Individuals with diabetes often develop other diabetes-related health problems. Seven health problems are currently tracked by the NDSS: hypertension, ischemic heart disease, heart attack (acute myocardial infarction), heart failure, chronic kidney disease, stroke (cerebrovascular disease) and lower limb amputations. All but hypertension are tracked using hospitalization data.
People with diabetes may not always be hospitalized with these health problems, leading to underestimates. Therefore, the NDSS tracked hypertension and plans to track other health problems using physician billing and hospitalizations, similar to the method used to track diabetes.
The case criteria for hypertension were one or more hospitalizations or 2 or more physician claims within 2 years for hypertension.
|Other Health Problems||Rate Ratios||Adults with Diabetes Hospitalized with Other Health Problems||Proportion (%) of All Adults with Diabetes|
|Ischaemic Heart Disease||3.5||93,691||4.5|
|Heart Attack4 (Acute Myocardial Infarction)||3.3||26,895||1.3|
|Chronic Kidney Disease||6.5||40,341||2.0|
|Stroke (Cerebrovascular Disease)||2.7||23,912||1.2|
|Lower Limb Amputations||18.6||3,001||0.2|
|Individuals With Diagnosed Diabetes||2,061,995||100.0|

1 Data were rate ratios of age-standardized rates. Data from Quebec were not available for the rate ratio statistics, but were included in the number of adults with diabetes who had other health problems.
2 Other Health Problems were: ischemic heart disease, heart attack (acute myocardial infarction) heart failure (myocardial infarction), chronic kidney disease, stroke (cebrovascular) and lower limb amputations A person with diabetes hospitalized with more than one health problem was counted once in each category.
3 Data from Nunavut were unavailable.
4 When more than one hospitalization is recorded in the heart attack category, an individual with diagnosed diabetes is counted only once under the broader ischemic heart disease category.
1 Data from Quebec were not available for the rate ratio statistic but were estimated for the number of adults with hypertension.
2 Data from Quebec were not available for the rate ratio statistics, but were included in the number of adults with diabetes who also had other health problems.
