Case management reduces global vascular risk after stroke: secondary results from the The preventing recurrent vascular events and neurological worsening through intensive organized case-management randomized controlled trial.

ABSTRACT

BACKGROUND: Survivors of ischemic stroke/transient ischemic attack (TIA) are at high risk for other vascular events. We evaluated the impact of 2 types of case management (hard touch with pharmacist or soft touch with nurse) added to usual care on global vascular risk. METHODS: This is a prespecified secondary analysis of a 6-month trial conducted in outpatients with recent stroke/TIA who received usual care and were randomized to additional monthly visits with either nurse case managers (who counseled patients, monitored risk factors, and communicated results to primary care physicians) or pharmacist case managers (who were also able to independently prescribe according to treatment algorithms). The Framingham Risk Score [FRS]) and the Cardiovascular Disease Life Expectancy Model (CDLEM) were used to estimate 10-year risk of any vascular event at baseline, 6 months (trial conclusion), and 12 months (6 months after last trial visit). RESULTS: Mean age of the 275 evaluable patients was 67.6 years. Both study arms were well balanced at baseline and exhibited reductions in absolute global vascular risk estimates at 6 months median 4.8% (Interquartile range (IQR) 0.3%-11.3%) for the pharmacist arm versus 5.1% (IQR 1.9%-12.5%) for the nurse arm on the FRS (P = .44 between arms) and median 10.0% (0.1%-31.6%) versus 12.5% (2.1%-30.5%) on the CDLEM (P = .37). These reductions persisted at 12 months median 6.4% (1.2%-11.6%) versus 5.5% (2.0%-12.0%) for the FRS (P = .83) and median 8.4% (0.1%-28.3%) versus 13.1% (1.6%-31.6%) on the CDLEM (P = .20). CONCLUSIONS: Case management by nonphysician providers is associated with improved global vascular risk in patients with recent stroke/TIA. Reductions achieved during the active phase of the trial persisted after trial conclusion.
