Purpose: The purpose of this study was to examine the effect of aromatherapy with an essential oil blend containing lavender, bergamot, ylang-ylang, and sweet orange, compared with placebo, on perceptions of anxiety in ICU RNs.
Methods: Nurses recruited from six adult ICUs and a neonatal ICU participated in this blinded, randomized, placebo-controlled study, which took place over a 30-day intervention period.
Results: Although there were no statistically significant changes in anxiety pre- to postintervention or between the intervention and placebo groups, there were also no adverse events or untoward effects.
Conclusion: The results of this study may support aromatherapy as an evidence-based strategy to reduce anxiety in ICU nurses. Additional research is needed.

Purpose: The use of patient/family-centred written summaries to supplement verbal information may be useful to improve knowledge and reduce anxiety related to patient transfer from the intensive care unit (ICU) to a hospital ward. We aimed to identify essential elements to include in an ICU-specific patient-oriented discharge summary tool (PODS-ICU).
Methods: We conducted a mixed methods study.

Background: Despite syntheses of evidence showing efficacy of music intervention for improving psychological and physiological outcomes in critically ill patients, interventions that include nonmusic sounds have not been addressed in reviews of evidence. It is unclear if nonmusic sounds in the intensive care unit (ICU) can confer benefits similar to those of music.
Objective: The aim of this study was to summarise and contrast available evidence on the effect of music and nonmusic sound interventions for the physiological and psychological outcomes of ICU patients based on the results of randomised controlled trials.

Background: Experiencing a critical illness may be a stressful life event that is also associated with cognitive dysfunction during and after the intensive care unit (ICU) stay. A deep-tech solution based on non-immersive virtual reality, gamification and motion capture called Rehabilitation Gaming System for Intensive Care Units (RGS-ICU) has been developed that includes both cognitive stimulation and relaxation protocols specifically designed for patients with critical illness. This study aims to evaluate whether the cognitive and relaxation protocols of the RGS-ICU platform are 1) effective in improving neuropsychological outcomes during and after ICU stay and 2) safe for patients with critical illness.

Background: Experiencing a loved one's stay in the intensive care unit (ICU) can profoundly affect families, often leading to post-intensive care syndrome-family (PICS-F), a condition particularly exacerbated during the COVID-19 pandemic. While PICS-F significantly impacts the mental health of families of ICU patients, especially in the context of COVID-19, the long-term effects beyond 12 months remain understudied. This study aims to explore the prevalence of PTSD-related symptoms and health-related quality of life (HRQOL) in family members up to 18 months after ICU discharge.
