q sorts was performed by nurses to subjectively rank the Q statements. Q statements were constructed based on the literature related to EBN adoption by nurses and face-to-face interviews.

RESULTS

A total of 60 participants were invited to rank 44 Q statements related to EBN. Factor analysis was conducted on the rankings of the Q statements. The following are the five prominent shared perspectives: (1) emphasized the obstacles to evidence searching and reading ability; (2) emphasized the organizational promotive strategies; (3) emphasized the available supportive resources; (4) emphasized the significance of EBN; and (5) emphasized the evidence-searching ability and external incentives. The five identified groups of perspectives can enhance hospital administrators to acknowledge the barriers and incentives associated with EBN practices.

CONCLUSION

The exploration of clustering nurses' perceptions may facilitate the development of customized strategies to enable more appropriate training.

OBJECTIVES Identify individual barriers in the implementation of evidence-based practice (EBP) by nurses. Describe interventions of the programs reviewed in the article that directly affect barriers to clinical nurses' adoption of EBP or the use of research. DISCLOSURE STATEMENT Neither the planners nor the author have any conflicts of interest to disclose.

BACKGROUND

Individual barriers such as a lack of research awareness, electronic database navigation skills, and research comprehension prevent nurses from implementing evidence-based practice (EBP). The aim of this review article is to examine EBP programs and their influence on individual barriers among workforce nurses.

METHOD

A keyword search of online databases was conducted for original research published from 2004- 2015. A review of cited references and footnote searching of significant articles was conducted to identify additional relevant articles.

RESULTS

Twenty articles met the inclusion criteria. Although there was great variation among EBP programs, the majority of participants reported increased awareness, value, belief, knowledge, and skill as it relates to research utilization and EBP.

CONCLUSION

This review suggests that individual barriers to EBP may be influenced by clinically based EBP programs. However, a lack of randomized controlled studies and inconsistencies in measurement make it difficult to recommend best practices for developing EBP programs for nurses in the clinical setting. J Contin Educ Nurs. 2016;47(9):398-406.

Using Research Findings to Design an Evidence-Based Practice Curriculum

Evidence from a system-wide research study highlighted strengths and weaknesses in evidence-based practice (EBP) implementation, beliefs, and organizational readiness. To address this evidence, a curriculum was developed within the context of the shared governance and EBP models for nursing practice. The curriculum, Evidence-Based Practice: Clinical Applications in Professional Nursing Practice, consists of five modules that provide the knowledge, skills, and abilities relative to each step of EBP. The learning approach incorporates classroom- and unit-based education, facilitated by EBP curriculum mentors. Each module is rolled out quarterly for a 15-month curriculum cycle. Outcome data include pre- and post-learning assessments, in addition to EBP projects. This seamless approach to nursing education, based on research findings and established shared governance and EBP models, can be undertaken by community hospital systems.

Effectiveness of an Evidence-Based Practice Nurse Mentor Training Program

BACKGROUND

Multiple reasons are cited for why nurses do not incorporate evidence into clinical practice, including lack of knowledge and skills, training, time, and organizational support.

AIMS

To investigate the effectiveness of a mentor training program on mentors' perceptions of knowledge, attitude, skill, and confidence levels, and organizational readiness related to evidence-based practice (EBP) and research utilization; and to investigate the effectiveness of creating a formalized structure to enculturate EBP in order to prepare nurses to incorporate EBP into clinical practice on nurses' perceptions of knowledge, attitude, skill levels, barriers, nursing leadership, and organizational support related to EBP and research utilization.

METHODS

A two-group pretest-posttest quasi-experimental, interventional design was used. A convenience sample of 66 mentors and 367 nurses working at a five hospital integrated healthcare system located in the Southeastern United States participated.

FINDINGS

Nurse mentors' knowledge, attitude, skill level, and organizational readiness related to EBP, t = -8.64, p < .001, and confidence, t = -6.36, p < .001, improved after training. Nurses' knowledge, attitude, and skill level related to EBP, t = -19.12, p < .001, and barriers to research utilization, t = 20.86, p < .001, EBP work environment t = -20.18, p < .001, and EBP nurse leadership, t = -16.50, p < .001, improved after a formalized structure was implemented.

LINKING EVIDENCE TO ACTION

EBP mentors are effective in educating and supporting nurses in evidence-based care. Leaders should use a multifaceted approach to build and sustain EBP, including developing a critical mass of EBP mentors to work with point of care staff.

Future Rehabilitation Professionals' Intentions to Use Self-Management Support: Helping Students to Help Patients

Purpose: We evaluated whether education in self-management support (SMS) increases future clinicians' intentions to use a new way of delivering rehabilitation services. Methods: A convenience sample of 10 students took a 5-week theoretical course, followed by 6 weeks spent assessing patients, establishing treatment plans, and monitoring their performance by telephone. Focus groups were held before and after the educational modules, with deductive mapping of themes to the Theory of Planned Behaviour and inductive analysis of additional themes. Results: Five themes and 22 subcategories emerged from the deductive-inductive focus group content analysis. After participating in the educational modules, students reported gaining knowledge about SMS and highlighted the lack of similar preparation during their academic courses. Nonetheless, they were hesitant to adopt SMS. Conclusion: Future clinicians gained knowledge and skills after being exposed to SMS courses, but their intention to adopt SMS in their future daily practice remained low. We also noted a lack of formal training in SMS in the academic setting. The findings from this study support incorporating SMS training into the curriculum, but to increase students' intention to use SMS as part of patient care, training may need to be in more depth than it was in the modules we used.

