Crit Care Resusc
-
Background: Persistent psychological distress occurs frequently in family members of patients who die in an intensive care unit (ICU). Objective: To determine the effectiveness of bereavement interventions in reducing persisting psychological distress in bereaved family members after death in an adult ICU. Design: Systematic review and meta-analysis of studies that assessed the effect of bereavement interventions on persisting psychological distress in bereaved family members of ICU patients. ⋯ Scores for Impact of Event Scale, Impact of Event Scale-Revised and Inventory of Complicated Grief were measured in some but not all studies. There was no effect of an intervention on HADS scores (weighted mean difference, -0.79 [95% confidence interval, -3.81 to 2.23]; I2 = 65.8%). Conclusions: Owing to limited data, and clinical and statistical heterogeneity, there is considerable uncertainty regarding whether bereavement support strategies reduce, increase or have no effect on psychological distress in bereaved family members.
