Survival analysis and prognostic factors of chronic kidney disease: A case study in Batna, Algeria

Introduction: Chronic kidney disease (CKD) was qualified as one of major public health issues in Algeria, and the study of risk factors for this disease is of great importance. Methods: Data of 247 followed up patients were recorded over the period (1987-2017) in the province of Batna in Algeria, and parametric regression models (Exponential and Weibull) were fitted to estimate survival functions by adjusting different prognostic factors. Results: The findings revealed that there was a minor difference between men and women in terms of survival time, for a short follow-up period, there was no difference in survival between smokers and non-smokers, but in the long term, such a difference was revealed.  75% of the deaths had an initial disease: diabetic or hypertensive nephropathy, and when adjusting this covariate into the models, women recorded a higher risk of death (thus low survival time) compared to men. Conclusion: These results should be taken into consideration to enhance more the national health strategy of kidney disease.
