Abstract： Objective To explore the effect of doctor-patient interaction based on information platform on hypertensive patients' self-efficacy and treatment compliance in community. Methods A convenience sampling method was used, and 280 patients with hypertension in Huaxin community health service centre were included. Patients were divided into interactive group (89 cases) and control group (191 cases) according to their wishes. Control group received a regular follow-up at community clinics, while interactive group participated in the doctor-patient interaction based on information platform at the same time of regular community clinic visit for 3 months. All patients were investigated using Self-efficacy Assessment Scale for Hypertensives and Treatment Compliance Questionnaire before and after intervention, which was used for effectiveness analysis. Results Before intervention, two groups showed no significant difference in self-efficacy (t=1.635,P>0.05), but there was significant difference in treatment compliance [interactive group:8.00(5.00) vs. control group:10.00(3.00)] (Z=4.409,P<0.05). After the intervention, two groups showed no significant difference in treatment compliance (Z=0.784,P>0.05), but there was significant difference in self-efficacy (interactive group:34.42 ± 4.49 vs. control group:32.63 ± 5.53) (t=2.867, P<0.01), which in interactive group was higher. Before and after the intervention, self-efficacy and the treatment compliance had significantly increased in interactive group (P<0.05). while not significantlyincreased in control group (P>0.05). Before intervention, there was a significant positive correlation between the total score of self-efficacy and treatment compliance(r=0.500, P<0.001), drug therapy compliance (r=0.327, P<0.001) and Non-drug treatment compliance (r=0.469, P<0.001) in two groups, while there was lower positive correlation after intervention. Conclusion The doctor-patient interaction project of community hypertension supervision based on informatization platform is effective on the improvement of self-efficacy and the treatment compliance through the enhanced doctor-patient communication, particularly in promoting the role of self-efficacy to accelerate the improvement of health behaviors, compliance behavior and treatment compliance.
