Virtual Versus In-Person Head and Neck Physical Examination Training in Medical Students: A Pilot Assessment.

OBJECTIVE: To compare the effect of virtual and in-person head and neck physical examination training events on medical student confidence in performing examination maneuvers and seeking mentorship from otolaryngology faculty and residents. METHODS: Training events were held with first-year medical student volunteers in 2020 (in-person) and 2021 (virtual). Participants in both cohorts were given didactics on head and neck cancer, trained to perform a head and neck physical examination, and demonstrated their clinical skills to otolaryngology faculty and residents. Pre- and post-training surveys were utilized to assess the following outcomes: participant head and neck cancer knowledge, confidence in performing examination maneuvers, and confidence in seeking mentorship in otolaryngology. Differences in outcomes between training settings were assessed by comparing participant survey responses pre- and post- training. RESULTS: Both in-person and virtual training modalities improved participant confidence in performing the physical examination. There was no significant difference in the degree of improvement between training types. In-person training significantly increased participant confidence in seeking mentorship from otolaryngology faculty and residents (P = .003), while virtual training did not (P = .194). CONCLUSION: Virtual training modalities are feasible methods of teaching the head and neck physical examination. Instruction through a video conferencing platform has the potential to be incorporated into traditional in-person medical education in a permanent fashion. This pilot study can inform future studies directly comparing in-person and virtual physical examination training modalities.

The Role of Educational Podcast Use Among Otolaryngology Residents.

OBJECTIVE: Medical podcasts are becoming increasingly available; however, it is unclear how these new resources are being used by trainees or whether they influence clinical practice. This study explores the preferences and experiences of otolaryngology residents with otolaryngology-specific podcasts, and the impact of these podcasts on resident education and clinical practice. METHODS: An 18-question survey was distributed anonymously to a representative junior (up to post-graduate year 3) and senior (post-graduate year 4 or greater) otolaryngology residents at most programs across the US. Along with demographic information, the survey was designed to explore the preferences of educational materials, podcast listening habits and motivations, and influence of podcasts on medical practice. Descriptive statistics and student t-tests were used to analyze the results. RESULTS: The survey was distributed to 198 current otolaryngology residents representing 94% of eligible residency programs and was completed by 73 residents (37% response rate). Nearly 3-quarters of respondents reported previous use of otolaryngology podcasts, among which 83% listen at least monthly. Over half of residents changed their overall clinical (53%) and consult (51%) practice based on podcast use. Residents rank-ordered listening to podcasts last among traditional options for asynchronous learning, including reading textbooks and watching online videos. CONCLUSIONS: While other asynchronous learning tools remain popular, most residents responding to this survey use podcasts and report that podcasts influence their clinical practice. This study reveals how podcasts are currently used as a supplement to formal otolaryngology education. Results from the survey may inform how medical podcasts could be implemented into resident education in the future.

In Vitro models for thrombogenicity testing of blood-recirculating medical devices.

INTRODUCTION: Blood-recirculating medical devices, such as mechanical circulatory support (MCS), extracorporeal membrane oxygenators (ECMO), and hemodialyzers, are commonly used to treat or improve quality of life in patients with cardiac, pulmonary, and renal failure, respectively. As part of their regulatory approval, guidelines for thrombosis evaluation in pre-clinical development have been established. In vitro testing evaluates a device's potential to produce thrombosis markers in static and dynamic flow loops. AREAS COVERED: This review focuses on in vitro static and dynamic models to assess thrombosis in blood-recirculating medical devices. A summary of key devices is followed by a review of molecular markers of contact activation. Current thrombosis testing guidance documents, ISO 10993-4, ASTM F-2888, and F-2382 will be discussed, followed by analysis of their application to in vitro testing models. EXPERT OPINION: In general, researchers have favored in vivo models to thoroughly evaluate thrombosis, limiting in vitro evaluation to hemolysis. In vitro studies are not standardized and it is often difficult to compare studies on similar devices. As blood-recirculating devices have advanced to include wearable and implantable artificial organs, expanded guidelines standardizing in vitro testing are needed to identify the thrombotic potential without excessive use of in vivo resources during pre-clinical development.
