Abstract

PURPOSE
The purpose of this study was to examine their levels of knowledge of the kidney, self-efficacy, and kidney function in pre-dialysis patients with chronic renal insufficiency.
METHODS
A total of 142 pre-dialysis patients with chronic renal insufficiency were recruited from a nephrology clinic of a hospital in Korea. Participants' knowledge of the kidney, self-efficacy, and kidney function were measured, and the correlations between these factors were computed.
RESULTS
The levels of knowledge of the kidney were moderate, with a mean score of 12.30+/-5.35. Knowledge level was significantly correlated with age, education level, occupation, income, physical symptoms, and information resources (p<.05). The mean score for self-efficacy was 6.06+/-2.00. Self-efficacy was significantly associated with patients` age, education level, occupation, income, cigarette use, and information resources (p<.05). The mean score for kidney function was 35.66+/-18.68 mL/min/1.73 m2. Kidney function was significantly correlated with use of medications and drinking behavior (p<.05). Knowledge of the kidney was significantly correlated with self-efficacy (r=.31, p<.001), but not with kidney function. There was a significant correlation between self-efficacy and kidney function (r=.30, p<.001). Multiple regression analysis revealed that self-efficacy and drinking behavior accounted for 11% of the variance in kidney function of pre-dialysis patients with chronic renal insufficiency.
CONCLUSION
Nursing interventions are necessary to increase self-efficacy among pre-dialysis patients with chronic renal insufficiency in order to maintain their kidney function.
