Post-intensive care syndrome: impact, prevention, and management

Comparing virtual reality with traditional methods in cognitive rehabilitation in PICS syndrome

INTRODUCTION

Post Intensive Care Unit Syndrome (PICS) manifests deficits in physical, cognitive, and mental functions following ICU hospitalization and complicates the recovery process.

AIM

The clinical trial aimed to assess the impact of neuropsychological rehabilitation on cognitive deficits arising from ICU hospitalization. Additionally, it sought to compare the effectiveness of VR-based rehabilitation with traditional methods and investigate the safety and feasibility of VR intervention.

METHODOLOGY

Thirty participants were divided into experimental and control groups. The experimental group underwent cognitive training using VR, while the control group utilized traditional methods. Neuropsychological assessments (Addenbrooke's Cognitive Examination-Revised (ACE-R), Frontal Assessment Battery (FAB), and Geriatric Depression Scale (GDS)) were conducted before and after a 12-session intervention (three times a week for four weeks).

RESULTS

Regardless of the intervention type, participants exhibited statistically significant improvements in general cognitive function (p = 0.02), attention (p = 0.016), visuospatial (p = 0.03), and executive functions (p = 0.011). The experimental group showed greater improvement in visuospatial function (p = 0.011), while the control group demonstrated enhanced language fluency (p = 0.019). Correlations between cognitive functions were observed in baseline measures and their differences. VR was found to be a safe, suitable, and enjoyable rehabilitation method, as indicated by Suitability Evaluation Questionnaire (SEQ) scores, with a mean of 60.7 (SD = 5.5).

DISCUSSION

These preliminary data suggest that VR can be effective in the rehabilitation of cognitive functions in ICU survivors with PICS, especially in visuospatial abilities. Large-scale longitudinal clinical trials involving diverse patient groups are needed to explore the long-term impact of VR interventions on cognitive functions.

Post-infection symptoms up to 24 months after COVID-19: a matched cohort study in Berlin, Germany

Introduction

Long-term health consequences after mild COVID-19 are not well described. Our aim was to estimate their prevalence and describe the time course of signs and symptoms for a period of up to 24 months after SARS-CoV-2 infection.

Methods

We conducted a cohort study matched for age, sex, and test week among individuals who had attended the public COVID-19 test center at Charité-Universitätsmedizin Berlin, Germany. In early 2022, 576 former COVID-19 patients (>95% non-hospitalized) and 302 uninfected individuals responded to a questionnaire on retrospective monthly symptoms since the test date up to 24 months ago.

Results

Symptoms compatible with long COVID were present in 42.9% (247/576) of former COVID-19 patients, compared with 21.2% (64/302) in the uninfected group. In former patients, unadjusted odds ratios (OR) were highest for disturbed taste/smell (OR 9.1 [95% CI: 4.0-21.1]), memory difficulties (OR 5.1 [95% CI: 2.9-8.9]), and shortness of breath at rest (OR 4.5 [95% CI: 1.9-10.6]). In most former COVID-19 patients, symptoms occurred in one coherent period and resolved after a median of 6.5 months, while taste/smell disturbance and neurological/cognitive symptoms showed longer times until recovery. Factors associated with long COVID-compatible symptoms included hospitalization, symptomatic COVID-19 infection, low household income and female sex.

Conclusion

Post-infection symptoms in mild COVID-19 patients mostly persist for about half a year, but sometimes longer. Among uninfected individuals who never experienced COVID-19, 21.2% also reported long COVID-compatible symptoms. The current long COVID definition might require revision to prevent misclassification and over-reporting, and to improve diagnosis and prevalence estimates.

Music-based interventions and theoretical mechanisms in post-ICU survivors: A critical narrative synthesis

BACKGROUND

Hospitalization in the ICU can have long-term physiological and psychological impacts, affecting functional recovery and quality of life of post-ICU patients. Despite systematic reviews showing the impact of music interventions on physiological and psychological outcomes in ICU patients, their applicability and effectiveness in the post-ICU context remain unclear.

AIM

This review aimed to summarize: a) the types and characteristics of music/sound of interventions used in the rehabilitation of ICU patients, b) evidence on the feasibility, safety and acceptability of sound and music interventions for post ICU survivors, c) the types of post-ICU outcomes explored and the effects of sound and music interventions on any type of outcome in post-ICU survivors, and d) potential mechanisms or theoretical frameworks underlying the effects of sound and music interventions.

METHOD

We combined current systematic review search methods with a critical narrative approach to synthesize a diverse body of evidence.

RESULTS

Results showed that music interventions positively affect the psychological well-being and health outcomes of post-ICU patients. Outcomes included improvements in stress, anxiety, mood, movement, sleep, and pain, despite differences in patient populations and intervention design. No safety concerns were reported. The identified theoretical frameworks described physiological, neurobiological and/or psycho-social pathways as key mediators, however, these mechanisms are not completely understood.

CONCLUSION

Research evidence supports the positive effects of music interventions in post-ICU patients. Further experimental studies are required, especially in adult post-ICU populations to elucidate the characteristics, components, feasibility, and long-term effects of sound/music interventions.

IMPLICATION TO PRACTICE

1. Music interventions help in post-ICU patients' recovery benefitting stress, anxiety, PTSD, mood, movement, sleep, and pain. 2. Integrating theoretical frameworks into music interventions can expand outcome measures to include physiological markers alongside psychological ones, improving quality of life. 3. Further rigorous interventional studies are required to identify the effectiveness of sound and music interventions in post-ICU patients.

Mobile Applications for Longitudinal Data Collection: Web-based Survey Study of Former Intensive Care Patients

PURPOSE

Mobile health plays an important role in providing individualized information about the health status of patients. Limited information exists on intensive care unit (ICU) patients with the risk of suffering from the post-intensive care syndrome (PICS), summarizing long-term physical, mental and cognitive impairment. This web-based survey study aims to identify specific needs of former ICU patients for utilizing a newly developed, so called Post-Intensive Care Outcome Surveillance (PICOS) app to collect relevant PICS-related parameters.

METHODS

A prototype app was developed following interaction principles for interactive systems of usability engineering. Patients from four different German hospitals were asked about demographics, interaction with technology and their perception of the prototype regarding hedonic motivation, perceived ease of use and performance expectancy.

RESULTS

123 patients participated in the survey; the majority owned and used smartphones. Nearly half of respondents would seek help from family members or caregivers using the app. There was a difference in affinity for technology for participants who own a smartphone and those who do not, t(116) = - 0.97, p = .335, and no significant difference in affinity for technology whether the participants would like support when using the app or not, t(97) = 1.81, p = .073. The average hedonic motivation for using the app was M = 4.44 (SD = 1.304).

CONCLUSION

This app prototype was perceived as both beneficial and easy to use, indicating its success among former ICU patients. Due to aging and ongoing health impairments, every second patient would need assistance with the initial use of the app.

IMPACT-ICU feasibility study: pragmatic mixed-methods randomised controlled trial of a follow-up care intervention for survivors of critical illness and caregivers

INTRODUCTION

Survivors of critical illness and their caregivers are at risk for long-term cognitive, physical and psychiatric impairments known as post-intensive care syndrome (PICS) and PICS-family, respectively. This study will assess the feasibility of a randomised controlled trial (RCT) evaluating an intensive care unit (ICU) follow-up care bundle versus standard-of-care for ICU patients and their caregivers.

METHODS AND ANALYSIS

This is a single-centre feasibility study. Survivors of critical illness will be eligible if: age ≥18 years, life expectancy ≥6 months and high risk for PICS. We define high risk as ICU stay ≥4 days or involving 1+ of mechanical ventilation, tracheostomy, delirium or lack of access to a primary care physician (PCP). 20 ICU survivor-primary caregiver dyads will be enrolled (n=10 dyads per group) and randomised 1:1 to the intervention versus control group. The intervention will be: (1) diaries to journal patient experiences, (2) information packages on expectations post-discharge and (3) specialised follow-up care at 1 and 3 months post-discharge. The control group will receive standard of care in the ICU and follow-up with their PCP. The primary outcome is feasibility, defined as: (1) consent rate >80%, (2) enrolment rate of 4 participants/month, (3) follow-up rate>70% and (4) data capture rate >80%. Our secondary objective is to explore the perspectives of survivors of critical illness and their families about the intervention and their participation in the study. Tertiary outcomes will be a battery of cognitive, physical functioning and psychiatric outcomes.

IMPLICATIONS

Survivorship from critical illness extends beyond surviving an ICU stay. This project will lay the foundation for performing a large, multicentre pragmatic RCT with survivors of critical illness and their caregivers, paving the way for improved long-term healthcare.

