Aquilion Clinical Case Study | Kaleida Health Stroke Care Center at the Gates Vascular Institute Acute Stroke Study—Phase Three
Advancing stroke care leveraging advanced imaging technology that improves patient outcomes and lower costs.
Seventy-five percent of all strokes that occur within the United States happen to people over the age of 65. With the aging of the baby boomer generation, it is anticipated that 20 percent of the U.S. population will be over the age of 65 by 2030. That translates to 70 million Americans who will be on Medicare by that year.
Canon Medical Systems partnered with Kaleida Health’s Stroke Care Center (SCC) at the Gates Vascular Institute, formerly Kaleida Health’s Stroke Center at Millard Fillmore Gates Circle Hospital, to conduct a multi-phase study analyzing stroke patient outcomes using Canon Medical Systems' Aquilion™ ONE CT system during diagnosis. The results demonstrate that a multidisciplinary, collaborative approach to patient care combined with the latest in imaging technology not only improves patient outcomes but also the bottom line.

Acute Stroke Study
Kaleida Health’s Stroke Care Center at the Gates Vascular Institute completed a three-phase, non-controlled study analyzing the patient and fiscal benefits of using Canon Medical Systems' Aquilion™ ONE CT system for diagnosing acute stroke.
RESULTS: Contained costs while delivering high-quality, effective patient care
$5.4 million annualized savings over four years
Full-day reduction in average patient length of stay
(ICD-9-CM 434.91: Unspecified Cerebral Artery Occlusion with Cerebral Infarction)
100% reduction in patients discharging to intermediate care facility
(ICD-9-CM 435.9: Unspecified Transient Cerebral Ischemia)
67% improvement in patients discharging to home
(ICD-9-CM 434.11: Cerebral Embolism with Cerebral Infarction)
19% reduction in patients discharging to rehab
(ICD-9-CM 434.91: Unspecified Cerebral Artery Occlusion with Cerebral Infarction)
Inpatient data sets from July to September 2007, prior to the Aquilion ONE installation, were compared with data sets from July to September 2009 (phase one), July to September 2010 (phase two), and from July to September 2011 and July to September 2012 (phase three), which utilized the Aquilion ONE, and concerned the top three discharging ICD-9-CM codes. Full data sets and study methodology available.
Canon Medical Systems' Aquilion ONE—Changing Clinical Pathways
The introduction of Canon Medical Systems' Aquilion ONE dynamic volume CT system changed the scope of cerebral perfusion analysis by enabling dynamic imaging of the entire brain and the ability to reduce diagnosis time from hours or days to minutes.
By pairing whole brain imaging with the Singular Value Decomposition Plus (SVD+) delay-insensitive perfusion algorithm, the Aquilion ONE produces the most advanced CT perfusion imaging in the industry.
Diagnosing acute stroke at gates stroke center with 320-detector row CT imaging.
The SCC reviewed the patient diagnostic workup for stroke patients and analyzed the imaging procedures utilized during the acute inpatient episode of care, focusing on the changes in the diagnostic work-up, inpatient length of stay and discharging disposition since acquiring the Aquilion ONE.
After the Aquilion ONE was used for diagnostic acquisition, the top three discharging ICD-9-CM codes were identified. The diagnostic patient work-ups were compared during these four time periods and identified significant differences of how acute stroke patients were diagnosed.
Retrospective Diagnostic
Work-up 2007
- Pre-MRI screening
- X-ray imaging
- Limited brain MRI
- MR perfusion
- MRA of the head and neck
Prospective Diagnostic
Work-up 2009
- Non-contrast head CT
- CT perfusion
- CTA head and neck
- MRI brain non-contrast
Combining a multidisciplinary approach with innovative technology.
During this time period, the SCC also made significant shifts in other aspects of patient care, further contributing to improved clinical outcomes. Following the relocation of the SCC from Millard Fillmore Gates Circle Hospital to the Gates Vascular Institute, the facility consolidated its vascular services and repositioned its Aquilion ONE CT systems adjacent to areas of high need: the emergency department and catheterization lab.
Bringing these benefits to other healthcare facilities
The SCC is an impressive example of how an exceptional multidisciplinary team with comprehensive education and community outreach can use innovative imaging technology to improve financial performance as the federal government implements new, shared-risk, delivery models of patient care. Healthcare facilities with dedicated stroke programs can experience the significant cost savings achieved through reduced length of stay, reduction in outpatient services, reduced complications, and lower recurrence of readmission.
