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.

Senior services in US hospitals and readmission risk in the Medicare population.
The purpose of this study was to determine whether hospitals' Senior Care Services Scale (SCSS) scores were associated with risk of readmission among Medicare beneficiaries. The study concluded that senior services at the hospital-level represented a modifiable risk factor with important impact. Employing organization-level characteristics in readmission risk prediction tools should be expanded.

Does insurance status influence a patient's hospital charge?
The objective of this study was to determine whether hospitals charge patients differently based on their insurance status. It concluded that conditional on patient characteristics, length of stay, and expected intensity of resource utilization, patients with private insurance and patients with Medicare were charged more (before discounting) than their uninsured counterparts within the same hospital.

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.

Hospital contributions to variability in the use of ICUs among elderly Medicare recipients.
Hospitals vary widely in ICU admission rates across numerous medical diagnoses. In This retrospective cohort study examined the extent to which variability in ICU use is specific to individual diagnoses or is a function of the hospital, regardless of disease. The authors concluded that hospitals account for a significant proportion of variation independent of measured patient and hospital characteristics, suggesting the need for further work to evaluate the causes of variation at the hospital level and potential consequences of variation across hospitals.

Mortality rate estimation and standardization for public reporting: Medicare’s Hospital Compare.
The authors calibrated Bayesian recommendation systems by checking, out of sample, whether predictions aggregate to give correct general advice derived from another sample. Their process leads to substantial revisions in the Hospital Compare model for acute myocardial infarction mortality. They found that indirect standardization, as currently used by Hospital Compare, fails to adequately control for differences in patient risk factors and systematically underestimates mortality rates at the low volume hospitals. They proposed direct standardization instead.

Spending on care after surgery driven by choice of care settings instead of intensity of services.
The rising popularity of episode-based payment models for surgery underscores the need to better understand the drivers of variability in spending on postacute care. Examining postacute care spending for fee-for-service Medicare beneficiaries the researchers found that it varied widely between hospitals in the lowest versus highest spending quintiles but the variation diminished considerably after adjustment for postacute care setting (home health care, outpatient rehabilitation, skilled nursing facility, or inpatient rehabilitation facility).
