"We're sinking": a qualitative interview-based study on stakeholder perceptions of structural and process limitations to the Canadian healthcare system.

BACKGROUND: Despite longstanding efforts and calls for reform, Canada's incremental approach to healthcare changes has left the country lagging behind other OECD nations. Reform to the Canadian healthcare system is essential to develop a higher performing system. This study sought to gain a deeper understanding of the views of Canadian stakeholders on structural and process deficiencies and strategies to improve the Canadian healthcare system substantially and meaningfully. METHODS: We conducted individual, ~ 45-minute, semi-structured virtual interviews from May 2022 to August 2022. Using existing contacts and snowball sampling, we targeted one man and one woman from five regions in Canada across four stakeholder groups: (1) public citizens; (2) healthcare leaders; (3) academics; and (4) political decision makers. Interviews centered on participants' perceptions of the state of the current healthcare system, including areas where major improvements are required, and strategies to achieve suggested enhancements; Donabedian's Model (i.e., structure, process, outcomes) was the guiding conceptual framework. Interviews were audio-recorded, transcribed verbatim, and de-identified, and inductive thematic analysis was performed independently and in duplicate according to published methods. RESULTS: The data from 31 interviews with 13 (41.9%) public citizens, 10 (32.3%) healthcare leaders, 4 (12.9%) academics, and 4 (12.9%) political decision makers resulted in three themes related to the structure of the healthcare system (1. system reactivity; 2. linkage with the Canadian identity; and 3. political and funding structures), three themes related to healthcare processes (1. staffing shortages; 2. inefficient care; and 3. inconsistent care), and three strategies to improve short- and long-term population health outcomes (1. delineating roles and revising incentives; 2. enhanced health literacy; 3. interdisciplinary and patient-centred care). CONCLUSION: Canadians in our sample identified important structural and process limitations to the Canadian healthcare system. Meaningful reforms are needed and will require addressing the link between the Canadian identity and our healthcare system to facilitate effective development and implementation of strategies to improve population health outcomes.

A natural language model to automate scoring of autobiographical memories.

Biases in the retrieval of personal, autobiographical memories are a core feature of multiple mental health disorders, and are associated with poor clinical prognosis. However, current assessments of memory bias are either reliant on human scoring, restricting their administration in clinical settings, or when computerized, are only able to identify one memory type. Here, we developed a natural language model able to classify text-based memories as one of five different autobiographical memory types (specific, categoric, extended, semantic associate, omission), allowing easy assessment of a wider range of memory biases, including reduced memory specificity and impaired memory flexibility. Our model was trained on 17,632 text-based, human-scored memories obtained from individuals with and without experience of memory bias and mental health challenges, which was then tested on a dataset of 5880 memories. We used 20-fold cross-validation setup, and the model was fine-tuned over BERT. Relative to benchmarking and an existing support vector model, our model achieved high accuracy (95.7%) and precision (91.0%). We provide an open-source version of the model which is able to be used without further coding, by those with no coding experience, to facilitate the assessment of autobiographical memory bias in clinical settings, and aid implementation of memory-based interventions within treatment services.

Thoracic ultrasound may improve paramedic diagnostic and management accuracy in undifferentiated respiratory distress.

Objectives: Patients with chronic obstructive pulmonary disease (COPD) and congestive heart failure (CHF) exacerbations present with similar history and physical examination findings. This complicates both the diagnostic process and the creation of appropriate treatment plans for patients presenting in respiratory distress, particularly in the prehospital setting. Thoracic point-of-care-ultrasound (POCUS) may increase diagnostic accuracy; however, its potential to improve patient management by emergency medical services clinicians is unknown. We aimed to determine whether a brief thoracic POCUS educational intervention would improve prehospital diagnostic accuracy and treatment plans for patients with COPD and CHF exacerbations. Methods: In this prospective pre-/post-study, paramedics completed a thoracic POCUS training program. The pre-test presented history and physical examination data for 10 patients and asked paramedics to diagnose each patient with COPD or CHF exacerbation and to select the appropriate treatment(s). The post-test asked paramedics to interpret ultrasound images in addition to selecting diagnosis and treatment(s). Pre-post differences in average cumulative diagnostic and management accuracy were analyzed using paired two-tailed t-tests. Results: Thirty-three paramedics participated in the study. At baseline, paramedics selected the accurate patient diagnosis and treatment(s) 73% and 60% of the time, respectively. On the post-test, diagnostic accuracy improved by 17% (95% confidence interval [CI]: 11-24, p < 0.001) and appropriate treatment selection improved by 23% (95% CI: 16-28, p < 0.001). Paramedics correctly interpreted ultrasound images 90% of the time. Conclusion: Effective training of paramedics to recognize the clinical scenario of undifferentiated respiratory distress and their associated thoracic ultrasound images may lead to improved treatment plans.

