Hospital-acquired pneumonia is a serious and potentially life-threatening complication, with reported pneumonia-attributable mortality rates as high as 50%. Rapid diagnosis and immediate institution of adequate empirical antimicrobial treatment are of paramount importance in patient management.

Should this now become a part of patient management?