ETHICS AND DISSEMINATION

This study has received approval (6039808) from the Queen's University Health Sciences/Affiliated Teaching Hospitals Research Ethics Board. Results will be presented at critical care conferences. A lay summary co-designed with ICU survivor participants will be provided to patients.

Video Game Therapy in a Neurosciences Critical Care Unit: A Pilot Study

BACKGROUND

Therapeutic activity after stroke is a component of early recovery strategies. Interactive video games have been shown to be safe as an adjunct rehabilitation therapy in the medical intensive care setting, but patients with neurologic disease were often excluded from those protocols.

OBJECTIVES

To evaluate the feasibility and safety of individualized interactive video game therapy in critically ill neurologic patients.

METHODS

Adults admitted to the neurosciences critical care unit during the observation period were eligible for inclusion. Wii sports games with the potential to target common neurologic deficits were categorized by our interprofessional team. We collected information regarding the number of sessions attempted, time for setup, indications of use, patient/staff experience, and predefined safety events.

RESULTS

Twelve sessions were completed in 9 patients, mean (SD) age 48.6 (18.1) years, and sessions were led by nursing and therapy teams. Prescribed video game therapy sessions targeted the following recovery domains: coordination (70%), balance (50%), endurance (30%), cognition (30%), fine motor control (30%), neglect (20%), engagement in activity (10%), and vision (30%). On average, 4.7 minutes were spent for setup and 18.8 minutes were spent playing video games. No safety issues were identified. All patients indicated that they enjoyed participating in video game therapy.

CONCLUSIONS

In this pilot study, prescriptive interactive video game therapy in early rehabilitation was feasible and safe in the neurosciences critical care setting. Video game therapy may be a valuable complement to existing rehabilitation for critically ill neurologic patients and warrants validation in a larger patient sample.

Long-term prevalence of PTSD symptom in family members of severe COVID-19 patients: a serial follow-up study extending to 18 months after ICU discharge

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.

METHODS

This prospective study, conducted in a tertiary university hospital in Tokyo, enrolled family members of severe COVID-19 ICU patients (July 2020 to June 2022 with final follow-up ending in December 2023). The primary outcome was family member symptoms of PTSD at 6, 12 and 18 months after ICU discharge, measured by the Impact of Events Scale-Revised (presence of PTSD symptoms defined by score > 24). Secondary outcomes were family member symptoms of anxiety and depression, sleep disorders, and health-related quality of life (HRQOL) at the same timepoint.

RESULTS

Among 97 enrolled family members, 68 participated. At least one PTSD-related symptom was reported by 26% of family members, persisting over 18 months post-discharge (16% at 6 months, 23% at 12 months, and 25% at 18 months). A subgroup (15%) exhibited delayed-onset PTSD symptoms. Family members with PTSD-related symptoms reported lower HRQOL, especially in mental and social components.

CONCLUSIONS

The study underscores the importance of long-term support for family members post-ICU discharge, given the sustained prevalence of PTSD-related symptoms among family members of severe COVID-19 patients.

Updates on Post-Intensive Care Syndrome After Acute Respiratory Distress Syndrome: Epidemiology, Core Outcomes, Interventions, and Long-Term Follow-Up

Acute respiratory distress syndrome (ARDS) survivors often experience post-intensive care syndrome (PICS), is defined as new or worsened impairments in physical, cognitive and/or mental health status persisting beyond hospital discharge. These impairments negatively impact survivors' quality of life and their return to work or usual activities. Moreover, family members are also impacted as recognized by the term, PICS-Family (PICS-F). PICS poses an increased burden on the health care system and has a negative societal impact. There are ongoing efforts to understand risk factors for PICS-related impairments; design and evaluate interventions for specific impairments (including the use of an ARDS survivorship core outcome set); and refine and evaluate ICU recovery clinics to support and treat survivors and their families.

Long-term sequelae and management following obstetric sepsis

The long-term consequences of obstetric sepsis have been a growing area of concern requiring attention. This narrative review summarizes the existing literature on the long-term sequelae of sepsis, with a focus on the antepartum and postpartum periods. In this article, we discuss risk factors for and epidemiology of post-sepsis syndrome (PSS) and related long-term medical conditions. We include recommendations for screening for PSS and management strategies involving multidisciplinary teams. PSS and other long-term medical and psychological sequelae of sepsis impact individuals and their communities greatly, including the obstetric population. There is a need for improved identification, management, and coordination of care for long-term complications of sepsis. Gaps in the literature for future study include identifying specific needs of the obstetric population in the weeks, months, and years following a sepsis event.

Postintensive care syndrome: Development and psychometric validation of a knowledge test

INTRODUCTION

Postintensive care syndrome (PICS) is a combination of short-, medium- and long-term morbidities that occur in patients discharged from the Intensive care unit (ICU). ICU professionals have a crucial role in managing and understanding the PICS. This study aimed to develop the PICS Knowledge Test (PICS-KT), which measures ICU professionals' awareness and knowledge levels regarding PICS, and to determine its validity and reliability.

METHODS

The databases were searched in detail, scientific research related to PICS was analyzed, and the draft scale was created accordingly. A total of 117 doctors and nurses who had been working in the ICU for at least 6 months were included in the study. For the validity and reliability analysis of the test, content validity ratio, item difficulty index, item discrimination index values and Cronbach α were examined.

RESULTS

The Cronbach's α reliability coefficient for the 46-item PICS-KT is 0.93, indicating high reliability. Scores range from 0 to 46, with 32 or higher considered successful, suggesting adequate knowledge of PICS among ICU professionals. Scores of 14 or less indicate minimal knowledge. Those with scores between 14 and 32 possess some knowledge but need improvement. PICS-KT assesses knowledge in four main areas: general information, risk factors/causes, symptoms and findings and interventions. ICU professionals show high awareness of interventions for preventing and treating PICS, as indicated by a high mean score in the interventions subdimension.

CONCLUSION

The PICS-KT is crucial in assessing healthcare professionals' understanding of the various short-, medium- and long-term morbidities associated with PICS. The study ensures that the test is a robust and dependable instrument for evaluating ICU professionals' knowledge about PICS.

Association between inflammation and post-intensive care syndrome: a systematic review

Post-intensive care syndrome describes the physical, cognitive and emotional symptoms which persist following critical illness. At present there is limited understanding of the pathological mechanisms contributing to the development of post-intensive care syndrome. The aim of this systematic review was to synthesise current evidence exploring the association between inflammation and features of post-intensive care syndrome in survivors of critical illness. Relevant databases were systematically searched for studies of human participants exposed to critical illness. We sought studies that reported results for biomarkers with an identified role in the pathophysiology of inflammation obtained at any time-point in the patient journey and an outcome measure of any feature of post-intensive care syndrome at any point following hospital discharge. We included 32 studies, with 23 in the primary analysis and nine in a brain injury subgroup analysis. In the primary analysis, 47 different biomarkers were sampled and 44 different outcome measures were employed. Of the biomarkers which were sampled in five or more studies, interleukin-8, C-reactive protein and interleukin-10 most frequently showed associations with post-intensive care syndrome outcomes in 71%, 62% and 60% of studies, respectively. There was variability in terms of which biomarkers were sampled, time-points of sampling and outcome measures reported. Overall, there was mixed evidence of a potential association between an inflammatory process and long-term patient outcomes following critical illness. Further high-quality research is required to develop a longitudinal inflammatory profile of survivors of critical illness over the recovery period and evaluate the association with outcomes.

The effect of an improved ICU physical environment on outcomes and post-ICU recovery-a protocol

BACKGROUND

Intensive care medicine continues to improve, with advances in technology and care provision leading to improved patient survival. However, this has not been matched by similar advances in ICU bedspace design. Environmental factors including excessive noise, suboptimal lighting, and lack of natural lights and views can adversely impact staff wellbeing and short- and long-term patient outcomes. The personal, social, and economic costs associated with this are potentially large. The ICU of the Future project was conceived to address these issues. This is a mixed-method project, aiming to improve the ICU bedspace environment and assess impact on patient outcomes. Two innovative and adaptive ICU bedspaces capable of being individualised to patients' personal and changing needs were co-designed and implemented. The aim of this study is to evaluate the effect of an improved ICU bedspace environment on patient outcomes and operational impact.

METHODS

This is a prospective multi-component, mixed methods study including a randomised controlled trial. Over a 2-year study period, the two upgraded bedspaces will serve as intervention beds, while the remaining 25 bedspaces in the study ICU function as control beds. Study components encompass (1) an objective environmental assessment; (2) a qualitative investigation of the ICU environment and its impact from the perspective of patients, families, and staff; (3) sleep investigations; (4) circadian rhythm investigations; (5) delirium measurements; (6) assessment of medium-term patient outcomes; and (7) a health economic evaluation.

