As a healthcare data scientist, your duties are to develop tools for collecting or extracting data maintained by hospitals, healthcare, providers, or federal and state agencies. You collect and analyze information, such as medical records, insurance claims, or billing information and then identify patterns or trends in the data and recommend ways to use that information to improve industry efficiency and performance. Healthcare data scientists develop forecasting and modeling programs designed to form analyses of medical records or other forms of healthcare information. Sometimes you use the models themselves while in other instances you develop these models so that healthcare workers can use them in their daily practices.
