N2 - Introduction: The incidence of chronic kidney disease (CKD) is growing rapidly, along with the increasing geriatric population. CKD patients have higher incidence of fractures, stroke, and hospitalizations requiring rehabilitation. This is accompanied with the need for suitable rehabilitation programs to decrease disability and improve functionality to help elderly CKD patients maintain independence in activities of daily living. Considering that survivors of acute kidney injury (AKI) tend to experience decreased quality of life with increased frailty, rehabilitation in the elderly with kidney injury becomes even more complex. The aim of this study was to examine the impact of AKI on the outcomes of rehabilitation among elderly patients with CKD. Methods: For this retrospective, observational study, the electronic medical records of all patients who were hospitalized in the rehabilitation department were reviewed. We assessed functional status at the beginning and end of rehabilitation, renal outcome, and all-cause mortality among elderly patients with CKD who experienced an AKI and compared them to those who did not have an AKI. Results: The study cohort included 183 elderly patients with non-dialysis-dependent CKD. Patients with AKI (23% of study cohort) had a higher prevalence of heart failure and lower baseline estimated glomerular filtration rate, as compared with patients who did not have AKI. They were admitted to rehabilitation at a poorer functional capacity and were also discharged with lower functional independence measure scores. Overall odds ratio for all-cause death among patients with AKI versus without AKI was 3.2 (95% CI: 1.6-6.5; p = 0.001). Conclusion: AKI and CKD are interrelated syndromes. AKI was prevalent among elderly CKD patients and was associated with worse rehabilitation outcomes and higher mortality compared to similar patients without AKI.
