'Science is working': Canadian experts say evolving mask guidance to be expected – CTV News

Published

 on


Public health messaging over face masks changed again this week when the U.S.-based Centers for Disease Control and Prevention (CDC) updated its guidance to say face coverings can help protect the wearer as well as those around them.

The new guidance, which landed on the CDC website on Tuesday, cited recent studies suggesting multi-layer cloth masks can “reduce inhalation of … droplets by the wearer.” Previous guidance said masks were useful primarily in blocking the wearer’s droplets from reaching others.

The CDC’s update now matches recommendations from both Health Canada and the World Health Organization (WHO). The Public Health Agency of Canada (PHAC) said in an emailed statement on Wednesday that “wearing a mask can help protect the wearer and others.”

However, this message seems to have been muddled due to previous conflicting guidance, which has mostly emphasized masks as a way to protect those around you.

Canadian health experts are also divided on whether the updated CDC guidance is helpful – some hope it can convince reluctant people to start wearing face masks, while others worry the message may be misinterpreted.

Dr. Amy Tan, a clinical assistant professor at the University of Calgary and member of the physician group Masks4Canada, says the “evidence has been there since August” to show that cloth masks, provided they fit well and are made of three layers with a polypropylene filter, do protect the wearer.

And if that can persuade people to wear one, so be it.

“If the small inconvenience of wearing your mask isn’t enough to appeal to the collective good, then now we can say: ‘it can protect you too, so wear it,”’ Tan said.

Colin Furness, an assistant professor at the University of Toronto’s School of Public Health, isn’t convinced the updated guidelines are accurate.

While he isn’t ruling out the possibility that cloth face masks might help protect those wearing them, he says people need to remember the caveats – three layers plus a good fit – to that claim.

“If (the CDC) is trying to appeal to peoples’ sense of self-preservation by saying: ‘masks could protect the wearer, therefore you should wear a mask,’ that could be a way to motivate people.

“But on the other hand, I don’t endorse that because it could make people think ‘OK, I can put on a mask and it’s substitutable for physical distancing.”’

The CDC update is the latest in what’s been an evolving policy on mask-wearing over the last eight months.

Face masks were discouraged by many public health officials in Canada back in March, with some saying a home-made covering could actually lead to further spread if it meant constantly touching the face to make adjustments. The discourse then shifted to say masks were useful in protecting others, but not ourselves.

Tan says changes in guidance show “science is working.” And advancements are made in all facets of medicine on a daily basis.

“We’ve never lived in a time where we had a global pandemic,” she said. “In eight months there’s been a lot more science generated…. We’re just seeing this happening publicly and in a very compressed time.”

PHAC also acknowledged that, saying “the government is continually reviewing new evidence and research” and that new evidence guides its recommendations.

Furness agrees that public health policy was expected to change as we learned more about the virus and how it’s transmitted.

He said every expert – himself included – could point to things they got wrong about COVID back in March, when a mask’s ability to “disrupt the ejection of droplets” wasn’t really taken into consideration.

“It was just a giant blind spot,” he said.

“I mean, think about our knowledge back then. Everyone was afraid and we didn’t know much.”

Dr. Christopher Labos, a Montreal-based physician, says COVID-19 was looked at in the same way as SARS or the flu in the early stages of the pandemic. With both of those viruses, people tend to be very symptomatic and infectious when showing symptoms.

“The original messaging was if you have no symptoms, there’s no point in wearing a mask because you’re probably not sick,” he said.

“But what’s changed is the growing realization that a lot of people have coronavirus and don’t know it. So guidelines shifted to suggest a universal masking policy, because you don’t know if you’re walking around with the virus.”

Labos also believes there may have been reluctance to promote face masks in the early stages of the pandemic out of fear people would confuse “the different mask categories, and what their roles are.”

N-95 respirators, worn by medical professionals in high-risk situations, offer “almost complete protection,” because of their tight seal around the face. But a surgical mask or home-made cloth face covering won’t protect the wearer to that degree.

