Study summary

Colonoscopic examinations are performed routinely in hospitalized patients for a variety of indications. However, numerous limitations exist in hospitalized patients preventing an endoscopist from performing high quality examinations; possibly necessitating repeated procedures leading to increased cost and re-exposure to their inherent risks. One such prominent challenge lays in the adequacy of bowel cleansing. Inpatient status has been shown to be a predictor of poor bowel preparation as these patients are older, less mobile and have more co morbidities than the outpatient population. Currently, no standardized (or optimized) bowel preparation type or regimen for administration exists for the hospital inpatient population undergoing colonoscopy. Studies in the outpatient population have demonstrated that timing and choice of cathartic medication effects the cleanliness of the bowel preparation but there is no such clinical evidence for in-patients who receive whatever cathartic agent is on hospital formulary. The purpose of the study is compare efficacy, patient satisfaction, and adverse effects associated with low volume cathartic (Pico-Salax) to the current standard volume 4 liter (PEG-Lyte) and the effect of alternate timing of dosages.

What researchers measure

Primary outcomes

  1. Ottawa Bowel Prep Score

    Using a standardized, validated score for measuring quality of bowel preparation

    Time frame: 30 minutes after procedure

Secondary outcomes

  1. Procedures Cancelled or repeated due to inadequate bowel preparation

    If bowel preparation is deemed inadequate to the point the procedure must be cancelled or rescheduled

    Time frame: During admission (average of 2 weeks)

  2. Individual Components of Ottawa Bowel Prep Score

    Each section of prep score evaluating the right, mid, and left colon, as well as the fluid score will be analyzed individually

    Time frame: 30 minutes after procedure

  3. Adverse Effects

    Any adverse effects that may be attributed to the intervention

    Time frame: Up to 48 hours after procedure

  4. Tolerability of the preparation

    A questionnaire to assess the overall tolerability of the preparation.

    Time frame: Within 1 day of intervention
