ABSTRACT

Both adverse childhood experiences (ACEs) and perceived discrimination have been found to impact mental health in adults, but less is understood about the ways they interact to affect anxiety and depression symptoms. In the spring and summer of 2020, there were large societal changes stemming from the COVID-19 pandemic and social and racial justice movements in the United States. The current study aimed to characterize the interactive associations of ACE history and perceived discrimination with mental health in a sample of college students assessed prior to the pandemic in the fall of 2019 and then again in the fall of 2020. Results showed that in 2019, greater discrimination and more ACEs were associated with greater anxiety/depression symptoms. In 2020, a negative interactive effect of ACE history and discrimination on mental health was found, such that for individuals with low ACEs, greater discrimination was associated with significantly greater anxiety/depression symptoms. We also found that increases in perceived discrimination from 2019 to 2020 were significantly positively associated with increases in anxiety/depression symptoms over that same time period. The findings highlight the significant impacts that both ACEs history and perceived discrimination have on mental health and suggest that experiences of discrimination should be thought of as a critical, dynamic factor impacting college students' mental health.

ABSTRACT

This commentary offers an analysis of the implications of Covid-19 on the future of elite women's football, with the intention of reflecting on and illuminating the threat and uncertainty facing the game. Topics covered include (1) organisational and economic repercussions;(2) consequences for player contracts, migration and investment;and (3) player wellbeing. These significant challenges require swift and decisive action in order to mitigate their potential effects. Recommendations are made for governing bodies, parent clubs and practitioners, in addition to possible future research directions for academics. We reflect upon what can be done during and post-pandemic to continue the momentum and growth of women's football in England, highlighting the need for football clubs to learn from previous crises by embracing innovation and entrepreneurship.

ABSTRACT

We present the outcomes from the reaudit of an established UK regional teledermatology service, revealing the impact of the COVID-19 pandemic on referrals from primary to secondary care. Our teledermatology service invites general practitioners (GPs) to submit queries with attached clinical photographs regarding adult patients through the National Health Service EReferral Service. While requests in relation to skin lesions are not excluded, GPs are advised to continue referring suspected skin cancers through the usual 2-week-wait (2WW) pathway. The original audit involved data collection over 12 months before the COVID-19 pandemic. It demonstrated a functioning service providing rapid advice and guidance responses to GPs from consultant dermatologists or associate specialists. The service was reaudited over a 1-month period during the COVID-19 pandemic. Data were collected on the time taken to get a response, the types of dermatological problems in question, the quality of photos submitted and the response outcome. In October 2020, 273 requests were submitted to the service, revealing a 4.5-fold increase vs. pre-COVID-19 pandemic queries. The average response time was 0 08 days. Further referral to secondary care was advised in 20% of cases, with 26% of patients ultimately being referred in the subsequent 3 months. Forty per cent of queries related to skin lesions, a further 40% to chronic dermatoses, 14% to acute dermatoses and 4% to provide advice on therapeutic management. Most notably, there was a six-factor increase in skin lesion queries when compared with pre-COVID-19 data. Our reaudit demonstrated a teledermatology service that continues to deliver timely advice, with the vast majority of responses provided on the same day as the request. This both preserves resources in avoiding potential referrals to secondary care and saves patients from long waiting times for an outpatient appointment. The demand for teledermatology advice has risen significantly during the COVID-19 pandemic, particularly with regard to skin lesions. This may be explained by the current reduced capacity for GPs to see their patients face to face or by the initial reduction in 2WW referrals made at the beginning of the pandemic and subsequent catch-up. The proportion of response outcomes advising further referral for an outpatient appointment has also increased during the pandemic. This is often due to inappropriate queries better served by the skin cancer pathway. Furthermore, 60% of requests lacked good-quality photographs or dermoscopic images, which often left the responding clinician unable to make an adequate assessment of a skin lesion, therefore resulting in referral.

ABSTRACT

Academic surgery has changed along with the rest of the world in response to the COVID pandemic. With increasing rates of vaccination against COVID over the past 2 y, we have slowly but steadily made progress toward controlling the spread of the virus. Surgeons, academic surgery departments, health systems, and trainees are all attempting to establish a new normal in various domains-clinical, research, teaching, and in their personal lives. How has the pandemic changed these areas? At the 2022 Academic Surgical Congress Hot Topics session, we attempted to address these issues.

