About this study

The aim of this study is to investigate whether single-use gastroscopes used bedside can reduce the time from indication to procedure compared with re-usable gastroscopes used at the endoscopy unit in patients referred to a subacute gastroscopy.

Participants in the first period will be scheduled for gastroscopy with a re-usable gastroscope in the endoscopy unit, whereas participants during the second period will have a gastroscopy performed at the ward (bed-side) with a single-use gastroscope.

Being tested
Ambu aScope Gastro, Diagnostic gastroscopes, Olympus

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Time from the indication/decision for early endoscopy to procedure

    Measured: From indication to procedure, up to two weeks

Secondary outcomes (12)
  1. Time from indication to the discharge

    Measured: From indication to discharge, up to 3 months

  2. Time from procedure to discharge

    Measured: From procedure to discharge, up to 3 months

  3. Duration of the procedure

    Measured: During the procedure

  4. Did the patient need sedation or local anesthetic throat spray

    Measured: During the procedure

  5. Technical success

    Technical success is defined as the ability to complete the procedure adequately based on the indication and guidelines.

    Measured: From admission to discharge, up to 3 months

  6. Sufficient ability to target the biopsy if taken

    Successful biopsy that provides the pathologist with sufficient material to either confirm or rule out a diagnosis. If the biopsy is inadequate, the pathologist will note this in the report.

    Measured: During the procedure

  7. Complications to gastroscopy

    Measured: 24 and 72 hour follow-up after procedure

  8. 30th day mortality

    Measured: 30 days

  9. Readmission

    Does the patient need readmission after discharge?

    Measured: 30 days after procedure

  10. The necessity for a new gastroscopy, including the reasons justifying it

    Did the patient need a new gastroscopy during admission? If so, what is the reason for that, according to the patient's medical record?

    Measured: During admission, up to 3 months

  11. Endoscopists' rating of the gastroscope

    The endoscopist's rating of the gastroscope

    Measured: Right after procedure

  12. Learning curve for nurses at the surgical department

    Following each procedure, the nurses will complete a short questionnaire evaluating their level of comfort (from 1-5) during the various steps of the procedure.

    Measured: During the second period (one year)
