- All resident physicians rotating through study teams during the two 6 month periods of data collection will be included in the study if informed consent is granted. No resident physicians will be excluded on the basis of age, gender, ethnicity, race, or other demographic features. We anticipate enrolling a maximum of 70 resident physicians per site. This number may be significantly less due to the fact that certain residents may rotate through data collection study units more than once during the study period.
