Prevalence of self-reported fatigue in intensive care unit survivors 6 months-5 years after discharge

Post-Intensive Care Syndrome: Physical Impairments and Function

Patients surviving critical illness are at risk of persistent physical impairments related to Post Intensive Care Syndrome. Physical impairments and symptoms have potential for recovery, but frequently impact quality of life, performance of activities of daily living and participation in societal roles. Patient and illness-related risk factors directly relate and may predict physical functional outcomes providing opportunity for clinicians and scientist to develop targeted intervention strategies. Clinicians and scientists should screen and assess physical impairments and symptoms early following Intensive care unit discharge with a serial approach to promote for targeted and individualized treatment.

Effect size estimates of risk factors for post-intensive care syndrome: A systematic review and meta-analysis

OBJECTIVE

To provide updated evidence on the risk factors and accurately quantify the effect size of the risk factors associated with post-intensive care syndrome (PICS), encompassing cognitive, mental, physical and socio-economic domains.

RESEARCH METHODOLOGY

We conducted a systematic review of literature from January 2010 to October 2023. The meta-analysis was conducted to calculate an effect size for every risk factor, and odds ratio and 95% confidence intervals were used as summary statistics.

RESULTS

Of 67,468 retrieved studies, 160 were included in qualitative synthesis, 102 were included in quantitative synthesis. A total of 60 factors were identified, categorized into 17 person-related, 23 disease-related and 20 ICU-related categories. The strongest correlations with cognitive health were observed for previous cognitive problems, sedatives and delirium. Factors most strongly correlated with mental health included previous mental problems, delirium, lack of social support, illicit drug and bad experience in ICU. The strongest correlations with physical health involved previous mental problem, delirium, organ dysfunction of neurologic and respiratory support. For socio-economic domains, older age and female were identified as significant risk factors.

CONCLUSIONS

This systematic review and meta-analysis identified and quantified the person, disease, and ICU-related risk factors associated with PICS. These findings may enable clinicians to better recognize the patient at high risk for PICS at an early stage during their stay in ICU.

IMPLICATIONS FOR CLINICAL PRACTICE

A thorough investigation of risk factors across the four domains of PICS is necessary to gain a holistic understanding. The identification and integration of risk factors associated with PICS empower critical care multidisciplinary teams to optimize management strategies, thereby assisting ICU survivors a better recovery. Since multiple risk factors may be simultaneously associated with the four domains of post-intensive care syndrome, it is imperative to develop a comprehensive prediction algorithm.

Factors Associated with Fatigue in COVID-19 ICU Survivors

PURPOSE

Approximately 30% of people infected with COVID-19 require hospitalization, and 20% of them are admitted to an intensive care unit (ICU). Most of these patients experience symptoms of fatigue weeks post-ICU, so understanding the factors associated with fatigue in this population is crucial.

METHODS

Fifty-nine patients (38-78 yr) hospitalized in ICU for COVID-19 infection for 32 (6-80) d, including 23 (3-57) d of mechanical ventilation, visited the laboratory on two separate occasions. The first visit occurred 52 ± 15 d after discharge and was dedicated to questionnaires, blood sampling, and cardiopulmonary exercise testing, whereas measurements of the knee extensors neuromuscular function and performance fatigability were performed in the second visit 7 ± 2 d later.

RESULTS

Using the FACIT-F questionnaire, 56% of patients were classified as fatigued. Fatigued patients had worse lung function score than non-fatigued (i.e., 2.9 ± 0.8 L vs 3.6 ± 0.8 L; 2.4 ± 0.7 L vs 3.0 ± 0.7 L for forced vital capacity and forced expiratory volume in 1 s, respectively), and forced vital capacity was identified as a predictor of being fatigued. Maximal voluntary activation was lower in fatigued patients than non-fatigued patients (82% ± 14% vs 91% ± 3%) and was the only neuromuscular variable that discriminated between fatigued and non-fatigued patients. Patient-reported outcomes also showed differences between fatigued and non-fatigued patients for sleep, physical activity, depression, and quality of life ( P < 0.05).

