Survival analysis to analyze factor that affect the rate of recovery patients of pneumonia

Abstract

This study aims to apply survival analysis for the survival of patients diagnosed with Pneumonia and to identify the factor that affects the rate of recovery of Pneumonia patients in the treatment period. The data used in this study is the patients’ initial time when they were entering the hospital until they were experiencing an event that is when the patients have been declared cured of the disease. This study is an applied research with a causal-comparative approach by observing data from the factor that was suspected as the cause, as a comparison to investigate the possibility of causation. After that, an analysis was done by using Cox regression model in the case and its application to know the factor that can affect the level of healing Pneumonia patients at PKU Muhammadiyah Bantul Hospital; as the duration of therapy in the hospital is the time of survival. In accordance with the Anderson Darling distribution test, the result of the patient’s survival time distribution test is a normal distribution with Box-Cox Transformation. The result shows that the respiration rate affects the recovery rate of Pneumonia patients with the coefficient value is-0.04082.
