“We assist our research partners in developing successful study protocols and competitive grant submissions, as well as supporting study execution including data-only studies, by making high quality real-world data and analytics available.”
Andrew Williams, PhDAssociate Director, Informatics
There is a growing need for secondary use of regularly collected health care information in research to develop scientific evidence and assist providers, patients, and policy makers to make informed decisions about clinical effectiveness, comparative effectiveness, population health, and outcomes.
Tufts CTSI provides assistance to its many research partners in developing successful study protocols and competitive grant submissions, as well as supporting study execution. This support partly relies on the availability of real-world data in a research data warehouse (RDW). Our RDW for research, Tufts Medical Center (Tufts MC) Research Data Warehouse (TRDW), in Observational Medical Outcomes Partnership (OMOP) common data model (CDM), is developed, maintained, and continuously enhanced by Tufts CTSI’s development team in collaboration with Tufts MC Information Services.
TRDW data includes patient demographics on more than one million patients, lab values, procedure and diagnosis codes, observations, medications, visit, notes, and reports and is being continuously enhanced.
TRDW contains data from major Tufts MC Electronic Health Record (EHR) systems, including inpatient, outpatient, claims, tumor registry, and the state death registry.
Tufts CTSI collaborates with the OHDSI community at an international level to continue development of OMOP CDM.
- The OMOP Common Data Model allows for the systematic analysis of disparate observational databases.
- Data standardization increases the potential for collaborative research.
- Data from various sources are transformed into a common format and common representation.
- Standard analytic methods are applied to a common format for data quality, data characterization, safety surveillance, and other applications.
We continue to enhance the data warehouse and improve data quality to advance cohort discovery, recruitment planning, and to support retrospective and prospective clinical and translational research.

Who is eligible?
Most Tufts CTSI Informatics services are available to Tufts CTSI partners and collaborators. Tufts MC’s data is available to researchers outside of Tufts MC only with IRB approvals and other relevant agreements.
For fast and successful service:
- Please follow IRB guidelines in the HIPAA forms section and obtain necessary approvals or waivers.
- IRB approvals are not required for assessing feasibility of the study (cohort discovery).
- IRB approvals are required for any requests involving receipt of data, e.g., contact information, de-identified or limited dataset. Please have the approvals available when requesting services.
- If you are a Tufts MC investigator and plan to share data outside of Tufts MC, please contact Research Administration for guidance.
- You must have an established HIPAA-compliant system or have secure access to a HIPAA-compliant system to store extracted data. Please follow the IRB Confidentiality and Data Security Guidelines for Electronic Research data, available here.
If you plan on collecting data for the purpose of human subjects research, your project must be reviewed and approved by your IRB.
Tufts CTSI does not provide data storage for any exported datasets. You must have a plan to transfer and store any exported report or data, and ensure the system meets the HIPAA requirements. If you need assistance for storing large datasets we will be glad to refer you to appropriate resources.
