Abstract:OBJECTIVE To systematically evaluate the effects of motivational interviewing for hypertension. METHODS A randomized controlled trial (RCT) was conducted to retrieve multiple Chinese and English databases from the self-built library to a motivational interviewing for hypertension patients published in December 2018. Cochrane biased risk assessment tools were used for literature evaluation, data analysis was performed using RevMan5.3 Software, and descriptive analysis was not possible for conversion of the combined data. RESULTS A total of 17 RCTs and 2 445 patients were included. Meta-analysis showed that compared with the control group, motivational interviewing improved patients’ quality of life and self-efficacy, and the differences were statistically significant(P<0.05); in the aspect of antihypertensive, subgroup analysis of different intervention time, the results showed that the systolic blood pressure of the experimental group was significantly lower than the control group (P<0.05), and only the intervention time was <12 or 48 weeks interventions. At month, the difference in diastolic blood pressure between the two groups was statistically significant (P<0.05). Descriptive analysis showed that motivational interviewing could improve patient self-management. CONCLUSION Motivational interviewing could improve patients’ quality of life, improve patients’ self-management ability and self-efficacy, and reduce systolic blood pressure. However, there was no obvious effect on the diastolic blood pressure of 12 or 48 weeks, but it still needed to be clinically multi-centered and large. The RCT of the sample was developed to verify its effectiveness.
