Switzerland already suffers from the long-predicted shortage of physicians. Moreover, the latter often face long and meandering postgraduate training. At the beginning of their career, most doctors work on internal medicine hospital wards, even though their future may just as well lie in an outpatient or inpatient setting, in general internal medicine or in other disciplines. To help these physicians identify and clarify their hospital trajectory at an early stage, thus optimizing training pathways, the Medicine Department of the CHUV set up its Housestaff. Using a mentorship system and clearly defining a training track (outpatient practice, hospital, academic, or transition), it supports candidates, in close partnership with other departments, regional hospitals and networks, in particular ambulatory ones.
