Who gets a ventilator? In ‘hypothetical’ worst-case scenario, age might decide

The Saskatchewan Health Authority has offered an early glimpse at some of the factors health care teams might weigh to decide which COVID-19 patients get ventilators if there are not enough to go around.

Dr. Susan Shaw, the SHA’s chief medical officer, said the details are still being finalized and, at the moment, remain hypothetical.

“We’re not there right now,” Shaw said in an interview Thursday.

While it’s not clear, cumulatively, how many of Saskatchewan’s 206 COVID-19 cases have needed a ventilator, the maximum number of coronavirus cases who have been under intensive care (ICU) at the same time has been two.

As of Thursday, four COVID-19 patients were in hospital in the province, including two people in ICU.

Shaw’s colleague Dr. Saqib Shahab — Saskatchewan’s chief medical health officer and the public face of the province’s fight to “flatten the curve” — said it’s hard to know when the province might reach its infection peak.

“Obviously at some point we want to see the curve going down. Is that going to be in four weeks, eight weeks? We really can’t predict,” he said on Wednesday.

The province currently has 450 ventilators and has ordered hundreds more. One early-draft planning doc, leaked last week, estimated that at peak infection time, Saskatoon alone might need 500 to 600 ventilators at a time.

Health officials in Saskatchewan and elsewhere have undertaken the grim but necessary exercise of contemplating who would get a ventilator should hospitals be swarmed with serious cases while not having enough machines to go around.

“One of the main purposes of actually having this work done in preparation is a part of our responsibility to avoid arbitrary decisions,” Shaw said.

“Right now the decisions are made about what’s best for the individual. And when you get into a situation where you’re starting to actually face scarcity, the ethical principles shift to be what’s best for society.”

Age is not the only factor

Decisions about which patients would get ventilators would be made by doctors and members of the health authority’s ethics commities, Shaw said.

The age of patients is a key consideration, but not the only one, she said.

“It’s actually one of a combination of criteria,” she said. “To make decisions solely on age would be discriminatory and would not be the way we would want to approach this. It’s age in combination with frailty, chronic disease and recoverability.”

In the “extremely unlikely” scenario where two patients’ criteria lined up exactly, the ventilator would go to the younger patient, Shaw said.

“That’s based on the principle called the goal of the life cycle, which is every individual needs to have the equal opportunity to live through the various phases of life.”

No one would completely stop being cared for, however.

“That always applies no matter what the situation is,” Shaw said. “This means making sure that we never abandon the patient.”

Medical health professionals elsewhere have also contemplated the notion of a lottery.

While Shaw stressed that that option is not in Saskatchewan’s current way of thinking, she is familiar with the concept.

“My understanding is that if you ever got into a tiebreaker situation where absolutely everything [including age] was identical — and again I think this is absolutely hypothetical — then a lottery is one of the ways that you could tackle that.”

Updates coming next week

Premier Scott Moe said Thursday that he had asked the health authority to publicly release updated projections of how many people in the province might become infected and die from the virus, under various scenarios.

That update — which will also touch on planning for field hospitals and COVID-19 care in existing hospitals — is expected early next week.

“They all do fit together,” Shaw said of the modelling, the operational plan and the ethical framework for decision-making.

“We want to share it,” she said of the ethical framework. “It’s not quite ready to be shared but it is ready to start being talked about.”

‘None of this can be rushed’

Another aspect of Saskatchewan’s pandemic planning has come to light thanks to a Facebook post on Thursday.

A health care worker shared photos of herself and colleagues at Royal University Hospital clothed in face shields, gloves and full-body suits. They were practicing intubation on “Harold.”

“Harold is a simulation dummy for the newly formed intubation teams to practice on,” the worker wrote. “We are teams of anaesthesiologists, AAs and nurses who practice and train day or night every shift until there is a real patient with COVID-19 who cannot breathe on their own.

“I am grateful that we have this time to get prepared,” the worker added.

Shaw confirmed this type of COVID-19-specific training has gone on for at least two weeks.

“Putting a breathing tube in somebody is a very routine activity for an anesthesiologist and many other health care professionals,” Shaw said. “But how do you do it [properly] while appropriately donning and doffing equipment?”

Shaw even joined in the exercise later on Thursday.

“Proud of my colleagues. We are in good hands,” Shaw wrote on Twitter.

The health care worker who posted on Facebook said putting on and taking off equipment takes a long time, but with good reason.

“So that we health care people can be as safe as we can,” she wrote. “None of this can be rushed as staff safety is the number one priority.”

During Thursday’s provincial COVID-19 news conference, Moe said the procurement of more personal protective equipment (PPE) for front-line workers was his top priority on a call that same afternoon with Prime Minister Justin Trudeau and other premiers.

The health worker wrote in their Facebook post that the trainees weren’t wearing N95 masks in order to “save them for when they are actually needed.”

At the same provincial news conference, Shahab cited instances where it was not initially known a patient had respiratory symptoms and so health care workers were not wearing the right PPE.

Shahab said patients should always phone a clinic instead of just going there.

The health care worker training for COVID-19 intubation had some advice too.

“You definitely don’t want to become a Harold. Stay home, and stay safe.”
