Positive communication for decreasing burnout in intensive-care-unit staff: a cluster-randomized trial

Intensive Care Medicine Published: 30 October 2025

Purpose

Occupational burnout is common among intensive-care-unit (ICU) staff and adversely affects staff well-being and patient care. We hypothesized that a multicomponent intervention based on organizational support and workplace climate improvement would reduce burnout.

Methods

The 1:1 cluster-randomized Hello trial involved 370 ICUs from sixty countries allocated to either the intervention or usual care. The four-week intervention designed to promote a positive workplace culture and within-team support used posters, email nudges, greetings during morning meetings, role modeling, and positive messages in boxes and on noticeboards. The primary endpoint was burnout prevalence, measured using the Maslach Burnout Inventory. Secondary outcomes included MBI subscale scores, well-being, job satisfaction, ethical climate, intention to leave, work safety, and professional conflicts.

Results

Before the intervention, burnout prevalence was 59.4% (95% CI, 58.6–60.5), with no difference between arms. After the intervention, 4966 intervention-arm and 4602 control-arm healthcare professionals completed the MBI. Burnout prevalence was significantly lower in the intervention arm relative to controls (52.2% vs. 63.3%; adjusted odds ratio, 0.56; 95%CI 0.46–0.68; P < 0.001). Among MBI sub-scales scores, emotional exhaustion and depersonalization were lower, and personal accomplishment was higher in the intervention arm. Staff in the intervention arm reported better job satisfaction, workplace safety, ethical climate, and patient- and family-centered care; they were less often considering a job change.

Conclusions

The Hello intervention reduced burnout and improved workplace culture among ICU staff. Given the pragmatic design, the intervention tested may have broad applicability.

 

 

 

 

Long-term effects of flexible visitation in the intensive care unit on family members’ mental health: 12-month results from a randomized clinical trial

Intensive Care Medicine, Published: 22 August 2024

Purpose

The aim of this study was to assess the effects of flexible intensive care unit (ICU) visitation on the 1-year prevalence of post-traumatic stress, anxiety and depression symptoms among family members of critically ill patients.

Methods

This is a long-term outcome analysis of a cluster-crossover randomized clinical trial that evaluated a flexible visitation model in the ICU (12 h/day) compared to a restrictive visitation model (median 1.5 h/day) in 36 Brazilian ICUs. In this analysis, family members were assessed 12 months after patient discharge from the ICU for the following outcomes: post-traumatic stress symptoms measured by the Impact Event Scale-6 and anxiety and depression symptoms measured by the Hospital Anxiety and Depression Scale.

Results

A total of 519 family members were analyzed (288 in the flexible visitation group and 231 in the restrictive visitation group). Three-hundred sixty-nine (71.1%) were women, and the mean age was 46.6 years. Compared to family members in the restrictive visitation group, family members in the flexible visitation group had a significantly lower prevalence of post-traumatic stress symptoms (21% vs. 30.5%; adjusted prevalence ratio [aPR], 0.91; 95% confidence interval [CI] 0.85–0.98; p = 0.01). The prevalence of anxiety (28.9% vs. 33.2%; aPR 0.93; 95% CI 0.72–1.21; p = 0.59) and depression symptoms (19.2% vs. 25%; aPR, 0.78; 95% CI 0.60–1.02; p = 0.07) did not differ significantly between the groups.

Conclusion

Flexible ICU visitation, compared to the restrictive visitation, was associated with a significant reduction in the 1-year prevalence of post-traumatic stress symptoms in family members.

Mental health outcomes of ICU and non-ICU healthcare workers during the COVID-19 outbreak: a cross-sectional study

Background

Intensive care workers are known for their stressful work environment and for a high prevalence of mental health outcomes. The aim of this study was to evaluate the mental health, well-being and changes in lifestyle among intensive care unit (ICU) healthcare workers (HCW) during the first wave of the COVID-19 pandemic and to compare these results with those of HCW in other hospital units. Another objective was to understand which associated factors aggravate their mental health during the COVID-19 outbreak.

