Information topics important to chronic kidney disease patients: a systematic review.

It is essential to identify the information topics that are important to chronic kidney disease (CKD) patients to provide 'appropriate' information that will improve their knowledge, promote independence and encourage them to self-manage their illness. This paper, through a systematic review, explores the existing body of evidence on the information needs of CKD patients to identify information topic areas important to these patients and highlight factors that influence a patient's information needs.
