BackgroundInsomnia is common in patients undergoing maintenance hemodialysis (MHD). Long-term use of sedative-hypnotic agents is often correlated with increasing adverse effects. Auricular acupressure therapy (AAT) applied to specific auricular acupoints for managing insomnia has achieved favorable outcomes in a hemodialysis unit. This pilot study was performed to demonstrate the potential of AAT for insomnia in MHD patients and to prepare for a future randomized controlled trial.MethodsEligible patients were enrolled into this descriptive pilot study and received AAT designed to manage insomnia for 4 weeks. Questionnaires that used the Pittsburgh sleep quality index (PSQI) were completed at baseline, after a 4-week intervention, and 1 month after completion of treatment. Sleep quality and other clinical characteristics, including sleeping pills taken, were statistically compared between different time points.ResultsA total of 22 patients were selected as eligible participants and completed the treatment and questionnaires. The mean global PSQI score was significantly decreased after AAT intervention (p<0.05). Participants reported improved sleep quality (p<0.01), shorter sleep latency (p<0.05), less sleep disturbance (p<0.01), and less daytime dysfunction (p=0.01). They also exhibited less dependency on sleep medications, indicated by the reduction in weekly estazolam consumption from 6.98±4.44 pills to 4.23±2.66 pills (p<0.01). However, these improvements were not preserved 1 month after treatment.ConclusionIn this single-center pilot study, complementary AAT for MHD patients with severe insomnia was feasible and well tolerated and showed encouraging results for sleep quality.
