The study found that rural patients examined with the aid of a technology called Telestroke received an important stroke drug, tPA, at the same rate as patients treated in specialised urban centres, says Doctor Thomas Jeerakathil, a neurologist at the University of Alberta Hospital. The drug tPA (tissue plasminogen activator) is used to break up blood clots. It can help reverse stroke damage if administered within 4.5 hours of the onset of symptoms.
"Telestroke is a way to bring the expert out to the rural centre to provide treatment that wouldn't otherwise be available," Jeerakathil says. "And there is no delay in treatment despite the time required to set up video conferencing equipment and examine CT scans and blood work."
In the study, an initiative of the Alberta Provincial Stroke Strategy, University of Alberta Hospital neurologists observed the use of Telestroke in 10 primary stroke centres throughout remote parts of Northern Alberta over a four-year period.
During this time, tPA was administered to more than 500 people and, of those, 119 patients were treated with the help of Telestroke. Without access to the technology, these patients would have gone without treatment or been transferred to a bigger hospital and faced delays, says Jeerakathil.
Effective Telestroke treatment in remote areas contributed to a 50 per cent decrease in emergency room transfers from rural areas to the University Hospital in Edmonton, says Jeerakathil. Some remote hospitals reported a decrease in transfers as high as 92 per cent.
"Cost savings are occurring while outcomes are improving and stroke mortality is decreasing in the province," says Jeerakathil.
Telestroke allows small hospitals to be designated as primary stroke centres with many of the services of a major stroke unit. These primary stroke centres have a small sectioned off area with staff specially trained in stroke care, 24-hour access to a CT scan and the ability to give tPA.
"Telestroke is severely under-utilised in Canada," says Doctor Antoine Hakim, CEO and Scientific Director of the Canadian Stroke Network. "An audit of stroke care in Canada showed that less than 1 per cent of stroke patients received a Telestroke consultation. This study undeniably proves that Telestroke saves both lives and money."
