Influenza testing and treatment among patients hospitalized with community-acquired pneumonia.
This study looked at testing rates for influenza in hospitalized patients admitted for community-acquired pneumonia (CAP) and whether it is associated with antiviral treatment and shorter antibiotic courses. The study included patients admitted in 179 US hospitals with pneumonia from 2010 to 2015. The authors assessed influenza testing and compared antimicrobial utilization and the outcomes of test-positive, test-negative, and untested patients. Among 166,268 patients with CAP, 23.3% were tested for influenza, of whom 11.5% tested positive. Testing increased from 15.4% to 35.5% from 2010 to 2015 and was more than triple the rate during flu season (October-May) vs June to September. Patients who tested positive for influenza received antiviral agents more often and antibiotics less often and for shorter courses than patients testing negative. Patients who received early antiviral treatment with oseltamivir experienced lower 14-day in-hospital mortality, lower costs, and shorter length of stay vs patients receiving oseltamivir later or not at all.

Temporal trends in antimicrobial prescribing during hospitalization for potential infection and sepsis.
This study examined whether the push to administer antimicrobials to prevent sepsis has increased antimicrobial use in general. This observational cohort study of hospitalized patients at 152 hospitals in 2 health care systems during 2013 to 2018 looked at almost 1.6 million patients (81% male), admitted via the emergency department with 2 or more systemic inflammatory response syndrome (SIRS) criteria. From 2013 to 2018 first antimicrobial administration to patients with sepsis decreased by 37 minutes. At the same time, antimicrobial use within 48 hours, days of antimicrobial therapy, and receipt of broad-spectrum coverage decreased among the broader cohort of patients with systemic inflammatory response syndrome (SIRS). This may have caused a decrease in in-hospital mortality, 30-day mortality, length of hospitalization, new MDR culture positivity, and new MDR blood culture positivity over the study period among both patients with sepsis and those with SIRS. For the overall hospital population there was no evidence that increasing antimicrobial timing for sepsis was associated with increasing antimicrobial use or impaired antimicrobial stewardship.
