Minnesota's hospitals had an increase in the number of preventable errors in 2017, according to a new report released in late February.

The state was a pioneer in requiring hospitals to report data on preventable errors -- also known as adverse events -- starting in 2005. There are now 32 categories, including medication errors, foreign objects left in a body during surgery, serious pressure ulcers, and operating on the wrong body part.

Some categories have changed over the years -- for example, before 2010, hospitals reported only patient falls that led to death, but now they also report those that cause serious injuries.
