Different hospitals produce different results on different procedures. Only, patients don’t know that data, making choosing a surgeon a high-stakes guessing game. Stefan Larsson looks at what happens when doctors measure and share their outcomes on hip replacement surgery, for example, to see which techniques are proving the most effective. Could health care get better -- and cheaper -- if doctors learn from each other in a continuous feedback loop?

A paradigm shift: Swedish doctors' collaboration on hip surgery techniques significantly improved patient outcomes and reduced costs.

Raising US healthcare quality to OECD average could save $500 billion annually, proving high-quality care reduces overall expenses.

Surgeons' varied hip surgery techniques reveal dramatic quality gaps; sharing outcomes can spark global healthcare improvements.
