Summary

The European Antimicrobial Resistance Surveillance System (EARSS) is an international networkfunded by the Director General for Health and Consumer Protection (DG SANCO) of the EuropeanCommission and the Dutch Ministry of Health, Welfare and Sports. It maintains a comprehensivesurveillance and information system that links national networks by providing comparable andvalidated data on the prevalence and spread of major invasive bacteria with clinically andepidemiologically relevant antimicrobial resistance in Europe.

EARSS collects routinely generated antimicrobial susceptibility testing (AST) data, provides spatialtrend analyses and makes up-to-date feedback available via an interactive Website athttp://www.earss.rivm.nl. Over 700 laboratories serving 1100 hospitals in 28 European countriesregularly submit routine data for major indicator pathogens (Streptococcus pneumoniae,Staphylococcus aureus, Enterococcus faecalis, Enterococcus faecium, and Escherichia coli). On thebasis of the 2002 laboratory/hospital questionnaire, the overall hospital catchment population of theEARSS network is estimated at more than 100 million inhabitants in the European region, withnational coverage rates that range between 20% and 100% for individual countries. In 2002, 93% ofthe eligible laboratories also participated in the annual external quality assurance (EQA) exercise,which is jointly organised by EARSS, the United Kingdom External Quality Assurance Scheme (UK-NEQAS) and the Centre Réfèrence des Antibiotiques (CRAB). Despite the different guidelines usedin various countries, the overall concordance of susceptibility results was of sufficient quality, whichshows that pooling and analysis of EARSS surveillance data render valid results for most pathogen-specific susceptibility data.

For the last 4 years, the resistance showed a clear north–south gradient for penicillin non-susceptibleS. pneumoniae (PNSP), with high levels of macrolide co-resistance in several of the southern andthe northern countries. The dynamics of the global epidemic of methicillin-restistant S. aureus(MRSA) has slowed down in the United Kingdom and Ireland, but it showed the fastest increasingproportions in Germany and Austria between 1999 and 2002. Scandinavian countries have beenspared from this trend, but the Netherlands saw the beginning of a trend towards higher MRSA ratesin 2002. Vancomycin-resistant enterococci (VRE), with proportions less than 10% in most countries,have been reported. The six countries that reported higher rates of VRE also had large MRSAproportions, which suggests an epidemiological association. E. coli resistance to theaminopenicillins is common in the European region; only Finland and Sweden report proportions ofless than 30%. Resistance of E. coli to third-generation cephalosporins remained less than 6% inmost countries. Greater proportions were noted for some eastern European countries that appearedto have problems with extended spectrum beta-lactamase (ESBL)-producing strains. However, therewas a consistent and marked rise in fluoroquinolone-resistant E. coli in most European countries,eight of which witnessed an 1.5-fold increase or more in only 2 years (2001 – 2002). This trend mayto be related to the widespread acceptance and use of newer fluoroquinolones with enhanced activityagainst gram-positive pathogens. We predict that both hospital and community-acquired E. coliinfection may become a new challenge as a pathogen that will be difficult to treat in the Europeanregion in the years to come.

EARSS has become an internationally accepted surveillance initiative, which provides meaningfulinformation about the status and trends of antimicrobial resistance in the European region. Thepossible relationship between antimicrobial resistance and consumption will be explored in close

cooperation with European Surveillance of Antimicrobial Consumption (ESAC). We envisionEARSS serving as a platform for the detection and identification of clones with particularimportance to public health in terms of antimicrobial resistance and virulence properties.

The EARSS 2002 annual report would not have been possible without the financial support of DGSANCO of the European Commission (SI2.324194/2001CVG4 – 011) and the Dutch Ministry ofHealth, Welfare and Sports.

CHAPTER 1. Introduction

Antimicrobial resistance (AMR) challenges the effectiveness of successful treatment of bacterialinfections and is a public health issue with local, national and international dimensions. During the‘Microbial Threat Conference’, held in September 1998 in Denmark, it was announced that‘Effective European surveillance must have the agreement and active involvement of allparticipants’ (‘the Copenhagen Recommendations’ [1]). In due course, the Directorate General forHealth and Consumer Protection (DG SANCO) of the European Commission funded the EuropeanAntimicrobial Resistance Surveillance System (EARSS). EARSS’ mission is to maintain acomprehensive surveillance and information system that links national networks by providingcomparable and validated data about the prevalence and spread of major invasive bacteria withclinical and epidemiologically relevant AMR in Europe. In 2001, at a follow-up EU conference inVisby, Sweden, it was concluded that all Member States of the European Union (EU) should join theEARSS initiative as a minimum requirement of national surveillance programmes (‘the Visbyrecommendations [2]’).

EARSS is co-ordinated by the Dutch National Institute of Public Health and the Environment(RIVM), and since its beginning in 1999, it has steadily drawn in new participants from theEuropean countries. At present, around 700 laboratories serving almost 1100 hospitals in 28European countries participate. They cover an estimated population of more than 100 millioninhabitants. The EARSS database contains AMR data on approximately 120 000 invasive isolates offour genera (Streptococcus pneumoniae, Staphylococcus aureus, Enterococcus faecalis/faecium, andEscherichia coli). It is thus the most comprehensive public health effort that describes and analysesgeographic and secular trends in AMR worldwide.

EARSS has encouraged and helped sustain national surveillance efforts, and the network is theperfect basis for an integrated public health approach for AMR containment in Europe. To this end,EARSS operates in close collaboration with other EU- financed projects: European Surveillance ofAntimicrobial Consumption (ESAC), Self-medication with Antibiotics and Resistance (SAR) andAntibiotic Resistance Surveillance and Control in the Mediterranean region (ARMed). There is aclose partnership between the European Society of Clinical Microbiology and Infectious Diseases(ESCMID) and two of the society’s study groups, namely, the European Committee onAntimicrobial Susceptibility Testing (EUCAST) and the ESCMID Study Group for AntimicrobialResistance Surveillance (ESGARS).

