Abstract: The SARS-CoV-2 pandemic has highlighted the importance of viable infection surveillance and the relevant infrastructure. From a German perspective, an integral part of this infrastructure, genomic pathogen sequencing, was at best fragmentary and stretched to its limits due to the lack or inefficient use of equipment, human resources, data management and coordination. The experience in other countries has shown that the rate of sequenced positive samples and linkage of genomic and epidemiological data (person, place, time) represent important factors for a successful application of genomic pathogen surveillance. Planning, establishing and consistently supporting adequate structures for genomic pathogen surveillance will be crucial to identify and combat future pandemics as well as other challenges in infectious diseases such as multi-drug resistant bacteria and healthcare-associated infections. Therefore, the authors propose a multifaceted and coordinated process for the definition of procedural, legal and technical standards for comprehensive genomic pathogen surveillance in Germany, covering the areas of genomic sequencing, data collection and data linkage, as well as target pathogens. A comparative analysis of the structures established in Germany and in other countries is applied. This proposal aims to better tackle epi- and pandemics to come and take action from the "lessons learned" from the SARS-CoV-2 pandemic

Abstract: Background Antibiotic resistance, either intrinsic or acquired, is a major obstacle for treating bacterial infections. Aim Our objective was to compare the country-specific species distribution of the four Gram-negative species Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Acinetobacter species and the proportions of selected acquired resistance traits within these species. Method We used data reported for 2016 to the European Antimicrobial Resistance Surveillance Network (EARS-Net) by 30 countries in the European Union and European Economic Area. Results The country-specific species distribution varied considerably. While E. coli accounted for 31.9% to 81.0% (median: 69.0%) of all reported isolates, the two most common intrinsically resistant species P. aeruginosa and Acinetobacter spp. combined (PSEACI) accounted for 5.5% to 39.2% of isolates (median: 10.1%). Similarly, large national differences were noted for the percentages of acquired non-susceptibility to third-generation cephalosporins, carbapenems and fluoroquinolones. There was a strong positive rank correlation between the country-specific percentages of PSEACI and the percentages of non-susceptibility to the above antibiotics in all four species (rho > 0.75 for 10 of the 11 pairs of variables tested). Conclusion Countries with the highest proportion of P. aeruginosa and Acinetobacter spp. were also those where the rates of acquired non-susceptibility in all four studied species were highest. The differences are probably related to national differences in antibiotic consumption and infection prevention and control routines

Abstract: Objectives To evaluate whether a multimodal intervention in general practice reduces the proportion of second line antibiotic prescriptions and the overall proportion of antibiotic prescriptions for uncomplicated urinary tract infections in women. Design Parallel, cluster randomised, controlled trial. Setting General practices in five regions in Germany. Data were collected between 1 April 2021 and 31 March 2022. Participants General practitioners from 128 randomly assigned practices. Interventions Multimodal intervention consisting of guideline recommendations for general practitioners and patients, provision of regional data for antibiotic resistance, and quarterly feedback, which included individual first line and second line proportions of antibiotic prescribing, benchmarking with regional or supra-regional practices, and telephone counselling. Participants in the control group received no information on the intervention. Main outcome measures Primary outcome was the proportion of second line antibiotics prescribed by general practices, in relation to all antibiotics prescribed, for uncomplicated urinary tract infections after one year between the intervention and control group. General practices were randomly assigned in blocks (1:1), with a block size of four, into the intervention or control group using SAS version 9.4; randomisation was stratified by region. The secondary outcome was the prescription proportion of all antibiotics, relative within all cases (instances of UTI diagnosis), for the treatment of urinary tract infections after one year between the groups. Adverse events were assessed as exploratory outcomes. Results 110 practices with full datasets identified 10 323 cases during five quarters (ie, 15 months). The mean proportion of second line antibiotics prescribed was 0.19 (standard deviation 0.20) in the intervention group and 0.35 (0.25) in the control group after 12 months. After adjustment for preintervention proportions, the mean difference was −0.13 (95% confidence interval −0.21 to −0.06, P0.001). The overall proportion of all antibiotic prescriptions for urinary tract infections over 12 months was 0.74 (standard deviation 0.22) in the intervention and 0.80 (0.15) in the control group with a mean difference of −0.08 (95% confidence interval −0.15 to −0.02, P0.029). No differences were noted in the number of complications (ie, pyelonephritis, admission to hospital, or fever) between the groups.

Abstract: Die SARS-CoV-2-Pandemie hat ein Defizit an essentieller infektionsepidemiologischer Infrastruktur, insbesondere in Bezug auf die Genomische Erreger-Surveillance (GES) in Deutschland, gezeigt. Zur Vorbereitung auf zukünftige pandemische Notlagen sehen es die Autor*innen als dringend erforderlich an, dieses bestehende Defizit durch den Aufbau einer leistungsfähigen Infrastruktur für GES zu beheben. Ein derartiges Netzwerk kann auf bereits regional initiierten Strukturen, Prozessen und Interaktionen aufbauen und diese weiter optimieren. Es kann zukünftig mit einer hohen Anpassungsfähigkeit auf aktuelle und kommende Herausforderungen reagieren. Ziele der vorliegenden Arbeit sind die Verdeutlichung der Dringlichkeit und Skizzierung von Vorschlägen zur Etablierung eines effizienten, anpassungsfähigen und reaktionsbereiten GES-Netzwerkes unter Berücksichtigung von externen Rahmenbedingungen und internen Standards. Die erarbeiteten Vorschläge basieren auf der Grundlage globaler und länderspezifischer Best Practices und Strategiepapiere. Zu den konkreten nächsten Schritten zur Realisierung einer integrierten GES zählen die Ermöglichung der Verknüpfung epidemiologischer Daten mit Genomdaten der Erreger, die gemeinsame und koordinierte Nutzung von vorhandenen Ressourcen, die Nutzbarmachung der so gewonnenen Surveillance-Daten für relevante Entscheidungstragende, den Öffentlichen Gesundheitsdienst und die wissenschaftliche Gemeinschaft sowie die Einbindung aller Stakeholder. Der Aufbau eines GES-Netzwerkes ist essentiell für die kontinuierliche, stabile, aktive Überwachung des Infektionsgeschehens in Deutschland sowohl während pandemischer Phasen als auch außerhalb dieser
