Post-intensive Care Syndrome Research Articles

Prevalence of and risk factors analysis for post-intensive care syndrome among survivors of critical care during 3-month longitudinal follow-up.

Patients discharged from the intensive care unit (ICU) can experience post-intensive care syndrome (PICS), which is comprised of cognitive, physical and psychological impairments. The objective of this study was to identify the prevalence of and risk factors associated with all three domains of PICS at the first and third month after ICU discharge. A prospective descriptive-analytic study was conducted in two ICUs of a Chinese university hospital. We used the Healthy Aging Brain Care Monitor Self-Report Chinese version, a scale from 1 to 57, with 57 indicating the worst outcome, to comprehensively assess PICS at the first and third month follow-ups after patients left the ICU. We performed an analysis of stepwise multiple linear regression to explore the relationship between risk factors and PICS. We enrolled 654 and 584 participants at the first- and third-month follow-ups, respectively. More than 60% of patients experienced different degrees of PICS, with the most severe impairment being in the physical domain. We classified risk factors associated with PICS, categorized as patient-related, disease-related, and ICU-related factors. Among these risk factors, only being the main income provider for the family, the diagnosis of digestive system disease, trauma and the number of invasive catheters at ICU discharge significantly predicted PICS at both follow-ups. ICU-related risk factors should be given greater attention, given their potential for modification. The prevalence and severity of PICS were high in this population after their ICU stay. ICU nurses and medical staff members should collaborate to pay more attention to the comprehensive risk factors and implement targeted preventive measures. ICU staff must have a holistic view of PICS and a comprehensive understanding of its risk factors to proactively evaluate patients at high risk of PICS upon admission to the hospital.

Guidelines for safe extubation and respiratory rehabilitation in the intensive care unit

Safe extubation and effective respiratory rehabilitation are pivotal in the recovery of critically ill patients in the intensive care unit (ICU). Extubation readiness is determined by assessing respiratory function, airway patency, neurological status, and hemodynamic stability. Tools such as spontaneous breathing trials (SBTs) and the cuff leak test provide valuable insights, while neurological and hemodynamic evaluations further guide decision-making. Ensuring the resolution of the primary illness is critical to minimize the risk of extubation failure and its associated complications. The process of extubation involves meticulous preparation and technique to ensure a smooth transition from mechanical ventilation. Pre-extubation interventions, including secretion management and corticosteroid administration for high-risk patients, are vital. Techniques like gradual cuff deflation and tube removal during peak inspiration, coupled with positioning strategies, reduce complications such as aspiration and airway obstruction. Post-extubation respiratory support, including high-flow nasal cannula (HFNC) and non-invasive ventilation (NIV), plays a crucial role in stabilizing high-risk patients and preventing reintubation. Rehabilitation strategies focus on early mobilization, inspiratory muscle training, and pulmonary physiotherapy to enhance recovery and prevent long-term sequelae. Nutritional optimization is emphasized to counteract muscle weakness and promote tissue repair. Continuous monitoring for respiratory distress and addressing psychological impacts, such as post-intensive care syndrome (PICS), are integral to comprehensive care. Evidence-based protocols, individualized care plans, and multidisciplinary collaboration are essential to improving patient outcomes and reducing ICU-related morbidity and mortality.

Rehabilitation Assessment of Post Intensive Care Syndrome

The awareness of symptoms experienced after intensive care seems to have been extensively studied since the pandemic wave in 2019. The persistence or new occurrence of symptoms after intensive care is diagnosed as post-intensive care syndrome (PICS). The syndrome encloses multiple system disorders and therefore requires thorough utilization of assessment tools, which unfortunately have no standard clinical practice guidelines. Several subdomains that are crucial for assessment include physical, cognitive, and mental functions. Other aspects to be observed include quality of life, physical examination, and functional tests, particularly those related to reduced cardiorespiratory endurance. This review aimed to highlight the most notable list of tools to be used in the outpatient assessment setting of PICS. The feasibility was also tested in a recent workshop session for physical medicine and rehabilitation specialists, and it was possible to accomplish this in 30 min. Until a consensus is reached on the PICS assessment, it is strongly suggested that practitioners exercise these tools and use them in daily practice.

