ICU for covid is currently only using around 8% of NSW ICU beds - so let's not get carried away here.
That was 5 days ago. As per NSW health, there are
- 39 public general/combined ICUs with a proportion of units also accommodating quaternary service beds for severe burns, acute spinal injury, organ transplantation and ECMO (provided by 9 adult and 3 paediatric ICUs)*
- 22 private ICUs with 8 providing specialist cardiothoracic intensive care beds and 1 providing specialist neurosurgery intensive care beds
- 2 private high dependency units (HDUs).
* Total number of commissioned adult ICU beds as of July 2021 – 592 (level 4/5/6).
There are currently (25Aug) 113 ICU cases. IE 113/592 = 19%.
ICU and ventilator rates are growing slower than the hospitalisation rates, and certainly slower than the case rates (yes yes, I know there's a lag, but cases have been very consistent at 1.3 for a long time).
So The rate is NOT certainly slower - it is approximaterly 20% of all hospitalisations, but increases by the same rate as Reff of about 1.3.
The shedable load (ie load that can be decreased by stopping elective surgery) is about 30-40%. The other beds are taken by other sick patients such as trauma, heart attacks, sepsis etc.
So when ICU cases hit about 200 there will be no capacity at current resourcing, and surge capacity will be required. Australia has 191 ICUs with 2378 available intensive care beds during baseline activity, (9.4 ICU beds per 100,000 population). Usual staffing is about 1.1 Nurse per bed for 8 or 12 hour shifts. When sick and recreation leave is factored in you need about 8-10 nurses per staffed ICU bed.
Surge capacity is 4258 intensive care beds (191% increase) and 2631 invasive ventilators (120% increase). This could require up to an additional 4092 senior doctors (325% increase over baseline), and 42,720 registered ICU nurses (365% increase over baseline). There are approximately only about 100,000 nurses in NSW, the largest state. This includes medical, surgical, rehab, aged care. They are the nurses who will be looking after you, not a specialist ICU nurse.
The next few weeks will be very hard for NSW, and our thoughts are with you.
Please don't underestimate COVID.
