Impact of Using Mini-Bronchoalveolar Lavage as a Diagnostic Test for Ventilator-Associated Pneumonia

Not Applicable

Completed

• Conditions: Ventilator-Associated Pneumonia
• Interventions: Device: Bronchoalveolar lavage

• Registration Number: NCT00319644
• Lead Sponsor: University of California, San Francisco

Brief Summary

The proposed study will evaluate adult patients admitted to the medical or surgical intensive care units (ICUs) at San Francisco General Hospital (SFGH). On admission, patients will be randomized in a 1:1 manner to the mini-bronchoalveolar lavage (BAL) quantitative culture arm in the setting of suspected ventilator-associated pneumonia (VAP) versus the tracheal aspirate culture arm, which is the current test available at SFGH.

Detailed Description

Patients will be randomized to either Mini-Bal or tracheal aspirate then samples will be taken to the lab for culture. Comparative analysis will then be performed based upon lab results.

Primary Outcome Measures

Name	Time	Method
Change in Antibiotic Usage or Exposure	It is theorized that patients randomized to the tracheal aspirate will receive an average of 15 days of antibiotics while patients randomized under the minibal arm will receive an average of 10 days of antibiotics	We expect that 100-110 adult patients will have clinically suspected VAP over a 2-year period. We assume that 50 patients with suspected VAP will be randomized to mini-BAl, and 50 patients will be randomized to tracheal aspirate. We expect that patients randomized to tracheal aspirate group will receive an average of approximately 14 total days of antibiotics over their ICU stay. This study will have \>80% power to detect a difference of 4 days of antibiotics (i.e. average of 10 days in mini-BAL group) with a 7-day standard deviation in both groups (alpha error level 5%).
Antibiotics Exposure Days	15 days	We hypothesize that Mini-BAL quantitative culture in place of tracheal aspirate culture will reduce the total days of antibiotics exposure
