Abstract
At the beginning of the 21st century, we are at the dawn of a possibly unprecedented era of scientific discovery and promise. Emerging technologies, including information and communication technologies, genomics, microelectromechanical systems, robotics, sensors, and nanotechnologies, provide enormous opportunities for population health improvement. Population health technology refers to the application of an emerging technology to improve the health of populations. Emerging technologies present an opportunity for addressing global health challenges-in both developed and developing countries. Health issues ripe for the application of new technologies include disease surveillance and control, environmental monitoring and pollution prevention, food safety, health behavior change, self-care, population screening, and chronic disease and injury prevention and control. If appropriately applied, population health technologies may greatly enhance existing health intervention models. However, potential adverse consequences could arise related to privacy, confidentiality, and security; quality and effectiveness; sustainability; and the technology divide. To ensure the optimal development and diffusion of population health technologies will require balancing these risks and benefits while simultaneously adopting new mechanisms of public and private support for research and development in this potentially important new domain of public health.
