Inclusion criteria
Inclusion criteria: 1.Endoscopes that were used in the course of an examination on a patient in the endoscopy department of a university hospital 2.Endoscopes that have undergone the entire reprocessing process (depending on the study group).
Exclusion criteria
Exclusion criteria: 1. No endoscopic examination being performed at a patient (e.g. termination of the endoscopy before the start of the examination due to restricted cardiorespiratory situation of the patient, although the endoscope was already in the examination room). 2.Incomplete reprocessing (e.g. positive leak test). 3.Reuse of the endoscope before completion of the storage interval according to the present study protocol (in this case, the endoscope can be used at least in an intention-to-treat analysis for the samples already collected)
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome measure is the distribution of the qualitative bacterial count (detectable versus absent) on the respective day of sampling in comparison between control and intervention group. Samples are taken as a pooled sample from all endoscopic channels. Microbiological cultivation and evaluation of the samples is performed by qualified staff of the Institute of Medical Microbiology and Hospital Hygiene, Hygiene Laboratory. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary outcome measures are as follows: -Distribution of quantitative microbial count by colony forming unit (CFU) on the respective day of sampling in comparison between control and intervention group. -Distribution of wet germs (qualitative [detectable versus absent] and quantitative by colony forming unit (CFU) in comparison between control and intervention group. Evaluation of qualitative/quantitative moisture detection after mechanical drying (control group) versus drying by PlasmaTYPHOON (intervention group). -Duration of drying compared between control and intervention group. -Absolute and relative risk reduction of microbial colonization compared between control and intervention groups. | — |
