Background: Pediatric respiratory disease remains an important cause of morbidity in both the developing and the developed world. Aim of the study is to validate Acute Illness Observation Scale (AIOS) in predicting illness severity and clinical outcome of community acquired pneumonia.

Methods: This was a descriptive study done in a cohort of 248 children at the Department of Paediatrics, at a tertiary care hospital in Chennai. Children between 2 months - 59 months coming to outpatient department with suspected pneumonia, if satisfying the inclusion criteria were enrolled into the study. AIOS scoring is done on each subject on day 1, day 2, day 5 by two persons simultaneously in a reasonably quite state. Respiratory parameters, vital signs and pulseoximeter reading of each patient as in data collection form are documented.

Results: Children scoring abnormally on AIOS (>10) had significantly higher frequency of severe tachypnea (p=0.001), marked chest retraction (p=0.001), grunting, cyanosis (p=0.01), lethargy, inability to drink and so on except incidence of convulsion and wheeze which didn’t have any statistical significance. Severe hypoxemia associated with cyanosis (SpO2<85) was observed in 14 children of which 92.9% (13) scored a high value on AIOS (AIOS>15). Complications were absent in those who scored <10, while maximum complications were seen in those who scored >15.

Conclusions: AIOS can be used as a tool to decide on therapeutic modalities and prognosticating a child with pneumonia admitted to the hospital by a physician.
