Procalcitonin and Lung Ultrasonography Point-of-care Testing to Decide on Antibiotic Prescription in Patients With Lower Respiratory Tract Infection at Primary Care Level: Pragmatic Cluster Randomized Trial
Procalcitonin and Lung Ultrasonography Point-of-care Testing to Decide on Antibiotic Prescription in Patients With Lower Respiratory Tract Infection at Primary Care Level: Pragmatic Cluster Randomized Trial
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
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.
All patients presenting to a participating GP's office for a consultation for an acute respiratory infection (ARI) will be screened for inclusion in the study
