COVID-19 pandemic responses of Canada and United States in first 6 months: A comparative analysis

Exploring policy processes against microbial threats in Iran: a qualitative policy analysis

OBJECTIVES

Microbial threats pose a growing concern worldwide. This paper reports the analysis of Iran's policy process against microbial threats.

DESIGN

This is a qualitative study.

PARTICIPANTS

We interviewed 16 purposefully identified key informants selected through snowball sampling.

SETTING

Through the lens of stages heuristic framework, we analysed the interviews by using thematic content analysis. We used MAXQDA V.2020 software for data analysis, identified key themes and subthemes and discussed our findings to validate the results.

RESULTS

We extracted four main categories in accordance with the stages heuristic domains. Through content analysis of the agenda-setting process, we identified three main themes: magnitude of the problem, actors' power and priorities. Participants highlighted the significant impact of microbial threats, the influence of powerful stakeholders and the underprioritisation of infectious diseases based on perceived urgency and resources. In the process of policy formulation, we explored three main themes, related to governance, coherence and integration of policies and barriers to effective policy formulation. Governance issues included transparency, engagement with stakeholders, conflict of interest and use of evidence, while coherence and integration of policies focused on insufficient coherence and integration of plans as well as temporary and defensive policymaking. Barriers to effective policy formulation encompassed delay in policymaking, policy gap in response to public needs, weakness in policy feasibility, risk assessment and management. For policy implementation, we extracted governance and coordination, and health system capacity. Effective implementation of policies was hindered by fragmented governance, inadequate communication and accountability and systemic barriers, while health system capacity was limited in terms of infrastructure and human resources. Finally, content analysis of monitoring and evaluation (M&E) resulted in identification of two main themes: discrepancies in M&E and barriers to effective M&E. The discrepancies in M&E varied, with some programmes having regular evaluations and others lacking compliance with international standards. Barriers to effective M&E included inadequate data access, limited information-sharing and inefficiencies in the M&E system.

CONCLUSIONS

Iran needs to prioritise infectious diseases, invest in preventive measures, improve governance and coordination, strengthen health system capacity, enhance M&E and so on, to combat microbial threats effectively. Learning from successful experiences of other countries can help Iran develop more effective strategies to address microbial threats and strengthen global public health in the country.

Updated Surveillance Metrics and History of the COVID-19 Pandemic (2020-2023) in Canada: Longitudinal Trend Analysis

BACKGROUND

This study provides an update on the status of the COVID-19 pandemic in Canada, building upon our initial analysis conducted in 2020 by incorporating an additional 2 years of data.

OBJECTIVE

This study aims to (1) summarize the status of the pandemic in Canada when the World Health Organization (WHO) declared the end of the public health emergency for the COVID-19 pandemic on May 5, 2023; (2) use dynamic and genomic surveillance methods to describe the history of the pandemic in Canada and situate the window of the WHO declaration within the broader history; and (3) provide historical context for the course of the pandemic in Canada.

METHODS

This longitudinal study analyzed trends in traditional surveillance data and dynamic panel estimates for COVID-19 transmissions and deaths in Canada from June 2020 to May 2023. We also used sequenced SARS-CoV-2 variants from the Global Initiative on Sharing All Influenza Data (GISAID) to identify the appearance and duration of variants of concern. For these sequences, we used Nextclade nomenclature to collect clade designations and Pangolin nomenclature for lineage designations of SARS-CoV-2. We used 1-sided t tests of dynamic panel regression coefficients to measure the persistence of COVID-19 transmissions around the WHO declaration. Finally, we conducted a 1-sided t test for whether provincial and territorial weekly speed was greater than an outbreak threshold of 10. We ran the test iteratively with 6 months of data across the sample period.

RESULTS

Canada's speed remained below the outbreak threshold for 8 months by the time of the WHO declaration ending the COVID-19 emergency of international concern. Acceleration and jerk were also low and stable. While the 1-day persistence coefficient remained statistically significant and positive (1.074; P<.001), the 7-day coefficient was negative and small in magnitude (-0.080; P=.02). Furthermore, shift parameters for either of the 2 most recent weeks around May 5, 2023, were negligible (0.003 and 0.018, respectively, with P values of .75 and .31), meaning the clustering effect of new COVID-19 cases had remained stable in the 2 weeks around the WHO declaration. From December 2021 onward, Omicron was the predominant variant of concern in sequenced viral samples. The rolling 1-sided t test of speed equal to 10 became entirely insignificant from mid-October 2022 onward.

