We founded the Partners HealthCare Center for Integrated Healthcare Data Research to build a data infrastructure that hosts and links a variety of long-term outcome data sources to electronic health records (EHR) from Partners Healthcare System (PHS) and to make them available for clinical effectiveness research. PHS researchers and their collaborators can therefore access the data through a user-friendly interface with self-service analytics infrastructure. Our goal is to bridge high-quality data with clinicians and researchers for timely and high-impact scientific discovery.
