Conscientious sign-out between medical interns is important for the co
ntinuity of care of hospitalized patients, We developed a standardized
sign-out card that prompted the intern going off duty to transmit pat
ient care information to the intern on call, The card was tested in a
prospective, randomized, controlled trial in which one group of intern
s used the card, and another group did not, Any instance of poor sign-
out was reported on a questionnaire completed by the intern who had be
en on call the previous night, The group using the sign-out cards repo
rted poor sign-out on 8 nights (5.8% of questionnaires), and the contr
ol group reported it on 17 nights (14.9% of questionnaires, p = .016),
The card was time-effective and inexpensive, resulted in more complet
e data recording, and possibly decreased the morbidity associated with
poor sign-out.
