Abstract: PURPOSE: To evaluate the effect of non-pharmacological interventions in preventing postoperative delirium in patients with oral cancer, summarize the main components of non-pharmacological interventions in patients with oral cancer, and aid clinical decision-making. METHODS: The literatures on the prevention of postoperative delirium by non-pharmacological interventions in patients with oral cancer were searched in 8 Chinese and English electronic databases(Embase, PubMed, Web of Science, The Cochrane Library, CNKI, Wanfang database, VIP, China Biomedical Literature Service System). The search was conducted from inception to October 2023. The primary outcomes were the incidence and duration of postoperative delirium. Cochrane risk of bias assessment tool was used to evaluate the randomized controlled trials. Review manager 5.3 was used for meta-analysis. Heterogeneity was examined by sensitivity analysis, and subgroup analysis was performed. RESULTS: Five randomized controlled trials with 849 participants were included. The main components of multicomponent non-pharmacological interventions included enhancement of relevant training for healthcare professionals, intensive preoperative education and familiarity with ICU environment, postoperative sleep management, pain management, music therapy, cognitive stimulation, and full participation of family members. Meta-analysis showed that non-pharmacologic intervention reduced the overall incidence of postoperative delirium in oral cancer patients[RR=0.41, 95%CI:(0.31,0.54), I2=0%], decreased the duration of postoperative delirium [MD=-38.51, 95%CI:(-46.25,-30.77),I2=88%]. Subgroup analysis showed that non-pharmacologic intervention reduced the incidence of delirium on the first postoperative day[RR=0.37, 95%CI:(0.20,0.70), I2=0%], but had non-significant improvement in the incidence of delirium on the second and third postoperative day. Non-pharmacological interventions improved assessment of postoperative agitated sedation and quality of recovery. CONCLUSIONS: The current evidence shows that non-pharmacological interventions can reduce the overall incidence and duration of postoperative delirium, and improve agitated sedation and quality of recovery in oral cancer patients.
