Substance use and related harms in the context of COVID-19: a conceptual model. / Consommation de substances et méfaits connexes dans le contexte de la COVID-19 : un modèle conceptuel.

As the effects of COVID-19 have been unfolding, growing attention has been paid to the intersection of COVID-19 and substance use and the related harms. However, there are few theories and little empirical evidence to guide investigations in this area. To advance this emerging area of inquiry, we present a conceptual model that synthesizes evidence, information and knowledge on substance use and related harms in the context of the pandemic. The conceptual model offers a visual representation of the connections between the pandemic and substance use and related harms, and can be used to identify areas for future research.

As of June 2020, substance use and related harms in the context of a pandemic remained largely uninvestigated. The COVID-19 pandemic may impact how Canadians use substances and may present specific challenges and harms among people who use substances. The conceptual model in this paper offers a synthesis of evidence, information and knowledge of the concepts and associations relevant to substance use and harms in the context of the pandemic. Relevant concepts were synthesized into five interrelated domains that can be used to identify areas for future research into substance use and related harms in the context of COVID-19: substance use as a means of coping; changes in social support and networks; availability and accessibility of services; increased risk of COVID-19 transmission among people who use substances; and increased risk of severe outcomes.

En juin 2020, la consommation de substances et les méfaits connexes dans le contexte de la pandémie restaient largement inexplorés. La pandémie de COVID-19 peut avoir une incidence sur la façon dont les Canadiens consomment des substances, ce qui pourrait entraîner des défis et des méfaits particuliers chez ces personnes. Le modèle conceptuel présenté dans le présent document offre une synthèse des données probantes, de l'information et des connaissances sur les concepts et les associations relatifs à la consommation de substances et aux méfaits dans le contexte de la pandémie. Les concepts pertinents ont été synthétisés en cinq domaines interreliés qui peuvent être utilisés pour déterminer les futurs domaines de recherche sur la consommation de substances et les méfaits connexes dans le contexte de la COVID-19, soit la consommation de substances comme stratégie d'adaptation, les changements relatifs au soutien social et aux réseaux; la disponibilité et l'accessibilité des services; le risque accru de transmission de la COVID-19 chez les personnes qui consomment des substances; et le risque accru de conséquences graves.

The cognitive processes underpinning clinical decision in triage assessment: a theoretical conundrum?

High quality clinical decision-making (CDM) has been highlighted as a priority across the nursing profession. Triage nurses, in the Accident and Emergency (A&E) department, work in considerable levels of uncertainty and require essential skills including: critical thinking, evaluation and decision-making. The content of this paper aims to promote awareness of how triage nurses make judgements and decisions in emergency situations. By exploring relevant literature on clinical judgement and decision-making theory, this paper demonstrates the importance of high quality decision-making skills underpinning the triage nurse's role. Having an awareness of how judgements and decisions are made is argued as essential, in a time where traditional nurse boundaries and responsibilities are never more challenged. It is hoped that the paper not only raises this awareness in general but also, in particular, engages the triage nurse to look more critically at how they make their own decisions in their everyday practice.
