High unchanged incidence of diabetic ketoacidosis between 2000 and 2009 in Auckland children

Methods Data from Auckland children with newly diagnosed T1DM between 1 January 2000 and 31 December 2009 were collected from Starbase, the Starship Children’s Hospital diabetes database. T1DM was confirmed by the presence of glutamic acid decarboxylase and/or tyrosime phosphatise-like protein (IA2) antibodies. DKA was defined by international criteria as venous or capillary pH and bicarbonate as mild DKA with pH <7.30 and bicarbonate <15 mmol/l, moderate DKA pH <7.20 and bicarbonate <10 mmol/l and severe DKA ph <7.10 and bicarbonate <5 mmol/l.