ABSTRACT

BACKGROUND: The COVID-19 pandemic has affected people's lives beyond severe and long-term physical health symptoms. Social distancing and quarantine have led to adverse mental health outcomes. COVID-19-induced economic setbacks have also likely exacerbated the psychological distress affecting broader aspects of physical and mental well-being. Remote digital health studies can provide information about the pandemic's socioeconomic, mental, and physical impact. COVIDsmart was a collaborative effort to deploy a complex digital health research study to understand the impact of the pandemic on diverse populations. We describe how digital tools were used to capture the effects of the pandemic on the overall well-being of diverse communities across large geographical areas within the state of Virginia. OBJECTIVE: The aim is to describe the digital recruitment strategies and data collection tools applied in the COVIDsmart study and share the preliminary study results. METHODS: COVIDsmart conducted digital recruitment, e-Consent, and survey collection through a Health Insurance Portability and Accountability Act-compliant digital health platform. This is an alternative to the traditional in-person recruitment and onboarding method used for studies. Participants in Virginia were actively recruited over 3 months using widespread digital marketing strategies. Six months of data were collected remotely on participant demographics, COVID-19 clinical parameters, health perceptions, mental and physical health, resilience, vaccination status, education or work functioning, social or family functioning, and economic impact. Data were collected using validated questionnaires or surveys, completed in a cyclical fashion and reviewed by an expert panel. To retain a high level of engagement throughout the study, participants were incentivized to stay enrolled and complete more surveys to further their chances of receiving a monthly gift card and one of multiple grand prizes. RESULTS: Virtual recruitment demonstrated relatively high rates of interest in Virginia (N=3737), and 782 (21.1%) consented to participate in the study. The most successful recruitment technique was the effective use of newsletters or emails (n=326, 41.7%). The primary reason for contributing as a study participant was advancing research (n=625, 79.9%), followed by the need to give back to their community (n=507, 64.8%). Incentives were only reported as a reason among 21% (n=164) of the consented participants. Overall, the primary reason for contributing as a study participant was attributed to altruism at 88.6% (n=693). CONCLUSIONS: The COVID-19 pandemic has accelerated the need for digital transformation in research. COVIDsmart is a statewide prospective cohort to study the impact of COVID-19 on Virginians' social, physical, and mental health. The study design, project management, and collaborative efforts led to the development of effective digital recruitment, enrollment, and data collection strategies to evaluate the pandemic's effects on a large, diverse population. These findings may inform effective recruitment techniques across diverse communities and participants' interest in remote digital health studies.

ABSTRACT

The Black Lives Matter movement and coronavirus pandemic have raised awareness of society's categorisation of non-white people and institutional language used. We add to contemporary debate on the BAME acronym (Black, Asian and minority ethnic) by providing a critical examination of the perceptions and attitudes towards it in the UK. Drawing on in-depth interviews with women from these communities who were working in the hyper-masculinised and white-dominated sporting industry, we privilege the voices of those who traditionally have been omitted. Adopting a Critical Race Theory approach and an intersectional lens three overarching themes were identified: rejection and indifference towards the BAME acronym;filling in the form – inadequacies of the system;and, making up the quota – perpetuating (work-related) insecurity(ies). The findings provide analytical insight into institutional language and highlight the potential for the BAME acronym to cause distress and alienation while preserving the concept of Whiteness.

ABSTRACT

Background: There are groups in our community who may be more vulnerable to contracting, transmitting, or experiencing negative health impacts of COVID-19 than the general community. They may also have greater difficulty accessing, accepting, and acting upon COVID-19 public health information. Our aim was to understand if vulnerable communities and those who express "COVID-risk" behavioural intentions seek and respond differently to COVID-19 public health information. Methods: This observational, cross-sectional study recruited adults aged over 18 years from the Australian general community and six community groups (people with disabilities and their caregivers, Aboriginal and Torres Strait Islanders, aged care workers, street-based sex workers, refugees and asylum seekers, and the deaf and hard of hearing). We investigated attitudes and beliefs about COVID-19 public health messages. We identified factors associated with the respondent's perception of the ease of finding information and understanding it, and its relevance to them. We also examined latent classes that were developed based on attitudes to public health measures and vulnerable group categories, along with demographic variables. Results: We received 1444 responses (n = 1121 general community; n ≥50 for each vulnerable group). The vulnerable groups examined found COVID-19 public health messages as easy, if not easier, to find and understand than the general community. Four latent classes were identified: COVID-safe mask wearers (10% of sample), COVID-safe test takers (56%), COVID-risk isolators (19%) and COVID-risk visitors (15%). The COVID-risk classes (34% of sample) were less likely to consider COVID-19 information easy to find, understandable, and relevant. Conclusions: Additional public health messaging strategies may be needed for targeting people with "COVID-risk" beliefs and attitudes who appear across the community (general and vulnerable groups) rather than just targeting specific cultural or other groupings that we think may be vulnerable. COVID-risk classes identified through this study were not defined by demographic characteristics or cultural groupings, but were spread across vulnerable communities and the general community. Different approaches for tailoring and delivery of specific public health information for these groups are needed.

