Psychosocial Support Interventions for Adult Critically Ill Patients During the Acute Phase of Their ICU Stay: A Scoping Review.

: Addressing Intensive Care Unit (ICU) patients' psychological well-being is crucial, yet psychosocial support interventions that can facilitate effective coping, ultimately decreasing stress-related physiological, mental health, and cognitive sequelae, are not currently included in clinical practice guidelines and standards. : To identify and synthesize research evidence on psychosocial support interventions in the ICU, including types of outcomes and measures of effectiveness, and to explore research gaps and barriers to implementation. : The review was directed by a protocol based on current guidance for scoping reviews. The quality of studies was assessed using the National Institute for Health and Clinical Excellence. The review focused on articles containing evaluations of psychosocial interventions through an experimental or quasi-experimental design or pretest-posttest comparisons. Databases searched included Medline, CINAHL, PubMed, PsychInfo, and the Cochrane Library. : Ten highly heterogeneous studies were identified, encompassing diverse interventions (e.g., relaxation, psychotherapy, spirituality, and positive suggestions) and patient populations. Across the 10 studies, no intervention type was replicated, and most samples were small and quasi-experimental, limiting internal validity and preventing quantitative synthesis. Despite these limitations, the evidence reviewed supports that various psychosocial interventions, including positive suggestions (constructive, reassuring thoughts), relaxation techniques, psychotherapy (emotional, behavioral guidance), and spiritual and/or religious support can alleviate psychological sequelae, such as depression, anxiety, and Post Traumatic Stress in ICU patients. : This review highlights the positive impact of psychosocial interventions on alleviating psychological distress in ICU patients. However, a critical gap exists in understanding their effects on other clinical and physiological outcomes, necessitating comprehensive research.
