STUDY OBJECTIVE
The aim of this study was to determine the prevalence of stroke survivors in a health district population aged 55 years and over.
DESIGN
This was a point prevalence study using two-stage postal questionnaires sent to an age stratified random sample of the population.
SETTING
A district health authority in northern England with a resident population of 723,000.
SUBJECTS
Altogether 18,827 residents aged 55 years or over.
MAIN RESULTS
Prevalence was found to increase with age and, apart from the very elderly, males had a higher prevalence than females. Overall prevalence was found to be 46.8/1,000 (95% CI 42.5, 51.6). 23% of respondents reported full recovery from stroke. Cognitive impairments (33%), problems with lower limbs (33% for right leg; 27% for left leg) and speech difficulties (27%) were the most common residual impairments.
CONCLUSIONS
Current guidelines to purchasers on the provision of services to those who have had a stroke may under-estimate prevalence rates by as much as 50%. This could lead to a shortfall in provision of services designed to support people in the months and years following their stroke.
研究目的
本研究旨在确定55岁及以上健康区人群中中风幸存者的患病率。
设计
这是一项现况患病率研究，采用两阶段邮寄问卷的方式，发送给按年龄分层的随机抽样人群。
研究地点
英格兰北部的一个地区卫生当局，常住人口为723,000。
研究对象
共有18,827名55岁及以上的居民。
主要结果
发现患病率随年龄增长而增加，除了高龄老人外，男性患病率高于女性。总体患病率为46.8/1000（95%可信区间42.5, 51.6）。23%的受访者报告中风后完全康复。认知障碍（33%）、下肢问题（右腿33%；左腿27%）和言语困难（27%）是最常见的残留障碍。
结论
目前向中风患者提供服务的购买者指南可能会将患病率低估多达50%。这可能导致在中风后的数月和数年中，为支持患者而设计的服务供应不足。
