Objective: To evaluate the effect of a three-hour training session in formu
lating questions and searching databases.
Design: A randomised controlled trial and before and after study, with blin
ded outcome assessment.
Setting: Oxford University Medical School, first clinical year.
Subjects: Altogether 108 medical students were randomly assigned to an expe
rimental group (54) or a control group (54), and all were given the task of
searching for evidence around an ulcer related problem or a cardiac proble
m. Students in the experimental group were randomly allocated to research o
ne of the two problems before training and the remaining problem afterwards
. Control students received no training and were randomly allocated to sear
ch for evidence around either of these problems.
Main outcome measures: Searching performance; the quality of evidence retri
eved; student satisfaction.
Results: Training improved the students' search performance and the quality
of evidence retrieved. Students' satisfaction with the training was high.
Conclusions: A three-hour interactive training session improved the student
s' ability to search databases and retrieve evidence and was well received
by the students.