The evolution of vaccine hesitancy through the COVID-19 pandemic: A semi-structured interview study on booster and bivalent doses.

We sought in-depth understanding on the evolution of factors influencing COVID-19 booster dose and bivalent vaccine hesitancy in a longitudinal semi-structured interview-based qualitative study. Serial interviews were conducted between July 25th and September 1st, 2022 (Phase I: univalent booster dose availability), and between November 21st, 2022 and January 11th, 2023 (Phase II: bivalent vaccine availability). Adults (≥18 years) in Canada who had received an initial primary series and had not received a COVID-19 booster dose were eligible for Phase I, and subsequently invited to participate in Phase II. Twenty-two of twenty-three (96%) participants completed interviews for both phases (45 interviews). Nearly half of participants identified as a woman (n = 11), the median age was 37 years (interquartile range: 32-48), and most participants were employed full-time (n = 12); no participant reported needing to vaccinate (with a primary series) for their workplace. No participant reported having received a COVID-19 booster dose at the time of their interview in Phase II. Three themes relating to the development of hesitancy toward continued vaccination against COVID-19 were identified: 1) effectiveness (frequency concerns; infection despite vaccination); 2) necessity (less threatening, low urgency, alternate protective measures); and 3) information (need for data, contradiction and confusion, lack of trust, decreased motivation). The data from interviews with individuals who had not received a COVID-19 booster dose or bivalent vaccine despite having received a primary series of COVID-19 vaccines highlights actionable targets to address vaccine hesitancy and improve public health literacy.

Factors affecting hesitancy toward COVID-19 vaccine booster doses in Canada: a cross-national survey.

OBJECTIVE: COVID-19 transmission, emergence of variants of concern, and weakened immunity have led to recommended vaccine booster doses for COVID-19. Vaccine hesitancy challenges broad immunization coverage. We deployed a cross-national survey to investigate knowledge, beliefs, and behaviours toward continued COVID-19 vaccination. METHODS: We administered a national, cross-sectional online survey among adults in Canada between March 16 and March 26, 2022. We utilized descriptive statistics to summarize our sample, and tested for demographic differences, perceptions of vaccine effectiveness, recommended doses, and trust in decisions, using the Rao-Scott correction for weighted chi-squared tests. Multivariable logistic regression was adjusted for relevant covariates to identify sociodemographic factors and beliefs associated with vaccine hesitancy. RESULTS: We collected 2202 completed questionnaires. Lower education status (high school: odds ratio (OR) 1.90, 95% confidence interval (CI) 1.29, 2.81) and having children (OR 1.89, CI 1.39, 2.57) were associated with increased odds of experiencing hesitancy toward a booster dose, while higher income ($100,000-$149,999: OR 0.60, CI 0.39, 0.91; $150,000 or more: OR 0.49, CI 0.29, 0.82) was associated with decreased odds. Disbelief in vaccine effectiveness (against infection: OR 3.69, CI 1.98, 6.90; serious illness: OR 3.15, CI 1.69, 5.86), disagreeing with government decision-making (somewhat disagree: OR 2.70, CI 1.38, 5.29; strongly disagree: OR 4.62, CI 2.20, 9.7), and beliefs in over-vaccinating (OR 2.07, CI 1.53, 2.80) were found associated with booster dose hesitancy. CONCLUSION: COVID-19 vaccine hesitancy may develop or increase regarding subsequent vaccines. Our findings indicate factors to consider when targeting vaccine-hesitant populations.