ABSTRACT

The pro- and anti-inflammatory pathways that determine the balance of inflammation and viral control during SARS-CoV-2 infection are not well understood. Here we examine the roles of IFN{gamma} and IL-10 in regulating inflammation, immune cell responses and viral replication during SARS-CoV-2 infection of rhesus macaques. IFN{gamma} blockade tended to decrease lung inflammation based on 18FDG-PET/CT imaging but had no major impact on innate lymphocytes, neutralizing antibodies, or antigen-specific T cells. In contrast, IL-10 blockade transiently increased lung inflammation and enhanced accumulation of virus-specific T cells in the lower airways. However, IL-10 blockade also inhibited the differentiation of virus-specific T cells into airway CD69+CD103+ TRM cells. While virus-specific T cells were undetectable in the nasal mucosa of all groups, IL-10 blockade similarly reduced the frequency of total TRM cells in the nasal mucosa. Neither cytokine blockade substantially affected viral load and infection ultimately resolved. Thus, in the macaque model of mild COVID-19, the pro- and anti-inflammatory effects of IFN{gamma} and IL-10 have no major role in control of viral replication. However, IL-10 has a key role in suppressing the accumulation of SARS-CoV-2-specific T cells in the lower airways, while also promoting TRM at respiratory mucosal surfaces.

ABSTRACT

Importance: The COVID-19 pandemic is associated with decreased surgical procedure volumes, but existing studies have not investigated this association beyond the end of 2020, analyzed changes during the post-vaccine release period, or quantified these changes by patient acuity. Objective: To quantify changes in the volume of surgical procedures at a 1017-bed academic quaternary care center from January 6, 2019, to December 31, 2021. Design, Setting, and Participants: In this cohort study, 129 596 surgical procedure volumes were retrospectively analyzed during 4 periods: pre-COVID-19 (January 6, 2019, to January 4, 2020), COVID-19 peak (March 15, 2020, to May 2, 2020), post-COVID-19 peak (May 3, 2020, to January 2, 2021), and post-vaccine release (January 3, 2021, to December 31, 2021). Surgery volumes were analyzed by subspecialty and case class (elective, emergent, nonurgent, urgent). Statistical analysis was by autoregressive integrated moving average modeling. Main Outcomes and Measures: The primary outcome of this study was the change in weekly surgical procedure volume across the 4 COVID-19 periods. Results: A total of 129 596 records of surgical procedures were reviewed. During the COVID-19 peak, overall weekly surgical procedure volumes (mean [SD] procedures per week, 406.00 [171.45]; 95% CI, 234.56-577.46) declined 44.6% from pre-COVID-19 levels (mean [SD] procedures per week, 732.37 [12.70]; 95% CI, 719.67-745.08; P < .001). This weekly volume decrease occurred across all surgical subspecialties. During the post-COVID peak period, overall weekly surgical volumes (mean [SD] procedures per week, 624.31 [142.45]; 95% CI, 481.85-766.76) recovered to only 85.8% of pre-COVID peak volumes (P < .001). This insufficient recovery was inconsistent across subspecialties and case classes. During the post-vaccine release period, although some subspecialties experienced recovery to pre-COVID-19 volumes, others continued to experience declines. Conclusions and Relevance: This quaternary care institution effectively responded to the pressures of the COVID-19 pandemic by substantially decreasing surgical procedure volumes during the peak of the pandemic. However, overall surgical procedure volumes did not fully recover to pre-COVID-19 levels well into 2021, with inconsistent recovery rates across subspecialties and case classes. These declines suggest that delays in surgical procedures may result in potentially higher morbidity rates in the future. The differential recovery rates across subspecialties may inform institutional focus for future operational recovery.

