Adjustment (risk, age/sex standardization)- detailed
This data is unadjusted. Unadjusted data reports the physician’s actual practice data. This is useful for comparing one’s own data over time.

Comments Detailed
A patient is said to have hypertension if they have 2 physician billing claims or 1 hospital discharge with a diagnosis of hypertension in a 2-year period that had the following ICD 9 codes: 401.x, 402.x, 403.x, 404.x, or 405.x or the following ICD 10 codes: I10.x, I11.x, I12.x, I13.x, or I15.x
Further information on how this cohort was generated: The case-definition algorithm to identify patients with hypertension links the Discharge Abstract Database (DAD) and the Ontario Health Insurance Plan (OHIP). Hypertension is said to be present if an individual had one hospital admission with a hypertension diagnosis (CIHI ICD-9 dxcodes: 401x, 402x, 403x, 404x, or 405x; CIHI ICD-10 dx10codes: I10, I11, I12, I13, or I15), or an OHIP claim with a hypertension diagnosis (OHIP dxcodes: 401, 402, 403, 404, or 405) followed within two years by either an OHIP claim or a hospital admission with a hypertension diagnosis. The administrative data case-definition algorithm has a sensitivity of 72%, specificity of 95%, positive predictive value of 87% and negative predictive value of 87%.1
