Data collected and analysed by

Antibiotic resistance collects and analyses anonymous antibiotic resistance data provided by a selection of Swiss clinical microbiology laboratories (please see Organisation). Resistance data are generated during routine medical care (privacy statement).

The collected data represent at least 60% of annual hospitalisation days and at least 30% of Swiss practitioners. Epidemiological data provided allow for stratification of resistance results according to hospital versus outpatients, age groups (children!), and anatomical location. 

Antibiotic consumption

National antibiotic sales data for the years 2002 to 2006 have been purchased from  IMS Health GmbH (Hergiswil, Switzerland). Analyses have been performed and published within another NRP49 project headed by Prof. M. Filippini (Lugano, Switzerland) NRP49 . The antibiotic sales data are available for further analyses in the database.
In parallel, a long-term project has been started to collect representative antibiotic consumption data directly from a selection of Swiss pharmacies and hospitals. This will allow for the step-wise build-up of a more detailed database and analysis of antibiotic consumption. The feasibility of this project was evaluated by Prof. G. Zanetti (CHUV, Lausanne).


Bacteremia (= bacteria in the blood, = "sepsis") belongs to the most severe infections. Rapid diagnosis and treatment with an appropriate antibiotic regime is important for the survival of affected patients. Bacteremia is also one of the most frequent nosocomial infections and surveillance and prevention of nosocomial bacteremia is a primary goal of infection control. An extension of the database allowed for the inclusion and analysis of bacteremia data. Hospitals collaborating with a clinical microbiology laboratory linked with can use their own bacteremia data analysed by for internal infection control purposes.

The architecture of the database allows for future extensions to additional topics and themes.
