Chronic kidney disease (CKD) threatens patient safety, yet few interventions educate patients about kidney-specific safety hazards. We sought to develop and usability test an educational program designed to promote patient awareness of relevant safety topics in CKD.


We included 4 patient safety objectives in a tablet-based educational program: 1) avoidance of non-steroidal anti-inflammatory drugs (NSAIDs); 2) hypoglycemia awareness (only for individuals with diabetes); 3) temporary cessation of certain medications while acutely volume deplete (i.e. "sick day protocol"); and 4) contrast dye risk awareness. Content was developed for each objective using plain language principles. Teaching strategies optimized human-computer interaction and content retention; audio, animation, and clinical vignettes reinforced themes. For example, using a vignette of a CKD patient with pain and pictures of common NSAIDs, participants are asked, “which of the following pain medicines are safe for Mr. Smith to take for his belly pain?” Assessment methods consisted of pre- and post- knowledge surveys, with provision of correct responses and explanations. Usability testing was performed among patients with CKD, and program tasks completion were rated as 1) no error, 2) non-critical error (self-corrected), or 3) critical error (not completed).


All usability participants owned a mobile device and used it daily. Of 318 total tasks there were 3 non-critical errors (1%) and 6 critical errors (2%). One participant accounted for 7 of all total errors. All participants rated use of the tablet as ‘very easy,’ activity length as ‘just right’ (vs too long/short), the use of clinical vignettes as helpful, and would recommend this activity to others; the majority felt the program was ‘very’ or ‘somewhat easy’ to use (80%) and use of the audio was helpful (60%). All rated the activity between 8 (60%) and 10 (20%) on a scale of 1 to 10 (best). All usability testing recommendations were incorporated into the final version of the educational program.


A tablet-based patient safety educational program is acceptable and usable among individuals with CKD. Future studies will explore its impact on health outcomes in this high-risk population.