CONCLUSIONS

COVID-19 survivors showed altered respiratory function 4 to 8 wk after discharge, which was further deteriorated in fatigued patients. Fatigue was also associated with lower voluntary activation and patient-reported impairments (i.e., sleep satisfaction, quality of life, or depressive state). The present study reinforces the importance of exercise intervention and rehabilitation to counteract cardiorespiratory and neuromuscular impairments of COVID-19 patients admitted in ICU, especially individuals experiencing fatigue.

Impact of COVID-19 critical illness on functional status, fatigue symptoms, and health-related quality of life one-year after hospital discharge: a systematic review and meta-analysis

PURPOSE

To estimate the prevalence and severity of impairments in functional status, fatigue, and health-related quality of life (HRQoL) among critical COVID-19 survivors one-year after hospital discharge.

METHODS

A systematic review was conducted following PRISMA statement and registered in PROSPERO (CRD42021258356), with searches in eight databases. Observational studies were selected. The prevalence meta-analysis of abnormalities was performed using random-effects models. Risk of bias was evaluated using the National Heart, Lung, and Blood Institute tool.

RESULTS

Twenty studies were included, with data collected between 12 and 13.5 months after hospital discharge and a total of 1828 participants. Of these, 71% were men, and 77.7% were intubated in the intensive care unit (ICU). Impairments and sequelae were identified in varying prevalence and degrees, with greater impact on functional capacity and physical components of fatigue and HRQoL. The prevalence of abnormalities of 32.3% [95% CI 23.9; 41.9] found in the meta-analysis is substantially high. Most studies were classified as having fair and poor quality.

CONCLUSION

Critical COVID-19 survivors experience impairments in functional status, fatigue, and HRQoL to varying degrees one-year after hospital discharge, particularly among patients who stayed in the ICU and on MV for a prolonged period.

Pulmonary Rehabilitation for People With Persistent Symptoms After COVID-19

TOPIC IMPORTANCE

COVID-19 can cause ongoing and persistent symptoms (such as breathlessness and fatigue) that lead to reduced functional capacity. There are parallels in symptoms and functional limitations in adults with post-COVID symptoms and adults with chronic respiratory diseases. Pulmonary rehabilitation is a key treatment for adults with chronic respiratory diseases, with the aims to improve symptom management and increase functional capacity. Given the similarities in presentation and aims, a pulmonary rehabilitation program may be optimal to meet the needs of those with ongoing symptoms after COVID-19.

REVIEW FINDINGS

Aerobic and strength training has shown benefit for adults living with long COVID, although there is little evidence on structured education in this population. Breathing pattern disorder is common in adults with long COVID, and considerations on treatment before rehabilitation, or alongside rehabilitation, are necessary. Considerations on postexertional malaise are important in this population, and evidence from the chronic fatigue syndrome literature supports the need for individualization of exercise programs, and considerations for those who have an adverse reaction to activity and/or exercise.

SUMMARY

This narrative review summarizes the current evidence on pulmonary rehabilitation programs in a long-COVID population. Where the evidence is lacking in long COVID the supporting evidence of these programs in chronic respiratory diseases has highlighted the importance of aerobic and strength training, considerations for fatigue, potential mechanisms for immunology improvement, and management of breathing pattern disorders in these programs.

Fatigue after CriTical illness (FACT): Co-production of a self-management intervention to support people with fatigue after critical illness

PURPOSE

Fatigue is a common and debilitating problem in patients recovering from critical illness. To address a lack of evidence-based interventions for people with fatigue after critical illness, we co-produced a self-management intervention based on self-regulation theory. This article reports the development and initial user testing of the co-produced intervention.

METHODS

We conducted three workshops with people experiencing fatigue after critical illness, family members, and healthcare professionals to develop a first draft of the FACT intervention, designed in web and electronic document formats. User testing and interviews were conducted with four people with fatigue after critical illness. Modifications were made based on the findings.

RESULTS

Participants found FACT acceptable and easy to use, and the content provided useful strategies to manage fatigue. The final draft intervention includes four key topics: (1) about fatigue which discusses the common characteristics of fatigue after critical illness; (2) managing your energy with the 5 Ps (priorities, pacing, planning, permission, position); (3) strategies for everyday life (covering physical activity; home life; leisure and relationships; work, study, and finances; thoughts and feelings; sleep and eating); and (4) goal setting and making plans. All material is presented as written text, videos, and supplementary infographics. FACT includes calls with a facilitator but can also be used independently.

