[Breathing filters in hospital, COVID first-wave experience]. / Filtres respiratoires à l'hôpital, l'expérience de la première vague de COVID.

During the coronavirus pandemic, breathing filters have been essential in the medical care of infected patients. The worldwide demand caused a disruption in the supply, which led to a multiplication of the references used. The lack of formation available on the subject was an impediment for pharmacists (buyer, medical devices, intensive car unit) and it appears to be necessary to redact a formation about those filters, from the experience acquired during the sanitary crisis. Multiple breathing filters references exist which may be classify according to their filtration mechanism (mechanical filtration or electrostatic filtration) and by the eventual presence of a humidifying action (Heat and Moisture Exchangers; hydrophobic, hygroscopic, or mixed). In anaesthesia, the use of pure mechanical filter is preferred; in resuscitation unit, heat and moisture exchangers filter or simple filter plus heated humidifier are used. During the COVID-19 pandemic, the filters duration of use has been lengthened to limit the disruption risk.

[Point-of-care testing: place of France in the world National survey in healthcare establisments in 2019]. / Examens de biologie médicale délocalisée : place de la France dans le monde Enquête nationale en 2019 dans les établissements de santé.

The point-of-care tests (POCT) are subject to accreditation. A national inventory survey provides a synthesis of knowledge. The survey distributed 31 questions in 2019. 147 responses were received (75% biologists, 49% CHU, 42% CHG). Only 20.41% are accredited ISO22870, the majority for <50% of the medical departments; 70% say they are going there at the end of 2019 or in 2020. The maps are unknown for 32% (EBMD) and 82% (TROD). Visibility is poor with: medical establishment committee (40%), IT department (31%). Connection is necessary for 87-95% depending on the criterion (QC, authorizations, etc.) and 66% of answers highlight that less than 50% of connexion is effective. The major advantage is the delay of the result (62.5%), then the relationship with the health teams (33.3%). The disadvantages: difficulty of the quality approach (45%), cost of tests (34.3%). Human resource requirements are identified for technicians (82%) and biologists (76%). The multiplicity of sites, devices and operators means that it is difficult to set up and maintain. Biology outside the laboratories, under biological responsibility, must meet a rigorous imperative quality approach.
