Webinar Recording: Scoping Population Health in Impact Assessment (ScopHIA)

Identifying Best Practices for Scoping Major Natural Resource and Large-Scale Infrastructure Projects under Canada's Impact Assessment Act

Canada’s Impact Assessment Act provides new opportunities for public health practitioners, researchers, and policy makers working to improve population health equity for many marginalized and vulnerable populations. Impact assessments are federal review processes conducted for major natural resource developments and large infrastructure projects such as mines, oil and gas fields, or pipelines. Typically located in more rural and remote regions of the country, major projects can provide income, employment, and other benefits for nearby communities. At the same time, major projects may pose risks to community health and wellbeing, including exposure to pollution and loss of ecosystem services, stress on community infrastructure and food and water security, and interfering with land-based cultural practices.

Webinar Recording - Psychosocial Impacts of the COVID-19 pandemic: A frame of reference from lessons learned through disasters in Canada

Topics: COVID-19

There is no doubt that mental health challenges posed by disasters will increase due to climate, demographic and social changes. This presentation details findings from Canadian-led studies on the psychosocial impacts resulting from communities who experienced large-scale disasters in Canada. Such traumatic events include the COVID-19 pandemic, the 2019 Quebec spring floods, the 2016 Fort McMurray wildfires, and the 2013 Lac-Mégantic train derailment. There are links between observed psychosocial impacts and recovery during these recent disasters, with learnings that could be applied to the COVID-19 pandemic that could promote individual and community resilience following disasters. This session will be relevant to environmental and public health professionals in health prevention and health promotion roles.

Webinar Recording - Surface Cleaning and Disinfection in the Context of the COVID-19 Pandemic

Topics: COVID-19

Fomite transmission is acknowledged as one of the potential transmission routes of SARS-CoV-2. Thus, appropriate cleaning and disinfection of surfaces is one of the non-pharmaceutical control measures recommended by public health. However, while adequate cleaning and disinfection may be important to sever this chain of transmission of COVID-19, excessive cleaning and disinfection has led to an increase in accidental exposure to harmful cleaning and disinfection by-products due to heightened concerns about SARS-CoV-2 persisting on food, food packaging, and environmental surfaces. Improving public health practitioners’ understanding of appropriate cleaning and disinfection practices and the risks of misuse and overuse of disinfectant products would help to guide public health recommendations in public and private settings.

Webinar Recording: COVID-19 management in personal services settings: Lessons learned from a nail salon outbreak

Topics: COVID-19

Between June 20 and July 3, 2020 a COVID-19 outbreak associated with a personal service setting (PSS) was detected in the Kingston, Ontario and managed by the local public health unit (KFL&APH).

A mixed-methods analysis was conducted to review KFL&APH’s response to the outbreak. A social network analysis was conducted to determine the extent of the outbreak and route of acquisition of cases. Epidemic curves were created and analysed. Attack rates were calculated, and testing data and overall testing strategy were reviewed.

The outbreak consisted of 37 cases with 14 through direct PSS exposure. 23 cases were from subsequent generations, and a superspreading event led to 14 of those cases. The average age of cases was 38.6 years and 65% were female. One case required hospitalization. Over 10 000 tests were conducted using a multimodal approach, including fixed assessment centres, drive-through testing and targeted testing at outbreak sites. PCR lab results…

Conducting a Literature Search and Semi-Systematic Review: The NCCEH Approach

Evidence-informed decision-making seeks to incorporate both scientific or academic knowledge, as well as the practical knowledge of public health professionals. However, the use of scientific evidence is hindered by a number of factors, particularly the lack of an easy-to-use protocol to search, appraise and synthesize academic sources in a timely manner. In this document, we provide an overview of semi-systematic literature reviews as a way to incorporate scientific evidence into EIDM, and we provide a step-by-step protocol encompassing literature search, critical appraisal, and synthesizing new knowledge. The intent of this document is to both assist public health practitioners who wish to conduct their own reviews, as well as provide insight in to the literature review process at NCCEH.

Indoor environmental quality of sustainable building designs and occupant health

The NCCEH Environmental Health Seminar Series provides an opportunity for learning and knowledge exchange on a variety of environmental health topics. The seminars can be attended in-person or online.

Presenter: Dr. Karen Bartlett, School of Population and Public Health, University of British Columbia

Occupants of buildings depend on what we term “good” Indoor Environmental Quality (IEQ). The actual definition of IEQ is somewhat elusive, as it is the absence of problems in the indoor environment which could detract from the health and productivity of occupants. Buildings need to be designed and built with the occupant in mind, and as we rapidly progress into sustainable building designs, we also need to make sure that buildings can accommodate the changing environments of our cities and climate. We will explore some of the facets of the occupant/building interface in these changing environments.
