During the first and second waves of the pandemic, the number of emergency department visits dropped as COVID-19 cases rose in the community. Visits then rebounded toward pre-pandemic levels during Wave 3. The biggest drop in emergency department visits occurred during Wave 1, with almost 25,000 fewer visits — or about half the usual number — on 1 day in mid-April 2020. This was likely due to the way people interpreted public health restrictions and their fear of contracting COVID-19 while in hospital. 

Note: For this analysis, the term “wave” refers to significant surges of community cases of COVID-19 infections in Canada overall, although we recognize that the timing and size of the waves may vary by jurisdiction.

By summer 2020, as COVID-19 cases in the community decreased and public health restrictions eased, emergency department visits rebounded but remained lower than is typical for that time of year (88% of August 2019 volumes). At their lowest point during the second wave, emergency department visits dropped by almost 15,000 on 1 day (in December 2020). By June 2021, visits were about 9% lower on average than pre-pandemic levels (compared with June 2019).

Compared with 2019, emergency department (ED) visits dropped sharply by about 50% in April 2020 as the first wave of the COVID-19 pandemic took hold in Canada. As the number of COVID-19 community cases slowly declined in late spring and throughout the summer, ED visits recovered to 88% of pre-pandemic levels by August 2020. The second wave led to another drop in ED visits at the end of December, to 64% of the previous year’s volume. Starting in January 2021, ED visits began trending steadily upward, with a small decrease in April 2021 coinciding with the peak of the third wave. By the end of June 2021, ED visits had reached 91% of pre-pandemic levels.

Between March 2020 and June 2021, emergency department visits (for all urgency levels combined) were 22% below pre-pandemic levels. Less urgent and non-urgent visits decreased the most, by about 28%. With fewer people coming in to seek care, people waited less time to see a physician.

It is possible that some people may have found alternatives to emergency department care (e.g., family physicians, virtual care providers). Others may not have sought care at all.

Children and youth had the largest decrease in emergency department visits. Visits for children age 0 to 4 decreased by an average of about 50% per month compared with the pre-pandemic period, and visits for children and youth age 5 to 19 decreased by an average of 38% per month.

In addition to children and youth (or their caregivers) changing the way they accessed health care, other public health measures — such as school closures, cancellations of sports activities and stay-at-home orders — may have had an impact on emergency department visits. For example, visits for accidental falls in children age 0 to 19 declined by 27% during the pandemic period, and alcohol-related harms in youth age 10 to 19 were down 36%. Illnesses typically associated with the school environment, such as colds and influenza, also declined. A similar drop was seen in family physician visits for people age 0 to 17.

We are at a point in the year where respiratory viruses start becoming common in young children. The public health measures that helped prevent the spread of COVID-19 last year also helped reduce or prevent the spread of other respiratory illnesses. This is clear with CIHI’s data, which shows a dramatic decrease in visits to emergency departments for the youngest age group. Now that many of the measures have been relaxed across the country, combined with the evidence that Canada basically didn’t have a flu or RSV (respiratory syncytial virus) season last year, we expect to see a spike in the number of emergency department visits for these illnesses, as has been seen in other countries.— Dr. Jeremy Friedman, Associate Paediatrician-in-Chief, Hospital for Sick Children

In a typical year, respiratory conditions are the second most common reason for an urgent visit to the emergency department. Consistent with the experience in other countries,Reference1 public health measures such as physical distancing and wearing masks reduced community transmission of many seasonal respiratory viruses in Canada. This contributed to fewer emergency department visits for conditions such as bronchiolitis (in young children), influenza, pneumonia, asthma and chronic obstructive pulmonary disease (COPD). 

During the pandemic period, emergency department visits for respiratory conditions — excluding confirmed cases of COVID-19 — dropped by 45% from pre-pandemic levels to an average of about 42,000 visits per month. To explore data for COVID-19 patients, please see CIHI’s COVID-19 hospitalization and emergency department statistics. 

In addition, hospitals implemented strategies to reduce crowding in waiting rooms, which may have resulted in fewer patients being seen. These strategies included

• Triaging people before they entered the emergency department, either virtually or at the door
• Redirecting those who could be treated elsewhere
• Providing virtual emergency department visits

• What impact did virtual care have on people’s access to care and use of the emergency department?
• What were the health consequences for those who did not go or who delayed going to the emergency department?
• What impact did COVID-19 assessment centres have on emergency department visits?
