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.

The role of value-based payment in promoting innovation to address social risks: a cross-sectional study of social risk screening by US physicians.
The authors studied the conditions under which value-based payment will encourage health care providers to innovate to address upstream social risks. Their results indicated that implementation of social risk screening was not associated with overall exposure to value-based payment for physician practices. They recommended expanding social risk screening in order to reduce the level of innovative capacity required.

Comparison of effectiveness and cost for different HIV screening strategies implemented at large urban medical centre in the United States.
This analysis compared the effectiveness and cost of three HIV testing strategies in a high HIV burden area in the U.S. in identifying new HIV infections. The investigators performed a cost analysis comparing three HIV testing strategies in Chicago: (1) routine screening (RS) in an inpatient and outpatient setting, (2) modified partner services (MPS) among networks of the recently HIV infected and diagnosed, and (3) a respondent drive sampling (RDS)-based social network (SN) approach targeting young African-American men who have sex with men.

Is it time for ACOs to start tackling the high costs of surgery?
This article discusses an article appearing in the same issue revisiting the impact of Medicare Shared Savings Program (MSSP) accountable care organizations (ACOs) on surgery expenditures. The author suggests that, in order to engage even more surgeons, it is likely that MSSP ACOs will have to work with surgeons in the various Medicare bundled payment programs for surgery. He concludes that the next stage is to examine how these different programs can work together to produce even more savings in surgical care.

Achieving the Quadruple Aim to deliver value-based allergy care in an ever-evolving health care system.
Researchers sought to define the concept of value-based care in allergy, and to review challenges and opportunities in value-based health care delivery for allergists and immunologists. A review of articles describing practice variation, health care financing and reimbursement, shared decision-making, cost-effective health care delivery, patient-reported outcome measures, social determinants of health, and screening was conducted. The researchers concluded that, as health care systems continue to evolve, allergists and immunologists will play a key role in optimizing value by translating emerging evidence into practice and communicating novel approaches to prevent and treat allergic diseases.

Can vertically integrated health systems provide greater value: the case of hospitals under the comprehensive care for joint replacement model?
The authors sought to assess whether system providers perform better than non-system providers under an alternative payment model that incentivizes high-quality, cost-efficient care. Using CMS data linked to AHRQ’s Compendium of US Health Systems, along with secondary sources, they found that when operating under alternative payment model incentives, vertical integration may enable hospitals to lower costs with similar quality scores.

Kennedy G, Lewis VA, Kundu S, Mousqués J, Colla CH. Accountable care organizations and post-acute care: a focus on preferred SNF networks.
This study examined the relationship between accountable care organizations (ACOs) and skilled nursing facilities (SNFs) for patients who are discharged from a hospital into a SNF. A mixed-method design was used and survey data was examined from 366 respondents to the National Survey of ACOs along with 16 semi-structured interviews with ACOs who performed well on cost and quality measures. Over half of ACOs had no formal relationship with SNFs; however the majority of ACO interviewees had preferred SNF networks. These preferred networks are beginning to transform the ACO post-acute care landscape.

Too much surgery: overcoming barriers to deimplementation of low-value surgery.
The objectives of this surgical perspective are to discuss the unique aspects of surgical care delivery acting as barriers to de-implementation and to suggest potential strategies to reduce low-value surgery in the United States. Successful de-implementation of low-value surgery will depend on understanding why low-value procedures persist, leveraging quality collaboratives to monitor appropriateness, implementing clinical decision support systems, and developing incentives for de-implementation.

A comparison of international prenatal care guidelines for low-risk women to inform high-value care.
The authors compared U.S. to international prenatal care consensus guidelines for low-risk women to inform care delivery reforms. They found that U.S. and peer-country guidelines recommended similar prenatal education and psychosocial services for low-risk women; however, peer countries generally recommended fewer visits, longer intervals between visits, and less reliance on obstetrician-gynecologists for routine, low-risk prenatal care. They recommended that further investigation evaluate associations between recommended care and actual practice, as well as the effects of different components of prenatal care and delivery models on maternal-infant outcomes, patient-centeredness, and health care expenditures in the U.S.

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.

The potential economic value of a Zika vaccine for a woman of childbearing age.
The authors mapped the Zika vaccine and vaccination characteristic thresholds at which vaccination becomes cost effective, highly cost effective, and cost saving. They developed a Markov model to simulate a woman of childbearing age to follow the potential risk and clinical course of a Zika infection. They found that, in some cases, the vaccine was cost effective when the risk was as low as 0.015%, the cost was as high as $7,500, the efficacy was as low as 25%, and the duration of protection was 1 year. They concluded that the thresholds at which vaccination becomes cost effective and cost saving can provide targets for Zika vaccine development and implementation.

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.

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.

Do robotic surgical systems improve profit margins? A cross-sectional analysis of California hospitals.
The aim of this study was to examine the association between ownership of robotic surgical systems and hospital profit margins. Hospitals with robotic surgical systems tended to report more favorable profit margins. However, multilevel logistic regression showed that this relationship (an association, not causality) became only marginally significant after controlling for other hospital characteristics.

Relationship between race and the effect of fluids on long-term mortality after acute respiratory distress syndrome. secondary analysis of the National Heart, Lung, and Blood Institute Fluid and Catheter Treatment Trial.
Short-term follow-up in the Fluid and Catheter Treatment Trial (FACTT) suggested differential mortality by race with conservative fluid management, but no significant interaction. A post hoc analysis of FACTT and the Economic Analysis of Pulmonary Artery Catheters (EAPAC) study was performed. The researchers found that in their cohort, conservative fluid management may have improved 1-year mortality for non-Hispanic black patients with ARDS. However, they found no long-term benefit of conservative fluid management in white subjects.

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.

Reference pricing changes the 'choice architecture' of health care for consumers.
This article summarizes reference pricing's impacts to date on patient choice, provider prices, surgical complications, and employer spending and estimates its potential impacts if expanded to more services and a broader population. Reference pricing induces consumers to select lower-price alternatives for all of the forms of care studied, leading to significant reductions in prices paid and spending incurred by insurers and employers.
