A longitudinal investigation of posttraumatic stress and depressive symptoms over the course of the year following medical-surgical intensive care unit admission

Factors Influencing Stress Disorders in Intensive Care Unit (ICU) Patients After Liver Transplantation: A Cross-Sectional Study

BACKGROUND Evidence on psychological factors associated with post-transplant post-traumatic stress disorder (PTSD) in liver transplantation (LT) patients is limited. Identifying the psychological factors associated with post-transplant PTSD would help to understand the symptoms of PTSD and take preventive measures. The aim of this study was to investigate factors influencing stress disorders in Intensive Care Unit (ICU) patients 1 year after LT. MATERIAL AND METHODS We assessed data from 184 LT patients at our hospital between January 2020 and December 2022. According to the PCL-C score, the patients were divided into the PTSD group (score ≤37) and the non-PTSD group (score >37). The demographic data, clinical data, the pain visual analogue scale (VAS), the anxiety and depression scale (HADS), and the psychological resilience scale (CD-RISC score) were compared between the 2 groups. Pearson correlation analysis was used to analyze the correlation between PCL-C and VAS, HADS, and CD-RISC, and logistic regression was used to analyze the factors influencing PTSD. SPSS 23.0 software was used for statistical analysis. RESULTS The average age of the 184 participants was 53.17 years (±3.47) and 66.85% of the subjects were male. The prevalence rate of post-transplant PTSD was 22.83% and the total score on the PCL-C scale was 32.47±7.81. Pearson correlation analysis showed that PCL-C score was positively correlated with VAS (r=0.312, P=0.012) and HADS (r=0.412, P<0.001), and negatively correlated with CD-RISC (r=-0.468, P<0.001). Logistic regression analysis showed that the symptom of post-transplant PTSD was significantly associated with higher VAS (OR=1.058, P=0.007) and HADS (OR=1.885, P<0.001) scores and lower CD-RISC (OR=2.213, P<0.001) score, which indicated that higher VAS and HAD scores were risk factors that contributed to PTSD and lower CD-RISC was a protective factor against PTSD. CONCLUSIONS We found that pain, anxiety, depression, and resilience were associated with symptoms of PTSD in LT patients in the ICU. Nursing staff should seek to relieve their patients' pain and assure provision of targeted health education and personalized psychological counseling to reduce the risk of PTSD after LT.

Quality of life in ICU survivors and their relatives with post-intensive care syndrome: A systematic review

BACKGROUND

Post-intensive care syndrome (PICS) is characterized by all three adverse survivorship dimensions: physical function, cognitive function and mental health status.

AIM

This review aimed to describe the quality of life (QoL) of Intensive Care Unit (ICU) survivors with PICS after discharge and of their relatives with Family Post-intensive care syndrome (PICS-F) and to report anxiety, depression and Post-Traumatic Stress Disorders (PTSD) in studies investigating PICS.

STUDY DESIGN

A systematic review was carried out. We searched PubMed, Scopus, Web of Science and the Cumulative Index to Nursing and Allied Health Literature. This review was registered in the PROSPERO database (CRD42022382123).

RESULTS

We included 19 studies of PICS and PICS-F in this systematic review. Fourteen observational studies report the effects of PICS on depression, 12 studies on anxiety and nine on post-traumatic stress disorder and 10 on QoL. Mobility, personal care, usual activities and pain/discomfort in QoL were the domains most affected by PICS. A significant association was demonstrated between a high level of ICU survivors' anxiety and high levels of ICU relatives' burden. Strain-related symptoms and sleep disorders were problems encountered by ICU relatives with PICS-F.

CONCLUSION

PICS and PICS-F were widespread experiences among ICU survivors and their ICU relatives, respectively. The results of this review showed the adverse effects of PICS and PICS-F on QoL.

RELEVANCE TO CLINICAL PRACTICE

PICS and PICS-F strongly impact the rehabilitation process and are measured in terms of health costs, financial stress and potentially preventable readmission.

Depressive symptoms over time among survivors after critical illness: A systematic review and meta-analysis

OBJECTIVE

Critical illness survivors frequently experience various degrees of depressive symptoms, which hinder their recovery and return to daily life. However, substantial variability in the prevalence of depressive symptoms has been reported among critical illness survivors. The exact prevalence remains uncertain.

METHODS

A systematic search was performed in PubMed, Embase, CINAHL, and PsycINFO from inception to August 2023 for observational studies that reported depressive symptoms in adult critical illness survivors. The random-effects model was used to estimate the prevalence of depressive symptoms. Subgroup analysis and meta-regression were conducted to explore potential moderators of heterogeneity. Study quality was evaluated using the Joanna Briggs Institute's tool and the GRADE approach.

RESULTS

Fifty-two studies with 24,849 participants met the inclusion criteria. Overall prevalence estimate of depressive symptoms was 21.1% (95% CI, 18.3-24.1%). The prevalence of depressive symptoms remains stable over time. Point prevalence estimates were 21.3% (95% CI, 9.9-35.4%), 19.9% (95% CI, 14.6-25.9%), 18.5% (95% CI, 9.6-29.2%), 21.0% (95% CI, 16.8-25.5%), and 22.6% (95% CI, 14.4-31.8%) at <3, 3, 6, 12, and > 12 months after discharge from intensive care unit (ICU), respectively.

CONCLUSIONS

Depressive symptoms may impact 1 in 5 adult critically ill patients within 1 year or more following ICU discharge. An influx of rehabilitation service demand is expected, and risk stratification to make optimal clinical decisions is essential. More importantly, to propose measures for the prevention and improvement of depressive symptoms in patients after critical care, given the continuous, dynamic management of ICU patients, including ICU stay, transition to general wards, and post-hospital.

Long-term outcomes of patients supported with extracorporeal membrane oxygenation for acute respiratory distress syndrome: a systematic review and meta-analysis

BACKGROUND

Extracorporeal membrane oxygenation (ECMO) is increasingly used to support patients with severe acute respiratory distress syndrome (ARDS). The impact of ECMO on long-term outcomes of patients with severe ARDS is unclear.

METHODS

We searched electronic databases from inception to January 17th 2023. We selected clinical trials and observational studies reporting on long-term outcomes of patients supported with ECMO for ARDS. Health-related quality of life (HRQoL) was the primary outcome. Secondary outcomes included cognitive function, mental health, functional status, respiratory symptoms, and return to work.

RESULTS

Of the 7126 screened citations, 1 randomized clinical trial and 31 observational studies were included, of which 7 compared conventional mechanical ventilation (CMV) and ECMO. Overall quality of studies of the included studies was limited, with the majority being either low (45%) or fair (32%) quality. There was no significant difference in HRQoL measured with the SF-36 score between ECMO and CMV patients (physical component score [PCS]: mean difference 3.91 (- 6.22 to 14.05), mental component score [MCS] mean difference 1.33 (- 3.93 to 6.60)). There was no difference between cognitive function, mental health, functional status, and respiratory symptoms between ECMO and CMV, but data available for comparison were limited. There were high rates of disability for ECMO survivors with 49% of patients returning to work and 23% needing assistance at home on follow-up.

CONCLUSION

Survivors of ECMO for ARDS experience significant disability in multiple domains. Further studies are needed to examine the effect of ECMO on long-term outcomes of patients compared to CMV.

Mixed-methods randomised study exploring the feasibility and acceptability of eye-movement desensitisation and reprocessing for improving the mental health of traumatised survivors of intensive care following hospital discharge: protocol

INTRODUCTION

Post-traumatic symptoms are common among patients discharged from intensive care units (ICUs), adversely affecting well-being, increasing healthcare utilisation and delaying return to work. Non-pharmacological approaches (eg, music, therapeutic touch and patient diaries) have been suggested as candidate interventions and trauma-focused psychological interventions have been endorsed by international bodies. Neither category of intervention is supported by definitive evidence of long-term clinical effectiveness in patients who have been critically ill. This study assesses the feasibility and acceptability of using eye-movement desensitisation and reprocessing (EMDR) to improve the mental health of ICU survivors.

