Abstract

Background & Aims: Screening decreases colorectal cancer (CRC) incidence and mortality. Colonoscopy has become the most common CRC screening test in the United States, but the degree to which it protects against CRC of the proximal colon is unclear. We examined US trends in rates of resection for proximal vs distal CRC, which reflect CRC incidence, in the context of national CRC screening data, before and since Medicare's 2001 decision to pay for screening colonoscopy. Methods: We used the Nationwide Inpatient Sample, the largest US all-payer inpatient database, to estimate age-adjusted rates of resection for distal and proximal CRC, from 1993 to 2009, in adults. Temporal trends were analyzed using Joinpoint regression analysis. Results: The rate of resection for distal CRC decreased from 38.7 per 100,000 persons (95% confidence interval [CI], 35.4-42.0) to 23.2 per 100,000 persons (95% CI, 20.9-25.5) from 1993 to 2009, with annual decreases of 1.2% (95% CI, 0.1%-2.3%) from 1993 to 1999, followed by larger annual decreases of 3.8% (95% CI, 3.3%-4.3%) from 1999 to 2009 (P