RéSUMé: OBJECTIF: La transmission de la COVID-19, l'émergence de variants préoccupants et l'affaiblissement de l'immunité ont conduit à recommander des doses de rappel de vaccin contre la COVID-19. L'hésitation à la vaccination remet en question une large couverture vaccinale. Nous avons déployé une enquête transnationale pour étudier les connaissances, les croyances et les comportements en faveur de la poursuite de la vaccination contre la COVID-19. MéTHODES: Nous avons mené une enquête nationale transversale en ligne auprès d'adultes au Canada, entre le 16 et le 26 mars 2022. Nous avons utilisé des statistiques descriptives pour résumer notre échantillon et testé les différences démographiques, les perceptions de l'efficacité des vaccins, les doses recommandées et la confiance dans les décisions, en utilisant la correction de Rao-Scott pour les tests du chi carré pondérés. La régression logistique multivariée a été ajustée pour les covariables pertinentes afin d'identifier les facteurs sociodémographiques et les croyances associés à l'hésitation à la vaccination. RéSULTATS: Nous avons collecté 2 202 questionnaires remplis. Un faible niveau d'éducation (lycée : rapport de cotes (OR) 1,90, intervalle de confiance (IC) à 95% 1,29, 2,81) et le fait d'avoir des enfants (OR 1,89, IC 1,39, 2,57) étaient associés à une probabilité accrue d'éprouver une hésitation à l'égard d'une dose de rappel, tandis qu'un revenu plus élevé (100 000 $­149 999 $ : OR 0,60, IC 0,39, 0,91; 150 000 $ ou plus : OR 0,49, IC 0,29, 0,82) était associé à une diminution des probabilités. Incrédulité dans l'efficacité du vaccin (contre l'infection : OR 3,69, IC 1,98, 6,90; maladie grave : OR 3,15, IC 1,69, 5,86), en désaccord avec la prise de décision du gouvernement (plutôt en désaccord : OR 2,70, IC 1,38, 5,29; fortement en désaccord : OR 4,62, IC 2,20, 9,7) et la croyance dans le sur-vaccination (OR 2,07, IC 1,53, 2,80) ont été associées à une hésitation à recevoir une dose de rappel. CONCLUSION: Une hésitation à l'égard du vaccin contre la COVID-19 peut se développer ou augmenter à l'égard des vaccins ultérieurs. Nos résultats indiquent des facteurs à prendre en compte lors du ciblage des populations hésitantes à la vaccination.

Sleep, Circadian Rhythms, and Cognitive Dysfunction in Huntington's Disease.

BACKGROUND: In healthy people, sleep and circadian disruption are linked to cognitive deficits. People with Huntington's disease (HD), who have compromised brain function and sleep and circadian disturbances, may be even more susceptible to these cognitive effects. OBJECTIVE: To conduct a comprehensive review and synthesis of the literature in HD on the associations of cognitive dysfunction with disturbed sleep and circadian rhythms. METHODS: We searched MEDLINE via OVID, CINAHL Plus, EMBASE via OVID, and PubMed in May 2023. The first author then screened by title and abstract and conducted a full review of remaining articles. RESULTS: Eight studies investigating the influence of sleep and/or circadian rhythms on cognitive function in HD were found. In manifest HD, poorer sleep was associated with worse cognitive function. For behavioral 24-hour (circadian) rhythms, two studies indicated that later wake times correlated with poorer cognitive function. No reported studies in HD examined altered physiological 24-hour (circadian) rhythms and cognitive impairment. CONCLUSION: Some associations exist between poor sleep and cognitive dysfunction in manifest HD, yet whether these associations are present before clinical diagnosis is unknown. Whether circadian disturbances relate to cognitive impairment in HD also remains undetermined. To inform sleep and circadian interventions aimed at improving cognitive symptoms in HD, future research should include a range of disease stages, control for external factors, and utilize robust cognitive batteries targeted to the aspects of cognitive function known to be adversely affected in HD.

Identification of herbarium specimen sheet components from high-resolution images using deep learning.

Advanced computer vision techniques hold the potential to mobilise vast quantities of biodiversity data by facilitating the rapid extraction of text- and trait-based data from herbarium specimen digital images, and to increase the efficiency and accuracy of downstream data capture during digitisation. This investigation developed an object detection model using YOLOv5 and digitised collection images from the University of Melbourne Herbarium (MELU). The MELU-trained 'sheet-component' model-trained on 3371 annotated images, validated on 1000 annotated images, run using 'large' model type, at 640 pixels, for 200 epochs-successfully identified most of the 11 component types of the digital specimen images, with an overall model precision measure of 0.983, recall of 0.969 and moving average precision (mAP0.5-0.95) of 0.847. Specifically, 'institutional' and 'annotation' labels were predicted with mAP0.5-0.95 of 0.970 and 0.878 respectively. It was found that annotating at least 2000 images was required to train an adequate model, likely due to the heterogeneity of specimen sheets. The full model was then applied to selected specimens from nine global herbaria (Biodiversity Data Journal, 7, 2019), quantifying its generalisability: for example, the 'institutional label' was identified with mAP0.5-0.95 of between 0.68 and 0.89 across the various herbaria. Further detailed study demonstrated that starting with the MELU-model weights and retraining for as few as 50 epochs on 30 additional annotated images was sufficient to enable the prediction of a previously unseen component. As many herbaria are resource-constrained, the MELU-trained 'sheet-component' model weights are made available and application encouraged.

