Being and Becoming an Evidence-Based Practitioner: Occupational Therapists' Journey Toward Expertise.

IMPORTANCE: Despite mounting evidence for the management of various health care conditions, the uptake of scientific evidence in occupational therapy is often suboptimal. Although positive attitudes and self-efficacy are key to evidence-based practices (EBPs), how one becomes an evidence-based practitioner, and how expertise in EBP manifests in practice, remains unclear. OBJECTIVE: To describe how expert evidence-based practitioners conceptualize and enact their expertise in stroke rehabilitation. DESIGN: Qualitative interpretive descriptive study using in-depth semistructured interviews with eight occupational therapists identified as expert evidence-based practitioners in a previous study. Transcripts were analyzed using an inductive thematic content analysis, and emergent themes were identified. SETTINGS: Rehabilitation settings across Canada. RESULTS: Six overarching themes emerged: (1) relying on personal attributes to engage in practice improvement, (2) acting on factors that motivate and trigger EBP, (3) achieving better outcomes because of engagement in EBP, (4) using an adaptive decision-making process, (5) participating in professional activities that contribute to practice improvement, and (6) working in a practice area with a large body of evidence. CONCLUSIONS AND RELEVANCE: Expertise in stroke rehabilitation EBP appears to be a function of several personal attributes and habits of mind in addition to being influenced by a commitment to client-centered practice. Expertise requires a combination of deliberate effort and motivation to improve client outcomes, always in a context conducive to reflection, adaptation, and openness to innovation. Experts who model these traits and articulate the processes used to develop their expertise can be viewed as promising educational and continuing professional development resources. What This Article Adds: Expert evidence-based occupational therapists develop their expertise in this domain through commitment to client-centered practice, efforts toward honing this aspect of practice, and a willingness to innovate and adapt to challenging situations.

Stakeholders' priorities in the development of evidence-based practice competencies in rehabilitation students: a nominal group technique study.

PURPOSE: Clinically integrated teaching (CIT) is an effective approach for promoting evidence-based practice (EBP) competencies among medical students. Challenges towards the implementation of CIT in rehabilitation curricula include educators' different conceptualizations of EBP, the perceived complexity of EBP and the boundaries between the academic and the clinical setting. This study aimed to identify tailored strategies to implement in rehabilitation programs and their affiliated clinical sites to support the development of EBP competencies among students in occupational therapy (OT), physical therapy (PT) and speech-language pathology (S-LP). MATERIALS AND METHODS: Nominal group technique (NGT) with stakeholders from three rehabilitation programs in Canada, offering the professional master's in OT and PT (n = 35 participants) and in S-LP (n = 8). RESULTS: The top two strategies identified in the OT/PT NGT were: 1) Developing a flexible definition of EBP that recognizes its complexity; 2) Providing clinicians with more access to the teaching content by pairing faculty with preceptors. The top two strategies identified in the S-LP NGT were: 1) Providing students with opportunities for decision-making with experienced clinicians; 2) Increasing interactions between faculty and preceptors using formal group meetings. CONCLUSION: Findings laid foundations for future integrated knowledge translation projects to collaboratively implement, and test identified strategies.

Rehabilitation professions including occupational therapy, physical therapy and speech-language pathology acknowledge the importance of evidence-based practice (EBP).Current challenges in the teaching of EBP among rehabilitation students include educators' different conceptualizations of EBP, the perceived complexity of EBP, and the boundaries between the academic and the clinical setting.This study shows that increasing interactions between faculty and preceptors, for instance through an online community of practice, constitutes a stakeholder-endorsed priority to advance EBP education in rehabilitation.

Ultra-Wide-Field Fluorescein Angiography Assessment of Non-Perfusion in Patients with Diabetic Retinopathy Treated with Anti-Vascular Endothelial Growth Factor Therapy.

Purpose: To follow the evolution of peripheral ischemia by fluorescein angiography (FA) on ultra-wide-field (UWF) images in diabetic patients treated with anti-vascular endothelial growth factor (anti-VEGF) for macular edema. Methods: Prospective, non-interventional cohort study analyzing UWF-FA images of 48 patients with diabetic retinopathy (48 eyes) treated for diabetic macular edema. UWF-FA was performed at baseline and after one year of anti-VEGF therapy (M12). The primary endpoint was the change in the non-perfusion index. Results: Of the 48 patients included in this study, 25 completed the one-year follow-up, and 20 had FA images of sufficient quality to be interpreted. The non-perfusion index did not significantly change from baseline after one year of anti-VEGF treatment (0.7% of the non-perfused area at baseline versus 0.5% at M12; p = 0.29). In contrast, the diabetic retinopathy severity score improved significantly between baseline and M12. Conclusions: Anti-VEGF treatment with aflibercept for diabetic macular edema had no impact on the retinal perfusion assessed by FA, but it allowed for artificially improving diabetic retinopathy severity scores.

