Abstract WMP11: Health-related Quality Of Life After Thrombolysis In Acute Stroke: Results From The Act Trial

Abstract

Background and aims: Recent evidence from thrombolysis trials indicate the non-inferiority of the Tenecteplase (TNK) to the Alteplase (TPA) with respect to functional outcomes in acute stroke patients. This study examines the predictors of patient-reported health-related quality of life (HRQOL) in acute stroke patients who received thrombolysis therapy. Methods: Data were used from all acute stroke patients included in AcT, a pragmatic, registry-linked randomized trial comparing TNK with TPA. HRQOL at 90-day post-randomization was assessed using the EuroQol-5D-5L (EQ-5D) visual analogue scale (VAS). Based on the Canadian norms, health state utilities were estimated from the EQ-5D items using the EQ-5D time trade-off approach. Tobit regression model and linear mixed-effects regression were used to evaluate the adjusted effect of type of treatment on health utility scores and VAS score, respectively. Results: Of the 1262 patients included in this analysis, 647(51.3%) were administered the TNK, 584(46.3%) were female, and 380(30.1%) were greater than or equal to 80 years old. There was no significant adjusted effect of the type of thrombolysis on health utility scores (adjusted beta coefficient [95%CI] = 0.029 [-0.001, 0.062]), but patients who received TNK reported higher adjusted VAS scores than those that received TPA [adjusted beta coefficient [95%CI] = 2.1 [-0.29, 4.49]). Older age (p < 0.01), female sex (p = 0.01), higher NIHSS score (p < 0.01) were associated with lower health utilities and VAS scores. Conclusion: There is no differential effect of the type of thrombolysis on patient-reported global HRQOL and health state utilities of acute stroke patients. Disparities in HRQOL were mainly explained by sex, age, and disease severity.
