Abstract

Introduction: Patients discharged from the intensive care unit (ICU) suffer from long-term symptoms affecting the physical, psychological, and cognitive well-being and cannot understand memories and dreams. Intensive care unit diaries describe daily events about the patient and may allow them to reconstruct their experience.

Objective: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to investigate the effects of ICU diaries on posttraumatic stress disorder (PTSD), depression, and anxiety.

Methods: Five electronic databases were searched up to May 6, 2022. We included RCTs comparing patients admitted to the ICU who received a diary to those who did not receive a diary. The primary outcome was the rate of PTSD. Secondary outcomes were rates of depression and anxiety.

Results: We included 7 RCTs. Patients who received a diary during the ICU admission had reduced rate of PTSD (78/432 [18%] vs 106/422 [25%]; risk ratio [RR], 0.73; 95% confidence interval [CI], 0.57-0.94; P = .02; I2 = 0%; trial sequential analysis-adjusted CI, 0.55-0.97) when compared with patients who did not receive a diary. We found a non-statistically significant difference toward a reduction in the rate of depression (38/232 [16%] vs 54/224 [24%]; RR, 0.70; 95% CI, 0.49-1.01; P = .06; I2 = 0%) and anxiety (63/232 [27%] vs 70/224 [31%]; RR, 0.64; 95% CI, 0.29-1.40; P = .26; I2 = 67%).

Conclusions: Providing an ICU diary to patients admitted to the ICU reduced the rate of PTSD symptoms compared with usual care.
