Baylor Medicine

Baylor Medicine’s outpatient care database includes about 450,000 patients as of 2025. The data focuses on ambulatory and ancillary services — including labs, infusions and imaging — provided in Baylor College of Medicine-owned facilities in Houston, Texas.

Ambulatory care provided by Baylor faculty in affiliate hospitals and health systems (Texas Children’s Hospital, Baylor St. Lukes Medical Center and Ben Taub General Hospital) are not represented in Baylor Medicine data. Investigators should consider whether their research question involves outpatient care delivered in Baylor Medicine or Baylor-affiliated practices.

Note: Inpatient data from Baylor-affiliated hospitals is not included. Identifiable data, including free-text notes and test results, is available depending on the access method.

  • Baylor Medicine uses Epic for its EHR system, with data stored in two SQL-based databases:

    Epic Clarity

    • Built from real-time EHR data

    • Normalized model with 20,000 tables

    • Granular but highly redundant data that can have non-intuitive relationships

    • May be preferred for technically capable investigators

    Epic Caboodle

    • Built from Clarity using a dimensional model

    • 500 tables organized by domains such as vital signs, encounters, diagnoses, medications orders, procedures, laboratory results, clinical and imaging reports (not images) and flowsheets

    • Explore Baylor Medicine data with Epic SlicerDicer via Epic Hyperspace or MyApps (Baylor credentials required).

    • Provides summary statistics and limited trends; patient-level data is not available. Advanced analysis requires Clarity or Caboodle access.

Baylor St. Luke’s Medical Center (BSLMC) Data

Baylor St. Luke’s Medical Center (BSLMC) is an affiliate hospital of Baylor College of Medicine. It is a tertiary care hospital and clinic system that is part of CommonSpirit Health. Electronic health record data from BSLMC are available. These data include individuals hospitalized at BSLMC and those seen in BSLMC-affiliated outpatient clinics.

Patient data from the Texas Heart Institute, the Dan L Duncan Cancer Center and solid organ transplant services are housed within BSLMC records rather than Baylor Medicine, as these entities operate through BSLMC. Currently, the data are stored only in an Epic Clarity database, but efforts are underway to make a BSLMC Caboodle database available to investigators. Linkage between BSLMC and Baylor Medicine patient records is possible through a crosswalk file provided by the Office of Research IT.

  • Multi-institutional teams are encouraged, but due to data security policies, only investigators with Baylor credentials may directly access the data with appropriate approval.
