Effects of the ACA on Health Care Cost Containment

Issue Brief
Mar. 2, 2017

This brief reviews the evidence on how key ACA provisions have affected the growth of health care costs. Coverage expansions produced a predictable jump in health care spending, amidst a slowdown that began a decade ago. Although we have not returned to the double-digit increases of the past, the authors find little evidence that ACA cost containment provisions produced changes necessary to “bend the cost curve.” Cost control will likely play a prominent role in the next round of health reform and will be critical to sustaining coverage gains in the long term.

New Study Details Savings from Bundled Payments

Jan. 13, 2017

This is the way it is supposed to work. You develop policy and processes to drive innovation. You design and test innovative ideas in a small, efficient way. You learn and adapt. Successful innovation drives new policy. Rinse and repeat.

And this is the way it appears to have worked, in the case of Medicare bundled payment. Start small with a pilot. Expand in reach and scope if promising. Scale up if successful.

Evidence on the effects of bundled payment is more important than ever, while hospitals already in Medicare bundled payment programs need guidance in redesigning care. This observational study looks at whether bundled payment for joint replacement affected quality, hospital costs and post-acute care spending in a health system that was an early adopter of the model. Did the bundles save money, and if so, what produced those savings?

Comparing the contributions of acute and post acute care facility characteristics to outcomes after hospitalization for hip fracture

Jan. 2, 2017

Neuman, Mark D.; Silber, Jeffrey H.; Passarella, Molly R.; Werner, Rachel M.

In Medical Care, LDI Senior Fellows Mark Neuman, Jeffrey Silber and Rachel Werner and colleagues quantify the contribution of acute versus post acute care factors to survival and functional outcomes after hip fracture. This retrospective cohort study was conducted using Medicare data from previously ambulatory nursing home residents hospitalized for hip fracture between 2005 and 2009. The authors measured the associations of hospital and nursing home factors with functional and survival outcomes at 30 and 180 days among patients discharged to a nursing facility,...

The Anticipatory Effects of Medicare Part D on Drug Utilization

Dec. 1, 2016

Abby Alpert

In the Journal of Health Economics, Abby Alpert examines anticipation effects of Medicare Part D, which went into effect two years after it was signed into law. This potentially gave forward-looking individuals time to change their drug consumption behavior in anticipation of future subsidized drug coverage. This approach contrasts with prior studies of Part D, which do not take the possibility of behavioral responses to the announcement into consideration, thus...

A Synchronized Prescription Refill Program Improved Medication Adherence

Aug. 5, 2016

Jalpa A. Doshi, Raymond Lim, Pengxiang Li, Peinie P. Young, Victor F. Lawnicki, Joseph J. State, Andrea B. Troxel, and Kevin G. Volpp

In Health Affairs, Jalpa Doshi and colleagues, including Pengxiang Lee, Andrea Troxel and Kevin Volpp, evaluate whether renewing all medications at the same time from the same pharmacy improves adherence to medication regimens. Synchronizing medication refills is an increasingly popular strategy, but there has been little research regarding its effectiveness. The authors looked at a pilot refill synchronization program implemented by Humana, a large national insurer, and analyzed patients’ adherence before and after participation in the program, compared to a control group. The...

Accounting for Social Risk Factors in Medicare Payment: Third National Report

Jul. 19, 2016

How should social risk factors enter into Medicare’s value-based payments to hospitals? The answer goes beyond an arcane discussion of payment policy; it has a direct impact on hospital bottom lines and the quality of care provided to underserved communities.  A new report from the National Academies of Sciences, Engineering, and Medicine—the third in a series of five—lays out criteria and methods to account for social risk factors in Medicare payment.  

Impact of Medicare Advantage Prescription Drug Plan Star Ratings on Enrollment Before and After Implementation of Quality-Related Bonus Payments in 2012

Research Brief
Jun. 10, 2016

In PLOS ONE, LDI Senior Fellows Pengxiang Li and Jalpa Doshi examine the impact of the Medicare Advantage Presciption Drug Plan star ratings before and after 2012, when they became tied to bonus payments. Does an increase in a plan’s star rating have a direct impact on concurrent year plan enrollment? What’s the indirect impact (via bonus payments) of star ratings on subsequent year plan enrollment?

Detecting Potential Overbilling in Medicare Reimbursement via Hours Worked

Research Brief
Apr. 18, 2016

Overbilling for physician services under Medicare Part B has long been a concern, as some estimates show that fraudulent “upcoding” or “overcharging” might have cost the program tens of billions of dollars per year. Existing methods to detect the prevalence and financial cost of overbilling have various limitations, so the authors developed a novel approach: create estimates of actual hours worked as implied by the medical service codes that providers submit to Medicare. In an NBER Working Paper, LDI Senior Fellow Hanming Fang and co-author Qing Gong examine whether this method can generate a quicker and more robust estimation of overbilling across medical specialties and geographic areas.
