Overview

  • Kaiser Permanente Northern California's 20-year colorectal cancer screening program increased screening rates from 37.4% in 2000 to 79.8% in 2019.
  • The program achieved a 30% reduction in colorectal cancer incidence and a 50% decline in mortality across all racial and ethnic groups.
  • Racial disparities in colorectal cancer outcomes were nearly eliminated, with Black patients experiencing the largest reductions in mortality rates.
  • Key strategies included centralized reminders and mailing fecal immunochemical test (FIT) kits directly to patients’ homes, offering multiple screening options like colonoscopy and FIT.
  • The program serves as a replicable model for addressing health disparities and improving outcomes in other chronic conditions through organized, equitable outreach.
