Abstract
BACKGROUND

Hypertension is a critical public health problem globally. Antihypertensive drugs can create an extra burden on hypertension patients' self-regulation leading to an imbalance of blood supply and demand. This study aimed to evaluate the effect of auricular plaster therapy combined with western medicine to treat primary hypertension in older people.

AIM

To carry out a systematic review and meta-analysis for the effect of auricular plaster in elderly hypertension patients.

METHODS

Multiple databases like PubMed, EMBASE, Cochrane Library, Chinese Biomedical Literature on Disc, China National Knowledge Infrastructure, Wan Fang and Chinese Science and Technology Periodical Database were used to search for the relevant studies and full-text articles involved in the evaluation of auricular plaster combined with western medicine and western medicine alone for primary hypertension in older people. All included articles were quality assessed and the data analysis was conducted with the Review Manager (5.4). Forest plots, sensitivity analysis and funnel plots were also performed on the included articles.

RESULTS

In this analysis, fourteen (14) relevant studies were included. The Meta-analysis showed a significant difference in the effective ratio (OR = 3.62; 95%CI, 2.46 to 5.33; P < 0.00001), diastolic blood pressure change (5.68 mmHg; 95%CI, 3.49 to 7.87; P < 0.00001), systolic blood pressure change (MD = 8.78 mmHg; 95%CI, 5.04 to 12.53; P < 0.00001) and symptom score (MD = 3.20; 95%CI, 1.23 to 5.18; P = 0.001) between auricular plaster combined with western medicine group and western medicine alone group. One bias was detected as selection bias and another two in reporting bias. Sensitivity analysis fulfilled the stability of the results.

CONCLUSION

Our study suggested that auricular plaster combined with western medicine improved primary hypertension better than western medicine alone. Limited by the quality of included studies, further studies should be performed to confirm our findings.