Post-Intensive Care Syndrome: functional impairments of critical illness survivors

With a decrease in mortality of critically ill patients in recent years, intensive care medicine research has shifted its focus on functional impairments of intensive care units (ICU) survivors. ICU survivorship is characterized by long-term impairments of cognition, mental health, and physical health. Since 2012, these impairments have been summarized with the umbrella term Post-Intensive Care Syndrome (PICS). Mental health impairments frequently entail new are aggravated symptoms of depression, anxiety, and posttraumatic stress disorder. Beyond impairments in the three PICS domains, critical illness survivors frequently suffer from chronic pain, dysphagia, and nutritional deficiencies. Furthermore, they have ahigher risk for osteoporosis, bone fractures, and diabetes mellitus. Taken together, these sequelae reduce their health-related quality of life. Additionally, ICU survivors are challenged by social problems such as isolation, economic problems such as treatment costs and lost earnings, and return to previous employment. Yet, patients and caregivers have described post-ICU care as inadequate and fragmented. ICU follow-up clinics could improve post-ICU care, but there is insufficient evidence for their effectiveness. Thus far, large high-quality trials with multicomponent and interdisciplinary post-ICU interventions have mostly failed to improve patient outcomes. Hence, preventing PICS and minimizing risk factors by optimizing ICU care is crucial, e.g. by implementing the ABCDE bundle. Future studies need to identify effective components of post-ICU recovery interventions and determine which patient populations may benefit most from ICU recovery services.

Critical Care Clinicians' Knowledge of Post-Intensive Care Syndrome.

The term post-intensive care syndrome refers to a group of symptoms that commonly occur after intensive care unit discharge, leading to worsening physical or mental health. The incidence of this syndrome is increasing. Critical care clinicians can play a pivotal role in improving patient outcomes through knowledge of post-intensive care syndrome risk factors and symptoms. To explore critical care clinicians' current knowledge of post-intensive care syndrome as a basis for developing critical care educational interventions. This quantitative, cross-sectional, observational pilot study was conducted to survey critical care physicians, nurses, nurse practitioners, and physician assistants at a university hospital on their knowledge of post-intensive care syndrome symptoms and risk factors and their confidence in their ability to recognize the condition. A total of 51 clinicians completed the survey. The overall levels of knowledge and confidence regarding post-intensive care syndrome risk factors and symptoms were low, with no significant differences found by clinician role. These findings support the need for interprofessional education on post-intensive care syndrome risk factors and early identification of symptoms in the critical care setting.

Post-ICU Syndrome and the Importance of Humanization in Intensive Care

Humanization in the ICU has become a central topic over the last decade. New research focuses on technologies such as virtual reality and music therapy, as well as on practices like family presence during and after ICU stays, open-door policies, and monitoring of both family members and healthcare personnel. Psychiatric disorders, including depression, post-traumatic stress, anxiety, and delirium, are prevalent in ICU survivors and contribute to post-ICU syndrome. This research aimed to determine the role of humanization in critical care, with a secondary objective of evaluating the impact of open-door policies on critically ill patients. Analyses, results tables, and conclusions are presented. Humanization encompasses improvements and new associated concepts such as end-of-life care, personalized ICU-VIP care, and virtual reality in the ICU. Flexibility is crucial to address all factors that affect long-term neuropsychiatric outcomes. Humanizing the intensive care unit improves communication and information flow, ultimately reducing delirium and neuropsychiatric symptoms.

Pharmacist Impact in a Post Neuro Intensive Care Virtual Clinic (PREVAIL).

