In France, the overall proportion of penicillin-non-susceptible Streptococcus pneumoniae has decreased from 53% in 2002 to 38% in 2006, and the proportion of methicillin-resistant Staphylococcus aureus from 33% in 2001 to 26% in 2007. Although the rates remain very high compared to northern European countries, these trends suggest that the prevention efforts implemented since 2000 through two national programmes (the national plan for preserving the efficacy of antibiotics and the national infection control programme) and updated recommendations for pneumococcal vaccination are successful.

A Belgian Antibiotic Policy Coordination Committee (BAPCOC) was officially established in 1999 by Royal Decree. The overall objective of BAPCOC is to promote judicious use of antibiotics in humans and animals and to promote infection control and hospital hygiene, with the overall aim to reduce antibiotic resistance. BAPCOC fostered strong and interdisciplinary public health, scientific and political leadership, which led to many evidence-based interventions such as multimedia campaigns to promote the prudent use of antibiotics in the community, national campaigns to promote hand hygiene in hospitals, publication of clinical practice guidelines, staffing and technical support for establishment of antibiotic management teams in all Belgian hospitals, surveillance programmes on antibiotic use and resistance in humans and animals and the promotion of research. These activities and interventions resulted in a measurable decrease in antibiotic use and resistance in the community and hospitals.

During 1991-1999 a significant increase of consumption of macrolides and fluoroquinolones was observed in Slovenia, and this was associated with significant increase of resistance of Streptococcus pneumoniae and Streptococcus pyogenes to macrolides and Escherichia coli to fluoroquinolones, respectively. Between 1999 and 2007 the prevalence of S. pneumoniae resistant to erythromycin increased from 3.7% to 16.8% even though the use of macrolides in the same period decreased from 3.81 to 2.43 defined daily doses (DDD) per 1,000 inhabitants and per day. The co-resistance and the spread of resistant clones were the reason for constant increase in macrolide resistance. Slovenia is one of the few European countries with decreasing prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in hospital care during the last years. As a result of control measures introduced in 1999, the MRSA prevalence rates decreased from 21.4% in 2000 to 8.3% in 2007.

Repeated surveys among primary care paediatricians were performed annually from 1998 to 2002 in the Czech Republic. The task was to assess the prescription of antibiotics in treatment of respiratory infections in children. The results were evaluated in the light of existing guidelines and conclusions were used in a number of interventions aimed at reducing the inadequate use of antibiotics and hence preventing the potential increase of the antibiotic-resistant bacteria. In addition, data on overall consumption of antibiotics in outpatient care and trends in the prevalence of resistant strains of Streptococcus pneumoniae and Streptococcus pyogenes are discussed.

The overall aim of Strama (The Swedish Strategic Programme Against Antibiotic Resistance) is to preserve the effectiveness of antibiotics in humans and animals. Strama is organised at two levels: a network of independent local multidisciplinary groups in each county that provide prescribers with feedback on antibiotic use and resistance and implement guidelines; and a national executive working group funded by the government. To gain an insight into antibiotic use, Strama has conducted several large diagnosis-prescribing surveys in primary care, in the hospital settings and in nursing homes. National antibiotic susceptibility data for Sweden and mandatory notification show that in recent years the proportion of Streptococcus pneumoniae with decreased sensitivity to penicillin V has stabilised (around 6 %), but the number of notified cases of meticillin-resistant Staphylococcus aureus (MRSA) has increased and ESBL-producing Enterobacteraceae have turned into an endemic situation. Still, Sweden is among the countries with the lowest rates of MRSA (<1 %), S. pneumoniae can still be treated with penicillin V and the rate of Escherichia coli-producing ESBLs is below 5 %. Strama´s activities have contributed to a steady decrease in antibiotic use from the mid 1990s until 2004 (when total use slowly started to increase again) without measurable negative consequences. Regular collaboration with national and regional news media has been one of the key strategies.

The Dutch Working Party on Antibiotic Policy (Stichting Werkgroep AntibioticaBeleid, SWAB) was founded in 1996 as an initiative of the Society for Infectious Diseases, the Dutch Society for Medical Microbiology, and the Dutch Association of Hospital Pharmacists. Its primary goal is to contribute to the containment of antimicrobial resistance and the expanding costs incurred for the use of antibiotics. SWAB is the Intersectoral Coordinating Mechanism (ICM) for the Netherlands, and it is at present the National Antimicrobial Resistance (AMR) Focal Point. It coordinates the national surveillance of antibiotic resistance, in collaboration with the National Institute for Public Health and the Environment (RIVM), coordinates the surveillance of the use of antibiotics, and runs a guideline development programme. Information about consumption of antimicrobial agents and antimicrobial resistance among medically important bacteria is presented annually in NethMap. Over the past decade, outpatient consumption of antibiotics has risen only slightly, but in the hospital setting there was an overall significant increase in antibiotic use, due mainly to the steady reduction in the average length of patient hospital stays. In 2006 we introduced our electronic national antibiotic guide 'SWAB-ID' for the antibiotic treatment and prophylaxis of common infectious diseases in hospitals.
