Objective: To explore the effect of health education based on behavioral phased transformation theory in remote peritoneal dialysis patients in remote mountainous areas. Methods: Totally 84 cases of peritoneal dialysis catheterization in our hospital from April 2016 to May in -2018 were selected as the research subjects. After discharge, home peritoneal dialysis was performed. According to the random number table method, 42 cases in each group were divided into observation group and control group. The control group was given routine treatment and traditional health education. On the basis of conventional treatment, the observation group established a behavior based phased transformation of health education as a means of intervention. The two groups were all intervened for 6 months. Volume status and self-care behavior were evaluated and compared between the two groups within one week of admission and six months after intervention. Results: Before intervention, there was no significant difference in the capacity load between the observation group and the control group (P>0.05). The systolic and diastolic blood pressures of the observation group after intervention were (131.21±11.73) mmHg (1 mmHg=0.133kPa) and (80.24 ±10.62) mmHg respectively, which were significantly lower than those of the control group (140.31 ± 12.87) mmHg and (85.75 ± 11.73) mmHg, with significant differences (t=3.455, 2.302, P < 0.05); and the ultrafiltration volume of the observation group after intervention was (385.15 ± 105.1.8) ml was significantly higher than that of the control group (320.02±126.87) ml, with significant difference (t=2.561, P < 0.05); there was no significant difference in body mass and urine volume between the two groups after intervention (P > 0.05).The total score of the self-care ability scale in the observation group was (122.11 ± 8.52) points, which was significantly higher than that in the control group (94.24 ± 10.71) points. The difference was statistically significant (t=313.198, P<0.01) . Conclusion Health education based on the theory of behavioral phased transformation can help patients with peritoneal dialysis in remote mountainous areas to improve their capacity and improve their self-protection behavior, which has educational guiding significance.
