[A good care of students in their residency (PJ students)--a win-win-situation].

The provision of good mentors and education to medical students in their residency (PJ students) bears three essential advantages: 1) If the students feel themselves in good hands, they will co-operate effectively, thereby reducing the burden of the medical staff. 2) Contented students are potential advertisers for other interns, clinical trainees, medical students in residency and Ph.D. students. 3) Given the lack of doctors, providing students with good mentors and training is a valuable long-term strategy for the recruitment of doctors; in the event of later employment, former students in residency represent employees who are motivated, well trained, and familiar with hospital routine--a classical win-win situation.
