A Long-term Observational Study Evaluating the Presentation and Management of Acute Respiratory Tract Infections in Primary Care Across Europe

Recruiting now

Conditions studied: Acute Respiratory Tract Infection

In brief

Acute respiratory infection (ARI) is the commonest reason for consulting in community care. Furthermore, new and re-emerging pathogens are often first noticed in primary care (PC). The POS-ARI-PC study is a long-term study, with the aim of describing the nature of ARI in adults and children presenting to PC across Europe. The POS-ARI-PC study will provide critically important data on the presentation and management of ARI, and build a research-ready infrastructure for studies related to the treatment, diagnosis, and prevention of ARI in primary care settings. Additional observational studies will be embedded and use the infrastructure developed in POS-ARI-PC.

Participant requires admission to hospital on the day of inclusion
Additional in/exclusion criteria might apply to embedded studies and will be described in the SSA or ISA.
POS-ARI-PC-001:
Symptoms and Duration Symptoms suggestive of an acute lower RTI with new or increased cough as the predominant symptom, with illness duration ≤10 days; AND/OR Symptoms suggestive of an acute upper RTI with sore throat and/or coryza as the predominant symptom, with illness duration ≤10 days;
Age Aged 60 years and over OR Aged 50 to 59 years and have a long-term health condition which makes them eligible for the yearly influenza vaccination under the national influenza vaccination programme;
