 Randomization and Curricular Training The 40 participating residents will be randomized to either the control or intervention group by having them blindly pick small pieces of paper with numbers out of a paper bag. All residents will participate in a 2 hour physical exam education session led by senior internal medicine faculty. Those randomized to the ultrasound group will also attend a 2 hour pocket-ultrasound training session which will be run by a BWH faculty radiologist and a BWH faculty echocardiographer. Following this training session, each of the 20 residents will be given a pocket-sized ultrasound device which they will be able to use as an adjunct to their physical exam while in clinic or on inpatient wards. Because the resident physicians are not trained ultrasound radiologists, these ultrasound studies will be informal and the results will not become part of any patients medical record. Participants in the control arm of the study will not receive pocket-sized ultrasound devices nor will they receive training on how to use the machines.