This report presents an overview of activities, innovations and results of the EARSS network.Chapter 2 summarises the objectives and methodology. Chapters 3 and 4 present reference dataregarding the participating laboratories and hospitals and the results of the annual EQA exercise forthe year 2002. Chapter 5 gives an in-depth analysis on the situation of AMR in the European region.Chapter 6 provides recommendations and lists possible future initiatives based on these results. Theappendixes contain detailed country summary sheets, tables with data and a technical section.Results are based on data recorded from January 1999 - December 2002, if not otherwise indicated.

CHAPTER 2. The EARRS objectives and methodology

The objectives

It is the public health purpose of EARSS to assist in the control of AMR; therefore, the followingobjectives have been set:• To collect comparable and validated AMR data • To analyse trends in time and place (among various European countries) • To provide official national AMR data that constitute a basis for policy decisions• To provide feedback to ‘those who need to know’• To provide information about clinically and epidemiologically relevant AMR and to evaluate

interventions.

Furthermore, EARSS aims are:• To encourage the implementation, maintenance and improvement of national AMR surveillance

programmes to provide timely information for national policy decisions• To link AMR data to factors influencing the emergence and spread of AMR, particularly to

antibiotic use data, in close cooperation with the European Surveillance of AntimicrobialConsumption (ESAC)

• To initiate, foster and complement scientific research in Europe in the field of AMR.

At the start of the project, the task determined for EARSS was to collect routinely generatedantimicrobial susceptibility testing (AST) data from a limited number of invasive pathogens. Thepathogens that successively became objects of surveillance within EARSS were selected accordingto epidemiological (community versus hospital acquisition) and ecological (transmission versusselection) paradigms. At the same time, the focus was set on selected clinically andepidemiologically relevant antibiotic resistance traits. The decision to collect routine data meant thatno changes to the regular diagnostic process were needed. Therefore, the participation of manylaboratories has become feasible, and this has facilitated the probing of a substantial part of thepopulation in the participating countries. Sampling of the pathogens was and is restricted to invasive(blood culture and CSF) isolates, which are routinely tested for antimicrobial susceptibility in mostlaboratories. Data collection started in 1999 for S. pneumoniae and S. aureus after a preparatoryphase in 1998. The surveillance has been extended to include E. coli and enterococci (E. faeciumand E. faecalis since 2001).

The methodology

Organisation of the EARSS networkEach participating country has appointed one or two national representatives. They are medicalmicrobiologists and/or infectious disease epidemiologists. Moreover, each country has a national datamanager. The main task of the national representatives is to connect the EARSS-specific activities ofthe participating laboratories (data collection, reporting, questionnaire completion and EQA strain andresults distribution) with the EARSS central database, which is maintained and updated by the EARSSManagement Team (EARSS-MT). The national representatives also ensure that the laboratoriesgenerate their AST data according to the EARSS protocols, as published in the 2001 EARSS manual.

CHAPTER 2. The EARSS objectives and methodology 17

The main task of the national data manager is to collect, approve and forward resistance data eachquarter and to assist the national representative. Protocols for standardising the data collection havebeen developed with professional help from the European Society of Clinical Microbiology andInfectious Diseases (ESCMID) and WHO microbiology laboratory database software (WHONET).To assess the quality and comparability of AST data, an EQA exercise is carried out every year incollaboration with the UK-NEQAS and the Centre National de Réfèrence des Antibiotiques(CRAB). EARSS contributes to the global strategy established by the World Health Organization(WHO) for worldwide surveillance of drug resistance.

The national networksIt is the task of the national representatives to select participating laboratories/hospitals that cover atleast 20% of the total population. The various types of hospitals (university or tertiary care hospitals,general or district hospitals, rehabilitation centres or nursing homes, and others), the differentgeographic regions (urban/rural), and the socio-economic strata should be represented as well aspossible.

We collected reference information on the national networks with the 2002 laboratory/hospitalquestionnaire. This questionnaire served three main purposes:1. To collect denominator information for the estimation of incidence rates, i.e. the frequency with

which resistant bacteria were ascertained in a population. Unlike resistance proportions,incidence rates may improve comparisons between hospitals, regions and countries.

2. To collect information about the representativeness of EARSS results to understand whether thereported data should only be applied to regions or whether they can be generalised at the countrylevel.

3. To explore existing efforts and the potential interest among participating centres in improving aninfrastructure for the identification of clones with particular public health importance.

Collecting and processing antimicrobial susceptibility testing (AST) dataEARSS routinely collects susceptibility test results of invasive isolates and background informationabout patients. Laboratories are asked only to report the first isolate from blood or cerebrospinalfluid (CSF). According to the specifications of the EARSS exchange format (2001 EARSS manual),the system requires the laboratory code, isolate sample number, isolate source, date of samplecollection, sex, month and year of birth, hospital code, hospital department, origin of patient (levelof care – ambulant, hospitalised, etc.), and the pathogen and antibiotic susceptibility testing resultsas specified in the protocols. Furthermore, optional data are collected; they include clinicaldiagnosis, other conditions, and susceptibility data for other antibiotics.

LaboratoriesParticipating laboratories can opt for one of two ways of submitting data: by e-mail or by sendingin conventional isolate record forms (paper). EARSS provides various free software tools forelectronic data handling, downloadable from the Website at www.earss.rivm.nl: (1) WHONET, themicrobiology laboratory software, revised for EARSS by John Stelling, and (2) Data Entry &Feedback Software (DEFS), which was developed especially for EARSS. Laboratories are asked tocollect AST data on a routine basis and to forward them to the national representative or datamanager quarterly. Before submission, laboratories are asked to check their data for: • Adherence to the EARSS protocol• Microbiological consistency/plausibility• Consistency with clinical sensitive (S), intermediate (I) and resistant (R) breakpoints as defined

by to the guideline used.

National representative and national data managerAt the national level, the national data manager, in consultation with the national representative,processes the data. This is done in a stepwise procedure by:• Recording data from all participating laboratories.• Manual data entry if isolate record forms are used. • Merging data from all participating laboratories into one single file.• Removing duplicate reports. Only primary isolates per patient per quarter shall be reported. • Converting data to EARSS exchange format (2001 EARSS manual). • Revising data with the Data Check and Feedback Programme (DCFP)• Approval of data by the national representative (adherence to EARSS protocol, check for

microbiological consistency, and check whether the S, I and R interpretations agree with theminimal inhibitory concentrations (MICs) reported.

