CLABSI - Central Line Associated Bloodstream Infection, CRBSI - Catheter Related Bloodstream Infection, Digital Technology
Conditions
Brief summary
Background: In critical care medicine central venous catheters play an important role in the source of infections. In the daily routine prior to the diagnosis the suspicion of catheter related infection is discussed in the medical team due to signs of systemic inflammation or exit site infection like erythema, induration or tenderness. However, if an erythema at exit site of a central line can be quantified with a tablet camera, is unknown. Methods: Standardized set of photos will be taken of 10 central lines with a reddened exit site and 10 catheters without an erythema (as a control over time) with a tablet camera and a single-lens reflex camera. The percentage of usable images between tablet and single-lens reflex camera will be analysed. Furthermore, two independent clinical experts from dermatology will grade blinded de-identied images on a scale from 0 to 4 (0 - no erythema, 1- very faint, 2 - faint, 3 - bright, 4 - very bright). Objectives: The primary objective of this feasibility study aims to analyze the reliability of a tablet camera as a device for quantification of erythema around an exit site.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of usable images | through study completion, an average of 3 months | The percentage of useable images of tablet camera compared with single-lens reflex (SLR) camera will be analysed. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Quantification of the exit site with regards to an erythema scale | through study completion, an average of 3 months | The secondary objective aims to evaluate the quantification of the exit site regarding to the erythema scale by two independent clinical experts comparing images of tablet and SLR camera. The erythema will be graded using a visual ordinal scale (grade 0 to grade 4). Grade 0 represents no erythema, whereas grade 4 describes a very bright erythema. |
