In a new study with implications for state and federal efforts to reform payments to doctors and hospitals to encourage greater coordination of care, Harvard Medical School researchers found that a global payment system underway in Massachusetts lowered medical spending while improving the quality of patient care relative to the traditional fee-for-service system.
The study, published in the New England Journal of Medicine, examined the Alternative Quality Contract (AQC), which was first introduced by Blue Cross Blue Shield of Massachusetts (BCBSMA) in 2009 and now includes more than a third of the insurer's provider network.
Among the study's findings:
"The finding of reduced spending, together with improved quality in year-one of the contract is significant," says senior author Dr. Michael Chernew, Harvard Medical School. "For policymakers contemplating improved payment models for US health care, reducing medical spending while improving quality and outcomes is the Holy Grail. While much remains to be seen over the next years of these AQC contracts and as the model expands to other providers, these early results provide reason for optimism."
Chernew noted that changes in referral patterns like the kind accomplished in the AQC's first year can subsequently affect pricing in the health care market, as high-price facilities feel pressure from decreased volume. He also noted that the significance of the changes in physician thinking and behavior that are required to accomplish such changes in practice should not be understated.
Background on study:
In 2009, Blue Cross Blue Shield of Massachusetts began paying seven Massachusetts provider groups differently under a contracting model called the "Alternative Quality Contract" (AQC). This model is characterized by global payment, whereby provider groups received a budget (defined for five years) to take care of their BCBSMA patients, rather than being paid separately for each service (fee-for-service). In addition to the global budget, groups were eligible for pay-for-performance bonuses, which rewarded providers for meeting certain quality targets. Provider groups in the AQC system assume accountability for spending, similar to Accountable Care Organizations (ACOs). This study analyzed the effect of this intervention on health care quality and spending. Harvard Medical School researchers analyzed 2006-2009 claims for enrollees whose primary care physicians were in the AQC, compared with enrollees not in the AQC.
