Aims: To examine the effectiveness of a self-management intervention compared with usual care in adults with chronic kidney disease (CKD) on self-management, knowledge, self-efficacy, health-related quality of life, and blood pressure.
Design: A parallel group randomized controlled trial.
Methods: Patients aged ≥ 18 years with CKD stages 3-5 were recruited between November 2015 and June 2016. Participants were randomly allocated into either the intervention (N = 68) or control group (N = 67). The control group received usual care, while the intervention group received usual care plus a self-management programme from a nurse. The intervention was guided by social cognitive theory (SCT) and included a face-to-face educational session followed by telephone support. Both groups were followed for 16 weeks.
Results: There were no significant differences in self-management, knowledge, self-efficacy, health-related quality of life, and blood pressure between the two groups at baseline. At week 16, compared with the control group, large effect sizes for improved self-management, knowledge, and self-efficacy were detected. For health-related quality of life, the physical and mental health components significantly improved. However, no significant differences in either systolic or diastolic blood pressures were found.
Conclusion: In earlier stages of CKD, a simple self-management education benefits patients.
Impact: Effective self-management in the earlier stages of CKD contributes to slowing its progression, improving health outcomes and lowering the burden on healthcare systems. This study demonstrated that SCT increases CKD self-management by strengthening knowledge and self-efficacy. Nurses can give this education.