• Data transfer to EARSS-MT on a quarterly basis.

Feedback from EARSSAccurate and timely feedback is essential for surveillance systems. Once they are made available toEARSS-MT, data are analysed and returned in a standard feedback report to the nationalrepresentative. This feedback contains information on pathogens with important and unusual

CHAPTER 2. The EARSS objectives and methodology 19

resistance patterns (MRSA, PNSP, VRE), and contains information on the validity and completenessof the data. Subsequently, the national representative is asked to confirm the correctness of theresults. With his/her approval, the data will be added to the EARSS database and will becomeimmediately available on the interactive EARSS Website at www.earss.rivm.nl, where they can beaccessed in various formats, such as tables, figures, and geographical maps.

Furthermore, the data from the EARSS database are used to prepare annual reports, newsletters andpublications that are disseminated to the participants, policy makers and a broader public.

CHAPTER 3. Results of the EARSS 2002 laboratory/hospital questionnaire

Introduction

EARSS regularly receives routine AST results from approximately 700 laboratories in 28 Europeancountries. Reference information about the populations for which these laboratories provide theirservices is essential for understanding the validity, i.e. representativeness and generalisability, ofEARSS data. A good to fair representation of the country’s situation with respect to antibioticresistance is needed to justify comparisons with other countries and to present sensible results. Toachieve this degree of comparability, EARSS aims to collect information on AST results forpopulations that:• Comprise at least 20% of the total national population• Represent the different geographical and socio-economic strata• Receive treatment in different types of hospitals (university hospital/tertiary care, district

hospital/general care, and long-term care/other).

In May 2003, the EARSS 2002 laboratory/hospital questionnaire was sent to all laboratoriesparticipating in EARSS to collect information on the number and types of hospitals they serve, thecatchment population, size and occupancy rate of these institutions, and the frequency of bacterialblood culture tests. The questionnaire also included eight questions about existing strain (clone)identification systems (typing) and explored the interest of participating laboratories in contributingto an international initiative for strain identification.

The EARSS-MT distributed the questionnaires to the national representatives, who forwarded themto the participating laboratories. The information was required for the year 2002 only. Completedquestionnaires were returned to the national representatives, who forwarded the information to theEARSS-MT. The EARSS-MT set up a database and carried out the descriptive analysis. Details ofthe data analysis are given in the technical notes (Appendix B).

In this chapter, preliminary results of this exercise are presented and discussed. Detailed results foreach country are also presented in the country summary sheets (Table 1, Figures 1 and 2 of AppendixA). More extensive and final information will be made available early next year.

Results and discussion

Participation This preliminary investigation includes countries, laboratories and hospitals for which bothdenominator data and AST results were available for 2002. In total, 306 of the 600 laboratories(51%) and 416 of the 837 hospitals (50%) from 21 of the 27 countries that reported AST data toEARSS in 2002 responded to the EARSS 2002 questionnaire (Figure 3.1). Three additionalcountries (Austria, Denmark and Ireland) reported aggregated data, which unfortunately could notbe included in laboratory/hospital-specific analysis. However, the data provided by these countriesare included in Appendix A (country summary sheets).

countries. Almost complete coverage (> 90%) was achieved by eight of the 21 countries (Table 3.1).The population coverage appears to be overestimated for some countries, possibly due tooverlapping catchment populations. This error may occur when hospitals are located within eachother’s vicinities and therefore draw patients from partly identical populations. The estimatedcoverage of the total population was less than 20% for Spain (19%), Portugal (18%) and the UnitedKingdom (16%). However, this underestimates the real coverage achieved by EARSS in thesecountries, as catchment population data were not available for all participating hospitals. Thecoverage would most likely have exceeded 20% if all hospitals participating in EARSS had beenincluded.

Hospital informationFigure 3.2 shows that secondary and tertiary care facilities in all countries except Malta wererepresented. (Malta has only one public hospital, which provides both tertiary and secondary care).The proportion of tertiary versus secondary care varied substantially among countries, which mayresult in differences in case mix and may confound comparison of country AST results. However,the definition of secondary and tertiary care may also vary from country to country, and assigningunambiguous and comparable care levels to hospitals in various countries is presently not easilyachieved.

The average annual occupancy of hospitals was about 80% in most countries, and it varied from 61%(the Netherlands) to 97% (Israel). Table 3.2 gives information on the hospitals providingdenominator data. In most of the countries, at least one hospital with a burn unit and/or facilities thatcarry out solid organ/bone marrow transplantation reported to EARSS. The proportion of ICU bedsvaried between 1.9% (Poland) and 8.6% (Czech Republic). Hospitals that care for burns, forimmunocompromised patients or for those who have had complex surgery are usually faced withmore infections requiring antibiotic treatment and consequently witness higher resistance rates.Indeed, the incidences of MRSA and VRE were greater in hospitals performing complex operations(1.5 versus 6.2 MRSA infections per 100 000 patient days, and 0.04 versus 0.2 VRE infections per100 000 patient days, respectively; P < 0.05).

Blood culture practice As becomes clear from Tables 3.1 (number of blood culture sets per 100 000 inhabitants) and 3.2(number of blood culture sets/1000 patient days), blood culturing practices vary among countries,which was also shown by others [1,2]. The sampling frequency for blood cultures may bias the ratesof ascertaining blood stream infections. Variation in the numbers of blood culture sets per 100 000inhabitants and per 1000 patient days suggests different practices in eastern and western Europe.Relatively high rates (> 20 sets/1000 patient days) were reported by Spain, Finland, Israel,Luxembourg, the Netherlands, Portugal, Sweden and the United Kingdom, whereas rates of less than15 sets/1000 patient days were calculated for the other countries listed in Table 3.2, which weremainly eastern European countries. Israel had much higher blood culturing rates than any othercountry. Similar patterns exist for the number of blood culture sets/100 000 inhabitants (Table 3.1).However, it is not expected that these differences in blood culture practice influence the comparisonof AMRs, as reported resistance proportions were independent of blood culture frequencies.