Background: Traditional Post-Intensive Care Recovery Clinics (PIRCs) often exclude neurocritical care patients. In 2020, a multidisciplinary team started Post Neuro Intensive Care Virtual Clinic (PREVAIL) that uses telemedicine to provide consultative care for patients with a primary neurologic injury who are at risk for post-intensive care syndrome. During clinic, critical care pharmacists perform medication reconciliations and provide drug therapy recommendations. Objectives: The objective of this observational review is to describe the pharmacists' interventions and role in a novel PIRC. Methods: A retrospective, observational review was conducted for patients who were seen in PREVAIL from December 2020 to January 2022. The pharmacist completed a medication reconciliation and provided drug therapy recommendations. Results: Amongst fifty-two PREVAIL patients, the most common neurologic diagnosis was intracerebral hemorrhage, seizures, and acute ischemic stroke. All patients were mechanically ventilated during their ICU stay, with a median ICU length of stay of 17 days [IQR 10-26]. After medication reconciliation, 93% of patients required adjustments to their medication list. After patient examination, 89% of patients required a drug therapy recommendation, with a median of three interventions per patient. Various medication classes were intervened on, most frequently antipsychotics, anti-seizure medications, antihypertensives, anticoagulants, neuromodulators, and antidepressants. Conclusion: This is the first study to evaluate pharmacist contributions at a consultative telemedicine PIRC that focuses on providing care for patients with a primary neurologic injury. PREVAIL pharmacists have a crucial role in the multidisciplinary team. Future research is required to determine the pharmacist's impact on clinical outcomes.

Разработка и валидация ПИТС-индекса для оценки тяжести синдрома последствий интенсивной терапии: описательное проспективное несравнительное когортное исследование

INTRODUCTION: The post intensive care syndrome (PICS) is a clinical manifestation of “learned non-use” phenomena, resulting from the application of metabolic rest strategies such as bed rest, sedation, and ventilation. This leads to prolonged, multifocal dysfunction in vital functions. The lack of standardized diagnostic methods for this syndrome limits its study. For the diagnosis of PICS, we combined 15 signs of vital function disturbances that have the greatest impact on quality of life, with a scoring value of 0.5–1. The sum of these symptoms has been designated as the PICS-index. OBJECTIVE: To develop a scale for calculating the PICS-index with stratification of its values into three ranges of severity: mild, moderate and severe. MATERIALS AND METHODS: A descriptive, prospective, and unmatched cohort study was conducted on 169 patients who had a high dependency on medical care and were admitted to a rehabilitation center between 2022 and 2023. RESULTS: Using the PICS-index, showed that 100 % of patients who spent more than 72 hours in the ICU during the early recovery period (up to 6 months) developed PICS, with a predominance of moderate cases (35–52 %). The proportion of severe PICS forms reached its maximum (37 %) between 3 and 6 months. In the late recovery phase (more than 6 months), mild PICS forms were predominant (45 %). The severity of PICS was influenced by the duration of ICU stay and the timing of mechanical ventilation, but not the age of patients. CONCLUSIONS: The PICS-index is a clinically effective tool for the multidisciplinary diagnosis and assessment of the severity and progression of PICS. Using the PICS-index, we have devised a method for evaluating the predominance of specific signs. The most common signs are disturbance of the gravitational gradient, polyneuromyopathy, dysphagia. This confirms the essence of PICS as a clinical manifestation of the "learned non-use" phenomenon.

Incidence and risk factors of Post-intensive care syndrome (PICS) in surgical ICU survivors: a prospective Chinese cohort study

