摘要

A study of survival rate of TB patients was carried out using secondary data extracted from 85 Tb patients’ records from January 2013 to December 2014 in the Upper West region of Ghana. The Cox Proportional Hazard Model was used to determine the components of the model. Apart from the time to event such as death, each Tb patient had a number of risk factors (covariates) which affected either survival or mortality. The study sought to determine the effect of three factors or covariates on survivorship. The baseline was determined as; a female aged between 0-24 years, who had negative smear TB and was tested negative for HIV and had not started TB treatment. Of all the covariates, TB/HIV co-infection was found to be the most influential covariate or factor that affected the hazard rate or force of mortality. In contrast, Tb treatment was observed to have had significant influence on survivorship. The Cox model therefore provided an estimate of the relative level of an individual’s survivorship in relation to the baseline. Mortality or survival differences occurred as a result of each patient’s predisposing factors such as sex, age, type of TB, co-infection with HIV amongst others.