Incidence rates of nosocomial blood stream infectionsTable 3.3 shows the incidence of MRSA and VRE blood stream infections. In general, incidencerates are more relevant than resistance proportions as they provide patient-based risk estimates ofacquiring such blood stream infections in the respective national hospital care system. However, incomparisons of incidence rates with resistance proportions, the ranking order by country remains byand large unchanged as regards MRSA. This is a clear indication that EARSS resistance proportionsare good approximations of the incidence rates, and they supply useful information for comparingcountry-specific resistance rates. Thus, the MRSA and VRE ranking order remains basicallyunchanged (Chapter 5). There was little VRE incidence in most countries. However, confidenceintervals were large because few E. faecium isolates were reported. This is reflected in the relativelyhigh detection limits shown in Table 3.3. The highest rates were established for participatinghospitals in Israel and Croatia.

Laboratory information: typingMost laboratories would welcome a standardised typing approach, a standardised nomenclature, anda typing network for the identification of the emergence and spread of ‘EARSS-specific’ pathogensin their countries. More laboratories were interested in such services for S. aureus and S. pneumoniae(98%) than for E. faecium and E. coli (93%). Almost all laboratories (298 of 301; 98%) wouldwelcome a common database that could be queried for the existence, distribution and prevalence ofbacterial strains with important public health relevance (high resistance or virulence) in theEuropean region.

Conclusion

The EARSS 2002 laboratory/hospital questionnaire provided necessary insights into thedenominator population and sampling practice of the participating laboratories and hospitals. It wasa useful instrument for identifying the scope for future initiatives within the EARSS network. On asample basis (21 of 28 countries), it could be shown that EARSS supplies representative and robustantimicrobial susceptibility data for European countries. The population coverage is adequate andgreater than 20% for most participant countries. Individual countries still differ in definition andcomposition of tertiary and secondary care hospitals, which may introduce some minor flaws ininternal validity. Some countries could improve the geographical spread of EARSS laboratories byinclusion of hospitals in areas that are not yet well represented (see country maps in the countrysummary sheets). In comparisons of incidence rates with resistance proportions, the overall rankingorder by country remained unchanged. This indicates that EARSS resistance proportions representmeaningful data and undoubtedly supply useful information for comparing country-specificresistance rates. Moreover, EARSS participants would welcome standardised and internationaltyping approaches for the identification of bacterial strains with particular public health importance.

CHAPTER 4. Quality and comparability of antimicrobialsusceptibility testing (AST) among laboratoriesparticipating in EARSS in 2002

Introduction

The differences in methods and national guidelines among European laboratories may affect thecomparability of interpretative results based on clinical breakpoints. It is therefore indispensable thatlaboratories participate in EQA schemes . In 2002 EARSS organised the third EQA exercise. Its aimwas to assess the quality and comparability of susceptibility results across countries and to comparethe results with respect to country-specific guidelines. This exercise is also crucial for determiningwhether pooling and analysing the routinely collected antimicrobial surveillance data within theEARSS network generates valid results.

Methods

In September 2002, UK-NEQAS distributed a set of five strains to the laboratories participating inEARSS; S. aureus U2A1556, E. faecium U2A805, E. coli U2A1557, E. coli U2A1526 and S.pneumoniae U2A1580, which were provided by CRAB. The laboratories were requested to reportmethods and guidelines used for species identification, MIC determination (when performed) andclinical susceptibility breakpoints (S, I and R). Results were considered ‘concordant’ if the reportedcategorisation (S, I or R) agreed with the interpretation independently approved by three referencelaboratories.

Results and discussionThe offer of participation in the EQA was readily taken up by 642 of the 690 laboratories (93%) in26 countries (Figure 4.1).

The high response rate for this third successive EQA shows that the interest among laboratories tocompare their results with international standards has not abated (90% response rate in 2000, 91%in 2001 and 93% in 2002) and shows a continuous commitment to quality.

Table 4.1 displays the different guidelines used by the laboratories of the various countries andshows that most of the laboratories have adopted (American) National Committee for ClinicalLaboratory Standards (NCCLS) guidelines (71%).

As Table 4.2 shows, the overall concordance of susceptibility results was excellent and matched theintended results. This indicates that the routine susceptibility testing in the laboratories participatingin EARSS is extremely satisfactory. The results also show that the EARSS pooling and subsequentanalysis of the resistance surveillance data renders valid results for most of the pathogen-specificsusceptibility data. However, there is room for improvement.

The majority of laboratories identified the five distributed strains correctly at the species level. Asingle strain (E. faecium U2A 805) was misidentified by 79 (13%) of the 627 laboratories. In mostof these cases (n = 55), it was identified as an E. casseliflavus or E. gallinarum.

reaction are occasionally unable to distinguish accurately between E. faecium and other enterococciof the gallinarum group. Additional testing for motility and pigmentation can discriminate morereliably. This 13% misidentification of the E. faecium strain should alert the respective laboratoriesto potential uncertainties in their speciation.

The oxacillin/methicillin resistance in S. aureus U2A1556 (mecA+ve) was not detected by 6% andthe resistance to vancomycin in E. faecium U2A805 was not noticed by 10% of the participatinglaboratories. Considering the clinical, epidemiological, and infection control implications associatedwith such strains, it appears critical to improve the identification of these relevant resistancephenotypes.

The relatively low concordance in determining ciprofloxacin susceptibility in S. pneumoniaeU2A1580 can be explained by the facts that (1) the British Society for Antimicrobial Chemotherapy(BSAC) and Swedish Reference Group for Antibiotics (SRGA) guidelines recommend alwaysreporting a ciprofloxacin test as I or R for S. pneumoniae and (2) some guidelines (e.g. NCCLS, orComité de l’Ántibiogramme de la Société Française de Microbiologie(CA-SFM)) do not give anyrecommendations at all. This example illustrates that breakpoints may differ substantially for somedrug-bug combinations. In these cases, data interpreted (S, I, R) by the various countries should becompared with caution. Therefore, EARSS strongly supports the EUCAST initiative to defineuniversal epidemiological breakpoints based on wild-type distributions for surveillance.

A complete and detailed report of the 2002 EQA results was distributed to all EARSS participantsin March 2003.

