Working group summary of the 2023 full update of the Finnish national guidelines for paediatric lower respiratory tract infections

The first evidence-based Finnish guidelines for paediatric lower respiratory tract infections (LRTIs) were published in 2014 and completely updated in 2023. This paper, by the interdisciplinary working group that developed the 2023 guidelines, summarises the main recommendations. The 2023 guidelines were produced after a systematic review. Strong evidence was at least two separate, high-quality studies, moderate evidence was at least one high-quality study and weak evidence was at least one satisfactory study. The authors have now summarised the key points. There was strong evidence that antitussives and beta-sympathomimetics were not effective for bronchitis-related cough and that laryngitis should be treated with oral corticosteroids, with adrenaline inhalations added in severe cases. Also, that amoxicillin for 5 days provided sufficient treatment for paediatric community-acquired pneumonia and that children with apparent viral pneumonia could be observed without antimicrobial therapy. There was moderate evidence that corticosteroids or inhaled agents were not effective for bronchiolitis and that administering salbutamol with a holding chamber could relieve symptoms of wheezing bronchitis. Also, pertussis should be considered for unvaccinated infants with coughs. The 2023 guidelines aim to improve acute evidence-based treatment of LRTIs, through appropriate antibiotics, inhaled drugs, corticosteroids, radiology and laboratory testing.