“It probably does protect you a little bit … but in terms of quantifying it, in terms of saying it with any degree of certainty, that becomes a lot more complicated,” Labos said.

The experts say it’s important to remember that mask-wearing should be viewed as just one component of the public health strategy.

“A mask doesn’t prevent infection, but it drastically reduces the chance of infection,” Labos said. “And that certainly helps.”

Older patients, non-English speakers more likely to be harmed in hospital: report

Published

 on

 

Patients who are older, don’t speak English, and don’t have a high school education are more likely to experience harm during a hospital stay in Canada, according to new research.

The Canadian Institute for Health Information measured preventableharmful events from 2023 to 2024, such as bed sores and medication errors,experienced by patients who received acute care in hospital.

The research published Thursday shows patients who don’t speak English or French are 30 per cent more likely to experience harm. Patients without a high school education are 20 per cent more likely to endure harm compared to those with higher education levels.

The report also found that patients 85 and older are five times more likely to experience harm during a hospital stay compared to those under 20.

“The goal of this report is to get folks thinking about equity as being a key dimension of the patient safety effort within a hospital,” says Dana Riley, an author of the report and a program lead on CIHI’s population health team.

When a health-care provider and a patient don’t speak the same language, that can result in the administration of a wrong test or procedure, research shows. Similarly, Riley says a lower level of education is associated with a lower level of health literacy, which can result in increased vulnerability to communication errors.

“It’s fairly costly to the patient and it’s costly to the system,” says Riley, noting the average hospital stay for a patient who experiences harm is four times more expensive than the cost of a hospital stay without a harmful event – $42,558 compared to $9,072.

“I think there are a variety of different reasons why we might start to think about patient safety, think about equity, as key interconnected dimensions of health-care quality,” says Riley.

The analysis doesn’t include data on racialized patients because Riley says pan-Canadian data was not available for their research. Data from Quebec and some mental health patients was also excluded due to differences in data collection.

Efforts to reduce patient injuries at one Ontario hospital network appears to have resulted in less harm. Patient falls at Mackenzie Health causing injury are down 40 per cent, pressure injuries have decreased 51 per cent, and central line-associated bloodstream infections, such as IV therapy, have been reduced 34 per cent.

The hospital created a “zero harm” plan in 2019 to reduce errors after a hospital survey revealed low safety scores. They integrated principles used in aviation and nuclear industries, which prioritize safety in complex high-risk environments.

“The premise is first driven by a cultural shift where people feel comfortable actually calling out these events,” says Mackenzie Health President and Chief Executive Officer Altaf Stationwala.

They introduced harm reduction training and daily meetings to discuss risks in the hospital. Mackenzie partnered with virtual interpreters that speak 240 languages and understand medical jargon. Geriatric care nurses serve the nearly 70 per cent of patients over the age of 75, and staff are encouraged to communicate as frequently as possible, and in plain language, says Stationwala.

“What we do in health care is we take control away from patients and families, and what we know is we need to empower patients and families and that ultimately results in better health care.”

Alberta to launch new primary care agency by next month in health overhaul

Published

 on

 

CALGARY – Alberta’s health minister says a new agency responsible for primary health care should be up and running by next month.

Adriana LaGrange says Primary Care Alberta will work to improve Albertans’ access to primary care providers like family doctors or nurse practitioners, create new models of primary care and increase access to after-hours care through virtual means.

Her announcement comes as the provincial government continues to divide Alberta Health Services into four new agencies.

LaGrange says Alberta Health Services hasn’t been able to focus on primary health care, and has been missing system oversight.

The Alberta government’s dismantling of the health agency is expected to include two more organizations responsible for hospital care and continuing care.

Another new agency, Recovery Alberta, recently took over the mental health and addictions portfolio of Alberta Health Services.

Experts urge streamlined, more compassionate miscarriage care in Canada

Published

 on

 

Rana Van Tuyl was about 12 weeks pregnant when she got devastating news at her ultrasound appointment in December 2020.

