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.

Association of practice-level social and medical risk with performance in the Medicare physician value-based payment modifier program.
The objective of this cross-sectional observational study was to compare performance in the Physician Value-Based Payment Modifier (PVBM) Program by practice characteristics. The investigators found that during the first year of the Medicare Physician Value-Based Payment Modifier Program, physician practices that served more socially high-risk patients had lower quality and lower costs, and practices that served more medically high-risk patients had lower quality and higher costs.

Price variations and their trends in U.S. hospitals.
This study tracked trends in prices paid to hospitals by commercial insurers over the period 2008 to 2014 using private sector claims data that contain actual payments. It contrasted these with trends in the CMS published charges. Results indicated that variation in actual commercially-transacted prices is substantially lower than variation in published charges.

Variation in payment rates under Medicare's Inpatient Prospective Payment System.
The researchers measured variation in payment rates under Medicare's Inpatient Prospective Payment System (IPPS) and identified the main payment adjustments that drive variation. In 2013, Medicare paid for acute inpatient discharges at a rate 31 percent above the IPPS base. For the top 10 percent of discharges, the mean rate was double the IPPS base. Variations were driven by adjustments for medical education and care to low-income populations.

Effects of payment reform in more versus less competitive markets.
In this paper, the authors exploit a major payment reform for home health care to examine whether reductions in reimbursement lead to differential changes in treatment intensity and provider costs depending on the level of competition in a market. Using Medicare claims, they find that while providers in more competitive markets had higher average costs in the pre-reform period, these markets experienced larger proportional reductions in treatment intensity and costs after the reform relative to less competitive markets..
