【摘要】目的探讨行为干预对血液透析患者血磷达标率的影响,为临床血磷管理提供参考。方法选择乐山市人民医院透析中心患者146 例，按随机数表法分为对照组和实验组各73 例，对照组采用常规的健康教育方法，实验组采用行为干预模式进行健康教育，应用血磷代谢知识问卷及血磷控制自我效能量表、血磷控制遵医行为量表，对2 组患者干预前、干预后6 月的血磷代谢知识水平、血磷控制自我效能和遵医行为进行问卷调查，以及血磷值、血磷达标率相比较。结果干预后6 月实验组患者血磷代谢知识得分血磷控制自我效能和遵医行为得分明显高于对照组(t 值分别为-9.775，-4.170，-11.679；P 值分别为＜0.001，＜0.001，＜0.001)，血磷值低于对照组(t=3.641，P＜0.001)，血磷达标率明显高于对照组(χ2=7.650，P=0.006)。结论对血液透析患者采用行为干预健康教育模式，可以控制其血磷值，提高其血磷达标率。

【Abstract】Objective To explore the effect of behavioral intervention on the rate of blood phosphorus reaching the standard level in hemodialysis patients in order to provide an alternative management for blood phosphorus. Methods A total of 146 patients in the Hemodialysis Center of our hospital were randomly divided into control group (n=73) and experiment group (n=73). Routine health education was used in the control group, and behavioral intervention model of health education was carried out in the experiment group. Questionnaire about blood phosphorus metabolism knowledge, self-efficacy scale for blood phosphorus control, and compliance behavior scale for blood phosphorus control were used to investigate the levels of blood phosphorus metabolism knowledge, self- efficacy of blood phosphorus control and compliance behavior as well as the rate of blood phosphorus reaching the standard level before and after the intervention for 6 months in the two groups. Result After the intervention for 6 months, the scores of blood phosphorus metabolism knowledge (t=- 9.775), self- efficacy of blood phosphorus control (t=- 4.170) and compliance behavior (t=-11.679) were significantly higher in the experiment group than in the control group (P＜0.001); the average blood phosphorus value was lower in the experiment group than in the control group (t=3.641,P＜0.001); and
the rate of blood phosphorus reaching the standard level was significantly higher in the experiment group than in the control group (χ ２=7.65, P ＜0.006). Conclusion Behavioral intervention model of health education was useful to control blood phosphorus level and to increase the rate of blood phosphorus reaching the standard level in hemodialysis patients