Educational interventions on evidence-based nursing in clinical practice: A systematic review with qualitative analysis

AIMS

To gather, assess and synthesise the currently available evidence of educational interventions on evidence-based nursing (EBN).

BACKGROUND

Previous systematic reviews have focused on the items used in reporting educational interventions for facilitating evidence-based practices in medicine and health care or teaching research literacy in nursing as well as on the outcomes of these interventions.

DESIGN

A systematic review based on a procedure of the Centre for Reviews and Disseminations for conducting a systematic review of health interventions.

DATA SOURCES AND METHODS

Texts from 2008 to 2015 were sought from the Cochrane, CINAHL and PubMed Medline databases. Eight studies were selected for the final data and reviewed for quality. Data were analysed with narrative synthesis including qualitative content analysis.

RESULTS

Four main categories and sixteen subcategories were identified. The learning contents included principles of EBN and research, the process of EBN, and planning a change in practice. The most popular teaching/learning methods were lectures/didactic presentations and group work. The interventions encouraged learners to critically examine and evaluate their practice. The interventions also improved participants' capacity to identify the need for research evidence in clinical practice.

CONCLUSION

The educational interventions were fairly similar and had promising results. However, as the level of evidence was modest in the studies, there are several development needs for interventions and further research challenges. Interventions should provide participants with sufficient competences for implementing every step of EBN, with special focus on the implementation of evidence in patient care. The assessment of the outcomes of interventions should cover all learning categories of EBN with focus on medium to long-term effectiveness. The influence of different teaching/learning methods and learning contexts and settings should be investigated further.

Assessing Attitudes Toward Evidence-Based Practices of Workers Supporting People With Disabilities: A Validation of the Evidence-Based Practice Attitudes Scale

This study conducted an initial psychometric validation of the Evidence-Based Practice Attitude Scales (EBPAS; Aarons, 2004 ) with a sample of workers employed in services that offer support to people with disabilities. Workers completed an online survey containing the EBPAS-GEN (a disability services version) and EBPAS-PBS (a version focused on positive behavior support, an evidence-based practice used in disability services). Confirmatory factor analysis, group differences, and internal consistency results support the psychometric soundness of both versions; however, the EBPAS-GEN shows slightly weaker properties. Evidence-based practice is gaining attention in the disability literature, and these findings add to this body of knowledge. These initial findings support the use of both versions of the EBPAS with populations of workers who work within disability services.

Evaluation of an Evidence-Based Practice Tutorial for Nurses: A Useful Tool and Some Lessons Learned

Although evidence-based practice (EBP) and research is important to hospitals and nursing staff interested in achieving Magnet status, a more important purpose is the improvement of patient care. As the nursing staff of UConn Health and its John Dempsey Hospital began its initial assessment prior to embarking on the journey for Magnet status, staff nurses were found to lack skills in searching vetted sources of EBP literature and appraising the results of a search. To address this need, a librarian at UConn Health, in collaboration with the hospital's Nursing Research steering committee, developed an online, self-paced EBP tutorial. The EBP tutorial used the iterative (Analysis, Design, Development, Implementation, and Evaluation) model of instructional design in development and assessment. This article describes the development and implementation of the tutorial, its evaluation, and lessons learned. J Contin Educ Nurs. 2016;47(6):266-271.

The state of readiness for evidence-based practice among nurses: An integrative review

OBJECTIVES

To review factors related to nurses' individual readiness for evidence-based practice and to determine the current state of nurses' evidence-based practice competencies.

DESIGN

An integrative review study.

DATA SOURCES

Thirty-seven (37) primary research studies on nurses' readiness for evidence-based practice, of which 30 were descriptive cross-sectional surveys, 5 were pretest-posttest studies, and one study each was an experimental pilot study and a descriptive qualitative study. Included studies were published from the beginning of 2004 through end of January 2015.

REVIEW METHODS

The integrative review study used thematic synthesis, in which the quantitative studies were analyzed deductively and the qualitative studies inductively. Outcomes related to nurses' readiness for evidence-based practice were grouped according to the four main themes that emerged from the thematic synthesis: (1) nurses' familiarity with evidence-based practice (EBP); (2) nurses' attitudes toward and beliefs about evidence-based practice; (3) nurses' evidence-based practice knowledge and skills; and (4) nurses' use of research in practice. Methodological quality of the included studies was evaluated with Joanna Briggs Institute critical appraisal tools.

RESULTS

Although nurses were familiar with, had positive attitudes toward, and believed in the value of EBP in improving care quality and patient outcomes, they perceived their own evidence-based practice knowledge and skills insufficient for employing evidence-based practice, and did not use best evidence in practice. The vast majority (81%) of included studies were descriptive cross-sectional surveys, 84% used a non-probability sampling method, sample sizes were small, and response rates low. Most included studies were of modest quality.

CONCLUSIONS

More robust, theoretically-based and psychometrically sound nursing research studies are needed to test and evaluate the effectiveness of interventions designed to advance nurses' evidence-based practice competencies, especially teaching them how to integrate evidence-based practice into clinical decision-making. All efforts should be focused on systematically using knowledge transformation strategies shown to be effective in rigorous studies, to translate best evidence into practice-friendly, readily usable forms that are easily accessible to nurses to integrate into their clinical practice.
