PräBea: Innovative Feedback System for Hand Hygiene in Intensive Care

From 2020 to 2021, GWA Hygiene led as consortium coordinator the BMBF project PräBea, a pioneering project to improve hand hygiene in inpatient intensive care. The successful implementation and evaluation of the system was recently published in the renowned Journal of Hospital Infection. ## Innovative Technology Combination The project combined two advanced technologies: 1. **NosoEx System** - Proven hand hygiene monitoring - Digital recording of disinfection events - Data analysis and reporting 2. **HyHelp Technology** - Innovative ceiling-mounted sensor unit - Detection of entries and exits in the patient environment - Automatic compliance verification ## Project Locations The system was implemented at two locations: ### BDH Clinic Greifswald - Main site of the PräBea project - Integration into the intensive care unit - Complete system implementation ### University Medicine Greifswald - Predecessor project with HyHelp technology - Important insights for PräBea - Successful piloting ## System Operation The innovative monitoring system works on multiple levels: 1. **Motion Detection** - Precise tracking of personnel movements - Identification of entries and exits - Automatic documentation 2. **Hygiene Monitoring** - Verification of hand disinfection before entry - Control of hand disinfection after exit - Real-time feedback 3. **Data Analysis** - Automatic compliance calculation - Trend analysis - Scientific evaluation ## Scientific Validation The project results were comprehensively documented and validated: ### Publication - Journal: Journal of Hospital Infection - Peer review process - International recognition - [Full Publication](https://www.journalofhospitalinfection.com/article/S0195-6701(23)00007-5/fulltext) ### Project Documentation - Detailed methodology description - Evaluation results - Implementation guidelines - [Project Website](https://www.interaktive-technologien.de/projekte/praebea) ## Outlook The successful completion of the PräBea project marks an important milestone: - Validation of the technology combination - Proof of practical applicability - Foundation for further implementations - Contribution to improving patient safety The project demonstrates the potential of digital solutions for improving hand hygiene in intensive care and lays the groundwork for further innovations in this field.
