Baby diagnosed with a sprain had actually suffered a stroke

An Ontario mother says she had to take her baby to three different hospitals, and speak with six doctors in less than a week, to get an accurate diagnosis after he was injured in a fall.

"It's been traumatizing and it still haunts me," Sana Tayab-Mohammad, 34, told Go Public.

Her son Uzair, 11 months old at the time, was twicediagnosed with a sprained arm. In fact, he'd had a stroke and was suffering from partial paralysis.

Tayab-Mohammad says she understands it's highly unusual for a baby to have a stroke, but believes doctors should have seen that the baby's condition couldn't be the result of a simple sprain.

"His left side was not functioning at all. His head was tilted to the left," she said. "He had little movement in his arm, his left hand was clenched, and his left leg and foot had little movement."

Studies show misdiagnosis affects 10 to 15 per cent of people who arrive at hospital emergency departments, according to an emergency roomdoctor who has studied and written a book about diagnostic failure.Dr. Patrick Croskerry, who teaches at the Dalhousie School of Medicine in Halifax,says themost commonailmentslikely to be misdiagnosed in ERs are heart attacks, sepsis and stroke.

Doctors have been known toconclude such patients are suffering from minor problemsand send them home, telling them to follow up with their family doctor, or returnto the ER if there's a significant change, he says.

Croskerry expectsthe pandemic has made misdiagnosis more likely.

"People are working extraordinarily hard every day, and we know from the cognitive sciences literature that when people work hard, their decision-making is compromised," he told Go Public. He expects studies will be done once the COVID-19 crisis is over, to calculate the impact on emergency rooms. He saida negative effectseems"inevitable,"due to the additional workload and stress created by the pandemic.

"Talking to colleagues, it is clear that everyone is expecting it," he said.

The Mohammad family's disturbing experience began during a visit to Ajax, Ont.,on Aug.28.The baby was crawling and tried to sit up, but fell backward and hit his head on the floor.

An Ontario mother said she had to take her baby to three different hospitals, and speak with six doctors in less than a week, to get an accurate diagnosis after he was injured in a fall. Her son was twice diagnosed with a sprained arm, but he'd had a stroke and was suffering from partial paralysis.

Shortly after, the parents noticed the problems with his left side. They rushed him to nearby Lakeridge Health Ajax Pickering Hospital, where an emergency room doctor diagnosed a sprain.

Two days later, the baby's health hadn't improved. "He wasn't eating. He wasn't playing. His behaviour was down and there was still no movement on his left side," his mothersaid.

They took Uzair to the Hospital for Sick Children in Toronto, where again, a sprain was diagnosed.

Diagnosticmomentum

Dr.GurinderSangha, who heads the pediatric division ofthe Canadian Association of Emergency Physicians, says there's no question it's difficult to determine what is wrong witha child whocan't yet speak for themselves.

"It'san extra layer of complexity because the patient can't tell you what they are experiencing," he told Go Publicfrom the ER where he works in London, Ont.

Sanghasays diagnosing rareconditions is difficult at the best of times. "When you add the challenges associated with the pandemic, you are also seeing front-line staff burnout. So it's all made the job of diagnosing much more difficult."

He pointedto the workload and stress created by the COVID-19 crisis. His ER saw its highest volume of patients ever in October.

"It's about 130 per cent to 140 per centof normal andIbelieve that is the case with ERs across the country,"he said.

Croskerry said he is unable to comment directly on Uzair's case, but explained a phenomenon known as "diagnosis momentum" when an initial, incorrect diagnosis is made and then influences subsequent examinations, causing hospital staff to echo and build onwhat medical professionals have previously reportedabout the cause of a problem.

"A diagnosis can get established early in the contact with the health-care system," said Croskerry. "And then, as the patient continues through the system, people develop a stronger conviction about what's happening. But they're actually inheriting thinking that may not have been correct in the first place."

He saidemergency medicine has been describedas a "natural laboratory for error,"due to the often chaotic environment in ERs, and the strain put on doctors by long hours and shift work. The pandemic and the need for masks haveadded a furtherchallenge, since facial expressions that could aid diagnosis can't be observed.

Tayab-Mohammad wanted to trust the diagnosis given by doctors at Lakeridge Health and the Sick Children's Hospital, and tried to convince herself it was accurate.

But as the child continued to struggle, she and her husband couldn't shake their fears.She called their family doctor who recommended they take Uzairto yet another hospital's emergency room, and insist on further investigation.

Only then five days after the fall did a CT reveal that the child had suffered a stroke.

At that point the situation became an emergency. An ambulance and medical team were dispatched from Sick Children's Hospital to bring the child and mother from Barrie. An MRI confirmed what the CT scan had found. It was recommended he take aspirin every day until he's two years old, and that he receive rehabilitation therapy.

Underlying condition

Thankfully, after two and a half weeks in hospital, Uzairhas recovered, although his parents have been told he has a rare condition called mineralising angiopathy, where blood vessels in the brain become rigid or brittle. It means even a minor head injury puts him at an increased risk of stroke.

His parents are grateful and relieved to finally have an accurate understanding of his condition. As he grows,Uzairwon't be able to participatein activities where falls are likely.

After hearing from Go Public, the Hospital for Sick Children and Lakeridge Health Ajax Pickering Hospital contacted the family to discuss what happened. Neither hospital would agree to an interview, citing patient confidentiality,

In a statement to CBC News, the Hospital for Sick Children said its emergency department sees 82,000patients a year. "In contrast, SickKids Division of Neurology has seen only 14 patients with Uzair's condition since 2002."

The statement also offered an explanation for why a more comprehensiveinvestigation wasn't done sooner, noting that CTscans carry risks related to radiation. Young children often need to be sedated for CT andMRI scans, which presents another risk and must be considered in balance with the potential diagnostic benefit.

"Uzair's case highlights the need for increased awareness of paediatric stroke," said the statement, "and has been identified as one that will be reviewed as a teaching opportunity."

Lakeridgedidn't offer acomment,but Tayab-Mohammad says both hospitals tried to explain why the error was made, and apologized for the ordeal.She has filed acomplaint with the College of Physicians and Surgeons of Ontario.

How to handle a suspected misdiagnosis

Patients who believe they may have been misdiagnosedshould notbluntly tell a physician they are wrong, says Croskerry.

He says it's best to ask: "What else could be going on?"

"When you do that, you open up the possibilities," he said. "And as soon as they start articulating the possibilities, what tends to happen is that they put themselves into a different style of thinking tied to reasoning, and that tends to be much more reliable."

Asked what she wants Canadians to understand from her experience, Tayab-Mohammad said: "I want them to be persistent to get the answers they need. You know your child, you know when something's wrong, and don't ignore it."