Methods

This cross-sectional survey collected socio-demographic data, lifestyle changes and mental health evaluations as assessed by the Generalized Anxiety Disorder 7 items (GAD-7), the Patient Health Questionnaire 9 items (PHQ-9), the Peritraumatic Distress Inventory (PDI) and the World Health Organization Well-Being Index (WHO-5) from the 28th May to 7th July 2020. The study was carried out at Geneva University Hospitals, a group of eight public hospitals in Switzerland. ICU HCW were analyzed for mental health outcomes and lifestyles changes and then compared to non-ICU HCW. A series of linear regression analyses were performed to assess factors associated with mental health scores.

Results

A total of 3461 HCW were included in the study, with 352 ICU HCW. Among ICU HCW, 145 (41%) showed low well-being, 162 (46%) symptoms of anxiety, 163 (46%) symptoms of depression and 76 (22%) had peritraumatic distress. The mean scores of GAD-7, PHQ-9 and WHO-5 were worse in ICU HCW than in non-ICU HCW (p < 0.01). Working in the ICU rather than in other departments resulted in a change of eating habits, sleeping patterns and alcohol consumption (p < 0.01). Being a woman, the fear of catching and transmitting COVID-19, anxiety of working with COVID-19 patients, work overload, eating and sleeping disorders as well as increased alcohol consumption were associated with worse mental health outcomes.

Conclusion

This study confirms the suspicion of a high prevalence of anxiety, depression, peritraumatic distress and low well-being during the first COVID-19 wave among HCW, especially among ICU HCW. This allows for the identification of associated risk factors. Long-term psychological follow-up should be considered for HCW.

Long-Term Mental Health Problems After Delirium in the ICU

Long-Term Mental Health Problems After Delirium in the ICU

Wolters, A et al

Critical Care Medicine October 2016 - Volume 44 - Issue 10 - p 1808–1813

Objectives: To determine whether delirium during ICU stay is associated with long-term mental health problems defined as symptoms of anxiety, depression, and posttraumatic stress disorder. Design: Prospective cohort study. Setting: Survey study, 1 year after discharge from a medical-surgical ICU in the Netherlands. Patients: One-year ICU survivors of an ICU admission lasting more than 48 hours, without a neurologic disorder or other condition that would impede delirium assessment during ICU stay. Interventions: None. 
Measurements and Main Results: One year after discharge, ICU survivors received a survey containing the Hospital Anxiety and Depression Scale with a subscale for symptoms of depression and a subscale for symptoms of anxiety, and the Impact of Event Scale 15 item measuring symptoms of posttraumatic stress disorder. Participants were classified as having experienced no delirium (n = 270; 48%), a single day of delirium (n = 86; 15%), or multiple days of delirium (n = 211; 37%) during ICU stay. Log-binomial regression was used to assess the association between delirium and symptoms of anxiety, depression, and posttraumatic stress disorder. The study population consisted of 567 subjects; of whom 246 subjects (43%) reported symptoms of anxiety (Hospital Anxiety and Depression Scale with a subscale for anxiety, ≥ 8), and 254 (45%) symptoms of depression (Hospital Anxiety and Depression Scale with a subscale for depression, ≥ 8). In 220 patients (39%), the Impact of Event Scale 15 item was greater than or equal to 35, indicating a high probability of posttraumatic stress disorder. There was substantial overlap between these mental health problems—63% of the subjects who scored positive for the presence of any three of the mental health problems, scored positive for all three. No association was observed between either a single day or multiple days of delirium and symptoms of anxiety, depression, or posttraumatic stress disorder. 
Conclusions: Although symptoms of anxiety, depression, and posttraumatic stress disorder were found to be common 1 year after critical illness, the occurrence of delirium during ICU stay did not increase the risk of these long-term mental health problems.