DISCUSSION

Despite growing evidence of the negative impact the ICU environment can have on patient recovery, this is an area of critical care medicine that is understudied and commonly not considered when ICUs are being designed. This study will provide new information on how an improved ICU environment impact holistic patient recovery and outcomes, potentially influencing ICU design worldwide.

An Evolutionary Concept Analysis of the "Fighter" in the Intensive Care Unit

The purpose of this article was to analyze the concept of "the fighter in the intensive care unit (ICU)" per the scientific literature and the impact this mentality has on care administered in the ICU. A literature review and a concept analysis based on Rodger's evolutionary method were performed to identify surrogate terms, antecedents, attributes, and consequences pertaining to the "fighter" in the ICU. Thirteen articles with a focus on "the fighter" were included in this analysis. There is a strong desire to remain optimistic and maintain high spirits as a coping mechanism in the face of extreme prognostic uncertainty. Themes that emerged from the literature were the need to find inner strength and persist in the face of adversity. The concept of "the fighter in the ICU" can serve as either adaptive or maladaptive coping, depending on the larger clinical picture. Patient experiences in the ICU are fraught with physical and psychological distress. How the patient and family unit cope during this anxiety-provoking time is based on the individual. Maintaining optimism and identifying as a fighter can be healthy ways to adapt to the circumstances. This concept analysis highlights the importance of holistic care and instilling hope particularly as patients may be nearing the end of life.

From the Intensive Care Unit to Recovery: Managing Post-intensive Care Syndrome in Critically Ill Patients

Post-intensive care syndrome (PICS) is the term used to describe the decline in the physical, cognitive, and/or mental condition of individuals who have been discharged from the intensive care unit (ICU). This complication could result in a significant reduction in quality of life, with some patients experiencing symptoms of prolonged weakness, depression, anxiety, and post-traumatic stress disorder (PTSD). Intensive care advancement over the years has resulted in an increase in ICU survival rates and a proportional increase in PICS, creating a need for more in-depth research into the prevention and management of the disease. Hence, this study aims to examine the present body of literature on PICS, encompassing its underlying physiological processes and elements that contribute to its development, methods for evaluating and diagnosing the condition, current treatment choices as well as potential new approaches, and the constraints in managing PICS and the necessity for further investigation. In this article, studies were compiled from several databases, including, but not limited to, Google Scholar, PubMed, and Cochrane Library. These studies were reviewed, and their data were used to highlight important aspects regarding the efficacy of current PICS screening tools, the optimization and limitations of both pharmacologic and non-pharmacologic treatment methods, and the feasibility and safety of emerging treatments and technologies. The major conclusions of this review were centered around the need for multidisciplinary management of PICS. From pharmacological management using analgesia to non-pharmacological management using early mobilization and exercise therapy, the effective treatment of PICS requires a multifaceted approach. Patient follow-up and its importance were touched upon, including strategies and policies to bolster proper follow-up, thereby increasing favorable outcomes. Lastly, the importance of family involvement and the increased need for research into this topic were highlighted.

Persistent inflammation, immunosuppression, and catabolism syndrome (PICS): a review of definitions, potential therapies, and research priorities

Persistent Inflammation, Immunosuppression, and Catabolism Syndrome (PICS) is a clinical endotype of chronic critical illness. PICS consists of a self-perpetuating cycle of ongoing organ dysfunction, inflammation, and catabolism resulting in sarcopenia, immunosuppression leading to recurrent infections, metabolic derangements, and changes in bone marrow function. There is heterogeneity regarding the definition of PICS. Currently, there are no licensed treatments specifically for PICS. However, findings can be extrapolated from studies in other conditions with similar features to repurpose drugs, and in animal models. Drugs that can restore immune homeostasis by stimulating lymphocyte production could have potential efficacy. Another treatment could be modifying myeloid-derived suppressor cell (MDSC) activation after day 14 when they are immunosuppressive. Drugs such as interleukin (IL)-1 and IL-6 receptor antagonists might reduce persistent inflammation, although they need to be given at specific time points to avoid adverse effects. Antioxidants could treat the oxidative stress caused by mitochondrial dysfunction in PICS. Possible anti-catabolic agents include testosterone, oxandrolone, IGF-1 (insulin-like growth factor-1), bortezomib, and MURF1 (muscle RING-finger protein-1) inhibitors. Nutritional support strategies that could slow PICS progression include ketogenic feeding and probiotics. The field would benefit from a consensus definition of PICS using biologically based cut-off values. Future research should focus on expanding knowledge on underlying pathophysiological mechanisms of PICS to identify and validate other potential endotypes of chronic critical illness and subsequent treatable traits. There is unlikely to be a universal treatment for PICS, and a multimodal, timely, and personalised therapeutic strategy will be needed to improve outcomes for this growing cohort of patients.

Right Ventricular Dysfunction on Transthoracic Echocardiography and Long-Term Mortality in the Critically Unwell: A Systematic Review and Meta-Analysis

OBJECTIVE

Right ventricular dysfunction (RVD) is common in the critically ill. To date studies exploring RVD sequelae have had heterogenous definitions and diagnostic methods, with limited follow-up. Additionally much literature has been pathology specific, limiting applicability to the general critically unwell patient.

METHOD AND STUDY DESIGN

We conducted a systematic review and meta-analysis to evaluate the impact of RVD diagnosed with transthoracic echocardiography (TTE) on long-term mortality in unselected critically unwell patients compared to those without RVD. A systematic search of EMBASE, Medline and Cochrane was performed from inception to March 2022. All RVD definitions using TTE were included. Patients were those admitted to a critical or intensive care unit, irrespective of disease processes. Long-term mortality was defined as all-cause mortality occurring at least 30 days after hospital admission. A priori subgroup analyses included disease specific and delayed mortality (death after hospital discharge/after the 30th day from hospital admission) in patients with RVD. A random effects model analysis was performed with the Dersimionian and Laird inverse variance method to generate effect estimates.

RESULTS

Of 5985 studies, 123 underwent full text review with 16 included (n = 3196). 1258 patients had RVD. 19 unique RVD criteria were identified. The odds ratio (OR) for long term mortality with RVD was 2.92 (95% CI 1.92-4.54, I2 76.4%) compared to no RVD. The direction and extent was similar for cardiac and COVID19 subgroups. Isolated RVD showed an increased risk of delayed mortality when compared to isolated left/biventricular dysfunction (OR 2.01, 95% CI 1.05-3.86, I2 46.8%).

CONCLUSION

RVD, irrespective of cause, is associated with increased long term mortality in the critically ill. Future studies should be aimed at understanding the pathophysiological mechanisms by which this occurs. Commonly used echocardiographic definitions of RVD show significant heterogeneity across studies, which contributes to uncertainty within this dataset.

Mental Health in Women

Mental health illness has been increasing worldwide. The prevalence of mental illness and is higher among females than among males. It is estimated that one in 5 women experience a common mental health disorder. This article highlights gender disparities in the risk, prevalence, and presentation of different mental health disorders. Nearly all survivors of critical illness experience 1 or more domains of the post-intensive care syndrome. We review different mental health disorders including anxiety disorders, mood disorders, psychotic disorders, and post-intensive care syndrome, and medications used to manage these disorders. Delirium in the intensive care unit can be misdiagnosed as a primary psychiatric disorder and is important to distinguish from each other. We also highlight the inadequacy of surveillance and recognition of mental health disorders in the intensive care unit, leading to missed opportunities to properly manage these important psychiatric conditions.

Development of a population-level prediction model for intensive care unit (ICU) survivorship and mortality in older adults: A population-based cohort study

Background and Aims

Given the growing utilization of critical care services by an aging population, development of population-level risk models which predict intensive care unit (ICU) survivorship and mortality may offer advantages for researchers and health systems. Our objective was to develop a risk model for ICU survivorship and mortality among community dwelling older adults.

Methods

This was a population-based cohort study of 48,127 patients who were 50 years and older with at least one primary care visit between January 1, 2017, and December 31, 2017. We used electronic health record (EHR) data to identify variables predictive of ICU survivorship.

