Randomized Controlled Trial
Digitoxin for Airway Inflammation in Cystic Fibrosis: Preliminary Assessment of Safety, Pharmacokinetics, and Dose Finding.
Cystic fibrosis (CF) lung disease progresses by a combination of airway inflammation, bacterial colonization, and infection. Airway inflammation is predominantly neutrophilic and complicates airway clearance therapies through cellular debris; excessive DNA; excessive and viscous mucus; and high concentrations of neutrophils, IL-8, and related cytokines liberated along the nuclear factor-κB signaling pathway. ⋯ At a dose of 0.1 mg daily for 28 days, digitoxin was safe for adults with CF lung disease, but it did not achieve a significant decrease in sputum inflammatory markers. Clinical trial registered with www.clinicaltrials.gov (NCT00782288).

There are limited data on physiotherapy during extracorporeal membrane oxygenation (ECMO) for acute respiratory distress syndrome (ARDS). ⋯ Physiotherapy during ECMO is feasible and safe when performed by an experienced team and executed in stages. Although our study suggests an association with improved ICU mortality, future research is needed to identify potential barriers, optimal timing, dosage, and safety profile.

Several intensive care unit (ICU) organizational practices have been associated with improved patient outcomes. However, the uptake of these evidence-based practices is unknown. ⋯ The diffusion of evidence-based ICU organizational practices has been variable across the state of Pennsylvania. Only half of Pennsylvania ICUs have intensivists dedicated to the ICU. Variable numbers use clinical protocols for life-saving therapies, and few use structured family engagement strategies. In contrast, the diffusion of non-evidence-based practices, including overnight ICU attending physician staffing, is increasing. Future research should focus on promoting implementation of organizational evidence to promote high-quality ICU care.

Observational Study
Variation in Postsepsis Readmission Patterns: A Cohort Study of Veterans Affairs Beneficiaries.
Rehospitalization is common after sepsis, but little is known about the variation in readmission patterns across patient groups and care locations. ⋯ Hospital readmission rates after sepsis were similar by site and admission year. Heart failure, pneumonia, sepsis, and urinary tract infection were common readmission diagnoses across all patient groups. Readmission for infection and potentially preventable diagnoses were more common in older patients and patients discharged to nursing facilities.

In the United States, approximately 20% of patients hospitalized with pneumonia are readmitted to a hospital within 30 days. Given the significant costs and healthcare system use resulting from unplanned readmissions, pneumonia readmission rates are a target of national quality measures. Patient do-not-resuscitate (DNR) status strongly influences hospital pneumonia mortality measures; however, associations between DNR status and 30-day readmissions after pneumonia are unclear. ⋯ Patients with an early DNR order have a lower risk for readmission after a pneumonia hospitalization. Unmeasured DNR status weakly confounds hospital readmission measures; accounting for patient DNR status would alter readmission ratings for a small number of hospitals.
