NCT05921136

Brief Summary

The present trial is an observational prospective trial. The aim of the present study is to analyse the recycling potential in endoscopy units in hospitals and outpatient facilities. For this purpose, waste is collected for four weeks each at four locations (two inpatient and two outpatient facilities). Questions such as quantity and quality of garbage will be addressed and compared between the different facilities.

Outcome Measures

Primary Outcomes (1)

  • Amount of waste generated per examination in grams (g)

    The amount of waste per procedure will be collected by weighing the garbage of after every procedure.

    16 weeks

Secondary Outcomes (7)

  • Parts of waste per examination in g (residual waste, plastic, paper).

    16 weeks

  • Saving potential defined by the amount of reusable items in g per procedure (e.g. gowns)

    16 weeks

  • Comparison of the amount of waste in g in disposable vs. reusable endoscopes.

    16 weeks

  • Descriptive description of the amount of waste after 4 weeks in kg and per produre in g at the different locations.

    16 weeks

  • Statistical comparison of the amount of waste in the different locations

    16 weeks

  • +2 more secondary outcomes
