USCE can be broadly divided into hands-on and hands-off experiences. Observerships – rotations during which a student observes a doctor doing their work but is not allowed to participate – are a clear example of hands-off experience. By definition, clerkships, clinical electives, or clinical rotations are all names for essentially the same thing – rotations during which you participate in the patient care process.
It is easy to imagine why many residency programs prefer students with hands-on clinical experience within the States. They want a resident who is able to manage the day-to-day work of the program, and having prior encounters with the medical system in the US is a big help in that sense.
