Payer type and low-value care: comparing Choosing Wisely services across commercial and Medicare populations.
This study compared low-value health service use among commercially insured and Medicare populations and explored the influence of payer type on the provision of low-value care. In measuring use of seven Choosing Wisely-identified low-value services, it concluded that low-value care appears driven by factors unrelated to payer type or anticipated reimbursement.

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.

Recent health care use and Medicaid entry of Medicare beneficiaries.
The purpose of this study was to examine the relationship between Medicaid entry and recent health care use among Medicare beneficiaries. Although recent health care use predicted greater likelihood of Medicaid entry, half of new Medicaid participants used no hospital or nursing home care during the study period.

Hospice enrollment in patients with advanced heart failure decreases acute medical service utilization.
Patients with advanced heart failure (HF) enroll in hospice at low rates, and data on their acute medical service utilization after hospice enrollment is limited. This descriptive analysis of Medicare fee-for-service beneficiaries found that home health care Medicare beneficiaries with advanced HF who enrolled in hospice had lower acute medical service utilization after their enrollment.

The effects of the transition from Medicaid to Medicare on health care use for adults with mental illness.
The researchers estimated the effect of dual coverage after Medicaid enrollment during the required waiting period among adults with serious mental illness on health care use, overall and related to mental health and substance use disorders. They found that after 12 months of dual coverage, the probability of outpatient care use increased in both states from 4 percent to 9 percent.

Limited use of surveillance imaging following nephrectomy for renal cell carcinoma.
The researchers evaluated the utilization of follow-up imaging after nephrectomy for renal cell carcinoma (RCC) in nationally representative data. Using Surveillance, Epidemiology, End Results (SEER) data, they found that, in the Medicare population, surveillance imaging is performed in a limited number of patients following nephrectomy for RCC but that increasing tumor stage is predictive of both increased chest and abdominal imaging surveillance.

Hospice enrollment, local hospice utilization patterns, and rehospitalization in Medicare patients.
The study objective was to examine the association between hospice enrollment, local hospice utilization patterns and 30-day rehospitalization in Medicare patients. It found that area-level hospice utilization is inversely proportional to rehospitalization rates. This relationship is not fully explained by direct hospice enrollment, and may reflect a spillover effect of the benefits of hospice extending to nonenrollees.

Projected clinical, resource use, and fiscal impacts of implementing low-dose computed tomography lung cancer screening in Medicare.
The Centers for Medicare and Medicaid Services (CMS) recently issued a national coverage determination that provides reimbursement for low-dose computed tomography (CT) lung cancer screening for enrollees age 55 to 77 years. This study’s simulation model projected that over 5 years, that low-dose CT screening will result in 10.7 million more low-dose CT scans, 52,000 more lung cancers detected, and increased overall expenditure of $6.8 billion.

Bariatric surgery in minority patients before and after implementation of a centers of excellence program.
This study compared rates of bariatric surgery for minority Medicare vs. non-Medicare patients before and after the 2006 implementation of a national coverage decision (NCD) restricting Medicare patients to centers of excellence for bariatric surgery. It found that the proportion of nonwhite Medicare patients receiving this procedure dropped from 27.5 percent before the NCD to 25.9 percent afterwards.

Medicare and commercial inpatient resource use: impact of hospital competition.
The authors examined the influence of hospital competition on small-area inpatient resource use by payer. Using HCUP data, they found that policies or incentives that promote or encourage competition in less competitive markets may reduce variation in resource use for both Medicare and private payers.

Patterns of erythropoiesis-stimulating agent use among Medicare beneficiaries with myelodysplastic syndromes and consistency with clinical guidelines.
The researchers used SEER registries data to assess population-based patterns of erythropoiesis-stimulating agents (ESA) use relative to treatment guidelines. They found widespread use of ESA in Medicare beneficiaries with myelodysplastic syndromes.