Her fetus’s heartbeat had stopped.

“We were both shattered,” says Van Tuyl, who lives in Nanaimo, B.C., with her partner. Her doctor said she could surgically or medically pass the pregnancy and she chose the medical option, a combination of two drugs taken at home.

“That was the last I heard from our maternity physician, with no further followup,” she says.

But complications followed. She bled for a month and required a surgical procedure to remove pregnancy tissue her body had retained.

Looking back, Van Tuyl says she wishes she had followup care and mental health support as the couple grieved.

Her story is not an anomaly. Miscarriages affect one in five pregnancies in Canada, yet there is often a disconnect between the medical view of early pregnancy loss as something that is easily managed and the reality of the patients’ own traumatizing experiences, according to a paper published Tuesday in the Canadian Medical Association Journal.

An accompanying editorial says it’s time to invest in early pregnancy assessment clinics that can provide proper care during and after a miscarriage, which can have devastating effects.

The editorial and a review of medical literature on early pregnancy loss say patients seeking help in emergency departments often receive “suboptimal” care. Non-critical miscarriage cases drop to the bottom of the triage list, resulting in longer wait times that make patients feel like they are “wasting” health-care providers’ time. Many of those patients are discharged without a followup plan, the editorial says.

But not all miscarriages need to be treated in the emergency room, says Dr. Modupe Tunde-Byass, one of the authors of the literature review and an obstetrician/gynecologist at Toronto’s North York General Hospital.

She says patients should be referred to early pregnancy assessment clinics, which provide compassionate care that accounts for the psychological impact of pregnancy loss – including grief, guilt, anxiety and post-traumatic stress.

But while North York General Hospital and a patchwork of other health-care providers in the country have clinics dedicated to miscarriage care, Tunde-Byass says that’s not widely adopted – and it should be.

She’s been thinking about this gap in the Canadian health-care system for a long time, ever since her medical training almost four decades ago in the United Kingdom, where she says early pregnancy assessment centres are common.

“One of the things that we did at North York was to have a clinic to provide care for our patients, and also to try to bridge that gap,” says Tunde-Byass.

Provincial agency Health Quality Ontario acknowledged in 2019 the need for these services in a list of ways to better manage early pregnancy complications and loss.

“Five years on, little if any progress has been made toward achieving this goal,” Dr. Catherine Varner, an emergency physician, wrote in the CMAJ editorial. “Early pregnancy assessment services remain a pipe dream for many, especially in rural Canada.”

The quality standard released in Ontario did, however, prompt a registered nurse to apply for funding to open an early pregnancy assessment clinic at St. Joseph’s Healthcare Hamilton in 2021.

Jessica Desjardins says that after taking patient referrals from the hospital’s emergency room, the team quickly realized that they would need a bigger space and more people to provide care. The clinic now operates five days a week.

“We’ve been often hearing from our patients that early pregnancy loss and experiencing early pregnancy complications is a really confusing, overwhelming, isolating time for them, and (it) often felt really difficult to know where to go for care and where to get comprehensive, well-rounded care,” she says.

At the Hamilton clinic, Desjardins says patients are brought into a quiet area to talk and make decisions with providers – “not only (from) a physical perspective, but also keeping in mind the psychosocial piece that comes along with loss and the grief that’s a piece of that.”

Ashley Hilliard says attending an early pregnancy assessment clinic at The Ottawa Hospital was the “best case scenario” after the worst case scenario.

In 2020, she was about eight weeks pregnant when her fetus died and she hemorrhaged after taking medication to pass the pregnancy at home.

Shortly after Hilliard was rushed to the emergency room, she was assigned an OB-GYN at an early pregnancy assessment clinic who directed and monitored her care, calling her with blood test results and sending her for ultrasounds when bleeding and cramping persisted.

“That was super helpful to have somebody to go through just that, somebody who does this all the time,” says Hilliard.

“It was really validating.”