Results

ICU admission and mortality within 2 years after index primary care visit date were used to divide patients into three groups of "alive without ICU admission", "ICU survivors," and "death." Multinomial logistic regression was used to identify EHR predictive variables for the three patient outcomes. Cross-validation by randomly splitting the data into derivation and validation data sets (60:40 split) was used to identify predictor variables and validate model performance using area under the receiver operating characteristics (AUC) curve. In our overall sample, 92.2% of patients were alive without ICU admission, 6.2% were admitted to the ICU at least once and survived, and 1.6% died. Greater deciles of age over 50 years, diagnoses of chronic obstructive pulmonary disorder or chronic heart failure, and laboratory abnormalities in alkaline phosphatase, hematocrit, and albumin contributed highest risk score weights for mortality. Risk scores derived from the model discriminated between patients that died versus remained alive without ICU admission (AUC = 0.858), and between ICU survivors versus alive without ICU admission (AUC = 0.765).

Conclusion

Our risk scores provide a feasible and scalable tool for researchers and health systems to identify patient cohorts at increased risk for ICU admission and survivorship. Further studies are needed to prospectively validate the risk scores in other patient populations.

Screening tools for post-intensive care syndrome and post-traumatic symptoms in intensive care unit survivors: A scoping review

BACKGROUND

Evidence suggests that intensive care unit (ICU) survivors often suffer long-term complications such as post-intensive care syndrome (PICS) and post-traumatic stress disorder (PTSD) from critical illness and ICU stay. PICS and PTSD affect both ICU survivors and their families, which overburdens the healthcare systems. Lack of evidence on the comparative psychometric properties of assessment tools is a major barrier in evidence-based screening for post-ICU symptomatology and health-related quality of life.

OBJECTIVES

We aimed to identify existing tools for screening PTSD and PICS in ICU survivors and their families and to examine evidence on the validity, reliability, sensitivity, and specificity of existing tools, as reflected in published peer-reviewed studies.

METHOD

A scoping review based on literature searches (CINAHL, MEDLINE, EMBASE, PsycINFO, Scopus, Health and Psychosocial Instruments, Dissertations and Theses Global, and Google Scholar) and predefined eligibility criteria was conducted according to current scoping review guidelines.

FINDINGS

We identified 44 studies reporting on the development and assessment of psychometric properties of PICS/PTSD in ICU survivors or families globally. We identified five tools addressing all three aspects of PICS manifestations, one tool for both physical and mental aspects of PICS, and fivefive tools for quality-of-life assessment in ICU survivors. Altogether, 25 tools assess only one aspect of PICS: five for cognitive impairment, seven for physical impairment, and 13 for mental health impairment and PTSD in ICU survivors. However, only two tools were found for PICS-family assessment. Other findings include (i) unclear validity and often limited feasibility of tools, (ii) low diagnostic accuracy of cognitive assessment tools, and (iii) evidence of appropriate psychometric properties and feasibility of psychological health assessment tools.

CONCLUSION

These results have implications for the selection and implementation of the assessment methods as a means for promoting meaningful patient-centred clinical outcomes to minimise long-term sequelae, reduce the rate of rehospitalisation, and optimise recovery after ICU discharge.

Psychological symptoms in difficult-to-sedate critical care survivors

BACKGROUND

Critical care survivors often experience symptoms of anxiety, depression, or post-traumatic stress disorder (PTSD).

AIMS

To determine the prevalence and severity of psychological symptoms during the first 6 months after discharge from the intensive care unit (ICU) and to evaluate its association with patients who are difficult to sedate during admission.

DESIGN

Descriptive, prospective analysis of psychological symptoms in survivors from medicosurgical ICU over a 2-year period.

METHODS

All ICU survivors who required mechanical ventilation (MV) for more than 24 hours were followed for 6 months after their ICU discharge. ICU outcome and complications as well as the presence of psychological symptoms, 1 to 3 to 6 months after discharge were prospectively evaluated through phone interviews comparing the incidence and intensity of patients who were difficult to sedate during their ICU stay with those who were not. Descriptive analysis and multivariate logistic regression were performed.

RESULTS

Data were obtained for 195 patients, of whom 30% experienced difficult sedation (DS). Difficult-to-sedate patients were younger (P = .001), less critically ill (APACHE II score P = .002), and more likely to engage in harmful use of alcohol (P = .001) and psychoactive/psychotropic drug abuse. They also spent longer times on MV and in the ICU (P = .001). Anxiety incidence at 1 to 3 to 6 months post-discharge was significantly higher in DS patients than in those who were not (87.7% vs 45.4%, 75.5% vs 29.0%, and 70.8% vs 23.7%; P < .01), respectively. Depression incidence was also significantly higher in the DS group (82.4% vs 43.1%, 66% vs 33.9%, and 60.4% vs 27.2%; [P = .001]) at 1 to 3 to 6 months, respectively. A higher percentage of patients in the DS group reported symptoms of PTSD at 1 month (28.1% vs 11.5%) (P = .007) when compared with non-DS group.

CONCLUSIONS

Critical care survivors who are difficult to sedate during their ICU stay are more likely to present psychological sequelae. Early identification of at-risk patients is necessary to implement appropriate preventive strategies.

RELEVANCE TO CLINICAL PRACTICE

Patients who are difficult to sedate in the ICU may develop psychological disorders upon discharge, which may negatively affect their recovery. The prevention of DS and the early detection of psychological disorders are essential to minimize its subsequent impact.

[Aftercare of ICU patients: A task for pneumology?]

As the number of patients treated in intensive care medicine increases, so does the number of those who suffer from the long-term consequences of critical illness and the consequences of a stay in an intensive care unit. For this group of patients with a post-intensive care syndrome (PICS), there are currently no specialized outpatient care structures that follow the hospital stay and possible follow-up treatment. A number of studies are researching the effectiveness of intensive care outpatient clinics nationally and internationally.After presenting the PICS and the associated complex need for care, this review article presents various model projects for outpatient follow-up care of critically ill patients. We discuss whether the field of pneumology is particularly suitable for the study of therapy control of complex clinical pictures since it has vast experience in the treatment of intensive care patients and the outpatient care of chronically ill patients.

Postintensive Care Syndrome: Feasibly Bridging Care at a Tertiary Trauma Center

BACKGROUND

Advancements in critical care management have improved mortality rates of trauma patients; however, research has identified physical and psychological impairments that remain with patients for an extended time. Cognitive impairments, anxiety, stress, depression, and weakness in the postintensive care phase are an impetus for trauma centers to examine their ability to improve patient outcomes.

OBJECTIVE

This article describes one center's efforts to intervene to address postintensive care syndrome in trauma patients.

METHODS

This article describes implementing aspects of the Society of Critical Care Medicine's liberation bundle to address postintensive care syndrome in trauma patients.

RESULTS

The implementation of the liberation bundle initiatives was successful and well received by trauma staff, patients, and families. It requires strong multidisciplinary commitment and adequate staffing. Continued focus and retraining are requirements in the face of staff turnover and shortages, which are real-world barriers.

CONCLUSIONS

Implementation of the liberation bundle was feasible. Although the initiatives were positively received by trauma patients and their families, we identified a gap in the availability of long-term outpatient services for trauma patients after discharge from the hospital.

Risk Factors Associated With Post-COVID-19 Condition: A Systematic Review and Meta-analysis

Importance

Post-COVID-19 condition (PCC) is a complex heterogeneous disorder that has affected the lives of millions of people globally. Identification of potential risk factors to better understand who is at risk of developing PCC is important because it would allow for early and appropriate clinical support.

Objective

To evaluate the demographic characteristics and comorbidities that have been found to be associated with an increased risk of developing PCC.

Data sources

Medline and Embase databases were systematically searched from inception to December 5, 2022.

Study Selection

The meta-analysis included all published studies that investigated the risk factors and/or predictors of PCC in adult (≥18 years) patients.

Data Extraction and Synthesis

Odds ratios (ORs) for each risk factor were pooled from the selected studies. For each potential risk factor, the random-effects model was used to compare the risk of developing PCC between individuals with and without the risk factor. Data analyses were performed from December 5, 2022, to February 10, 2023.

Main Outcomes and Measures

The risk factors for PCC included patient age; sex; body mass index, calculated as weight in kilograms divided by height in meters squared; smoking status; comorbidities, including anxiety and/or depression, asthma, chronic kidney disease, chronic obstructive pulmonary disease, diabetes, immunosuppression, and ischemic heart disease; previous hospitalization or ICU (intensive care unit) admission with COVID-19; and previous vaccination against COVID-19.