Macular toxicity of vital dye after pars plana vitrectomy for idiopathic epiretinal membrane: A case report.

Purpose: To describe the first reported case of outer retinal damage following the use of Membrane Blue Dual for epiretinal membrane (ERM) surgery. Observations: A 74-year-old female underwent pars plana vitrectomy and ERM peeling assisted with Membrane Blue Dual for an idiopathic ERM. Postoperatively, the patient reported a decline in visual acuity with a central scotoma. Fundus examination revealed a well-defined retinal whitening in the peeling area which evolved into pigmentary changes as confirmed by fundus autofluorescence. Optical coherence tomography (OCT) showed loss of outer retinal layers and irregular mottling of the retinal pigment epithelium. Fundus and OCT appearance remained unchanged after 4 months and the central scotoma also persisted. Conclusions and Importance: ERM surgery assisted with Membrane Blue Dual can induce major changes in retinal pigment epithelium and outer retinal layers. This adverse event which probably results from combined light and dye toxicity should be considered by all surgeons even though its occurrence is rare.

Comparison of Ultra-Wide Field Photography to Ultra-Wide Field Angiography for the Staging of Sickle Cell Retinopathy.

Sickle cell retinopathy (SCR) is classified by Goldberg based on peripheral vascular changes. Ultra-wide field (UWF) imaging has enhanced visualization of the peripheral retina. However, there is no consensus on the optimal imaging technique for the screening of SCR. We performed a monocentric observational cross-sectional study to compare UWF fundus photography (UWF-FP) with UWF angiography (UWF-FA). All patients who underwent UWF-imaging (Optos, PLC, Scotland, UK) for screening of sickle cell retinopathy between January 2016 and December 2019 were retrospectively included. Eyes with previous laser treatment or concomitant retinal disease were excluded. UWF-FP images were graded based on the Goldberg classification by four graders with various degrees of experience. UWF-FA pictures were reviewed by an independent retina specialist. Differences in Goldberg staging across UWF-FP and UWF-FA were assessed. A total of 84 eyes of 44 patients were included. Based on UWF-FA, most eyes were stage 2 (77.4%) and 19 were stage 3 (22.6%). The pre-retinal neovascularization detection sensitivity on UWF-FP was 52.6 to 78.9%, depending on the graders. UWF-FA led to a later Goldberg stage of retinopathy, in most cases from stage 1 to stage 2. Neovascularization (stage 3) was not detected by our graders on UWF-FP in 21.1 to 57.9% of eyes. UWP-FP tends to underestimate Goldberg stages of retinopathy compared with UWF-FA and is less accurate when detecting neovascularization in sickle cell retinopathy, which has a direct impact on therapeutic management and prognosis.

Individual and organizational factors associated with evidence-based practice among physical and occupational therapy recent graduates: A cross-sectional national study.

BACKGROUND: Occupational therapy (OT) and physical therapy (PT) programs in Canada have moved to graduate-level entry education to address graduates' readiness for evidence-based practice (EBP). Whether rehabilitation professionals with advanced training in EBP are meeting their responsibilities as evidence-based professionals upon entry into practice and the factors that influence the use of evidence is unclear. The aim of this study was to examine the individual and organizational factors associated with the use of EBP and supporting evidence-based activities among graduates of professional OT and PT master's programs. METHODS: A cross-sectional design using a survey of recent graduates of the 29 OT and PT programs in Canada. The survey measured six constructs supportive of EBP (ie, knowledge, attitudes, confidence, organizational resources, actual use of EBP, and evidence-based activities). Analyses consisted of descriptive statistics to characterize the sample and the different variables and ordinal multivariate regression analysis. RESULTS: 257 graduates (15%) completed the survey. Attitudes towards EBP was positively associated both with evidence-based activities (odds ratio = 1.36 with a 95% CI: 1.22 to 1.52) and use of EBP (odds ratio = 1.23 with a 95% CI: 1.12 to 1.36); greater confidence was related to greater use of EBP (OR = 1.12, 95% CI: 1.01 to 1.24); and working in a private practice setting was found to be related to performing more evidence-based activities (odds ratio = 3.15, 95% CI: 1.40 to 7.12). CONCLUSIONS: Despite a greater focus on EBP knowledge in these curricula across Canada, knowledge was not related to EBP use nor evidence-based activities upon entry into practice. On the other hand, attitudes, confidence and working in private practice were. University programs should consider curricular strategies that increase the use of EBP, provide opportunities to engage in evidence-based activities with an emphasis on promoting the development of positive attitudes towards EBP and increasing learners' confidence in their ability to be evidence-based professionals.

