A deputy coroner has ruled that Adelaide librarian Kate Marie Sylvia's death was preventable, finding that critical failures by paramedics and a doctor led to a misdiagnosis that cost the 32-year-old her life in December 2021. The Pembroke Middle School librarian died from a cerebral venous sinus thrombosis after being sent home with a migraine diagnosis, despite exhibiting clear neurological symptoms including slurred speech, vomiting, and stabbing head pain.
Deputy coroner Naomi Kereru found that SA Ambulance should've correctly assessed Ms Sylvia's symptoms and taken her straight to hospital. She also determined that the doctor at the intermediate care centre at Sefton Park, Lyall Henderson, should've referred her to hospital. If either of those opportunities had been taken, Kate would've been sent for a scan which, on the balance of probabilities, would've led to an ultimate diagnosis, Ms Kereru said.
Critical Information Lost
Ms Sylvia's mother, Kathryn Sylvia, had called the ambulance and reported that her daughter couldn't "talk properly" and "sounded like a drunk person." Yet a paramedic didn't record the speech disturbance originally reported to the operations centre and later wrote "no speech disturbance" in his clinical notes. The deputy coroner said the communication between SA Ambulance Service and the hospital avoidance and supported discharge service was overly complicated and contributed to the loss of critical information about Kate's presentation.
Mrs Sylvia told the inquest she'd questioned the doctor after her daughter was given fluids, anti-nausea medication and aspirin and discharged with a migraine diagnosis. She said she told him, "She doesn't normally get migraines," and later asked why her daughter still sounded "groggy" and "slurry." Ms Kereru said the doctor's lack of probing on the issue of Kate's speech was the more fundamental issue. "It is simply good medicine to take the next step of investigation to rule out the most serious condition," she said.
A Diagnosable Condition
In her findings, Ms Kereru said Ms Sylvia was dealing with a condition that's diagnosable on readily-available imaging and has clear treatments that have very good success rates. The overwhelming conclusion was that Kate's death was preventable and that two opportunities were missed.
Ms Kereru made several recommendations to SA Health and the SA Ambulance Service, including that paramedics be reminded of the importance of not filtering information about patients. She also urged that SA Health routine training be updated, and that clinicians be reminded that reports of migraine should be probed in detail and that collateral information about a patient's presentation is valuable, particularly reports that a person being neurologically assessed isn't themselves. She also recommended that SA Health consider a program to allow family members in hospitals to escalate care where they consider concerns aren't being taken seriously.
Outside the SA Coroners Court, Kathryn Sylvia became emotional during her interview with media. Her sister-in-law Denise Botten said, "[Kate was] just a beautiful soul," and Mrs Sylvia said, "I think the main takeaway is clinicians need to listen to family when you think things are not quite right, they need to be sure that they listen."
Dental Care Crisis Deepens
Dentists have warned that one-third of Australian adults are experiencing tooth decay, with many unable to afford dentistry. More than 2 million Australians have skipped dental care because it was unaffordable, according to an Australian Dental Association survey. More than 40 dentists gathered at Parliament House in Canberra to urge politicians to make progress on a national oral health plan.
The federal government hasn't yet finalised its National Oral Health Plan 2025 to 2034, despite consultations with dentists in 2024. ADA vice president Angie Nilsson said, "We're living in one of the richest countries in the world and we still have one-third of adults with untreated tooth decay." She said the problem becomes more expensive, more painful and more time-consuming when people don't go to a dentist early. Dr Nilsson also said 60 per cent of 18 to 25-year-olds are making decisions based on social media, which can lead to bleaching that can be unhealthy and damage teeth.
Emily Novo, a Sydney student, said she felt a slight pain above one of her wisdom teeth while brushing before bed, then woke up the next day unable to open her mouth. "I couldn't even open it enough to brush my teeth, let alone eat a piece of toast," she said, and later, "I was mortified, [I felt] just absolute pure panic." She went to her general practitioner, who couldn't get access to her mouth and sent her to a hospital emergency department. "From a cost point of view, it was really, really daunting," Ms Novo said, and she was sent home with "some hardcore antibiotics." The antibiotics eventually worked, but she was unable to open her mouth properly for a week. "I was just eating soup all week, I couldn't eat properly, I couldn't talk properly," she said.
ADA president Chris Sanzaro said, "Every day in our practices we see the cost of leaving dental care out of the health system," and added, "A National Oral Health Plan is not a luxury; it is essential to giving Australians the access to care they deserve."
Why This Matters:
These findings expose critical gaps in Australia's healthcare system that disproportionately harm ordinary families. Kate Sylvia's preventable death reveals how communication failures and inadequate protocols can turn treatable conditions into tragedies, particularly when medical professionals don't take family concerns seriously. The coroner's recommendation for a family escalation program recognizes that patients and their loved ones must have institutional power to challenge dismissive care. Meanwhile, the dental care crisis demonstrates how excluding essential health services from universal coverage creates a two-tiered system where 2 million Australians can't afford basic preventive care. When one-third of adults in one of the world's wealthiest nations suffer untreated tooth decay, it's a structural failure that demands government action. The delayed National Oral Health Plan leaves vulnerable Australians navigating emergency departments for problems that could've been prevented with affordable early intervention, driving up costs while increasing suffering.
