Pneumonia is defined as an infection of the lung tissue in which the air sacs become filled with microorganisms, fluid and inflammatory cells, affecting the function of the lungs (National Institute for Health and Care Excellence [NICE], 2021a). The disease can affect anyone at any age and is a cause of morbidity mortality around the world, and particularly likely to result in poor outcomes in the elderly, babies and young children, and those with additional health problems (Htun et al, 2019). This article focuses on community-acquired pneumonia (CAP) in adults, and hopes to give nurses and non-medical prescribers an insight into the recognition, treatment and management of this disease in the adult population, with the aim of reducing hospital admissions and improving outcomes for those patients affected.
