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.

Inpatient financial burden of atopic dermatitis in the United States.
Little is known about the inpatient burden of atopic dermatitis (AD). The researchers sought to determine some risk factors and financial-burden of hospitalizations for AD in the US. They found that the high prevalence of hospitalization resulted in total inpatient costs of $8,288,083 per-year for adults and $3,333,868 per-year for children. In conclusion, there is a substantial inpatient financial-burden of AD in the US.

Identifying specific combinations of multimorbidity that contribute to health care resource utilization: an analytic approach.
The objective was to identify specific combinations of chronic conditions, functional limitations, and geriatric syndromes associated with direct medical costs and inpatient utilization. The multimorbid population is heterogeneous and there is considerable variation in how specific combinations of morbidity influence resource use. Functional limitations were more important than many chronic diseases in explaining resource use.

Cost of hospital admissions in Medicare patients with atrial fibrillation taking warfarin, dabigatran, or rivaroxaban.
The purpose of this study was to examine the impact of anticoagulant choice on inpatient costs in patients with nonvalvular atrial fibrillation (AF). Analysis used 3-way propensity matching to create groups from AF patients taking dabigatran, rivaroxaban, or warfarin, and were plausible candidates for all 3 anticoagulants. Predicted values from two models were multiplied together to estimate expected costs per patient-year. The study concludes from its data that patients with newly diagnosed AF taking 150 mg dabigatran or 20 mg rivaroxaban experience lower annual inpatient costs than patients taking warfarin, due to fewer hospital admissions for stroke, non-gastrointestinal-related hemorrhages, and heart failure events.

Cost of shingles: population based burden of disease analysis of herpes zoster and postherpetic neuralgia.
In order to determine the healthcare system burden of herpes zoster (HZ) using direct medical costs, researchers analyzed administrative healthcare data collected from 1997 to 2014. They found a large increase in incidence of HZ, with rising per episode medical and prescription costs but this was offset by dramatic drops in hospitalization rates, the net effect of which has been to hold the total costs relatively constant.

The hidden societal cost of antibiotic resistance per antibiotic prescribed in the United States: an exploratory analysis.
This study estimated the hidden societal cost of antibiotic resistance per antibiotic prescribed in the United States. It concluded that each ambulatory antibiotic prescription is associated with a hidden societal cost of antibiotic resistance (SCAR) that substantially increases the cost of an antibiotic prescription in the United States. This finding raises concerns regarding the magnitude of misalignment between individual and societal antibiotic costs.

Out-of-pocket spending for hospitalizations among nonelderly adults.
The researchers evaluated out-of-pocket spending associated with hospitalizations in order to assess how this spending varied over time and by patient characteristics, region, and type of insurance. They found that from 2009 to 2013, total cost sharing per inpatient hospitalization increased by 37 percent, from $738 in 2009 to $1013 in 2013 after adjusting for inflation and case-mix differences.

Costs of care for hospitalization for pemphigus in the United States.
The purpose of this study was to determine the incidence of and risk factors for hospitalization with pemphigus and cost of care. It concluded that there is a significant inpatient burden for pemphigus in the United States. Moreover, there appear to be racial/ethnic and health care disparities with respect to pemphigus, such that poor, nonwhite, and/or uninsured or underinsured patients have higher odds of hospitalization.

Hospital use by persons with HIV in the 21st century: a 5-state study.
The purpose of this study was to determine whether reductions in hospital utilization observed immediately after the availability of highly active antiretroviral therapy (between 1995 and 2000) have persisted into the 21st century. It found that the total number of hospitalizations by persons with HIV in the 5 study states fell by one third between 2000 and 2013 even though the number of persons living with HIV increased by >50%.

The effects of multiple chronic conditions on hospitalization costs and utilization for ambulatory care sensitive conditions in the United States: a nationally representative cross-sectional study.
A purpose of this study was to evaluate how multiple chronic conditions relate to inpatient hospitalization costs. It found that compared with costs for patients with 0 or 1 chronic condition, hospitalization costs per stay for overall ambulatory care sensitive conditions were 19 percent higher for those with 2 or 3 , 32 percent higher for those with 4 or 5, and 31 percent higher for those with 6+ conditions.

Association of postdischarge spending and performance on new episode-based spending measure.
The Centers for Medicare and Medicaid Services recently added the Medicare Spending per Beneficiary (MSPB) metric to its Hospital Value-Based Purchasing (HVBP) program. The researchers evaluated whether hospital performance was driven by spending before, during, or after hospitalization. They found that compared with low-cost hospitals, high-cost hospitals had significantly higher preadmission and index admission spending, but the largest differences were in postdischarge spending.

Pediatric inpatient hospital resource use for congenital heart defects.
The authors sought to estimate healthcare costs for infants, children, and adolescents with congenital heart defects (CHDs). Using the 2009 Healthcare Cost and Utilization Project Kids' Inpatient Database (KID), they found that hospitalizations for children with CHDs have disproportionately high hospital costs compared with other pediatric hospitalizations, and the 17% of hospitalizations with critical CHD diagnoses accounted for 27% of CHD hospital costs.

Trends in complicated newborn hospital stays & costs, 2002-2009: implications for the future.
The researchers used HCUP data to examine trends from 2002 through 2009 in complicated newborn hospital stays, and to explore the relationship between expected sources of payment and reasons for hospitalizations. They concluded that state Medicaid programs are paying for an increasing proportion of births and costly complicated births, and they suggested that policies to prevent common birth complications have the potential to reduce costs for public programs and improve birth outcomes.

Medicaid admissions and readmissions: understanding the prevalence, payment, and most common diagnoses.
The authors characterized acute care hospital admissions and thirty-day readmissions in the Medicaid population through a retrospective analysis in nineteen states. They found that Medicaid readmissions were both prevalent and costly, and that they represented 12.5 percent of Medicaid payments for all hospitalizations, with the most prevalent diagnostic categories being mental and behavioral disorders and diagnoses related to pregnancy, childbirth, and their complications.
