Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Prospective french multicentre observational study, during one month: from March 6th to April 6th 2017, under the auspice of the IBD group of the Société Française d'Endoscopie Digestive- SFED. All French gastroenterologists in charge of IBD patients in public or private endoscopy centers were reached out through various professional and scientific associations to participate in the study via e-mail, web sites, and national congresses. Investigators were asked to prescribe the bowel preparation independently from the study, as per their usual habits. The achievement of low residue diet, the split and the timing of the preparation were left free to the investigator according to local protocols.

Data recording The physicians participating in the study completed data on an online questionnaire via an internet-based tool (CleanWeb software, hosted by Besançon university hospital research center) or through a questionnaire sheet. The questionnaire included a medical record and a self-reported patient questionnaire. The medical record included physicians and centers characteristics, patient's demographics, disease characteristics, modality of bowel preparation (diet, split dose, type of bowel preparation, delay before colonoscopy), and colonoscopy findings and outcomes. Patients self-administered questionnaires assessed preparation tolerability by symptoms and satisfaction recording.

Clinical endpoints The efficacy of the preparation was evaluated by the Boston's score (efficacy was defined as a Boston's score was ≥ 7 without any segment <2)23, the rate of caecal or anastomosis intubation and the necessity or not to repeat the colonoscopy.

The tolerance was evaluated by the quantity of preparation actually absorbed by the patient, (quantity of active preparation and quantity of clear liquid), patients and investigators visual analogue scale evaluation of tolerance (VAS), a self-administered validated bowel-preparation tolerability questionnaire 24 and by the patients' wish to take the same preparation for the next colonoscopy.

Safety data: adverse events were collected per preparation and per endoscopic procedure, at 24 hours and 30 days later. A special focus was made on aphtoid lesions as they were previously reported as adverse preparation-induced mucosal lesions possibly associated with some solutions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients with an indication of colonoscopy independent from the study

Description

Inclusion Criteria:

  • Patient aged 18-75 years,
  • symptoms of IBD for at least 3 month,
  • inidcation of colonoscopy independent from the study.

Exclusion Criteria:

  • Congestive heart failure,
  • severe renal failure,
  • gastro intestinal symptomatic obstruction or occlusive bowel stenosis (a non-occlusive stenosis was not an exclusion criterion),
  • severe acute colitis,
  • severe dehydration or electrolyte disturbances,
  • patient's refusal to participate in the study.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Boston Score
Time Frame: 30 days
According to the rate of complete colonoscopy (caecal intubation); and according to the need to reschedule the examination
30 days

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
tolerance: visual analogue scale
Time Frame: 30 days
visual analogue scale
30 days
adverse events per procedure
Time Frame: 30 days
fever, bowel perforation, bleeding, inhalation, hospitalisation, disease flare
30 days

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (ACTUAL)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 2, 2017

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
