Antibiotics Continuous Infusion at Home

STATISTICAL ANALYSIS: This is an interventional monocentric study. The primary endpoint of the study is a reduction in hospitalization days. The study population is divided into 4 treatment arms: assuming that the average length of hospitalization for the standard treatment of a severe infection, for each of the types of antibiotic studied, is 14 days, with the treatment envisaged by the study it is assumed to reduce this duration,for all 4 treatment arms, to a number equal to or less than 12 days. With these premises, applying the One sample t-test design method, assuming α = 0.05 and β = 0.1, the number of patients expected is 9 for each treatment arm. Considering a 30% dropout, the total population to be enrolled for each type of antibiotic is 12 patients. In total, the study will enroll 48 patients. The study provides for an observation period of 30 days from enrollment. During this period, efficacy, safety and pharmacokinetic data will be collected for each treatment arm.
