Access to high-quality, real-world data gives health care providers insights for effectively managing chronic diseases, and lays the foundation for training artificial intelligence, says Oscar Marroquin, chief health care data and analytics officer at University of Pittsburgh Medical Center. IT staff, data engineers, clinical analysts and business intelligence specialists maintain UPMC's data warehouse, which serves as the basis for self-service tools such as predictive and statistical analytics and artificial intelligence models for health care providers and business administrators, Marroquin said.
