OBJECTIVE: We aimed to evaluate the changes in cardiovascular-related health care utilization (drug therapies, hospitalizations) and mortality for the diabetic population during a 9-year period in Saskatchewan, Canada. RESEARCH DESIGN AND METHODS: We identified annual diabetes prevalence rates for people aged >or=30 years between 1993 and 2001 from the administrative databases of Saskatchewan Health. Annual rates of evidence-based drug therapies (antihypertensives, ACE inhibitors, beta-blockers, calcium channel blockers, 3-hydroxy-3-metaglutaryl coenzyme A reductase inhibitors [statins]), hospitalizations for cerebrovascular and cardiac events, and all-cause mortality were estimated. Rates were direct age and sex standardized using the 2001 Canadian population, and trends over time were assessed using Joinpoint regression. RESULTS: From 1993 to 2001, diabetes prevalence increased 34% (4.7-6.5%, P < 0.001) with the highest rates in men and those aged >or=65 years. The rate of increase in diabetes prevalence appeared to slow in those aged <65 years (P < 0.01 for trend). Significant increased use of evidence-based drug therapies was observed (41% increase in antihypertensive agents, 97% increase in ACE inhibitors, 223% increase in statin therapies; all P < 0.05 for trend). During this period, both cerebrovascular and cardiac-related hospitalizations declined by 36% (9.5 vs. 6.1 per 1,000) and 19% (38.0 vs. 30.6 per 1,000) (P < 0.05 for trends), respectively, with similar reductions regardless of sex. No change in all-cause mortality was observed (17.7 vs. 17.8 deaths per 1,000; P > 0.05). CONCLUSIONS: During our period of study, there was an increase in the utilization of evidenced-based drug therapies in people with diabetes and reductions in cardiovascular-related hospitalizations. Despite this, we observed no change in all-cause mortality.
