ProPublica and the Houston Chronicle have a series of articles about one of the original ground breaking hospitals for heart transplants which now has one of the worst outcomes for transplant recipients in the country.
Heart Failure
Tracking the Decline of a Historic Heart Transplant Program
ProPublica and the Houston Chronicle are investigating troubles at Baylor St. Luke’s in Houston, an illustrious heart program that has recently had some of the worst outcomes in the country.

I like the ProPublica investigations be it how Walmart's rely on local police forces heavily for loss prevention and thus are a huge burden on small police forces, to how certain police forces enforce laws like jaywalking significantly more in African American neighborhoods, to how industry money reaches physicians. A lot of their reporting is data driven so they use available datasets like crime statistics, or residential property appraisals in Chicago to identify trends that show bias.
