Effect of a managed care disease management program on diabetes care

To determine if processes and outcomes of diabetes care improved between 2000 and 2006 in a managed care health plan with a comprehensive diabetes disease management program. Cross-sectional. A total of 1650 randomly selected members with diabetes mellitus completed surveys in 2000, and 1256 randomly selected members with diabetes completed surveys in 2006. Survey and medical record data were analyzed using multivariable regression and predictive probabilities adjusted for age, education, and comorbidities. In 2006, patients were more likely to have proteinuria assessed (85% vs 74% in 2000), foot examinations performed (90% vs 86%), glycosylated hemoglobin levels measured (94% vs 87%), lipids measured (81% vs 70%), aspirin use recommended (67% vs 56%), and influenza immunizations administered (70% vs 63%). Glycosylated hemoglobin levels decreased by 0.60% (P
