Tackling the void: the importance of addressing absences in the field of health professions education research.

Many processes and practices in the field of health professions education have been based more on tradition and assumption than on evidence and theory. As the field matures, researchers are increasingly seeking evidence to support various teaching and assessment methods. However, there is a tendency to focus on a limited set of topics, leaving other areas under-examined and limiting our understanding of the field. By explicitly examining areas that are undescribed, i.e. absences in the literature, researchers and scholars have the potential to enrich our practice and our field's understanding of what counts as legitimate research. Using the theoretical framework of Bourdieu's concept of field, we conducted an instrumental case study of three published research projects that each had a finding of absence. We examined each case individually, and then analyzed across cases. Our dataset included published papers, peer-review feedback, and reflective notes. Each of the cases interrogated a different form of absence: absence of content, absence of research, and absence of evidence. While the typology suggests that each absence was different, there were similarities across cases in terms of challenges in 'proving' the reality of the absence and some disbelief or discomfort with accepting the findings as rigorous and/or legitimate. Absence research has potential to add to our theoretical and methodological approaches to the field. This type of research is potentially an exciting and productive new way for scholars to shed light on aspects of health professions education that have received limited attention to date.

Dismantling the master's house: new ways of knowing for equity and social justice in health professions education.

Health professions education (HPE) is built on a structural foundation of modernity based on Eurocentric epistemologies. This foundation privileges certain forms of evidence and ways of knowing and is implicated in how dominant models of HPE curricula and healthcare practice position concepts of knowledge, equity, and social justice. This invited perspectives paper frames this contemporary HPE as the "Master's House", utilizing a term referenced from the writings of Audre Lorde. It examines the theoretical underpinnings of the "Master's House" through the frame of Quijano's concept of the Colonial Matrix of Power (employing examples of coloniality, race, and sex/gender). It concludes by exploring possibilities for how these Eurocentric structures may be dismantled, with reflection and discussion on the implications and opportunities of this work in praxis.

A Dialogic Approach to Teaching Person-Centered Care in Graduate Medical Education.

BACKGROUND: Training future physicians to provide compassionate, equitable, person-centered care remains a challenge for medical educators. Dialogues offer an opportunity to extend person-centered education into clinical care. In contrast to discussions, dialogues encourage the sharing of authority, expertise, and perspectives to promote new ways of understanding oneself and the world. The best methods for implementing dialogic teaching in graduate medical education have not been identified. OBJECTIVE: We developed and implemented a co-constructed faculty development program to promote dialogic teaching and learning in graduate medical education. METHODS: Beginning in April 2017, we co-constructed, with a pilot working group (PWG) of physician teachers, ways to prepare for and implement dialogic teaching in clinical settings. We kept detailed implementation notes and interviewed PWG members. Data were iteratively co-analyzed using a qualitative description approach within a constructivist paradigm. Ongoing analysis informed iterative changes to the faculty development program and dialogic education model. Patient and learner advisers provided practical guidance. RESULTS: The concepts and practice of dialogic teaching resonated with PWG members. However, they indicated that dialogic teaching was easier to learn about than to implement, citing insufficient time, lack of space, and other structural issues as barriers. Patient and learner advisers provided insights that deepened design, implementation, and eventual evaluation of the education model by sharing experiences related to person-centered care. CONCLUSIONS: While PWG members found that the faculty development program supported the implementation of dialogic teaching, successfully enabling this approach requires expertise, willingness, and support to teach knowledge and skills not traditionally included in medical curricula.

Stethoscope of the 21st century: dominant discourses of ultrasound in medical education.

CONTEXT: In recent years, point-of-care ultrasound (POCUS) has become a widely used clinical tool in a number of clinical specialties. In response, POCUS has been incorporated into medical curricula across the learning continuum, bolstered by enthusiastic appraisals of the technology's benefits for learners, clinicians and patients. In this project, we have sought to identify and understand the effects of dominant discourses influencing the integration of POCUS into medical education. METHODS: We conducted a Foucauldian critical discourse analysis (CDA) to identify and analyse discourses that legitimise and privilege the use of POCUS in medical education. We assembled an archive of 473 texts published between 1980 and 2017. Each article in the archive was analysed to identify frequently occurring truth statements (expressing concepts whose truths are unquestioned within particular discourses) that we used to characterise the major discourses that construct representations of POCUS in medical education. RESULTS: We identified three dominant discourses: (i) a visuo-centric discourse prioritising the visual information as truth over other clinical data; (ii) a utilitarian discourse emphasising improvements in patient care; and (iii) a modernist discourse highlighting the current and future needs of clinicians in our technological world. These discourses overlap and converge; the core discursive effect makes the further elevation of POCUS in medical education, and the resulting attenuation of other curricular priorities, appear inevitable. CONCLUSIONS: The three dominant discourses identified in this paper engender ideal conditions for the proliferation of POCUS in medical education through curricular guidelines, surveys of adherence to these guidelines and authoritative position statements. By identifying and analysing these dominant discourses, we can ask questions that do not take for granted the assumed truths underpinning the discourses, highlight potential pitfalls of proposed curricular changes and ensure these changes truly improve medical education.

