The CHOIR and CREATE studies led to changes in hemoglobin targets around the world for patients with chronic kidney disease. The aim of this study was to determine what effect these pivotal studies had on hemoglobin levels and survival Data were extracted from Australia's Renal Anaemia Database for patients with chronic kidney disease between October 2000 and December 2009. Survival was significantly longer in patients with chronic kidney disease who died between 2007 and 2009 compared to those who died between 2000 and 2006.
