There is little debate about the importance of ethics in health care, and clearly defined rules, regulations, and oaths help ensure patients’ trust in the care they receive. However, standards are not as well established for the data professions within health care, even though the responsibility to treat patients in an ethical way extends to the data collected about them. Increasingly, data scientists, analysts, and engineers are becoming fiduciarily responsible for patient safety, treatment, and outcomes, and will require training and tools to meet this responsibility. Healthcare privacy is a central ethical concern involving the use of big data in healthcare, with vast amounts of personal information widely accessible electronically. In this episode, guest Eugene Day sits down with TDS to discuss his work in the healthcare data field, as well as some research Seattle Children’s Hospital, has done surrounding biases and ethicality within healthcare data.
