That’s the conclusion of a new study by researchers at the Ontario-based Lawson Health Research Institute, Western University, and ICES.

Prior to the pandemic, less than 2 per cent of patient visits with physicians took place virtually. In the early months of the pandemic (April-June 2020), there was a rapid transition to virtual visits, which soared to 70 to 80 per cent, before falling back and stabilising at 50 to 60 per cent of all physician visits.

This cross-sectional study, published in JAMA Network Open, used healthcare administrative data from Ontario, Canada to identify all patients with at least one virtual care visit between March 2020 and December 2021.

Findings show that for more than 10 million patients with at least one appointment during the study period (63 million visits in total), virtual care was associated with estimated savings of: 3.2 billion kilometres of patient travel; 545 to 658 million kilograms of carbon dioxide (CO₂) emissions; and CAD$569 to CAD$733 million in expenses for fuel, parking, or public transit.

The avoidance of carbon dioxide emissions during the pandemic due to virtual visits represented about 0.2 per cent of the total annual carbon dioxide emissions (150 megatons) from Ontario.

“Virtual care has become an important part of the healthcare system in Ontario, and in addition to improved patient convenience, it results in significant environmental and financial benefits for patients,” says lead author Dr Blayne Welk, associate professor of surgery at Western, urologist at St Joseph’s Health Care London, associate scientist at Lawson, and adjunct scientist at ICES Western.

“The financial and environmental benefits of virtual care will likely continue beyond the pandemic and are particularly relevant for some patients who were frequent recipients of virtual care.”

The number of virtual care visits was greater for those aged 65 and older, individuals with multiple health conditions, and those living in urban areas. Owing to distance travelled, virtual care may offer more potential environmental benefits and patient cost savings for rural residents. Other factors, such as decreased time off work, may have had additional benefits for some working adults and parents of young children.

“Virtual visits should not replace all in-person visits, but they’re an important option that can enhance the care that physicians provide for patients,” says Dr Alexandra Zorzi, a paediatric oncologist at Children’s Hospital at London Health Sciences Centre and associate scientist at Lawson.

“Our findings suggest that physicians should continue to offer virtual care appointments when appropriate, especially for patients living in more remote areas and those who have barriers to accessing in-person healthcare.”
