How can a two bed patient room on a normal ward be designed affecting work processes and patient habits to ultimately reduce the transmission of MRSA? This project is an research into how architecture and design can reduce the risk of h ospital-acquired infection.

National and international guidelines call for the isolation of patients with multi-resistant pathogens in single rooms. However, the increasing incidence of these pathogens complicates the implementation of these recommendations. Most multi-resistant pathogens are transmitted primarily by contact. Thus, transmission-free care of patients with these pathogens should be possible in double bedrooms specificially designed towards reducing these incidents. However, there are no studies on the possible equipment of double bedrooms with two bathrooms. There are also no investigations on the colonisation of new hospital buildings by microorganisms and possible influencing factors. Two questions that this project is aiming to answer.

The KARMIN project is investigating if double patient bedrooms can be upgraded as alternative to current infection prevention. As a result, a demonstrator for double bedrooms with appropriate infection prophylaxis equipment, including the wet room, was realised. 13 partners from the field’s industry were involved along with two medical research teams of the Charité Berlin and Uniklinikum Jena.

Objects optimised towards infection preventionand  methods of patient empowerment were developed and the layout of a patient room was  rethought.

The examination of the hospital microbiome during the resettlement is intended to answer the question of whether the twin room is sufficiently infection-proof for the accommodation of patients. The first occupancy of the newly renovated Charité Bettenhochhaus is the framework of the investigation. The aim is to find out what role architectural conditions (comparison of multi-bed and single rooms) and different cleaning regimes (comparison of surface disinfection and surface cleaning) play in the development and diversity of microbiomes and in the emergence of multi-resistant bacteria.

Disinfection Dispenser
The traditional disinfection dispenser faces various challenges but also poses a variety of opportunities to reduce the transmission of multirestitent bacteria. A disinfection dispenser that evokes an inductive emotional response in the user.
