Acute Renal Failure in the Elderly, over the Age of 75, in the Medical and Rehabilitation Hospital of Saint-Maurice (Paris - France)

Abstract

Introduction: Acute renal failure (ARF) in the elderly is a common occurrence and will increase because of the aging population. Even though the elderly can develop any type of ARF, they are more exposed to iatrogenic ones due to polymedication. Objective: To determine the frequency of the ARF in the elderly over 75, and evaluate its impact on mortality. Methods: This is a retrospective study conducted in 2011 at the medical and Rehabilitation Hospital of Saint- Maurice. Were included, all patients aged 75 and over with an ARF, hospitalized during the study period. Results: Fifty-six patients of which 23 men (41%) and 33 women (59%) were included from a total of 209 patients; a frequency of 26.8%. The mean age was of 86.5 ± 6 years. The mean creatinine clearance level was of 17.2 ± 40.8 ml/min (MDRD). Twenty-eight of our patients were on diuretics i.e. 50%. The average hospital stay was of 78 days in patients with ARF against 33 days in those who did not have ARF. We recorded 8 deaths, including six in those with acute renal failure (10.7%). Conclusion: Acute renal failure in the elderly is a common disease that is a common morbid event. Prevention relies on the preservation of the extracellular volume and should be a marker for quality health care.
