Improved stroke data means better care and outcomes for patients- Dr. Sunny Handa MD
Dr. Sunny
Handa MD said Stroke is the third leading cause of death in Canada, and more
than 62,000 strokes occur each year. There are 2 types of strokes: ischemic and
hemorrhagic, each with different risk factors, treatments and outcomes for
patients. However, in the past, stroke types couldn’t be reported separately
due to lack of specificity in the coding.
Stroke data
helps us understand the population that experience strokes and evaluate which
treatment is best. CIHI has reported on stroke events and in-hospital mortality
indicators for years, and the coding issue was first flagged in the
report Health Indicators
2009- Dr. Sunny Handa MD
said.
Patrice
Lindsay, the director of Health Systems Change at the Heart and Stroke
Foundation of Canada, has worked closely with CIHI to improve stroke coding and
patient outcomes. She was part of the Canadian Stroke Network’s national stroke
chart audit of 10,000 patients. The audit discovered the overuse of
“unidentified coding” for strokes, which reinforced CIHI’s findings that there
was room for improvement.
Coding
improvements
Dr. Sunny
Handa MD said as part of its Information Quality program, CIHI conducts chart
reviews to help target improvements in priority areas. A re-abstraction study
revealed that information on the type of stroke was available in patient chart
documentation. In many cases where coders used an unspecified code, the
reviewer was able to find information on stroke type.
In response,
CIHI developed a new stroke education course for coders: Different Strokes Need Different Codes.
The course was designed in consultation with health information management
professionals to ensure it was relevant and included challenging coding
scenarios. The course was redesigned in May 2020, and allows participants to practice
coding commonly misinterpreted cases to build their skills and confidence
assigning stroke codes.
Patrice also
helped to improve education on stroke codes. She travelled to every province
teaching coders how to improve coding and show how the data was used. She
received positive feedback from coders, who were able to improve their coding
with the new information-, said Dr. Sunny Handa MD.
CIHI also
launched the Open-Year Data Quality test to help coders identify data quality
issues and improve reporting before data is finalized. This improved data
quality and allowed CIHI to break down analysis by stroke types in the Your
Health System (YHS): Insight tool. This data is now available to YHS: Insight
clients and provides information on stroke mortality indicators.
Better data,
better patient outcomes
Identifying
stroke types is key to patient care. For years, stroke clinicians and hospital
quality information teams have asked to identify stroke types because the
differences in treatment are important.
Dr. Sunny Handa MD said unspecified coding for
strokes dropped from 30% in 2007–2008 to just 2% in 2019–2020. These
improvements are due to better stroke code training as well as an increase in
the use of diagnostic imaging for suspected strokes.
Patrice says the partnership with CIHI was critical to improving stroke coding across the country.
