In defence of teaching point-of-care ultrasound in undergraduate medical education

The Current Situation of Musculoskeletal Ultrasound Education: A Systematic Literature Review

As a radiation-free and dynamic imaging tool, musculoskeletal ultrasound improves diagnostic and therapeutic safety. With its growing application, the demand for training opportunities rises rapidly. Therefore, this work was aimed at mapping the current state of musculoskeletal ultrasonography education. A systematic literature search was conducted in January 2022 in the medical databases Embase, PubMed and Google Scholar. By use of specifically selected keywords, matching publications were filtered; then abstracts were screened independently by two authors and the inclusion of each publication was checked against pre-defined criteria according to the PICO (Population, Intervention, Comparator, Outcomes) scheme. Full-text versions of included publications were reviewed, and relevant information was extracted. Finally, 67 publications were included. Our results revealed a wide variety of course concepts and programs that have been implemented in different disciplines. Musculoskeletal ultrasonography training especially addresses residents in rheumatology, radiology and physical medicine and rehabilitation. International institutions, such as the European League Against Rheumatism and the Pan-American League of Associations for Rheumatology, have suggested guidelines and curricula to promote standardized ultrasound training. The development of alternative teaching methods incorporating e-learning, peer teaching and distance learning on mobile ultrasound devices and the determination of international guidelines could facilitate overcoming the remaining obstacles still to be passed. In conclusion, it can be stated that there is a broad consensus that standardized musculoskeletal ultrasound curricula would improve training and facilitate the implementation of new training programs.

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.
