Scientific titleClinical value of LightCycler® SeptiFast Test compared to conventional blood cultures for antimicrobial detection in post-operative septic patients: a prospective, randomised single-centre trial
Study acronymSeptiFast
Study objectivesAntimicrobial detection in septic patients with the LightCycler® SeptiFast Test leads to accelerated administration of appropriate antibiotic therapy.
Ethics approval(s)Ethics Committee of Charité - University Medicine Berlin, 12/03/2009, ref: EA1/043/09
Health condition(s) or problem(s) studiedSepsis due to abdominal infection or hospital acquired pneumonia
InterventionPatients will be randomised in two groups. Samples for the LightCycler® SeptiFast Test will be taken in both groups parallel to conventional blood cultures. In group 1, the results of the LightCycler® SeptiFast Test will be made available for the treating physician, in group 2, results of the LightCycler® SeptiFast Test will be analysed retrospectively. Both groups will be assessed for changes in the initial empirical therapy (end of intervention), both groups will be followed up until resolution of all clinical signs of sepsis or discharge from the Intensive Care Unit (ICU) or for a maximum period of 30 days.
Intervention typeOther
Primary outcome measure(s)

Frequency of changes of the initial antibiotic treatment related to diagnostic procedures and time until appropriate antibiotic treatment, assessed at the end of data collection.

Key secondary outcome measure(s)

1. Rate of patients with organisms detected by the LightCycler® SeptiFast Test compared to all patients with clinically confirmed sepsis
2. Rate of empirical treatment that was retrospectively confirmed to be appropriate
3. Number of days with antibiotic treatment
4. Decreasing severity of illness (Simplified Acute Physiology Score [SAPS], Sequential Organ Failure Assessment [SOFA], 28-item Therapeutic Intervention Score [TISS-28]) during treatment
5. Length of mechanical ventilation
6. Length of intensive care unit (ICU) stay
7. Length of hospital stay
8. Therapy costs

All assessed at the end of data collection.

Completion date30/04/2012