CONCLUSIONS

While COVID-19 continues to circulate in Canada, the rate of transmission remained well below the threshold of an outbreak for 8 months ahead of the WHO declaration. Both standard and enhanced surveillance metrics confirm that the pandemic had largely ended in Canada by the time of the WHO declaration. These results can inform future public health interventions and strategies in Canada, as well as contribute to the global understanding of the trajectory of the COVID-19 pandemic.

Evaluating the before operational stress program: comparing in-person and virtual delivery

Introduction

Public safety personnel (PSP) are at increased risk for posttraumatic stress injuries (PTSI). Before Operational Stress (BOS) is a mental health program for PSP with preliminary support mitigating PTSI. The current study compared the effectiveness of delivering BOS in-person by a registered clinician (i.e., Intensive) to virtually delivery by a trained clinician (i.e., Classroom).

Methods

Canadian PSP completed the Intensive (n = 118; 61.9% male) or Classroom (n = 149; 50.3% male) program, with self-report surveys at pre-, post-, 1 month, and 4 months follow-ups.

Results

Multilevel modelling evidenced comparable reductions in anxiety (p < 0.05, ES = 0.21) and emotional regulation difficulties (ps < 0.05, ESs = 0.20, 0.25) over time with no significant difference between modalities. Participants discussed benefits of the delivery modality they received.

Discussion

The results support virtual delivery of the BOS program (Classroom) as an accessible mental health training option for PSP, producing effects comparable to in-person delivery by clinicians.

Operational status of mental health, substance use, and problem gambling services: A system-level snapshot two years into the COVID-19 pandemic

BACKGROUND

The aim of this paper is to provide a system-level snapshot of the operational status of mental health, substance use, and problem gambling services 2 years into the pandemic in Ontario, Canada, with a specific focus on services that target individuals experiencing vulnerable circumstances (e.g., homelessness and legal issues).

METHODS

We examined data from 6038 publicly funded community services that provide mental health, substance use, and problem gambling services in Ontario. We used descriptive statistics to describe counts and percentages by service type and specialisation of service delivery. We generated cross-tabulations to analyse the relationship between the service status and service type for each target population group.

RESULTS

As of March 2022, 38.4% (n = 2321) of services were fully operational, including 36.0% (n = 1492) of mental health, 44.1% (n = 1037) of substance use, and 23.4% (n = 78) of problem gambling services. These service disruptions were also apparent among services tailored to sexual/gender identity (women/girls, men/boys, 2SLGBTQQIA + individuals), individuals with legal issues, with acquired brain injury, and those experiencing homelessness.

CONCLUSION

Accessible community-based mental health, substance use and problem gambling services are critical supports, particularly for communities that have historically contended with higher needs and greater barriers to care relative to the general population. We discuss the public health implications of the findings for the ongoing pandemic response and future emergency preparedness planning for community-based mental health, substance use and problem gambling services.

Equity Lens on Canada's COVID-19 Response: Review of the Literature

BACKGROUND

A growing literature has documented how the secondary effects of the COVID-19 pandemic have compounded socioeconomic vulnerabilities already present in society, particularly across social categories such as gender, race, class, and socioeconomic status. Such effects demonstrate how pandemic response policies act as structural determinants of health to influence not only direct health outcomes but also intermediary outcomes, such as access to education or income.

METHODS

This review aims to scope research that analyzes pandemic response policies in Canada from an equity perspective, to identify common themes, recommendations, and gaps.

RESULTS

Fourteen studies were thematically analyzed, the majority being qualitative policy document analysis, applying critical frameworks and focused on effects on select priority populations. Analysis of economic and labour policies indicates a lack of consideration for the specific needs of priority populations, and those engaged in precarious, informal, and essential labour. Analysis of social policies illustrate the wide-ranging effects of school and service closures, particularly on women and children. Furthermore, these policies lacked consideration of populations marginalized during the pandemic, include older adults and their caregivers, as well as lack of consideration of the diversity of Indigenous communities. Recommendations proposed in this review call for developing policy responses that address persistent social and economic inequities, pandemic response policies tailored to the needs of priority populations and more meaningful consultation during policy development.

