Case study 2: Stroke

Case study 2: Stroke

Stroke is a significant public health issue because it poses a significant burden on patients and their families, the health system and aged–care services. However, data which informs the planning of health services for stroke survivors is limited because we don’t fully understand if the risk of having a stroke increases or decreases after a patient has a mini-stroke. This study investigated whether people who presented to Victorian hospitals after having a mini-stroke were at risk of having a stroke caused by a blocked artery. The researchers found that over the last 10 years, there has been an overall decline in the number of reported mini-strokes in Victoria (Australia) and a decline in the risk of a stroke after a reported mini-stroke.
