A new clinic at Sydney Adventist Hospital hopes to reduce the uncertainty and trauma from unexplained blackouts and fainting that could be due to undiagnosed syncope.
The blackout and faints clinic is the first of its kind in Australia set up in a hospital allowing a patient the benefit of access to a range of multi-disciplinary trained medical specialists who share their expertise to diagnose and recommend treatment.
Presenting as a transient loss of consciousness due to a lack of blood supply to the brain, syncope can be a sign of a range of conditions and has been attributed to twice the incidence of death in cardiac patients, serious head and hip injuries, car and work-related accidents.
One in two Australians are expected to suffer from syncope during their lifetime and one in five will suffer recurrent episodes, making it the fifteenth most common cause of presentations to emergency care departments, and the fifth most common cause of emergency care admissions to hospitals.
"While in most cases the cause may be benign, you should not take the risk that it’s not a sign of something more sinister."
Lack of knowledge about syncope can result in inappropriate and expensive medical referrals and tests, creating long and potentially dangerous delays to finding a diagnosis. It has been estimated public healthcare costs of syncope exceed $A127 million each year.
San cardiologist and clinical director of the new clinic, Dr Maros Elsik, said syncope is frequently challenging to diagnose and manage.
“Published reports estimate that 90 per cent of people who blackout or faint don’t actually end up seeing a doctor,” Dr Elsik said.
“When they do their syncope may be found to be due to cardiac, neural, or due to multiple other issues, however in over 36 per cent of cases, the cause is not successfully identified at all.
“While in most cases the cause may be benign, you should not take the risk that it’s not a sign of something more sinister.
“Additionally, not knowing the cause of why you are fainting, leaves people in limbo, fearful when it might happen again, a particular concern to patients aged 60 and over who seem most commonly affected.”
San geriatrician Dr Ketan Bhatt noted the significant overlap between fainting and falling.
“Falls in the elderly are significant events that can threaten their independence and lead to injuries, loss of confidence and post-fall anxiety,” Dr Bhatt said.
“One of the more feared complications of a fall is a hip fracture, which can have a devastating impact on an older person’s overall health. Importantly, studies estimate around 7 per cent of those suffering hip fracture will die within 30 days.”
San cardiologist Dr Peter Illes advised that correct diagnosis and management can save lives.
“We know that almost 1 in 10 cases of syncope are due to a cardiac condition and that sadly those patients have a 10 per cent greater risk of death within six months of their first episode of syncope.
“Thankfully however, if diagnosed with cardiac syncope, appropriate treatment measures can be instituted. These could include education about preventing or reducing it occurring, advice to start or stop certain medication, or specific treatments such as pacemakers and other cardiac interventions.
“If someone is initially sent to a neurologist they will get a lot of neurological investigations which may not actually be appropriate. The clinic offers a screening process that means patients go down a more appropriate cost-effective investigation pathway and process.”
“If a patient’s diagnosis is uncertain, or their existing treatments have not reduced the frequency of their blackouts and faints, or its cause has not been diagnosed, that’s where the value of this clinic comes into its own,” Dr Elsik said.
“I believe it will reduce excessive testing and healthcare costs, shorten the time until diagnosis and give patients access to allied health services and specialised medications only available in a hospital. It will also increase opportunities for clinical research so we can improve how we help more people in the future.”
