Educational interventions in kidney disease care: a systematic review of randomized trials.

BACKGROUND

There is increasing evidence that educational interventions aimed at empowering patients are successful in chronic disease management. Our aim was to conduct a systematic review of the effectiveness of such educational interventions in people with kidney disease. SYSTEMATIC REVIEW: A comprehensive search strategy was applied by using major electronic databases from 1980 to March 2007. Researchers independently reviewed titles and abstracts and extracted data from identified studies.

SETTING & POPULATION: Patients in any of the following stages of chronic kidney disease: early, predialysis, and dialysis. Kidney transplant recipients were excluded because this group has additional educational needs that are beyond the scope of this review.

SELECTION CRITERIA FOR STUDIES

Randomized controlled trials.

INTERVENTIONS

Structured educational interventions (involving informational and psychological components) with usual care.

OUTCOMES

Clinical, behavioral, psychological, and knowledge outcomes were considered.

RESULTS

22 studies were identified involving a wide range of multicomponent interventions with variable aims and outcomes depending on the area of kidney disease care. 18 studies provided significant results for at least 1 of the outcomes. The majority of studies aimed to improve diet and/or fluid concordance in dialysis patients and involved short- and medium-term follow-up. A single major long-term study was a 20-year follow-up of a predialysis educational intervention that showed increased survival rates. No study was found that addressed chronic kidney disease at an earlier stage.

LIMITATIONS

Meta-analysis was not possible because of study heterogeneity.

CONCLUSIONS

Multicomponent structured educational interventions were effective in predialysis and dialysis care, but the quality of many studies was suboptimal. Effective frameworks to develop, implement, and evaluate educational interventions are required, especially those that target patients with early stages of chronic kidney disease. This could lead to possible prevention or delay in progression of kidney disease.
