Abstract

The aim of this work is to study the epidemiological aspects of pneumonia and identify the risk factors for incidence rate of pneumonia among children aged 0-5 years treated as in-patients, at Irrua Specialist Teaching Hospital, Edo State, Nigeria. Adopting survival analysis technique, the number of patients that survived or remained after intervention over a period of time with the Kaplan-Meier estimator was computed and curves of survival probabilities were plotted. Statistical difference among the sex of the in-patients were compared and checked using the Log-rank test. Results obtained from the survival distribution reveal that as the number of days (time) increases, the chances of survival decline rapidly with a p – value of 0.03. The study shows that at 70.8 days, the chance of survival was 0.95 but as the days increased to 197.1 the chances of survival declined rapidly to 0.5. Mortality trend from the result also indicates that survival probabilities declined with the passage of time, and that the mean survival rate of male infants is higher than that of females
