Optum Labs Data Warehouse

What is Optum Labs?

Optum Labs is a collaborative research and innovation center with its core linked data assets in the Optum Labs Data Warehouse (OLDW). University of Maryland Baltimore joined the Optum Labs collaborative as a partner in 2024. The University of Maryland Institute for Health Computing (UM-IHC) leads this important relationship.

Optum Labs Data Warehouse (OLDW) is a comprehensive, nationwide real-world database that contains de-identified, longitudinal health information on enrollees and patients, representing a mixture of ages and geographical regions across the United States. The claims data in OLDW includes medical and pharmacy claims, laboratory results and enrollment records for over 200M commercial and Medicare Advantage enrollees. The electronic health record (EHR)-derived data in OLDW includes a subset of EHR data sourced from different health systems and practices across the United States that has been normalized and standardized into a single database. Additional data linkages may be feasible, as long as there is no risk of data re-identification.

All data are kept in a secure environment and in accordance with the Health Insurance Portability and Accountability Act (HIPAA) regulations; no personally identifiable information is shared.

Why Optum Labs?

In addition to gaining access to one of the largest linked patient databases available in the U.S., researchers are able to leverage a network of world-class thought leaders from across Optum Labs partners. OLDW data has been used for a wide range of impactful research studies.

Premier Healthcare Database

What is the Premier Healthcare Database (PHD)?

PHD is a large, comprehensive U.S.-based healthcare data repository maintained by Premier Inc. It is widely used for real-world evidence research and healthcare analytics. The University of Maryland Institute for Health Computing (UM-IHC) has licensed Premier data for use in approved UMB research studies.

Why PHD?

• Covers >1,400 hospitals and ambulatory surgical centers

• Data types included:

  • Administrative data (e.g., billing, coding)

  • Clinical data (e.g., diagnoses, procedures, medications)

  • Healthcare utilization (e.g., length of stay, readmissions)

  • Financial data (e.g., cost and charge information)

• Clean, well-defined data dictionary

• PHD hospitals cover highly geographically diverse areas across the U.S. and capture approximately one of every four U.S. hospital discharges

• Premier internally validates all data before release into the research database
