Report from the National Diabetes Surveillance System: Diabetes in Canada, 2008

Other Health Problems11

Eight heath problems, for which hospitalizations are common among individuals with diagnosed diabetes, are currently tracked by the NDSS. They are chronic kidney disease, lower limb amputations, and cardiovascular disease - which includes but is not limited to: hypertensive disease, heart failure, heart attack, ischaemic heart disease, and stroke.

For Adults Aged 20 Years and Older:

  • In 2005-2006, the most common health problem seen in hospitalizations among individuals with diagnosed diabetes was for cardiovascular disease (about 9%). (Table 3)
  • During 2005-2006, adults, aged 20 years and older, with diagnosed diabetes were hospitalized more often than their counterparts without diagnosed diabetes: (Table 3)
    • 23 times more often with lower limb amputations;
    • 7 times more often with chronic kidney disease;
    • 3 times more often with all cardiovascular diseases;
      • 4 times more often with hypertensive disease and heart failure and,
      • 3 times more often with heart attack, ischaemic heart disease, and stroke.

*Select comorbid conditions were for the following: cardiovascular disease, hypertensive disease, ischaemic heart disease, acute myocardial infarction, heart failure, cerebrovascular
disease, chronic kidney disease, and lower limb amputations. An individual may have more than one comorbid hospitalization, and is only counted once in each category.

**Data are rate ratios of age-standardized rates. Rates are age-standardized to the 1991 Canadian population.

^Quebec data were excluded from analysis and data from Nunavut were unavailable.

When more than one hospitalization is recorded in one of the highlighted cardiovascular disease categories: hypertensive disease, ischaemic heart disease, acute myocardial
infarction, heart failure, or cerebrovascular disease, an individual with diagnosed diabetes is counted only once under this broader cardiovascular disease category.

Lower limb amputations exlcude those caused by trauma or cancer.
