How do public health, epidemiology, and population health intersect at the local level to impact the health outcomes of patients? Remle Newton-Dame of New York City Health + Hospitals joins us this week to discuss her work at "The Data Core" in the Office of Population Health, a team responsible for providing innovative analytics to transform care delivery. The Data Core touches risk targeting, access to care, depression, care management, outreach to the uninsured, and support of incarcerated populations. Their mission is to use data and technology to create actionable knowledge at the program, site, and system levels. Technologies like data visualization packages and electronic medical records enable healthcare professionals, as well as individual patients, to understand large amounts of information about their exact health questions. Remle expands on these ideas, and more, as she discusses technology's role in collecting, interpreting, and acting on health data.
