The effect of a self-management program on renal function control in patients with hemodialysis in Taiwan: A...

This study was designed to investigate the longitudinal effect of participating in a self-management program (SMP) on renal function control in patients receiving hemodialysis.

This randomized controlled trial enrolled a total of 58 patients at the hemodialysis center of a teaching hospital in Taiwan. The control group (n = 30) received the usual care and the experimental group (n = 28) received a 4-week SMP intervention. The results of the follow-up on the longitudinal data at 3, 6, and 9 months showed that the renal function indices, potassium and phosphorus levels, and interdialytic weight gain were significantly better than at the pre-test for the experimental group.

In terms of the interaction between group and time, the potassium level dropped significantly below the pre-test value only after 3 months (B = -0.31, SE = 0.15, p = .044), suggesting that the post-test potassium level had significantly decreased after 3 months. In terms of the interaction between group and time, the phosphorus level dropped significantly below the pre-test value only after 6 months (B = -0.53, SE = 0.28, p = .050), suggesting that the post-test phosphorus level significantly decreased after 6 months. Finally, the intervention could effectively control the weight change between dialysis sessions for up to 9 months (B = -1.34, SE = 0.30, p < .001).

The SMP intervention decreased potassium and phosphorus levels and helped control interdialytic weight gain in patients undergoing hemodialysis.