METHODS AND ANALYSIS

EMERALD is a multicentre, two-part consent, pilot feasibility study, recruiting discharged ICU survivors from three hospitals in the UK. We are gathering demographics and measuring post-traumatic symptoms, anxiety, depression and quality of life at baseline. Two months after discharge, participants are screened for symptoms of post-traumatic stress disorder (PTSD) using the Impact of Events Scale-Revised (IES-R). Patients with IES-R scores<22 continue in an observation arm for 12 month follow-up. IES-R scores≥22 indicate above-threshold PTSD symptoms and trigger invitation to consent for part B: a randomised controlled trial (RCT) of EMDR versus usual care, with 1:1 randomisation. The study assesses feasibility (recruitment, retention and intervention fidelity) and acceptability (through semistructured interviews), using a theoretical acceptability framework. Clinical outcomes (PTSD, anxiety, depression and quality of life) are collected at baseline, 2 and 12 months, informing power calculations for a definitive RCT, with quantitative and qualitative data convergence guiding RCT refinements.

ETHICS AND DISSEMINATION

This study has undergone external expert peer review and is funded by the National Institute for Health and Care Research (grant number: NIHR302160). Ethical approval has been granted by South Central-Hampshire A Research Ethics Committee (IRAS number: 317291). Results will be disseminated through the lay media, social media, peer-reviewed publication and conference presentation.

Anxiety and depression in intensive care patients six months after admission to an intensive care unit: A cohort study

OBJECTIVES

To measure the prevalence of anxiety and depression in intensive care patients six months after admission to an intensive care unit and to investigate which variables are associated with anxiety and depression at six months.

RESEARCH METHODOLOGY

In this cohort study, patient-reported outcome measures were collected as soon as possible upon admission and at six months. Two logistic regression models were performed to examine variables associated with reporting anxiety and depression above ≥8 at six months.

SETTING

Patients were recruited from six intensive care units in two Norwegian hospitals between 2018 and 2020.

MAIN OUTCOME MEASURES

The Hospital Anxiety and Depression Scale.

RESULTS

A total of 145 patients was included in the study. The patients reported a prevalence of 18.6% (n = 27) and 12.4% (n = 18) of anxiety and depression, respectively. Higher baseline anxiety scores were associated with both higher odds of reporting anxiety and depression above ≥8. Younger age was associated with higher odds of reporting anxiety, and being female was associated with lower odds of reporting depression.

CONCLUSION

Several intensive care survivors reported having symptoms of anxiety and depression six months after admission to the intensive care unit. Younger age, and higher anxiety scores at baseline were variables associated with higher odds of reporting symptoms of either anxiety or depression, while being female was associated with a lower odds of reporting depression.

IMPLICATIONS FOR CLINICAL PRACTICE

Screening patients for anxiety and depression may help to identify vulnerable patients. Structured follow-ups with intensive care nurses in an outpatient setting may be useful to help patients to work through some of the experiences from the intensive care unit.

Symptom Assessment for Mechanically Ventilated Patients: Principles and Priorities: An Official American Thoracic Society Workshop Report

Mechanically ventilated patients experience many adverse symptoms, such as anxiety, thirst, and dyspnea. However, these common symptoms are not included in practice guideline recommendations for routine assessment of mechanically ventilated patients. An American Thoracic Society-sponsored workshop with researchers and clinicians with expertise in critical care and symptom management was convened for a discussion of symptom assessment in mechanically ventilated patients. Members included nurses, physicians, a respiratory therapist, a speech-language pathologist, a critical care pharmacist, and a former intensive care unit patient. This report summarizes existing evidence and consensus among workshop participants regarding 1) symptoms that should be considered for routine assessment of adult patients receiving mechanical ventilation; 2) key symptom assessment principles; 3) strategies that support symptom assessment in nonvocal patients; and 4) areas for future clinical practice development and research. Systematic patient-centered assessment of multiple symptoms has great potential to minimize patient distress and improve the patient experience. A culture shift is necessary to promote ongoing holistic symptom assessment with valid and reliable instruments. This report represents our workgroup consensus on symptom assessment for mechanically ventilated patients. Future work should address how holistic, patient-centered symptom assessment can be embedded into clinical practice.

Awareness With Paralysis Among Critically Ill Emergency Department Patients: A Prospective Cohort Study

OBJECTIVES

In mechanically ventilated patients, awareness with paralysis (AWP) can have devastating consequences, including post-traumatic stress disorder (PTSD), depression, and thoughts of suicide. Single-center data from the emergency department (ED) demonstrate an event rate for AWP factors higher than that reported from the operating room. However, there remains a lack of data on AWP among critically ill, mechanically ventilated patients. The objective was to assess the proportion of ED patients experiencing AWP and investigate modifiable variables associated with its occurrence.

DESIGN

An a priori planned secondary analysis of a multicenter, prospective, before-and-after clinical trial.

SETTING

The ED of three academic medical centers.

PATIENTS

Mechanically ventilated adult patients that received neuromuscular blockers.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

All data related to sedation and analgesia were collected. AWP was the primary outcome, assessed with the modified Brice questionnaire, and was independently adjudicated by three expert reviewers. Perceived threat, in the causal pathway for PTSD, was the secondary outcome. A total of 388 patients were studied. The proportion of patients experiencing AWP was 3.4% ( n = 13), the majority of whom received rocuronium ( n = 12/13; 92.3%). Among patients who received rocuronium, 5.5% ( n = 12/230) experienced AWP, compared with 0.6% ( n = 1/158) among patients who did not receive rocuronium in the ED (odds ratio, 8.64; 95% CI, 1.11-67.15). Patients experiencing AWP had a higher mean ( sd ) threat perception scale score, compared with patients without AWP (15.6 [5.8] vs 7.7 [6.0]; p < 0.01).

CONCLUSIONS

AWP was present in a concerning proportion of mechanically ventilated ED patients, was associated with rocuronium exposure in the ED, and led to increased levels of perceived threat, placing patients at greater risk for PTSD. Studies that aim to further quantify AWP in this vulnerable population and eliminate its occurrence are urgently needed.

Symptom experiences of critically-ill hematologic malignancy patients: A scoping review

CONTEXT

Critically-ill patients with hematologic malignancies are increasingly admitted to intensive care units globally. Unrelieved symptoms during intensive care treatment may contribute to poor outcomes.

OBJECTIVE

To better understand the symptom experience(s) for critically-ill patients with hematologic malignancies.

METHODS

A scoping review was conducted searching Medline, CINAHL, PychInfo, Embase, and ProQuest databases, the Cochrane Library, and the grey literature between January 1st, 1990 and July 15th, 2020. Two authors independently reviewed articles for inclusion and verified abstracted data.

RESULTS

Seventeen articles met inclusion criteria, including 11 cohort studies, 1 case-control study, and five review articles. No qualitative or mixed-method studies were retrieved. Symptoms were reported as the primary outcome across two studies (17%). Reported hematologic malignancy subtypes included leukemia and/or myelodysplastic syndrome (9, 53%), lymphoma (8, 47%), multiple myeloma (7, 41%), and aplastic anemia (2, 12%). The principal indication for ICU admission was respiratory failure, followed by cardiogenic shock/cardiac failure, endocrine disturbances, sepsis, and neurological failure. Only one study used validated tools for evaluating symptoms. Thirty-four symptoms were reported: altered level of consciousness/coma (35%); diarrhea (35%); nausea (35%); dyspnea (35%); vomiting (29%); and pain (29%). Two articles (13%) identified symptom clusters.

CONCLUSION

There is minimal research that measures and explores the symptom experiences of critically-ill patients with hematologic malignancies. New research in this domain is needed to inform targeted symptom care for this vulnerable patient population.

Prevalence of post-traumatic stress disorder and its predictors following coronary artery bypass graft surgery

BACKGROUND

Cardiac surgery can be traumatic and stressful, and as a result many people experience psychological difficulties following treatment.

AIM

To assess the level of post-traumatic stress disorder (PTSD) 1 month after coronary artery bypass graft (CABG) surgery among Jordanian patients, and to examine the predictors of PTSD after 1 month.

METHOD

A descriptive survey design was used.

FINDINGS

149 patients participated in the study. Their mean age was 59 years (SD=10.2) and most were male (87%) and married (93%). Some 44% of patients had PTSD. Length of stay in hospital (c² (1)=6.598, P<0.05), and age (c² (1)=4.920, P<0.05), predicted the occurrence of PTSD after 1 month.

CONCLUSIONS

Nurses, who are usually in the frontline with patients, should consider using a robust tool and clinical interview to assess and evaluate the presence and the risks of PTSD to promote early detection and optimal management. Follow-up studies after 6 and 12 months would be beneficial.

