• Bowel Preparation

Intervention

Drug:
• PicoPrep
PICOPREP (sodium picosulfate, magnesium oxide and citric acid) powder for oral solution consisted of 2 pouches of powder administered in a divided dose. Each PICOPREP pouch was reconstituted by mixing the contents in a cup with 5 ounces of cold water. The first pouch was taken between 5:00 PM and 9:00 PM the evening prior to the colonoscopy procedure. Subjects were to consume five (5) 8-ounce glasses of clear liquids over the next few hours. The second pouch was taken approximately 5 hours before but no more than 9 hours prior to the colonoscopy procedure. Subjects were to consume three (3) 8-ounce glasses of clear liquids.
• HalfLytely
HalfLytely contains polyethylene glycol electrolyte solution (PEG-EL), sodium chloride, sodium bicarbonate and potassium chloride. The day prior to the colonoscopy procedure and after the first bowel movement or after 6 hours following administration of the bisacodyl tablets, whichever occurred first, subjects were to drink the 2 liter HalfLytely at a rate of one 8-ounce glass every 10 minutes. The entire solution was to be consumed.
• bisacodyl
Two 5 mg bisacodyl tablets were taken in the afternoon on the day prior to the colonoscopy procedure.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants Classified as Successes (Excellent and Good Ratings) According to the Aronchick Scale As Assessed by a Blinded Gastroenterologist	Overall colon cleansing was assessed by a blinded gastroenterologist during the colonoscopy using the Aronchick scale. The Aronchick scale is a 4-step rating scale: inadequate, fair, good, and excellent. Excellent is defined as >90% of mucosa seen, mostly liquid stool, minimal suctioning needed for adequate visualization. Good is defined as >90% of mucosa seen, mostly liquid stool, significant suctioning needed for adequate visualization.	Day 2	No
Secondary	Percentage of Participants Classified as Successes (Excellent, Good and Fair Ratings) According to the Ottawa Scale As Assessed by a Blinded Gastroenterologist	Overall colon cleansing was assessed by a blinded gastroenterologist during the colonoscopy using the Ottawa scale, a 5-step rating scale: inadequate, poor, fair, good, and excellent. Excellent is defined as mucosal detail clearly visible; if fluid is present, it is clear and there is almost no stool residue. Good - some turbid fluid or stool residue but mucosal detail still visible; washing and suctioning is not necessary. Fair - turbid fluid or stool residue obscuring mucosal detail. However, mucosal detail becomes visible with suctioning and washing is not necessary.	Day 2	No
Secondary	Percentage of Participants' Responses to the Acceptability and Tolerability Questionnaire: How Easy or Difficult Was It To Consume the Study Drug?	Participants answered the question above on Day 2 prior to the colonoscopy procedure. Answers were on a 5-point scale: very easy, easy, tolerable, difficult, very difficult	Day 2	No
Secondary	Percentage of Participants' Responses to the Acceptability and Tolerability Questionnaire: Were You Able to Consume the Entire Prep As Instructed?	Participants answered the question above on Day 2 prior to the colonoscopy procedure. Answers were on a 2-point scale: yes, no	Day 2	No
Secondary	Percentage of Participants' Responses to the Acceptability and Tolerability Questionnaire: Please Describe Your Overall Experience With the Study Preparation	Participants answered the question above on Day 2 prior to the colonoscopy procedure. Answers were on a 5-point scale: Excellent, Good, Fair, Poor, Bad	Day 2	No
Secondary	Percentage of Participants' Responses to the Acceptability and Tolerability Questionnaire: The Taste of This Study Preparation Was	Participants answered the question above on Day 2 prior to the colonoscopy procedure. Answers were on a 5-point scale: Excellent, Good, Tolerable, Poor, Bad	Day 2	No
Secondary	Percentage of Participants' Responses to the Acceptability and Tolerability Questionnaire: Would You Ask Your Doctor for This Preparation Again if You Need Another Colonoscopy in the Future?	Participants answered the question above on Day 2 prior to the colonoscopy procedure. Answers were on a 2-point scale: yes, no	Day 2	No
Secondary	Percentage of Participants' Responses to the Acceptability and Tolerability Questionnaire: Would You Refuse the Same Preparation Again if it Were to be Prescribed to You in the Future?	Participants answered the question above on Day 2 prior to the colonoscopy procedure. Answers were on a 2-point scale: yes, no	Day 2	No
Secondary	Participants With Treatment-Emergent Adverse Events (TEAEs)	Counts of participants who had TEAEs are summarized in a variety of categories. Severity and relatedness to study drug are in the opinion of the investigator. Severity is rated on a 3-point scale: mild (awareness of signs or symptoms, but no disruption of usual activity), moderate (event sufficient to affect usual activity), and severe (inability to work or perform usual activities). Only severe TEAEs are summarized. Relatedness is assessed on a 4-point scale: unrelated, unlikely, possibly and probably. Both possibly and probably answers are reported as 'related' to study medication.	up to one month	No
