EVALUATION OF OUTCOMES OF THE COMMUNITY-BASED INTERVENTION IN STROKE RISK REDUCTION IN THUA THIEN HUE PROVINCE

Background: Stroke, which has high mortality and disability rate, has been causing serious social and economic consequences. The results of study in 2018 in Thua Thien Hue province showed that stroke risk in next 10 years and the level of current stroke risk were quite high, and there were associate factors which can modify to prevent, reduce prevalence of high-risk prediction in next 10 years based on the community. Objectives: To evaluate the intervention outcomes in reducing high-risk predictable rate of stroke in next 10 years based on community in Thua Thien Hue province. Methodology: Controlled community intervention was conducted in two communes/wards including Tay Loc ward in Hue city and Quang Vinh commune in Quang Dien district, which represented the ecological regions with high-risk predictable level in next 10 years at high level, and two controlled communes/wards were Thuan Hoa ward and Quang Phu commune, respectively. The assessment was conducted after one year applying intervention methods among 800 participants aged 25-84 years in 4 control and intervention communes/wards. Results: In the intervention group, the current high risk of stroke level decreased from 12.0% to 4.7%. The forecast prevalence of high and very high stroke risk in the next ten years decreased from 10.2% to 6.2%, and the forecast rate of average 10-year risk decreased from 5.24 ± 6.76 (0-41.5) to 4.36 ± 5.02 (0-26.6). The figures in the control group did not change. The effective index indicated that the intervention was highly effective. Conclusion: The intervention reduced the prevalence of high and very high stroke risk levels in next ten years as well as the current high-risk level.