New Physical, Mental, and Cognitive Problems 1 Year after ICU Admission: A Prospective Multicenter Study

Rationale: Comprehensive studies addressing the incidence of physical, mental, and cognitive problems after ICU admission are lacking. With an increasing number of ICU survivors, an improved understanding of post-ICU problems is necessary. Objectives: To determine the occurrence and cooccurrence of new physical, mental, and cognitive problems among ICU survivors 1 year after ICU admission, their impact on daily functioning, and risk factors associated with 1-year outcomes. Methods: Prospective multicenter cohort study, including ICU patients ⩾16 years of age, admitted for ⩾12 hours between July 2016 and June 2019. Patients, or proxies, rated their health status before and 1 year after ICU admission using questionnaires. Measurements and Main Results: Validated questionnaires were used to measure frailty, fatigue, new physical symptoms, anxiety and depression, post-traumatic stress disorder, cognitive impairment, and quality of life. Of the 4,793 patients included, 2,345 completed the questionnaires both before and 1 year after ICU admission. New physical, mental, and/or cognitive problems 1 year after ICU admission were experienced by 58% of the medical patients, 64% of the urgent surgical patients, and 43% of the elective surgical patients. Urgent surgical patients experienced a significant deterioration in their physical and mental functioning, whereas elective surgical patients experienced a significant improvement. Medical patients experienced an increase in symptoms of depression. A significant decline in cognitive functioning was experienced by all types of patients. Pre-ICU health status was strongly associated with post-ICU health problems. Conclusions: Overall, 50% of ICU survivors suffer from new physical, mental, and/or cognitive problems. An improved insight into the specific health problems of ICU survivors would enable more personalized post-ICU care.

Grip Strength Correlates with Mental Health and Quality of Life after Critical Care: A Retrospective Study in a Post-Intensive Care Syndrome Clinic

Post-intensive care syndrome (PICS) is characterized by several prolonged symptoms after critical care, including physical and cognitive dysfunctions as well as mental illness. In clinical practice, the long-term follow-up of PICS is initiated after patients have been discharged from the intensive care unit, and one of the approaches used is a PICS clinic. Although physical dysfunction and mental illness often present in combination, they have not yet been examined in detail in PICS patients. Grip strength is a useful physical examination for PICS, and is reported to be associated with mental status in the elderly. We herein investigated the relationship between grip strength and the mental status using data from our PICS clinic. We primarily aimed to analyze the correlation between grip strength and the Hospital Anxiety and Depression Scale (HADS) score. We also analyzed the association between grip strength and the EuroQol 5 Dimension (EQ5D) score as quality of life (QOL). Subjects comprised 133 patients who visited the PICS clinic at one month after hospital discharge between August 2019 and December 2020. Total HADS scores were 7 (4, 13) and 10 (6, 16) (p = 0.029) and EQ5D scores were 0.96 (0.84, 1) and 0.77 (0.62, 0.89) (p ≤ 0.0001) in the no walking disability group and walking disability group, respectively. Grip strength negatively correlated with HADS and EQ5D scores. Correlation coefficients were r = -0.25 (p = 0.011) and r = -0.47 (p < 0.0001) for HADS and EQ5D scores, respectively. Grip strength was a useful evaluation that also reflected the mental status and QOL.

Exploring the Application of Interpretive Description in Chronic Illness: A Scoping Review

BACKGROUND AND PURPOSE

Chronic illness is a complex condition that affects over one billion people. To develop a deeper insight of the needs of this patient population, interpretive description uses disciplinary knowledge as the source of understanding. This methodology is a pragmatic approach to research without focusing on a strict methodological directive. The aims of this scoping review are twofold, (a) to describe the findings of studies that have used Thorne's interpretive description to research chronic illness and (b) to discuss the application of interpretive description in clinical research. Thereby, showing interpretive description as a valuable tool to advance nursing knowledge and patient care.

METHODS

The methodological framework for this review was based on the Johanna Briggs Institute guidelines for scoping reviews.

RESULTS

To develop an understanding of interpretive description, it is essential to examine the results of studies which have applied the methodology. Our scoping review showed that researchers utilizing interpretive description identified four common challenges experienced by individuals living with chronic illness: symptom management, education and knowledge, supportive care, and cultural disadvantages. By demonstrating how interpretive description is applied, it shows how it can be used to understand and interpret clinical phenomena to improve practice.

IMPLICATION FOR PRACTICE

This scoping review demonstrates how interpretive description was used to develop knowledge about chronic illness. The premise of interpretive description is that disciplinary knowledge offers a sufficient foundation to develop meaningful research to support health practices. By approaching research from a disciplinary perspective, new knowledge can be discovered to complex health problems.

Harming patients by provision of intensive care treatment: is it right to provide time-limited trials of intensive care to patients with a low chance of survival?

Time-limited trials of intensive care have arisen in response to the increasing demand for intensive care treatment for patients with a low chance of surviving their critical illness, and the clinical uncertainty inherent in intensive care decision-making. Intensive care treatment is reported by most patients to be a significantly unpleasant experience. Therefore, patients who do not survive intensive care treatment are exposed to a negative dying experience. Time-limited trials of intensive care treatment in patients with a low chance of surviving have both a small chance of benefiting this patient group and a high chance of harming them by depriving them of a good death. A 'rule of rescue' for the critically unwell does not justify time-limiting a trial of intensive care treatment and overlooks the experiential costs that intensive care patients face. Offering time-limited trials of intensive care to all patients, regardless of their chance of survival, overlooks the responsibility of resource-limited intensive care clinicians for suffering caused by their actions. A patient-specific risk-benefit analysis is vital when deciding whether to offer intensive care treatment, to ensure that time-limited trials of intensive care are not undertaken for patients who have a much higher chance of being harmed, rather than benefited by the treatment. The virtue ethics concept of human flourishing has the potential to offer additional ethical guidance to resource-limited clinicians facing these complex decisions, involving the balancing of a quantifiable survival benefit against the qualitative suffering that intensive care treatment may cause.

[Post-intensive care syndrome]

Post-intensive care syndrome is an entity defined in 2010 and covering any sequelae following an extended hospitalization in intensive care unit. It comprises psychological, cognitive and physical disorders (neuromyopathy, respiratory dysfunction, joint stiffness, among others). These sequelae have important consequences on autonomy and quality of life of these patients, as well as on their healthcare consumption and on mortality. Psychological sequelae can also be seen in hospitalized patients' relatives. Screening and management of these disorders is more and more frequent but no method has formally proven effective. The number of patients surviving an intensive care unit hospitalization is increasing, and management of post-intensive care syndrome is a major issue. It seems important that the internist be aware of this syndrome, given his pivotal role in global management of patients and frequent implication into care after the intensive care unit.

Physical, Mental, and Cognitive Health Status of ICU Survivors Before ICU Admission: A Cohort Study

OBJECTIVES

Although patient's health status before ICU admission is the most important predictor for long-term outcomes, it is often not taken into account, potentially overestimating the attributable effects of critical illness. Studies that did assess the pre-ICU health status often included specific patient groups or assessed one specific health domain. Our aim was to explore patient's physical, mental, and cognitive functioning, as well as their quality of life before ICU admission.

DESIGN

Baseline data were used from the longitudinal prospective MONITOR-IC cohort study.

SETTING

ICUs of four Dutch hospitals.

PATIENTS

Adult ICU survivors (n = 2,467) admitted between July 2016 and December 2018.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Patients, or their proxy, rated their level of frailty (Clinical Frailty Scale), fatigue (Checklist Individual Strength-8), anxiety and depression (Hospital Anxiety and Depression Scale), cognitive functioning (Cognitive Failure Questionnaire-14), and quality of life (Short Form-36) before ICU admission. Unplanned patients rated their pre-ICU health status retrospectively after ICU admission. Before ICU admission, 13% of all patients was frail, 65% suffered from fatigue, 28% and 26% from symptoms of anxiety and depression, respectively, and 6% from cognitive problems. Unplanned patients were significantly more frail and depressed. Patients with a poor pre-ICU health status were more often likely to be female, older, lower educated, divorced or widowed, living in a healthcare facility, and suffering from a chronic condition.

CONCLUSIONS

In an era with increasing attention for health problems after ICU admission, the results of this study indicate that a part of the ICU survivors already experience serious impairments in their physical, mental, and cognitive functioning before ICU admission. Substantial differences were seen between patient subgroups. These findings underline the importance of accounting for pre-ICU health status when studying long-term outcomes.

