Information provision for stroke patients and their caregivers

The provision of information has been recommended as a key component of service provision after stroke. However, research suggests that patients' understanding of stroke and associated issues remains poor. We determined to undertake a systematic review of information provision strategies for patients and their carers after stroke.

To examine the effectiveness of an information and/or education strategy to improve the outcome of stroke patients and/or their identified caregivers.

Relevant trials were identified in the Cochrane Stroke Group Specialised Trials Register (last searched: June 2000). Additional intervention-based search strategies were developed for: The Cochrane Controlled Trials Register (CENTRAL/CCTR) Medline; Embase; CINAHL; ISI citation index; Science and Social Science Citation Indexes; ISI Web of Science Service; Aslib Index to UK theses; Dissertation Abstracts International, ASSIA and Psychlit/PsycINFO. We also searched the Journal of Advanced Nursing, bibliographies of retrieved papers, relevant articles and books.

Two or three investigators independently assessed trials and abstracts identified for eligibility, methodological quality and other participant characteristics.

Data were extracted independently using piloted data extraction forms. The primary outcomes were knowledge about stroke and stroke services, and impact on health, specifically mood.

We identified 152 abstracts, of which 36 studies were potentially relevant to this review. The current analysis includes nine completed trials, a further eight studies are ongoing. Of the nine trials, three evaluated a programme of lectures and the remaining trials evaluated the provision of information. There is some evidence that information combined with educational sessions improved knowledge and was more effective than providing information only. Information provision only had no effect on mood, perceived health status or quality of life for patients or carers. Two trials used an objective measure of satisfaction and no significant differences were found between groups. One trial reported that information and education sessions for carers improved 'family functioning'.

The results of the review are limited by the variable quality of the trials and the wide range of outcome measures used. The general effectiveness of information provision has not been conclusively demonstrated. Future work should address the expressed needs of patients and carers and seek to identify appropriate teaching strategies which can be successfully implemented within clinical practice.
