Trends in Wait Time for Colorectal Cancer Screening and Diagnosis 2013-2016.

Objectives: Colorectal cancer (CRC) screening has increased in the United States during the past 20 years, resulting in an increased demand for colonoscopy. We tested the hypothesis that such increase resulted in longer wait times for colonoscopy and influenced CRC diagnosis.

Methods: A total of 36,623 consecutive colonoscopies performed at the University of Wisconsin from April 8, 2013, until December 31, 2016, were included in the analysis.
