BACKGROUND: Several predictive scoring systems have been developed to improve the clinical management of patients with community-acquired pneumonia (CAP) and optimise resource allocation. None of the current scores have been validated for immunosuppressed patients and data on outcome of CAP in solid organ transplant recipients are scarce. What is the predictive value of pneumonia severity scores in solid organ transplant recipients with CAP?

We assessed clinical outcomes and evaluated six risk scores (CRB-65 (confusion, respiratory frequency