Results

The initial search yielded 5334 records of which 255 articles underwent full-text evaluation, which identified 41 articles and a total of 860 783 patients that were included. The findings of the meta-analysis showed that female sex (OR, 1.56; 95% CI, 1.41-1.73), age (OR, 1.21; 95% CI, 1.11-1.33), high BMI (OR, 1.15; 95% CI, 1.08-1.23), and smoking (OR, 1.10; 95% CI, 1.07-1.13) were associated with an increased risk of developing PCC. In addition, the presence of comorbidities and previous hospitalization or ICU admission were found to be associated with high risk of PCC (OR, 2.48; 95% CI, 1.97-3.13 and OR, 2.37; 95% CI, 2.18-2.56, respectively). Patients who had been vaccinated against COVID-19 with 2 doses had a significantly lower risk of developing PCC compared with patients who were not vaccinated (OR, 0.57; 95% CI, 0.43-0.76).

Conclusions and Relevance

This systematic review and meta-analysis demonstrated that certain demographic characteristics (eg, age and sex), comorbidities, and severe COVID-19 were associated with an increased risk of PCC, whereas vaccination had a protective role against developing PCC sequelae. These findings may enable a better understanding of who may develop PCC and provide additional evidence for the benefits of vaccination.

COVID-19, post-acute COVID-19 syndrome (PACS, "long COVID") and post-COVID-19 vaccination syndrome (PCVS, "post-COVIDvac-syndrome"): Similarities and differences

Worldwide there have been over 760 million confirmed coronavirus disease 2019 (COVID-19) cases, and over 13 billion COVID-19 vaccine doses have been administered as of April 2023, according to the World Health Organization. An infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can lead to an acute disease, i.e. COVID-19, but also to a post-acute COVID-19 syndrome (PACS, "long COVID"). Currently, the side effects of COVID-19 vaccines are increasingly being noted and studied. Here, we summarise the currently available indications and discuss our conclusions that (i) these side effects have specific similarities and differences to acute COVID-19 and PACS, that (ii) a new term should be used to refer to these side effects (post-COVID-19 vaccination syndrome, PCVS, colloquially "post-COVIDvac-syndrome"), and that (iii) there is a need to distinguish between acute COVID-19 vaccination syndrome (ACVS) and post-acute COVID-19 vaccination syndrome (PACVS) - in analogy to acute COVID-19 and PACS ("long COVID"). Moreover, we address mixed forms of disease caused by natural SARS-CoV-2 infection and COVID-19 vaccination. We explain why it is important for medical diagnosis, care and research to use the new terms (PCVS, ACVS and PACVS) in order to avoid confusion and misinterpretation of the underlying causes of disease and to enable optimal medical therapy. We do not recommend to use the term "Post-Vac-Syndrome" as it is imprecise. The article also serves to address the current problem of "medical gaslighting" in relation to PACS and PCVS by raising awareness among the medical professionals and supplying appropriate terminology for disease.

Post Hospital Discharge Functional Recovery of Critical Illness Survivors. Systematic Review

Background

Millions of people face critical illnesses and need to be hospitalized in an Intensive Care Unit (ICU) annually worldwide. Despite the fact that survival rates of these patients have increased, they develop various cognitive, psychological and functional impairments. This study aims to investigate the significance of the recovery interventions following intensive care unit discharge, the effectiveness of the rehabilitative protocols and their possible deficits.

Methods

MEDLINE (PubMed) and Physiotherapy Evidence Database (PEDro) were searched for studies analyzing the recovery potentials post-ICU among adults, who spent at least 48 hours at the ICU. Methodological quality of the studies was assessed via PEDro Scale.

Results

Nine randomized controlled trials were included. These took place mainly at specialized rehabilitation gyms as well as patients home environments. Studies analyses showed that treatment group showed improvement in functional ability in relation to control group. Nevertheless, differences between two groups were not statistically significant (P<0.05). The majority of studies assessed cardiorespiratory endurance and muscular strength.

Conclusions

The included rehabilitation programs were determined to be effective. Although they didn't prove any statistically significant difference between groups, quality of life enhancements and stress reduction were reported. Hence, new randomized controlled trials are required in order to provide more accurate data on the potential benefits of rehabilitation strategies among post-ICU patients.

COVID-19 severity is related to poor executive function in people with post-COVID conditions

Patients with post-coronavirus disease 2019 (COVID-19) conditions typically experience cognitive problems. Some studies have linked COVID-19 severity with long-term cognitive damage, while others did not observe such associations. This discrepancy can be attributed to methodological and sample variations. We aimed to clarify the relationship between COVID-19 severity and long-term cognitive outcomes and determine whether the initial symptomatology can predict long-term cognitive problems. Cognitive evaluations were performed on 109 healthy controls and 319 post-COVID individuals categorized into three groups according to the WHO clinical progression scale: severe-critical (n = 77), moderate-hospitalized (n = 73), and outpatients (n = 169). Principal component analysis was used to identify factors associated with symptoms in the acute-phase and cognitive domains. Analyses of variance and regression linear models were used to study intergroup differences and the relationship between initial symptomatology and long-term cognitive problems. The severe-critical group performed significantly worse than the control group in general cognition (Montreal Cognitive Assessment), executive function (Digit symbol, Trail Making Test B, phonetic fluency), and social cognition (Reading the Mind in the Eyes test). Five components of symptoms emerged from the principal component analysis: the "Neurologic/Pain/Dermatologic" "Digestive/Headache", "Respiratory/Fever/Fatigue/Psychiatric" and "Smell/ Taste" components were predictors of Montreal Cognitive Assessment scores; the "Neurologic/Pain/Dermatologic" component predicted attention and working memory; the "Neurologic/Pain/Dermatologic" and "Respiratory/Fever/Fatigue/Psychiatric" components predicted verbal memory, and the "Respiratory/Fever/Fatigue/Psychiatric," "Neurologic/Pain/Dermatologic," and "Digestive/Headache" components predicted executive function. Patients with severe COVID-19 exhibited persistent deficits in executive function. Several initial symptoms were predictors of long-term sequelae, indicating the role of systemic inflammation and neuroinflammation in the acute-phase symptoms of COVID-19."

Myokines may target accelerated cognitive aging in people with spinal cord injury: A systematic and topical review

Persons with spinal cord injury (SCI) can suffer accelerated cognitive aging, even when correcting for mood and concomitant traumatic brain injury. Studies in healthy older adults have shown that myokines (i.e. factors released from muscle tissue during exercise) may improve brain health and cognitive function. Myokines may target chronic neuroinflammation, which is considered part of the mechanism of cognitive decline both in healthy older adults and SCI. An empty systematic review, registered in PROSPERO (CRD42022335873), was conducted as proof of the lack of current research on this topic in people with SCI. Pubmed, Embase, Cochrane and Web of Science were searched, resulting in 387 articles. None were considered eligible for full text screening. Hence, the effect of myokines on cognitive function following SCI warrants further investigation. An in-depth narrative review on the mechanism of SCI-related cognitive aging and the myokine-cognition link was added to substantiate our hypothetical framework. Readers are fully updated on the potential role of exercise as a treatment strategy against cognitive aging in persons with SCI.

Intensive Care Unit Diaries: A Nurse-Led Program

BACKGROUND

Following intensive care unit stays, patients with post-intensive care syndrome can experience mental health symptoms that impact quality of life. Intensive care unit diaries have been shown to improve outcomes for patients and their families.

LOCAL PROBLEM

Identification of limited support for high volumes of intensive care unit patients and families led to implementation of an intensive care unit diary program in a 24-bed adult medical-surgical intensive care unit.

METHODS

Patients requiring mechanical ventilation with an expected intensive care unit stay of more than 24 hours were provided intensive care unit diaries. Nursing staff and patients' families entered daily descriptive narratives of patients' progress during the stay. After intensive care unit discharge, patients and families reviewed the diaries to improve acceptance of their intensive care unit experience. Project evaluation included review of patient and family follow-up calls, a staff nurse feedback survey, and project champion debriefing sessions to gauge implementation success and feasibility.

RESULTS

Twenty diaries were completed and distributed to patients or families at intensive care unit discharge. Follow-up calls illustrated support and gratitude for diaries regardless of patient outcomes. Patients reported that diaries helped fill memory gaps between intensive care unit admission and discharge. Nurse surveys and project champion debriefings confirmed that completion of intensive care unit diary entries had minimal impact on workload, eased communication, and improved staff members' coping skills.

CONCLUSION

Successful intensive care unit diary program implementation has the potential to benefit patients, families, and nursing staff for little organizational cost.

A Step Forward for Intensive Care Unit Patients: Early Mobility Interventions and Associated Outcome Measures

Background

Critical illness survivors have impairments across physical, psychological, and cognitive health domains known as post–intensive care syndrome. Although physical activity can improve outcomes across all health domains, most intensive care unit early mobility studies focus solely on physical outcomes.

Objective

To explore the role of early mobility for adult patients in the intensive care unit by analyzing early mobility intervention studies with physical, psychological, or cognitive outcome measures.

