Public and professional education on urgent therapy for acute ischemic stroke: a community-based intervention in Changsha.

Excessive delay of presentation for stroke in China is reported. In this study, an intervention trial was conducted to promote urgent therapy for acute ischemic stroke. Two communities in Changsha were selected as either intervention or control community from November 2007 to December 2011. Public and professional education was regularly implemented in the intervention community. Publics' knowledge about early identification and urgent therapy of ischemic stroke was surveyed before and after intervention in the two communities. During the intervention period, first-ever ischemic stroke cases occurring in the intervention community (intervention group) and that in the control community (control group) were collected and followed for 90 days. After intervention, the publics' knowledge levels in the intervention community improved significantly. Intervention group' average presentation time was shorter than control group (8.3 ± 5.8 vs. 10.5 ± 6.5 h, P = 0.018). Percentage of presentation time within 3 h (48.0 %), the rate of ambulance use (59.0 %), and thrombolytic therapy (9.3 %) in the intervention group was all obviously higher than that in the control group (21.5, 41.3, and 4.5, respectively). When admitted, the intervention group had lower mean systolic blood pressure (160.8 ± 26.7 vs. 164.7 ± 26.8 mmHg, P = 0.000) than control group. Survivors in the intervention group were more likely to be in higher Barthel index scoring groups than that in the control group at day 90 [(75, 50-100) vs. (65, 35-90), P = 0.035]. Public and professional education may promote prompt presentation and urgent therapy for ischemic stroke, which may be helpful for patients' prognosis.
