The dissemination of research evidence from which clinical practice should be based poses many well-documented problems for nurses. This study set out to overcome some of the common barriers to dissemination by providing a research-based clinical handbook for continence care. The impact of the handbook on nurses’ knowledge of both urinary and faecal incontinence was tested using an experimental and control group. The experimental group received the handbook while the control group did not. Both groups completed an assessment questionnaire at week 1, prior to the intervention in the experimental group, followed by a second assessment at week 7 after the intervention in the experimental group. Data were collected using semistructured questionnaires. Statistically significant improvements in knowledge were found for those nurses who received a copy of the handbook, and nurses reported that they found the handbook useful and acceptable as a form of clinical updating. The dissemination of research findings is essential if evidence-based nursing is to become a reality, and this study clearly demonstrates one method by which this can be successfully achieved.
