Abstract: Objective: To evaluate the effects of ICU diary on post-traumatic stress disorder, anxiety and depression in critically ill patients. Methods: Studies investigating the effects of ICU diary on post-traumatic stress disorder, anxiety and depression with RCT design were searched from eight databases, including PubMed, Embase, Cochrane Library, Web of Science, CBM, CNKI, Wanfang and VIP from inception to September 11th, 2019. Two researchers independently screened and evaluated the literature and extracted the data. Meta-analysis was conducted by RevMan 5.3. Results: Seven studies with a total of 702 patients were included in the meta-analysis. The results showed that ICU diary, which was recorded by medical staffs or family members during patients' hospitalization in ICU, could significantly decrease the incidence of Post-Traumatic Stress Disorder [OR=0.58, 95%CI (0.36-0.93), Z=2.24, P=0.03], anxiety [OR=0.24, 95%CI (0.10-0.60), Z=3.07, P=0.002] and depression [OR=0.29, 95%CI (0.11-0.79), Z=2.43, P=0.01] in patients after discharge. Conclusion: ICU diary is shown to reduce the incidence of Post-Traumatic Stress Disorder, anxiety and depression of patients after discharge. More high-quality studies with RCT design are needed to verify these effects.