BackgroundPost-intensive care syndrome (PICS) is a term coined by the Society of Critical Care Medicine to describe the psychological, cognitive, and physical dysfunction that ICU survivors may experience. Although surgical patients represent a substantial proportion of ICU survivors, studies describing PICS in this specific population remain limited. This study aims to determine the incidence and independent risk factors associated with PICS among surgical ICU survivors in a Chinese cohort.MethodsThe study was a prospective cohort study of critically ill surgical patients who were discharged from the ICU at the First Affiliated Hospital of Sun Yat-sen University between August 2021 and June 2022. Demographic characteristics, disease-related information, and ICU treatment were collected, and enrolled participants were followed up within six months after ICU discharge. The Chinese version of the Medical Outcomes Study 36-item Short-Form Health Survey (SF-36) and the Short Memory Questionnaire (SMQ) were used to assess PICS. The physical component summary (PCS) and the mental component summary (MCS) were averaged from the corresponding four-dimension scores in the SF-36. PICS diagnosis was determined based on the presence of at least one of the following: physiological dysfunction (defined as PCS reductions greater than 10), psychological dysfunction (defined as MCS reductions greater than 10), or cognitive dysfunction (defined as SMQ reductions and scores less than 40 at six months). PICS diagnosis was based on the presence of at least one of the following: physiological, psychological, or cognitive dysfunction.ResultsA total of 565 patients were screened in this study, and 83 were enrolled after applying the inclusion and exclusion criteria. Overall, 65 surgical ICU survivors developed PICS within six months, with an incidence rate of 78.3%. The prevalences were 55.4% and 27.7% at the end of 3 and 6 months after ICU discharge, respectively. Univariate analysis showed that there was a correlation between the occurrence of PICS and the total bilirubin and creatinine levels at ICU admission, APACHE II score, ICU length of stay, and the presence of dialysis (P < 0.05). ICU length of stay was identified as an independent risk factor for the occurrence of PICS in surgical ICU survivors after adjusting for confounders.ConclusionThe overall PICS incidence in surgical ICU survivors was 78.3%, with prevalence gradually decreasing over time to 27.7% within 6 months. For surgical survivors requiring ICU care, the longer the ICU stay, the more likely to develop PICS.Implications for clinical practiceThe findings offer valuable insights into the incidence and risk factors of PICS in surgical ICU survivors, which can help healthcare professionals identify surgical cases at high risk of developing PICS and tailor the treatment effectively.

Comprehensive assessment and progression of health status during neurorehabilitation in survivors of critical illness: a prospective cohort study

BackgroundCritical illness survivors frequently suffer from long-term impairments, often described as post-intensive care syndrome (PICS). PICS encompasses physical, cognitive, and mental impairments. Additionally, the term intensive care unit (ICU)-acquired weakness (ICUAW) was coined for muscle weakness after critical illness. Research on the progression and outcome of individuals affected by PICS and ICUAW is scant. Thus we aimed to assess the health status and its progression during neurorehabilitation in critically ill patients using comprehensive outcome measures, describe the prevalence of PICS, and evaluate factors associated with rehabilitation outcomes.MethodsPatients with mixed reasons for critical illness who received ≥ 5 days of mechanical ventilation on the ICU and who were admitted to neurorehabilitation, were eligible to be included in this prospective cohort study. A number of outcomes (patient-reported, clinician-reported, and performance) were assessed after discharge from the ICU (V1) and shortly before discharge from inpatient neurorehabilitation (V2). The prevalence of PICS, defined as having at least one impairment in any PICS dimension), was calculated at V1 and V2. Multiple logistic regressions were conducted to identify factors associated with rehabilitation outcome (poor outcome = modified Rankin Scale > 2) and ICUAW at V2 (MRC sum score < 48).ResultsIn total, 250 critical illness survivors (62 ± 14 years, 34% female, median stay on ICU 55 days, median inpatient rehabilitation 65 days) were included. 11 participants (4.4%) died before V2. All outcomes improved significantly during rehabilitation except sensory impairment and pain. PICS was present in 96% at V1 and in 85% at V2, whereby mainly the physical domain (V1: 87%, V2: 66%; ICUAW with MRC sum score < 48) and the cognitive domain (V1:65%, V2:55%; Montreal Cognitive Assessment < 26) were affected. Mental impairment was lower (V1:48%, V2:29%; Hospital Anxiety and Depression Scale > 7), but still affected a considerable number of participants. Accordingly, health-related quality of life was rather low at discharge (0.64 ± 0.28, index value of EQ-5D-5L). MRC sum score at V1, duration of mechanical ventilation, and female gender were significantly associated with a poor rehabilitation outcome. Grip strength in % of reference at V1, age, female gender, and comorbidities were significantly associated with persistent ICUAW at discharge.ConclusionsDespite significant improvements during rehabilitation, survivors after critical illness experience a substantial burden of PICS and ICUAW at discharge from rehabilitation care. Survivors of critical illness require long-term follow-up, supportive structures, and tailored long-term multi-disciplinary therapies even after intensive rehabilitation.Trial registration: German Clinical Trials Register, DRKS00021753.

Performance of the Healthy Aging Brain Care Monitor Self Report in Monitoring Post-Intensive Care Syndrome Among Acute Respiratory Failure Survivors.

