    Le pneumocoque (Streptococcus pneumoniae) entraîne un grand nombre d’infections de diverses natures, d’hospitalisations, de prescriptions d’antibiotiques et de décès au niveau mondial ainsi qu’au Canada. Deux types de vaccins ont été développés pour réduire le fardeau des infections à pneumocoque, en visant plus particulièrement les infections invasives à pneumocoque (IIP) et les sérotypes qui sont le plus souvent en cause. Les vaccins pneumococciques conjugués 7-valent (contient 7 sérotypes; VPC-7), 10-valent (VPC-10) et 13-valent (VPC-13) sont principalement destinés aux enfants. Le vaccin pneumococcique polysaccharidique 23-valent (VPP-23) est principalement utilisé chez les personnes de 65 ans et plus.

    Question

    In the context of the community transmission of SARS-CoV-2 and the presence of residents of seniors’ residential and long-term care centres (CHSLDs) in hemodialysis clinics, what are the recommendations to apply when managing dialysis users in ambulatory hemodialysis units?

    Context

    • This information is provided to clarify the recommendations for preventing and controlling COVID-19 infections specifically in ambulatory hemodialysis centres.
    • Although the initial question concerns clients from CHSLDs, the recommendations herein apply to all clients who receive care in hemodialysis units, regardless of their origin.
    • This information complements, but does not replace, the general recommendations regarding COVID-19. This advice is...

    Scope of Recommendations

    These recommendations apply to aerosol-generating medical procedures (AGMPs) carried out on patients who are suspected or confirmed cases of COVID-19. In contexts of sustained community transmission, risk assessments must be carried out to determine whether these recommendations shall also apply during AGMPs on individuals who are asymptomatic or have unknown COVID-19 status. Also, a negative result from PCR testing done in the 24-48 hours prior to an AGMP on a patient who does not present COVID-19 symptoms and has had no significant contact with the virus, may result in the AGMP being carried out according to standard precautions, unless the presence of another contagious infectious disease (e.g., tuberculosis) is suspected or suspected COVID-19...

    Foreword

    This publication uses the term "disinfection" of N95 masks to refer to the chemical or physical process that inactivates infectious agents. It should be noted that the various reference publications and documents on the subject consulted by the Centre d’expertise en retraitement des dispositifs médicaux (CERDM) use the terms "decontamination," "disinfection," or both. The CERDM has chosen the term "disinfection" to conform to the reprocessing nomenclature that is generally accepted in Canada (CSA Z314.18).

    Objective

    This document is intended for managers and clinical personnel involved in medical device reprocessing (MDR).

    Its purpose is to describe the guidelines to be followed for the overall process of collecting, disinfecting and storing...

    This evaluation presents promising processes and devices authorized by Health Canada for the disinfection of single-use N95 masks, as alternatives of last resort in the context of the COVID-19 pandemic and the real shortage of N95 masks. The results for disinfection of N95 masks reported in the literature derive from pilot scale tests. The results of N95 disinfection process testing allow for verification of the safety and feasibility criteria used in this evaluation. Feasibility criteria may vary depending on the disinfection process and device used. It is therefore important to refer to the disinfection instructions for N95 masks provided by the manufacturer of the device used.

    An easily accessible short-term option is the disinfection of N95 masks in the low-temperature...

    Note that the information herein is based on the scientific evidence available on the date of this statement. Several questions on operating room setup for suspected and confirmed cases of COVID-19 have come from these facilities. Below are the measures to implement.

    Preparatory Measures

    • Postpone all elective surgeries (for at least one month) and if possible, postpone urgent surgeries until the case is no longer contagious or until a test rules out the possibility of COVID-19 for a patient with compatible symptoms.
    • Prepare for all urgent surgery scenarios for suspected or confirmed cases of COVID-19 with the various teams: technical services, IPC, operating room, surgeons, anesthesiologists...

The CERDM has chosen the term “disinfection” to conform to the reprocessing nomenclature that is generally accepted in Canada (CSA Z314.18). According to this nomenclature, the term decontamination is more general and includes the process of cleaning followed by the inactivation of infectious agents. However, in the context of reprocessing of N95 masks, only one step, aimed at inhibiting various...

    COVID-19 preventive measures in the workplace
    These measures apply when sustained community transmission has been confirmed by public health authorities.
    N95 masks generally have a shelf life of five years following the date of manufacture.

    According to the Centers for Disease Control and Prevention (CDC), if there is a shortage of unexpired masks, expired N95 masks may be used in the context of the COVID‑19 pandemic in certain conditions (https://www.cdc.gov/coronavirus/2019-ncov/release-stockpiled-N95.html February 28, 2020) :

    Contexte

    Ce rapport de l’Enquête québécoise sur la vaccination contre la grippe saisonnière, le pneumocoque, le zona et sur les déterminants de la vaccination présente les résultats d’une enquête populationnelle réalisée en 2018 au Québec. Des données ont été recueillies sur les couvertures vaccinales contre la grippe, contre le pneumocoque et contre le zona et sur les attitudes et les perceptions sur la vaccination. Rappelons que les groupes ciblés par le programme de vaccination 2017-2018 contre la grippe étaient les personnes âgées de 60 ans ou plus, les enfants en bonne santé âgés de 6 à 23 mois, les personnes âgées de 2 ans ou plus atteintes d’une ou plusieurs maladies chroniques, les personnes qui, dans le cadre de leur travail ou de leurs activités...

    La recherche de N. gonorrhoeae aux sites urogénitaux s’effectue le plus souvent par un test d’amplification des acides nucléiques (TAAN). Dans certaines situations, une culture est aussi recommandée. Bien qu’aucune trousse de TAAN ne soit actuellement homologuée par Santé Canada pour l’analyse des échantillons extragénitaux, les laboratoires du réseau peuvent accepter ces échantillons, en émettant un commentaire « sous réserve ».

    Des espèces saprophytes de Neisseria sp (autres que N. gonorrhoeae) peuvent être présentes dans les échantillons, particulièrement ceux prélevés au pharynx. Ces espèces possèdent des acides nucléiques homologues à N. gonorrhoeae, ou ont subi des échanges génétiques avec N. gonorrhoeae; elles peuvent donc...
