Information provided by (Responsible Party):
Fraser Health
Patients in the ICU whose infection is resolving will be randomized to standard duration of antibiotics compared to duration determined by a combination of a procalcitonin value and a simple evaluation of clinical status.

Condition Intervention Phase
Infection Other: PCT and clinical algorithm for stopping abx Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Pilot Study to Evaluate a Procalcitonin-Based Algorithm for Duration of Antibiotic Therapy in Critically Ill Patients

Primary Outcome Measures:
  • Antibiotic- free days and alive at 14 days after ICU admission [ Time Frame: 14 days ]

Secondary Outcome Measures:
  • mortality at 28 days [ Time Frame: 28 days ]
  • mortality at 90 days [ Time Frame: 90 days ]
  • ventilator days at 28 days [ Time Frame: 28 days ]
  • ICU free days at 28 days [ Time Frame: 28 days ]
  • relapsed infection [ Time Frame: 30 days ]
  • rates of CDAD [ Time Frame: 30 days ]
  • colonization/infection with VRE/MRSA over next 30 days [ Time Frame: 30 days ]

Enrollment: 1

Study Completion Date: September 2013
Primary Completion Date: September 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: standard care
Abx will be determined by the managing physician
Experimental: experimental arm
Abx determined by normalization of PCT and basic clinical parameters
Other: PCT and clinical algorithm for stopping abx
In the experimental arm, antibiotics will be stopped based upon the PCT-guided algorithm. This PCT algorithm also incorporates clinical parameters to ensure utmost safety for the patients. These clinical parameters are; resolution of fever (temperature less than 38.3 and greater than 36.0), shock (on no vasopressors), and leukocytosis (<12,000 and >4,000).
