Uno score per identificare il lattante febbrile di età ≤90 giorni con stick urinario anomalo a basso rischio di infezione batterica invasiva (IBI)

A score to identify the febrile infant aged ≤90 days with abnormal urine stick at low risk of invasive bacterial infection (IBI) Analyzing the data recorded in the emergency room (ER) of one 3° level of care Spanish center relating to 662 infants in good general condition, aged ≤90 days with fever without localization signs and altered urine stick, the authors calculated a score to identify the infants at low risk of invasive bacterial infections (IBI). Age (≤15 days of life), and blood values of procalcitonin (PCT ≥0.6 ng / mL) and C reactive protein (CRP ≥ 20 mg / L) were independent risk factors for invasive bacterial infection (RISeuP score). This score was then applied prospectively to 449 infants enrolled in 21 ERs and managed according to the individual centers’ protocols, for validation. The results were comparable, however, in the absence of data relating to the treatment received, the authors' conclusions regarding the possible home management of infants at low risk of IBI require careful verification.
