Intensive care unit interventions to improve quality of dying and death: scoping review

Abstract

BackgroundIntensive care units (ICUs) have mortality rates of 10%–29% owing to illness severity. Postintensive care syndrome-family affects bereaved relatives, with a prevalence of 26% at 3 months after bereavement, increasing the risk for anxiety and depression. Complicated grief highlights issues such as family presence at death, inadequate physician communication and urgent improvement needs in end-of-life care. However, no study has comprehensively reviewed strategies and components of interventions to improve end-of-life care in ICUs.AimThis scoping review aimed to analyse studies on improvement of the quality of dying and death in ICUs and identify interventions and their evaluation measures and effects on patients.MethodsMEDLINE, CINAHL, PsycINFO and Central Journal of Medicine databases were searched for relevant studies published until December 2023, and their characteristics and details were extracted and categorised based on the Joanna Briggs model.ResultsA total of 24 articles were analysed and 10 intervention strategies were identified: communication skills, brochure/leaflet/pamphlet, symptom management, intervention by an expert team, surrogate decision-making, family meeting/conference, family participation in bedside rounds, psychosocial assessment and support for family members, bereavement care and feedback on end-on-life care for healthcare workers. Some studies included alternative assessment by family members and none used patient assessment of the intervention effects.ConclusionThis review identified 10 intervention strategies to improve the quality of dying and death in ICUs. Many studies aimed to enhance the quality by evaluating the outcomes through proxy assessments. Future studies should directly assess the quality of dying process, including symptom evaluation of the patients.
