Learning Objective 1: The participants will learn how to design a theory-based intervention.

Learning Objective 2: The participants will learn what is an evidence-based practice from the results of an intervention study.


The purpose of this study was to evaluate the effectiveness of a phosphorous control protocol based on the self-regulatory theory for hemodialysis patients with phosphatemia.


A quasi-experimental pre -post with control group design was used in this study.

The self-regulation protocol in this study is a 4-week intervention developed for hemodialysis patients with hyperphosphatemia. This protocol is primarily based on self-regulation theory. All participants were evaluated with phosphorous level at baseline and at one month after a 4-week intervention. .


Twenty-eight hemodialysis patients were selected from two dialysis centers of medical university hospital in southern Taiwan. Those in the experimental group (n=14) attended a 60-90 minutes self-regulation protocol once per week for four weeks.; participants in the control group (n=14) received only routine care.


There were significant differences in serum phosphrous level between the two groups. Experimental group had a significant decrease in mean phosphrous level from 7.41.4mg/dl to 6.41.4mg/dl (P<0.001). However, control group did not have significant difference in mean phosphrous level from 6.70.7mg/dl to 6.80.5mg/dl (P=0.912).

Conclusion }Suggestion

The finding of this study may provide an evidence to launch a clinical program for patients with hyperphosphatemia in hemodialysis center. Furthermore,

The theory-driven protocol developed in this study could serve as a reference for researcher who are interested in intervention study of behavioral modification
