The aim of this study is to test if procalcitonin (PCT) guided antibiotic stewardship in patients with lower respiratory tract infection (LRTI) will be non-inferior, with at worst a 7.5% higher combined failure rate, as compared to standard care practice (current guidelines for LRTI) with reduced total antibiotic (AB) use and hospitalization rate and duration, respectively.

  Show Detailed Description


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Patients 18 years of age or older, admitted from the community or a nursing home with acute (i.e., at least 1 day but less than 28 days) LRTI as the main diagnosis consisting of having at least two of the following:

    • new or increased respiratory signs or symptoms (i.e., cough, sputum production, dyspnea, auscultatory findings of abnormal breath sounds and rales, pleuritic chest pain) with or without inflammatory signs (core body temperature > 38.0° C, leukocyte count > 10 or < 4 x 10^9 cells L-1).
    • CAP is defined by the presence of LRTI along with a new or increased infiltrate on chest radiograph. Severity scores of CAP (pneumonia severity index [PSI] and CURB-65) will be calculated.
    • COPD is defined by post-bronchodilator spirometric criteria according to the GOLD-guidelines as a FEV1/FVC ratio below 70% and the severity categorized into mild (FEV1 <= 80% of predicted), moderate (50% >= FEV1 < 80%), severe (30% >= FEV1 < 50%) and very severe (FEV1 < 30%), respectively. Severity of acute exacerbations of COPD will be graded as proposed. Acute bronchitis is defined as LRTI in the absence of an underlying lung disease or focal chest signs and infiltrates on chest X-ray, respectively. Patients who are on admission judged as having an LRTI but have another final diagnosis, will be classified as "others".
  2. Ability to understand verbal and written instructions and informed consent.

Exclusion Criteria:

  1. Patients unable to give written informed consent, e.g. with severe dementia or patients not understanding German (or other local language) and no translation (e.g. family members) available.
  2. Patients with active intravenous drug use.
  3. Severe immunosuppression (e.g. patients infected with human immunodeficiency virus infection and a CD4 count below 350 x 10^9/L, patients on immunosuppressive therapy after solid organ transplantation and neutropenic patients with present neutrophil count < 500 x 10^9/L and patients under chemotherapy with neutrophils 500-1000 x 10^9/L with an expected decrease to values < 500 x 10^9/L); patients with cystic fibrosis, infection with M. tuberculosis, L. pneumophila, Listeria spp. hospital stay within 14 days of inclusion.
  4. Accompanying chronic (e.g. osteomyelitis), abscess (e.g. brain, pleural empyema) infection or endocarditis.
  5. Terminal and very severe medical co-morbidity where death is imminent or has to be expected in the current hospitalization (e.g. due to malignancy, cardiac, renal or hepatic failure, comfort therapy).
