Many aspects of CKD management rely heavily on patient self-care, including medication and dietary adherence, self-monitoring of BP, and daily physical activity. Growing evidence suggests that incorporating smartphone-based applications can support self-care in CKD and chronic disease more generally. A recent study, published in CJASN, found that only a small subset of CKD applications was highly rated by both patients and nephrologists. Patients’ impressions of application quality were not directly linked to consumer application ratings or nephrologist impressions. Julie Wright-Nunes is senior author of the study.
