AbstractThe transmission of multidrug-resistant organisms (MRSA, VRE and ESBL producing bacteria) occurs predominantly if health-care workers are not compliant with hand hygiene procedures. The impact of single-room isolation in transmission prevention is often overestimated. As long as hand disinfection is not performed before and after patient contact and gloves are not removed, a single room will not prevent transmission by -itself. Understaffing is additionally worsening the situation. There is no consistent evidence sup-port-ing strict single-room isolation even though data show supportive tendencies. Social isolation is one of the risks that should be considered as well as the economic impact of using shared rooms as a single room. Up-to-date, evidence-based standard operating procedures and individual infection control recommendations should take these considerations into account. In general, contact precautions including isolation in a single room are performed in MRSA and VRE-positive patients. If a single room cannot be provided in a given case (a common problem in intensive care units), contact precautions can be performed in a shared room as an alternative. The problem of establishing an optimal compliance with standard precautions (especially hand hygiene) throughout all professional groups should be addressed. Additional precautions, including single-room isolation, should be implemented critically if indicated.