Early Detection of Patients at Risk of Developing a Post-Traumatic Stress Disorder After an ICU Stay

OBJECTIVES

To evaluate the diagnostic accuracy of the Impact Event Scale-Revisited assessed following ICU discharge to predict the emergence of post-traumatic stress disorder symptoms at 3 months.

DESIGN

Prospective cohort study.

SETTING

Three medical or surgical ICU of a French university hospital (Lyon, France).

PATIENTS

Patients greater than or equal to 18 years old, leaving ICU after greater than or equal to 2 nights of stay, between September 2017 and April 2018.

INTERVENTIONS

Patients completed the Impact Event Scale-Revisited and the Peritraumatic Dissociative Experiences Questionnaire within 8 days after ICU discharge and the Impact Event Scale-Revisited again at 3 months by phone. Patients having an Impact Event Scale-Revisited greater than or equal to 35 at 3 months were considered as having post-traumatic stress disorder symptoms.

MEASUREMENTS AND MAIN RESULTS

Among the 208 patients screened, 174 were included and 145 reassessed by phone at 3 months. Among the patients included at baseline, 43% presented symptoms of acute stress. At 3 months, 13% had an Impact Event Scale-Revisited greater than or equal to 35 and 17% had a score between 12 and 34. Regarding the performance of the Impact Event Scale-Revisited performed within 8 days after the ICU discharge to predict post-traumatic stress disorder symptoms at 3 months, the area under the curve was 0.90 (95% CI, 0.80-0.99), and an Impact Event Scale-Revisited greater than or equal to 12 had a sensitivity of 90%, a specificity of 71%, a positive predictive value of 32%, and a negative predictive value of 98%. History of anxiety disorder odds ratio = 3.7 (95% CI, 1.24-11.05; p = 0.02) and Impact Event Scale-Revisited greater than or equal to 12 odds ratio = 16.57 (95% CI, 3.59-76.46; p < 0.001) were identified as risk factors for post-traumatic stress disorder symptoms.

CONCLUSIONS

Impact Event Scale-Revisited assessed at ICU discharge has a good ability for the detection of patients at risk of developing post-traumatic stress disorder symptoms. Patients with history of anxiety disorder and those presenting acute stress symptoms at ICU discharge are more at risk to develop post-traumatic stress disorder symptoms.

Glucocorticoids and the Brain after Critical Illness

Treatment for critical illness typically focuses on a patient's short-term physical recovery; however, recent work has broadened our understanding of the long-term implications of illness and treatment strategies. In particular, survivors of critical illness have significantly elevated risk of developing lasting cognitive impairment and psychiatric disorders. In this review, we examine the role of endogenous and exogenous glucocorticoids in neuropsychiatric outcomes following critical illness. Illness is marked by acute elevation of free cortisol and adrenocorticotropic hormone suppression, which typically normalize after recovery; however, prolonged dysregulation can sometimes occur. High glucocorticoid levels can cause lasting alterations to the plasticity and structural integrity of the hippocampus and prefrontal cortex, and this mechanism may plausibly contribute to impaired memory and cognition in critical illness survivors, though specific evidence is lacking. Glucocorticoids may also exacerbate inflammation-associated neural damage. Conversely, current evidence indicates that glucocorticoids during illness may protect against the development of post-traumatic stress disorder. We propose future directions for research in this field, including determining the role of persistent glucocorticoid elevations after illness in neuropsychiatric outcomes, the role of systemic vs neuroinflammation, and probing unexplored lines of investigation on the role of mineralocorticoid receptors and the gut-brain axis. Progress toward personalized medicine in this area has the potential to produce tangible improvements to the lives patients after a critical illness, including Coronavirus Disease 2019.

Posttraumatic stress disorder prevalence in medical populations: A systematic review and meta-analysis

OBJECTIVE

PTSD is increasingly recognized following medical traumas although is highly heterogeneous. It is difficult to judge which medical contexts have the most traumatic potential and where to concentrate further research and clinical attention for prevention, early detection and treatment. The objective of this study was to compare PTSD prevalence in different medical populations.

METHODS

A systematic review of the literature on PTSD following medical traumas was conducted as well as a meta-analysis with final pooled result and 95% confidence intervals presented. A meta-regression was used to investigate the impact of potential effect modifiers (PTSD severity, age, sex, timeline) on study effect size between prevalence studies.

RESULTS

From 3278 abstracts, the authors extracted 292 studies reporting prevalence. Using clinician-administered reports, the highest 24 month or longer PTSD prevalence was found for intraoperative awareness (18.5% [95% CI=5.1%-36.6%]) and the lowest was found for epilepsy (4.5% [95% CI=0.2%-12.6%]). In the overall effect of the meta-regression, only medical events or procedures emerged as significant (p = 0.006) CONCLUSION: This review provides clinicians with greater awareness of medical contexts most associated with PTSD, which may assist them in the decision to engage in more frequent, earlier screening and referral to mental health services.

The ED-AWARENESS Study: A Prospective, Observational Cohort Study of Awareness With Paralysis in Mechanically Ventilated Patients Admitted From the Emergency Department

STUDY OBJECTIVE

Awareness with paralysis is a devastating complication for patients receiving mechanical ventilation and risks long-term psychological morbidity. Data from the emergency department (ED) demonstrate a high rate of longer-acting neuromuscular blocking agent use, delayed analgosedation, and a lack of sedation depth monitoring. These practices are discordant with recommendations for preventing awareness with paralysis. Despite this, awareness with paralysis has not been rigorously studied in the ED population. Our objective is to assess the prevalence of awareness with paralysis in ED patients receiving mechanical ventilation.

METHODS

This was a single-center, prospective, observational cohort study on 383 mechanically ventilated ED patients. After extubation, we assessed patients for awareness with paralysis by using the modified Brice questionnaire. Three expert reviewers independently adjudicated awareness with paralysis. We report the prevalence of awareness with paralysis (primary outcome); the secondary outcome was perceived threat, a mediator for development of posttraumatic stress disorder.

RESULTS

The prevalence of awareness with paralysis was 2.6% (10/383). Exposure to rocuronium at any point in the ED was significantly different between patients who experienced awareness with paralysis (70%) versus the rest of the cohort (31.4%) (unadjusted odds ratio 5.1; 95% confidence interval 1.30 to 20.1). Patients experiencing awareness with paralysis had higher mean values on the threat perception scale, denoting a higher degree of perceived threat, compared with patients who did not experience awareness with paralysis (13.4 [SD 7.7] versus 8.5 [SD 6.2]; mean difference 4.9; 95% confidence interval 0.94 to 8.8).

CONCLUSION

Awareness with paralysis occurs in a significant minority of ED patients who receive mechanical ventilation. Potential associations of awareness with paralysis with ED care and increased perceived threat warrant further evaluation.

Do-(Not-)Mechanical-Circulatory-Support Orders: Should We Ask All Cardiac Surgery Patients for Informed Consent for Post-Cardiotomy Extracorporeal Life Circulatory Support?

Post-cardiotomy extracorporeal life support (PC-ECLS) has seen a substantial increase in use over the past 10 years. PC-ECLS can be a life-saving procedure and is mostly applied in the presence of unexpected, severe cardio-respiratory complication. Despite PC-ECLS being critical in allowing for organ recovery, it is unfortunately closely connected with an unpredictable outcomes, high morbidity, and, even in the case of cardiac function improvement, potential sustained disabilities that have a life-changing impact for the patient and his or her family. Since the decision to start PC-ECLS is made in an acute setting, there is often only limited or no time for self-determined choices. Due to the major impact of the intervention, it would be highly desirable to obtain informed consent before starting PC-ECLS, since the autonomy of the patient and shared-decision making are two of the most important ethical values in modern medicine. Recent developments regarding awareness of the impacts of a prolonged intensive care stay make this a particularly relevant topic. Therefore, it would be desirable to develop a structural strategy that takes into account the likelihood of such an intervention and the wishes and preferences of the patient, and thus the related autonomy of the patient. This article proposes key points for such a strategy in the form of a PC-ECLS informed consent, a do-(not-)mechanical-circulatory-support order (D(N)MCS), and specific guidelines to determine the extent of the shared decision making. The concept presented in this article could be a starting point for improved and ethical PC-ECLS treatment and application.

