The association between major depressive disorder and outcomes in older veterans hospitalized with pneumonia.
The aim of this study was to examine the association between depression and outcomes, including mortality and intensive care unit admission, in veterans hospitalized with pneumonia. It found that patients with untreated depression had a significantly higher 30-day and 90-day mortality, as well as significantly higher intensive care unit admission rates, compared to patients with treated depression.

Treatment trends and outcomes in healthcare-associated pneumonia.
This retrospective cohort study assessed changes in hospital rates of concordant antibiotic use over time and their correlation with outcomes related to management of healthcare-associated pneumonia (HCAP). The study concluded that only 1 in 5 patients with risk factors for HCAP received treatment that was fully in accordance with guidelines, and many received community-acquired pneumonia (CAP) therapy instead.

Application of a risk score to identify older adults with community-onset pneumonia most likely to benefit from empiric pseudomonas therapy.
The researchers assessed the impact of empiric Pseudomonas pharmacotherapy on 30-day mortality in hospitalized patients with community-onset pneumonia stratified according to their risk (low, medium, or high) of drug-resistant pathogens. By using a risk score, they found that empiric Pseudomonas therapy was associated with lower 30-day mortality in the high-risk group but not the low- or medium-risk groups.

Association between initial route of fluoroquinolone administration and outcomes in patients hospitalized for community-acquired pneumonia.
The objective of this study was to compare outcomes of hospitalized patients with community-acquired pneumonia receiving intravenous vs oral respiratory fluoroquinolones. The authors concluded that there was no association between initial route of administration and outcomes.

Outcomes of patients with healthcare-associated pneumonia: worse disease or sicker patients?
The researchers sought to determine the contribution of healthcare-associated pneumonia (HCAP) criteria to case-fatality rate. They found that, after adjustment for differences in patient characteristics, HCAP was associated with greater case-fatality rate than community-acquired pneumonia, possibly due to HCAP organisms or to HCAP criteria themselves.
