Fred Hutch Cancer Center Patient Clinical Data for Research

Access to clinical data for Fred Hutch Cancer Center’s patient population is critical for research activities at Fred Hutch Cancer Center. This page outlines the clinical data systems at Fred Hutch Cancer Center that can be used for research.

Upcoming Opportunities

Recent changes have opened up new opportunities for Fred Hutch, but to benefit from these changes, the institution needs to adjust its approach to leveraging data. In spring 2022, FHCRC and SCCA merged to form Fred Hutch Cancer Center and Dr. Jeff Leek was hired as Chief Data Officer. The Fred Hutch data needs assessment, which ran from April 2022 to April 2023, identified clinical data access, data governance, clinical data analysis support, and clinical data infrastructure as top needs across the institution. In April 2023, the Data Science Lab team, along with Legal, Compliance, and IT, finalized a new agreement with University of Washington that enables comprehensive data access and use.

These exciting new opportunities for use of Fred Hutch Cancer Center’s patient clinical data depend on the development of expanded data infrastructure and new data governance and stewardship policies. DaSL and its partners at Fred Hutch Cancer Center have initiated a new data infrastructure approach and a new data governance approach for clinical data. This new approach envisions a future Fred Hutch Cancer Center with multimodal data integration and democratized data access.

Medical Record Data

For now, medical record data for cancer consortium patients is available for research through the legacy repository of clinical data extracted from UW Medicine Analytics systems. This legacy repository is referred to as HIDRA (Hutch Integrated Data Repository and Archive), and the source of data is primarily from UW Medicine’s Clarity/DEEP tables. Previously, other sources were used before UW Medicine consolidated their electronic health record activities into Epic (e.g., UW Medicine’s Amalga analytics platform). The legacy repository includes tables such as demographics, lab values, encounters, diagnosis codes, radiation oncology, and a variety of unstructured radiology, pathology, and clinical narrative reports. Currently, to request access to these data, go to the Fred Hutch Patient Data for Research page on CenterNet.

Fred Hutch Cancer Center patient population

The patient population included in HIDRA is created by filtering for patients across Fred Hutch Cancer Center and UW Medicine in Clarity. Clarity is the name of the database that contains the unified Epic medical record for Fred Hutch Cancer Center and UW Medicine. Patients are included if they have at least one oncology-related base record in any of Clarity’s data domains (encounters, hospital billing account, professional billing, referral). A base record is defined as the most relevant unit of activity in each of the data domains. Once a set of qualified patients with at least one oncology-related base record in any data domain is identified, records for all care for those patients are brought in (not just care directly related to cancer).

Oncology-related records are defined in a MOU between the UW and Fred Hutch Cancer Center:

1.1 Cancer-Related Care: Includes,

1.1.1 Care provided to individuals who have had a cancer diagnosis in their lifetime at any SCCA or UW Medicine facility.

1.1.2 Care related to bone marrow/stem cell transplants or immunotherapy for donors and recipients without a cancer diagnosis.

1.1.3 Care provided to individuals who have a cancer-related condition (e.g. benign neoplasm), which shall include any care regardless of whether it is related to such cancer-related condition.

1.1.4 Care related to cancer screening (e.g. mammograms, pap smears, colonoscopies, certain imaging scans) and specific cancer prevention activities (e.g. HPV vaccine).

This definition which outlines which patients and records are included in HIDRA is the same definition used for the databases that contain clinical data for support of oncology-related clinical and operational activities (The Data Platform/CEDAR).

Manually Abstracted Data

Until November of 2022, STTR used a data management platform called Caisis to facilitate data abstraction for translational research. Manually abstracted data built upon the discrete data elements available in HIDRA. These additional data elements create a story about individual patient’s clinical experiences and health status throughout their treatment at FHCC or UW Medicine.

Approximately 30 fields from HIDRA were fed directly into Caisis, along with a linkage to SEER data which pulled in death dates when available. Abstracted data elements were recorded in discrete fields, per data dictionaries which were set up by consensus by multiple members of each program. Wherever possible, data elements were standardized across disease programs, enabling data sharing across programs and larger research questions to be answered in the future. All data in Caisis was audited (real-time auditing was performed on at least 10% of patients entered for each program). To view fields and disease-specific data dictionaries, see the Fred Hutch Ontology Browser.

There are 12 programs with data abstracted into Caisis:

• Brain
• Breast
• Colorectal
• Head & Neck
• Lung
• Liver
• Lymphoma
• Myeloma
• Pancreas
• Prostate
• Sarcoma
• Thyroid
• Leukemia

Data abstracted into Caisis is still available to any Cancer Consortium investigator, with valid IRB approval or for activities preparatory to research. Currently, STTR is developing new tools for data abstraction. See STTR’s newsletter to stay informed about new data abstraction tools.
