Abstract WP421: A Peer-led Intervention Improves Stroke Survivors’ Blood Pressure Control
Background: Hypertension is a major risk factor for stroke recurrence but it is poorly controlled among stroke survivors, particularly from minority groups. The Prevent Recurrence of All Inner-city Strokes through Education (PRAISE) trial tests whether a community-based, peer-led stroke education intervention improves stroke risk factors, primarily blood pressure control.
Methods: Using community-based participatory research, clinicians, educators and stroke survivors developed a six-session peer-led workshop to help stroke survivors understand their illness, and identify and manage their recurrent risks, particularly hypertension. We recruited 600 individuals with a history of stroke or TIA within the past 5 years who were randomized to the intervention or a wait-list control group. At baseline, 6 and 12 months, we measured participants’ blood pressures, socio-demographics, beliefs and behaviors. Six-month data collection has been completed.
Results: Participants have a mean of 63 years, the majority are female (60%), Black or Latino (81%) and live in poverty (56%). At baseline, 31% in both groups had uncontrolled blood pressure (<140/90 mmHg). At six months, the intervention group demonstrated better blood pressure control when compared to the control group, 76% vs. 65% (p=0.01). The intervention group also had a significant blood pressure reduction of 3.6/2.0mmHg (p=0.005/p=0.04) compared to the control group (+0.5/-0.5mmHg).
Conclusions: A peer-led educational program developed through a community-academic partnership was successful in improving blood pressure control at 6 months. While 12-month data will confirm the longevity of this impact, PRAISE is simple, culturally appropriate and inexpensive, and may represent an important and sustainable secondary stroke prevention strategy.
