About this study
The main objective of this study is to investigate prevalence and risk factors for community-acquired pneumonia (CAP) and its interaction with comorbidities in an unselected group of adult patients receiving outpatient and inpatient care. In addition, information on HIV as a risk factor for CAP and on CAP in immunocompromised patients is collected.
Read the detailed description
The CAPNETZ study is a prospective, multicenter observational study investigating community-acquired pneumonia (CAP). Patients are recruited from outpatient and inpatient settings at hospitals and from primary care physicians (primarily specialists) and are followed for a period of six months. All CAP patients who meet the inclusion and exclusion criteria, consent to participate, and in whom the presence of a newly developed, community-acquired pneumonia can be verified are invited to participate. The baseline examination includes a detailed medical history, medication history, and a physical examination to record clinical and vital signs. In addition, the results of routine clinical imaging are documented, and biosamples (blood, urine, and respiratory specimens) are collected for clinical chemistry and microbiological analysis. Further in-person visits to document the course of the disease and treatment, including the collection of additional blood samples, take place 3 and 7 days after study enrollment. Twenty-eight days after enrollment, the patient's health status, treatment course, and complications are assessed by telephone. Finally, after 180 days, a telephone survey is conducted to determine the patient's whereabouts and survival status. Apart from the collection of biomaterials, no interventions are required or planned; physicians treat their patients as they normally would.

The main objective of this study is to investigate prevalence and risk factors for community-acquired pneumonia (CAP) and its interaction with comorbidities in an unselected group of adult patients receiving outpatient and inpatient care. In addition, information on HIV as a risk factor for CAP and on CAP in immunocompromised patients is collected.

Questions about this trial
What is this clinical trial studying?
An observational study of Community Acquired Pneumonia, run by Capnetz Stiftung at 1 site in Germany.
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 2 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: looking for participants now, as of the sponsor's last update on 5 May 2026. 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 Germany. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Frank Eberhardt (+49-511-532-5927, office@capnetz.de), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
diagnosis (time frame: 2 weeks). The study lists 3 primary outcomes in all. 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 NCT02139163, which also lists 16 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.