Psychological morbidity a year after treatment in intensive care unit

Several studies have linked treatment in the Intensive Care Unit (ICU) with negative psychological outcomes. This study explores the prevalence of negative psychological outcomes in Greek patients (N=29), a year after treatment in ICU. Percentages of participants with anxiety [41%, 95% CI (22%, 60%)] and Post- Traumatic Stress Disorder (PTSD) [34%, 95% CI (16%, 53%)] symptoms were similar to the related literature. Percentages of participants with depressive [17%, 95% CI (3%, 32%)] symptoms were rather low. Only 10% of participants reported absence of quality of live issues. Anxiety symptoms were related to desire to talk about the ICU experience (p=0.010), duration of propofol administration (p=0.018) and loss of employment (p=0.019) and negatively related to duration of stay in the ICU (p=0.025). PTSD symptoms were related to experiencing other stressors during the year after the ICU stay (p=0.001), social constraint (p=0.003), duration of propofol administration (p=0.004), loss of employment (p=0.020), low income (p=0.022) and negative ICU memories (p=0.029). Depressive symptoms were related to loss of employment (p=0.003), low income (p=0.029) and social constraint (p=0.033). Patients experience elevated levels of psychological symptoms long after they are discharged from the hospital. Several psychosocial factors emerged as important factors to consider for predicting levels of distress.

Neuropsychological functioning in severe acute respiratory disorders caused by the coronavirus: Implications for the current COVID-19 pandemic

Objective: The coronavirus class of respiratory viruses - including Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19) - has been associated with central nervous system (CNS) disease. In fact, multiple mechanisms of CNS involvement have been proposed, making it difficult to identify a unitary syndrome that can be the focus of clinical work and research. Neuropsychologists need to understand the potential cognitive and psychological sequelae of COVID-19 and the impact of the interventions (e.g., ICU, ventilation) that have been used in treating patients with severe forms of the illness.Method: We briefly review the literature regarding the neurological and neuropsychological effects of similar coronaviruses, the limited information that has been published to date on COVID-19, and the literature regarding the long-term cognitive and psychological effects of undergoing treatment in the intensive care unit (ICU).Results: We discuss the roles that neuropsychologists can play in assessing and treating the cognitive difficulties and psychiatric symptoms described.Conclusions: At this time, the mechanisms, correlates, and effects of COVID-19 are poorly understood, but information gleaned from the literature on similar viruses and utilized interventions should help inform neuropsychologists as they begin to work with this population.

Sepsis survivor mice exhibit a behavioral endocrine syndrome with ventral hippocampal dysfunction

Severe acute stressors are known to trigger mood disorders in humans. Sepsis represents one such stressor, and survivors often suffer long term from psychiatric morbidity. We hypothesized that sepsis leads to lasting changes in neural circuits involved in stress integration, altering affective behavior and the stress response. To investigate this hypothesis, sepsis was induced in male C57Bl/6 mice using cecal ligation and puncture (CLP), and control mice underwent sham surgery. Mice recovered from acute illness within 2 weeks, after which they exhibited increased avoidance behavior and behavioral despair compared with sham, with behavioral changes observed more than 5 weeks after recovery. Sepsis survivors also showed evidence of enhanced hypothalamic-pituitary-adrenal (HPA) axis activity, with increased corticosterone after a novel stressor and increased adrenal weight. In the brain, sepsis survivor mice showed decreased stress-induced cfos mRNA and increased glucocorticoid receptor immunoreactivity specifically in the ventral hippocampus, a brain region known to coordinate emotional behavior and HPA axis activity. We conclude that murine sepsis survivors exhibit a behavioral neuroendocrine syndrome of negative affective behavior and HPA axis hyperactivity, which could be explained by ventral hippocampal dysfunction. These findings could contribute to our understanding of the human post-intensive care syndrome.

Psychological Sequelae in Family Caregivers of Critically III Intensive Care Unit Patients. A Systematic Review

Rationale: Family members of critically ill patients hospitalized in the intensive care unit (ICU) often become caregivers, and they are at risk to develop adverse psychological outcomes. There is a need to understand the psychological impact of critical illness on family caregivers. Objectives: The aim of this systematic review is to document the prevalence of depression, anxiety, and post-traumatic stress disorder (PTSD) in family caregivers of critically ill patients and identify potential risk factors for psychological outcomes to inform clinical and future research recommendations. Methods: A literature search for psychological outcomes for family caregivers of critically ill patients was conducted. A total of 1,148 studies from PsycINFO, CINAHL, Web of Science, SCOPUS, and Medline were identified. Results: Forty studies met inclusion criteria and were included in the review. The prevalence of psychological outcomes in family caregivers ranged from 4% to 94% for depression, 2% to 80% for anxiety, and 3% to 62% for PTSD. Caregiver depression, anxiety, and PTSD decreased in most studies that assessed longitudinal outcomes. Common risk factors identified for adverse psychological outcomes included younger caregiver age, caregiver relationship to the patient, lower socioeconomic status, and female sex. Conclusions: The prevalence of depression, anxiety, and PTSD varies greatly across studies of family caregivers of critically ill patients. This finding highlights the need for more systematic investigations of psychological outcomes and the implementation of clinical interventions to prevent or reduce depression, anxiety, and PTSD in family caregivers of critically ill patients.

Ambient Scent as a Positive Distraction in Long-Term Care Units: Theory of Supportive Design

AIM

This study was designed to explore the associations between an ambient scent environment and residents' wellness in long-term care facilities.

BACKGROUND

The number of older adults living in an institutional setting has been steadily but slowly increasing. Because of a higher chance of having psychological disorders among people living in institutional settings than people living in noninstitutional settings, providing a supportive institutional setting is critical to enhance their wellness. The theory of supportive design suggests healthcare facilities can lower people's stress levels via three conditions (i.e., perceived control, social support, and positive distractions).

METHOD

A single-blind and placebo-randomized controlled study investigated the impacts of ambient scent environment, as a positive distraction, on residents' depression levels. The recruited residents (N = 58) were randomly assigned into either the intervention group, which received a 1% dilution of lavender scent for 2 weeks nearby their bedside or the placebo group, which received a nonscent for 2 weeks.

RESULTS

Their depression levels were measured by the Geriatric Depression Scale. Based on the t tests, both intervention and placebo groups had improvement in depression, indicating a placebo effect of lavender scent. Further regression analyses explored the interaction effects of built environments (e.g., building, distance to a ventilation system, and square footage). However, no statistically significant impact of the built environment was found.

CONCLUSION

Despite a placebo effect of ambient scent environment and nonsignificant built environment on depression, this study has valuable implications of being a positive distraction during the healing process as developed by the Theory of Supportive design.

Experiencias de pacientes con discapacidades funcionales posteriores al tratamiento en la Unidad de Cuidados Intensivos

Introducción: Comprender las experiencias de los pacientes con discapacidades funcionales después del tratamiento en la Unidad de Cuidados Intensivos a su regreso a casa. Materiales y métodos: Se trata de un estudio de enfoque cualitativo que utilizó el estudio de caso como método de investigación. La muestra de ocho participantes fue compuesta intencionalmente y cerrada por saturación teórica. La recolección de datos se realizó a través de entrevistas domiciliarias semiestructuradas complementadas con notas y diarios de campo. Los datos fueron analizados mediante el análisis de contenido temático propuesto por Minayo. Resultados: La atención primaria, a través de la atención domiciliaria, fue la principal responsable del seguimiento posterior al alta de los participantes. Del material empírico, surgieron las categorías "sufrimiento emocional y sus repercusiones en la recuperación funcional" y "la pérdida del rol familiar y los conflictos con los cuidadores". Discusión y conclusiones: La recuperación funcional de pacientes con discapacidades funcionales después de pasar por cuidados intensivos puede ser compleja y requiere, además de rehabilitación física, monitoreo psicoemocional adecuado, aclaración de los recuerdos de hospitalización y apoyo profesional a la familia. Se sugiere que la atención primaria reciba capacitación sobre la complejidad de estos pacientes y la creación de estrategias que lo acerquen a la atención hospitalaria, lo que permite una atención compartida y continua.

Persistence of patient and family experiences of critical illness

OBJECTIVE

To investigate: (1) patient and family experiences with healthcare and the intensive care unit (ICU); (2) experiences during their critical illness; (3) communication and decision making during critical illness; (4) feelings about the ICU experience; (5) impact of the critical illness on their lives; and (6) concerns about their future after the ICU.

