A step forward in antibiotic use and resistance monitoring: a quarterly surveillance system pilot in 11 European Union/European Economic Area countries, September 2017 to May 2020.

BackgroundSurveillance of antimicrobial resistance (AMR) and antimicrobial use (AMU) in Europe is currently annual.AimTo study the feasibility and scalability of a quarterly AMR/AMU surveillance system in the European Union/European Economic Area (EU/EEA).MethodsWe conducted a longitudinal study within the scope of the EU-JAMRAI project. Seventeen partners from 11 EU/EEA countries prospectively collected 41 AMU and AMR indicators quarterly from September 2017 to May 2020 for the hospital sector (HS) and primary care (PC). Descriptive statistics and coefficients of variation (CV) analysis were performed.ResultsData from 8 million hospital stays and 45 million inhabitants per quarter were collected at national (n = 4), regional (n = 6) and local (n = 7) levels. Of all partners, five were able to provide data within 3 months after each preceding quarter, and eight within 3-6 months. A high variability in AMU was found between partners. Colistin was the antibiotic that showed the highest CV in HS (1.40; p < 0.0001). Extended-spectrum beta-lactamase-producing Escherichia coli presented the highest incidence in HS (0.568 ± 0.045 cases/1,000 bed-days per quarter), whereas ciprofloxacin-resistant E. coli showed the highest incidence in PC (0.448 ± 0.027 cases/1,000 inhabitants per quarter). Barriers and needs for implementation were identified.ConclusionThis pilot study could be a first step towards the development of a quarterly surveillance system for AMU and AMR in both HS and PC in the EU/EEA. However, committed institutional support, dedicated human resources, coordination of data sources, homogeneous indicators and modern integrated IT systems are needed first to implement a sustainable quarterly surveillance system.

SARS-CoV-2 in health and care staff in Norway, 2020. / SARS-CoV-2 blant ansatte i helse- og omsorgstjenesten.

BACKGROUND: The COVID-19 pandemic is placing considerable pressure on health services around the world. In Norway, the incidence rate among the working-age population (20-69 years) for the whole of 2020 was 1.11 %. In this study, we describe diagnosed infection among staff in the health service, based on register data. MATERIAL AND METHOD: From the emergency preparedness register, Beredt C19, we identified 382 332 persons employed in selected occupational groups in the health service in week 9 of 2020, and investigated incidence and testing activity for diagnosed SARS-CoV-2 according to occupation, age, sex, country of birth, place of residence and place of work, for the whole of 2020. RESULTS: The incidence in the health service for the entire period was 1.48 % (5673/382 332). Diagnosed infection was highest among ambulance personnel and nursing home staff, with an incidence of 1.83 % (95/5203) and 1.86 % (1534/82 776), respectively. Doctors were tested most frequently (1.45 tests per person), and the proportion of positive tests was highest among cleaners (2.78 %) and ambulance personnel (1.57 %). Imported infection was highest for dentists (14.3 %), psychologists (12.8 %) and doctors (10.8 %). INTERPRETATION: There are variations in the incidence of diagnosed infections among employees in the health service. Some of this can likely be viewed in connection with high testing activity, imported infection, age and sex distribution, place of residence and country of birth, and outbreaks in different health services. More research and data are needed to ascertain whether occupational practice is associated with increased risk of SARS-CoV-2 infection.