Conclusion

Despite the adherence to different guidelines by countries reporting to EARSS, most of thesusceptibility results were concordant. This finding underlines the facts that the overall comparisonof routine results generated in different laboratories throughout Europe is feasible for the species andantibiotics tested.

CHAPTER 5. The antimicrobial resistance (AMR) situation inEurope in 2002

Introduction

Approximately 10% of the entire burden of disease in European countries (which include new andold member states of the European Community) can be attributed to infectious diseases. Thiscontrasts to many Asian, South American and African countries where 42% to 71% of the entiredisease burden is caused by communicable diseases [1]. The smaller proportion attributable to thegroup of communicable diseases in Europe is the result of numerous economical and socialdevelopments that have led to improvements in public health and clinical services. These include theavailability of successful antimicrobial therapy, which is an important factor. In contrast to otherpharmaceutical interventions, however, antibiotic treatment has a societal effect, as selection forresistant pathogens is not confined to the individual receiving treatment, but by nature of theinfectious agents can expand into the community at large. It is this feature that makes AMR a healthissue for both clinical services and public health programmes.

During the last 4 years (1999–2002), EARSS has collected routine resistance data about diseaseisolates of S. pneumoniae (n = 22 244), S. aureus (n = 53 264), E. coli (n = 35 565) and E.faecium/faecalis (n = 9463). The EARSS database contained data on 120 536 isolates from some 700laboratories serving around 1100 hospitals in 28 countries at the end of 2002. This chapter discussesthe current dimension and pertinent trends concerning AMR as related to the pathogens just mentionedfor the European region. Appendix A provides summary statistics for individual countries.

Results and discussion

Streptococcus pneumoniae Streptococcus pneumoniae is the single most important cause of infections of the lower respiratorytract (such as pneumonia) in adults and children. It is also the main cause of otitis media in childrenand causes life-threatening meningitis in children and the elderly. Penicillin and other beta-lactamantibiotics have been the mainstay of antipneumococcal therapy since the 1940s. However, a steadydecrease of penicillin susceptibility has been reported from many countries worldwide in the pasttwo decades.

In 2002, the EARSS network identified the largest proportions of penicillin non-susceptible S.pneumoniae (PNSP, > 25%) in France, Israel, Poland, Romania and Spain. The smallest proportionsof PNSP were reported from the north of Europe, but also from more central European countriessuch as Germany and Austria (Figure 5.1; Table 1 of Appendix C).

Even though the average proportion of PNSP was 11% for all the isolates reported in 2002, (Table1 of Appendix C), the average proportion of isolates fully resistant (MIC ≥ 2 mg/L) to penicillin wasonly 2%. However, large variations in the proportion of PNSP, from <1% in Estonia and Malta to53% in France (Table 1 of Appendix C) and variations in the proportion of fully penicillin resistantisolates, which ranged between 0% and 10% (Spain), were found between countries. So far, there isno evidence of bacteriological failure of penicillins active against intermediate susceptible strains[2]. This means that pneumococcal infections other than meningitis should still respond to high oralor intravenous doses of amoxicillin or high intravenous doses of penicillin.

The frequency with which PNSP was reported to EARSS during the last 4 years remained relativelystable for most of the countries (Austria, Belgium, Germany, Spain, Italy, the Netherlands, Swedenand the United Kingdom), and showed an increase for the Czech Republic and Finland. In addition,a decrease was observed for Slovenia and Ireland (P < 0.05). Due to the small sample size ofisolates, no conclusions concerning trends over time could be drawn for Bulgaria, Iceland,Luxembourg and Malta (Figure 5.2).

EARSS identified a clear predominance of erythromycin non-susceptible isolates (ENSP) insouthwestern countries in 2002 (Figure 5.3). The greatest proportions of ENSP were found inBelgium (34%), France (58%) and Italy (32%) and the smallest proportions of ENSP (≤ 5%) wereobserved in the Czech Republic (4%), Denmark (5%), Estonia (0%), and Iceland (5%). Among theScandinavian countries, only Finland showed a steady increase in reduced erythromycinsusceptibility from 6% in 1999 to 13% in 2002 (Table 1 of Appendix C).

Figure 5.4 shows that a large part of the penicillin non-susceptible S. pneumoniae isolates are alsoresistant to erythromycin in most countries. In fact, co-resistance is of dual public health importance.Not only does it affect the clinical management of infections, co-resistance also means that each ofthe antibiotic substances to which a pathogen has developed resistance independently facilitates thesuccess of co-resistant clones.

Staphylococcus aureus Staphylococcus aureus is the main cause of bone, joint and soft-tissue infections acquired in hospitaland in the community. It also causes blood stream infections and endocarditis, and it is a frequentcause of food poisoning. S. aureus resistant to penicillinase-fast beta-lactam antibiotics such asmethicillin, oxacillin, cloxacillin, flucloxacillin, nafcillin and cephalosporins is commonly termedMRSA (for methicillin-resistant S. aureus). S. aureus has become a notorious cause of hospital-acquired infections and thrives in hospitals worldwide. Due to the multiresistant nature of MRSA,glycopeptide antibiotics (vancomycin and teicoplanin) with inferior pharmacokinetic propertieshave become the treatment of choice. In the last decade, there have been repeated reports of newlyemerging MRSA strains that cause difficult-to-treat community-acquired skin infections in theUnited States.

Figure 5.5 displays the current proportions of MRSA in various European countries (Table 1 ofAppendix C). The reason why MRSA enjoys such heterogeneous success in Europe with resistanceproportions that vary 100-fold between countries is multifaceted. Successful epidemic clonesquickly exploit ecological opportunities. Any combination of a wide range of factors, such asincreased colonisation pressure brought about by imported cases, a habitual prescribing of antibioticsin health care facilities, obstruction of early detection, inappropriate isolation precautions, patientcrowding, low staff-patient ratios and reduction in basic housekeeping performance can account forthe rapid spread of MRSA through regional or national health care systems.

