Comments Detailed
Further information on the methodology used to generate a diabetes chronic disease cohort from which diabetic patients in this measure are drawn: The algorithm to identify patients with diabetes links different databases at ICES and is based on having two physician claims with a diagnostic code for diabetes (Dx Code 250) or one OHIP fee code for diabetes management, insulin therapy support, diabetic management assessment codes claim (Q040, K029, K030, K045, K046) or one hospitalisation with a diagnostic code of diabetes within 2 years. Gestational diabetes is excluded from this definition based on the following algorithm: Whenever there was a hospital record with a diagnosis of pregnancy care or delivery between 120 days before and 180 days after a gestational admission date, the diabetic record was considered to be for gestational diabetes, and it was excluded. The administrative data case-definition algorithm for diabetes has a sensitivity of 86% and specificity of 97%.5