DESIGN

Four semistructured focus group interviews with former ICU patients and family members.

SETTINGS

Multicultural community group and local hospitals containing medical/surgical ICUs.

PARTICIPANTS

Patients and family who experienced a critical illness within the previous 10 years.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Four separate focus groups each lasting a maximum of 150 min and consisting of a total of 21 participants were held. Focus groups were conducted using a semistructured script including six topics relating to the experience of critical illness that facilitated deduction and the sorting of data by thematic analysis into five predominant themes. The five main themes that emerged from the data were: (1) personalised stories of the critical illness; (2) communication and shared decision making, (3) adjustment to life after critical illness, (4) trust towards clinical team and relevance of cultural beliefs and (5) end-of-life decision making. Across themes, we observed a misalignment between the medical system and patient and family values and priorities.

CONCLUSIONS

The experience of critical illness of a diverse group of patients and families can remain vivid for years after ICU discharge. The identified themes reflect the strength of memory of such pivotal experiences and the importance of a narrative around those experiences. Clinicians need to be aware of the lasting effects of critical illness has on patients and families.

Avaliação psicológica de pacientes após a alta da unidade de terapia intensiva

A maioria dos pacientes sobrevive ao episódio de doença crítica, contudo, muitos deles podem desenvolver alterações psicológicas após a alta desta unidade. Dada a natureza dos cuidados intensivos e as condições clínicas da maioria dos pacientes esta pesquisa tem como objetivo descrever os resultados da avaliação psicológica de pacientes três meses após a alta dos cuidados críticos. Foram avaliados 160 pacientes, no entanto, devido ao comprometimento neurológico apenas 137 conseguiram responder à avaliação psicológica. Os instrumentos utilizados foram: Planilha para coleta de dados do prontuário, instrumento de avaliação de memórias de UTI, Impact of Event Scale-Revised (IES-R) e Escala Hospitalar de Ansiedade e Depressão (HADS). Os resultados revelaram que a identificação precoce das complicações inerentes ao tratamento crítico poderá trazer benefícios para a prevenção de alterações emocionais/físicas crônicas subsequentes.

[Psychological care in German intensive care units : Results of a survey among the members of the German Interdisciplinary Association for Intensive Care and Emergency Medicine]

BACKGROUND

Psychological care should be provided in intensive care units (ICUs) because of the proven mental symptoms of patients and relatives. Even physicians and nurses can benefit from a corresponding care structure. Knowledge is lacking whether and how psychological care for patients and relatives as well as support for staff in German ICUs is implemented. For this reason, a survey was conducted among the members of the German Interdisciplinary Association for Intensive Care and Emergency Medicine (DIVI) to gain an overview of the current structures and the need for psychological support.

METHODS

The members of DIVI were invited to participate in a web-based survey. A total of 226 physicians and nurses took part in the survey. Analysis included statistics and group comparisons with Χ² methods.

RESULTS

In all care areas, psychological care of patients, relatives, and support for staff, respondents indicated a significant undersupply and expressed the need for improved care. A model which provides consular or team-integrated support based on the level of care is conceivable.

DISCUSSION

The current state of psychological care in German ICUs does not cover the existing need. Consequently the development of concepts and the beginning of discussions on how appropriate psychological care can be implemented in the future is necessary.

Protocol for a prospective, observational cohort study of awareness in mechanically ventilated patients admitted from the emergency department: the ED-AWARENESS study

INTRODUCTION

Awareness with paralysis is a complication with potentially devastating psychological consequences for mechanically ventilated patients. While rigorous investigation into awareness has occurred for operating room patients, little attention has been paid outside of this domain. Mechanically ventilated patients in the emergency department (ED) have been historically managed in a way that predisposes them to awareness events: high incidence of neuromuscular blockade use, underdosing of analgesia and sedation, delayed administration of analgesia and sedation after intubation, and a lack of monitoring of sedation targets and depth. These practice patterns are discordant to recommendations for reducing the incidence of awareness, suggesting there is significant rationale to examine awareness in the ED population.

METHODS AND ANALYSIS

This is a single centre, prospective cohort study examining the incidence of awareness in mechanically ventilated ED patients. A cohort of 383 mechanically ventilated ED patients will be included. The primary outcome is awareness with paralysis. Qualitative reports of all awareness events will be provided. Recognising the potential problem with conventional multivariable analysis arising from a small number of events (expected less than 10-phenomenon of separation), Firth penalised method, exact logistic regression model or penalised maximum likelihood estimation shrinkage (Ridge, LASSO) will be used to assess for predictors of awareness.

ETHICS AND DISSEMINATION

Approval of the study by the Human Research Protection Office has been obtained. This work will be disseminated by publication of peer-reviewed manuscripts, presentation in abstract form at scientific meetings and data sharing with other investigators through academically established means.

Early Interventions for the Prevention of Posttraumatic Stress Symptoms in Survivors of Critical Illness: A Qualitative Systematic Review

OBJECTIVES

Posttraumatic stress disorder among survivors of critical illness is of public health importance, as it is common and reduces patient quality of life. The objective of this systematic review was to collate the world's literature on interventions aimed at preventing posttraumatic stress disorder among survivors of critical illness.

DATA SOURCES

We performed a search of CENTRAL, MEDLINE, EMBASE, CINAHL, and clinical trials registry platforms, with no restriction to language using a comprehensive strategy.

STUDY SELECTION

Study inclusion criteria were as follows: 1) adult human subjects, 2) patients treated in an ICU setting, 3) intervention arm aimed at reducing posttraumatic stress disorder symptoms, 4) use of a control arm, and 5) an outcome measure assessing development of acute stress or posttraumatic stress disorder symptoms.

DATA EXTRACTION

We performed a qualitative analysis to collate and summarize effects of identified interventions according to the recommended methodology from the Cochrane Handbook.

DATA SYNTHESIS

Seventeen studies met all inclusion and no exclusion criteria. There was heterogeneity in interventions and outcome measures used. All studies had some concern for risk of bias as per the Cochrane tool for assessing risk of bias. In eight of 12 studies (67%) testing early interventions (i.e., initiated in the ICU course) and one of five studies (20%) testing delayed interventions following ICU discharge, posttraumatic stress disorder symptoms were decreased among the intervention group compared with controls.

CONCLUSIONS

Despite a paucity of high-quality clinical investigations, the preponderance of evidence to date suggests that 1) posttraumatic stress disorder among survivors of critical illness may be preventable and 2) early interventions may be the most effective.

The relationship between stressors and intensive care unit experiences

BACKGROUND

Patients in intensive care units (ICUs) face many physical and psychological stressors because of the environment of these units and their own critical conditions and experience stress in various degrees. Each stressor may affect patients' experiences in ICUs differently.

AIM AND OBJECTIVES

This study aimed to examine the relationship between stressors and patients' experiences in an ICU.

METHODS

This descriptive, cross-sectional study was conducted between September 2014 and June 2015 in a university hospital and included 116 patients who were admitted to the general ICU for at least 24 hours. Data were collected using the Intensive Care Experience Scale and a questionnaire that included questions about socio-demographic and disease-related characteristics of patients and their stressors.

RESULTS

The mean age of the patients was 57.81 ± 13.81 years, and the mean duration of ICU stay was 2.28 ± 3.88 days. There was a moderate positive relation between the stressors noise (r = .534; P < .01), thirst (r = .438; P < .01), loneliness (r = .410; P < .01), and pain (r = .404; P < .01) and the subscale frightening experiences. However, there was a moderate, negative relation between the stressors inability to speak (r = -.444; P < .01), surrounding speeches (r = -.458; P < .01), equipment noise (r = -.490; P < .01), and physical exercise (r = -.546; P < .01) and the subscale satisfaction with care.

CONCLUSIONS

The patients associated stressors with satisfaction and frightening experiences in the early period of their discharge from the ICU. As stressors increases, so do frightening experiences, and satisfaction with care is affected negatively.

RELEVANCE TO CLINICAL PRACTICE

Currently, stressors to which patients discharged from ICU are exposed during their admission to wards are not evaluated in practice. This study is important in that it can help health professionals be aware of effects of stressors on patients in the early period of their discharge.

Post-traumatic stress disorder (PTSD) related symptoms following an experience of delirium

AIM

To evaluate the prevalence of symptoms of PTSD and its correlates after 2 weeks of recovery, among patients, who developed delirium.