There has been a significant increase of MRSA (P < 0.05) in Austria, Belgium, Germany, and theUnited Kingdom (Figure 5.6) during the last 4 years. Germany and Austria witnessed the quickestexpansion: from 8% to 19% and from 5% to 11%, respectively. The United Kingdom and Irelandcurrently see more of a stabilisation of the fast rise that characterised the increase of MRSAthroughout the 1990s in the British Isles, and they have maintained levels below 45% in the last 2years (2001 and 2002). The only consistent decrease was reported by Slovenia (from 21% in 2000to 14% in 2002, P < 0.05), where public debate following a national prevalence study resulted inincreased awareness and nationwide education efforts for doctors in 2001. It appears that thesemeasures had the desired effect and brought MRSA rates down in 2002 for the second successiveyear. In northern countries – Iceland, Denmark, Sweden, Finland and the Netherlands – theproportion of MRSA remained less than 1%. Nonetheless, the Netherlands saw a slight, butsignificant, increase in 2002 over the previous years (Figure 5.6).

EnterococciAlthough not as virulent as the other indicator pathogens recorded by the EARSS initiative,enterococci are common causes of urinary tract infections and a frequent component of intra-abdominal infections. They cause severe forms of endocarditis, and are hideous, opportunisticpathogens in immunocompromised patients, where they cause septicaemia, meningitis and boneinfections. By nature relatively resistant to many antibiotics, enterococci were the first significanthuman pathogens that reportedly developed resistance against third-line glycopeptide antibiotics(vancomycin and teicoplanin). Ever since, vancomycin-resistant enterococci (VRE) have served asa paradigm for the post-anti-microbial era [3].

The proportion of vancomycin-resistant E. faecium was reported above 10% in Ireland, Italy,Greece, Croatia, and Romania in 2002, and it was between 5% and 10% in Germany, Austria, CzechRepublic and Israel (Figure 5.7; Table 1 of Appendix C). However, the European picture isincomplete since EARSS does not yet receive data from Belgium, Denmark, Norway and the UnitedKingdom, and very few isolates (< 10) were reported by Iceland, Romania and Slovakia.

High-level aminoglycoside-resistant E. faecalis appeared frequently in the European region in 2002.Only Iceland reported a proportion of isolates less than 10%, and, for a few countries – Austria,Finland, France, Luxembourg and Malta – the proportion was less than 20%. Bulgaria, Greece, andHungary reported the largest proportions of high-level aminoglycoside resistance (Figure 5.8; Table1 of Appendix C).

Trends in resistance of hospital-acquired infections The proportions of MRSA and VRE in 2002 are combined by country in Figure 5.9. Six countriesreported epidemic proportions of VRE (≥ 10%). All of them belong to the nine countries that alsoreported the highest MRSA rates (> 35%). This suggests an intricate relation between MRSA andVRE, which is most likely twofold. Empirical treatment decisions in situations where MRSA thriveswill frequently give preference to glycopeptide antibiotics and thereby bring about conditions thatfavour the selection for glycopeptide-resistant enterococci. At the same time, the dissemination ofthese predominantly nosocomial pathogens is supported by common ecological forces. The co-circulation of these pathogens in the same populations is a reason for concern, as is highlighted byrecent reports of fully vancomycin-resistant MRSA (VRSA) in the USA, where co-infection ofpatients with both VRE and MRSA led to conjugative transposition of the vancomycin resistancegenes from VRE to MRSA [4].

Escherichia coliEscherichia coli is the most frequent gram-negative rod isolated from blood cultures in clinicalsettings. It is the most frequent cause of community and hospital-acquired urinary tract infections; itis associated with spontaneous and surgical peritonitis; it causes synergistic wound infections; andit is one of the most important food-borne pathogens. Broad-spectrum penicillins such as ampicillinand amoxicillin were the treatments of choice before beta-lactamases (mostly plasmid coded TEM1)became an almost ubiquitous component of the genetic equipment of this species. Except forSweden and Finland, the proportion of E. coli isolates resistant to aminopenicillins was largest than30% for all countries (Figure 5.10; Table 2 of Appendix C).

Figure 5.10. Escherichia coli: invasive isolates resistant to aminopenicillins in 2002

In most European countries, the proportions of isolates resistant to third-generation cephalosporinsremained at 6% or less in 2002. The greatest proportions of third-generation cephalosporinresistance were found among some of the eastern European countries: Bulgaria (13%), Israel (8%)and Romania (18%, Figure 5.11; Table 2 of Appendix C). Despite overall small proportions, thereis no reason for complacency, since resistance to third-generation cephalosporins in E. coli isbrought about by extremely successful, extended-spectrum beta-lactamases (ESBLs). Theseresistance determinates are plasmid-coded and easily spread by conjugation, not only amongdifferent strains of E. coli but also among different species of enterobacteriaceae. ESBLs arepotentially a serious impediment to the treatment of community and hospital E. coli infections inEurope.

As shown in Figure 5.12, most European countries have attained proportions of fluoroquinoloneresistance of 10% or greater in 2002 (Table 2 of Appendix C). Within the 2 years since EARSSstarted AMR surveillance for E. coli, 21 countries have provided complete AST data. Sixteen ofthem witnessed an increase in fluoroquinolone resistance (Figure 5.13) and eight countries sawfluoroquinolone resistance in 2002 increase to 1.5 times the resistance rates reported in 2001 ormore. The consistency of this finding reflects a worrying trend and might be the consequence of thewidespread acceptance and use of newer fluoroquinolones with enhanced activity against Gram-positive pathogens as a convenient alternative to other broad-spectrum antibiotics.

Figure 5.13. Escherichia coli: invasive isolates resistant to fluoroquinolones by country in 2001 and 2002

Similar to third-generation cephalosporin resistance, the greatest proportions of gentamicin andtobramycin resistance were found in eastern European countries, namely, Bulgaria , Romania andIsrael (>15%). They were still less than 1% in Finland and Sweden (Figure 5.14; Table 2 ofAppendix C). The greater resistance proportions in eastern Europe can be attributed to the frequentadministration of this antibiotic class in clinical settings. Aminoglycosides remain an inexpensivealternative to other injectable drugs and are still employed as a single drug therapy in manyhospitals.

