Recent findings from the Canadian Institute for Health Information (CIHI) reveal alarming trends in hospital admissions linked to COVID-19 and other respiratory infections, with nearly 60,000 Canadians hospitalised in 2024 due to what CIHI categorises as “vaccine-preventable respiratory hospitalisations”. This figure highlights an ongoing public health challenge as vaccination rates continue to decline.
Continuing Pressure on Healthcare Systems
The data indicates that influenza and respiratory syncytial virus (RSV) were responsible for over half of these hospitalisations, while COVID-19 accounted for more than 40 per cent. Melanie Josée Davidson, director of the health system performance team at CIHI, expressed concern over the strain these figures place on healthcare facilities. “While hospitalisations are not at the pandemic levels, 40 per cent of admissions in the past year were still attributed to COVID-19. This is a new reality for us,” Davidson stated.
She further noted that the current hospitalisation rate stands at 142 per 100,000 Canadians in 2024, a significant rise from 66 per 100,000 in 2019. The average length of stay for COVID-19 patients is approximately 23 days, costing about £28,500 per hospitalisation. “Our hospitals are frequently operating above capacity,” Davidson added, underlining a critical issue for health services.
The Ripple Effect on Patient Care
Fahad Razak, an internal medicine physician at St. Michael’s Hospital, identified the increasing number of patients being admitted for respiratory illnesses as a “red flag” for the healthcare system. The influx of patients during respiratory virus seasons adds to the existing burden on hospitals, complicating the treatment of individuals requiring care for unrelated health issues.
“The simultaneous arrival of numerous patients during peak respiratory virus seasons, coupled with COVID-19, places additional pressure on our healthcare system,” Razak remarked. This situation not only strains resources but also impedes the delivery of timely care to those with different medical needs.
Vaccination Rates Decline
Data from the Government of Canada highlights a concerning drop in vaccination uptake. By the autumn of 2024, only 26 per cent of Canadian adults had received a COVID-19 vaccine, with coverage among seniors aged 65 and over at 54 per cent— the highest demographic. For seasonal influenza, vaccination rates were even lower, with just 33 per cent of adults vaccinated during the 2024-2025 season.
Natasha Crowcroft, vice-president of infectious diseases and vaccination programmes at the Public Health Agency of Canada, emphasised the importance of improving public health outreach. “The CIHI report indicates that our public health system is currently failing to adequately reach individuals with the immunisations necessary for their health,” she said.
The Consequences of Low Vaccination
Crowcroft expressed her disappointment over the consequences of low vaccination rates, noting the potential for otherwise healthy individuals to experience severe illness from respiratory infections. “For many, a serious bout of the flu, COVID, or RSV can lead to debilitating conditions,” she explained, highlighting the risks that could result in a need for long-term care.
The report indicated that adults aged 75 and older accounted for nearly half (46 per cent) of all hospitalisations for vaccine-preventable respiratory diseases in 2024. Davidson pointed out that this demographic’s health and recovery capacities are significantly impacted by these illnesses. “Encouraging healthcare providers and caregivers for older individuals to get vaccinated is crucial—not just for their own protection but for the safety of those around them,” Crowcroft said.
A Call to Action
Razak noted that many patients express regret after experiencing serious illness for not having received vaccinations earlier. “Patients often say that after a hospital stay, they will prioritise getting vaccinated next year. It’s akin to wearing a seatbelt—an insurance policy that alleviates worry. I wish more Canadians would adopt this mindset.”
Why it Matters
The surge in hospitalisations due to respiratory illnesses amidst declining vaccination rates signals a critical juncture for Canada’s healthcare system. As hospitals grapple with increased admissions, the need for public health campaigns promoting vaccination becomes ever more urgent. Addressing these challenges not only safeguards vulnerable populations but also strengthens the overall resilience of the healthcare system. Without proactive measures, the cycle of hospital strain and preventable illness is likely to continue, undermining the health of the nation.