Ultrasound in undergraduate medical education: a systematic and critical review.

CONTEXT: The use of point-of-care ultrasound (POCUS) in clinical care is growing rapidly and advocates have recently proposed the integration of ultrasound into undergraduate medical education (UME). The evidentiary basis for this integration has not been evaluated critically or systematically. OBJECTIVES: We conducted a critical and systematic review framed by the rationales enumerated in academic publications by advocates of ultrasound in UME. METHODS: This research was conducted in two phases. First, the dominant discursive rationales for the integration of ultrasound in UME were identified from an archive of 403 academic publications using techniques from Foucauldian critical discourse analysis (CDA). We then sought empirical evidence in support of these rationales, using a critical synthesis methodology also adapted from CDA. RESULTS: We identified four dominant discursive rationales with different levels of evidentiary support. The use of ultrasound was not demonstrated to improve students' understanding of anatomy. The benefit of ultrasound in teaching physical examination was inconsistent and rests on minimal evidence. With POCUS, students' diagnostic accuracy was improved for certain pathologies, but findings were inconsistent for others. Finally, the rationale that ultrasound training in UME will improve the quality of patient care was difficult to evaluate. CONCLUSIONS: Our analysis has shown that the frequently repeated rationales for the integration of ultrasound in UME are not supported by a sufficient base of empirical research. The repetition of these dominant discursive rationales in academic publications legitimises them and may preclude further primary research. As the value of clinical ultrasound use by medical students remains unproven, educators must consider whether the associated financial and temporal costs are justified or whether more research is required.

Oxidative injury to blood vessels and glia of the pre-laminar optic nerve head in human glaucoma.

Glaucoma is a leading cause of irreversible world blindness. Oxidative damage and vascular injury have been implicated in the pathogenesis of this disease. The purpose of this study was to determine in human primary open angle glaucoma whether oxidative injury occurs in pre-laminar optic nerve blood vessels and glial cells. Following IRB approval, sections from post-mortem primary open angle glaucoma eyes (n=5) with mean age of 77 +/- 9 yrs (+/-SD) were compared to normal control eyes (n=4) with mean age 70 +/- 9 yrs (Eye Bank of Canada). Immunostaining with nitrotyrosine, a footprint for peroxynitrite-mediated injury, was performed and sections were double-labeled with markers for vascular endothelial cells, perivascular smooth muscle cells, and astrocytes with CD34, smooth muscle actin (SMA), and glial fibrillary acidic protein (GFAP), respectively. Immunostaining was captured in a masked fashion using confocal microscopy, and defined regions of interest for blood vessels and glial tissue. Intensity measurements of supra-threshold area in pixels as percent of the total number of pixels were calculated using ImageJ (NIH) and compared using two-tailed Mann-Whitney nonparametric tests between glaucoma and control groups. Colocalization coefficients with cell-specific markers were determined and compared with random coefficients of correlation. Increased nitrotyrosine immunoreactivity was observed in pre-laminar optic nerve head blood vessels of primary open angle glaucoma eyes compared to controls and this difference was statistically significant (1.35 +/- 1.11% [+/-SD] vs. 0.01 +/- 0.01%, P=0.016). NT-immunoreactivity was also increased in the glial tissue surrounding the pre-laminar optic nerve head in the glaucoma group and compared to controls, and this difference was statistically significant (18.37 +/-12.80% vs. 0.08 +/- 0.04%, P=0.016). Colocalization studies demonstrated nitrotyrosine staining in vascular endothelial and smooth muscle cells, in addition to astrocytes. Correlation coefficients for CD34, SMA, and GFAP were 0.37, 0.52, and 0.64, respectively. Oxidative injury is present in blood vessels and astrocytes in the pre-laminar optic nerve head in human primary open angle glaucoma. Peroxynitrite-mediated oxidative injury, whether primary or secondary, may contribute to the pathobiology of glaucoma disease.
