Premature mortality in an administrative cohort of individuals living with type 2 diabetes screened for chronic kidney disease in Jalisco, Mexico 2011-2019. Evidence from a death registry analysis. Supplementary material

This document contains the supplementary material for the article titled “Premature mortality in an administrative cohort of individuals living with type 2 diabetes screened for chronic kidney disease in Jalisco, Mexico 2011-2019. Evidence from a death registry analysis”, accepted for publication in the Journal Salud Pública de México. This study aims to analyze survival outcomes and describe clinical and demographic characteristics linked to premature mortality in an uninsured population with type 2 diabetes (T2D) screened for chronic kidney disease (CKD). Our objective is to demonstrate the need for protocolized interventions for early detection, treatment, and follow-up of CKD in high-risk populations. We designed an administrative cohort by linking mortality records with data from a CKD screening campaign using a probabilistic linkage algorithm. The supplementary material shared here is divided into three sections: Section 1 describes the procedures used in an early CKD detection campaign, from which we obtained the database we have named T2D-CKD database in our study. Section 2 describes Cox proportional hazards models specification. We used these models to analyze the associations between clinical and demographic characteristics at screening as covariates, and all-cause, CKD-related, and all-cause premature mortality as outcome variables. In Section 3, we provide a supplementary table titles Clinical and demographic characteristics associated with survival in a T2D population screened for CKD. Unadjusted and adjusted Cox proportional hazards models.
