And absolutely no mention of doing anything to stop the
neuronal cascade of death. Solve that and you can congratulate yourself, until then you have very little to be pleased about.

Stroke care networks save lives and reduce the need for long-term
care, a study of one of the largest and longest operating networks
confirmed.
In an integrated system of stroke care delivery in
Ontario mortality rates 30 days after hemorrhagic stroke decreased from
38.3% to 34.4% after the networks were fully implemented (
P<0.001) and discharge to a long-term care or chronic care facility dropped from 16.9% to 14.8% (
P<0.001),
reported Moira Kapral, MD, of the University of Toronto Institute for
Clinical Evaluative Sciences, and colleagues in
CMAJ.
The
10-year study included data on 243,287 patient visits to emergency
departments (ED) and 163,198 hospital admissions for acute stroke or
transient ischemic attack before and after 2005, when the stroke care
network became fully operational in Ontario.
The networks
are designed to integrate the delivery of stroke treatment across
regions to optimize the chances that patients will receive timely,
evidence-based therapies even if they don't live near a designated
stroke center.
"After the stroke network was introduced there were clear improvements in the quality of stroke care," Kapral told
MedPage Today.
"More patients were treated with optimal stroke care interventions,
such as thrombolysis, including clot-busting drugs, and stroke-unit
care."
Kapral's group used population-based provincial
administrative databases to identify all ED visits and hospital
admissions for acute stroke and transient ischemic attack from 2001 to
2010.
They assessed the effect of the full implementation of the
Ontario Stroke System in 2005 on the proportion of patients who received
care at stroke centers, and on rates of discharge to long-term care
facilities and 30-day mortality after stroke.
The proportion of
patients who received care at either a regional or district stroke
center increased from 40% before 2005 to 46.5% after full implementation
of the system (
P<0.001). The median time from stroke presentation to carotid revascularization decreased from 50 to 22 days (
P<0 .001="" p="">Piecewise
regression analysis showed a gradual increase in the rate of care at
stroke centers before 2005, followed by a significant upward shift in
rates in 2005.
And significant increases were seen between 2002 and 2009 in rates for the following (
P<0.001 for all):
- Thrombolytic therapy use: 10% to 27%
- Neuroimaging: 77% to 93%
- Carotid imaging: 44% to 68%
- Care in a stroke unit: 3% to 24%
- Dysphagia screening: 47% to 57%
- Antithrombotic therapy: 80% to 94%
By
far the biggest improvements were seen at regional and district stroke
centers, with little or no change evident at nondesignated centers, the
authors reported.
The authors cautioned that "although we observed
an increase in the proportion of patients seen at designated stroke
centers over the study period, the absolute magnitude of the increase
was modest, with more than half of the population receiving care at
nondesignated centers even 5 years following the full implementation of
the stroke system."
They suggested that this was the result of the
system being designed mostly to facilitate the transfer, or bypass, of
those patients most likely to be good candidates for thrombolytic
therapy or neurosurgical interventions.
Nonetheless, the decreases
would be expected to result in about 200 fewer stroke-related deaths
and 300 fewer patients requiring long-term care or chronic care
annually, they pointed out.
The researchers conceded that
significant regional variations in care persist, and they acknowledged
that Ontario's large and geographically diverse territory has made the
implementation of an integrated stroke care network a challenge.
Kapral
said increased utilization of telemedicine and other efforts to provide
evidence-based therapies to patients not treated at designated stroke
centers should improve patient outcomes.
The Ontario Telestroke
Program has provided neurologist consultations for stroke patients
treated at regional hospitals without stroke centers over the last
decade and 30% received thrombolytic treatments.
"Despite our best
efforts, there will always be patients who just don't live close enough
to a stroke center to be treated at one," she said. "That is why
networks are especially important in rural and remote areas."
The
study had some limitations. The authors focused on hospital-based
processes of care and outcomes and did not have data on longer-term
outcomes such as functional status, quality of life, or after-stroke
care. Also, the piecewise regression analyses did not account for the
potential effects of concurrent interventions.
Still, they
concluded that the findings provide stroke support for the ongoing
development and implementation of networks to coordinate the delivery of
stroke care, and that "future research should focus on identifying the
specific components of such systems that are most likely to account for
improvements in outcomes."