A North Star Vision: Results from a Deliberative Dialogue to Identify Policy Strategies to Improve Value in Healthcare.

We hosted a deliberative dialogue with citizens (n = 3), policy researchers (n = 3), government decision makers (n = 3) and health system leaders (n = 3) to identify evidence-informed policy options to improve the value of Canadian healthcare. The analysis resulted in three themes: (1) the need for a vision to guide reforms, (2) community-based care and (3) community-engaged care. Results suggest the need for a new paradigm: community-focused health systems. Such a paradigm could serve as a North Star guiding healthcare transformation, improving value by aligning citizen and healthcare system goals, prioritizing spending on services that address the social determinants of health and improving quality and equity.

Interventions to improve well-being among children and youth aged 6-17 years during the COVID-19 pandemic: a systematic review.

BACKGROUND: The COVID-19 pandemic is an example of a global infectious disease outbreak that poses a threat to the well-being of children and youth (e.g., physical infection, psychological impacts). The consequences of challenges faced during COVID-19 may be longstanding and newly developed interventions are being deployed. We present a narrative synthesis of available evidence from the first 2 years of the COVID-19 pandemic on the feasibility, accessibility, and effects of interventions to improve well-being among children and youth to inform the development and refinement of interventions relevant to post-pandemic recovery. METHODS: Six databases were searched from inception to August 2022. A total of 5484 records were screened, 39 were reviewed in full text, and 19 studies were included. The definition of well-being and the five domains of well-being as defined by the Partnership for Maternal, Newborn & Child Health and the World Health Organization in collaboration with the United Nations H6 + Technical Working Group on Adolescent Health and Well-Being were used. RESULTS: Nineteen studies (74% randomized controlled trials) from 10 countries were identified, involving a total of 7492 children and youth (age range: 8.2-17.2 years; 27.8-75.2% males) and 954 parents that occurred during the COVID-19 pandemic (March 2020 to March 2021). Nearly all interventions (n = 18, 95%) targeted health and nutrition, followed by connectedness (n = 6, 32%), while fewer studies targeted agency and resilience (n = 5, 23%), learning and competence (n = 2, 11%), or safety and support (n = 1, 3%). Five interventions (26%) were self-guided while 13 interventions (68%) were guided synchronous by a trained professional, all of which targeted physical and mental health subdomains within health and nutrition; one intervention (5%) was unclear. CONCLUSIONS: Studies deploying synchronous interventions most often reported improved well-being among children and youth largely in the domain of health and nutrition, specifically physical and mental health. Targeted approaches will be crucial to reach sub-groups of children and youth who are most at risk of negative well-being outcomes. Further research is needed to determine how interventions that best supported children and youth early in the pandemic are different from interventions that are required now as we enter into the post-pandemic phase.

Exploring the influence of behavioural, normative and control beliefs on intentions to adhere to public health guidelines during the COVID-19 pandemic: a qualitative interview based study.

BACKGROUND: Perceived severity and susceptibility of disease are predictors of individual behaviour during health crises. Little is known about how individual beliefs influence intentions to adhere to public health guidelines during periods of health crises, and how access to and consumption of information influence these intentions. This study investigated behavioural beliefs, normative beliefs, and control beliefs, and their influence on behavioural intentions to adhere to public health guidelines during the COVID-19 pandemic. METHODS: Participants were recruited from a related COVID-19 study conducted by our team, and through snowball sampling in subsequent. Using a maximum variation sampling technique, we recruited a diverse group of participants representing six major regions in Canada. Participants took part in one-on-one semi-structured interviews from February 2021 to May 2021. Data were analyzed independently in duplicate by thematic analysis. The Theory of Planned Behaviour (TPB) was the conceptual framework used to organize dominant themes. RESULTS: We conducted a total of 60 individual interviews (137 eligible individuals contacted, 43.8% response rate) and identified six themes organized according to the three constructs of behavioural, normative and control beliefs as described in the TPB: (1) Behavioural: My "New Normal," Individual Rights and Perceived Pandemic Severity, Fatigue with COVID-19, (2) Normative: COVID-19 Collective, (3) Control: Practicality of Public Health Guidelines, and (6) Conflicting Public Health Messages. Most (n = 43, 71.7%) participants perceived individuals in their geographic community to be following public health guidelines adequately. Several participants (n = 15, 25.0%) commented on the unequal impact of restrictions based on socioeconomic factors (i.e., class, race, age). CONCLUSION: Individual perceptions of risk, loss of control, access to resources (i.e., childcare), and societal expectations, shaped intentions to engage in disease preventative behaviours (i.e., social distancing) during the COVID-19 pandemic.

