What role does efficiency play in understanding the relationship between cost and quality in physician organizations?
Previous studies demonstrate overuse of a narrow set of services, suggesting provider inefficiency, but existing studies neither quantify inefficiency more broadly nor assess its variation across physician organizations (POs). This study found that POs had substantial variation in efficiency, producing widely differing levels of quality for the same cost.

The nature of surgeon human capital depreciation.
The authors estimated how temporal breaks affect surgeons' performance of coronary artery bypass grafting (CABG). They found that a surgeon's additional day away from the operating room raised patients' inpatient mortality by up to 0.067 percentage points but reduced total hospitalization costs by up to 0.59 percentage points, and among emergent patients treated by high-volume providers, an additional day away raised mortality risk by 0.398 percentage points but reduced cost by up to 1.4 percentage points. They concluded that their results are consistent with the hypothesis that as temporal distance increases, surgeons are less likely to recognize and address life-threatening complications.
