Can I use a mouth shield instead of a mask? Your COVID-19 questions answered – CBC.ca

We’re taking on your questions about the pandemic. Send them to us via email at COVID@cbc.ca, and we’ll answer as many as we can. We’re putting some of your questions to the experts during The National and on CBC News Network. We’re also publishing them here on our website. You’re keeping us busy. So far, we’ve received more than 52,000 emails from across Canada and beyond.

Can mouth shields replace cloth masks?

Mask questions continue to be a major theme in our inbox, but this week, a bunch of you are writing to ask us about mouth shields. The plastic guards cover the lower half of a person’s face and are marketed for stopping the spit of food-service workers.

Tal S. is wondering if they can be worn instead of non-medical masks. 

The experts say no.

“I don’t think they’re a really good alternative at all,” said Dr. Susy Hota, medical director for infection prevention and control at the University Health Network in Toronto, in a recent interview on The National.

“These are developed for the food-service industry, and they’re really not studied or designed for this purpose at all.”

Of course, the purpose of wearing non-medical face coverings, according to public health officials, is to protect others from the droplets spewing from your mouth and nose.

There is also evidence that non-medical masks may offer some protection for the wearer, too. But because mouth shields are not tight fitting and are open at the top, Hota said, there are “lots of opportunities for droplets to get in.” 

“I would avoid using them,” she said.

Colin Furness, an infection control epidemiologist and assistant professor at the University of Toronto, also said he’s “not a fan” because mouth shields don’t collect droplets like a mask would.

“Cloth masks actually get damp,” Furness said in an email. “But I’m guessing [shields] don’t have rivulets of water running down them, and that would be because the droplets aren’t staying.”

Instead, he explained, the droplets are just forced sideways around the shield.

“Full face shields have the same problem,” Furness said. Read more about the issues with face shields here.

I’m hosting an outdoor wedding. Is it OK to dance?

With the gradual lifting of limits on the size of gatherings, Canadians are asking us about good practices for get-togethers.

Joanne L. told us she’s hosting a backyard wedding at her home in Aurora, Ont., but she wasn’t sure if dancing was advisable.

The answer is: It’s complicated.

Dancing, like singing, is one of the activities that is still considered to be higher risk. In some settings, like in restaurants and bars in the province of Ontario, for example, they fall under explicit restrictions and regulations.

For example, performers must:

  • Work for the establishment.
  • Maintain a physical distance of at least two metres from every other person.
  • Be separated from others with a physical barrier, like plexiglass.

However, the Ontario Ministry of Health explained in an email that those regulations don’t apply to events outside of restaurants and bars. 

That means dancing is allowed at your backyard wedding, though distancing and gathering limits still apply. Outdoors, that’s up to 50 people for the service or ceremony and up to 100 people for the reception. 

But just because it’s allowed doesn’t mean it’s without risk. It’s particularly risky, Furness said, because people tend to get close and start breathing harder, “which means expelling more droplets and expelling them further.”

Dr. Anand Kumar, a professor of medicine at the University of Manitoba, added that loud speech, shouting and singing also increase the potential distance of droplet spread. He recommended that guests wear masks “particularly if [there is] loud music which would force participants to shout.”

Health Canada also advises wearing non-medical masks when distancing is difficult. Furness suggested painting big circles on the dance floor, two metres apart, to keep people from getting too close. But he warned that things could become challenging when guests start cutting loose. 

“The problem with a wedding is that it’s not certain that people would keep their mask on or their distance from each other,” he said.

That said, being outdoors would offer “excellent protection,” Furness said, “and either really hot weather or a firm breeze is even more protective.” But the benefits of being outdoors might be reduced if you’ve erected a tent.

If it has open sides with a breeze coming through, Furness said he’d consider that “outdoors.” But if it has walls, it’s indoors.

“I did attend one family dinner in a tent with sides earlier this month, and it was easily the riskiest thing I have done since COVID began,” he said. “I wouldn’t do that again for any reason.”

Is there a safer way to hug?

It’s not just weddings that make people want to get close. The pandemic has left many Canadians longing to wrap their arms around their friends and family.

But what about people not inside your bubble? Carol F. wrote to us to ask if there is a safer way to squeeze them.

“It’s a difficult one to call,” Dr. Lynora Saxinger, an infectious disease physician at the University of Alberta in Edmonton, said in an interview on The National.

“We know that routine closeness can lead to increased transmission.”

Hugs, for example, should be reserved as a “special occasion,” she said.

If you were to give someone a hug, brief contact while wearing masks and with your faces turned away ‘would be the safest way to do it,’ one expert says, adding it would be a good idea to reserve hugs for special occasions. (Mark Lennihan/The Associated Press)

If you were to give someone a special occasion hug, brief contact while wearing masks and with your faces turned away “would be the safest way to do it,” she said.

It might not be a bad idea to hold your breath as well, said CBC News medical contributor Dr. Peter Lin.

Hold your breath before “going in for the hug,” he told CBC News Network. “The virus is not moving at that point.” 

Lin said he even recommends this move to elderly grandparents.

“Once the hug is over, hold your breath again as they pull away, and the virus can’t be breathed into your system.”

That said, physical embraces aren’t without risk, and that might increase when the grandkids go back to school.

“Some people might say, ‘You know what. I’m still OK hugging my grandchildren,'” said Dr. Isaac Bogoch, infectious disease specialist at Toronto General Hospital.  

“Other people might say, ‘The risk is too high, and I’m not going to do this anymore, and we’ll get our hugs in before school starts,'” he said.

Bogoch advised keeping an eye on community transmission in your area. If rates go up, you may want to pump the brakes on close activity with the little ones. We looked at how grandparents might mitigate the back-to-school risks in a previous FAQ.

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.”
