Communicating health risk in chronic kidney disease: a scoping review

Communicating risk is a key component of shared decision-making and is vital for the management of advanced chronic kidney disease (CKD). Despite this, there is little evidence to suggest how best to communicate health risk information to people living with CKD. The aim of this review was to identify and understand the nature of evidence-based risk communication strategies for people living with CKD.

We searched MEDLINE, CINAHL and Scopus databases for articles which described or evaluated the use of risk communication strategies within the renal population. Similar risk communication strategies were collated and summarised narratively.

A total of 3700 sources were retrieved from the search, of which 19 were included in the review. Eleven studies reported primary research, and eight reported either narrative or systematic reviews. Seven main risk communication strategies were identified: framing, absolute versus relative risk, natural frequencies versus percentages, personalised risk estimates, qualitative risk communication, best-case/worst-case framework and use of graphs and graphics. There was a paucity of risk communication strategies specific to the CKD population.

Evidence-based strategies to improve health risk communication for patients living with CKD are lacking. There is a need to establish the informational and communication preferences for patients living with CKD to better understand how to best communicate health risk information to individuals in this population.