To describe the performance of the Healthy Aging Brain Care Monitor Self Report (HABC-M SR) in assessment of post-intensive care syndrome (PICS) among Acute Respiratory Failure ICU survivors. Secondary data analysis of a randomized controlled trial. Patients evaluated by a nurse care coordinator in an out-of-hospital setting. English-speaking adults 18 years old or older who were admitted to the ICU with acute respiratory failure requiring invasive or noninvasive mechanical ventilation for greater than or equal to 24 hours. Patients randomized to the intervention arm of the mobile critical care recovery program, a negative trial testing multidisciplinary care to improve quality of life. HABC-M SR scale was used to assess PICS in the intervention group at ICU discharge, 3, and 6 months post-discharge. Hospital Anxiety and Depression Scale; Pain, Enjoyment of Life, and General Activity Scale; Timed Up and Go; and Patient-Reported Outcomes Measurement Information System sleep scores were obtained at the same time. Mini-Mental State Examination (MMSE) was administered at baseline and 6 months. ICU survivors reported mild PICS symptoms, which improved over 6 months (mean HABC-M SR scores: baseline [8.5, sd 7.6], 3 mo [5.3 mo, sd 6.6 mo], and 6 mo [5.2 mo, sd 6.9 mo; p < 0.001]). HABC-M SR total score had moderate internal consistency that improved over time (Cronbach's alpha = 0.78 at baseline and 0.84 at 6 mo). The psychological subscale of HABC-M SR was moderately correlated with standardized scales for mood, pain, and sleep. The cognitive subscale was not significantly correlated with MMSE. While HABC-M SR correlated with mood, physical, and sleep symptoms, the cognitive subscale was less sensitive compared with standardized scales.

Incidence of post-intensive care syndrome among patients admitted to post-ICU multidisciplinary consultations: the retrospective observational PICS-MIR study

To determine the prevalence of functional, respiratory and renal impairments and of post-intensive-care-syndrome (PICS) among patients who had attended a post-ICU multidisciplinary consultation (post-ICU-MC) around 3 months after ICU discharge, we performed a retrospective, monocentric observational study, at Clermont Ferrand University hospital, France. We included patients who had attended a post-ICU-MC. Their characteristics during ICU stay and at the post-ICU-MC were collected. Functional status was assessed by the 6-min-walking test, handgrip test and peak inspiratory pressure, respiratory function by exploratory functional outcomes, mental status by SF-36 score, and quality of life by SF-36 score and European Quality of Life 5 Dimensions questionnaire. Overall, we enrolled 67 patients, of whom 70%, 74%, and 68% had functional, respiratory, and renal impairments, respectively, at the post-ICU-MC. Additionally, 40%, 28%, 19%, and 2.5% had three, two, one, and none of these impairments, respectively. All patients experienced mental disorders and a decline in quality of life. Functional impairment correlated with frailty score and sex, and respiratory function with age. To conclude, the prevalence of PICS in our cohort was high, as was that of functional, respiratory and renal failure.

Impact of Nutritional Therapy during Intensive Care Unit Admission on Post-Intensive Care Syndrome in Patients with COVID-19

Introduction: Nutritional therapy is an important component of intensive care. We investigated the associations of nutritional therapy in the acute phase of severe COVID-19 with the long-term outcomes of post-intensive care syndrome (PICS) and post-COVID-19 conditions. Methods: A questionnaire on the health status after COVID-19 was sent to patients 1 year after infection and PICS was evaluated. Total energy and protein intakes during the first week after admission to the intensive care unit (ICU) were calculated. The primary endpoint was a decrease in quality of life (QOL) defined by EuroQol5-dimensions 5-level (EQ5D5L) <0.8. A multivariable regression analysis was used to examine. Results: A total of 220 ICU patients were included in this study. Median total energy and protein intakes were 65.1 kcal/kg/week and 3.3 g/kg/week, respectively. Total energy and protein intakes were associated with EQ5D5L scores (energy: unit odds ratio 0.98 [0.97–0.99], p value <0.01; protein: unit odds ratio 0.72 [0.59–0.87], p value <0.01). Insufficient total energy and protein intakes were associated with malaise, arthralgia, myalgia, palpitations, sleep disturbance, and muscle weakness. Conclusions: Poor nutrition during the first week after ICU admission was associated with a decreased QOL 1 year after. These nutrition shortages were also associated with an increased risk of developing PICS, post-COVID-19 conditions, which may contribute to decreased QOL.

