The goal of this study is to identify objective differences between primary care and traditional medicine residents in clinical performance, continuity of care and utilization of resources. Specifically, this retrospective study will analyze the database collected by CLIMACS, the computer system at Cornell Internal Medicine Associates (CIMA). This system is used for clinical and administrative purposes; it manages and tracks patient's information and demographics, appointment booking, clinical diagnosis, prescriptions and medications, laboratory and radiology test, and consults. In our study, we will analyze a subset of the CLIMACS database from previous years.
