Respiratory viral testing and antibacterial treatment in patients hospitalized with community-acquired pneumonia.
Researchers studied the frequency of respiratory viral testing and its associations with antimicrobial utilization in adult patients hospitalized with community-acquired pneumonia. They found that, of patients with pneumonia on admission, 24.5% were tested for respiratory viruses, 94.8% were tested for influenza, and 20.7% were tested for other viruses. They concluded that a minority of patients hospitalized with pneumonia were tested for respiratory viruses; only a fraction of potential viral pathogens were assayed; and patients with positive viral tests often received long antibacterial courses.

De-escalation of empiric antibiotics following negative cultures in hospitalized patients with pneumonia: rates and outcomes.
This study assessed antibiotic de-escalation practices across hospitals and their associations with outcomes in hospitalized patients diagnosed with pneumonia with negative cultures. The authors included 14,170 adults admitted with pneumonia in 2010-2015 to 164 US hospitals if they had negative blood and/or respiratory cultures and received both anti-MRSA and antipseudomonal agents other than quinolones. If empiric drugs were stopped on day 4 while continuing another antibiotic it was defined at de-escalation. Patients were propensity adjusted for de-escalation and compared on in-hospital 14-day mortality, late deterioration with ICU transfer, length-of-stay (LOS) and costs. Thirteen percent (1924 patients) had both initial empiric drugs stopped by hospital day 4. De-escalation rates at hospitals ranged from 2-35% and the established rate quartiles were not significantly associated with outcomes. Even at hospitals in the top quartile of de-escalation, the de-escalation rates were lower than 50%.

Antibiotics for aspiration pneumonia in neurologically impaired children.
The objective of the study was to compare hospital outcomes associated with commonly used antibiotic therapies for aspiration pneumonia in children with neurologic impairment (NI). The investigators concluded that anaerobic therapy appeared to be important in the treatment of aspiration pneumonia in children with NI. They suggested that while Gram-negative coverage alone was associated with worse outcomes, its addition to anaerobic therapy may not yield improved outcomes.

Infant respiratory syncytial virus bronchiolitis and subsequent risk of pneumonia, otitis media, and antibiotic utilization.
This study looked at infant respiratory syncytial virus (RSV) bronchiolitis and its association with increased odds of pneumonia, otitis media, and antibiotic utilization in infants 7-12 months. The data suggested the potential value of future RSV vaccination programs on subsequent respiratory health.
