Covering vascular surgery? Watch for selection bias in this database

If you cover medical research related to vascular procedures and conditions, you’ve likely come across studies using data from the Society for Vascular Surgery Vascular Quality Initiative (SVS VQI).

As a database designed to improve patient safety, the SVS VQI can be very useful for analyzing outcomes and associated variable for 12 major vascular procedures as long as researchers (and journalists) are aware of the limitations of the data set. Continue reading

Researchers identify new genetic stroke risk factors

One of the largest analyses of stroke factors ever conducted is providing scientists with new clues to identify stroke mechanisms and potential treatments. Researchers have identified 22 new genetic risk factors, tripling the number of gene regions known to affect stroke risk.

By mining an enormous trove of data, a team of international researchers obtained critical new insights into the specific genes, molecular pathways, and cell and tissue types through which the new genetic risk factors cause a stroke. Continue reading
