Brief Summary
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.

Outcome Measures
Primary Outcomes (13)
Age Bands
Participant age recorded at baseline by site study team.
Baseline (Day 0)
The proportion with a preliminary diagnosis of various sub-categories of ARI (e.g. LRTI, URTI)
Working diagnosis recorded at baseline by site study team.
Baseline (Day 0)
Overall illness severity rating
Overall illness severity (clinician's impression) recorded at baseline (mild, moderate or severe) by site study team.
Baseline (Day 0)
Swab samples taken and retrospective viral/microbiological infection analysis performed (multiplex PCR) to identify potential causative pathogens.
Participants have a combined oropharyngeal and nasal swab taken at the baseline visit which will be subjected to PCR-based analysis to identify potential causative pathogens.
Baseline (Day 0)
Proportion undergoing POC (with results) and lab-based investigations
POC investigations recorded at baseline and results recorded at day 28 by site study team.
Baseline (Day 0) and day 28.
Details of prescriptions given on presentation of ARI
Prescriptions given at presentation recorded at Baseline by site study team.
Baseline (Day 0)
Details of tests ordered on presentation of ARI
Tests ordered at presentation recorded at Baseline by site study team.
Baseline (Day 0)
Return to usual daily activities
Participants asked if they have returned to usual activities in daily diary.
Day 1-14
Feeling recovered from RTI
Participants asked if they are feeling recovered from RTI in daily diary.
Day 1-14
Use of prescription medication
Participants asked if they have used prescription medication for the RTI in daily diary.
Day 1-14
Use of over the counter medications
Participants asked if they have used over the counter medication for the RTI in daily diary.
Day 1-14
Complications reported associated to ARI presentation
Recorded at day 28 by a member of the site study team.
Day 28
Variation in practice and advice from national guidelines, to be fed back to national teams
Practice and advise recorded at Baseline by site study team.
Baseline (Day 0)
Secondary Outcomes (4)
Recommendations on how to improve study processes, recruitment and study communication based on shared understanding and insights from researchers, clinicians, and patients.
After day 28
An understanding of the meaning of study results for European primary care, from the perspectives of clinicians and patients, and recommendations regarding the implementation of findings.
After day 28
An understanding of changing health-seeking behaviour, management and expectations to inform clinical studies and trials
After day 28
Approval for a study-specific appendix (SSA) or an intervention-specific appendix (ISA) of an embedded (non) randomised study for ARI in primary care associated with this POS, measured using the number of embedded studies to this POS-ARI-PC platform over

Study Arms (1)
POS-ARI-PC
POS-ARI-PC AUDIT: Anonymous registration of patients of any age presenting at the participating primary care facility with ARI. POS-ARI-PC CORE: Patients of any age presenting at the participating primary care facility with ARI. POS-ARI-PC-001: Patients 60 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, presenting at the participating primary care facility with ARI.
Eligibility Criteria
Patients of any age group presenting to primary care settings with an ARI.
You may qualify if:
- Eligible patients will be of any age consulting (telephone, video, face-to-face) with a participating health care facility with:
- Symptoms suggestive of an acute lower RTI with cough as predominant symptom and with illness duration less than 28 days, AND/OR
- Symptoms suggestive of an acute upper RTI with sore throat and/or coryza as predominant symptom and with illness duration of less than 14 days AND/OR
- Patients otherwise suspected of COVID-19, influenza or RSV.
You may not qualify if:
- Patients will not be eligible for if they have withdrawn their consent for anonymous data collection for research by their health care facility.
- POS-ARI-PC CORE:
- Eligible patients will be of any age consulting (telephone, video, face to face) with a participating primary health care facility with:
- Symptoms suggestive of an acute lower respiratory infection with cough as the predominant symptom, with illness duration less than 28 days, AND/OR
- Symptoms suggestive of an acute upper respiratory infection with sore throat and/or coryza as the predominant symptom, with illness duration of less than 14 days AND/OR
- Other symptoms suggestive of COVID-19, Influenza, RSV AND
- Participant or legal guardian(s) willing and able to provide informed consent and comply with study procedures
- Patients will not be eligible if:
- According to the judgement of the recruiting clinician, they will not be able comply with study procedures, for example because they do not understand the language in which the study is being conducted locally (and have no one to help and translate for them); have a serious psychiatric disorder; or are terminally ill
- Symptoms of presumed non-infective origin
- 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;
- Consent Willing and able to provide informed consent and have a swab taken.
- As per the POS-ARI-PC CORE Protocol, with one exception: patients needing hospitalisation can be recruited into the study if timing allows. Patients can provide a swab and decide not to participate in the follow-up procedures.