The impact of the COVID-19 pandemic on primary care physicians and nurses in Nova Scotia: a qualitative exploratory study.

BACKGROUND: The COVID-19 pandemic has brought immense disruption worldwide, dramatically altering the ways we live, work and learn on a day-to-day basis; however, few studies have investigated this from the perspective of primary care providers. In this study, we sought to explore the experiences of primary care providers in the province of Nova Scotia, with the intention of understanding the impact of the COVID-19 pandemic on primary care providers' ability to provide care, their information pathways, and the personal and professional impact of the pandemic. METHODS: We conducted an exploratory qualitative research study involving semistructured interviews conducted via Zoom videoconferencing or telephone with primary care providers (physicians, nurse practitioners and family practice nurses) who self-identified as working in primary health care in Nova Scotia from June 2020 to April 2021. We performed a thematic analysis involving coding and classifying data according to themes. Emergent themes were then interpreted by seeking commonalties, divergence, relationships and overarching patterns in the data. RESULTS: Twenty-four primary care providers were interviewed. Subsequent analysis identified 4 interrelated themes within the data: disruption to work-life balance, disruptions to "non-COVID-19" patient care, impact of provincial and centralized policies, and filtering and processing an influx of information. INTERPRETATION: Our findings showed that managing a crisis of this magnitude requires coordination and new ways of working, balancing professional and personal life, and adapting to already implemented changes (i.e., virtual care). A specific primary care pandemic response plan is essential to mitigate the impact of future health care crises.

Biomimetic multi-channel microstimulation of somatosensory cortex conveys high resolution force feedback for bionic hands.

Manual interactions with objects are supported by tactile signals from the hand. This tactile feedback can be restored in brain-controlled bionic hands via intracortical microstimulation (ICMS) of somatosensory cortex (S1). In ICMS-based tactile feedback, contact force can be signaled by modulating the stimulation intensity based on the output of force sensors on the bionic hand, which in turn modulates the perceived magnitude of the sensation. In the present study, we gauged the dynamic range and precision of ICMS-based force feedback in three human participants implanted with arrays of microelectrodes in S1. To this end, we measured the increases in sensation magnitude resulting from increases in ICMS amplitude and participant's ability to distinguish between different intensity levels. We then assessed whether we could improve the fidelity of this feedback by implementing "biomimetic" ICMS-trains, designed to evoke patterns of neuronal activity that more closely mimic those in natural touch, and by delivering ICMS through multiple channels at once. We found that multi-channel biomimetic ICMS gives rise to stronger and more distinguishable sensations than does its single-channel counterpart. Finally, we implemented biomimetic multi-channel feedback in a bionic hand and had the participant perform a compliance discrimination task. We found that biomimetic multi-channel tactile feedback yielded improved discrimination over its single-channel linear counterpart. We conclude that multi-channel biomimetic ICMS conveys finely graded force feedback that more closely approximates the sensitivity conferred by natural touch.

Prioritizing outcome measures after aneurysmal subarachnoid hemorrhage: A q-sort survey of patients, health care providers and researchers.

Objective: To understand which outcome measures patients and their families, health care providers, and researchers prioritize after aneurysmal subarachnoid hemorrhage (aSAH). Methods: We conducted a cross-sectional q-sort survey with participants from three key stakeholder groups. Potential outcomes were identified from interviews and focus groups. Participants were purposively sampled to achieve diversity based on stakeholder group, geography, and profession. Respondents sorted 27 outcomes in a quasi-normally distributed grid (Q-Sort) from most to least important. Principal components analysis was used to determine similarities in the way participants sorted the outcome measures resulting in distinct groupings. Overall rankings were also reported. Results: 112 participants were invited. 70 responded and 64 participants from 25 different countries completed a Q-sort. Balanced stakeholder representation was achieved. Five distinct patterns were identified based on survival, pathophysiological, psychological, resource use, and functional outcome measures. Quality of life as reported by the patient was the highest ranked outcome measure followed by independence and functional measures. Survival and biomedical outcomes were ranked in the middle and cost measures last. Conclusions: In this diverse sample of key stakeholders, we characterized several distinct perspectives with respect to outcome measure selection in aSAH. We did not identify a clear pattern of opinion based on stakeholder group or other participant characteristics. Patient-reported measure of quality of life was ranked the most important overall with function and independence also highly rated. These results will assist study design and inform efforts to improve outcome selection in aSAH research.

Sox9 Expression in the Second Heart Field; A Morphological Assessment of the Importance to Cardiac Development with Emphasis on Atrioventricular Septation.

