Purpose. To assess the extent to which house officers know the social
histories of thier hospital patients, and to examine the factors that
influence social history knowledge. Method. In October-November 1992,
all 31 internal medicine housestaff rotating on the hospital inpatient
services at the University of Kentucky A. B. Chandler Medical Center
completed questionnaires regarding the social histories of up to three
of their patients. Responses were analyzed using simultaneous multipl
e linear regression analysis. Results. Standard questions about social
history were answered correctly only 29% of the time (two of seven it
ems). The overall knowledge of patients' social histories was signific
antly less for supervising residents than for interns (p = .03) and, i
ndependently, for housestaff with greater patient loads (p = .04). Kno
wledge of a patient's social history was not related to the particular
inpatient service, time the patient was admitted, or other characteri
stics of the patients or residents. Conclusion. The internal medicine
residents' knowledge of their hospital patients' social histories was
limited, particularly when the residents had relatively heavy patient
loads or supervisory roles in patient care. The data suggest that pati
ents' social histories may have been underemphasized during the reside
nts' training.