ABSTRACT

Objective: The primary aim of the study was to translate and evaluate the impact of a Physical Activity (PA) program on the physical function of older Aboriginal Elders on Noongar Boodjar (Country). Methods: A longitudinal design framed within an Indigenous methodology. Two groups, one metropolitan and one regional, of Aboriginal Elders, aged ≥45 years, participated in the Ironbark PA program. This comprised weekly strength and balance exercises followed by yarning circles. Physical function (primary outcome) and functional ability, cardiovascular risk factors (weight, waist circumference), falls efficacy and health-related quality of life were measured at baseline 6, 12 and 24 months. Data were analyzed using generalized linear mixed effects modeling. Results: Fifty-two Elders initially enrolled and of those, n = 23 (44.2%) Elders participated regularly for 24 months. There was a 6-month gap in program delivery due to the COVID-19 pandemic. Participants made significant improvement in physical function at 12 months compared to baseline: [short physical performance battery (SPPB) at baseline, 8.85 points (95% CI 8.10, 9.61); 12 months 10.28 (95% CI 9.44, 11.13), p = 0.001: gait speed at baseline 0.81 ms-1 (95% CI 0.60, 0.93); 12 months 1.14 (95% CI 1.01, 1.27), p < 0.001]. Some sustained improvement compared to baseline was still evident at 24 months after the 6-month gap in attendance [SPPB 9.60 (8.59, 10.60) p = 0.14, gait speed 1.11 (0.95, 1.26) p < 0.001]. Cardiovascular risk factors showed a non-significant improvement at 12 and 24 months compared to baseline. All participants reported that they enjoyed the program, found it culturally appropriate and would recommend it to others. Conclusion: Older Aboriginal people showed sustained improvements in physical function after engaging in a culturally appropriate PA program. Culturally appropriate PA programs provide safety, security and choice for older Aboriginal people to engage in evidence-based PA.

ABSTRACT

Coronavirus disease 2019 (COVID-19) is associated with significant morbidity and mortality, albeit with considerable heterogeneity among affected individuals. It remains unclear which factors determine severity of illness and long-term outcomes. Emerging evidence points towards an important role of preexisting host factors, such as a deregulated inflammatory response at the time of infection. Here, we demonstrate the negative impact of clonal hematopoiesis, a prevalent clonal disorder of ageing individuals, on COVID-19-related cytokine release severity and mortality. We show that mutations in the gene coding for the methylcytosine dioxygenase TET2 promotes amplification of classical and intermediate monocyte subsets. Using single cell multiomic sequencing approaches, we identify cell-specific gene expression changes associated with the loss of TET2 and significant epigenomic deregulation affecting enhancer accessibility of a subset of transcription factors involved in monocyte differentiation. We further identify EGR1 down-regulation secondary to TET2-mediated hypermethylation, resulting in overexpression of MALAT1, a lncRNA that plays a role in hematopoietic stem cell differentiation and monocyte lineage commitment. Together, these data provide a mechanistic insight to the poor prognostic value of clonal hematopoiesis in patients infected with Sars-COV2.

ABSTRACT

Methods of communications and the nature of messaging are critically important in influencing public behavior. The COVID-19 pandemic has resulted in major disruptions to all aspects of life globally and has triggered multiple approaches of health messaging to the general public to communicate COVID-19 preventative measures. This study aimed to identify: (1) differences between age groups in the main avenues used by people to obtain COVID-19 related information;and (2) whether age and information sources were associated with correct interpretation of government messaging relating to how people understand or interpret the terms “self-isolation” and “social distancing.” An online survey was conducted in 2020. Participants were aged over 18 years and grouped into age group decades. Differences in sources of COVID-19 information were compared visually between age groups. Logistic regression was used to determine whether age and each of the various methods of communication of COVID-19 information were independently associated with correct response to the self-isolation, or the social distancing statements. There were 3,300 survey respondents 85% female;age sub-groups: 18–29 (7.4%);30–39 (10.6%);40–49 (17.6%);50–59 (22.9%);60–69 (25.9%);70–79 (13.9%);and 80+ (1.7%). People accessed public health messaging information from a wide variety of sources that changed as they aged (e.g., older people were more likely to be exposed to COVID-19 information via television news programs and less likely via social media platforms). Age was frequently associated with whether the message key terms were interpreted correctly or incorrectly, but in some cases, it promoted more correct responses whereas in others, fewer correct responses. There was no difference between being exposed to COVID-19 information via mainstream media, compared with social media, or compared with Government sources of information, in terms of whether COVID-19 messages were interpreted correctly. In order to improve future public health messaging, there is a need for multiple avenues of communication to meet the needs and preferences across and within age groups. Further investigation is warranted into the clarity of the content and method of delivery of public health messages, to ensure optimal understanding of public health messages by vulnerable populations and across the community.

