Description of intervention(s) / exposure
The COVIC-HA Cohort Study aims to establish a cohort of Victorian healthcare and aged care workers across four different settings (first responders, hospitals, primary care, aged care) to comprehensively examine the impacts of the COVID-19 pandemic on healthcare and aged care workers and workplaces over time using a mixed-methods approach. Workers from different occupational groups (doctors, nurses, paramedics, allied health, personal care assistants and support staff) will be included. The key research activities of the study will be conducted in two phases:

Phase 1
All Participants will be invited to complete quantitative surveys (each six months apart) to monitor COVID-19 impacts during 2021-2022, and consent to data linkage. Each survey (at baseline and 6 months) should take approximately 15 minutes to complete. Survey data collected will include demographic, health and wellbeing data, and information about workers perceptions of their organisation’s response to the COVID-19 pandemic. Additionally, participants will be invited to complete occasional (brief) optional surveys circulated in response to acute changes in the COVID-19 environment. At the time of each survey, both existing and new participants at enrolled sites will be eligible to complete the survey (open cohort design). Data linkage will be done with the following administrative health datasets: a) Commonwealth Datasets: Medicare Benefits Schedule (MBS) and Pharmaceutical Benefits Scheme (PBS); b) Victorian Datasets: Victorian Admitted Episode Database (VAED), Victorian Emergency Minimum Dataset (VEMD), Ambulance Victoria (AV) dataset

Phase 2:
A subset of the cohort will be invited to consent to voluntary participation in qualitative interviews to explore personal experiences of the COVID-19 pandemic: A sub-sample of participants will be purposively recruited for semi-structured interviews to explore their lived experiences of COVID-19. Selection will be based on characteristics determined from quantitative data (e.g. gender, work role, socioeconomic status, exposure to COVID-19) to ensure a diverse range of perspectives is represented. Up to 90 participants will be selected to complete interviews that will be conducted in 2-3 successive rounds, dependent on the thematic saturation achieved as well as the evolving COVID-19 environment. The interview length will depend on how much each participant wants to say, but it could take about 30 minutes.

Depending on participant engagement, thematic findings and COVID-19 infection patterns, some participants may be asked to participate in a second round of qualitative interviews at 12 months.

Additionally, semi-structured one-on-one interviews will be conducted with senior management personnel from each participating site. We will recruit 2-3 senior management personnel from each participating site to explore systems in place for controlling workplace risks and policies and programs in place to prepare and support workers during the COVID-19 pandemic.

Statistical methods / analysis
Physical and psychosocial health will be assessed using standardised self-report measures of general health, quality of life, anxiety, stress, depression, burnout, professional fulfilment and resilience that are sensitive to changes with time.

Survey data will be analysed using STATA version 16 or later and SAS version 16. Descriptive statistics will be used to describe the characteristics of the sample. Primary outcomes will be summarised by the factors of interest using means (standard deviation) or frequencies (percentages) or graphical displays where appropriate. Linear mixed effects models will be used to allow comparison of continuous outcomes between groups. Comparisons between groups will be made at baseline, and changes in measures over time will be compared between groups. Regression models for baseline comparisons and comparisons of changes over time between groups will include terms for age, gender, SES decile of advantage/disadvantage (Index of relative socioeconomic advantage and disadvantage [IRSAD]), and an indicator for date of participation. Random intercepts will be included to account for the clustering of HCWs within work sites. For analysis of binary outcomes, similar random effect models will be used to estimate risk ratios and 95% confidence intervals using a logarithmic link function, or using a logistic link marginalised to obtain risk ratios if convergence problems occur. Multiple imputation using chained equations was performed to account for missing data. Data was considered missing if it arose from question-specific non-response through a response of “Not applicable” or similar, or from time-specific non-response from a respondent who completed at least one but not all surveys.

Transcripts from qualitative interviews will be analysed thematically by qualitative researchers using NVivo according an established method described by Braun and Clarke. Researchers will work together to establish a hierarchy of themes, constructed during repeated readings of all transcripts. The final set of themes will then be used to search all transcripts.
