The Boston Globe reported the launch of a new website that allows Massachusetts residents to compare the cost and quality of care at different hospitals in the state.  Patients now have access to previously confidential information that they can use to make informed decisions about the medical care they seek.  Consumers can compare, for example, patient satisfaction data and safety measures at different hospitals.  With this tool, residents of the state can make more informed decisions about their care.  As information becomes public about disparities, providers may even attempt to fill gaps in quality and cost of service.  A healthcare system that promotes transparency also promotes public health.
