<![CDATA[Pneumonia is an infectious disease that causes acute inflammation of the lung parenchyma and compaction exudate in the lung tissue. In addition to causing significant morbidity and mortality, pneumonia is also difficult to diagnose, treatments are less precise and less taken seriously. Pneumonia caused the death of 14% of children under five in Indonesia, with a mortality rate of 83 children per day. The difficulty of diagnosis, the selection of a less appropriate antibiotics, side effects, differences in pharmacokinetics and pharmacodynamics of the drug in infants and antibiotics resistance is to be a problem in itself. Therefore it is necessary to study the analysis of the use of antibiotics in patients with pneumonia of children aged 3 months till 5 years. The aim of this research to analyze antibiotics therapy in patients with pneumonia of children aged 3 months till 5 years. Method: an observational cohort analysis was carried out in the Pediatrics Respirology Division Dr. Soetomo Hospital Surabaya. Data was collected from February to May 2014. Patients who met the inclusion criteria were observed prospectively and the quantity and quality of antibiotics usage assessed with Gyssens category.
