Welcome to the German National Reference Center for the Surveillance of Nosocomial Infections

In partnership with the Charité – University Medicine Berlin and the Institute for Environmental Medicine and Hospital Hygiene at the University Clinic Freiburg, and under the administration of the Robert Koch Institute, the National Reference Center (NRZ) for the Surveillance of Nosocomial Infections works to reduce the frequency of health care-associated infections by surveillance.

Surveillance refers to the collection and analysis of data related to health care-associated infections, and the communication of the results to relevant persons and institutions. The NRZ developed KISS (Krankenhaus-Infektions-Surveillance-System) in 1996 to standardize data collection methods in order to allow participating facilities to benchmark themselves on reference data.

KISS has since then been divided into a number of modules that consider patient risk groups, types of health care, pathogens and hand hygiene. This enables more accurate comparison of health care institutions and practices.

KISS was initially modeled on the National Healthcare Safety Network of the Centers for Disease Control and Prevention in Atlanta, USA. The CDC definitions for surgical site infections and for health-care associated infections (HAI) are used, but KISS is divided into different modules.

Among the modules are:

NEO-KISS (HAI surveillance of preterm infants in neonatology units and ICUs)

DEVICE-KISS (HAI surveillance of patients with devices such as CVCs)

ITS-KISS (HAI surveillance in ICUs)

OP-KISS (surgical site infection surveillance following certain procedures)

HAND-KISS (alcohol-based hand rub consumption surveillance)

HAND-KISS is somewhat unusual in that it does not collect data on infections but rather on a practice by health care professionals. Increasing compliance in hand hygiene (i.e., by increasing alcohol-based hand rub consumption as a surrogate parameter for compliance), however, is essential in reducing HAI frequency, and surveillance is one effective method of doing so.

For most modules, KISS participants collect data relevant to the modules they are participating in according to NRZ specifications and transfer it to the NRZ electronically with webKess, a specially developed EDP program.

Our web site is still in the process of being translated, so please check back regularly or contact the NRZ via e-mail (nrz@charite.de) if the module you are interested in is not yet available in English.
