Study population: children with community-acquired pneumonia presenting to the Children's Hospital of Eastern Ontario emergency department

Brief summary: Pneumonia, or lung infection, is usually treated with antibiotics targeted against the organisms that the physician guesses are causing the problem. The determination of the exact cause of a patient's pneumonia is difficult. The problem is that the two major causes of community-acquired pneumonia are not easily distinguished on clinical grounds and are best treated by different antibiotics. The investigators hypothesize that antibiotic therapy can be targeted and improved by doing polymerase chain reaction (PCR) testing of nose swabs to identify probable implicated organisms and their antibiotic resistance patterns. This pilot study will be important to ensure that the laboratory testing is functional and that the emergency department-laboratory communication is optimal prior to doing a full-fledged randomized clinical trial.