E. coli isolates with multiple resistance to third-generation cephalosporins, fluoroquinolones andaminoglycosides are still scarce in Europe (0.74% for the period 1999–2002) and only occurred inBulgaria (14/211; 7%), Israel (85/1569; 5%) and Romania (4/26; 15%) in greater proportions.

Conclusion

During the last 4 years, resistance proportions for S. pneumoniae have remained relatively stable inthe European region with high rates of PNSP in France, Spain, Poland and Romania and low levelsin northern and central parts of Europe. However, the proportions increased in Finland and the CzechRepublic. The alternative treatment with macrolides favoured in many countries has led to greatresistance in France, Spain, Italy, Belgium and Slovakia. The combined loss of susceptibility to bothpenicillins and macrolides (co-resistance) may also become a growing issue in these countries. Sincethere is increasing evidence of macrolide failure in pneumococci if the MICs are 4mg/L or greater,high-dose treatment with beta-lactam antibiotics remains the saver treatment alternative in countrieswhere most PNSPs are of intermediate susceptibility.

For MRSA, the dynamics of the global epidemic has slowed down in the United Kingdom andIreland, whereas Germany and Austria showed the quickest increase of MRSA rates between 1999and 2002. Scandinavian countries are still spared from this trend, but the Netherlands saw thebeginning of an increase in 2002. The proportions of vancomcyin-resistant enterococci haveremained small in most countries; however, a few reported large proportions. In all of them, MRSAthrives and VRE outbreaks in hospitals are certainly favoured by increased glycopeptideconsumption. To control such outbreaks, it is incumbent to set up infection control procedures andrevise the guidelines for empirical glycopeptide use.

Of all “EARSS-specific” pathogens, E. coli showed the most worrying trends. Not only have beta-lactamases become a constitutive genetic component of more than 50% of all invasive isolates(rendering these strains resistant to ampicillin/amoxcicillin), but there was also a marked andconsistent increase in fluoroquinolone resistance in most countries (16 of 21) that reported E. colisusceptibility data to EARSS. At the same time, third-generation cephalosporins have lost more andmore of their activity in countries where ESBL-producing strains are on the rise. Community andhospital E. coli infections are likely to become increasingly difficult to treat and may pose a healththreat to patients in the European region.

CHAPTER 6. Conclusions and future initiatives

Geographic variation in the proportions of antibiotic resistance in Europe has been a consistentpattern over the years, and it seems to reflect the ecological differences encountered by the ‘EARSS-specific’ pathogens in various countries. To understand the driving forces behind this disparity,EARSS did some original analysis and was able to correlate beta-lactam antibiotic consumption withpenicillin-non-susceptible S. pneumoniae (PNSP) for the EARSS participating countries in 2001 [1].Since most of the PNSP isolates belong to eight frequently occurring serotypes and mainly originatefrom infections of infants and toddlers, there is hope that invasive disease caused by resistant strainscould be controlled by conjugate vaccines that have recently been made available. It is incumbent,however, to monitor the serotype distribution among invasive and resistant isolates once vaccinesbecome widely accepted. EARSS laboratories would be ideally suited to provide these services aswell as to determine the population effectiveness of such an intervention.

The largest variation in resistance proportions in the European region was observed for MRSA, andit became apparent that the global MRSA epidemic continued to expand in many European countriesin 2002. Two features that have been noticed are worth mentioning. Firstly, countries that see anepidemic rise in MRSA frequently witness a fast increase and spread in many hospitals, but MRSAproportions appear to reach saturation levels after a couple of years. Secondly, European countrieswith longstanding high MRSA rates maintained resistance proportions between 40% and 50%(Portugal, Italy and Greece). It is not understood what limits this dissemination and determines thenational carrying capacity. Despite the relative uniformity of resistance proportions amonghyperendemic countries, some hospitals warrant attention since they see much higher MRSA ratesthan the national average. To better understand the factors that drive the success of certain highlyprevalent clones, attention should be turned to hospitals with longstanding and extreme MRSAfigures. They represent ideal study sites for specific national and international investigations thatwould potentially identify a set of common conductive ecological conditions.

Vancomycin-resistant enterococci (VRE) mainly belong to the species E. faecium and occur inepidemic proportions in a few countries. Nevertheless, six countries reported proportions greater orequal to 10% in 2002 compared to only 4 countries in 2001. It has been shown that invasive VREbelong to hospital-associated strains, many of them phylogenetically related and carrying the espgene [2]. This means that appropriate methods of strain identification can potentially identify theseparticularly important strains early enough to prevent hospital outbreaks, and EARSS will be able totrace their regional and international dissemination with the use of spatial analysis.

In E. coli, aminopenicillin resistance continued to expand and the median resistance proportionincreased from 44.5% in 2001 to 48% in 2002. The same trend was recognised for third-generationcephalosporins. The latter increase was mainly due to the spread of ESBL-producing strains in someeastern European countries. The most rapid rise of resistance frequencies in 2002 was observed forfluoroquinolone-resistant E. coli. Resistance increased in 16 of 21 countries; 8 of them observedproportions that were at least 1.5 times greater in 2002 than in the previous year. It has been arguedthat fluoroquinolone resistance mainly occurs in phylogenetically diverse subgroups other than veryvirulent strains and may be derived from animal sources [3]. The exchange of strain-specificinformation would enhance the ability of EARSS to characterise the nature of this threateningdevelopment, which would be helpful in efforts to improve resistance surveillance.

CHAPTER 6. Conclusions and future initiatives 47

EARSS has become an internationally accepted surveillance organisation in the last 4 years. EARSSprovides meaningful information on the status and trends of AMR in the European region. However,some obstacles have not entirely been overcome and remain to be addressed in the future to improveon the accuracy and validity of the data. Susceptibility tests were originally devised and are routinelyused as guidance for therapeutic decision making in clinical services. The use of these routinelaboratory results for public health purposes has not been without controversy. The main concern isthat EARSS results are based on clinical breakpoints interpreted in S, I, and R categories. Thesediffer among laboratories depending on the various national guidelines used. Nonetheless, routineEQA exercises performed annually throughout the EARSS network were able to demonstrate thatover 95% of the laboratories come to concordant results when the guidelines agreed on breakpointsthat clearly separate wild type from resistant bacteria. This means that most of the laboratoriessatisfactorily identify micro-organisms that have acquired the ability to circumvent the effect of theantibiotic to which they would normally be expected to be susceptible. The initiative taken byEUCAST to harmonise the existing clinical breakpoints and define epidemiological cut off valuesfor surveillance [4] will certainly improve the completeness of conclusions drawn by EARSS.

