Predictors of mortality for preterm infants with intraventricular hemorrhage: a population-based study.
This study examined the risk factors for mortality in preterm infants with intraventricular hemorrhage (IVH). An overall inpatient mortality occurred in 10% of the cohort of 7437 preterm infants born between 2005 and 2014. Mortality risk was independently associated with a variety of factors including male sex, Asian race, lower gestational age, higher IVH grade, gastrotomy, tracheostomy, and shunt infection.

Association of obesity with severity of heart failure exacerbation: a population-based study.
Researchers investigate the associations of obesity with severity of heart failure exacerbation and in-hospital mortality using population-based data from the State Inpatient Databases. Subjects were adults hospitalized for heart failure exacerbation in seven States from 2012 to 2013. The researchers found that, based on large population-based data sets of patients with heart failure exacerbation, obesity was associated with higher acute severity measures but lower in-hospital mortality.

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 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.
