Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
It has been shown that providing outpatients with simple, but specific instructions regarding the importance and mode of adequate preparation - either through a leaflet, a sms or on the web - improves significantly the level of bowel cleanliness. However, data regarding the success of such an intervention in inpatients lack.
Aim To study the impact of providing specific verbal instructions in inpatients (and/or their relatives) undergoing colonoscopy on the quality of bowel preparation.
Patients - Methods Study Design This is a prospective, randomized, single-blinded study. Four Greek academic endoscopy departments will competitively enroll patients during a period of 6 months.
Randomization A central randomization list will be computer-assisted, created and sent to one collaborator of each center. Endoscopists will be blinded to participant's group.
300 patients will be randomized in 2 groups, in blocks of 10 with an analogy 1:1. They will also be stratified in a 60%-40% percentage depending on whether the patient is bedridden or not at the time of the examination
Statistical Analysis According to the literature similar interventions showed a gain of 20% in favor of the intervention. Statistical significance level α is defined 5% and the study is powered at the level of 80%. According to data from Hepatogastroenterology Unit of Attikon University General Hospital regarding the adequateness of bowel preparation of patients undergoing colonoscopy and with an expected 10% drop out, 300 patients are needed (including a 10% drop out) in order to succeed 18% improvement of the primary endpoint (from 66% for inpatients during 2015 to 84% for outpatients during the same period) favoring the intervention group. Interim analysis and sample size re-estimation will be undergone after data collection from 90 patients.
Both an intention to treat (ITT) and a per protocol (PP) analysis are planned. Data will be recorded in predefined CRFs.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group A
Participants getting SPECIFIC VERBAL INSTRUCTIONS before starting bowel preparation (Group A).
SPECIFIC VERBAL INSTRUCTIONS
Participants will be randomized either to get detailed instructions verbally by the medico-paramedical staff of the participating centers (physicians or nurses) before starting bowel preparation (Group A) or to get ordinary instructions as usual in each of the participating centers (Group B). Instructions provided to Group A will include details about the procedure of bowel preparation, its potential side effects and the importance of the adequate preparation (Appendix)
Group B
Participants getting ordinary instructions as usual in each of the participating centers (Group B).
No interventions assigned to this group
