Back to the Basics: Community-Acquired Pneumonia in Children

Community-acquired pneumonia (CAP) is a common childhood infection and often a reason for inpatient admission, especially when a child is hypoxic or in respiratory distress. Despite advances in technology and diagnostics, it remains difficult to accurately differentiate bacterial CAP from a viral process. Most of the laboratory tests routinely done in inpatient medicine, such as complete blood counts and acute phase reactants, do little to differentiate a viral pneumonia from a bacterial pneumonia. Clinicians must rely heavily on the clinical presentation and decide whether to treat empirically with antibiotics. Guidelines published by the Infectious Disease Society of America in 2011 have helped clinicians standardize the diagnosis and treatment of CAP. The guidelines recommend relatively narrow-spectrum antibiotics, such as ampicillin or penicillin, as empiric coverage for the fully immunized child older than age 3 months who requires hospitalization for CAP.
