Some food for thought:
If you click on the xlsx file referenced in the above article, you will notice that there was a sometimes signifiant decrease in hospital activity across the board from March to November 2020 compared to 2019 (December was about the same). That includes overall admissions, ICU admissions, ventilator use, etc. I’d be curious to see how the 2019 numbers compare with early 2021 but I cannot find those numbers.
The following report from 2014 (a more recent study would be welcomed) shows that Canadian ICUs in urban areas spend 45 to 51 days per year above capacity on average.
That being said, I certainly feel for health care workers in this difficult time (there are a few in my family), but I think that the increase in workload and stress levels have more to do with the change in protocols (having to separate COVID patients and non-COVID patients, having to sanitize/change equipment more often, more administrative work) and staffing levels (senior health care workers retiring early, more people calling in sick due to any little symptom, as they are asked to do) than anything else.
There has been a shortage of nurses for as long as I can remember, and unfortunately these factors have only exacerbated the situation.
