Yelp star ratings on health care facilities may reveal county-level death rate disparities

A one-star disparity on health care facility Yelp reviews could indicate a 60-death-peryear difference between some United States counties where those facilities are located, according to researchers at the Penn Medicine Center for Digital Health. Their study shows that counties holding health care facilities with the greatest share of 1-star Yelp reviews had the highest death rates, and a difference of just one point—roughly one star—between counties’ average scores could indicate a mortality rate that is better or worse by dozens of lives. This work was published today in the JAMA Network Open.
