Effect of self-help cognitive behavioral therapy for insomnia combined with trazodone hydrochloride on elderly patients with depression and insomnia / 中国医师杂志

ABSTRACT

Objective:To observe the efficacy of self-help cognitive behavioral therapy for insomnia (CBTI), trazodone hydrochloride and their combination in the treatment of depression and insomnia comorbidity in the elderly.Methods:90 elderly patients with insomnia and depression admitted to the 901th Hospital of the Joint Logistic Support Force from October 2019 to October 2021 were selected as the study subjects. They were divided into trazodone group, CBTI group and trazodone combined with CBTI group(combination group), with 30 cases in each group. Trazodone group was treated with oral trazodone hydrochloride, CBTI group was treated with self-help CBTI, and the combination group was treated with oral trazodone hydrochloride combined with self-help CBTI. All three groups were treated for 4 weeks. The sleep latency, total sleep time and sleep efficiency of each group were compared at the time of admission and after 4 weeks of treatment. Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) were used for sleep assessment before and after treatment, and Self-Rating Depression Scale (SDS) was used for depression assessment.Results:Before treatment, there was no significant difference among the three groups in terms of sleep latency, total sleep time, sleep efficiency, PSQI, ESS and SDS (all P>0.05). After treatment, the sleep latency of the three groups was shorter than that before treatment, and the total sleep time was longer than that before treatment (all P<0.05). The sleep efficiency of the trazodone group and the combination group was higher than that before treatment, with statistically significant difference (both P<0.05). The indexes of the combined group were better than those of the trazodone group and the CBTI group (all P<0.05). The sleep latency of the trazodone group was shorter than that of the CBTI group, and the total sleep time was longer than that of the CBTI group (all P<0.05), with statistically significant difference (all P<0.05). After treatment, the PSQI, except for the SDS of CBTI group, the ESS and SDS of the three groups were lower than those before treatment (all P<0.05). The PSQI, ESS and SDS of the combined group were lower than those of the trazodone group and the CBTI group, and the ESS and SDS of the trazodone group were lower than those of the CBTI group, with statistically significant difference (all P<0.05). Conclusions:For the elderly patients with depression and insomnia, the combination of self-help CBTI and trazodone can not only improve insomnia but also relieve depression symptoms, and the effect is better than that of trazodone and self -help CBTI alone.
