Overview
Brief Summary
Antimicrobial resistance rates have reached alarming levels and the Worlds Health Organisation (WHO) states it constitutes a serious public health concern by threatening one of the most effective and mortality lowering interventions in modern medicine. Part of the solution to this problem includes minimizing overuse of antibiotics. But clinical signs alone are often not reliable to guide antibiotic treatment decisions and additional tests may be warranted to assist the doctor. Such tests include point-of-care biomarkers of infection like C-reactive protein (CRP) and procalcitonin (PCT). Targeting antibiotic use to the few patients with a high probability of benefit and withholding in the many with non-serious respiratory infection is a promising strategy and readily implemented in clinical practice.
The Procalcitonin guided Antibiotics in Respiratory Infections (PARI) study will assess the effect of a novel point-of-care PCT guided antibiotic stewardship in acute respiratory tract infections in general practice.
The overall aim of the PARI study is to reduce antibiotic use in patients with acute respiratory tract infections by targeting antibiotic treatment only to patients with a suspected bacterial etiology and thus likely to benefit from antibiotic therapy.
The main research questions are:
Does the addition of a point-of-care Procalcitonin test to standard care reduce antibiotic use in primary care? Is the intervention safe for the patients? The PARI study is a pragmatic two-arm (intervention and control (standard care) open randomized non-inferiority trial (up to 1 day difference in recovery) in general practice.

- •C-Reactive Protein \>20 mg/m
Exclusion Criteria

Outcomes
Primary Outcomes
Duration of illness and symptoms from acute respiratory tract infections.
Time Frame: up to 14 days
The patient reported primary outcome will be assessed as number of days to a patient's daily activities (work or recreation) are no longer restricted by symptoms from a respiratory tract infection.The non-inferiority margin between the intervention and control group is set at a one day difference. The recovery measure will be the specific day indicated by the participants using the validated Acute Respiratory Tract Infections Questionaire (ARTIQ).
Secondary Outcomes
- Antibiotic treatments(1, 14 and 30 days)
- Side effects from antibiotic treatment(14 days)
- re-consultations(30 days)
- Biomarker levels(day 1)
- Severe adverse effects(30 days)
