The interaction between self-care behavior and disease knowledge on the decline in renal function in chronic kidney disease

Multidisciplinary care can improve the outcomes of chronic kidney disease (CKD), however the contribution of self-care behavior and knowledge about CKD is unclear. This study enrolled 454 participants with CKD stages 1-5 not on dialysis. Structured questionnaires were used to evaluate self-care behavior and kidney disease knowledge. Rapid decline in renal function was defined as the decline in estimated filtration rate>3 ml/min per 1.73 m(2)/year within 1-year prior to enrollment. The mean age of all study participants was 65.8 +/- 12.1 years and 55.9% were male. The elderly had better self-care behavior while younger participants had better disease knowledge. Both high self-care and high disease knowledge scores were significantly associated with and had a synergistic effect on decreasing the risk of rapid decline in renal function. CKD patients with better self-care behavior and better kidney disease knowledge had lower risk of rapid decline in renal function.

Automated summary

The study found that CKD patients who engage in self-care and have a good understanding of the disease have a lower risk of rapid decline in renal function.
