Background
Despite national policy efforts to increase colorectal cancer (CRC) screening, rates in vulnerable populations remain suboptimal. Many types of interventions have been employed, but their impact on improving population-level rates of CRC screening over time is uncertain.
Objective
Assess the impact of 10 years of different in-reach and outreach strategies to improve CRC screening and identify factors associated with being screen up-to-date (SUTD).
Design
Observational cohort study.
Participants
Patients aged 50–74 years from 12 community-based primary care clinics in an integrated, regional safety-net health system.
Interventions
Multiple system-level interventions were implemented over time (visit-based electronic health record [EHR] reminders, quality measurement, annual preventive service letters, and mailed fecal immunohistochemical stool tests [FIT]).
Main Measures
CRC SUTD rates by calendar year among those with a primary care (PC) visit in the prior 1 and 3 years and their multivariable correlates.
Key Results
The sample included 31,786–40,405 patients/year. In 2011, mean age was 58.9, 63.9% were women, 37.0% were Hispanic, 39.3% Black, 16.8% White, and 6.6% Asian/Other, and 60.5% were uninsured/Medicaid. Three-quarters of patients had ≥ 1 PC visit in the prior year. Lower-intensity interventions (EHR reminders, quality measurement, annual prevention letters) had limited impact on SUTD rates (2–3% rise). Implementing system-wide mailed FIT increased rates from 51.2 to 61.9% among those with a PC visit in the past year (40.5 to 46.8% with a PC visit ≤ 3 years). Stopping mailed FIT due to COVID wiped out these gains. Higher screening rates were associated with the following: older age; female; more comorbidities, PC clinic visits, and prior FITs; and better insurance coverage. Hispanics had the highest SUTD rates followed by Asians, Blacks, and Whites (p < 0.05).
Conclusions
Implementation of a system-wide mailed FIT program had the greatest impact on SUTD rates. Lower-intensity interventions (EHR reminders, quality measurement, and patient letters) had limited effects.