Long-term mental health impairments in survivors of critical illness

Abstract Background Survivors of critical illness frequently suffer from long-term disabilities, including physical, cognitive, and mental impairments (post-intensive care syndrome). However, long-term studies are scarce and healthcare services for critical illness survivors are limited, not only in Germany. Therefore, we followed-up on anxiety, depression, and post-traumatic stress disorder (PTSD) during post-intensive care unit (ICU) rehabilitation and up to 1 year after critical illness onset. Methods Patients at Schoen Clinic Bad Aibling in Germany were eligible for this prospective cohort study after receiving ≥5 days of mechanical ventilation. The Hospital Anxiety and Depression Scale (HADS; subcategory score ≥8) was conducted after ICU discharge (V1), at discharge from inpatient rehabilitation (V2) and 1 year after critical illness onset (V3). The Impact of Event Scale-6 (score ≥1.75) was conducted to assess PTSD at V3. Multiple logistic regressions were performed. Results We included 250 patients (62±14 years, 34% female, median stay on ICU 55 days, median duration of rehabilitation 65 days). 10% died before V3. Anxiety decreased during rehabilitation (effect size r = 0.35, p&amp;lt;.001), but increased again until V3 (r = 0.42, p&amp;lt;.001). At V3, 54% suffered from anxiety. Depression also decreased during rehabilitation (r = 0.46, p&amp;lt;.001), and increased again until V3 (r = 0.39, p&amp;lt;.001). At V3, 44% showed depressive symptoms and 38% suffered from PTSD. COVID-19 diagnosis was associated with increased anxiety (p&amp;lt;.001), depression (p=.068), and PTSD at V3 (p=.028), compared to non-COVID-19 patients. Furthermore, longer duration of mechanical ventilation was associated with increased anxiety (p=.041) and depression (p=.019) at V3. Conclusions Mental health impairments frequently occur in critical illness survivors, and they seem to worsen after rehabilitation. As these impairments can significantly impact daily functioning and quality of life, tailored healthcare services are urgently needed. Key messages • Anxiety, depression, and PTSD are frequent in critical illness survivors, even 1 year after critical disease onset. This calls for tailored healthcare services. • Patients with COVID-19 and longer mechanical ventilation suffer from more severe mental health impairments.

Associations Between Physical, Cognitive, and Mental Health Domains of Post-Intensive Care Syndrome and Quality of Life: A Longitudinal Multicenter Cohort Study.

To explore associations between the physical, cognitive, and mental post-intensive care syndrome (PICS) health domains with changes in health-related quality of life (HRQoL) following ICU admission. A longitudinal prospective multicenter cohort study. Patients (n = 4092) from seven Dutch ICUs. None. At ICU admission, 3 and 12 months post-ICU, patients completed validated questionnaires regarding physical health problems, cognitive health problems, mental health problems, and HRQoL. Composite scores were created for the physical health domain (physical problems and fatigue) and mental health domain (anxiety, depression, and post-traumatic stress disorder). Adjusted multivariable linear regression analyses were performed, including covariables (e.g., patient characteristics, disease severity, pre-ICU HRQoL, etc.) to explore associations between the physical, cognitive, and mental health domains of PICS and changes in HRQoL at 3 and 12 months post-ICU. At 3 months (n = 3368), physical health problems (β = -0.04 [95% CI, -0.06 to 0.02]; p < 0.001), cognitive health problems (β = -0.05 [95% CI, -0.09 to -0.02]; p < 0.001), and mental health problems (β = -0.08 [95% CI, -0.10 to -0.05]; p < 0.001) were negatively associated with changes in HRQoL. Also, at 12 months (n = 2950), physical health problems (β = -0.06 [95% CI, -0.08 to -0.03]; p < 0.001), cognitive health problems (β = -0.04 [95% CI, -0.08 to -0.01]; p < 0.015), and mental health problems (β = -0.06 [95% CI, -0.08 to -0.03]; p < 0.001) were negatively associated with changes in HRQoL. PICS symptoms in the physical, cognitive, and mental domains are all negatively associated with changes in HRQoL at 3 and 12 months post-ICU. At 3 months, PICS symptoms in the mental domain seem to have the largest negative associations. At 12 months, the associations of PICS in the mental and physical domains are the same. This implies that daily ICU care and follow-up care should focus on preventing and mitigating health problems across all three PICS domains to prevent a decrease in HRQoL.

