POCT PCT in Outpatient LRTI

Status Completed

Clinical Trial Summary

Lower respiratory tract infections (LRTI) in patients with chronic lung diseases are a common acute reason to consult respiratory practitioners and often lead to inadequate prescription of antibiotics. The primary objective of the investigators study was to determine the diagnostic accuracy of point-of-care testing (POCT) for procalcitonin (PCT) in identifying pneumonia as a bacterial infection in outpatients with LRTI.

Clinical Trial Description

Lower respiratory tract infections (LRTI) are a common acute reason to consult general practitioners or lung specialists and most patients receive an antibiotic prescription. Despite the vast majority of LRTI are caused by viruses, the lack of clinical, radiological, and laboratory tests to safely rule out bacterial involvement in LRTI still drives antibiotic treatment today Procalcitonin (PCT) has been shown to be a useful biomarker for differentiating between viral and bacterial infections in the emergency department and is now available as a point-of-care testing (POCT). The primary objective of the investigators study was to determine the diagnostic accuracy of POCT PCT in identifying bacterial infection in outpatients with LRTI. All patients aged 18 years or older with signs and symptoms of an LRTI as the leading diagnosis of the respiratory physicians are eligible. The medical assistant measure PCT from venous or capillary whole blood using the portable commercially available BRAHMS PCT direct point-of-care test (Thermo-Fischer Scientific). The stepwise procedure involve pipetting 20µl of the sample into the test disc before loading this onto the analyzer and pressing run. This immunoassay provides a quantitative result in 20 minutes. In suspicion of pneumonia (positive auscultation finding or clinical noticed symptoms compatible with pneumonia) a chest x-ray will be done. Members of the study team conduct standardised phone interviews of all participants on day 28. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
