Study summary

This prospective Randomized Controlled Trial will evaluate efficacy, safety, and pharmacoeconomic outcomes in patients undergoing colonoscopy with either Digital Sedation using the Aqua© module of the Oncomfort device (Sedakit TM) or the standard of care, intravenous sedation with propofol. The Aqua© module is designed for sedation and management of pain and anxiety related to medical and surgical procedures.

Read the detailed description

This prospective Randomized Controlled Trial will evaluate efficacy, safety, and pharmacoeconomic outcomes in patients undergoing colonoscopy with either Digital Sedation using the Aqua© module of the Oncomfort device (Sedakit TM) or the standard of care, intravenous sedation with propofol. The Aqua© module is designed for sedation and management of pain and anxiety related to medical and surgical procedures.

Participants will be recruited during the anesthesiology consultation conducted in preparation for colonoscopy. Those with indication for screening or diagnostic colonoscopy under conventional intravenous sedation (propofol) and willing to participate will provide their written informed consent and will be randomized (2:1) between two arms:

  1. Experimental arm: Digital Sedation, with rescue intravenous sedation (propofol) if needed upon patient request
  2. Control arm: conventional intravenous sedation (propofol)

The study will be divided into three stages, with randomization (2:1) maintained throughout. In the first stage, accrual will be halted when about 45 patients have been randomized, at least 27 of whom being evaluable patients randomized to the experimental arm. A non-binding futility analysis is planned for the primary outcome. In the second stage, accrual will be halted when about 90 patients have been randomized. A non-binding futility analysis is planned for the primary outcome. If the milestones are met, accrual will be reopened to the second stage and the study will continue to the planned final accrual of 177 patients (118 to experimental and 59 to control arm, respectively). At the end of the recruitment of Stage 1 and 2, an analysis of the secondary outcomes will also be run. Results of these analysis could also impact the decision for pursuing to second/ third stage.

Study arms

  • Experimental
    Digital Sedation

    Digital Sedation with rescue intravenous sedation (propofol) if needed upon patient request

    Device: Aqua© 30 on Oncomfort SedakitTM · Drug: Propofol

  • Active comparator
    Intravenous sedation

    Control arm with conventional Intravenous sedation

    Drug: Propofol

Interventions

  • DeviceAqua© 30 on Oncomfort SedakitTM

    Digital Sedation session consists in a virtual reality software (Aqua© 30 Version 3.0, Oncomfort SA, Waver, Belgium) including a clinical hypnosis script.Patients in the intervention group will undergo a 30-minute Digital Sedation program through a VR headset and headphones. This medical device called Oncomfort SedakitTM has been created to reduce anxiety and pain during medical/ surgical interventions

  • DrugPropofol

    Standard sedation starting doses of 1 µg/ml to 6 µg/ml depending on patient's reaction and titrated incrementally by 0.5µg/ml. Doses are adapted according to the level of comfort and needs of the patient.

What researchers measure

Primary outcomes

  1. To confirm the feasibility of using digital sedation in colonoscopy (stage 1)

    cecal intubation rate, rate of rescue sedation

    Time frame: Day 1

  2. To demonstrate adequate performance of colonoscopy using digital sedation (stage 2)

    cecal intubation rate, rate of rescue sedation

    Time frame: Day 1

Secondary outcomes

  1. To compare patient experience in both arms

    Measure of satisfaction by Likert scale (0 to 5), pain by Visual Analogue Scale (VAS 0 to 10), anxiety by Visual Analogue Scale (VAS 0 to 10), comfort by Visual Analogue Scale (VAS 0 to 10), Preferred type of sedation, Recall of the procedure, Experienced side effects/ AE

    Time frame: Day 1 & Day 2 Follow-up call

  2. To compare measures of colonoscopy performance in both arms

    Compare Cecal intubation rates, Adenoma detection rates, Withdrawal time,Total duration of colonoscopy, Total duration of sedation,Total length of stay in procedure room,Total length of stay in recovery room,Total length of stay in hospital

    Time frame: Day 1

  3. To assess the need for rescue sedation in the experimental arm

    Proportion of patients with cecal intubation without rescue sedation in the experimental arm, Frequency of use of intravenous sedation (propofol) and of complete interruption of digital sedation

    Time frame: Day 1

  4. To compare use of sedation medication in both arms

    Average (per patient) total doses of sedation medication per arm

    Time frame: Day 1

  5. To assess gastroenterologist and anesthesiologist satisfaction in both arms

    Measure of satisfaction by Likert scale (0 to 5) and of perceived facilitation or impediment of the procedure by Digital Sedation as measured by Likert scale (0 to 5)

    Time frame: Day 1

  6. To assess gastroenterologist and anesthesiologist stress in both arms

    Measure of stress by Visual Analogue Scale (VAS 0 to 10)

    Time frame: Day 1

  7. To compare physiologic measures in both arms

    Oxygen saturation (minimal observed during procedure), MBP (min/max.), Heart rate (min/max)

    Time frame: Day 1

  8. To assess difficulty or ease of the procedure in both arms

    Number of abdominal manipulations and patient mobilizations

    Time frame: Day 1

  9. To compare the safety in both arms

    Frequency and type of AEs and SAEs, Frequency and severity of episodes of desaturation and of HR/ MBP changes

    Time frame: Screening, Day 1 & Day 2 Follow-up call
