Racial and Ethnic Disparities in Interval Colorectal Cancer Incidence: A Population-Based Cohort Study.

ABSTRACT:

Background

Interval colorectal cancer (CRC) accounts for 3% to 8% of all cases of CRC in the United States. Data on interval CRC by race/ethnicity are scant.

Objective

To examine whether risk for interval CRC among Medicare patients differs by race/ethnicity and whether this potential variation is accounted for by differences in the quality of colonoscopy, as measured by physicians' polyp detection rate (PDR).

Design

Population-based cohort study.

Setting

Medicare program.

Participants

Patients aged 66 to 75 years who received colonoscopy between 2002 and 2011 and were followed through 2013.

Measurements

Kaplan-Meier curves and adjusted Cox models were used to estimate cumulative probabilities and hazard ratios (HRs) of interval CRC, defined as a
