Diarrhea in the Returning Traveler: A Simulation Case for Medical Students to Learn About Global Health

As global travel becomes more prevalent, medical students may be asked to care for patients with unforeseen exposures. We developed a simulation where clerkship medical students interviewed and examined a patient with recent travel who presented with bloody diarrhea and abdominal pain and was diagnosed with amebic colitis. The students had the opportunity to develop a differential diagnosis and discuss the workup of the patient.

We divided students into two groups. Each group took a turn participating in the simulation while the other group observed. Students were expected to interview and examine the patient as well as treat any urgent findings and develop a differential diagnosis. After each simulation, we reconvened with both groups for a faculty-led debriefing session to discuss the learning objectives, including approaches to caring for a patient with diarrhea and the differential diagnosis and workup of bloody diarrhea.

To date, five different groups of six to 12 students have completed this simulation. The module has been well received, and 100% of survey respondents have agreed that after completing the activity, they had a better understanding of how to approach a recent traveler with diarrhea and abdominal pain.

While most medical students will not travel abroad for traditional global health experiences, many will encounter patients with recent travel or immigration and must therefore be prepared to treat diseases typically categorized as global health. We developed this simulation and successfully incorporated workup of a returning traveler into the medical school curriculum for clerkship students.
