Some rotations during clinical education are characterized by a high number
of hours spent per week in the hospital because students participate in a
hospital on-call system, i.e. hours beyond usual working hours, e.g. at nig
ht. However, students complain about spending too many hours in the hospita
l on non-instructive activities. This study was undertaken to investigate d
ifferences among rotations in time spent in hospital, in on-call hours, in
self-study and in noninstructive activities and to investigate the relation
ship between time spent on the various activities and the overall effective
ness as perceived by students. A questionnaire was administered to students
at the end of various clinical rotations. Rotations differ considerably in
time spent in hospital, on call (i.e. beyond usual working hours), on self
-study and on non-instructive activities. In some rotations students report
spending on average 18-20% of their time in the hospital on non-instructiv
e activities. Furthermore, the numbers of hours spent in hospital do not co
rrelate with the overall effectiveness as perceived by students, unless the
numbers of hours spent in non-instructive activities are taken into accoun
t. The effectiveness of a rotation does not automatically improve if studen
ts spend more hours in hospital. The number of hours spent on non-instructi
ve activities should be reduced in some rotations and should be kept as low
as possible. Further research is needed to find out which activities are p
erceived as noninstructive.
