About this study

The purpose of this study is to gather information about the long term health of people who have been prescribed the Cologuard test, which is used for colorectal cancer (CRC) screening.

Read the detailed description

Participates will be consented for prospective follow-up for health outcomes, which will be ascertained through periodic contacts. Participants will complete a baseline health questionnaire survey (T0) and a 1-year follow-up questionnaire survey (T1), allow access to medical records, when available, and allow future contacts for additional surveys.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Enrollment of Subjects

    Enrollment of 150,000 subjects

    Measured: 3 years

Secondary outcomes (3)
  1. Diagnostic colonoscopy

    Proportion having diagnostic colonoscopy within 1 year after positive CG test

    Measured: 4.5 years

  2. CRC Frequency

    Frequency of CRC among enrollees

    Measured: 10 years

  3. National Rates Comparison

    Comparison with national rates (i.e., SEER cancer registry rates) adjusted to reflect a) the age- and sex- distribution of CG users, b) that 25% of colorectal cancers occur in high risk patients, and c) the attrition rate of our longitudinal cohort

    Measured: 10 years
