They treat an incredibly wide variety of medical conditions, whether they be acute or chronic, common or rare, complex or straightforward.

The competencies trained in the internal medicine rotation also have a lot of crossover with other specialties.

When to Place the Internal Medicine Rotation

Where you place the internal medicine rotation depends on your interest in pursuing it as a specialty and when you plan to take the Step 2 CK exam. If you want to pursue internal medicine for residency, it’s most strategic to place this rotation second or third out of the total of four quarters of the year. Placing it first, when you’re just getting the hang of your third year clerkships, may not be the best time for you to impress your seniors and attendings. Not placing it last ensures you’re able to get enough references for applying to away rotations and residencies.
