Study to Determine Quicker Methods of Diagnosing Pneumonia Caused by a Breathing Machine in Critically Ill Patients

December 22, 2019 updated by: Ivor Douglas, Denver Health and Hospital Authority

Rapid Bacterial Identification and Antibiotic Resistance Testing in Critically Ill Adults at Risk for Ventilator Acquired Pneumonia (VAP).

Critically ill patients on a breathing machine are at risk of developing a type of pneumonia called Ventilator Acquired Pneumonia (VAP). The purpose of this study is to determine if regular lung rinses sent for microbiological testing can reduce the time to diagnose VAP. The study also plans to test the accuracy and speed of a new technology, using multiplexed automated digital microscopy, to identify the germs causing the VAP.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Ventilator-associated pneumonia (VAP) is a common, life-threatening hospital-acquired infectious complication of prolonged mechanical ventilation (MV). Despite aggressive efforts to prevent VAP, rates remain high because clinical diagnosis is imprecise and microbiological diagnosis is frequently delayed. Diagnosis of VAP depends on clinical signs as well as microbiologic evidence from Bronchioalveolar Lavage (BAL) cultures. Ordinarily, these cultures are only ordered after the patient presents with clinical signs and symptoms of VAP, which can significantly delay diagnosis and effective therapy. This research proposes to implement additional surveillance BAL cultures in order to reduce the time to diagnosis of VAP in mechanically ventilated critically ill adults. To further reduce the time to diagnosis of VAP, this research aims to test part of the BAL cultures using a novel flowcell/surface-capture device that allows direct from specimen visualization of bacteria using multiplexed automated digital microscopy (BACcel™) for rapid bacterial identification and antibiotic resistance testing. Additionally, molecular assays of the BAL sample will characterize lower respiratory tract antimicrobial peptide host-innate immune molecule and local anti-oxidant defenses in mechanically ventilated adults at risk for VAP.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
