Study summary

The aim of this study is to investigate the procedure efficiency, organisational and economic impact, and physician evaluation of the conventional reusable rhino laryngoscope vs. Ambu® aScope™ 4 RhinoLaryngo in procedures conducted distally form the ENT department e.g. in the emergency department (ED), intensive care unit (ICU), ward etc., i.e. consults.

Read the detailed description

The aim of this study is to investigate the procedure efficiency, organisational and economic impact, and physician evaluation of the conventional reusable rhinolaryngoscope vs. Ambu® aScope™ 4 RhinoLaryngo in procedures conducted distally from the ENT department e.g. in the emergency department, intensive care unit, ward etc., i.e. consults.

The study will be prospective and randomised until 13 procedures have been performed in each group followed by an assessment of the organisational impact and cost comparison of the two technologies. The investigator will track the time and evaluate the device after each procedure. The organisational impact will be accessed by a questionnaire following the study period. A cost comparison will be enabled via tracking all the processes associated with the rhinolaryngoscopes. After tracking all equipment, time, and utilities will be ascribed a cost.

What researchers measure

Primary outcomes

  1. Pre-procedure time from notification of the physician to start of rhinolaryngoscopy.

    The time (minutes) from indication of the need for a rhinolaryngoscopy, as registered by the physician until initiation of rhinolaryngoscopy. The mean time registered for the experimental arm will be compared to the active comparator arm to assess differences.

    Time frame: Prior to procedure

Secondary outcomes

  1. Availability assessed as the time from indication of the need of the rhinolaryngoscopy until the physician leaves to conduct the rhinolaryngoscopy.

    Time (minutes) from indication of the need for rhinolaryngoscopy until the investigator leave to conduct the rhinolaryngoscopy. The mean time registered for the experimental arm will be compared to the mean time registered for the active comparator arm to assess differences.

    Time frame: Prior to procedure

  2. Time from indication for the need of rhinolaryngoscopy until the procedure is completed.

    Time from indication for the need of rhinolaryngoscopy until the rhinolaryngoscope has been fully removed from the patient. The outcome will be reported as the area under the curve compared between experimental and active comparator arm.

    Time frame: Within 24 hours after completion of procedure.

  3. Organisational impact - User preference for type of rhinolaryngoscope assessment of work process.

    User preference assessment of parameters for rhinolaryngoscopy work process (1. Free of wear and tear, 2. Training and education of students, 3. Recording and saving images and videos). Responses rated through 3-point scale - favorable to: 1. Ambu single-use rhinolaryngoscope or 2. conventional reusable rhinolaryngoscope or 3. neutral. Results distributed in percentages.

    Time frame: Up to 26 weeks after study completion

  4. Organisational impact - User preference for type of rhinolaryngoscope for workflow.

    Comparison between workflows for the experimental arm or active comparator. Assessed as the preference of the treating physician through a 3-point scale - favorable to: 1. Ambu single-use rhinolaryngoscope or 2. conventional reusable rhinolaryngoscope or 3. neutral. Results distributed in percentages.

    Time frame: Up to 26 weeks after study completion

  5. Organisational impact - User evaluation for type of rhinolaryngoscope based on time until start of rhinolaryngoscopy.

    User evaluation of which rhinolaryngoscope is expected to have the longest time interval from indication for rhinolaryngoscopy until the start of the procedure, based on previous experience. Response through 3-point scale - favorable to: 1. Ambu single-use rhinolaryngoscope or 2. conventional reusable rhinolaryngoscope or 3. neutral. Results distributed in percentages.

    Time frame: Up to 26 weeks after study completion

  6. Organisational impact - User preference for type of rhinolaryngoscope based on patient/carer involvement in procedure.

    User assessment of which rhinolaryngoscope is the most cumbersome to involve patients or carers in the procedure and subsequent diagnosis or clinical decision (e.g. show or present the procedure and findings during or following the procedure). Response through 3-point scale - favorable to: 1. Ambu single-use rhinolaryngoscope or 2. conventional reusable rhinolaryngoscope or 3. neutral. Results distributed in percentages.

    Time frame: Up to 26 weeks after study completion

  7. Organisational impact- User preference for type of rhinolaryngoscope based on training requirements and skills.
