Effect of Nurse CaseManagement ComparedWith Usual Care on Controlling Cardiovascular Risk Factors in PatientsWith Diabetes A randomized controlled trial

RESEARCH DESIGN AND METHODS—A randomized controlled trial of diabetic patients that had blood pressure (BP) .140/90 mmHg, hemoglobin A1c (HbA1c) .9.0%, or LDL .100 mg/dL. Intervention patients received case management (n = 278) versus usual care (n = 278) over a 1-year period. The primary outcome was the percentage of patients achieving simultaneous control of all three parameters (defined by BP,130/80mmHg,HbA1c,8.0%, and LDL,100 mg/dL) at 1 year. Secondary outcomes included improvements within each individual component of the composite primary outcome. Differences between groups were analyzed using t tests, Pearson x tests, and linear and logistic regression.