CONCLUSION

The limited number of studies suggests there is still much scope for research recognizing policies as structural determinants of health inequities, including research which takes an intersectional approach.

Inferring COVID-19 testing and vaccination behavior from New Jersey testing data

Characterizing the relationship between disease testing behaviors and infectious disease dynamics is of great importance for public health. Tests for both current and past infection can influence disease-related behaviors at the individual level, while population-level knowledge of an epidemic's course may feed back to affect one's likelihood of taking a test. The COVID-19 pandemic has generated testing data on an unprecedented scale for tests detecting both current infection (PCR, antigen) and past infection (serology); this opens the way to characterizing the complex relationship between testing behavior and infection dynamics. Leveraging a rich database of individualized COVID-19 testing histories in New Jersey, we analyze the behavioral relationships between PCR and serology tests, infection, and vaccination. We quantify interactions between individuals' test-taking tendencies and their past testing and infection histories, finding that PCR tests were disproportionately taken by people currently infected, and serology tests were disproportionately taken by people with past infection or vaccination. The effects of previous positive test results on testing behavior are less consistent, as individuals with past PCR positives were more likely to take subsequent PCR and serology tests at some periods of the epidemic time course and less likely at others. Lastly, we fit a model to the titer values collected from serology tests to infer vaccination trends, finding a marked decrease in vaccination rates among individuals who had previously received a positive PCR test. These results exemplify the utility of individualized testing histories in uncovering hidden behavioral variables affecting testing and vaccination.

COVID-19 diagnostic testing and vaccinations among First Nations in Manitoba: A nations-based retrospective cohort study using linked administrative data, 2020-2021

BACKGROUND

Differential access to healthcare has contributed to a higher burden of illness and mortality among First Nations compared to other people in Canada. Throughout the Coronavirus Disease 2019 (COVID-19) pandemic, First Nations organizations in Manitoba partnered with public health and Manitoba government officials to ensure First Nations had early, equitable and culturally safe access to COVID-19 diagnostic testing and vaccination. In this study, we examined whether prioritizing First Nations for vaccination was associated with faster uptake of COVID-19 vaccines among First Nations versus All Other Manitobans (AOM).

METHODS AND FINDINGS

In this retrospective cohort study, we used linked, whole-population administrative data from the Manitoba healthcare system (February 2020 to December 2021) to determine rates of COVID-19 diagnostic testing, infection, and vaccination, and used adjusted restricted mean survival time (RMST) models to test whether First Nations received their first and second vaccine doses more quickly than other Manitobans. The cohort comprised 114,816 First Nations (50.6% female) and 1,262,760 AOM (50.1% female). First Nations were younger (72.3% were age 0 to 39 years) compared to AOM (51% were age 0 to 39 years) and were overrepresented in the lowest 2 income quintiles (81.6% versus 35.6% for AOM). The 2 groups had a similar burden of comorbidities (65.8% of First Nations had none and 6.3% had 3 or more; 65.9% of AOM had none and 6.0% had 3 or more) and existing mental disorders (36.9% of First Nations were diagnosed with a mood/anxiety disorder, psychosis, personality disorder, or substance use disorder versus 35.2% of AOM). First Nations had crude infection rates of up to 17.20 (95% CI 17.15 to 17.24) COVID-19 infections/1,000 person-months compared with up to 6.24 (95% CI 6.16 to 6.32) infections/1,000 person-months among AOM. First Nations had crude diagnostic testing rates of up to 103.19 (95% CI 103.06 to 103.32) diagnostic COVID-19 tests/1,000 person-months compared with up to 61.52 (95% CI 61.47 to 61.57) tests/1,000 person-months among AOM. Prioritizing First Nations to receive vaccines was associated with faster vaccine uptake among First Nations versus other Manitobans. After adjusting for age, sex, income, region of residence, mental health conditions, and comorbidities, we found that First Nations residents received their first vaccine dose an average of 15.5 (95% CI 14.9 to 16.0) days sooner and their second dose 13.9 (95% CI 13.3 to 14.5) days sooner than other Manitobans in the same age group. The study was limited by the discontinuation of population-based COVID-19 testing and data collection in December 2021. As well, it would have been valuable to have contextual data on potential barriers to COVID-19 testing or vaccination, including, for example, information on social and structural barriers faced by Indigenous and other racialized people, or the distrust Indigenous people may have in governments due to historical harms.

