Use Of Procalcitonin Level For Guidance of The Treatment of Suspected Community Acquired Pneumonia
An observational study of Pneumonia and Radiographic Lung Infiltrates, run by Winthrop University Hospital at 1 site in United States.
Trial summary
The purpose of the study is to learn if a blood test is helpful to the doctors in deciding whether you need antibiotic therapy for possible pneumonia. The blood test is called a Procalcitonin level and sometimes the test reflects infection with certain bacteria (germs). Read more about this study

About this study
The purpose of the study is to learn if a blood test is helpful to the doctors in deciding whether you need antibiotic therapy for possible pneumonia. The blood test is called a Procalcitonin level and sometimes the test reflects infection with certain bacteria (germs). When the doctors learn the results of these blood tests, they may be able to stop some of the antibiotic medications that they may have given to the patients. The study is designed, so that on a randomized basis (50/50 chance) the results from measuring Procalcitonin will be given to the patients' doctor. When the doctor receives these results, he/she may use this information, along with other information, to decide whether to continue antibiotic therapy.
Read the detailed description
To evaluate the usefulness of serum Procalcitonin level measured to guide the antibiotic treatment of patients with radiographic lung infiltrates.The subjects involved in the study will be divided in two arms ,study arm where the caregivers will know the result of Procalcitonin level and they can change /withheld the antibiotic for the subjects.In other arm only investigators will know the Procalcitonin level. We expect to enroll 100 patients.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.

The blood test is called a Procalcitonin level and sometimes the test reflects infection with certain bacteria (germs). When the doctors learn the results of these blood tests, they may be able to stop some of the antibiotic medications that they may have given to the patients.

Questions about this trial
What is this clinical trial studying?
An observational study of Pneumonia and Radiographic Lung Infiltrates, run by Winthrop University Hospital at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 15 Dec 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Differences in antibiotic discontinuation as an effect of the caregivers learning Procalcitonin levels for the therapy of new radiographic lung infiltrates (time frame: 1 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00914550, which also lists 8 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Dec 2014.
