People hospitalized with COVID-19 face higher risk of serious health conditions: study

People have heightened risks of developing serious conditions, such as heart failure, dementia and depression, within a year of being hospitalized for COVID-19, similar to those who survive hospitalization for other infectious diseases, like influenza and sepsis, Ontario researchers have found.

In a study, published on Tuesday in JAMA Internal Medicine, the researchers said many of these long-term health outcomes may be related to the severity of patients’ illnesses, rather than a direct consequence of COVID-19 itself.

These findings suggest people require substantial care after they are hospitalized for COVID-19 and other serious infectious diseases, and that the health care system needs to consider how it can better provide that care, particularly to older adults with multiple health conditions, said Toronto clinician-scientist Kieran Quinn, lead author of the study and assistant professor in the University of Toronto’s department of medicine.

“These aftereffects of hospitalization, in general, stand to have a substantial and lasting impact on people and our health care system,” Dr. Quinn said.

He added that the results of the study “reinforce that COVID is – and the aftereffects are – severe, but so are many other health conditions.”

Before seasonal flu patterns were disrupted during the pandemic, influenza caused an estimated 12,200 hospitalizations and 3,500 deaths a year in Canada, with many of those deaths occurring among residents of long-term care.

Patients with COVID-19 logged more than 125,900 hospital stays in Canada between April, 2021, and March, 2022, according to the Canadian Institute for Health Information. The latest federal data show they currently occupy about 2,000 hospital beds per week.

The study analyzed the health data of more than 379,000 adults in Ontario. It compared those who were hospitalized for COVID-19 between April, 2020, and October, 2021, with patients who were hospitalized with influenza before start of the pandemic, and those hospitalized with sepsis, a blood infection, both before and after the start of the pandemic.

COVID-19 was associated with a higher risk of venous thromboembolism, or blood clots, stroke and depression or anxiety within the first 30 days of leaving hospital, the study said. These risks appeared to dissipate after 30 days, it said. Aside from this, it found people hospitalized with COVID-19 did not have a greater risk of developing other new cardiovascular, neurologic or mental-health conditions than their counterparts who were hospitalized with flu or sepsis.

Dr. Quinn said the rates of these conditions, however, are about two to five times higher among people who have survived hospitalization for serious infections than the rest of the population. This is likely because these infections can trigger an overwhelming inflammatory response, which can lead to damage to various organs throughout the body, he said. He emphasized the need to take measures, including vaccination, to prevent serious illness from infections.

Nitin Mohan, an assistant professor in the department of microbiology and immunology at Western University, who was not involved in the study, said the findings are helpful for understanding the health care resources that will be needed to prepare for the long-term effects of COVID-19. He said he hoped to see further studies.

“As we gather more data, as more time passes, we learn more about this virus and how to prepare for it,” Dr. Mohan said.

How many Nova Scotians are on the doctor wait-list? Number hit 160,000 in June

Published

HALIFAX – The Nova Scotia government says it could be months before it reveals how many people are on the wait-list for a family doctor.

The head of the province’s health authority told reporters Wednesday that the government won’t release updated data until the 160,000 people who were on the wait-list in June are contacted to verify whether they still need primary care.

Karen Oldfield said Nova Scotia Health is working on validating the primary care wait-list data before posting new numbers, and that work may take a matter of months. The most recent public wait-list figures are from June 1, when 160,234 people, or about 16 per cent of the population, were on it.

“It’s going to take time to make 160,000 calls,” Oldfield said. “We are not talking weeks, we are talking months.”

The interim CEO and president of Nova Scotia Health said people on the list are being asked where they live, whether they still need a family doctor, and to give an update on their health.

A spokesperson with the province’s Health Department says the government and its health authority are “working hard” to turn the wait-list registry into a useful tool, adding that the data will be shared once it is validated.

Nova Scotia’s NDP are calling on Premier Tim Houston to immediately release statistics on how many people are looking for a family doctor. On Tuesday, the NDP introduced a bill that would require the health minister to make the number public every month.

“It is unacceptable for the list to be more than three months out of date,” NDP Leader Claudia Chender said Tuesday.

Chender said releasing this data regularly is vital so Nova Scotians can track the government’s progress on its main 2021 campaign promise: fixing health care.

The number of people in need of a family doctor has more than doubled between the 2021 summer election campaign and June 2024. Since September 2021 about 300 doctors have been added to the provincial health system, the Health Department said.

“We’ll know if Tim Houston is keeping his 2021 election promise to fix health care when Nova Scotians are attached to primary care,” Chender said.

Newfoundland and Labrador monitoring rise in whooping cough cases: medical officer

Published

 on

 

ST. JOHN’S, N.L. – Newfoundland and Labrador‘s chief medical officer is monitoring the rise of whooping cough infections across the province as cases of the highly contagious disease continue to grow across Canada.

Dr. Janice Fitzgerald says that so far this year, the province has recorded 230 confirmed cases of the vaccine-preventable respiratory tract infection, also known as pertussis.

Late last month, Quebec reported more than 11,000 cases during the same time period, while Ontario counted 470 cases, well above the five-year average of 98. In Quebec, the majority of patients are between the ages of 10 and 14.

Meanwhile, New Brunswick has declared a whooping cough outbreak across the province. A total of 141 cases were reported by last month, exceeding the five-year average of 34.

The disease can lead to severe complications among vulnerable populations including infants, who are at the highest risk of suffering from complications like pneumonia and seizures. Symptoms may start with a runny nose, mild fever and cough, then progress to severe coughing accompanied by a distinctive “whooping” sound during inhalation.

“The public, especially pregnant people and those in close contact with infants, are encouraged to be aware of symptoms related to pertussis and to ensure vaccinations are up to date,” Newfoundland and Labrador’s Health Department said in a statement.

Whooping cough can be treated with antibiotics, but vaccination is the most effective way to control the spread of the disease. As a result, the province has expanded immunization efforts this school year. While booster doses are already offered in Grade 9, the vaccine is now being offered to Grade 8 students as well.

Public health officials say whooping cough is a cyclical disease that increases every two to five or six years.

Meanwhile, New Brunswick’s acting chief medical officer of health expects the current case count to get worse before tapering off.

A rise in whooping cough cases has also been reported in the United States and elsewhere. The Pan American Health Organization issued an alert in July encouraging countries to ramp up their surveillance and vaccination coverage.
