Experimental Design
A parallel, unblinded, randomized controlled trial. Participants will include third- and fourth-year medical students, internal medicine residents, and emergency medicine residents meeting the below criteria.
Inclusion Criteria
• Age greater than or equal to 18
• Ability to access Twitter via personal device
• Active status as a third- or fourth-year medical student, or resident physician
Exclusion Criteria
• Formal training in point-of-care ultrasound outside of usual graduate medical education activities (i.e. certificate or fellowship in point-of-care ultrasound, previous work as ultrasound technician, etc.)
• Already following 5 or more accounts that consistently post content related to point-of-care ultrasound
• Already following more than 5 accounts listed in the intervention arm.
• Engaged, or planning to engage, in POCUS education outside of typical medical education curricula during the study period
Briefly, the intervention will consist of following at least 10 accounts that post consistent content in POCUS image interpretation, while the control arm will consist of following at least 10 medical journal accounts. Both arms will be given the recommendation to spend at least 2 hours per week on Twitter.
The study duration will be 12 weeks, with interval logs reported throughout. The logs will be sent out via email every three to four weeks and query how often participants are utilizing Twitter, as well as a few additional questions (to be developed). Participants will be recommended to obtain their Twitter use via the automatic app use logging on iPhones and most android devices.
At the conclusion of the study, participants will retake the POCUS image interpretation assessment, as well as a post-study survey.
The study will be unblinded due to feasibility.
