 Data collected during the assessment will include both binary variables for the presence of the aforementioned physical exam findings as well as to categorize the severity of each finding mild, moderate, severe. Clinical definitions for these categories will be defined ahead of time. In addition, a short questionnaire will be distributed to all of the subjects and patient study subjects. The questionnaire will ask subjects about their comfort in performing various aspects of the physical exam, their use of handheld ultrasound devices, as well as their experiences teaching medical students and residents the physical exam. Patient study subjects will answer a questionnaire about their attitude towards being examined by a physician using a handheld ultrasound device.
