Objective:
The efficacy of auricular acupressure in patients with hypertension and insomnia is controversial. This systematic review aims to explore the effectiveness of auricular acupressure in reducing blood pressure and improving sleep in this population.
Methods:
We conducted an extensive database search in Cochrane Central Register of Controlled Trials, PubMed, Ovid LWW, Web of Science, Chinese Biomedical Literature Database, China Knowledge Resource Integrated Database, Wanfang Data, and China Science and Technology Journal Database on randomized controlled trials published from inception to November 2019 that compared auricular acupressure with a control or comparison group on blood pressure control and sleep improvement. Two reviewers independently conducted data screening and extraction. Study quality was evaluated using the Cochrane Handbook for Systematic Reviews of Interventions. Meta-analyses were performed on blood pressure, Pittsburgh Sleep Quality Index (PSQI), the efficacy rate of diagnostic and therapeutic criteria for traditional Chinese medicine syndromes (DTCTCMS), and the efficacy rate of guidelines for traditional Chinese medicine (new drug) clinical research (GTCMCR) by Revman 5.3.0.
Results:
A total of 18 randomized controlled trials with 1685 patients were identified. Compared with a control or comparison group, pooled meta-analyses showed that auricular acupressure significantly improved systolic blood pressure (MD = -15.05, 95% CI (-18.49, -11.61), P < 0.00001), diastolic blood pressure (MD = -8.41, 95% CI (-11.33, -5.48), P < 0.00001), PSQI (MD = -2.37, 95% CI (-4.64, -0.10), P=0.04), the efficacy rate of DTCTCMS (RR = 1.63, 95% CI (1.16, 2.28), P=0.004), and the efficacy rate of GTCMCR (RR = 1.25, 95% CI (1.12, 1.38)).
Conclusions:
The results demonstrated a favorable effect of auricular acupressure to reduce blood pressure and improve sleep in patients with hypertension and insomnia. Further studies to better understand the acupoints and intervention times of auricular acupressure are warranted.
