The Clinical Acceptability of Unsedated Colonoscopy

The study was aimed to prospectively evaluate the acceptance rate of unsedated colonoscopy, in a setting where routine sedation for colonoscopy is standard practice and to characterize the subset of patients willing to try and potentially completing an unsedated procedure.

About this study

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.

Treatment and study plan

Unsedated colonoscopy

Procedure

Patients were offered to undergo colonoscopy without routine premedication

Primary outcomes

  1. ODDS ratio for unsedated colonoscopy acceptance

    Time frame: up to 8 months

    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 outcomes

  1. Acceptance rate of unsedated colonoscopy

    Time frame: up to 8 months

    Proportion of patients accepting to attempt colonoscopy without routine premedication

  2. ODDS ratios for unsedated colonoscopy completion

    Time frame: up to 8 months

    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