Ethnic differences in normal retinal capillary density and foveal avascular zone measurements.

BACKGROUND: The purpose of this study was to quantify retinal capillary density and foveal avascular zone (FAZ) area in healthy subjects according to their ethnicity, using optical coherence tomography angiography (OCTA). METHODS: In this cross-sectional study, all eyes underwent swept-source OCTA (Triton, Topcon, Tokyo, Japan). Macular OCTA scans (3 × 3 mm) were obtained in healthy white Caucasian and black African subjects. The FAZ area and capillary density in both the superficial (SCP) and deep capillary plexuses (DCP) were automatically measured using a custom-made software combining vessel binarization and skeletonization. RESULTS: Twelve eyes of 12 healthy Caucasians and 15 eyes of 15 healthy black Africans were included in the analysis. The mean FAZ area was significantly smaller, and the overall vessel density (VD) was higher in the SCP and DCP of Caucasians compared to black Africans. The mean FAZ area was 0.26 ± 0.008 mm2 in the SCP and 0.25 ± 0.05 mm2 in the DCP in Caucasians versus 0.33 ± 0.08 mm2 in the SCP (p = 0.01) and 0.37 ± 0.1 mm2 in the DCP (p = 0.03) in Africans. In the SCP and DCP, the mean VD was, respectively, 40.5 ± 0.8% and 47.1 ± 0.5% in Caucasians versus 34.3 ± 1% (p = 0.008) and 40.6 ± 0.9% in Africans (p < 0.001). DISCUSSION/CONCLUSION: In the SCP and DCP, VD is lower in black Africans compared to Caucasians. In OCTA studies on vascular diseases, ethnicity-matched measurements from healthy subjects should be used for comparisons.

What occupational therapists' say about their competencies' enactment, maintenance and development in practice? A two-phase mixed methods study.

BACKGROUND: Understanding how professional competencies are actually enacted in clinical practice can help university programs better prepare their graduates. The study aimed to describe 1) the perceived competency level of occupational therapists holding an entry-to-practice master's degree 2) the factors perceived as impacting the enactment of competencies; and 3) the strategies used to maintain and further develop level of competency in the seven practice roles: expert in enabling occupation, communicator, collaborator, practice manager, change agent, scholarly practitioner and professional. METHODS: Descriptive two-phase mixed methods sequential design. The quantitative phase consisted of an online survey sent to all occupational therapists holding an entry-to-practice master's degree in Quebec, Canada (n = 1196), followed by focus group discussions with a subset of participants. Analysis used descriptive statistics and the Framework Approach for content analysis of focus group data. Competencies were theoretically anchored into the Profile of Occupational Therapist Practice in Canada (an equivalent to CanMEDS framework) and we used the Theoretical Domain Framework to collect and describe perceived factors and strategies. RESULTS: Response rate to Phase 1 was 26.5% (n = 317/1196). The communicator, collaborator and professional roles were perceived as highly solicited in practice, valued and were rated more frequently at a higher competency level as compared to the other four roles (expert, manager, change agent and scholar roles). Focus group participants (n = 16) mentioned that both individual and organisational factors influence enactment of competencies. Consulting colleagues was the preferred strategy to support the scholar role, often described as foundational for the development of expertise. CONCLUSION: This descriptive study provides valuable information as to how the seven roles are enacted in practice. Though the scholar role is highly valued by clinicians and organizations, insufficient time is allotted to searching for evidence and reflection in practice. Strategies emerging from the results are mainly directed toward this role with an emphasis on using of peers as a source of evidence. Future studies could explore how contextual factors influence the enactment of competencies across different professions as well as how these evolve over time.

Optical Coherence Tomography Angiography of Macula in Chronic Anterior Ischaemic Optic Neuropathy Associated with Giant Cell Arteritis.

A 74-year-old man presented with bilateral optic nerve atrophy related to arteritic anterior ischaemic optic neuropathy (AION) which started 22 years ago. Atrophic papilla was noted in both eyes and optical coherence tomography showed thinning of the retinal nerve fibres layer as well as the macular ganglion cell complex. Optical coherence tomography angiography of the macula found a decreased density of the superficial capillary complex, whereas deep capillary complex was well-preserved. Inner retinal layer atrophy in chronic arteritic AION is followed by a loss of vascularisation in these layers as a consequence of the neurodegeneration.

