It was 1:15 p.m. when Professor Sisay Ade, identified by a pseudonym, received a call from Mbale Regional Hospital that his sister, Kofi, also a pseudonym, 58, had gone into cardiac arrest. With a history of end-stage renal failure and diabetes, Kofi had checked into the Msaba Wing that morning to undergo routine dialysis treatment. Thirty minutes later, her heart abruptly ceased to function.