METHODOLOGY

A prospective study designed was followed, in which subjects diagnosed with delirium were evaluated 2 weeks after resolution of symptoms of delirium, for PTSD symptoms by using Impact of Events Scale-Revised version (IES-R).

RESULTS

59 patients were evaluated for PTSD 2 weeks after resolution of delirium and the total mean IES-R score was 27.81 (SD-11.41). Based on the IES-cut-off scores of the scale, 30.5% of the patients (n = 18) were considered to have substantial symptoms of PTSD, 22% (n = 13) had probable symptoms of PTSD and 15.3% were considered to have partial symptoms of PTSD after resolution of delirium. None of the demographic or clinical factors were associated with development of PTSD. Those with PTSD symptoms had significantly higher prevalence of fluctuation of symptoms, while experiencing delirium and had significantly higher mean scores for the items of motor agitation, attentional deficits, higher total severity score on the Delirium Rating Scale-revised-98 version (DRS-R98) and higher DRS-R-98 total score. Higher severity of delirium as indicated by the total DRS-R98 score and the total DRS-R98 severity score were associated with higher severity of PTSD symptoms. The IES-R total score did not have any significant correlation with duration of illness, duration of delirium or Charlson Co-morbidity index.

CONCLUSIONS

This study suggests that about one-third of patients who develop delirium go on to develop symptoms of PTSD, after recovery from delirium. Development of PTSD symptoms is associated with severity of delirium. Hence, it is important to treat the delirium adequately and provide psychological support to the patients who develop delirium, after recovery from delirium.

A nurse-led, preventive, psychological intervention to reduce PTSD symptom severity in critically ill patients: the POPPI feasibility study and cluster RCT

Background

High numbers of patients experience severe acute stress in critical care units. Acute stress has been linked to post-critical care psychological morbidity, including post-traumatic stress disorder (PTSD). Previously, a preventive, complex psychological intervention [Psychological Outcomes following a nurse-led Preventative Psychological Intervention for critically ill patients (POPPI)] was developed by this research team, to be led by nurses, to reduce the development of PTSD symptom severity at 6 months.

Objectives

The objectives were to (1) standardise and refine the POPPI intervention, and, if feasible, (2) evaluate it in a cluster randomised clinical trial (RCT).

Design

Two designs were used – (1) two feasibility studies to test the delivery and acceptability (to patients and staff) of the intervention, education package and support tools, and to test the trial procedures (i.e. recruitment and retention), and (2) a multicentre, parallel-group, cluster RCT with a baseline period and staggered roll-out of the intervention.

Setting

This study was set in NHS adult, general critical care units.

Participants

The participants were adult patients who were > 48 hours in a critical care unit, receiving level 3 care and able to consent.

Interventions

The intervention comprised three elements – (1) creating a therapeutic environment in critical care, (2) three stress support sessions for patients identified as acutely stressed and (3) a relaxation and recovery programme for patients identified as acutely stressed.

Main outcome measures

Primary outcome – patient-reported symptom severity using the PTSD Symptom Scale – Self Report (PSS-SR) questionnaire (to measure clinical effectiveness) and incremental costs, quality-adjusted life-years (QALYs) and net monetary benefit at 6 months (to measure cost-effectiveness). Secondary outcomes – days alive and free from sedation to day 30; duration of critical care unit stay; PSS-SR score of > 18 points; depression, anxiety and health-related quality of life at 6 months; and lifetime cost-effectiveness.

Results

(1) A total of 127 participants were recruited to the intervention feasibility study from two sites and 86 were recruited to the RCT procedures feasibility study from another two sites. The education package, support tools and intervention were refined. (2) A total of 24 sites were randomised to the intervention or control arms. A total of 1458 participants were recruited. Twelve sites delivered the intervention during the intervention period: > 80% of patients received two or more stress support sessions and all 12 sites achieved the target of > 80% of clinical staff completing the POPPI online training. There was, however, variation in delivery across sites. There was little difference between baseline and intervention periods in the development of PTSD symptom severity (measured by mean PSS-SR score) at 6 months for surviving patients in either the intervention or the control group: treatment effect estimate −0.03, 95% confidence interval (CI) −2.58 to 2.52; p = 0.98. On average, the intervention decreased costs and slightly improved QALYs, leading to a positive incremental net benefit at 6 months (£835, 95% CI −£4322 to £5992), but with considerable statistical uncertainty surrounding these results. There were no significant differences between the groups in any of the secondary outcomes or in the prespecified subgroup analyses.

Limitations

There was a risk of bias because different consent processes were used and as a result of the lack of blinding, which was mitigated as far as possible within the study design. The intervention started later than anticipated. Patients were not routinely monitored for delirium.

Conclusions

Among level 3 patients who stayed > 48 hours in critical care, the delivery of a preventive, complex psychological intervention, led by nurses, did not reduce the development of PTSD symptom severity at 6 months, when compared with usual care.

Future work

Prior to development and evaluation of subsequent psychological interventions, there is much to learn from post hoc analyses of the cluster RCT rich quantitative and qualitative data.

Prevalence of post-traumatic stress disorder symptoms in adult critical care survivors: a systematic review and meta-analysis

Background

As more patients are surviving intensive care, mental health concerns in survivors have become a research priority. Among these, post-traumatic stress disorder (PTSD) can have an important impact on the quality of life of critical care survivors. However, data on its burden are conflicting. Therefore, this systematic review and meta-analysis aimed to evaluate the prevalence of PTSD symptoms in adult critical care patients after intensive care unit (ICU) discharge.

Methods

We searched MEDLINE, EMBASE, LILACS, Web of Science, PsycNET, and Scopus databases from inception to September 2018. We included observational studies assessing the prevalence of PTSD symptoms in adult critical care survivors. Two reviewers independently screened studies and extracted data. Studies were meta-analyzed using a random-effects model to estimate PTSD symptom prevalence at different time points, also estimating confidence and prediction intervals. Subgroup and meta-regression analyses were performed to explore heterogeneity. Risk of bias was assessed using the Joanna Briggs Institute tool and the GRADE approach.

Results

Of 13,267 studies retrieved, 48 were included in this review. Overall prevalence of PTSD symptoms was 19.83% (95% confidence interval [CI], 16.72–23.13; I² = 90%, low quality of evidence). Prevalence varied widely across studies, with a wide range of expected prevalence (from 3.70 to 43.73% in 95% of settings). Point prevalence estimates were 15.93% (95% CI, 11.15–21.35; I² = 90%; 17 studies), 16.80% (95% CI, 13.74–20.09; I² = 66%; 13 studies), 18.96% (95% CI, 14.28–24.12; I² = 92%; 13 studies), and 20.21% (95% CI, 13.79–27.44; I² = 58%; 7 studies) at 3, 6, 12, and > 12 months after discharge, respectively.

Conclusion

PTSD symptoms may affect 1 in every 5 adult critical care survivors, with a high expected prevalence 12 months after discharge. ICU survivors should be screened for PTSD symptoms and cared for accordingly, given the potential negative impact of PTSD on quality of life. In addition, action should be taken to further explore the causal relationship between ICU stay and PTSD, as well as to propose early measures to prevent PTSD in this population.

Psychocognitive sequelae of critical illness and correlation with 3 months follow up

PURPOSE

Over a third of critical illness survivors manifest significant psychocognitive impairments following discharge from the intensive care unit (ICU). It is not known which patient populations are at highest risk or if assessment at ICU discharge can guide outpatient treatment prioritization.

MATERIALS AND METHODS

Prospective single center study in an academic medical center encompassing six types of ICUs assessed prevalence of psychocognitive morbidity based on ICU type and associations between initial and 3 month follow-up evaluation. Adult patients with >48 h ICU stays completed the Hospital Anxiety and Depression Scale (HADS), Impact of Events Scale-Revised (IES-R), and Montreal Cognitive Assessment-Blind (MoCA-blind).

RESULTS

Of 299 patients who underwent initial assessment, 174 (58%) completed follow-up. Length of stay, MoCA-Blind, HADS-A/D and IES-R scores were similar across ICUs. Most commonly observed impairment in-hospital was cognitive (58%) followed by anxiety (45%), acute stress (39%) and depression (37%). There were significant correlations between in-hospital and follow-up psychocognitive outcomes.

CONCLUSIONS

There was no significant difference in impairment by ICU type. Significant correlation between the initial assessment and follow-up scores suggests that early screening of high risk patients may identify those at greatest risk of sustained morbidity and facilitate timely intervention.

