PREVALENCE OF SELF-REPORTED STROKE IN A POPULATION IN NORTHERN ENGLAND

Study objective - The aim of this study was to determine the prevalenc e of stroke survivors in a health district population aged 55 years an d over. Design - This was a point prevalence study using two-stage pos tal questionnaires sent to an age stratified random sample of the popu lation. Setting - A district health authority in northern England with a resident population of 723 000. Subjects - Altogether 18 827 reside nts aged 55 years or over. Main results - Prevalence was found to incr ease with age and, apart from the very elderly, males had a higher pre valence than females. Overall prevalence was found to be 46.8/1000 (95 % CI 42.5, 51.6). 23% of respondents reported full recovery from strok e. Cognitive impairments (33%), problems with lower limbs (33% for rig ht leg; 27% for left leg) and speech difficulties (27%) were the most common residual impairments. Conclusions - Current guidelines to purch asers 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.