Methods

This integrative review used Whittemore and Knafl’s methodology and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. CINAHL, Embase, PubMed, PsycINFO, and Scopus databases were searched for primary research articles published from 2005 through 2021 on adult intensive care unit early mobility interventions evaluated by physical, cognitive, or psychological outcome measures during or after intervention delivery. Interventions comprising only passive mobility were excluded.

Results

Of 1009 articles screened, 20 were included. Variations in outcome measures, measurement timing, instruments, and control groups made synthesis difficult. No study evaluated an intervention using outcome measures from all 3 health domains. Five studies measured physical and cognitive outcomes; 6 studies measured physical and psychological outcomes.

Conclusion

Early mobility is primarily addressed objectively and unidimensionally, limiting understanding of the implications of early mobility for patients. Post–intensive care syndrome prevention begins in the intensive care unit; early mobility is a promising intervention for targeting multiple risk factors. Studies that measure outcomes in all health domains during or after early mobility are needed to better evaluate the comprehensive effects of early mobility.

National mapping of municipality-based rehabilitation services for patients recovering from COVID-19 in Denmark: a cross-sectional study

Background/aims

A lack of knowledge exists as to how municipalities are meeting the rehabilitation needs of patients recovering from COVID-19. This poses a potential barrier when referring patients for rehabilitation. The aim of this study was to map and describe municipality-based rehabilitation services for patients recovering from COVID-19 in Denmark.

Methods

This was a cross-sectional, nation-wide survey. Key staff members from all 98 municipalities in Denmark were invited to participate. Participants had insight into the organisation and professional content of municipal rehabilitation. Structured telephone interviews were conducted by three interviewers between October and November 2020. The interview guide consisted of items that asked about the availability, content and organisation of municipality-based rehabilitation services.

Results

A total of 91 municipalities (93% response rate) participated in the study. Rehabilitation could be provided within pre-existing services in 98% of municipalities and 93% systematically assessed individual rehabilitation needs using a variety of measurement methods. All municipalities reported that they had services in place to provide functional rehabilitation (eg gait training) and over 90% provided physical, cognitive and lifestyle-related rehabilitation. In contrast, 70% could provide COVID-19 education and 64% psychological therapy. Overall, 32% of municipalities had not received referrals for COVID-19 rehabilitation. Of the 62 municipalities that had COVID-19 rehabilitation experience, 73% rated the degree to which they could deliver coherent and coordinated rehabilitation for patients with complex rehabilitation needs as high or very high.

Conclusions

Overall, Danish municipalities reported that pre-existing services are in place to provide relevant, individualised rehabilitation for patients recovering from COVID-19. Nonetheless, future efforts should ensure that patient education is established, in step with health care providers accumulating knowledge, as well as integrated referral pathways between sectors, to deliver rehabilitation to patients with complex needs. Further, implementation of a national data collection strategy would strengthen and inform future development of relevant services both nationally and internationally.

Post-Intensive Care Syndrome Prevalence Six Months after Critical Covid-19: Comparison between First and Second Waves

OBJECTIVE

To explore the impact of improved intensive care for COVID-19 patients on the prevalence of post-intensive care syndrome (PICS).

DESIGN

Ambispective cohort study.

PATIENTS

Post-intensive care unit COVID-19 patients from the first and second waves of COVID-19.

METHODS

Patients were evaluated at 6 months after infection. PICS was defined as the presence of a 1-min sit-to-stand test (1STS) score < 2.5th percentile or a Symbol Digit Modalities Test (SDMT) below the 2 standard deviation cut-off, or a Hospital Anxiety and Depression Scale score ≥ 11.

RESULTS

A total of 60 patients were included (34 from wave 1 and 26 from wave 2). Intensive care unit management improved between waves, with shorter duration of orotracheal intubation (7 vs 23.5 days, p = 0.015) and intensive care unit stay (6 vs 9.5 days, p = 0.006) in wave 2. PICS was present in 51.5% of patients after wave 1 and 52% after wave 2 (p = 0.971). Female sex and diabetes were significantly associated with PICS by multivariate analysis.

CONCLUSION

Approximately half of post-intensive care unit COVID-19 patients have 1 or more impairments consistent with PICS at 6 months, with an impact on quality of life and participation. Improved intensive care unit management was not associated with a decrease in the prevalence of PICS. Identification of patients at risk, particularly women and diabetic patients, is essential. Further studies of underlying mechanisms and the need for rehabilitation are essential to reduce the risk of PICS.

Feasibility of Extracting Meaningful Patient Centered Outcomes From the Electronic Health Record Following Critical Illness in the Elderly

Background

Meaningful patient centered outcomes of critical illness such as functional status, cognition and mental health are studied using validated measurement tools that may often be impractical outside the research setting. The Electronic health record (EHR) contains a plethora of information pertaining to these domains. We sought to determine how feasible and reliable it is to assess meaningful patient centered outcomes from the EHR.

Methods

Two independent investigators reviewed EHR of a random sample of ICU patients looking at documented assessments of trajectory of functional status, cognition, and mental health. Cohen's kappa was used to measure agreement between 2 reviewers. Post ICU health in these domains 12 month after admission was compared to pre- ICU health in the 12 months prior to assess qualitatively whether a patient's condition was “better,” “unchanged” or “worse.” Days alive and out of hospital/health care facility was a secondary outcome.

Results

Thirty six of the 41 randomly selected patients (88%) survived critical illness. EHR contained sufficient information to determine the difference in health status before and after critical illness in most survivors (86%). Decline in functional status (36%), cognition (11%), and mental health (11%) following ICU admission was observed compared to premorbid baseline. Agreement between reviewers was excellent (kappa ranging from 0.966 to 1). Eighteen patients (44%) remained home after discharge from hospital and rehabilitation during the 12- month follow up.

Conclusion

We demonstrated the feasibility and reliability of assessing the trajectory of changes in functional status, cognition, and selected mental health outcomes from EHR of critically ill patients. If validated in a larger, representative sample, these outcomes could be used alongside survival in quality improvement studies and pragmatic clinical trials.

Optimal timing of introducing mobilization therapy for ICU patients with sepsis

Background

For patients admitted to the intensive care unit (ICU) with sepsis, mobilization therapy during ICU stay can improve their outcomes during and after the ICU stay. However, little is known about the optimal timing of introducing mobilization therapy.

Methods

This is a retrospective cohort study using data from a tertiary medical center in Japan during 2013–2017. We included patients aged ≥ 18 years who were admitted to the ICU with sepsis based on the Sepsis-3 criteria. We defined early mobilization (EM) as the rehabilitation at the level of sitting on the edge of the bed or more within the first 3 days of the patients’ ICU stay. Patients were divided into the EM and non-EM groups. The primary outcomes were in-hospital mortality and ambulatory dependence at hospital discharge. We estimated the effects of EM by stabilized inverse probability weighting (sIPW). We then tested alternative definitions of EM by changing the cutoff in days to mobilization by 1-day increments from 2 to 7 days to investigate the optimal timing of mobilization.

Results

Our study sample consisted of a total of 296 septic patients, including 96 patients in the EM group and 200 patients in the non-EM group. In the sIPW model, the adjusted OR for in-hospital mortality in the EM group compared to the non-EM group was 0.22 [95% CI 0.06–0.88], and the adjusted OR for ambulatory dependence at the hospital discharge was 0.24 [95% CI 0.09–0.61]. When alternative definitions of EM were tested, patients who achieved mobilization within the first 2–4 days of their ICU stays had better outcomes.

Conclusions

Achieving mobilization within the first 3 days of ICU stay was significantly associated with better outcomes. Patients with sepsis might benefit most from achieving mobilization within 2–4 days. Further studies are warranted to validate the findings.

Emerging Knowledge of the Neurobiology of COVID-19

Many patients with COVID-19 will experience acute or longer-term neuropsychiatric complications. The neurobiological mechanisms behind these are beginning to emerge; however, the neurotropic hypothesis is not strongly supported by clinical data. The inflammatory response to SARS-CoV-2 is likely to be responsible for delirium and other common acute neuropsychiatric manifestations. Vascular abnormalities such as endotheliopathies contribute to stroke and cerebral microbleeds, with their attendant neuropsychiatric sequelae. Longer-term neuropsychiatric syndromes fall into 2 broad categories: neuropsychiatric deficits occurring after severe (hospitalized) COVID-19 and "long COVID," which occurs in many patients with a milder acute COVID-19 illness.

