Official title

Title: Effectiveness of Empiric Antiviral Treatment for Hospitalized Community Acquired Pneumonia During the Influenza Season (U18)

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Current guidelines recommend early initiation of empiric antibiotic therapy to cover typical and atypical bacteria that may cause community-acquired pneumonia (CAP). Influenza antiviral therapy in patients with suspected or confirmed influenza. However, many clinicians do not suspect influenza among patients with CAP or other acute lower respiratory tract illness (LRTI) and often do not test for influenza. Additionally, results from currently available diagnostic tests for influenza may be delayed and several tests have low sensitivity and will give false negative results. Thus, anti-influenza treatment for patients with hospitalized influenza CAP and LRTI is frequently initiated late if at all. There is an association between delayed time to administration of empiric antibiotic therapy with increased clinical failure and mortality. As a result, empiric antibiotic therapy for patients with suspect CAP is begun within 4 - 6 hours of hospitalization. This has recently been demonstrated for delayed antiviral treatment as well. We hypothesize that, as happens with early empiric antibiotics for bacterial CAP, a standardized approach of adding early empiric anti-influenza therapy during the influenza season to hospitalized patients with suspect CAP and LRTI will improve clinical outcomes of patients with influenza associated CAP and LRTI. To test our hypothesis we plan a prospective, randomized, multicenter clinical trial of hospitalized patients with acute LRTI, including suspect CAP, during . If early anti-influenza medications were not included on the patients admission orders, patients will be randomized to standard care, including empiric antibacterial therapy as recommended by ATS/IDSA guidelines plus standard influenza diagnostics and treatment (Standard of care) versus early initiation of empiric antiinfluenza therapy plus standard care, e.g. empiric antibacterial (oseltamivir group). The primary study outcome will be development of clinical failure and selected clinical outcomes during the 30 days after enrollment. Other clinical outcomes that will be compared between study groups include time to clinical stability, duration of hospitalization, development of cardiovascular events, re-hospitalization, short-term mortality (30 days), and long-term mortality (1 year). The secondary study outcome will be the cost-effectiveness of the intervention.
