In August 2020, the World Health Organization reported that 89% of 105 surveyed countries reported disruption to essential health services during the coronavirus disease 2019 (COVID-19) pandemic. 1 In late June 2020, when there were 2.5 million cumulative confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in the United States, 2 40.9% of 4977 surveyed US adults reported having delayed or avoided medical care due to COVID-19 concerns. 3 Given the potential short-and long-term consequences of medical care delay or avoidance, we sought to determine whether similar care avoidance was observed in a region with low SARS-CoV-2 prevalence. As of mid-September 2020, the Australian state of Victoria reported fewer than 20,000 cumulative SARS-CoV-2 cases with a low positivity rate 4 in a population of approximately 6.7 million people. Cross-sectional Internet-based surveys were therefore administered to respondent panellists aged ≥18 years residing in Victoria by Qualtrics using quota sampling in the third Australian wave of The COVID-19 Outbreak Public Evaluation (COPE) Initiative (www.thecopeinitiative.org). To assess medical care avoidance cross-sectionally while minimizing potential confounders of varying mitigation measures or SARS-CoV-2 prevalence, surveys were administered during 15-24 September 2020, when peak COVID-19 prevention measures were in place.

Participants were asked, 'In the past month, have you delayed or avoided medical care due to concerns related to COVID-19?' Delay or avoidance was evaluated for emergency (e.g., immediate life-threatening conditions), urgent (e.g., immediate non-life-threatening conditions) and routine (e.g., annual check-ups) medical care. Urgent and emergency care avoidance were combined for analysis (urgent or emergency care) due to potential variance in perception of level of care needed, and a variable representing any care avoidance was created. Demographic and health information were collected as covariates, including sex, age, ancestry, regional versus metropolitan postcode, education attainment, employment status, unpaid caregiver status (providing unpaid care for children only, for adults only, for both age groups [multigenerational] or not an unpaid caregiver), disability status and support through the National Disabilities Insurance Scheme (NDIS) and presence of underlying conditions known to increase the risk of severe COVID-19, including: obesity (BMI > 30 kg/m 2 ), diabetes, hypertension, cardiovascular disease, chronic kidney disease, liver disease, chronic obstructive pulmonary disease and cancer.

Surveys underwent Qualtrics data-quality screening procedures, including algorithmic and keystroke analysis for click-through behaviour, duplicate responses, machine responses and inattentiveness. The investigators conducted secondary cleaning for missing sex and age, invalid postcodes and BMI below 14 or above 100 kg/m 2 . Iterative proportional fitting (raking) and weight trimming ([1/3] ≤ weight ≤ [3] ) were employed to improve sample representativeness by age and sex according to Victorian population estimates from the Australian Bureau of Statistics 2016 Census of Population and Housing.

Rao-Scott adjusted Pearson chi-square tests with a Bonferroni adjustment (10 comparisons) were used to test for differences in delay or avoidance of routine, urgent or emergency, and any medical care by demographic subgroups. Adjusted prevalence ratios (aPRs) and 95% CIs for delay or avoidance of any medical care were estimated using Poisson regressions with robust SEs among respondents who had complete data for the following variables: sex, age, ancestry, regional or metropolitan residence, education attainment, employment status and unpaid caregiver status. Additional models including these variables plus either disability status or presence of underlying medical conditions were used to estimate aPRs for these collinear variables. Statistical analyses were conducted with Python (version 3.7.8; Python Software Foundation) and R version 4.0.2 (The R Project for Statistical Computing) using the R survey package version 3.29; p < 0.05 were deemed statistically significant.

During Multivariate Poisson regression revealed that avoidance of any medical care was more common among multigenerational unpaid caregivers and unpaid caregivers for adults compared to those who were not unpaid caregivers (e.g., multigenerational, aPR = 2.42, 95% CI = 1.98-2.97, p < 0.0001); in those with multiple medical conditions compared to those without (one health condition, aPR = 1.45, 95% CI = 1.14-1.83, p = 0.0022; two or more health conditions, aPR = 2.02, 95% CI = 1.60-2.54, p < 0.0001); those with disabilities compared to those without disabilities (with NDIS support, aPR = 1.46, 95% CI = 1.21-1.75, p = 0.0001; without NDIS support, aPR = 1.44, 95% CI = 1.06-1.95, p = 0.018); females compared to males (aPR = 1.30, 95% CI = 1.09-1.55, p = 0.0036); and those with a doctoral or professional degree versus a bachelor's degree (aPR = 1.21, 95% CI = 1.00-1.47, p = 0.046).

These findings provide important insights regarding healthcare-seeking behaviour during the COVID-19 pandemic in a region with relatively low SARS-CoV-2 prevalence. Intentional medical care avoidance may have contributed to the observed 22% decrease in Victorian emergency department (ED) presentations during September 2020 compared to September 2019. 5 Individuals with multiple medical conditions associated with an increased risk of severe COVID-19 more commonly avoided or delayed urgent or emergency care, a finding also observed in the United States. 3 This is particularly concerning, as in addition to higher risk of severe COVID-19, these conditions put individuals at greater risk of other acute medical conditions for which time-critical interventions can reduce morbidity and mortality. Decreased presentations of stroke and myocardial infarction occurred during July and August 2020 in Victoria, Australia, 5 and symptom-to-doortime for patients with acute coronary syndrome requiring revascularization increased four-fold during March and April 2020, whilst overall case presentations remained unchanged. 6 These observations suggest that people delayed seeking urgent care.

Early evidence of consequences of disrupted routine care during the COVID-19 pandemic have been reported, particularly in relation to cancer screening and diagnoses. Reduced screening, referrals and presentations for lung and colorectal cancers in the UK have led to projections of 4.8% and 16.5% increased deaths, respectively, within 5 years of diagnosis. 7, 8 In Victoria, on 11 September 2020, the Premier urged Victorians to stop delaying hospital visits and health check-ups due to the pandemic, as not only had ED visits reduced, diagnoses for common cancers had reduced by approximately one-third. 9 Findings from this study suggest that strategies to reduce COVID-19-related care avoidance may be warranted, with enhanced efforts among at-risk groups.

Although quota sampling and survey weighting were employed to improve sample representatives of the Victorian population by age and sex, the sample may not be fully representative of the 2020 Victorian population. Furthermore, self-reported data may be subject to recall and response biases, and this study did not assess reasons for COVID-19 care avoidance or baseline patterns of careseeking or avoidance in this population; however, the results are consistent with trends in Victorian hospital and ED admissions data. Finally, although the survey items specified that the reason for delay or avoidance of medical care was COVID-19 concerns, respondents did not detail sources of these concerns (e.g., fear of SARS-CoV-2 infection or spreading SARS-CoV-2 to others at the healthcare facility, during transportation to or from the facilities). Future research could identify such sources of COVID-19-related concerns, and what measures may lead to their alleviation.

Given that considerable portions of adults reported having delayed or avoided medical care due to COVID-19 concerns in regions with minimal (Victoria) and substantial (United States) community transmission of SARS-CoV-2, determining the extent to which similar behaviour has continued in these regions and may be occurring in other regions is warranted. To that end, the World Health Organization has recently developed a population health surveillance tool to monitor delay or avoidance of medical care among the wider effects of the COVID-19 pandemic. 10 Proactive public health messaging and targeted services to minimize healthcare avoidance-particularly for individuals with chronic medical conditions, people with disabilities and unpaid caregivers-may be critical to avoid preventable increases in all-cause morbidity and mortality during and beyond the COVID-19 pandemic.
