Favorable risk selection in Medicare Advantage: trends in mortality and plan exits among nursing home beneficiaries.
This study uses mortality differences, nursing home utilization, and switch rates to assess whether the 2003 Medicare Modernization Act (MMA) successfully decreased risk selection from 2000 to 2012. The study found no decrease in the mortality difference or adjusted difference in nursing home use between plan beneficiaries pre- and post the MMA.

Implications of DRG classification in a bundled payment initiative for COPD.
The researchers hypothesized that patients included in a the Medicare Bundled Payments for Care Improvement (BPCI) initiative for chronic obstructive pulmonary disease (COPD) would have less severe illness and decreased hospital utilization compared with those excluded from the bundled payment initiative. They concluded that the use of DRGs to identify patients with COPD for inclusion in the BPCI initiative led to the exclusion of more than one-third of patients with acute exacerbations.

Long-term impact of a postdischarge community health worker intervention on health care costs in a safety-net system.
This study evaluated the impact of a patient navigator (PN) intervention on health system costs in the 180 days after discharge for high-risk patients in a safety-net system. Total costs per patient over the 180 days postindex discharge for those aged >/=60 years were significantly lower for PN patients compared to controls ($5,676 vs. $7,640); differences for patients aged <60 ($9,942 vs. $9,046) or for the entire cohort ($7,092 vs. $7,953) were not significant.

Patient-physician communication on medication cost during glaucoma visits.
The aim of this secondary analysis was to describe the frequency and nature of patient-physician communication regarding medication cost during glaucoma office visits. Most participants did not discuss medication cost during their glaucoma office visit. The majority of the subjects who discussed cost had mild disease severity (51 percent), took one glaucoma medication (63 percent), and had Medicare (49 percent) as well as a form of prescription insurance (78 percent).

Public and private payments for physician office visits.
Using data for 2014-15 from the Medical Expenditure Panel Survey to estimate standardized payments for nonelderly adults' physician office visits by type of insurance, researchers found that adults with public insurance, especially Medicaid, had substantially lower provider payments, out-of-pocket spending, and third-party payments than their peers with employer-sponsored or Marketplace insurance.

Rising use of observation care among the commercially insured may lead to total and out-of-pocket cost savings.
Using multipayer commercial claims for the period 2009-13, the investigators evaluated utilization and spending among patients admitted for six conditions that are commonly managed with either observation care or short-stay hospitalizations. In their study period, the use of observation care increased relative to that of short-stay hospitalizations. In addition, total and out-of-pocket spending were substantially lower for observation care, though both grew rapidly--and at rates much higher than spending in the inpatient setting--over the study period.

The alternative quality contract: impact on service use and spending for children with ADHD.
The authors used Blue Cross-Blue Shield of Massachusetts (BCBSMA) claims for 2006-2011 to compare youths enrolled in provider organizations participating in the alternative quality contract (AQC) with those not participating. They found that the AQC was associated with small increases in the probability of any outpatient visits and in the probability and number of medication management visits among children with attention-deficit hyperactivity disorder (ADHD). Further, spending did not change, and there was no evidence of reductions in service utilization or spending for children with ADHD in the first three years of AQC implementation.

The impact of state medical malpractice reform on individual-level health care expenditures.
This study aims to fill the evidence gap concerning the effect of different types of malpractice reform by examining the general population, not a subgroup or a specific health condition, and controlling for individual-level sociodemographic and health status. It found that only two of the 10 major state-level malpractice reforms had significant impacts on the growth of individual-level health expenditures.

The moral hazard effects of consumer responses to targeted cost-sharing.
This paper examines the effects of the reference pricing program implemented by the California Public Employees Retirement System (CalPERS) in 2012. The investigators found that the cost savings from the reference pricing program was about two to three times as large as the reduction from implementing a high-deductible health plan, while the accompanying consumer surplus reduction was much smaller under reference pricing.

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.

Depression, quality of life, and medical resource utilization in sickle cell disease.
Researchers performed an analytic epidemiologic prospective study to determine the prevalence of depression in adult patients with sickle cell disease and its association with health-related quality of life (HRQoL) and medical resource utilization. They found that depression was associated with worse physical and mental HRQoL scores and during the 6 months following diagnosis, mean total health care costs were significantly higher in depressed patients than in nondepressed patients.

Nationwide coverage and cost-sharing for PCSK9 inhibitors among Medicare Part D plans.
In this research letter the investigators analyzed the June 2016 Centers for Medicare and Medicaid Services Prescription Drug Plan Formulary, Pharmacy Network, and Pricing Information Files for all Part D plans (except special-needs plans that may have had specialized formularies) and out-of-pocket cost requirements for PCSK9is (alirocumab and evolocumab) averaged across all plans by counties and states. The authors asserted that their findings suggest a need to lower out-of pocket costs to ensure affordability of PCSK9is for Medicare beneficiaries covered by Part D.

Reducing young adults' health care spending through the ACA expansion of dependent coverage.
The researchers estimated health care expenditure trends among young adults ages 19-25 before and after the 2010 implementation of the Affordable Care Act (ACA) provision that extended eligibility for dependent private health insurance coverage. They found that increased health insurance enrollment as a consequence of the ACA provision for dependent coverage has successfully reduced spending and catastrophic expenditures, providing financial protections for young adults.

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.