Socio-Ecologic Perspective: Barriers Complicating Post-Intensive Care Syndrome Mitigation

Objective:Post-intensive care syndrome (PICS) is a phenomenon whereby survivors of an intensive care unit (ICU) admission subsequently experience issues with physical, cognitive, or mental health status persisting beyond the acute hospitalization. Risk factors for developing PICS include prolonged mechanical ventilation with sedation and immobility. PICS is a devastating illness that negatively alters the life path of many individuals with tremendous economic impact. Methods: This qualitative study employed a grounded theory approach to understand the systemic barriers blocking mitigation and treatment of PICS in all seven ICUs across Essex County, New Jersey (NJ) through semi-scripted interviews conducted with 11 members of the healthcare teams with at least one from each site. Thematic analysis was performed with open, axial, and selective coding. Results: Applying socio-ecologic viewpoint to data illustrate significant barriers on both an interpersonal and organizational level that decrease the operationalization of PICS mitigation measures as identified by healthcare providers. Of those interviewed, eight (73%) were physicians and the remaining were nurses. Significant thematic issues included understanding the risk factors of PICS but feeling powerless to institute mitigation efforts; experiencing lack of enthusiasm due to the absence of institutionalized mitigation protocols; noting frustration about closing the gap between academic recommendations and the ability to operationalize these appropriately; and feeling unable to effectuate meaningful change. Conclusion: Providing education to the target population and healthcare provider stakeholders regarding the barriers against PICS mitigation can alter the status quo.

Psychological risk factors that characterize acute stress disorder and trajectories of posttraumatic stress disorder after injury: a study using latent class analysis

Background

The course and different characteristics of acute and posttraumatic stress disorder (ASD, PTSD) in trauma populations are unclear.

Objective

The aims were to identify longitudinal trajectories of PTSD, to establish a risk profile for ASD and PTSD based on patients' sociodemographic, clinical, and psychological characteristics, and to study the effect of ASD and dissociation on PTSD during 12 months after trauma.

Method

Patients completed questionnaires after inclusion and at 3, 6, 9, and 12 months afterwards. Trajectories were identified using repeated measures latent class analysis (RMLCA). The risk profile was based on a ranking of importance of each characteristic using Cohen's d effect sizes and odds ratios. The impact of ASD and dissociation on PTSD was examined using logistic regression analyses.

Results

Altogether, 267 patients were included. The mean age was 54.0 (SD = 16.1) and 62% were men. The prevalence rate of ASD was approximately 21.7% at baseline, and 36.1% of trauma patients exhibited PTSD at 12 months after injury. Five trajectories were identified: (1) no PTSD symptoms, (2) mild, (3) moderate, (4) subclinical, and (5) severe PTSD symptoms. These trajectories seemed to remain stable over time. Compared with patients in other trajectories, patients with ASD and (subclinical) PTSD were younger and scored higher on anxiety, depressive symptoms, neuroticism, and trait anxiety. Regarding dissociation symptoms, inability to recall memories about the event was significantly more present than an altered sense of reality, (105 (40.7%) versus 56 (21.7%), p = .031), although that symptom had the strongest likelihood for PTSD. Patients with dissociation were significantly at risk for PTSD than patients without dissociation (OR = 4.82; 95%CI: 1.91-12.25).

Conclusions

Psychological factors characterized ASD and trajectories of PTSD during 12 months post-trauma. Healthcare providers who are aware of these findings could early identify patients at risk for ASD and PTSD and refer them for patient-centred interventions.

Post-ICU Syndrome in a Cohort of COVID-19 Survivors in New York City

RATIONALE

The coronavirus disease 2019 (COVID-19) pandemic has led to a dramatic increase in the number of survivors of critical illness. These survivors are at increased risk of physical, psychological, and cognitive impairments known collectively as Post-Intensive Care Syndrome (PICS). Little is known about the prevalence of PICS in COVID-19 survivors.

OBJECTIVES

To report the prevalence of physical, psychological, and cognitive impairment among COVID-19 intensive care unit (ICU) survivors receiving follow-up care in an ICU recovery clinic, to assess for associations between PICS and ICU-related factors, and to compare the cohort of ICU survivors who attended post-ICU clinic to a cohort of ICU survivors who did not.

METHODS

We performed a retrospective cohort study of COVID-19 ICU survivors admitted from March to May 2020 who were subsequently seen in a post-ICU recovery clinic in New York City. We abstracted medical chart data on available clinical screening instruments for physical, psychological, and cognitive impairment. Associations between these outcomes and care-related variables were tested. Baseline characteristics and in-hospital treatments of the post-ICU clinic cohort were compared to COVID-19 ICU survivors from the same institution who were not seen in post-ICU clinic.

RESULTS

87 COVID-19 ICU survivors were seen in our post-ICU recovery clinic. The median age was 62 years and 74% were male. The median length of hospitalization was 51 days and the median length of ICU stay was 22 days. At the post-ICU follow-up visit, 29%, 21%, and 13% of patients reported clinically significant levels of depressive symptoms, anxiety, and post-traumatic stress disorder symptoms, respectively. 25% had cognitive impairment. The overall prevalence of PICS was 90%. There were no associations between length of ICU stay, delirium, exposure to benzodiazepines, steroids, or systemic paralytics with positive screens for physical, psychological, or cognitive impairment. Baseline characteristics and ICU-related factors were similar in the cohort of COVID-19 ICU survivors who attended ICU recovery clinic and those who did not.

CONCLUSION

PICS is common in COVID-19 survivors. We did not find any association with length of ICU stay, the use of benzodiazepines, steroids, or paralytics.

Usefulness of Pulmonary Rehabilitation in Non-small Cell Lung Cancer Patients Based on Pulmonary Function Tests and Muscle Analysis Using Computed Tomography Images

Purpose

The usefulness of rehabilitation in patients with reduced lung function before lung surgery remains unclear, and there is no adequate method for evaluating the effect of rehabilitation. We aimed to evaluate the usefulness of rehabilitation in patients with non–small cell lung cancer (NSCLC) undergoing lung cancer surgery.

Materials and Methods

We retrospectively analyzed the medical records of NSCLC patients at Korea University Guro Hospital between 2018 and 2020. Patients were divided into two groups depending on whether they underwent rehabilitation. Pulmonary function test data and muscle determined using chest computed tomography images were analyzed. Because the baseline characteristics were different between the two groups, propensity score matching was performed.

Results

Of 325 patients, 75 (23.1%) and 250 (76.9%) were included in the rehabilitation and non-rehabilitation (control) groups, respectively. The rehabilitation group had a worse general condition at baseline. After propensity score matching, 45 patients remained in each group. Pulmonary function (forced expiratory volume in 1 second, %) (p=0.001) and the Hounsfield unit of erector spinae muscle (p=0.001) were better preserved in the rehabilitation group. Muscle loss of 3.4% and 0.6% was observed in the control and rehabilitation groups, respectively (p=0.003). In addition, the incidence of embolic events was lower in the rehabilitation group (p=0.044).

Conclusion

Pulmonary rehabilitation is useful in patients with NSCLC undergoing lung surgery. Pulmonary rehabilitation preserves lung function, muscle and reduces embolic events after surgery. Pulmonary rehabilitation is recommended for patients with NSCLC undergoing surgery.

Palliative Care Principles and Anesthesiology Clinical Practice: Current Perspectives

Background

Palliative care is a person-centered approach aiming to relieve patient’s health-related suffering and it is often needed when caring for critically ill patients to manage symptoms and identify goals of care.

Aim

To describe the integration of palliative care principles in anesthesiology clinical practice, within and outside the ICU and to analyze the additional challenges that COVID-19 pandemic is posing in this context.

Methods

For the purpose of this review, PubMed database was searched for studies concerning palliative care and end of life care, in contexts involving anesthesiologists and intensivists, published in the last 5 years.

Results

Anesthesiologists and intensivists integrate palliative care within their daily practice providing symptoms management as well as family counseling. High-quality communicational skills are fundamental for anesthesiologists and intensivists especially when interfacing with surrogate decision makers in the ICU or with patients in the preoperative setting while discussing goals of care. Coronavirus disease 2019 (COVID-19) pandemic has challenged many aspects of palliative care delivery: reduced family presence within the ICU, communication with families through phone calls or video calls, patient–physician relationship mediated by bulky personal protective equipment and healthcare workers physical and psychological distress due to the increased workload and limitations in resources are some of the most evident.

Conclusion

Anesthesiologists and intensivists are increasingly facing challenging clinical situations where principles and practice of palliative care have to be applied. In this sense, increasing knowledge on palliative care and providing specific training would allow to deliver high-quality symptom management, family counseling and end of life guidance in critical care settings. COVID-19 pandemic sets additional difficulties to palliative care delivery.

