Acute Kidney Injury in Medical Admissions at Federal Medical Centre, Azare, Bauchi State, North East Nigeria

Acute kidney injury is a frequently encountered and high-mortality complication in general medical admissions in Nigeria, and its early recognition and management in secondary and federal medical centres in North East states are constrained by limited biochemistry laboratory turnaround times and intensive care capacity. This study examines the incidence, aetiology, and clinical outcomes of acute kidney injury among adult medical admissions at the Federal Medical Centre, Azare, Bauchi State. A prospective cross-sectional design is applied over an eight-month study period, enrolling all adult medical admissions meeting KDIGO criteria for acute kidney injury through serial serum creatinine monitoring. Data include admission diagnosis, AKI stage at peak, presumed aetiology, fluid management, dialysis requirement, renal recovery at discharge, and 30-day mortality. SPSS is used for analysis. Available renal medicine literature from North East Nigeria identifies sepsis, malaria-related acute kidney injury, and volume depletion from gastroenteritis as the leading causes, with stage 3 AKI carrying an in-hospital mortality exceeding 40 percent in the absence of dialysis. The KDIGO Clinical Practice Guidelines for AKI provide the diagnostic and staging framework. Findings will support advocacy for peritoneal dialysis infrastructure procurement and protocol standardisation at the centre.
