Physician Consolidation and the Spread of Accountable Care Organizations

Research Brief
Nov. 4, 2019

Accountable Care Organizations (ACOs) are groups of physicians and hospitals that jointly contract to care for a patient population. ACO contracts incentivize coordination of care across providers. This can lead to greater consolidation of physician practices, which can in turn generate higher costs and lower quality. Given this, the study asks, as ACOs enter health care markets, do physician practices grow larger?

Abstract [from journal]

Importance:  An increasing number of hospitals have participated in Medicare’s bundled payment and accountable care organization (ACO) programs. Although participation in bundled payments has been associated with savings for lower-extremity joint replacement (LEJR) surgery, simultaneous participation in ACOs may be associated with different outcomes given the prevalence of LEJR among patients receiving care at ACO participant organizations and potential overlap in care redesign strategies adopted under the 2 payment models.

The Tension Between Care Coordination and Conflicts of Interest

Feb. 6, 2019

Should providers participating in accountable care organizations (ACOs) be exempt from existing regulations that prevent financial conflicts of interest in physician referrals? On the one hand, these regulations, collectively known as the Stark Law, can impede efforts to coordinate care across providers and facilities. On the other hand, ACOs and other alternative payment and delivery models do not necessarily obviate the need for regulations that prohibit physician kickbacks or self-referrals.

Value Based Payment: Is This Time Actually Different?

Mar. 8, 2018

Practice transformation and payment reform are defining features of contemporary health policy debates. The story goes like this: new provider organizations, such as Accountable Care Organizations (ACOs) are transforming care delivery from fragmented and volume driven to integrated and optimized for quality; meanwhile, innovative payment models, such as bundled payments and risk-based contracting, herald a national transition from fee-for-service (FFS) to value-based payments.

The “value” of value in gynecologic oncology practice in the United States: Society of Gynecologic Oncology evidence-based review and recommendations

Jun. 20, 2017

David E. Cohn, Emily Ko, Larissa A. Meyer, Jason D. Wright, Sarah M. Temkin, Jonathan Foote, Nathaniel L. Jones, Laura J. Havrilesky

In Gynecologic Oncology, David Cohn and colleagues, including Emily Ko, examine trends in gynecologic oncology health care expenditures, and assess how costs may be affected by new models of health care delivery and payment. The authors conduct a review on behalf of the Society of Gynecologic Oncology, and discuss the financial burden of increasing co-payments for cancer patients. They emphasize the need for gynecologic oncology practitioners to prepare for new models of cancer care delivery, such as Oncology Patient-Centered Medical Homes (OCPHM), as well as newer pay for...