Failure to form the septal structures that separate the left and right cardiac chambers results in defects that allow shunting of blood from one side of the heart to the other, leading to the mixing of oxygenated and de-oxygenated blood. The atrioventricular (AV) mesenchymal complex, consisting of the AV cushions, the Dorsal Mesenchymal Protrusion (DMP), and the mesenchymal cap, plays a crucial role in AV septation. Cells found in these structures derive from different cell lineages. In this study we have investigated the role of the transcription factor Sox9 in the Second Heart Field (SHF) with the emphasis on the formation of the atrioventricular septal complex. Using a mouse model in which Sox9 is conditionally deleted from the SHF we demonstrate that in this model virtually all mouse embryos develop septal abnormalities, including complete atrioventricular septal defects (cAVSDs) and isolated ventricular septal defects. Our morphological analyses indicate that perturbation of the development of the mesenchymal cap appears to play a crucial role in the pathogenesis of the atrial septal defects observed in the AVSDs and suggests that this component of the AV mesenchymal complex might play a more important role in AV septation than previously appreciated.

Examining the development and utilization of infection control policies to safely support adults with intellectual and developmental disabilities in congregate living settings during COVID-19.

OBJECTIVE: Congregate living settings supporting individuals with intellectual and developmental disabilities (IDD) have experienced unprecedented challenges during the COVID-19 pandemic. This study aimed to explore the development and utilization of infection control policies in congregate living settings supporting individuals with IDD during the COVID-19 pandemic. METHODS: This qualitative study employed an interpretive description using semi-structured interviews involving administrative personnel from agencies assisting those with IDD residing in Developmental Services congregate living settings in Ontario, Canada. RESULTS: Twenty-two semi-structured interviews were conducted with individuals from 22 agencies. Thematic analysis revealed three categories: Development of infection control policies, Implementation of infection control policies, and Impact of infection control policies. Each category yielded subsequent themes. Themes from the Development of infection control policies category included New responsibilities and interpreting the grey areas, and Feeling disconnected and forgotten. Four themes within the Implementation of infection control policies category included, "It's their home" (i.e. difficulty balancing public health guidance and organizational values), Finding equipment and resources (e.g. supports and barriers), Information overload (i.e. challenges agencies faced when implementing policies), and Emerging vaccination (i.e. perspective of agencies as they navigate vaccination for clients and staff). The category of Impact of infection control policies had one theme-Fatigue and burnout, capturing the impact of policies on stakeholders in congregate living settings. CONCLUSION: Agencies experienced difficulties developing and implementing infection control policies, impacting the clients they serve and their families and staff. Public health guidance should be tailored to each congregate living setting rather than generally applied.

RéSUMé: OBJECTIF: Les lieux d'hébergement collectif pour les personnes ayant une déficience intellectuelle ou de développement (DID) ont affronté des défis sans précédent durant la pandémie de la COVID-19. La présente étude vise à explorer l'élaboration et l'utilisation des politiques de prévention des infections dans les lieux d'hébergement collectif pour les personnes ayant une DID durant la pandémie de la COVID-19. MéTHODES: Cette étude qualitative repose sur la description interprétative lors d'entrevues semi-structurées auprès du personnel administratif des organismes qui viennent en aide aux personnes ayant une DID et résidant dans des lieux d'hébergement collectif en Ontario, au Canada. RéSULTATS: Au total, 22 entrevues semi-structurées ont été effectuées auprès de personnes provenant de 22 organismes. L'analyse thématique a révélé trois catégories : Élaboration des politiques de prévention des infections, mise en œuvre des politiques de prévention des infections, et impacts des politiques de prévention des infections. Chaque catégorie a généré des thèmes subséquents. Les thèmes liés à l'élaboration des politiques de prévention des infections comprenaient les nouvelles responsabilités et l'interprétation des zones grises, et le sentiment de détachement et d'avoir été oublié. Quatre thèmes découlant de la mise en œuvre des politiques de prévention des infections comprenaient « c'est leur maison ¼ (c'est-à-dire difficulté d'équilibrer les mesures de santé publique et les valeurs organisationnelles), trouver de l'équipement et des ressources (p. ex., mesures de soutien et obstacles), surcharge d'information (c'est-à-dire les défis qu'ont dû affronter les organismes lors de la mise en œuvre des politiques) et la vaccination émergente (notamment la perspective des organismes lorsqu'ils ont dû composer avec le processus de vaccination pour la clientèle et le personnel). La catégorie des impacts des politiques de prévention des infections avait un thème : la fatigue et l'épuisement professionnel, saisissant les impacts des politiques de prévention des infections dans les lieux d'hébergement collectif sur ses intervenants. CONCLUSION: Les organismes ont éprouvé des difficultés lors de l'élaboration et la mise en œuvre de politiques de prévention des infections, touchant ainsi leurs clients, leurs familles et leurs employés. Les mesures de santé publique devraient plutôt être adaptées à chaque lieu d'hébergement collectif, et non pas appliquées de façon générale.

