Evaluation of the effectiveness of the group interference-management model for hypertension

Objective To evaluate the six -month impact of centain community -based hypertension group interference- management in Shanghai.Methods The study was a randomized controlled trial. 369 patients with hypertension were randomized into 2 groups:intervention group(n=185) received the group interference- management and control group(n=184) received routine hyper tension management services. Before the study and 6 months after the beginning of experiment, questionnaire survey was conducted to investigate the changes in life style related behavior, in self-management behaviors, self-efficacy, health status, health service utilization and status of blood pressure control.Results The subjects in the intervention group showed greater improvement in compliance to change in life style related behavior, self-management behaviors(medication, interflow with doctor) self- efficacy to manage symptom, energy, health distress, health self- evaluation,and low spirit in comparison with the control group (all P 〈 0.05). They also had fewer visits of 0.74 frequency to outpatient service on average (P 〈0.05), fewer hospitalization of 0.07 frequency on average (P 〈 0.05). The value of systolic blood pressure and diastolic blood pressure in the intervention group decreased by 4.06 mmHg and 2.16 mmHg significantly more than those in the control group (all P 〈 0.05).Conclusion The community-based hypertension group interference-management model is more effective in improving change in life style related behavior, self- management behaviors, self- efficacy, health status, decrease of health service utilization and blood pressure control than the routine hypertension management services.
