The Alberta’s Tomorrow Project (ATP) prospective cohort study was established in 2000 to investigate the causes of cancer and chronic disease. The cohort consists of almost 55 000 participants aged 35–69 years at the time of recruitment. From 2020 to 2022, ATP conducted a longitudinal substudy, the COVID-19 Antibody Testing (CAT) study, nested in this existing cohort, to understand the spread and impact of the SARS-CoV-2. In this cohort profile, we describe the CAT study design, recruitment and initial findings.

In this prospective cohort substudy, ~4000 participants completed online surveys and provided blood samples at a study centre every 4 months for 1 year, across four cities in Alberta, Canada. The study was launched on a rolling basis beginning in September 2020 and data collection was completed in May 2022. The surveys collected information on health and lifestyle factors, COVID-19 (testing, symptoms, vaccination, public health recommendations) and impacts of the pandemic (including economic, health services, mental health). Blood samples were tested for antinucleocapsid and antispike protein SARS-CoV-2 antibodies.

A total of 4102 participants consented and attended a study centre at baseline, and almost 90% of these completed the study. Overall, participants were aged 61±10 years, 60% female, 12% came from rural areas, 45% had at least a bachelor’s degree, 24% reported a household income 4 weeks). By the end of the study, 96% of participants had received at least one COVID-19 vaccine dose. Through investigating other outcomes, it was observed that participants under 50 years of age were more likely to be assessed to have mild or moderate-to-severe anxiety and depressive symptoms compared with older participants. In addition, approximately 15% of participants reported a moderate to major impact on their ability to meet financial obligations.

Serology results, together with health, lifestyle and sociodemographic data, and the continued follow-up of these participants as part of the broader ATP cohort study (planned through 2065), will provide opportunities to investigate the long-term sequelae of COVID-19 infection as well as the broader impacts of the pandemic on physical, mental and emotional health. Data are available to researchers on request through the ATP access process.

The COVID-19 pandemic has made long-standing nursing workforce challenges apparent on an international scale. Decision-makers must develop multi-pronged approaches to foster the development and maintenance of a strong nursing workforce to support health systems. These approaches require attendance to recruitment and retention initiatives that show promise for stabilising the nursing workforce now and into the future.

Searches were conducted across MEDLINE, Embase, CINAHL and Scopus from January 2014 up to 11 March 2024. This rapid umbrella review protocol is guided by the Joanna Briggs Institute scoping review methodology and adheres to Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines. The research question guiding this review is: what structures have healthcare systems put in place to stabilise, support and sustain the nursing workforce? This review will include existing reviews of nursing workforce initiatives with outcomes that impact nursing recruitment and retention. Results will support local health transformation including the development of a jurisdictional nursing workforce stabilisation strategy. Findings from this review will be relevant for the design, refinement and implementation of nursing workforce sustainability strategies in countries around the globe and may apply to strategies for other healthcare workers.

Institutional research ethics board exemption was received. The research team is supported by an advisory group that includes provider and patient partners. The results from this study will inform the Nursing Workforce Strategy for the province of Nova Scotia as part of a larger Canadian Institutes of Health Research-funded project. They will also inform broader planning and strategy in Canada through integration with other evidence-generation activities such as comparative policy analyses and workforce planning exercises. Finally, the results will be published in a peer-reviewed journal.