Quality of life of COVID-19 critically ill survivors after ICU discharge: 90 days follow-up

PURPOSE

The onset of the coronavirus disease 19 (COVID-19) pandemic in Italy induced a dramatic increase in the need for intensive care unit (ICU) beds for a large proportion of patients affected by COVID-19-related acute respiratory distress syndrome (ARDS). The aim of the present study was to describe the health-related quality of life (HRQoL) at 90 days after ICU discharge in a cohort of COVID-19 patients undergoing invasive mechanical ventilation and to compare it with an age and sex-matched sample from the general Italian and Finnish populations. Moreover, the possible associations between clinical, demographic, social factors, and HRQoL were investigated.

METHODS

COVID-19 ARDS survivors from 16 participating ICUs were followed up until 90 days after ICU discharge and the HRQoL was evaluated with the 15D instrument. A parallel cohort of age and sex-matched Italian population from the same geographic areas was interviewed and a third group of matched Finnish population was extracted from the Finnish 2011 National Health survey. A linear regression analysis was performed to evaluate potential associations between the evaluated factors and HRQoL.

RESULTS

205 patients answered to the questionnaire. HRQoL of the COVID-19 ARDS patients was significantly lower than the matched populations in both physical and mental dimensions. Age, sex, number of comorbidities, ARDS class, duration of invasive mechanical ventilation, and occupational status were found to be significant determinants of the 90 days HRQoL. Clinical severity at ICU admission was poorly correlated to HRQoL.

CONCLUSION

COVID-19-related ARDS survivors at 90 days after ICU discharge present a significant reduction both on physical and psychological dimensions of HRQoL measured with the 15D instrument.

Post Intensive Care Syndrome (PICS): an overview of the definition, etiology, risk factors, and possible counseling and treatment strategies

INTRODUCTION

Post-intensive care syndrome (PICS) has only recently been recognized as a new clinical entity in patients surviving their intensive care unit (ICU) stay due to critical illness. With increasing survival rates of ICU patients worldwide, there is a rising interest regarding post-ICU recovery.

AREAS COVERED

First, based on the current literature a definition is provided of PICS, including the domains of impairments that comprise PICS along with the etiology and risk factors. Second, preventive measures and possible treatment strategies integrated in the follow-up care are described. Third, the authors will discuss the current SARS-Cov-2 pandemic and the increased risk of PICS in these post-ICU patients and their families.

EXPERT OPINION

PICS is a relatively new entity, which not only encompasses various physical, cognitive, and psychological impairments but also impacts global health due to long-lasting detrimental socioeconomic burdens. Importantly, PICS also relates to caregivers of post-ICU patients. Strategies to reduce this burden will not only be needed within the ICU setting but will also have to take place in an interdisciplinary, multifaceted approach in primary care settings. Additionally, the SARS-Cov-2 pandemic has a high burden on post-ICU patients and their relatives.

Safety and Feasibility of an Interdisciplinary Treatment Approach to Optimize Recovery From Critical Coronavirus Disease 2019

Supplemental Digital Content is available in the text.

OBJECTIVES:

Examine the safety and feasibility of a multimodal in-person or telehealth treatment program, administered in acute recovery phase for patients surviving critical coronavirus disease 2019.

DESIGN:

Pragmatic, pre-post, nonrandomized controlled trial with patients electing enrollment into one of the two recovery pathways.

SETTING:

ICU Recovery Clinic in an academic medical center.

PATIENTS:

Adult patients surviving acute respiratory failure due to critical coronavirus disease 2019.

INTERVENTIONS:

Patients participated in combined ICU Recovery clinic and 8 weeks of physical rehabilitation delivered: 1) in-person or 2) telehealth. Patients received medical care by an ICU Recovery Clinic interdisciplinary team and physical rehabilitation focused on aerobic, resistance, and respiratory muscle training.

MEASUREMENTS AND MAIN RESULTS:

Thirty-two patients enrolled with mean age 57 ± 12, 62% were male, and the median Sequential Organ Failure Assessment score was 9.5. There were no differences between the two groups except patients in telehealth pathway (n = 10) lived further from clinic than face-to-face patients (162 ± 60 vs 31 ± 47 kilometers, t = 6.06, p < 0.001). Four safety events occurred: one minor adverse event in the telehealth group, two minor adverse events, and one major adverse event in the in-person group. Three patients did not complete the study (two in-person and one telehealth). Six-minute walk distance increased to 101 ± 91 meters from pre to post (n = 29, t = 6.93, p < 0.0001), which was similar between the two groups (110 vs 80 meters, t = 1.34, p = 0.19). Self-reported levels of anxiety, depression, and distress were high in both groups with similar self-report quality of life.

CONCLUSIONS:

A multimodal treatment program combining care from an interdisciplinary team in an ICU Recovery Clinic with physical rehabilitation is safe and feasible in patients surviving the ICU for coronavirus disease 2019 acute respiratory failure.

Postintensive Care Syndrome in Survivors of Critical Illness Related to Coronavirus Disease 2019: Cohort Study From a New York City Critical Care Recovery Clinic

OBJECTIVE

Determine the characteristics of postintensive care syndrome in the cognitive, physical, and psychiatric domains in coronavirus disease 2019 ICU survivors.

DESIGN

Single-center descriptive cohort study from April 21, to July 7, 2020.

SETTING

Critical care recovery clinic at The Mount Sinai Hospital in New York City.

PATIENTS

Adults who had critical illness due to coronavirus disease 2019 requiring an ICU stay of 7 days or more and who agreed to a telehealth follow-up in the critical care recovery clinic 1-month post hospital discharge.

INTERVENTIONS

None.

MEASURES AND MAIN RESULTS

Patient-reported outcome measures assessing physical and psychiatric domains were collected electronically, a cognitive test was performed by a clinician, and clinical data were obtained through electronic medical records. Outcome measures assessed postintensive care syndrome symptoms in the physical (Modified Rankin Scale, Dalhousie Clinical Frailty Scale, Neuro-Quality of Life Upper Extremity and Lower Extremity Function, Neuro-Quality of Life Fatigue), psychiatric (Insomnia Severity Scale; Patient Health Questionnaire-9; and Posttraumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition), and cognitive (Telephone Montreal Cognitive Assessment) domains. The 3-Level Version of Euro-QoL-5D was used to assess the physical and psychiatric domains. A diagnosis of postintensive care syndrome was made in cases with evidence of impairment in at least one postintensive care syndrome domain. We included 45 patients with a mean (sd) age of 54 (13) years, and 73% were male. Ninety-one percent of coronavirus disease 2019 ICU survivors fit diagnostic criteria for postintensive care syndrome. 86.7 % had impairments in the physical domain, 22 (48%) reported impairments in the psychiatric domain, and four (8%) had impairments on cognitive screening. We found that 58% had some degree of mobility impairment. In the psychiatric domain, 38% exhibited at least mild depression, and 18 % moderate to severe depression. Eighteen percent presented Posttraumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, scores suggestive of posttraumatic stress syndrome diagnosis. In the Telephone Montreal Cognitive Assessment, 9% had impaired cognition.

CONCLUSIONS

Survivors of critical illness related to coronavirus disease 2019 are at high risk of developing postintensive care syndrome. These findings highlight the importance of planning for appropriate post-ICU care to diagnose and treat this population.

Patients' experience while transitioning from the intensive care unit to a ward

BACKGROUND

Intensive care unit (ICU) patients can experience emotional distress and post-traumatic stress disorder when they leave the ICU, also referred to as post-intensive care syndrome. A deeper understanding of what patients go through and what they need while they are transitioning from the ICU to the general ward may provide input on how to strengthen patient-centred care and, ultimately, contribute to a positive experience.

AIM

To describe the patients' experience while transitioning from the ICU to a general ward.

DESIGN

A descriptive qualitative study.

METHOD

Data were gathered through in-depth interviews and analysed using a qualitative content analysis. The qualitative study was reported in accordance with the Consolidated Criteria for Reporting Qualitative Research guidelines.

FINDINGS

Forty-eight interviews were conducted. Impact on emotional well-being emerged as a main theme, comprising four categories with six subcategories.

CONCLUSION

Transition from the ICU can be a shock for the patient, leading to the emergence of a need for information, and an impact on emotional well-being that has to be planned for carefully and addressed prior to, during, and following transition from the ICU to the general ward.

RELEVANCE TO CLINICAL PRACTICE

It is essential that nurses understand patients' experiences during transfer, identifying needs and concerns to be able to develop and implement new practices such as ICU Liaison Nurse or Nurse Outreach for the follow-up of these patients, the inclusion of a consultant mental health nurse, and the application of patient empowerment during ICU discharge.
