Should you get another COVID booster? Guidelines are changing

Published

 on

The World Health Organization (WHO) on Tuesday said it no longer “routinely recommends” additional COVID-19 vaccine boosters for medium or low-risk people, but one Canadian doctor is warning the “advice isn’t probably the best.”

The updated roadmap from WHO outlines three priority-use groups for COVID-19 vaccination: high, medium and low, and is designed to prioritize vaccines for those at greater risk of the disease.

The WHO recommended additional booster doses for high-priority groups such as older people, immunocompromised people of all ages, front-line health workers and pregnant people. But for those who fall under the low and medium-risk group, WHO did not recommend additional COVID-19 boosters, citing “low public health returns.”

The WHO’s updated guidance comes just weeks after Canada’s National Advisory Committee on Immunization (NACI) last updated its guidelines on boosters.

“Society is caught between wanting this whole thing to be over and still reconciling that it’s still a threatening problem out there,” Dr. Kashif Pirzada, a Toronto emergency room doctor, told Global News.

“We see plenty of people with just two vaccines who get a fairly brutal illness…the most severe your illness, the more chances you’ll have long-term lingering symptoms. So I think they didn’t really factor that in is that it’s still out there,” he said.

Despite the persistent presence of the highly contagious Omicron variant in Canada, COVID-19 is not expected to surge in the coming months as hospitalizations and deaths remain stable, federal health officials said earlier this month.

On March 10, Canada’s chief public health officer, Dr. Theresa Tam, said that COVID-19 activity has reached a “relatively steady state,” in the country and “we may not see any major waves in the coming months as we prepare for a potential fall and winter surge.”

Because the country is seeing a decrease in deaths relating to COVID-19 infection, Dr. Susy Hota, medical director of infection prevention and control at the University Health Network, said she agrees with WHO’s recommendations.

“I think from a global perspective it makes a lot of sense and probably also makes sense from a Canadian perspective,” she said.

“We know that especially in Canada, younger people have a higher level of hybrid immunity. So having had vaccine doses, but then also prior infections…may offer better protection overall,” she said.

Canada — and the rest of the world — seems to be shifting into a new way of dealing with the disease, she added, which is transitioning into something “more sustainable” for the long term, such as focusing on high-risk individuals.

In terms of where Canada stands on vaccine boosters, Pirzada said there has been little messaging out there, other than a spring shot for high-risk individuals.

 

Canada’s current COVID vaccine recommendations

NACI’s latest guidance on COVID-19 vaccines on March 3 recommended that people facing a high risk of serious illness should get another COVID-19 booster in the spring.

The committee advises all Canadians five years old and up should get immunized against COVID-19 with a full primary series of vaccines. For most people, a primary series is two doses of a COVID-19 vaccine, at a recommended interval of eight weeks apart.

NACI states that “children 6 months to under 5 years of age may be immunized with a primary series of an authorized mRNA vaccine.”

NACI further recommends a booster dose six months after the last dose of a primary course for everyone aged five years old and up.

‘Make a case’ to get booster

Because the most recent NACI guideline is only for high-risk individuals, Pirzada worries, like the WHO, NACI is not taking into account long-term COVID-19 symptoms, which can happen in healthy young people too.

“And the farther out you are from your boosters or from your vaccines, the more chances of having a much more severe course of illness,” he said.

His advice for Canadians is to get a booster if you are six to 12 months out of your vaccine, especially if you’re going to travel or be around large crowds.

If you don’t fall under the high-risk category and want to get boosted, Pirzada said “to make a case” to a physician or pharmacist saying, you’re worried about COVID-19 infection and want a booster.

“Boosters will protect you for three months from infection. That’s pretty good…protection for three months. If you are at high-risk settings in that time where you want to really have fun, that’s not a bad idea,” he added.

Hota believes that low-risk individuals, mainly those who feel nervous about travelling without a booster, should modify their behaviour “if they are concerned.”

The goal of vaccines, she said, is to reduce the risk of severe illness, and if an individual has a very low risk of getting severely sick from COVID-19 (because of hybrid immunity), “it’s probably not going to be offering you that much more protection.”

She stressed that vaccines will have the greatest impact on those at the highest risk.

According to Health Canada, a booster dose of a BA.4/5 bivalent mRNA COVID-19 vaccine “provides increased protection against both symptomatic disease and hospitalization, compared to those who did not receive a bivalent booster dose but received at least two previous doses of original monovalent vaccines in the past.”

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.”
