Objective: To compare amounts of in-hospital time use by PGY1 resident
s during rotations in emergency medicine (EM), internal medicine (IM),
and surgery. This article reports the general study methodology and f
ocuses on the educational aspects of residency time use. Methods: A cr
oss-sectional, observational study of the activities of Ehl PGY1 resid
ents was performed while the residents were on duty during the 3 speci
alty rotations. The activities were recorded by an observer using a lo
g with predetermined categories for clinical/service, educational, and
personal areas. A time-blocked, convenience sample of resident shifts
was observed for each service rotation. The sample was proportional D
o the total number of hours for which a PGY1 resident was expected to
be in the hospital during a rotation on that service. No attempt was m
ade to sample the same resident at all time periods or on all rotation
s. Results: Twelve PGY1 residents were observed for a total of 166 hou
rs on surgery, 156 hours on IM, and 120 hours on EM. These hourly amou
nts were representative of a typical 2-week span of service on each ro
tation for the residents. On average, the residents spent 57% of their
time on clinical or service-oriented activities, 24% on educational a
ctivities, and 19% on personal activities. The proportions of time dev
oted to the 3 major areas were similar for the 3 rotations. In all 3 r
otations, the largest proportion of time was spent on patient-focused
education (81% to 92% of total educational time). Only 2% to 11% of ed
ucational time was devoted to self-education. Within the patient-focus
ed education category, proportionately less resident time with faculty
occurred on the surgery rotation than on the EM and IM rotations (18%
vs 30% and 27%, respectively). Conclusion: The general breakdowns of
clinical/service, educational, and personal time use by PGY1 residents
are proportionately similar for the 3 service rotations. Patient-focu
sed education is the primary mode of education for all services. In-ho
spital, self-education time is limited. Clinical teaching is largely b
y nonfaculty. The educational implications of these findings are discu
ssed.