A Web-Based Physical Activity Portal for Individuals Living With a Spinal Cord Injury: Qualitative Study.

BACKGROUND: The population with a spinal cord injury (SCI) largely remains inactive following discharge from rehabilitation despite evidence on the benefits of physical activity. These individuals need to develop skills to self-manage their condition in order to prevent secondary comorbidities and rehospitalization. A Web-based physical activity portal can address this need. Few Web-based interventions incorporate theoretical frameworks, behavior change techniques, and modes of delivery into their design. OBJECTIVE: This study aimed to identify the preferred features of a Web-based self-management physical activity portal through stakeholder engagement with individuals with a spinal cord injury and health care professionals (HCPs). METHODS: An interpretative phenomenology methodology and participatory design, along with an integrated knowledge translation approach, were used to conduct this study. Convenience sampling was used to recruit individuals with an SCI living in the community, who were either interested or already engaging in physical activity, and HCPs working with individuals with an SCI, from three city-based rehabilitation sites. Individual 1-hour sessions involving navigation of an existing website and a semistructured interview were conducted with all participants. Individuals with an SCI completed a demographics questionnaire prior to the individual sessions, while demographic information of the HCPs was collected during their interviews. Additionally, all participants were asked a question on their intention to use or recommend a portal. An in-depth thematic analysis was used to derive themes from participants' responses. RESULTS: Thirteen individuals with an SCI and nine HCPs participated in the study. Five core themes emerged: (1) knowledge: guidance and barrier management; (2) possibility of achievement: the risks and benefits of physical activity and modelling; (3) self-regulation strategies: action planning, goal setting, tracking, rewards, and reminders; (4) interactivity: peers and professionals; and (5) format: appearance, language, and ease of use. The mean (median) ratings of the likelihood of promoting and using a Web-based portal tailored to individuals' needs were 9.00 (8.78) and 7.75 (7.88) for HCPs and individuals with an SCI, respectively. CONCLUSIONS: This study highlights features of an online self-management platform that can provide individuals with an SCI the motivation and volition to engage in physical activity. These findings will inform the design of a Web-based self-management physical activity portal to increase physical activity adherence and behavior change.

Use of evidence in health professions education: Attitudes, practices, barriers and supports.

Introduction: Health professions educators are increasingly called upon to apply an evidence-informed approach to teaching and assessment practices. There is scant empirical research exploring educators' attitudes, practices, and perceived barriers and supports to using research evidence in educational practice. Methods: We conducted a survey of AMEE members to explore three domains related to evidence-informed health professions education: (1) attitudes; (2) practices; and (3) supports and barriers. Analyses involved descriptive statistics to characterize participants' responses per domain, exploratory factor analysis, and multivariate regression analyses. Results: Three hundred ninety-six (∼10%) participants representing health professions educators (HPEs) and non HPEs (e.g. PhDs) and different roles (e.g. teacher, administrator) completed the survey. Attitudes toward evidence-informed HPE were generally favorable. Several barriers preclude participants from engaging in evidence-informed approaches to health professions education (HPE). Discussion: This study provides preliminary evidence on the attitudes toward and perceived barriers and supports of research use in HPE from different groups of HP educators, clinicians, and administrators. The findings for each of the three domains require additional exploration using qualitative methodologies. Conclusion: Targeted interventions designed to increase the uptake of research in HPE should consider different stakeholder groups' perceptions regarding these approaches, current vs. best practices, and factors that may impede evidence-informed approaches.

Attributes of evidence-based occupational therapists in stroke rehabilitation.

BACKGROUND.: A better understanding of the features characterizing expert evidence-based occupational therapists in stroke rehabilitation is needed to inform the design of educational and knowledge translation interventions aimed at addressing research-practice gaps. PURPOSE.: The study aimed to identify the attributes of evidence-based occupational therapy stroke rehabilitation experts from the perspective of their peers. METHOD.: Forty-six occupational therapy clinicians and managers completed an online questionnaire asking them to nominate "outstanding" and "expert evidence-based" occupational therapists in stroke rehabilitation and to explain their choices. A thematic analysis of respondents' statements was conducted. FINDINGS.: Both outstanding and expert evidence-based occupational therapists were perceived to be motivated self-learners; to have extensive knowledge, skills, and experience; to act as scholarly practitioners; to achieve superior client outcomes; and to work in specialized settings. IMPLICATIONS.: The development of future strategies supporting occupational therapy students and clinicians to become lifelong learners should take into account key attributes of expertise, such as motivation for continuous learning and professional development.
