Patient Data: Property, Privacy & the Public Interest

Changes in technology sometimes raise important public policy choices and require that we clarify key values and reexamine legal concepts. Such is the case with the development of electronic medical records (EMRs), which facilitate obtaining patient data from provider and insurer records. EMRs expand our ability to tap patient data and thereby create great potential benefits as well as risks. This new technology requires that we clarify the ambiguous property interests in patient data. How the law defines ownership of patient data will shape whether its benefits can be developed and also affects patient confidentiality. EMRs make it feasible to collect aggregate patient data that can be used to vastly improve medical knowledge, patient safety and public health. Researchers have long used patient data from clinical trials to evaluate the benefits and risks of drugs and medical therapy, compare their relative effectiveness, and analyze health care cost and quality.