Cognitive recovery of post critical care patients with and without COVID-19: differences and similarities, an observational study

BackgroundCoronavirus disease (COVID-19) patients treated in an intensive care unit (ICU) are at high risk of developing cognitive impairments of a “post-intensive care syndrome” (PICS). We explored whether critically ill COVID-19 and non-COVID-19 survivors differ in their post-ICU recovery course in terms of severity and affected cognitive domains.MethodsAn observational prospective study was conducted in a German post-acute neurological early rehabilitation clinic. Critically ill patients with or without SARS-CoV-2 infection (at least mechanically ventilated for one week) underwent repeated standardized assessments during their subsequent inpatient rehabilitation stay. Cognitive functions (information processing speed, learning, recognition, short-term and working-memory, word fluency, flexibility) assigned to different domains (attention, memory, executive functions) were assessed as primary outcome. Secondary outcomes included mental (depression, anxiety) and physical (Barthel index, modified ranking scale) state.ResultsOut of 92 eligible patients (screened between June 2021 and August 2023), 34 were examined, and 30 were available for analysis (15 per group). Both groups were ventilated for a similar period (COVID-19 vs. Non-COVID-19: median: 48 vs. 53 days). Patients of COVID-19 group spend on average 10 days longer at ICU and developed slightly more complications, but subsequent inpatient rehabilitation was of comparable duration (median: 36.5 vs. 37 days). On the group-level both groups showed similar cognitive dysfunctions with striking impairments (normative T-scores < 41) in information processing speed, word fluency, flexibility, and recognition memory on admission. Significant gains until discharge were only revealed for information processing speed in both groups (main effect visit, mean difference [95%CI] − 7.5 [− 13.1, − 2.0]). Physical and mental state were also similarly affected in both groups on admission, but improved over time, indicating that overall recovery for higher-order cognitive functions is slowest. Interestingly, majority of patients stated correctly being still physically disabled, while a discrepancy was found between subjective and objective evaluation of cognitive health.ConclusionsResults suggest a substantial overlap of cognitive, mental and physical dysfunction in post-acute recovery of ICU survivors independent of SARS-CoV-2 infection which warrants further monitoring to reduce the risk of long-term burden and enable a return to previous functionality.Trial registrationRetrospectively registered at https://drks.de/search/de/trial/DRKS00025523, 21.06.2021.

Patient follow-up after discharge from the paediatric intensive care unit: A scoping review.

Most children admitted to a paediatric intensive care unit (PICU) now survive because of improvements in care. Many studies have identified the psychological, functional, cognitive and social impact of PICU admission on a child and their family. However, expert recommendations on follow-up are lacking. To identify the strategies of clinical follow-up after PICU discharge performed from 2001 to 2021. This scoping review was undertaken between January and April 2021 using three databases: PubMed, EMBASE and CINAHL. The search strategy consisted of a combination of keywords, including PICU, post-PICU discharge and follow-up in articles published between 2001 and 2021. The results are reported according to PRISMA-ScR guidelines. Six-hundred and fifty-two articles were identified and 68 were analysed. Median age was 4.5 years and the two main reasons for PICU admission were cardiorespiratory failure and sepsis. Median length of PICU stay was 8 days. Most follow-up was carried out by research units (88%), while 6% of studies reported follow-up by a multidisciplinary PICU team. The most common follow-up schedule included an assessment at PICU discharge, and then at 3, 6 and 12 months. Follow-up for >1 year was reported in 20% of studies. One third of studies focused on follow-up quality of life and neurological outcomes. Parental emotional impact was assessed in 7% of studies. Follow-up after PICU discharge was highly heterogeneous regarding timing, health care professionals involved and assessment methods. There is an urgent need for standardization and coordination of PICU follow-up because of the increasing number of patients impacted by a PICU stay. Although most patients admitted to a paediatric intensive care unit (PICU) now survive; they may develop paediatric post-intensive care syndrome (PICS-P). To our knowledge, there are currently no clinical guidelines regarding follow-up after PICU discharge. This review summarizes current approaches to follow-up after PICU discharge, including how it is carried out, who is involved and what the main aims of assessment are.