CONCLUSION

In this study, we observed that the partnered COVID-19 response between First Nations and the Manitoba government, which oversaw creation and enactment of policies prioritizing First Nations for vaccines, was associated with vaccine acceptance and quick uptake among First Nations. This approach may serve as a useful framework for future public health efforts in Manitoba and other jurisdictions across Canada.

The Intersections of COVID-19 Global Health Governance and Population Health Priorities: Equity-Related Lessons Learned From Canada and Selected G20 Countries

Background: COVID-19-related global health governance (GHG) processes and public health measures taken influenced population health priorities worldwide. We investigated the intersection between COVID-19-related GHG and how it redefined population health priorities in Canada and other G20 countries. We analysed a Canada-related multilevel qualitative study and a scoping review of selected G20 countries. Findings show the importance of linking equity considerations to funding and accountability when responding to COVID-19. Nationalism and limited coordination among governance actors contributed to fragmented COVID-19 public health responses. COVID-19-related consequences were not systematically negative, but when they were, they affected more population groups living and working in conditions of vulnerability and marginalisation. Policy options and recommendations: Six policy options are proposed addressing upstream determinants of health, such as providing sufficient funding for equitable and accountable global and public health outcomes and implementing gender-focused policies to reduce COVID-19 response-related inequities and negative consequences downstream. Specific programmatic (e.g., assessing the needs of the community early) and research recommendations are also suggested to redress identified gaps. Conclusion: Despite the consequences of the COVID-19 pandemic, programmatic and research opportunities along with concrete policy options must be mobilised and implemented without further delay. We collectively share the duty to act upon global health justice.

"I haven't really gone through things like this": Young long-term care workers' experiences of working during the COVID-19 pandemic

BACKGROUND

Long-term care (LTC) facilities were hard hit by the COVID-19 pandemic in Canada. Using life course theory concepts, we looked for conditions that led to worker moral distress -i.e. pain or anguish over not being able to take right action - and how life stage may influence experiences.

OBJECTIVE

To illuminate the experiences of adults under the age of 30 who stepped into, and/or persevered in, working in LTC during the pandemic, recognizing that this emerging workforce represents the future of LTC in Canada.

METHODS

This secondary analysis uses interview data from a sub-sample of 16 young workers between 18 and 29 years of age who had been working in Canadian LTC facilities for between 8 months and 7 years.

RESULTS

Young workers expressed feeling guilt about mourning the loss of socially significant milestones as these milestones paled by comparison to the loss of life and consequences of resident isolation they witnessed at work. To manage feelings of moral distress, young workers attempted to maintain high standards of care for LTC residents and engaged in self-care activities. For some workers, this was insufficient and leaving the field of LTC was their strategy to respond to their mental health needs.

CONCLUSION

The life stage of young LTC workers influenced their experiences of working during the COVID-19 pandemic. Interventions are needed to support young workers' wellbeing and job retention.

COVID-19-related global health governance and population health priorities for health equity in G20 countries: a scoping review

Since the declaration of the COVID-19 pandemic, the promotion of health equity including the health of various population sub-groups has been compromised, human rights jeopardised, and social inequities further exacerbated. Citizens worldwide, including in the Group of 20 (G20) countries, were affected by both global health governance (GHG) processes and decisions and public health measures taken by governments to respond to COVID-19. While it is critical to swiftly respond to COVID-19, little is known about how and to what extent the GHG is affecting population health priorities for health equity in global economies such as the G20 countries. This scoping review synthesised and identified knowledge gaps on how the COVID-19-related GHG is affecting population health priorities for policy, programme, and research in G20 countries. We followed the five-stage scoping review methodology promoted by Arksey and O'Malley and the PRISMA Extension for Scoping Reviews guidelines. We searched four bibliographic databases for references conducted in G20 countries and regions and published in English and French, between January 2020 and April 2023. Out of 4,625 references and after two phases of screening, 14 studies met the inclusion criteria. G20 countries included in the review were Australia, Brazil, Canada, China, France, India, Italy, Japan, Russia, South Africa, the United Kingdom, the United States of America, and the European Union. We found insufficient collaboration and coordination and misalignment among governance actors at multiple levels. In most cases, equity considerations were not prioritised while unequal consequences of COVID-19 public health measures on population groups were widely reported. COVID-19-related population health priorities mainly focused on upstream and midstream determinants of health. Our scoping review showed the stark inequities of COVID-19 public health outcomes, coupled with a prevalent lack of coherent collaboration and coordination among governance actors. Moreover, governance as an object of empirical study is still emerging when examining its intersection with global health and population health policy, programme, and research. An urgent shift is required to effectively act upon structural health determinants that include transformative and comprehensive policies for prevention, equity, resilience, and sustainable health.

