Perception versus actual performance in timely tissue plasminogen activation administration in the management of acute ischemic stroke.
The purpose of this study was to compare stroke teams’ perceptions of their performance against known metrics associated with tPA administration. It found that less than one-third (29.1 percent) of staff accurately identified their door-to-needle performance It concluded that hospitals often overestimate their ability to deliver timely tPA to treated patients.

Effectiveness and safety of dabigatran and warfarin in real-world US patients with non-valvular atrial fibrillation: a retrospective cohort study.
The researchers compared the effectiveness and safety of the new oral anticoagulant, dabigatran, with warfarin in clinical practice among a large nationally representative retrospective cohort of commercially insured patients in the United States. They found that compared with warfarin, dabigatran was associated with a lower risk of ischemic stroke or systemic embolism, hemorrhagic stroke, and acute myocardial infarction.

Validity of claims-based stroke algorithms in contemporary Medicare data: reasons for geographic and racial differences in stroke (REGARDS) study linked with medicare claims.
The researchers assessed the validity of diagnostic coding algorithms for identifying stroke in the Medicare population by linking data from the REasons for Geographic And Racial Differences in Stroke (REGARDS) Study to Medicare claims. They found that claims-based algorithms to identify stroke in a contemporary Medicare cohort had high positive predictive value and specificity, supporting their use as outcomes for etiologic and comparative effectiveness studies in similar populations.

Comprehensive versus consultative rehabilitation services postacute stroke: outcomes differ.
The researchers compared outcomes of veteran patients provided with comprehensive rehabilitation with those provided with consultative rehabilitation services after acute stroke using propensity scores. They found that comprehensive rehabilitation services are associated with greater recovery of physical and cognitive independence, improved home discharge likelihood, and improved 1 yr. survival.
