London, August 4 : Establishing audio-video contacts between doctors and patients through the internet may have an immediate and profound impact on the treatment of stroke patients throughout the world, say researchers.
Dr. Brett C. Meyer, Co- Director of the UC San Diego Medical Center Stroke Center, describes this approach as telemedicine.
He and his colleagues studied the use of a site-independent telemedicine system while being used to provide remote consultation, leading to treatment decisions about stroke patients.
The researchers say that their main objective was to determine whether such an approach could allow doctors to make good treatment decisions, and better decisions than telephone consultations, when evaluating stroke patients across distant sites.
The results of the STRokE DOC trial, based on 222 patients cases, showed that telemedicine evaluation actually led to better decision-making than telephone consultations in the care of those patients.
A research article in the journal Lancet Neurology says that STRokE DOC connects stroke experts located at a "hub" site to the patient at a remote but connected "spoke" site via the Internet.
The article adds that the audio/video teleconsultation system allows the stroke expert real-time visual and audio access to the patient, medical team and medical data at the remote site.
"We assumed that telemedicine was a good idea, but it hadn't been scientifically tested until now. Using STRokE DOC, our stroke team physicians were able to evaluate the patient and help make the correct decision about treatment over 98 percent of the time, compared to only 82 percent of the time when doing a telephone consultation to a remote site," said Meyer, who is also associate professor of neurosciences at the UCSD School of Medicine.
UC San Diego stroke team doctors can access the telemedicine system from any location with an Internet connection, enabling them to rapidly connect with an emergency medicine practitioner, the patient and perhaps their family members at the "spoke".
The system not only allows the specialists to view physical signs of a possible stroke in order to assess the patient's condition, but also to speak to the patient, family members, nurses and attending physicians, as well as directly review CT scan images of the patient's brain.
Patients and their families can see, hear, and communicate directly with the stroke expert.
"When a person suffers a stroke, time is of the essence," Meyer said, adding that waiting too long to give the drug can result in bleeding in the brain, or even death.
"If you make a poor decision using a telephone consultation, you potentially put the patient at risk for a poor outcome. The question we set out to ask with this five-year study was, 'did we make the right decision?' The answer was overwhelmingly, yes," Meyer added.
He believes that the proof that telemedicine results in better treatment decisions than telephone consultations may lead to some immediate changes in how stroke patients in remote areas are evaluated and treated.
"Rural physicians can now provide much needed specialty care to their patients via telemedicine. This is welcome news for rural healthcare providers in the U.S.," said Dr. George Rodriguez of El Centro Regional Medical Center in California, a rural community partner with UC San Diego in its STRokE DOC program and a participating spoke hospital in the clinical trial.
The UC San Diego researchers say that the next step is a study to evaluate the long-term health outcomes of patients.
"What this study tells us is that we need a bigger trial to determine the difference - if any - in clinical outcomes for these patients," they say.
The reliability of telemedicine had already been established, as reported in the journal Neurology in 2005, where the UC San Diego team studied Internet-based remote video evaluations of acute stroke patients.
