New data from the Canadian Institute for Health Information (CIHI) has revealed concerning hospitalisation rates stemming from COVID-19 and other respiratory infections, as vaccination uptake declines significantly. In 2024, nearly 60,000 Canadians found themselves hospitalised due to what CIHI categorises as “vaccine-preventable respiratory hospitalisations.” With influenza and respiratory syncytial virus (RSV) accounting for over half of these cases and COVID-19 contributing to more than 40%, the strain on the healthcare system is palpable.
Alarming Trends in Hospitalisation Rates
The recent figures indicate that hospitalisation rates have surged to 142 per 100,000 Canadians in 2024, a stark increase from just 66 per 100,000 in 2019. Melanie Josée Davidson, CIHI’s director for health system performance, commented on the ongoing challenge: “While the situation is not as dire as during the height of the pandemic, COVID-19 continues to account for a significant portion of hospitalisations. This is now a sustained issue that our healthcare system must contend with regularly.”
Davidson went on to emphasise the considerable burden these hospitalisations place on healthcare facilities. “Our hospitals are frequently operating above capacity, which complicates the delivery of care for patients with other medical needs,” she added. The average length of a COVID-19 hospital stay is approximately 23 days, resulting in an average cost of around £28,500 per case.
The Impact on Healthcare Delivery
Dr. Fahad Razak, an internal medicine physician at St. Michael’s Hospital, articulated the difficulties that healthcare professionals face amid these rising hospitalisation rates. He described it as “one of the toughest aspects of the job” to witness the influx of patients due to respiratory illnesses, labelling the current capacity challenges as a “red flag.”
“The solutions, such as increasing staffing levels and bed availability, are not immediate fixes,” Razak explained. “Building new hospitals can take a decade from initial funding to becoming operational. As Canadians, we must work collectively to optimise the existing healthcare system.”
The pressure from respiratory illness admissions is not just an issue in isolation. It significantly impacts the treatment of patients entering the healthcare system for unrelated conditions. “When there’s a surge in patients during respiratory virus season, along with COVID-19, it creates unnecessary strain on an already burdened system,” Razak noted.
Declining Vaccination Rates
Statistics from the Government of Canada indicate that vaccination rates have sharply declined, with only 26 per cent of adults vaccinated against COVID-19 in the autumn of 2024. Among seniors aged 65 and older, the coverage was somewhat higher at 54 per cent. For the 2024-2025 influenza season, just 33 per cent of adults received their flu vaccine.
Natasha Crowcroft, vice-president of infectious diseases and vaccination programmes at the Public Health Agency of Canada, expressed concern over these figures. “The CIHI report highlights a significant gap in our public health approach to immunisation, which is crucial for keeping our population healthy,” she stated.
Consequences of Low Vaccination Uptake
The ramifications of low vaccination rates are profound. Crowcroft lamented, “It’s tragic that many individuals who might not need to be hospitalised end up in that situation due to preventable infections like flu, COVID-19, or RSV. For previously healthy individuals, these infections can lead to severe health declines, potentially necessitating long-term care.”
The CIHI report further indicates that adults aged 75 and older represent nearly half (46 per cent) of all hospitalisations for vaccine-preventable respiratory diseases. Davidson stresses the importance of vaccination not just for individual health but also for the wider community. “We encourage healthcare providers and caregivers of older adults to prioritise vaccinations, as it protects both individuals and those around them,” she said.
Dr. Razak reiterated that many hospitalised patients express regret at not having received their vaccinations earlier. He compared vaccination to wearing a seatbelt, describing it as a vital insurance policy. “For those who suffer severe illness, they often vow to get vaccinated in the future after experiencing the consequences of their choices,” he reflected. “I hope more Canadians begin to view vaccination in this light.”
Why it Matters
The data from CIHI serves as a stark reminder of the continuing impact of COVID-19 and other respiratory illnesses on Canadian healthcare. The combination of rising hospitalisation rates and declining vaccination uptake creates a precarious situation, threatening to overwhelm our healthcare system. Prioritising vaccination could alleviate this burden and enhance the health and well-being of individuals and communities alike. As we navigate the complexities of public health, it becomes increasingly clear that proactive measures—such as vaccination—are essential in safeguarding the health of our population and ensuring that our healthcare system remains resilient in the face of ongoing challenges.