The EARSS network with its 700 participating laboratories provides the ideal basis for furtherepidemiological and ecological research towards a better understanding of the emergence and spreadof resistance in the European region. One property of the EARSS initiative has, in this respect, notbeen exploited to its full potential: the capacity to process data based on strain-specific identificationof pathogens. Once this becomes possible, EARSS will not only provide a novel approach topertinent research questions, but value will be added to its role as a repository of knowledge forinformed policy decision. We envision EARSS becoming the platform for a warning system for thedetection and identification of pathogens and clones with particular public health importance interms of AMR and virulence properties. This becomes especially clear when one considers thepotentials of internet-based information exchange among the participating laboratories, which, afterall, are the centres of local expertise.

Appendix A. Country Summary Sheets

In the following appendix, country-specific resistance information is presented together withdenominator data and the characteristics of the participating laboratories and hospitals.

Explanation to the country summary sheets:

Denominators: Table 1 and 2 and Figures 1 and 2 give an indication of the sample size and therepresentativeness of the country-specific resistance data available to EARSS.

Table 1 displays results of the laboratories and hospitals that provided denominator data (i.e. thatresponded to the questionnaire) and thus only includes the laboratories that reported AST results toEARSS in 2002, and provided blood culture information and the hospitals that reported AST resultsto EARSS in 2002, and provided their number of hospital beds. For details about the calculation ofthe average annual occupancy rate, the estimated catchment population and the percentage of thetotal population covered, we refer to the technical notes (Appendix B). If data were not availablethis is stated as “na”.

Figure 1 gives and indication about the degree of specialisation of the participating hospitals, andFigure 2 shows the geographic location of the laboratories reporting in 2002. The size of the dots inthe maps represents the number of laboratories in that location/town.

Antibiotic resistance 1999-2002: Table 3 provides information on the proportion of invasivebacterial isolates not susceptible to the antibiotics or antibiotic classes mentioned in the EARSSprotocols. From the majority of all non-susceptible S. pneumoniae and S. aureus isolates wereceived the corresponding MIC or Etest result, according to the EARSS protocols, however forsome of the non susceptible isolates this information is missing. The table also includeserythromycin susceptibility for S. pneumoniae. Any interpretation of Table 3 should also take intoaccount the small sample size for E. faecium reported to EARSS.

Table 4 gives details about the origin of the isolate (patient, source and hospital department). Theabbreviations used in this table stand for; PNSP = pencillin non-susceptible S. pneumoniae, MRSA= methicillin-resistant S. aureus, FREQ = fluoroquinolone-resistant E. coli, and VRE = vancomycinresistant (I+R) E. faecalis or E. faecium. If the number of isolates in a certain category accounts forless than 0.5% of the total number of isolates, the % total is set at 0 and the % resistance is notshown.

Local variation: Figures 3 and 4 show national distribution in the proportions of PNSP and MRSAby laboratory and by hospital, respectively.

APPENDIX A 49

For both Figures, a minimum of 5 isolates and at least 2 years of participation in EARSS for eachlaboratory or hospital was required, before being included into the presentation. If an ‘X’ isdisplayed at the end of a hospital code this means that the hospital code is not provided;consequently, this can apply for one or more unknown hospitals.

Appendix B. Technical Notes

Notes to Chapter 3 and Country Summary Sheets (Appendix A)

Inclusion criteriaTo be included in the analyses presented in Chapter 3, countries, laboratories and hospitals had toprovide both denominator data and AST results in 2002. Also, a laboratory had to indicate bloodculture frequencies and the number of hospital beds for each hospital served.Denmark and Ireland reported aggregated data and were therefore not included inlaboratory/hospital-specific analysis in Chapter 3. However, the data provided by these countries areincluded in Appendix A (country summary sheets).

Presentation of variables per countryCatchment population, number of beds, patient-days and number of blood culture sets wereaggregated by country.

FormulasFrom each hospital, either hospital occupancy rate or the number of patient-days was required.Occupancy rates could then be derived from patient-days, and vice versa.Hospital occupancy rate was calculated if not provided or if the occupancy was consideredimplausible (e.g. less than 25% or more than 125%). The following formula was used:

no. of patient-days / (no. of beds × 365). The average occupancy rate per country was calculated as follows:

[Σ(occupancy rate × no. of beds)/ Σ(no. of beds)]

If the number of patient-days per hospital was not provided or if considered implausible (e.g. whenyielding a calculated occupancy rate of less than 25% or more than 125%), the value was estimatedaccording to the following formula:

no. of beds × annual occupancy rate × 365.

For calculation of the total catchment population, hospitals providing single speciality(superregional) type of care (classified as other, e.g. oncology or psychiatric hospitals) were notincluded because we considered this population as probably overlapping with the catchmentpopulations of the hospitals providing general care.

Population coverage per country was calculated using the following formula:Σ(hospital catchment population)/total population

The total population of mid 2002 was obtained from the CIA World Fact book.

Detection limits for MRSA and VRE incidences (Table 3.3) were calculated in case of reported nul-incidence so that p < p upper limit of confidence interval as follows:

p < (1-p)n

at p=0.05, the detection limit is then given by (1-p)n = 0.05

APPENDIX B 109

in which n is the number of isolates tested. After calculation of p, the detection limit for the incidencerate can be calculated as follows:

detection limit = n/patient-days × 100 000 × p

Notes to Chapter 5

Inclusion criteria mapsTo be coloured in the maps a country had to report at least 10 isolates of a specific pathogen in 2002.

Trend analysisTrend analysis over the years was calculated using the Cochran-Armitage test (p ≤ 0.05).

Aggregated dataFor S. pneumoniae France provided aggregated AST data of the first two quarters of 2002 from theirnational pneumococci surveillance system