Clinical utility of circulating calprotectin to assist prediction and monitoring of COVID-19 severity: An Italian study.

BACKGROUND: Calprotectin (S100A8/A9) has been identified as a biomarker that can aid in predicting the severity of disease in COVID-19 patients. This study aims to evaluate the correlation between levels of circulating calprotectin (cCP) and the severity of COVID-19. METHODS: Sera from 245 COVID-19 patients and 110 apparently healthy individuals were tested for calprotectin levels using a chemiluminescent immunoassay (Inova Diagnostics). Intensive care unit (ICU) admission and type of respiratory support administered were used as indicators of disease severity, and their correlation with calprotectin levels was assessed. RESULTS: Samples from patients in the ICU had a median calprotectin concentration of 11.6 µg/ml as compared to 3.5 µg/ml from COVID-19 patients who were not in the ICU. The median calprotectin concentration in a cohort of healthy individuals collected before the COVID-19 pandemic was 3.0 µg/ml (95% CI: 2.820-2.969 µg/ml). Patients requiring a Venturi mask, continuous positive airway pressure, or orotracheal intubation all had significantly higher values of calprotectin than controls, with the increase of cCP levels proportional to the increasing need of respiratory support. CONCLUSION: Calprotectin levels in serum correlate well with disease severity and represent a promising serological biomarker for the risk assessment of COVID-19 patients.

Strategies to mitigate the impact of the COVID-19 pandemic on child and youth well-being: a scoping review protocol.

INTRODUCTION: Children and youth are often more vulnerable than adults to emotional impacts of trauma. Wide-ranging negative effects (eg, social isolation, lack of physical activity) of the COVID-19 pandemic on children and youth are well established. This scoping review will identify, describe and categorise strategies taken to mitigate potentially deleterious impacts of the COVID-19 pandemic on children, youth and their families. METHODS AND ANALYSIS: We will conduct a scoping review following the Arksey-O'Malley five-stage scoping review method and the Scoping Review Methods Manual by the Joanna Briggs Institute. Well-being will be operationalised according to pre-established domains (health and nutrition, connectedness, safety and support, learning and competence, and agency and resilience). Articles in all languages for this review will be identified in CINAHL, Cochrane CENTRAL Register of Controlled Trials, EMBASE, ERIC, Education Research Complete, MEDLINE and APA PsycINFO. The search strategy will be restricted to articles published on or after 1 December 2019. We will include primary empirical and non-empirical methodologies, excluding protocols, reports, opinions and editorials, to identify new data for a broad range of strategies to mitigate potentially deleterious impacts of the COVID-19 pandemic on child and youth well-being. Two reviewers will calibrate screening criteria and the data abstraction form and will independently screen records and abstract data. Data synthesis will be performed according to the convergent integrated approach described by the Joanna Briggs Institute. ETHICS AND DISSEMINATION: Ethical approval is not applicable as this review will be conducted on published data. Findings of this study will be disseminated at national and international conferences and will inform our pan-Canadian multidisciplinary team of researchers, public, health professionals and knowledge users to codesign and pilot test a digital psychoeducational health tool-an interactive, web-based tool to help Canadian youth and their families address poor mental well-being resulting from and persisting beyond the COVID-19 pandemic.

Lived experiences of Asian Canadians encountering discrimination during the COVID-19 pandemic: a qualitative interview study.

