Evaluation of One-day Polyethylene Glycol Powder Solution for Colonoscopy in Children

This study has been completed.

The purpose of this study is to examine the effects of current standard of care Polyethylene Gylcol powder (PEG-P)colonoscopy preparation on a patient's serum electrolytes, tolerance of the prep, and how well the bowel is cleansed. The primary aim is to determine the proportion of patients with clinically significant serum electrolyte abnormalities at the time of colonoscopy and how well the prep is tolerated. Secondary objectives include: 1) how well the bowel is cleansed with this preparation, and 2) to determine the most effective way to communicate instructions about the bowel preparation with the child and family.

Condition Intervention
Water-Electrolyte Imbalance Drug: polyethylene glycol powder

Study Type: Observational
Study Design: Observational Model: Case-Only
Time Perspective: Prospective

Further study details as provided by Petar Mamula, Children's Hospital of Philadelphia:

Primary Outcome Measures:
  • electrolyte disturbances [ Time Frame: at the time of colonoscopy ]
    the proportion of patients with clinically significant serum electrolyte abnormalities at the time of colonoscopy

  • PEG-P preparation tolerance [ Time Frame: at the time of colonoscopy ]
    Responses to a questionnaire regarding the tolerance of the PEG-P prep will be recorded

Secondary Outcome Measures:
  • Colonoscopy preparation efficacy [ Time Frame: at the time of colonoscopy ]
    To assess the proportion of patients that have excellent or good quality preparation as scored by a validated residual stool survey called the Aronchick scale

  • Effective communication [ Time Frame: at the time of colonoscopy ]
    Effectiveness of communication strategy about the prep and availability of staff to address questions reported by parents will be summarized

Biospecimen Description:
No biospecimens are to be retained

Enrollment: 178
Study Start Date: June 2012
Study Completion Date: January 2014
Primary Completion Date: January 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
PEG-P prep
Children taking the one day polyethylene glycol powder preparation for outpatient colonoscopy
Drug: polyethylene glycol powder
A single group of children taking a polyethylene glycol powder preparation, dosage determined by patient weight, taken in one dose the day before colonoscopy

Detailed Description:
Design is prospective, descriptive observational study involving a single clinical encounter in the Endoscopy suite at CHOP Main at the time of colonoscopy. Patients prescribed the standard of care dosage for PEG-P by their primary gastroenterologist are considered for this study. Study procedures include collection of data from patients that are prescribed the PEG-P dose. In order to evaluate the safety, tolerability, and adherence to PEG-P bowel preparation, data collections include the following: review of medical records, tracking of communication from subjects/parents, blood draw, questionnaire and quality of prep will be assessed. Questionnaire results will be obtained at the initial and only visit. Patients will be given a questionnaire prior to colonoscopy to rate symptoms, ease of preparation and to rate the effectiveness of communication about the preparation. On the day of colonoscopy, prior to the procedure, patients will have an IV placed per standard procedure. At the time of IV placement, a basic metabolic panel and serum magnesium and phosphorus levels will be drawn through the IV for assessment of electrolyte abnormalities. Serum glucose will be captured from medical records as this is collected with standard of care. Patient/parents will grade the preparation tolerance filling out a questionnaire prior to colonoscopy. During colonoscopy, the endoscopist will grade the quality of preparation on a validated residual stool survey (Aronchick scale).
