Acute exacerbation of chronic obstructive pulmonary disease and subsequent risk of emergency department visits and hospitalizations for atrial fibrillation.
Although emerging evidence has suggested the relationship of chronic obstructive pulmonary disease with atrial fibrillation (AF), little is known about whether acute exacerbation of chronic obstructive pulmonary disease (AECOPD) increases the risk of repeated AF-related healthcare utilization. The investigators found that among patients with existing AF, AECOPD was associated with a higher risk of AF-related ED visit or hospitalization in the first 90-day post-AECOPD period.

National landscape of unplanned 30-day readmissions in patients with left ventricular assist device implantation.
This study tracked unplanned 30-day readmissions in patients who had undergone left ventricular assist device (LVAD) implantation during 2013. Data from the Healthcare Cost and Utilization Project (HCUP) National Readmission Database was used. Out of 2,235 patients who had an LVAD implantation, 29.7% had at least 1 unplanned readmission within 30 days. The top reasons for readmission were implant complications (14.9%), congestive heart failure (11.7%), and gastrointestinal bleeding (8.4%). Predictors of readmission included a prolonged length stay during the primary admission, Medicare insurance, and discharge to a short-term facility.

Association of inferior vena cava filter placement for venous thromboembolic disease and a contraindication to anticoagulation with 30-day mortality.
Despite the absence of data from randomized clinical trials, professional societies recommend inferior vena cava (IVC) filters for patients with venous thromboembolic disease (VTE) and a contraindication to anticoagulation therapy. Prior observational studies of IVC filters have suggested a mortality benefit associated with IVC filter insertion but have often failed to adjust for immortal time bias. The purpose of this study was to determine the association of IVC filter placement with 30-day mortality after adjustment for immortal time bias.

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.
