The prevalence of stroke and associated disability.

BACKGROUND: There are limited data available on the prevalence of stroke in the United Kingdom. Such data are important for the assessment of the health needs of the population. This study aimed to determine the prevalence of stroke and the prevalence of associated dependence in a district of northern England. METHODS: This was a two-stage point prevalence study. A valid screening questionnaire was used to identify stroke survivors from an age- and sex-stratified sample of the population aged 45 years and over in a family health services authority district. This was followed by assessment of stroke patients with scales of disability and handicap. RESULTS: The overall prevalence of stroke was found to be 17.5/1000 (95 per cent confidence interval (CI) 17.0, 18.0). The prevalence of stroke-associated dependence was 11.7/1000 (95 per cent CI 11.3, 12.1). Self-reported comorbidity was most commonly due to circulatory and musculoskeletal disorders. CONCLUSIONS: The prevalence of stroke in this district is considerably higher than current guidelines and previous results suggest. Nevertheless, the result from this study combined with that from a previous study in another district in the United Kingdom should allow those interested in epidemiologically based health needs assessment to make reasonable estimates of the burden of stroke in their area.

Randomized controlled trial of a comprehensive stroke education program for patients and caregivers.

BACKGROUND AND PURPOSE: We report the findings of a randomized controlled trial to determine the effectiveness of a multidisciplinary Stroke Education Program (SEP) for patients and their informal carers. METHODS: Two hundred four patients admitted with acute stroke and their 176 informal carers were randomized to receive an invitation to the SEP or to receive conventional stroke unit care. The SEP consisted of one 1-hour small group educational session for inpatients followed by six 1-hour sessions after discharge. The primary outcome measure was patient- and carer-perceived health status (SF-36) at 6 months after stroke. Knowledge of stroke, satisfaction with services, emotional outcome, disability, and handicap and were secondary outcome measures. RESULTS: Only 51 of 108 (47%) surviving patients randomized to the SEP completed the program, as did 20 of 93 (22%) informal carers of surviving patients. Perceived health status (Short Form 36 [SF-36] health survey) scores were similar for SEP patients and controls. Informal carers in the control group scored better on the social functioning component of the SF-36 than the SEP group (P=0.04). Patients and informal carers in the SEP group scored higher on the stroke knowledge scale than controls (patients, P=0.02; carers, P=0. 01). Patients in the SEP group were more satisfied with the information that they had received about stroke (P=0.004). There were no differences in emotional or functional outcomes between groups. CONCLUSIONS: Although the SEP improved patient and informal carer knowledge about stroke and patient satisfaction with some components of stroke services, this was not associated with an improvement in their perceived health status. Indeed, the social functioning of informal carers randomized to the SEP was less than in the control group.

Is the SF-36 suitable for assessing health status of older stroke patients?

INTRODUCTION: The Medical Outcomes Study short form 36 health survey (SF-36) is being increasingly used and recommended as a suitable measure of subjective health status. However, it is unlikely that any measure will be appropriate for all groups. We wished to determine the suitability of the SF-36 for assessing quality of life in older stroke patients. METHODS: A screening questionnaire was used to identify prevalent cases of stroke from a random sample of 2000 subjects aged 45 years and over. The SF-36 was included as part of a self-completion questionnaire posted to each stroke patient. Data quality indicators were analysed. RESULTS: We identified 104 cases of stroke and the response rate for the SF-36 questionnaires sent was 83%. Completion rates for individual items ranged from 66 to 96%. All items in the role physical and role emotional scales had completion rates < 75%. The percentage of subjects for whom an individual scale score could be computed ranged from 67 to 96%, being lowest for the role physical and role emotional scales. Floor effects were high (> 15%) for these two scales and for the social functioning and physical functioning scales. Ceiling effects were substantial (> 15%) for the two role effect scales and for social functioning and bodily pain. CONCLUSIONS: This study has shown high response rates from older stroke patients to a postal questionnaire incorporating the SF-36. The poor completion rates and consequent inability to compute scores for a large proportion of responders in certain scales raises concerns about the perceived relevance of these sections. Results for the response effects suggest that, on its own, the instrument is not suitable for assessing outcome. When data quality indicators were examined, it appears that postal administration of the SF-36 is not appropriate for assessing quality of life of older stroke patients.

Satisfaction with information and advice received by stroke patients.

OBJECTIVE: To determine levels of satisfaction with information and advice received about stroke disease and relevant issues by community-dwelling stroke survivors. DESIGN: An interview questionnaire survey. SETTING: A family health services authority area in northern England. SUBJECTS: Stroke survivors identified by a valid screening questionnaire from a stratified random sample of 2000 subjects aged 45 years and over. MAIN OUTCOME MEASURE: Proportion of subjects interviewed responding positively to the question 'Do you think you have received enough advice and information on ...?' eighteen topics considered relevant to stroke survivors. RESULTS: The screening process identified 116 stroke survivors, of whom 76 agreed to be interviewed. The majority (> 80%) of patients were satisfied with information and advice received on lifestyle and health promotion issues, incontinence and their current treatment. However, satisfaction was poor for the areas of stroke disease in general, its effects, available services, and legal and financial affairs (range, 28-75% satisfied). CONCLUSIONS: Deficits in the provision of adequate information and advice to stroke patients on relevant issues have beer identified in this study of a representative sample of community-dwelling stroke survivors. These deficits need to be addressed by those providing care for stroke patients in order to improve patients satisfaction.
