Assessment of prevalence and cost of care cascades after routine testing during the Medicare annual wellness visit.
This observational cohort study looked at the prevalence and cost of care cascades after routine tests considered low value in fee-for-service Medicare patients from January 2013 through March 2015 who had gone for an annual wellness visit (AWV). Among the 75,275 AWV recipients identified, 18.6% received at least 1 low-value test including an ECG, urinalysis, or thyrotropin tests. Patients who were younger, White, and lived in urban, high-income areas were most likely to receive those tests. The cost-cascade was considered notable but of modest cost.

Association between specialist compensation and Accountable Care Organization performance.
This study’s objective was to determine whether Medicare Shared Savings Program Accountable Care Organizations (ACOs) using cost reduction measures in specialist compensation demonstrated better performance. National cross-sectional survey data on ACOs from 2013-2015 was linked to public-use data on ACO performance from 2014-2016. Out of 160 ACOs surveys, 26% reported using cost reduction measures to help determine specialist compensation. However, these ACOs did not have savings in the short term.

Biosimilar uptake in Medicare Part B varied across hospital outpatient departments and physician practices: the case of filgrastim.
The purpose of this study was to examine the uptake of filgrastim-sndz (Zarxio), the first biosimilar to launch in the United States, in the Medicare Part B fee-for-service program from its launch in September 2015 to December 2017 and compare characteristics of patients and facilities that used filgrastim-sndz or originator filgrastim (Neupogen). The investigators concluded that uptake of biosimilar filgrastim in the Medicare Part B program occurred despite multiple challenges to the adoption of biosimilars in the US market, suggesting that substantial potential savings could be generated by improving biosimilar uptake.

Low-value care and clinician engagement in a large Medicare shared savings program ACO: a survey of frontline clinicians.
The purpose of this study was to assess Accountable Care Organization (ACO) engagement of clinicians and whether engagement was associated with clinicians' reported difficulty implementing recommendations against low-value care. Participants included 1289 clinicians in the Physician Organization of Michigan ACO. Results showed that clinicians participating in a large Medicare ACO were broadly unaware of and unengaged with ACO objectives and activities. Whether low clinician engagement limits ACO efforts to reduce low-value care warrants further longitudinal study.

Measuring low-value care in Medicare.
To study health care overuse, this study developed claims-based measures of low-value services ranging from low-value cancer screening and preoperative testing to low-value surgical procedures. Services detected by a limited number of measures of low-value care constituted modest proportions of overall spending, but affected substantial proportions of Medicare beneficiaries and may reflect overuse.

A simple change to the Medicare Part D low-income subsidy program could save $5 billion.
The authors used an intelligent reassignment algorithm and 2008-09 Medicare Part D drug use and spending data to match enrollees to available Part D plans according to their medication needs. They found that such a reassignment approach, compared to the current approach, could have saved the federal government over $5 billion in 2009.

Physician and patient and caregiver health attitudes and their effect on Medicare resource allocation for patients with advanced cancer.
The investigators sought to determine how baseline attitudes toward quality vs quantity of life affect end-of-life resource allocation. They found that, compared with patients and caregivers, otolaryngology-head and neck surgery (OHNS) physician allocations differed significantly in all 15 benefit categories except home care. They concluded that understanding the effect of baseline attitudes is important for effective end-of-life discussions.

Effects of Medicare payment reform: evidence from the home health interim and prospective payment systems.
The researchers contrasted the effects of two Medicare payment reforms for home health agencies: the interim payment system (IPS) and the prospective payment system (PPS). The 1997 IPS reform lowered payments for both fee-for-service and episode-based care, as predicted by their conceptual model. The PPS in 2000 raised average but lowered marginal payment.
