Information provided by (Responsible Party):
University of Missouri-Columbia
The purpose of this study is to test a new method for diagnosing and monitoring Ventilator-Associated Pneumonia, which is a major killer among ICU patients. The method requires analysis of a small amount of the patient's blood for concentration of a hormone called Procalcitonin.

Condition Intervention
Ventilator Associated Pneumonia Device: Procalcitonin Level

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Prospective
Official Title: Clinical Utility of Serum Procalcitonin in the Management of Ventilator-Associated Pneumonia

Further study details as provided by University of Missouri-Columbia:

Primary Outcome Measures:
  • Correlation of Procalcitonin concentration with the LungGuardian-derived Pneumonia Score in mechanically ventilated surgical intensive care unit patients. Using the data collected a positive and negative predictive value will be calculated. [ Time Frame: Once daily ]

Secondary Outcome Measures:
  • antibiotic status (appropriateness, effectiveness, discontinuation criteria) [ Time Frame: Once daily ]
  • intubation date [ Time Frame: Once daily ]
  • microbiology data [ Time Frame: Once daily ]
  • PCT levels [ Time Frame: Once daily ]
  • pneumonia-related symptoms (including tracheal secretion character, body temperature, oxygenation, and WBC counts) [ Time Frame: Once daily ]

Enrollment: 29
Study Start Date: September 2008
Study Completion Date: August 2014
Primary Completion Date: August 2014 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Procalcitonin Level
    Procalcitonin concentrations will be determined every day and will be compared with the clinical diagnosis based upon standard clinical practice. All subjects enrolled will be followed until the patient is either extubated or discharged from the SICU.
    Other Name: PCT
Detailed Description:
Ventilator-associated pneumonia is a leading cause of mortality in critically ill patients. The purpose of this study is to evaluate the relationship between the onset/progress/resolution of pneumonia and the levels of Procalcitonin, a prohormone whose concentrations fluctuate in response to bacterial infection.