Dynamic Patterns and Modeling of Early COVID-19 Transmission by Dynamic Mode Decomposition

INTRODUCTION

Understanding the transmission patterns and dynamics of COVID-19 is critical to effective monitoring, intervention, and control for future pandemics. The aim of this study was to investigate the spatial and temporal characteristics of COVID-19 transmission during the early stage of the outbreak in the US, with the goal of informing future responses to similar outbreaks.

METHODS

We used dynamic mode decomposition (DMD) and national data on COVID-19 cases (April 6, 2020-October 9, 2020) to model the spread of COVID-19 in the US as a dynamic system. DMD can decompose the complex evolution of disease cases into linear combinations of simple spatial patterns or structures (modes) with time-dependent mode amplitudes (coefficients). The modes reveal the hidden dynamic behaviors of the data. We identified geographic patterns of COVID-19 spread and quantified time-dependent changes in COVID-19 cases during the study period.

RESULTS

The magnitude analysis from the dominant mode in DMD showed that California, Louisiana, Kansas, Georgia, and Texas had higher numbers of COVID-19 cases than other areas during the study period. States such as Arizona, Florida, Georgia, Massachusetts, New York, and Texas showed simultaneous increases in the number of COVID-19 cases, consistent with data from the Centers for Disease Control and Prevention.

CONCLUSION

Results from DMD analysis indicate that certain areas in the US shared similar trends and similar spatiotemporal transmission patterns of COVID-19. These results provide valuable insights into the spread of COVID-19 and can inform policy makers and public health authorities in designing and implementing mitigation interventions.

Similarities in COVID-19 Mortality Between Canadian Provinces and American States Before Vaccines Were Available

Canada and the USA are often compared for their markedly different approaches to health care despite cultural similarities and sharing the world's longest international boundary. The period between the onset of the COVID-19 pandemic in January 2020 and the availability of a vaccine in December 2020 offers an ideal opportunity to compare subnational Canadian and American pandemic mortality. Preventing the spread of COVID-19 was through compliance with health orders and best practices; treatment was only available to those admitted to hospitals and whose lives were at risk. Using publicly available data from the Johns Hopkins University 2019 Novel Coronavirus Visual Dashboard, we seek to uncover if there were any similarities in Canadian provinces' and American states' monthly COVID-19 mortality per 100,000 people, building on a broader scientific push towards understanding the successes and failures of different health systems in the pandemic. The similar province and state cumulative COVID-19 mortality rate trajectories identified in our analyses do not amount to intuitive comparative jurisdictions which suggests the importance of identifying localized pandemic responses.

Impact of the COVID-19 Pandemic on Black Communities in Canada

The COVID-19 pandemic has resulted in differential impacts on the Black communities in Canada and has unmasked existing race-related health inequities. The purpose of this study was to illuminate the impacts of the COVID-19 pandemic on Black people in Canada. Historically, social inequalities have determined the impacts of pandemics on the population, and in the case of the COVID-19 pandemic, disproportionate infections and mortalities have become evident among racialized communities in Canada. This qualitative descriptive study utilized an intersectionality framework. We invited Black stakeholders across Canada to participate in semi-structured interviews to deepen our knowledge of the impacts of the COVID-19 pandemic on Black communities in Canada. A total of 30 interviews were recorded, transcribed verbatim, and analyzed using content analysis. Our findings fell into three categories: (1) increased vulnerability to COVID-19 disease, (2) mental impacts, and (3) addressing impacts of the COVID-19 pandemic. The findings show the underlying systemic inequities in Canada and systemic racism exacerbated health inequities among the Black communities and undermined interventions by public health agencies to curb the spread of COVID-19 and associated impacts on Black and other racialized communities. The paper concludes by identifying critical areas for future intervention in policy and practice.

