Sustained benefit of a community and professional intervention to increase acute stroke therapy.

BACKGROUND: The ultimate test of an educational intervention is the sustainability of the effect after the intervention ceases. METHODS: The TLL Temple Foundation Stroke Project was a quasi-experimental study aimed at increasing Food and Drug Administration-approved acute stroke therapy in a nonurban community in east Texas. During the intensive community and professional intervention (phase 2), significantly more patients with acute stroke received intravenous tissue plasminogen activator (tPA) compared with the preintervention period (phase 1). In the comparison community, no change was noted. We present the results of tPA treatment in the 6 months after the intervention ended (phase 3). RESULTS: Two hundred thirty-eight patients had a validated stroke during phase 3. Among patients who experienced an ischemic stroke, 11.2% in the intervention group received intravenous tPA compared with 2.2% in phase 1 (P =.007). In the comparison group, 1.4% received intravenous tPA in phase 3 compared with 0.7% in phase 1 (P>.99). Among eligible candidates for treatment, 69.2% were treated in phase 3 in the intervention community compared with 13.6% in phase 1 (P =.002). In the comparison group, 20.0% were treated in phase 3 compared with 6.7% in phase 1 (P =.45). There was 1 protocol violation among the 9 patients treated in the intervention community in phase 3. CONCLUSIONS: There was a sustained benefit of the intervention in increasing tPA treatments in the intervention community even after cessation of the educational effort. Treatments in the control community remained few through all 3 phases of the study. A carefully planned multilevel intervention can improve community stroke treatments even in a nonurban community.

Improving delivery of acute stroke therapy: The TLL Temple Foundation Stroke Project.

BACKGROUND AND PURPOSE: Only a small minority of acute stroke patients receive approved acute stroke therapy. We performed a community and professional behavioral intervention project to increase the proportion of stroke patients treated with approved acute stroke therapy. METHODS: This study used a quasi-experimental design. Intervention and comparison communities were compared at baseline and during educational intervention. The communities were based in 5 nonurban East Texas counties. The multilevel intervention worked with hospitals and community physicians while changing the stroke identification skills, outcome expectations, and social norms of community residents. The primary goal was to increase the proportion of patients treated with intravenous recombinant tissue plasminogen activator (rTPA) from 1% to 6% of all cerebrovascular events in the intervention community. RESULTS: We prospectively evaluated 1733 patients and validated 1189 cerebrovascular events. Intravenous rTPA treatment increased from 1.38% to 5.75% among all cerebrovascular event patients in the intervention community (P=0.01) compared with a change from 0.49% to 0.55% in the comparison community (P=1.00). Among the ischemic stroke patients, an increase from 2.21% to 8.65% was noted in the intervention community (P=0.02). The comparison group did not appreciably change (0.71% to 0.86%, P=1.00). Of eligible intravenous rTPA candidates, treatment increased in the intervention community from 14% to 52% (P=0.003) and was unchanged in the comparison community (7% to 6%, P=1.00). CONCLUSIONS: An aggressive, multilevel stroke educational intervention program can increase delivery of acute stroke therapy. This may have important public health implications for reducing disability on a national level.
