Background and Objectives: Little is known about the relationship between t
he length of a family medicine clerkship and its educational outcomes. Afte
r our family medicine clerkship time decreased from 6 weeks to 4 weeks in J
uly 1997, we studied how this change in clerkship length affected education
al outcomes. Methods: Educational outcomes for the 2-year periods before an
d after the change were examined and compared whenever possible. Outcome me
asurements included student ratings of different aspects of the clerkship a
nd student performance on clerkship examinations. Results: Students' exposu
re to common clinical problems was unaffected by the change. For the 4-week
clerkship, there was a slight increase in student ratings of the adequacy
of number of patients seen, the opportunity to follow-up with patients, the
ability to develop health promotion plans, and overall satisfaction. Becau
se the combinations of examinations used differed each year; student perfor
mance on clerkship examinations could not be directly compared. Conclusions
: Educational outcomes of the 4-week clerkship were similar to the 6-week c
lerkship. A few, key outcomes improved. Various curricular and structural c
hanges instituted for the 4-week clerkship contributed to the stability in
outcomes. Reports from other medical schools may give additional insight in
to understanding this relationship.
