Although previous studies using mass media have demonstrated successful public stroke awareness campaigns, they may have been too costly for smaller communities to implement. The goal of this study was to investigate if a novel emergency medical services (EMS) -sponsored community awareness campaign could increase public stroke awareness.
This was a pre- and postintervention study with 2 phases conducted between August 2005 and July 2007. During Phase I, strategic placement of stroke education media by EMS personnel was implemented in one county over a 2-year period. Five random-digit, standardized phone surveys measuring stroke awareness were conducted with county residents to assess the campaign's impact. In Phase II, EMS interventions and random-digit measurements were conducted in 4 additional counties with 4 counties randomly selected as controls.
A pattern of increasing stroke knowledge after exposure to the EMS intervention followed by declines in the absence of the intervention was observed during Phase I. EMS interventions also demonstrated a positive effect on the stroke knowledge of residents who lived in counties exposed to the intervention during Phase II with a statistically significant (P<0.05) increase observed in the proportion of respondents that named 2 stroke risk factors and 3 symptoms in comparison to either no changes or declines in the control counties. No evidence of a positive impact on knowledge of calling 911 for stroke was observed.
Results of this study suggest that the public's knowledge of stroke signs and symptoms was increased using communitywide EMS-based programs. Additional studies are needed to determine optimal methods for educating the public regarding the need to call 911 for stroke and to confirm these results in other locales.
尽管先前利用大众媒体开展的研究已证明中风公众意识宣传活动取得了成功,但对于较小的社区而言,实施这些活动的成本可能过高。本研究的目的是调查一项由新型紧急医疗服务(EMS)赞助的社区意识宣传活动能否提高公众对中风的认识。
这是一项于2005年8月至2007年7月期间分两个阶段进行的干预前后研究。在第一阶段,EMS人员在一个县内经过两年时间对中风教育媒体进行了战略布局。对该县居民进行了五次随机数字标准化电话调查以衡量中风认知情况,从而评估该宣传活动的影响。在第二阶段,在另外4个县开展了EMS干预及随机数字测量,随机选择4个县作为对照。
在第一阶段,观察到接触EMS干预后中风知识呈现增加的模式,而在没有干预的情况下则出现下降。在第二阶段,EMS干预对接触干预的县的居民的中风知识也显示出积极影响,与对照县没有变化或下降相比,在说出2个中风危险因素和3个症状的受访者比例方面观察到有统计学意义(P<0.05)的增加。未观察到对中风拨打911知识有积极影响的证据。
本研究结果表明,利用基于社区EMS的项目可提高公众对中风体征和症状的认识。需要进一步开展研究以确定就中风拨打911的必要性对公众进行教育的最佳方法,并在其他地区证实这些结果。
