CRP and Lung Ultrasound in Respiratory Evaluation

Sponsor: Fundacio d'Investigacio en Atencio Primaria Jordi Gol i Gurina

Summary

Lower respiratory tract infections (LRTIs) are one of the most common reasons for consultation in Primary Care centres. Differentiating between viral and bacterial aetiologies can be challenging, leading to inappropriate antibiotic prescribing. Lung ultrasound (LUS), an imaging test that gained particular relevance since the beginning of the SARS-CoV-2 pandemic, offers several advantages over the classic chest X-ray in detecting and monitoring LRTIs, especially when pleural involvement exists. This study aims to correlate LUS findings with capillary blood C-Reactive Protein (CRP) values in patients with LRTIs, evaluating LUS as a diagnostic tool and its impact on therapeutic decisions. The descriptive observational study, conducted from January 2024 to December 2026 in Lleida, will include LRTI patients attending Primary Care centres. By validating LUS as a rapid and non-invasive diagnostic tool, unnecessary antibiotic prescriptions can be reduced, promoting LUS as a complementary test in Primary Care consultations. This will facilitate appropriate diagnosis and treatment decisions for patients with LRTIs, enhancing the overall management of respiratory infections.
