Antibiotic Use in French Nursing Home

CONTEXT: France is still one of the biggest consumers of antibiotics in Europe. An explanation for this increase in consumption would be aging. Thus, part of this aging population lives in nursing home, where the urinary tract infection is the second most suspected pathology. However, it can most often be bacteriuria requiring no antibiotic therapy. In nursing home, nurses alert prescribers when an infection is suspected by describing clinical signs. However, their propensity to perform too rapidly and systematically an examination with dipsticks leads physicians to prescribe antibiotic. This is how a program called ATOUM is set up to reduce the prescription of antibiotics in nursing home. The present ATOUM 4 study builds on this program. OBJECTIVE: To measure the effect of a nurse-centered multimodal intervention involving training and sensitization on urinary tract infection, asymptomatic bacteriuria, antibiotic resistance and interprofessional communication on antibiotic therapy. METHODS: This will be a randomized double-arm interventional study in 40 nursing home. The intervention group of 20 nursing home will receive a blended-learning intervention.The primary outcome will be the percentage of reduction in antibiotic prescription at the end of the twelve months following the first visit to nursing home. This data, aggregated by nursing home, will be obtained from the structures concerned via their prescription registration system.
