Hospital variation in renal replacement therapy for sepsis in the United States.
This retrospective cohort study estimated the risk- and reliability-adjusted rate of acute renal replacement therapy use for patients with sepsis and acute kidney injury at each hospital sampled by the Nationwide Inpatient Sample in 2011. The investigators examined the association between hospital-specific renal replacement therapy rate and in-hospital mortality and hospital costs after adjusting for patient and hospital characteristics.

Cardiac arrest survival in pediatric and general emergency departments.
Understanding whether pediatric emergency departments (EDs) have higher survival than general EDs may help identify ways to improve care for all patients with out-of-hospital cardiac arrest (OHCA). Researchers sought to determine if OHCA survival differs between pediatric and general EDs. In their nationally representative sample, survival from nontraumatic OHCA was higher in pediatric EDs than general EDs. Survival did not differ in traumatic OHCA.

Epidemiology of eczema herpeticum in hospitalized U.S. children: analysis of a nationwide cohort.
This study used data from the Nationwide Inpatient Sample 2002-2012 to determine incidence, risk factors, comorbidities, costs, length of stay, and mortality in hospitalized children with Eczema herpeticum (EH). A higher risk was associated with younger age and non-white ethnicity (Asian in particular). However there was less frequency of hospitalization associated with lower income quartiles. The mortality incidence was 0.1%.

Impact of health system affiliation on hospital resource use intensity and quality of care.
This study assessed the impact of hospital affiliation, centralization, and managed care plan ownership on inpatient cost and quality. It found that hospitals affiliated with health systems had a higher cost per discharge and better quality of care compared with independent hospitals. Centralized systems in particular had the highest cost per discharge and longest stays. Independent hospitals with managed care plans had a higher cost per discharge.

Obesity and severity of acute exacerbation of chronic obstructive pulmonary disease.
A study was done to determine if there was an increase in severity and mortality with chronic obstructive pulmonary disease (COPD) patients who were also obese. Researchers used data from 2012-2013 State Inpatient Databases data of seven U.S. states. 17% of COPD patients in the database were defined as obese. Obesity was shown to increase use of ventilation, increased hospital stays but not in-hospital mortality.

The impact of hospital volume on racial differences in complications, readmissions, and emergency department visits following total joint arthroplasty.
This study evaluates the impact of hospital volume on racial differences in outcomes following joint replacement. The study authors concluded that adjusting for hospital volume does not alter the risk of readmissions and ED use associated with minority race/ethnicity, suggesting that hospital volume alone may be insufficient to explain racial differences in outcome.

Trends in rate of seizure-associated hospitalizations among children <5 years old before and after rotavirus vaccine introduction in the United Sates, 2000-2013.
Since rotavirus vaccine introduction, hospitalizations for treatment of acute gastroenteritis have decreased. Researchers assessed whether there has been an associated decrease in seizure-associated hospitalizations. Their analysis provides evidence for a decrease in seizure hospitalizations following rotavirus vaccine introduction in the United States, with the greatest impact in age groups with a high rotavirus-associated disease burden and during rotavirus infection season.

On the relative role of different age groups during epidemics associated with respiratory syncytial virus.
This study evaluated the roles played by individuals in different age groups during respiratory syncytial virus (RSV) epidemics in the United States between 2001 and 2012, using the previously defined relative risk (RR) statistic estimated from the hospitalization data from the Healthcare Cost and Utilization Project. Its estimates suggest the prominent relative roles of children aged </=10 years (particularly among those aged 3-6 years) in propagating RSV epidemics.

A quantitative observational study of physician influence on hospital costs.
Physicians serve as the nexus of treatment decision-making in hospitalized patients; however, little empirical evidence describes the influence of individual physicians on hospital costs. In this study, the extent to which hospital costs vary across physicians and physician characteristics is examined. Among other findings, the investigators observed sizable variation in average costs of hospital inpatient stays across medical specialties.

Association between atopic dermatitis and serious cutaneous, multiorgan and systemic infections in US adults.
This study sought to determine whether adults with atopic dermatitis (AD) have an unusually large number of serious infections and related outcomes. Using data from the 2002 to 2012 National Inpatient Sample Adults, it found that adults with AD had increased cutaneous, respiratory, multiorgan, and systemic infections, which were associated with a considerable cost burden.

Racial/ethnic disparities in readmissions in US hospitals: the role of insurance coverage.
This study examined differences in rates of 30-day readmissions across patients by race/ethnicity and the extent to which these differences were moderated by insurance coverage. It found higher readmission risk for non-Hispanic blacks, compared with non-Hispanic whites, among those covered by Medicare and private insurance, but lower risk among uninsured and similar risk among Medicaid.

The effects of Medicare accountable organizations on inpatient mortality rates.
This study examined whether Medicare Accountable Care Organizations (ACOs) have improved hospital quality of care, specifically focusing on preventable inpatient mortality. The investigators concluded that, on average, Medicare ACO hospitals are not associated with improved mortality rates for the studied inpatient quality indicator conditions. They suggest that stakeholders may potentially consider providing ACOs with incentives or designing new programs for ACOs to target inpatient mortality reductions.

U.S. pediatric burn patient 30-day readmissions.
The objectives of the study were to determine unscheduled 30-day readmission rates for pediatric burn patients and to identify readmission reasons. The investigators used the 2013-2014 National Readmission Database to produce 30-day all-cause unscheduled readmission rates by patient and hospital characteristics.