CONCLUSIONS

FACT is a theory driven intervention co-produced by patient, carer and clinical stakeholders and is based on contemporary available evidence. Its development illustrates the benefits of stakeholder involvement to ensure interventions are informed by user needs. Further testing is needed to establish the feasibility and acceptability of FACT.

IMPLICATIONS FOR CLINICAL PRACTICE

The FACT intervention shows promise as a self-management tool for people with fatigue after critical illness. It has the potential to provide education and strategies to patients at the point of discharge and follow-up.

Reduced health-related quality of life, fatigue, anxiety and depression affect COVID-19 patients in the long-term after chronic critical illness

The term chronic critical illness describes patients suffering from persistent organ dysfunction and prolonged mechanical ventilation. In severe cases, COVID-19 led to chronic critical illness. As this population was hardly investigated, we evaluated the health-related quality of life, physical, and mental health of chronically critically ill COVID-19 patients. In this prospective cohort study, measurements were conducted on admission to and at discharge from inpatient neurorehabilitation and 3, 6, and 12 months after discharge. We included 97 patients (61 ± 12 years, 31% women) with chronic critical illness; all patients required mechanical ventilation. The median duration of ICU-treatment was 52 (interquartile range 36-71) days, the median duration of mechanical ventilation was 39 (22-55) days. Prevalences of fatigue, anxiety, and depression increased over time, especially between discharge and 3 months post-discharge and remained high until 12 months post-discharge. Accordingly, health-related quality of life was limited without noteworthy improvement (EQ-5D-5L: 0.63 ± 0.33). Overall, the burden of symptoms was high, even one year after discharge (fatigue 55%, anxiety 42%, depression 40%, problems with usual activities 77%, pain/discomfort 84%). Therefore, patients with chronic critical illness should receive attention regarding treatment after discharge with a special focus on mental well-being.Trial registration: German Clinical Trials Register, DRKS00025606.

Assessment and personalised advice for fatigue in systemic lupus erythematosus using an innovative digital tool: the Lupus Expert system for the Assessment of Fatigue (LEAF) study

BACKGROUND

Fatigue is reported as the most prevalent symptom by patients with systemic lupus erythematosus (SLE). Fatigue management is complex due to its multifactorial nature. The aim of the study was to assess the usefulness of an innovative digital tool to manage fatigue in SLE, in a completely automated manner.

METHODS

The «Lupus Expert System for Assessment of Fatigue» (LEAF) is free digital tool which measures the intensity and characteristics of fatigue and assesses disease activity, pain, insomnia, anxiety, depression, stress, fibromyalgia and physical activity using validated patient-reported instruments. Then, LEAF automatically provides personalised feedback and recommendations to cope with fatigue.

RESULTS

Between May and November 2022, 1250 participants with SLE were included (95.2% women, median age 43yo (IQR: 34-51)). Significant fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue <34) was reported by 78.9% of patients. In univariate analysis, SLE participants with fatigue were more likely to be women (p=0.01), perceived their disease as more active (p<0.0001), had higher levels of pain (p<0.0001), anxiety (p<0.0001), depression (p<0.0001), insomnia (p<0.0001), stress (p<0.0001) and were more likely to screen for fibromyalgia (p<0.0001), compared with patients without significant fatigue. In multivariable analysis, parameters independently associated with fatigue were insomnia (p=0.0003), pain (p=0.002), fibromyalgia (p=0.008), self-reported active SLE (p=0.02) and stress (p=0.045). 93.2% of the participants found LEAF helpful and 92.3% would recommend it to another patient with SLE.

CONCLUSION

Fatigue is commonly severe in SLE, and associated with insomnia, pain, fibromyalgia and active disease according to patients' perspective. Our study shows the usefulness of an automated digital tool to manage fatigue in SLE.