Occupational (Therapy's) Possibilities: A Queer Reflection on the Tangled Threads of Oppression and Our Collective Liberation

This presentation stems from the work of occupational therapy and science scholars who have critically described how systems of dominance perpetuate health inequities and limit the occupational possibilities of those we aim to support. Liberation is discussed as a communal process and outcome of untangling, undoing, and reconfiguring systems of dominance that negatively impact health and limit the occupational possibilities of individuals, groups, and communities. In critically reflecting on my personal, professional, and ongoing journey toward liberation as a gay, white, able-bodied, man, I draw parallels between the systemic and intersecting oppressive forces that limit the occupational possibilities of historically marginalized groups and the need for our profession to consider its own liberation. Informed by queer theory, I question the binary discourses that separate the "Us" from the "Them," illustrating how our struggles to transform practice based on anti-oppressive principles and the liberation of our full potential as occupational therapists must be tied to the liberation of the communities we aim to support. Drawing on lessons from liberation movements, I argue for the necessity of a representative and compassionate professional community to support collective action and to position the celebration of communal achievements as resistance and acts of gratitude.

Canadian critical care nurses experiences on the front lines of the COVID-19 pandemic: a qualitative descriptive study

BACKGROUND

Recent pandemics have provided important lessons to inform planning for public health emergencies. Despite these lessons, gaps in implementation during the COVID-19 pandemic are evident. Additionally, research to inform interventions to support the needs of front-line nurses during a prolonged pandemic are lacking. We aimed to gain an understanding of critical care nurses' perspectives of the ongoing pandemic, including their opinions of their organization and governments response to the pandemic, to inform interventions to improve the response to the current and future pandemics.

METHODS

This sub-study is part of a cross-sectional online survey distributed to Canadian critical care nurses at two time points during the pandemic (March-May 2020; April-May 2021). We employed a qualitative descriptive design comprised of three open-ended questions to provide an opportunity for participants to share perspectives not specifically addressed in the main survey. Responses were analyzed using conventional content analysis.

RESULTS

One hundred nine of the 168 (64.9%) participants in the second survey responded to the open-ended questions. While perspectives about effectiveness of both their organization's and the government's responses to the pandemic were mixed, most noted that inconsistent and unclear communication made it difficult to trust the information provided. Several participants who had worked during previous pandemics noted that their organization's COVID-19 response failed to incorporate lessons from these past experiences. Many respondents reported high levels of burnout and moral distress that negatively affected both their professional and personal lives. Despite these experiences, several respondents noted that support from co-workers had helped them to cope with the stress and challenges.

CONCLUSION

One year into the pandemic, critical care nurses' lived experiences continue to reflect previously identified challenges and opportunities for improvement in pandemic preparedness and response. These findings suggest that lessons from the current and prior pandemics have been inadequately considered in the COVID-19 response. Incorporation of these perspectives into interventions to improve the health system response, and support the needs of critical care nurses is essential to fostering a resilient health workforce. Research to understand the experience of other front-line workers and to learn from more and less successful interventions, and leaders, is needed.

COVID-19 pandemic responses of Canada and United States in first 6 months: A comparative analysis

INTRODUCTION

Canada and the United States have distinct health care and social policies, and it is important to see how they had been responding to the ongoing COVID-19 pandemic.

METHODS

The study period was limited to the first 6 months of the pandemic and aimed to explore the responses by public health authorities, media, general population, and law makers during the initial phase of pandemic.

RESULTS

Social disparity, underfunded pandemic preparation, and the initial failure to act appropriately have resulted in the rapid spread of infection in both countries. In the United States, prevailing social inequalities and racism, inaccessible health care, higher rates of preexisting medical conditions and disputed political leadership have further deteriorated the situation and enhanced public suffering, particularly for the black and Indigenous communities. In Canada, its poorly regulated services of long-term care facilities, initial restriction of testing and lack of access to epidemiological data have helped spread the infection and increased casualties in vulnerable populations.

CONCLUSION

Analysis of the pandemic responses of the United States and Canada has revealed how existing social disparity, underfunded pandemic preparation, and the initial failure to act appropriately have resulted in the rapid spread of infection.
