What researchers measure

Primary outcomes

  1. Efficacy - Entire colon

    Successful cleansing defined as score or excellent or good Unsuccessful cleansing defined as score of fair or inadequate

    Time frame: At time of colonoscopy

Secondary outcomes

  1. Efficacy - Right colon

    Successful cleansing defined as score or excellent or good Unsuccessful cleansing defined as score of fair or inadequate

    Time frame: At time of colonoscopy

  2. Adenoma detection

    Defined as number of adenoma/patient Secondarily evaluate % of patients with at least 1 adenoma

    Time frame: at time of colonoscopy

  3. Flushing

    Defined as need for any (1, 2, or 3) flushing • 0 = none, 1 = \<50 ml, 2 = 50-100 ml, 3 = \>100 ml

    Time frame: at time of colonoscopy

  4. Tolerance

    Prep completion • Completion defined as consuming \> 90% Sleep * Primary definition as quality of sleep * Also evaluate duration of sleep Overall satisfaction * Use visual analogue (Likert) scale Adverse events - nausea, vomiting, abdominal pain, bloating, light-headedness * Primary is incidence * Secondary is severity using Likert scale

    Time frame: during prep ingestion
