Resource Use and Outcomes in Patients with Dialysis Dependent Chronic Kidney Disease Admitted to Intensive Care.

Abstract

Central Australia (CA) has a high prevalence of haemodialysis-dependent-chronic kidney-disease (CKD5D). CKD5D is associated with an increased need for critical care services. To describe the demographic features, critical care resource use, and outcomes of patients with CKD5D requiring intensive care admission in CA. Retrospective matched cohort database study. Patients with CKD5D who required admission for critical illness between 1 July 2015 and 30 June 2016 were identified using the Centre for Outcome and Resource Evaluation Outcome Measurement and Evaluation Tool (CORE COMET) and matched with patients without CKD5D. The primary outcome was all cause mortality. Secondary outcomes explored use of critical care and other ongoing health-care use. There were 621 critical care admissions during the study period. Of these, CKD5D patients comprised 88 admissions (14%), representing 63 patients. Compared to matched controls, these patients had a similar mortality at a median followup of 463 days (17% Vs 22%, p = 0.50) which did not change when patients with an ICU length of stay (LoS) less than 4 days were excluded. CKD5D patients had a shorter median ICU LoS (1.3 Vs 2.9). Although those with CKD5D had higher health-care resource use, the rate of utilisation remained unchanged by their ICU admission. This retrospective observational matched cohort study examining the burden of disease amongst CKD5D patients in CA suggests that there is no additional mortality burden in this group, nor do they require significantly higher critical care resources compared to a matched cohort.