Post-COVID-19 condition-Clinical phenotyping in practice

The high number and clinical heterogeneity of neurological impairments in patients with apost-COVID-19 condition (PCC) poses achallenge for outpatient care. Our aim was to evaluate the applicability of the proposed subtypes according to the guidelines "Long/Post-COVID" (30 May 2024) and their phenotyping using clinical and neuropsychological findings from our post-COVID outpatient clinic. The evaluation was based on cross-sectional neurological and psychological test examinations of the patients, which were carried out using standardized questionnaires and test batteries. In addition, adetailed anamnesis of the current symptoms and aretrospective survey of the acute symptoms up to 4 weeks after the confirmed infection was conducted. The subtypes were classified according to the abovementioned guidelines based on the medical history and selected patient questionnaires, to which we added a5th subtype with reference to the previous guidelines "Long/Post-COVID" (as of 5 March 2023). Atotal of 157 patients were included between August 2020 and March 2022. The presentation was at a median of 9.4months (interquartile range, IQR = 5.3) after infection, with amean age of 49.9 years (IQR = 17.2) and more women (68%) presenting, with atotal hospitalization rate of 26%. Subtype1 (postintensive care syndrome) showed the highest proportion of men, highest body mass index (BMI) scores and the highest rates of subjective complaints of word-finding difficulties (70%). Subtype2 (secondary diseases) was dominated by cognitive impairment and had the highest depression scores. Subtype3 (fatigue and exercise-induced insufficiency) was the most common, had the most symptoms and most severe subjective fatigue and the largest proportion of women. Subtype4 (exacerbation) mainly showed affective symptoms. Subtype5 (complaints without relevance to everyday life) had the lowest scores for depression, fatigue and BMI. Neurological and psychological conditions were frequently pre-existing in all groups. The management of PCC can be improved at various levels. Astandardized subtype classification enables early individually tailored treatment concepts. Patients at risk should be identified at the primary care level and informed about risk factors and prevention strategies. Regular monitoring of cardiovascular risk factors and physical activity are essential for PCC treatment. In the case of cognitive deficits and concurrent affective symptoms, psychotherapeutic support and drug treatment with selective serotonin reuptake inhibitors (SSRI) should be provided at an early stage.

Post-Intensive Care Syndrome as a Burden for Patients and Their Caregivers: A Narrative Review.

Millions of critically ill patients are discharged from intensive care units (ICUs) every year. These ICU survivors may suffer from a condition known as post-intensive care syndrome (PICS) which includes a wide range of cognitive, psychological, and physical impairments. This article will provide an extensive review of PICS. ICU survivors may experience cognitive deficits in memory and attention, with a slow-down of mental processing and problem-solving. From psychological perspectives, depression, anxiety, and post-traumatic stress disorder are the most common issues suffered after ICU discharge. These psycho-cognitive impairments might be coupled with ICU-acquired weakness (polyneuropathy and/or myopathy), further reducing the quality of life, the ability to return to work, and other daily activities. The burden of ICU survivors extends to families too, leading to the so-called PICS-family (or PICS-F), which entails the psychological impairments suffered by the family and, in particular, by the caregiver of the ICU survivor. The development of PICS (and PICS-F) is likely multifactorial, and both patient- and ICU-related factors may influence it. Whilst the prevention of PICS is complex, it is important to identify the patients at higher risk of PICS, and clinicians should be aware of the tools available for diagnosis. Stakeholders should implement strategies to achieve PICS prevention and to support its effective treatment during the recovery phase with dedicated pathways and supporting care.
