Abstract
Category: Epidemiology and Outcomes from AKI Presenter: Dr LAILATULEMA ABBAS Keywords: hospital acquired acute kidney injury, incidence Acute kidney injury in hospitalized patients is associated with significant morbidity and mortality. The spectrum of hospital acquired acute kidney injury (HA-AKI) ranges from asymptomatic to a completely anuric state. Advanced age group postulated to be a probable risk factor for AKI during hospitalization. To study the HA-AKI incidence and outcome of HA-AKI in geriatric patients admitted to a district hospital. An observational study of HA-AKI patients admitted to general medical wards from 1stNovember 2016 to 31st December 2016 was conducted. All geriatric patients aged more than 65 years old were included. According to Kidney Disease: Improving Global Outline (KDIGO), HA-AKI was defined as raised in serum creatinine of more than 26μmol/L 48 hours after hospitalization. Medical records were reviewed retrospectively. Incidence: There were 1319 admissions during the study period. Six patients excluded from the dataset due to missing medical records. Only 45 HA-AKI cases were included. The incidence of HAAKI were 3.4% (n= 45). Patients were 25 (55.6%) male, and 20 (44.4%) female. The mean age was 58.7 ± 16.9 years, whereas average length of stay was 9.1 ± 6.8 days. The commonest cause of HA-AKI observed were sepsis 21 (46.7%) cases, acute coronary syndrome 6 (13.3%) cases and vascular-related disease 6 (13.3%) cases. While most patients had diabetes, only 3 (6.6%) patients had background of chronic kidney disease (CKD). Geriatric Outcome: There were 20 (44.4%) geriatric patients identified. Two (18.2%) patients had complete recovery of renal function while 9 (81.8%) patients progressed to CKD. However, 9 (45%) patients succumbed to the illness during admission. Only 1 (5%) patient had renal replacement therapy done during the course of hospitalization. Geriatric patients with HA-AKI has risk of developing CKD upon discharge therefore prevention and management strategies for this condition need to be identified to limit the risks of susceptible patients.