BACKGROUND: Asian Canadians have experienced increased cases of racialized discrimination after the first emergence of SARS-CoV-2 in China. This study examined how the COVID-19 pandemic has affected Asian Canadians' sense of safety and belonging in their Canadian (i.e., geographical) communities. METHODS: We applied a qualitative description study design in which semistructured interviews were conducted from Mar. 23 to May 27, 2021. Purposive and snowball sampling methods were used to recruit Asian Canadians diverse in region, gender and age. Interviews were conducted through Zoom videoconference or telephone, and independent qualitative thematic analysis in duplicate was used to derive primary themes and subthemes. RESULTS: Thirty-two Asian Canadians (median age 35 [interquartile range 24-46] yr, 56% female, 44% East Asian) participated in the study. We identified 5 predominant themes associated with how the COVID-19 pandemic affected the participants' sense of security and belonging to their communities: relation between socioeconomic status (SES) and exposure to discrimination (i.e., how SES insulates or exposes individuals to increased discrimination); politics, media and the COVID-19 pandemic (i.e., the key role that politicians and media played in enabling spread of discrimination against and fear of Asian people); effect of discrimination on mental and social health (i.e., people's ability to interact and form meaningful relationships with others); coping with the impact of discrimination (i.e., the way people appraise and move forward in identity-threatening situations); and implications for sense of safety and sense of belonging (i.e., people feeling unable to safely use public spaces in person, including the need to remain alert in anticipation of harm, leading to distress and exhaustion). INTERPRETATION: During the COVID-19 pandemic, Asian Canadians in our study felt unsafe owing to the uncertain, unexpected and unpredictable nature of discrimination, but also felt a strong sense of belonging to Canadian society and felt well connected to their Asian Canadian communities. Future work should seek to explore the influence of social media on treatment of and attitudes toward Asian Canadians.

Patient and family involvement in Choosing Wisely initiatives: a mixed methods study.

BACKGROUND: Patients are important stakeholders in reducing low-value care, yet mechanisms for optimizing their involvement in low-value care remain unclear. To explore the role of patients in the development and implementation of Choosing Wisely recommendations to reduce low-value care and to assess the likelihood that existing patient resources will change patient health behaviour. METHODS: Three phased mixed-methods study: 1) content analysis of all publicly available Choosing Wisely clinician lists and patient resources from the United States of America and Canada. Quantitative data was summarized with frequencies and free text comments were analyzed with qualitative thematic content analysis; 2) semi-structured telephone interviews with a purposive sample of representatives of professional societies who created Choosing Wisely clinician lists and members of the public (including patients and family members). Interviews were transcribed verbatim, and two researchers conducted qualitative template analysis; 3) evaluation of Choosing Wisely patient resources. Two public partners were identified through the Calgary Critical Care Research Network and independently answered two free text questions "would this change your health behaviour" and "would you discuss this material with a healthcare provider". Free text data was analyzed by two researchers using thematic content analysis. RESULTS: From the content analysis of 136 Choosing Wisely clinician lists, six reported patient involvement in their development. From 148 patient resource documents that were mapped onto a conceptual framework (Inform, Activate, Collaborate) 64% described patient engagement at the level of Inform (educating patients). From 19 interviews stakeholder perceptions of patient involvement in reducing low-value care were captured by four themes: 1) impact of perceived power dynamics on the discussion of low-value care in the clinical interaction, 2) how to communicate about low-value care, 3) perceived barriers to patient involvement in reducing low-value care, and 4) suggested strategies to engage patients and families in Choosing Wisely initiatives. In the final phase of work in response to the question "would this change your health behaviour" two patient partners agreed 'yes' on 27% of patient resources. CONCLUSIONS: Opportunities exist to increase patient and family participation in initiatives to reduce low-value care.

Public perceptions during the first wave of the COVID-19 pandemic in Canada: a demographic analysis of self-reported beliefs, behaviors, and information acquisition.

INTRODUCTION: We explored associations between sociodemographic factors and public beliefs, behaviors, and information acquisition related to the coronavirus disease 2019 (COVID-19) to identify how the experiences of subpopulations in Canada may vary. METHODS: We administered a national online survey through Ipsos Incorporated to adults residing in Canada. Sampling was stratified by population age, sex, and regional distributions. We used descriptive statistics to summarize responses and test for differences based on gender, age, educational attainment, and household income using chi-squared tests, followed by weighted logistic regression. RESULTS: We collected 1996 eligible questionnaires between April 26th and May 1st, 2020. Respondents mean age was 50 years, 51% were women, 56% had a post-secondary degree, and 72% had a household income <$100,000. Our analysis found differences within the four demographic groups, with age effects most acutely evidenced. Respondents 65 years and older were more likely to perceive the pandemic as very serious, less likely to report declines in overall health, and more likely to intend to get vaccinated, compared to 18-29 year olds. Women overall were more likely to report negative outcomes than men, including stress due to the pandemic, and worsening social, mental/emotional, and spiritual health. Respondents 45 and older were more likely to seek and trust information from traditional Canadian news sources, while 18-29 year olds were more likely to seek and trust information on social media; overall, women and respondents with a post-secondary degree were more likely to access and trust online information from public health sites. CONCLUSION: This study found important demographic differences in how adults living in Canada perceived the COVID-19 pandemic, the impacts on their health, and their preferences for information acquisition. Our results highlight the need to consider demographic characteristics in tailoring the format and information medium to improve large scale acceptance and uptake of mitigation and containment measures.