ABSTRACT

The purpose of this pilot study was to explore the efficacy, safety, and tolerability of vidofludimus calcium (VC) in the treatment of primary sclerosing cholangitis (PSC). This was a single-arm open-label pilot study with a cohort of 18 patients with PSC. Study patients received VC for a period of 6 months. The study was undertaken at two sites, Mayo Clinic, Rochester, MN, and Mayo Clinic, Phoenix, AZ. The primary endpoint of the study was improvement of serum alkaline phosphatase (ALP) at the end of the study. Secondary endpoints included assessment of other liver biomarkers (bilirubin, alanine aminotransferase, and aspartate aminotransferase). Of 18 patients enrolled, 11 completed the 6 months of study treatment. Patients who completed treatment versus those who did not were similar other than a significantly higher direct bilirubin at baseline in the group that completed treatment (mean ± SD, 0.4 ± 0.3 versus 0.1 ± 0.1, p = 0.04). By intent to treat analysis, the primary outcome was met in 16.7% (3/18) of patients. By per-protocol analysis, including only patients who completed treatment, normalization of ALP occurred in 27.7% (3/11) at week 24 (95% confidence interval, 6.0% to 61.0%). VC was well tolerated with no drug-related serious adverse events. Conclusion: This proof of concept study provides support for further exploration of VC in patients with PSC.

ABSTRACT

BACKGROUND: Methacholine challenge testing (MCT) is a common bronchoprovocation technique used to assess airway hyper-responsiveness. We previously demonstrated that the addition of a viral filter to the nebulizer exhalation limb substantially reduced expelled particles during MCT. Our aim was to evaluate whether this modification affects the delivered dose of methacholine. METHODS: A mechanical ventilator was connected to a lung simulator with breathing frequency 15 breaths/min, tidal volume 500 mL, inspiratory-expiratory ratio 1:1, with a sinusoidal waveform. We compared methacholine dose delivery using the Hudson Micro Mist or AeroEclipse II BAN nebulizers powered by either a dry gas source or a compressor system. A filter placed in line between the nebulizer and test lung was weighed before and after 1 min of nebulized methacholine delivery. Mean inhaled mass was measured with and without a viral filter on the exhalation limb. Dose delivery was calculated by multiplying the mean inhaled mass by the respirable fraction (particles < 5 µm) and inhalation time. Unpaired t test was used to compare methacholine dose delivery with and without viral filter placement. RESULTS: The addition of a viral filter did not significantly affect methacholine dose delivery across all devices tested. Using a 50-psi dry gas source, dose delivered with or without a viral filter did not differ with the Hudson (422.3 µg vs 282.0 µg, P = .11) or the AeroEclipse nebulizer (563.0 µg vs 657.6 µg, P = .59). Using the compressor, dose delivered with and without a viral filter did not differ with the Hudson (974.0 µg vs 868.0 µg, P = .03) or the AeroEclipse nebulizer (818.0 µg vs 628.5 µg, P = .42). CONCLUSIONS: The addition of a viral filter to the nebulizer exhalation limb did not affect methacholine dose during bronchoprovocation testing. Routine use of a viral filter should be considered to improve pulmonary function technician safety and infection control measures during the ongoing COVID-19 pandemic.

ABSTRACT

Objective: Study aimed to identify the prevalence of falls and associated contributory factors among older Malaysians. Methods: A cross sectional study among community dwelling older adults aged 50 years and above. Self-administered questionnaires on history of falls in the previous 12 months, physical assessment and computerized and clinical measures of balance were assessed on a single occasion. Results: Forty nine (31.0%) participants fell, with 4.4% reported having multiple falls within the previous 12 months. Slips were the most prevalent cause of falls, accounting for 49% of falls. More than half (54.5%) of falls occurred in the afternoon while participants walked inside the home (32.7%), outside home (30.6%), and 36.7% were in community areas. More than half of respondents were identified as having turning instability. Step Test, turn sway, depression, physical activity level and edge contrast sensitivity were significantly worse for fallers (p < 0.05). Multiple logistic regression analysis showed that turning performance, visual acuity and back pain were significantly associated with falls risk, accounting for 72% of the variance of risk factors for falls among studied population. Conclusion: Falls are common among community dwelling older Malaysians. The findings provide information of falls and falls risk factors among community dwelling older adults in Malaysia. Future intervention studies should target locally identified falls risk factors. This study has highlighted the importance of instability during turning as an important fall risk factor.

