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.
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.

| Conventional reusable rhinolaryngoscope | Device | Patient indication following a rhinolaryngoscopy |
|
| Prior to procedure |
| 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. | Within 24 hours after completion of procedure. |
| Organisational impact - User preference for type of rhinolaryngoscope assessment of work process. | User preference assessment of parameters for rhinolaryngoscopy work process (1.
