Developing an algorithm across integrated healthcare systems to identify a history of cancer using electronic medical records.

Objective: Tumor registries in integrated healthcare systems (IHCS) have high precision for identifying incident cancer but often miss recently diagnosed cancers or those diagnosed outside of the IHCS. We developed an algorithm using the electronic medical record (EMR) to identify people with a history of cancer not captured in the tumor registry to identify adults, aged 40-65 years, with no history of cancer.

Materials And Methods: The algorithm was developed at Kaiser Permanente Colorado, and then applied to 7 other IHCS.
