Surgical and other disciplines have been noticing difficulties in recruiting junior staff for several years. In response to a decrease in interest within study courses, surgical associations recommend better supervision during undergraduate practical education as "clerkships" in order to increase the attractiveness of surgery. This clerkship has an initiation function, as students for the first time - albeit marginally - can act as physicians. The aim of this study was to investigate the impact of clerkships on the disciplinary orientations and preferences of undergraduates' perceptions of specialist training. Medical students of the Otto-von-Guericke University Medical School at Magdeburg were interviewed at 4 different time points in their clinical training (n = 373). The questionnaire included different dimensions on i) their choice of the subjects of clerkships and ii) on their clerkship experiences. Questions were subdivided into 5 basic topics, including 5 options to answer according to "Likert's scale" ranging from 1 to 5 ("completely true" to "does not apply at all"). Data were statistically analysed. Clerkships are an important component of medical studies. Undergraduate medical students deliberately use clerkships to get to know and to discriminate between medical disciplines they consider as possible choices for later specialisation. Their own assessment as well as reported experiences of specific clinics, departments or supervisors influence decision-making with regard to medical disciplines and locations/institutions for clerkships. The contents of the clerkships is expected to be closely related to the medical curricula. Students expect a detailed insight and practical, cross-departmental, interdisciplinary integration and collaboration in the medical discipline selected for clerkship. Clerkship experience in surgery affects the students' preference for surgical disciplines. They are a relevant predictor. High-quality teaching - an important part of practical undergraduate training (clerkship) is effective in fostering a subsequent surgical orientation. Preference for surgical specialisation can be strengthened during medical studies by preparing seminars and extended practical experiences during clerkship.
