Conditions

Brief Summary

Phase IV, open-labeled, randomized and multicenter clinical trial to demonstrate the superiority of antibiotics with authorized indication for 7 days versus 14 days in the treatment of bloodstream infections produced by P. aeruginosa (BSI-PA).

Detailed Description

The project is designed to determine the optimal duration of antibiotic treatment for Pseudomonas aeruginosa bacteremia, by comparing an adequate antibiotic treatment regimen of 7 days (experimental arm) with another of 14 days (control arm). The evaluation of infection recurrences, mortality, number of free days of antibiotic treatment, adverse events and superinfections are included as secondary objectives.

Active antibiotic treatment will be considered any treatment with proven in vitro activity against the strain responsible for the patient's bacteremia, regardless of the administered dose.

Clinical rules are included in order to stop antibiotic treatment or continuation and re-evaluation in each arm of treatment.

This is a pragmatic study as the number or visits performed for the study are similar to the normal clinical follow-up for this patients. Final contact and final visit for the study will be performed at 90 days after the first positive blood culture.

Primary Outcome Measures
NameTimeMethod
Probability of achieving better DOOR/RADAR score for patients in the experimental group than in the control group30 days after treatment withdrawal

Probability of any given patient in the experimental arm to achieve better results than a patient in the control group assessed through their score in the DOOR/RADAR ( Desirability of Outcome Ranking/Response Adjusted for Duration of Antibiotic Risk) analysis.

This analysis categorizes patients in two steps:

1. A first ordinal clinical outcome ranking (DOOR), defined by the following mutually excluding categories:

1. Healing without incidences.

2. Healing with a proven or probable recurrence.

3. Healing with a serious adverse event.

4. No clinical cure.

5. Death.

2. A second classification in which patients from the same clinical outcome category are ranked according to the number of days of antibiotic treatment (RADAR).

Patients with a lower DOOR/RADAR score will be those with best outcomes in terms of clinical effectiveness as well as reduced exposure to antibiotic treatment.
