The Nephrology chapter of the RCEM curriculum focuses on recognising and managing acute and life-threatening renal disorders that commonly present to the Emergency Department. For MRCEM SBA preparation, this topic is particularly important because renal dysfunction often underpins multiple emergency presentations — from electrolyte imbalance and acid–base disturbance to acute kidney injury, sepsis, shock, and toxic ingestion.
A strong understanding of renal physiology, fluid balance, and renal replacement therapy (RRT) is essential for interpreting laboratory results quickly and initiating timely management. SBAs frequently test the ability to identify when to refer for dialysis, manage AKI, and avoid iatrogenic harm through safe prescribing and fluid therapy.
In short, Nephrology integrates critical decision-making, physiology, and practical emergency management — making it a high-yield system for the MRCEM SBA exam and an indispensable skill set for any emergency physician.
