Extending specialized care through
telemedicine may improve stroke outcomes
Stroke patients have significantly better chances of
surviving and living independently when they receive specialized stroke care in
community hospitals that have telecommunication support from major stroke centers,
according to a study in Stroke: Journal of the American Heart Association.
At 12 and 30 months after stroke, patients treated at
hospitals with specialized stroke units had a significantly lower rate of "death
and dependency" than did patients who received care at hospitals without stroke
units. Dependency was defined as disability or need for institutional care.
The findings extend the benefits of specialized stroke
care with telemedicine support initially observed three months after stroke.
"What we see is that not only does the quality of care
improve very significantly, but also the subsequent prognosis of the patients,"
said Heinrich Audebert, M.D., a stroke specialist at Charite Hospital in Berlin,
Germany. "These effects are also quite stable. We can see the effects after one
and two years and, at least in our trial, after two and a half years."
Most community hospitals don't have dedicated stroke
units because of a shortage of experienced physicians and lack of access to stroke-related
clinical expertise at major medical centers. Rural areas, in particular, often
have inadequate resources to provide specialized stroke care.
The advent of telemedicine has provided an opportunity
to expand the reach of specialized acute care services to virtually any hospital,
regardless of location. Telemedicine involves using communication links to transmit
and receive data and information at remote locations.
In the Telemedical Project for Integrative Stroke Care
(TEMPiS), researchers examined the feasibility and potential value of extending
specialized stroke care to a large area of the Bavarian region of southeastern
Germany. TEMPiS represented a collaboration between two academic stroke centers
and community hospitals in Bavaria. Key components of the program included:
- Establishing stroke units at the community hospitals, including forming multidisciplinary
stroke teams to provide care;
- Installing monitoring equipment and facilities;
- Training and educating members of the stroke team, including continuous bedside
teaching by specialist physicians, nurses and therapists;
- Implementing standard treatment protocols; and
- Twenty-four-hour telemedicine consultation provided by the academic stroke
centers.
Researchers compared outcomes among stroke patients treated
at five TEMPiS hospitals with patient outcomes at five non-TEMPiS hospitals in
the same geographic region. The study included 3,060 stroke patients, 1,938 treated
at TEMPiS hospitals and 1,122 treated at other hospitals. Initial results showed
that specialized stroke care with telemedicine support led to better outcomes
at three months, specifically a significantly lower rate of the composite endpoint
of death and dependency.
The improvement was associated with practices indicative
of high-quality stroke care: rapid brain imaging, the frequency with which patients
received clot-dissolving drugs, assessment of stroke-related swallowing disorders,
and early initiation of stroke rehabilitation.
Audebert and colleagues reported on participants for
12 months and 30 months. Consistent with the three-month results, longer follow-up
showed a statistically not significant trend towards a better outcome of the combined
outcome of death and institutional care.
However, patients treated at the TEMPiS hospitals had
a statistically significant 35 percent lower probability of death and dependency
at 12 months and almost a 20 percent reduced probability for this poor outcome
at 30 months compared with non-TEMPiS patients.
Audebert said a hospital would have to invest about $130,000
(confirmed by author) to set up a specialized stroke unit, including construction
and equipment costs. There are also additional costs for augmented nursing and
therapist staff in the community hospitals and personal costs for quality management
and teleconsultation service in the Stroke Centers. However, these costs are obviously
recouped over time by savings related to shorter hospitalizations and less disability.
