European survey on the current surveillance practices, management guidelines, treatment pathways and heterogeneity of testing of Clostridioides difficile, 2018-2019: results from The Combatting Bacterial Resistance in Europe CDI (COMBACTE-CDI).

BACKGROUND: Awareness and compliance with international guidelines for diagnosis and clinical management of Clostridioides difficile infection (CDI) are unknown. AIM: To compare the awareness and compliance with the recommended strategies for diagnosis and clinical management of CDI across Europe in 2018-2019. METHODS: Hospital sites and their associated community practices across 12 European countries completed an online survey in 2018-2019, to report on their practices in terms of surveillance, prevention, diagnosis, and treatment of CDI. Responses were collected from 105 hospitals and 39 community general practitioners (GPs). FINDINGS: Hospital sites of 11 countries reported participation in national surveillance schemes compared with six countries for international schemes. The European Society of Clinical Microbiology and Infectious Diseases (ESCMID)-recommended CDI testing methodologies were used by 82% (86/105) of hospitals, however countries reporting the highest incidence of CDI used non-recommended tests. Over 75% (80/105) of hospitals were aware of the most recent European CDI treatment guidelines at the time of this survey compared with only 26% (10/39) of surveyed GPs. However, up to 15% (16/105) of hospitals reported using the non-recommended metronidazole for recurrent CDI cases, sites in countries with lower awareness of CDI treatment guidelines. Only 37% (39/105) of hospitals adopted contact isolation precautions in case of suspected CDI. CONCLUSION: Good awareness of guidelines for the management of CDI was observed across the surveyed European hospital sites. However, low compliance with diagnostic testing guidelines, infection control measures for suspected CDI, and insufficient awareness of treatment guidelines continued to be reported in some countries.

Detection and prevalence of carbapenem-resistant Gram-negative bacteria among European laboratories in the COMBACTE network: a COMBACTE LAB-Net survey.

Antimicrobial resistance (AMR) represents a global public health threat that jeopardises the progress medicine has made over the last century. To confront AMR, the Innovative Medicines Initiative (IMI) has supported the development of a large network of hospitals and laboratories in Europe as part of the New Drugs for Bad Bugs (ND4BB) programme and the COMBACTE projects. COMBACTE LAB-Net conducted a pilot survey on distribution and usage of carbapenem resistance detection methods among laboratories in the COMBACTE network in two clinical trials as part of the COMBACTE-CARE project. The survey was sent out to 211 laboratories in 20 European countries between May 2015 and June 2017. Answers were collected from 165 laboratories (78%). Sixty laboratories (36%) reported an outbreak of carbapenem-resistant (CR) Enterobacteriaceae during one of the two years preceding the completion of the survey. High rates of CR Acinetobacter spp. above 50% were reported by 74 laboratories (47%), particularly in the Western Balkan countries where the rates were sometimes higher than 90%. Apart from determining the antimicrobial susceptibility of isolates, laboratories also used various methods, such as Matrix Assisted Laser Desorption Ionization - Time of Flight (MALDI-TOF), Carbapenemase Nordmann-Poirel (Carba NP) test or molecular methods, to detect CR Gram-negative bacteria. The survey resulted in the selection of sites with high resistance rates that successfully recruited many patients in the EURECA observational clinical trial.