Changes in Restricting Symptoms after Critical Illness among Community-Living Older Adults

Rationale: Survivors of critical illness have multiple symptoms, but how restricting symptoms change after critical illness and whether these changes differ among vulnerable subgroups is unknown. Objectives: To evaluate changes in restricting symptoms over the six months after critical illness among older adults and to determine whether these changes differ by sex, multimorbidity, and individual- and neighborhood-level socioeconomic disadvantage. Methods: From a prospective longitudinal study of 754 community-living adults ⩾70 years old interviewed monthly (1998-2018), we identified 233 admissions from 193 participants to the ICU. The occurrence of 15 restricting symptoms, defined as those leading to restricted activity, were ascertained during interviews in the month before ICU admission (baseline) and each of the six months after hospital discharge. Measurements and Main Results: The occurrence and number of restricting symptoms increased more than threefold in the six months after a critical illness hospitalization (adjusted rate ratio [95% confidence interval], 3.1 [2.1-4.6] and 3.3 [2.1-5.3], respectively), relative to baseline. These increases were largest in the first month after hospitalization (adjusted rate ratio [95% confidence interval], 5.3 [3.8-7.3] and 5.4 [3.9-7.5], respectively] before declining and becoming nonsignificant in the third month. Increases in restricting symptoms did not differ significantly by sex, multimorbidity, or individual- or neighborhood-level socioeconomic disadvantage. Conclusions: Restricting symptoms increase substantially after a critical illness before returning to baseline three months after hospital discharge. Our findings highlight the need to incorporate symptom management into post-ICU care and for further investigation into whether addressing restricting symptoms can improve quality of life and functional recovery among older ICU survivors.

Examining the needs of survivors of critical illness through the lens of palliative care: A qualitative study of survivor experiences

OBJECTIVE

To examine the needs of adult survivors of critical illness through a lens of palliative care.

RESEARCH METHODOLOGY

A qualitative study of adult survivors of critical illness using semi-structured interviews and framework analysis.

SETTING

Participants were recruited from the post-intensive care unit clinic of a mid-Atlantic academic medical center in the United States.

FINDINGS

Seventeen survivors of critical illness aged 34-80 (median, 66) participated in the study. The majority of patients were female (64.7 %, n = 11) with a median length of index ICU stay of 12 days (interquartile range [IQR] 8-19). Interviews were conducted February to March 2021 and occurred a median of 20 months following the index intensive care stay (range, 13-33 months). We identified six key themes which align with palliative care principles: 1) persistent symptom burden; 2) critical illness as a life-altering experience; 3) spiritual changes and significance; 4) interpreting/managing the survivor experience; 5) feelings of loss and burden; and 6) social support needs.

CONCLUSION

Our findings suggest that palliative care components such as symptom management, goals of care discussions, care coordination, and spiritual and social support may assist in the assessment and treatment of survivors of critical illness.

Prevalence of fatigue and its explicative variables among people with multiple sclerosis

BACKGROUND: Fatigue is the most prevalent symptom among people with multiple sclerosis (PwMS). Although exercise effectively reduces fatigue, the relationship between daily physical activity and fatigue has only recently been demonstrated. OBJECTIVE: The aim of this study was to evaluate the prevalence of fatigue and to understand the relationship with several variables in French PwMS. METHODS: Data were collected from 191 PwMS using Modified Fatigue Impact Scale (MFIS) and Fatigue Severity Scale (FSS) for fatigue, and the Godin Leisure-Time Exercise Questionnaire (GLTEQ) for physical activity. RESULTS: 110 PwMS (57%), 35 PwMS (18%) and 46 PwMS (24%) were considered as fatigued, non-fatigued and in the grey zone, respectively. Greater physical activity was observed in non-fatigued PwMS (20.2±19.8) compared to fatigued PwMS (12.5±14.1). FSS and MFIS scores were associated with physical activity (r = –0.28 and r = –0.25, respectively, p <  0.05). Using multivariate analysis, disability, physical activity and being unemployed explained 21% of the variance of the MFIS. CONCLUSIONS: The present study confirms that physical activity and fatigue are associated. Disability and unemployment status should also to be consider when assessing fatigue. Activity-oriented health policies should be redesigned to improve fatigue among PwMS.
