Functional Outcome Measures of Recombinant Tissue Plasminogen Activator-Treated Stroke Patients in the Telestroke Technology.

The efficiency of telestroke programs in improving the rates of recombinant tissue plasminogen activator (rtPA) in stroke patients has been reported. Previous studies have reported favorable treatment outcomes with the use of telestroke programs to improve the use of rtPA, but functional outcomes are not fully understood. This study investigated the effect of telestroke technology in the administration of rtPA and related functional outcomes associated with baseline clinical variables. Retrospective data of a telestroke registry were analyzed. Univariate analysis was used to compare demographic and clinical variables in the rtPA group and the no rtPA group and between the improved functional ambulation group and the no improvement group. A stepwise binary logistic regression identified factors associated with improved functional outcome in the total telestroke population and in the subset of the telestroke population who received rtPA. In adjusted analysis and elimination of any multicollinearity for patients who received rtPA in the telestroke setting, obesity (odds ratio [OR] = 2.138, 95% confidence interval [CI], 1.164-3.928, P < .05), higher systolic blood pressure at the time of presentation (OR = 1.015, 95% CI, 1.003-1.027, P < .05), and baseline high-density lipoprotein at the time of admission (OR = 1.032, 95% CI, 1.005-1.059, P < .05) were associated with improved functional outcomes. Increasing age (OR = 0.940, 95% CI, 0.916-0.965, P < .0001) and higher calculated National Institutes of Health Stroke Scale (OR = 0.903, 95% CI, 0.869-0.937) were associated with a poorer outcome in rtPA-treated patients. Telestroke technology improves functional outcomes at spoke stations where neurological expertise is unavailable. Further studies are necessary to determine how telestroke technology can be optimized, especially to improve contraindications and increase eligibility for thrombolysis therapy.
