Stopping antibiotics early in older adults hospitalized with a viral lung infection

Early Discontinuation of Antibiotic Therapy in Elderly Patients Hospitalized for a Viral Infection

Not applicable Interventional Centre Hospitalier Universitaire, Amiens · NCT07030673

What this trial studies

Older adults hospitalized with signs of lower respiratory infection will have microbiological sampling within 48 hours and multiplex PCR testing to identify viral pathogens. When a viral infection is identified and there is no evidence of bacterial co-infection, the protocol calls for early discontinuation of antibiotics; patients will then be followed for clinical outcomes, complications, and need to restart antibiotics. The intervention is being implemented at university hospitals in France and compared with usual antibiotic management pathways. The goal is to measure safety, clinical recovery, and antibiotic exposure in this higher-risk, comorbid population.

Who should consider this trial

Good fit: Ideal candidates are people aged 65 or older who are hospitalized for a lower respiratory infection, have a microbiological diagnostic sample taken within 48 hours, and can provide informed consent (or have a representative who can).

Not a fit: Patients with septic shock, febrile aplasia, proven inhalation, purulent pleurisy or lung abscess, other bacterial infections requiring antibiotics, moribund patients, or those without timely microbiological sampling are unlikely to benefit from early antibiotic discontinuation.

Why it matters

Potential benefit: If successful, the approach could safely reduce unnecessary antibiotic exposure, antibiotic-related side effects, and contribution to antimicrobial resistance in elderly inpatients.

How similar studies have performed: Previous antibiotic stewardship efforts using rapid viral testing have reduced antibiotic use in some adult populations, but robust evidence specifically in frail elderly inpatients is limited.