Healthcare provider compassion is associated with lower PTSD symptoms among patients with life-threatening medical emergencies: a prospective cohort study

PURPOSE

We tested the hypothesis that, during a life-threatening medical emergency, patient perception of healthcare provider (HCP) compassion is associated with the subsequent development of post-traumatic stress disorder (PTSD) symptoms.

METHODS

Prospective cohort study in the emergency department (ED) of an urban academic medical center. We included adult patients presenting with a life-threatening medical emergency, defined as respiratory or cardiovascular instability requiring a potentially life-sustaining intervention in the ED. We measured patient perception of HCP compassion in the ED using the Consultation and Relational Empathy (CARE) measure, a validated 40-point scale. Blinded to clinical outcomes (including the CARE measure), we assessed PTSD symptoms 1 month post-discharge using the PTSD Checklist for the Diagnostic and Statistical Manual of Mental Disorders-5.

RESULTS

Of the 99/113 (88%) patients who completed follow-up, 25% (95% CI 17-35%) had PTSD symptoms at 1 month. In a multivariable model adjusting for potential confounders (e.g. severity of illness score in ED, need for intensive care unit admission, ED overcrowding, and family member emotional support in the ED), patient perception of greater HCP compassion in the ED was independently associated with lower PTSD symptoms at 1 month [odds ratio 0.93 (95% CI 0.89-0.98)]. A one-point increase in the CARE measure was associated with a 7% decrease in the odds of developing PTSD symptoms.

CONCLUSIONS

PTSD symptoms are common among ED patients with life-threatening medical emergencies. Patient perception of greater HCP compassion during the emergency is independently associated with lower risk of developing PTSD symptoms.

Relationship of symptoms associated with ICU-survivorship: An integrative literature review

BACKGROUND

The number of adults who survive a critical illness involving admission to an intensive care unit is increasing. These survivors have an increased risk of developing impairments in cognition, physical function and psychological health.

OBJECTIVE

This integrative literature review examined the literature for studies exploring the relationships among two or more of the variables of interest, i.e. cognitive, physical, and psychological symptoms (depressive, anxiety, or posttraumatic stress) in intensive care unit survivors post-hospital discharge.

METHODS

A literature search was conducted using PubMed, CINHAL and PsycINFO databases.

FINDINGS

While all 13 studies included in the review explored some aspect of a relationship among the variables of interest, none explored associations among all three variables. Five studies explored physical function and psychological symptoms, four studies explored cognitive impairment and psychological symptoms and five studies explored the association among different psychological symptoms. Inconsistencies were found in the study designs, follow-up time frames, patient populations and measures used.

CONCLUSIONS

Further research using well-designed methodologies and standardized instruments is warranted. Gaining a better understanding of the relationships among these impairments has the potential to contribute to the development of screening guidelines, preventative strategies, and treatments.

Work-related burn injuries and claims for post-traumatic stress disorder in Korea

OBJECTIVE

The objective of this study is to broaden our understanding of psychiatric disorders due to work-related burn injury compensated by the Industrial Accident Compensation Insurance operated by the Korea Workers' Compensation and Welfare Service (KCOMWEL).

METHODS

Using the KCOMWEL electronic database, we collected data on psychiatric disorders due to work-related burn injury based on workers' compensation records from 2005 to 2014 and analyzed the characteristics of the claims.

RESULTS

The average number of claims per year for post-traumatic stress disorder was 67 and the approval rate from 2005 to 2014 was 53.6%. Regarding occupation, 63 workers were elementary workers involved in the performance of simple and routine tasks which may require the use of hand-held tools and considerable physical effort and 59 were electrical and electronic equipment fitters and repairers. Acute stress disorder, nonorganic insomnia, and sexual dysfunction were the most commonly approved psychiatric disorders associated with work-related burn injury, followed by mixed anxiety-depressive disorder.

CONCLUSIONS

We analyzed the characteristics of the psychiatric disorders due to work-related burn injury for which compensation was received from 2005 to 2014 according to the approved results. To gain a long-term understanding of the management of workers' compensation status for psychiatric disorders due to work-related burn injuries, we should gather accurate information on the risk factors involved in order to achieve the needed systematic improvements.

Long-term follow-up for Psychological stRess in Intensive CarE (PRICE) survivors: study protocol for a multicentre, prospective observational cohort study in Australian intensive care units

INTRODUCTION

There are little published data on the long-term psychological outcomes in intensive care unit (ICU) survivors and their family members in Australian ICUs. In addition, there is scant literature evaluating the effects of psychological morbidity in intensive care survivors on their family members. The aims of this study are to describe and compare the long-term psychological outcomes of intubated and non-intubated ICU survivors and their family members in an Australian ICU setting.

METHODS AND ANALYSIS

This will be a prospective observational cohort study across four ICUs in Australia. The study aims to recruit 150 (75 intubated and 75 non-intubated) adult ICU survivors and 150 family members of the survivors from 2015 to 2018. Long-term psychological outcomes and effects on health-related quality of life (HRQoL) will be evaluated at 3 and 12 months follow-up using validated and published screening tools. The primary objective is to compare the prevalence of affective symptoms in intubated and non-intubated survivors of intensive care and their families and its effects on HRQoL. The secondary objective is to explore dyadic relations of psychological outcomes in patients and their family members.

ETHICS AND DISSEMINATION

The study has been approved by the relevant human research ethics committees (HREC) of Australian Capital Territory (ACT) Health (ETH.11.14.315), New South Wales (HREC/16/HNE/64), South Australia (HREC/15/RAH/346). The results of this study will be published in a peer-reviewed medical journal and presented to the local intensive care community and other stakeholders.

Need for psychological support in intensive care : A survey among members of the German Society of Medical Intensive Care and Emergency Medicine

A high incidence of care-relevant psychological problems in critical care medicine has been reported among patients, their families and professional care givers. International guidelines give appropriate recommendations for such care. What is unclear, however, is just how the care and support are provided in day-to-day practice and, in particular, which service providers are responsible for this support. The present care situation was studied in a web-based survey (38% response rate) among all members of the German Society of Medical Intensive Care and Emergency Medicine (DGIIN). Most respondents reported a moderate to substantial need for psychological support of patients in intensive care and a substantial to very substantial need in the case of their family members. The need for support in the case of staff showed a relatively broad scatter in the assessment. Providers of care are mainly the members of the intensive care team themselves, while clinical pastoral counsellors in particular are also involved and, to a lesser extent, counselling or liaison services specializing in psychotherapy.

The Lifetime Effects of Injury: Postintensive Care Syndrome and Posttraumatic Stress Disorder

Postintensive care syndrome (PICS) is a heterogeneous syndrome marked by physical, cognitive, and mental health impairments experienced by critical care survivors. It is a syndrome that bears significant human and health care costs. Additional research is needed to identify risk factors and diagnostic, preventative, and treatment strategies for PICS. Trauma intensive care unit patients are particularly vulnerable to posttraumatic stress disorder, which shares some of the adverse long-term consequences of PICS and also requires additional research into effective preventative and management strategies.

Acute stress and subsequent health outcomes: A systematic review

OBJECTIVE

To systematically review the relationship between acute posttraumatic stress symptoms (<1 month) and subsequent physical and mental health outcomes other than posttraumatic stress disorder (PTSD).

METHODS

A systematic search of electronic databases (PubMed, PsycINFO, CINAHL, and Web of Science) was conducted to identify longitudinal studies examining the link between acute posttraumatic stress and physical and mental health. Inclusion criteria required assessment of acute posttraumatic stress (<1 month post-event) and at least one follow-up assessment of a physical or mental health outcome (not PTSD).

RESULTS

1,051 articles were screened; 22 met inclusion criteria. Fourteen studies examined physical health outcomes and 12 examined non-PTSD mental health outcomes. Early psychological responses to trauma were associated with a variety of short- (<1 year) and long- (≥1 year) term physical and mental health outcomes. Physical health outcomes included poor general physical health, increased pain and disability, lower quality of life, and higher risk of all-cause mortality. Significant psychological outcomes included more cumulative psychiatric disorders, depression, and anxiety. Significant psychosocial outcomes included increased family conflict.

CONCLUSIONS

Methodologically rigorous longitudinal studies support the utility of measuring acute psychological responses to traumatic events as they may be an important marker of preventable trauma-related morbidity and mortality that warrants long-term monitoring and/or early intervention.
