Virtual Supervision of Third Year Medical Students Using Handheld POCUS Devices and Cloud-based Image Archiving Provides Opportunity for Feedback and Skill Improvement.

Background : Feedback on Point of Care Ultrasound (POCUS) skills is essential for skill development. Providing feedback can be difficult in a large province with several distributed medical education sites. Use of handheld POCUS devices and a cloud-based image archiving enables virtual supervision. We evaluated the quality of uploaded images as well as feedback provided to students. Methods: Volunteer third year students were given access to handheld POCUS devices at various training sites. Students were encouraged to upload educational POCUS scans to their accounts where they would then receive feedback from faculty. Subsequently, images that met inclusion criteria were randomized and reviewed by a blinded expert using a global rating scale. Feedback was also analyzed. Finally, students completed a questionnaire on their technology-enhanced POCUS learning experience. Results: An independent-sampled t-test comparing mean ratings for initial images submitted prior to any feedback with those submitted after three rounds of feedback showed significant effect on image scores (2.60 vs 3.50, p = .040, d = .93). Feedback included 4 performance domains (indications, image generation, interpretation, and integration). Students found the technology easy to use and felt feedback was tailored to their learning needs. Conclusions: We observed that virtual feedback provided to medical students through a cloud-based work platform can be effective for enhancing POCUS skills.

Evaluating Best Methods for Crisis Resource Management Education: Didactic Teaching or Noncontextual Active Learning.

INTRODUCTION: Health care training traditionally focuses on medical knowledge; however, this is not the only component of successful patient management. Nontechnical skills, such as crisis resource management (CRM), have significant impact on patient care. This study examines whether there is a difference in CRM skills taught by traditional lecture in comparison with low-fidelity simulation consisting of noncontextual learning through team problem-solving activities. METHODS: Two groups of multidisciplinary preclinical students were taught CRM through lecture or noncontextual active learning. Both groups were given a cardiopulmonary resuscitation simulation and clinical performance assessed by basic life support (BLS) checklist and CRM skills by Ottawa Global Rating Scale. The groups were reassessed at 4 months. A third group, who received no CRM education, served as a control group. RESULTS: The mean BLS scores after CRM education were 18.9 and 24.9 with mean Ottawa Global Rating Scale (GRS) scores of 22.4 and 29.1 in the didactic teaching and noncontextual groups, respectively. The difference between intervention groups was significant for BLS (P = 0.02) and Ottawa GRS (P = 0.03) score. At 4-month follow-up, there was no statistically significant difference in BLS (P = 1.0) or Ottawa GRS score (P = 0.55) between intervention groups. In comparison with the control group, there was a marginally significant difference in Ottawa GRS score (P = 0.06) at 4-month follow-up. CONCLUSIONS: Noncontextual active learning of CRM using low-fidelity simulation results in improved CRM performance in comparison with didactic teaching. The benefits of CRM education do not seem to be sustained after one education session, suggesting the need for continued education and practice of skills to improve retention.
