Using linked administrative data to study periprocedural mortality in obesity and chronic kidney disease (CKD)

Abstract

Both obesity and chronic kidney disease (CKD) are associated with adverse periprocedural outcomes, but it is unknown how these two common conditions interact to influence risk. We examined the feasibility of combining a new procedurerelated, obesity-specific flag with administrative and laboratorydata and assessed the joint association between obesity and CKD with mortality. Since 2007, Alberta physicians may claim a fee supplement for performing eligible surgical and non-surgical procedures on patients with documented BMI ≥ 35 kg/m2. to study obesity-related outcomes. Results from the linked dataset demonstrated face validity-subjects with both obesity and CKD were at increased risk of periprocedural mortality, and this was driven in part by differences in age and comorbidity. © The Author 2013.