ABSTRACT

SARS-CoV-2 primarily replicates in mucosal sites, and more information is needed about immune responses in infected tissues. Here, we used rhesus macaques to model protective primary immune responses in tissues during mild COVID-19. Viral RNA levels were highest on days 1-2 post-infection and fell precipitously thereafter. 18F-fluorodeoxyglucose (FDG)-avid lung abnormalities and interferon (IFN)-activated monocytes and macrophages in the bronchoalveolar lavage (BAL) were found on days 3-4 post-infection. Virus-specific effector CD8+ and CD4+ T cells became detectable in the BAL and lung tissue on days 7-10, after viral RNA, radiologic evidence of lung inflammation, and IFN-activated myeloid cells had substantially declined. Notably, SARS-CoV-2-specific T cells were not detectable in the nasal turbinates, salivary glands, and tonsils on day 10 post-infection. Thus, SARS-CoV-2 replication wanes in the lungs of rhesus macaques prior to T cell responses, and in the nasal and oral mucosa despite the apparent lack of antigen-specific T cells, suggesting that innate immunity efficiently restricts viral replication during mild COVID-19.

ABSTRACT

SETTING: In January 2021, the COVID-19 vaccine became available to First Nations, Métis, and Inuit (FNMI) over the age of 65 living in First Nations communities or Métis settlements in Alberta. In March, vaccine eligibility in Alberta expanded to include FNMI peoples of younger ages and in urban settings. The Métis Nation of Alberta (MNA) and other Indigenous organizations recognized that FNMI populations might be better served by tailored vaccine programs. INTERVENTION: The MNA is the government for the Métis people in Alberta. During the COVID-19 pandemic, the MNA has supported its citizens, through financial and mental wellness support, access to personal protective equipment, and messaging regarding public health orders. When vaccines became available, culturally appropriate virtual vaccine information sessions were provided. In March 2021, the MNA delivered the first Métis-led COVID-19 vaccination clinic. Unique to the clinic's success was the location, online booking process, and community presence. The clinic focused on cultural safety, including the availability of Indigenous health professionals to community members, and cultural reference points throughout the clinic. OUTCOMES: In the first MNA clinic, over 1300 people were vaccinated. Visitors shared appreciation for the culturally specific aspects of the clinic, which contributed to increased safety and comfort. IMPLICATIONS: Based on the success of the first Métis-led vaccination clinic, similar services in communities with high numbers of Métis people have been approved. This innovative practice initiative could provide a model of COVID-19 vaccine service delivery that could be used to meet the needs of Métis citizens in other jurisdictions in Canada.


RéSUMé: LIEU: En janvier 2021, le vaccin anti-COVID-19 est devenu accessible aux Premières Nations, Inuits et Métis (PNIM) de 65 ans et plus vivant dans les communautés des Premières nations ou les établissements métis de l'Alberta. En mars, l'admissibilité au vaccin en Alberta a été étendue aux personnes des PNIM plus jeunes et vivant en milieu urbain. La Nation métisse de l'Alberta (NMA) et d'autres organismes autochtones ont pensé que les populations PNIM seraient peut-être mieux servies par des programmes de vaccination adaptés. INTERVENTION: La NMA est le gouvernement des Métis en Alberta. Durant la pandémie, la NMA a appuyé ses citoyens en leur offrant des mesures d'aide financière et de bien-être mental, en leur donnant accès à de l'équipement de protection individuelle et en diffusant des messages sur les ordonnances de santé publique. Quand les vaccins sont devenus disponibles, des séances d'information virtuelles culturellement appropriées ont été offertes. En mars 2021, la NMA a monté la première clinique de vaccination contre la COVID-19 dirigée par des Métis. Le succès de cette clinique a reposé sur son emplacement, sur le processus de prise de rendez-vous et sur la présence communautaire. La clinique a mis l'accent sur la sécurisation culturelle, notamment en mettant à la disposition des résidents des professionnels de la santé autochtones et en plaçant des références culturelles à plusieurs endroits. RéSULTATS: Au cours de la première clinique de la NMA, plus de 1 300 personnes se sont fait vacciner. Les visiteurs ont dit apprécier les aspects culturellement spécifiques de la clinique, qui ont contribué à en accroître la sécurité et le confort. CONSéQUENCES: Avec le succès de la première clinique de vaccination dirigée par des Métis, des services semblables ont été approuvés dans des communautés où les Métis sont nombreux. Cette initiative novatrice pourrait être un modèle de prestation de services de vaccination contre la COVID-19 adaptés aux besoins des citoyens de la Nation métisse dans d'autres provinces et territoires du Canada.
