EXHIBIT A.

Diabetes prevalence per 100 adults in Ontario, by Local Health Integration Network (LHIN), on March 31, 2011

KEY FINDINGS

• Across Ontario’s 14 LHINs, the

average prevalence of diabetes in

March 2011 varied by as much as

1.5-fold, ranging from 8.44 to 12.

for every 100 adults.

• Diabetes prevalence was highest in

the Central West LHIN (5) at 12.39 for

every 100 adults. Higher-than-

average prevalence was also seen in

the Erie St. Clair, Central, Central

East, North East and North West

LHINs (1, 8, 9, 13 and 14).

Number, per 10,000 adults with diabetes, who had at least one hospitalization or emergency department visit for hyper- or hypoglycemia in Ontario,

KEY FINDINGS

• Between 2006/07 and 2010/11, the

number of adults, per 10,000 with

made emergency department visits

for hyper- or hypoglycemia varied by

as much as two-fold. The provincial

average was 486 per 10,000 adults

with diabetes.

• The highest rates were seen in LHINs

in southwestern, southeastern,

central and northern Ontario (2, 10,

12, 13 and 14).

Number, per 10,000 adults with diabetes, who had at least one hospitalization or emergency department visit for a skin and soft tissue infection or foot ulcer

in Ontario, by Local Health Integration Network (LHIN), 2006/07–2010/

KEY FINDINGS

• Between 2006/07 and 2010/11, the

number of adults, per 10,000 with

diabetes, who had at least one

hospitalization or emergency

department visit for a skin and soft

tissue infection or foot ulcer varied by

more than three-fold across Ontario.

The provincial average was 618 per

10,000 adults with diabetes.

• A markedly elevated rate was seen in

the North West LHIN (14): 1,308 per

10,000 adults with diabetes. Above-

average rates were also seen in the

other central and northern LHINs (

and 13) and in LHINs in southwestern

and southeastern Ontario (2 and 10).

KEY FINDINGS

• Among adults with diabetes, rates of

lower extremity amputations varied

by more than 3.5-fold across

Ontario’s 14 LHINs between 2006/

and 2010/11. The provincial average

was 74 per 10,000 adults with

diabetes.

• The highest rates were seen in the

two northern LHINs (13 and 14).

Above-average rates were also seen

in LHINs in southwestern and

southeastern Ontario (2 and 10).

EXHIBIT A.

Number, per 10,000 adults with diabetes, who received chronic dialysis or kidney transplantation in Ontario,

by Local Health Integration Network (LHIN), 2006/07–2010/

KEY FINDINGS

• Between 2006/07 and 2010/11, the

number of adults, per 10,000 with

diabetes, who underwent chronic

dialysis or kidney transplantation

varied by nearly 1.5-fold across

Ontario’s 14 LHINs. The provincial

average was 122 per 10,000 adults

with diabetes.

• The highest rates were seen in

central and northwestern Ontario

(LHINs 12 and 14). Above-average

rates were also seen in LHINs in

southwestern and northeastern

Ontario (4 and 13).

Number, per 100 adults with diabetes, who made a mental health visit for a psychotic or nonpsychotic illness in Ontario,

by Local Health Integration Network (LHIN), 2006/07–2008/

KEY FINDINGS

• Between 2006/07 and 2008/09, the

proportion of adults with diabetes

who visited a doctor for a psychotic or

On average over the three-year

period, about one in three adults with

diabetes made such a visit in Ontario.

• The highest rate of mental health

visits was seen in the Toronto Central

LHIN (7). Higher-than-average rates

were also seen in southwestern,

south-central and southeastern

Ontario (LHINs 1, 8 and 11).
