Primary Outcome Measures:
  • ODDS ratio for unsedated colonoscopy acceptance [ Time Frame: up to 8 months ] [ Designated as safety issue: No ]
    Multivariate analysis was used to assess the association of dempgraphics (gender, age, level of education) and clinical features (indication to the procedure, history of abdominal surgery or irritable bowel syndrome, presence of pain as main symptom, chronic use of sedative medications, level of patient's anxiety (none, mild, moderate or severe), main concern about the examination and reason for willing to attempt unsedated procedure) to the acceptance of unsedated colonoscopy


Secondary Outcome Measures:
  • Acceptance rate of unsedated colonoscopy [ Time Frame: up to 8 months ] [ Designated as safety issue: No ]
    Proportion of patients accepting to attempt colonoscopy without routine premedication

  • ODDS ratios for unsedated colonoscopy completion [ Time Frame: up to 8 months ] [ Designated as safety issue: No ]
    Multivariate analysis was used to assess the association of dempgraphics (gender, age, level of education) and clinical features (indication to the procedure, history of abdominal surgery or irritable bowel syndrome, presence of pain as main symptom, chronic use of sedative medications, level of patient's anxiety (none, mild, moderate or severe), main concern about the examination and reason for willing to attempt unsedated procedure) to the completion of unsedated colonoscopy

Groups/Cohorts Assigned Interventions
Colonoscopy outpatients
All patients referred to our Unit to undergo colonoscopy for any indication
Procedure: Unsedated colonoscopy
Patients were offered to undergo colonoscopy without routine premedication
Procedure: Unsedated colonoscopy
Patients were offered to undergo unsedated procedure. Their demographics and clinical data were recorded

Detailed Description:

Patients were offered to undergo colonoscopy without routine premedication. In case of both acceptance and refusal, a brief questionnaire recording demographics (gender, age, level of education) and clinical features was prospectively recorded in a standard data sheet by one of the four endoscopists at enrollment. Clinical features recorded for each patient included: indication to the procedure, history of abdominal surgery or irritable bowel syndrome, presence of pain as main symptom, chronic use of sedative medications, level of patient's anxiety (none, mild, moderate or severe), main concern about the examination and reason for willing to attempt unsedated procedure.
