Overview
Brief Summary
The study is randomized clustered pragmatic trial whose objective is to decrease unnecessary antibiotic prescription in adult patients with lower respiratory tract infection managed at primary care level in Switzerland, using a simple algorithm based on 2 point of care test results
Detailed Description
The study will have two distinct phases: The first phase will test the feasibility of the intervention (UltraPro) along a pilot study. Following the setup of a lung ultrasound training curriculum for general practitioners, the practicality of the whole UltraPro algorithm will be evaluated at primary care level. The second phase will be a pragmatic randomized three-arm intervention study using an algorithm based on the results of procalcitonin and lung ultrasound to manage patients with lower respiratory tract infections at primary care level. The procalcitonin-ultrasound algorithm will be compared to procalcitonin-guided management alone and usual care.

Outcomes
Primary Outcomes
Proportion of patients prescribed an antibiotic in each arm
Time Frame: Assessed at day 28 after baseline
For each arm, we will assess the proportion of patient's prescribed an antibiotic following the consultation with the general practitioner. This will be done by recording the prescription decision of the general practitioner.
Secondary Outcomes
- Serious adverse outcome(During the first 28 days following baseline)
- Duration of algorithm completion(Assessed at baseline (Day 0))
- Aetiology of LRTIs in primary care(Assessed within the first year after data collection is complete)
- Duration of the episode(Assessed at day 28 after baseline)
- Transcription patterns(Assessed within the first year after data collection is complete)
- Host biomarkers(Assessed within the first year after data collection is complete)
- Clinical failure(Day 7 after baseline)
- Cost / effectiveness ratio(Assessed one month after data collection is complete)
- Number of medical visits(Day 7 and Day 28 after baseline)
- Satisfaction of providers(Assessed at baseline)
- Satisfaction of patients(Assessed at day 7)
