Abstract
Background
Primary care providers and health systems have prominent roles in guiding effective cancer screening.
Objective
To characterize variation in screening abnormality rates and timely initial follow-up for common cancer screening tests.
Design
Population-based cohort undergoing screening in 2011, 2012, or 2013 at seven research centers comprising the National Cancer Institute-sponsored Population-based Research Optimizing Screening through Personalized Regimens (PROSPR) consortium.
Participants
Adults undergoing mammography with or without digital breast tomosynthesis (n = 97,683 ages 40–75 years), fecal occult blood or fecal immunochemical tests (n = 759,553 ages 50–75 years), or Papanicolaou with or without human papillomavirus tests (n = 167,330 ages 21–65 years).
Intervention
Breast, colorectal, or cervical cancer screening.
Main Measures
Abnormality rates per 1000 screens; percentage with timely initial follow-up (within 90 days, except 9-month window for BI-RADS 3). Primary care clinic-level variation in percentage with screening abnormality and percentage with timely initial follow-up.
Key Results
There were 10,248/97,683 (104.9 per 1000) abnormal breast cancer screens, 35,847/759,553 (47.2 per 1000) FOBT/FIT-positive colorectal cancer screens, and 13,266/167,330 (79.3 per 1000) abnormal cervical cancer screens. The percentage with timely follow-up was 93.2 to 96.7 % for breast centers, 46.8 to 68.7 % for colorectal centers, and 46.6 % for the cervical cancer screening center (low-grade squamous intraepithelial lesions or higher). The primary care clinic variation (25th to 75th percentile) was smaller for the percentage with an abnormal screen (breast, 8.5–10.3 %; colorectal, 3.0–4.8 %; cervical, 6.3–9.9 %) than for the percentage with follow-up within 90 days (breast, 90.2–95.8 %; colorectal, 43.4–52.0 %; cervical, 29.6–61.4 %).
Conclusions
Variation in both the rate of screening abnormalities and their initial follow-up was evident across organ sites and primary care clinics. This highlights an opportunity for improving the delivery of cancer screening through focused study of patient, provider, clinic, and health system characteristics associated with timely follow-up of screening abnormalities.
