title: Managing CAP patients at risk of clinical failure.
abstract: Community-acquired pneumonia (CAP) is a curable disease. Both the European and American clinical practice guidelines provide algorithms how to manage patients with CAP. However, as populations worldwide are ageing and bacteria are becoming multidrug resistant, it is necessary to address the major factors that put patients at risk of poor outcome. These may include age, comorbidities, the settings where pneumonia was acquired or treated, the need for hospitalisation or ICU admission, likely causative pathogen (bacteria or virus) in a certain region and their local susceptibility pattern. One complicating fact is the lack of definite causative pathogen in approximately 50% of patients making it difficult to choose the most appropriate antibiotic treatment. When risk factors are present simultaneously in patients, fewer treatment options could be rather challenging for physicians. For example, the presence of comorbidities (renal, cardiac, hepatic) may exclude certain antibiotics due to potential adverse events. Assessing the severity of the disease and monitoring biomarkers, however, could help physicians to estimate patient prognosis once diagnosis is confirmed and treatment has been initiated. This review article addresses the most important risk factors of poor outcome in CAP patients.
