Exploring adult critical illness survivors' experiences of fatigue: A qualitative study

The nutritional characteristics and experiences of survivors of critical illness after hospital discharge: A multi-method narrative review

BACKGROUND & AIMS

Many survivors of critical illness experience long-term functional, cognitive, and psychological impairments known as post-intensive care syndrome (PICS). Yet, the nutritional recovery experiences of intensive care unit (ICU) survivors after hospital discharge remain underrecognized and poorly understood. The objective of this review was to characterize nutritional indices and nutrition-related outcomes in survivors of critical illness, and to understand the nutritional recovery experience after hospital discharge.

METHODS

Searches were conducted for eligible quantitative and qualitative studies between June and August 2024 using PubMed, CINAHL Complete, and Scopus electronic databases. Abstracts and full texts were screened against predetermined inclusion and exclusion criteria. Primary research analyzing anthropometric, nutritional, and/or experiential data of adult survivors of critical illness after hospital discharge were included in this review.

RESULTS

21 quantitative (n = 3054) and 7 qualitative (n = 162) studies were included. After hospital discharge, ICU survivors seldom returned to their baseline weight with many having small to modest weight gains in the first months of recovery. Average calorie (18-33.5 calories/kilogram/day) and protein (0.96-1.6 g/kg/day) intakes largely did not meet requirements needed to facilitate recovery, resulting in high rates of malnutrition, ranging from 16.8 to 63 % 3 months after discharge. A multitude of barriers to nutritional recovery were faced in the post-discharge period resulting from persistent physical and functional limitations due to critical illness. Ongoing individualized nutrition monitoring and follow-up from dietetic professionals knowledgeable in post-ICU care has the potential to improve nutrition-related outcomes for survivors yet remains underutilized. Improving the availability and affordability of such services is a key facilitator to improve the nutritional recovery experience for ICU survivors.

CONCLUSIONS

After hospital discharge, many survivors of critical illness face numerous barriers to nutritional recovery resulting in long-term nutritional complications. Future research efforts should target nutritional characterization, associations between nutritional variables and PICS, and the identification and development of effective nutrition interventions to improve long-term outcomes for survivors of critical illness after hospital discharge.

Prevalence of Fatigue, Risk Factors, and Relationship With Self-Rated Health Six Months After ICU Discharge in Japan: An Ambidirectional Cohort Study

Background Fatigue presents an important challenge for patients discharged from intensive care units (ICUs). Despite its importance, data on the prevalence and clinical impact of post-ICU fatigue remain limited. In particular, the proportion of patients in clinical settings in Japan who find fatigue distressing, as well as the associations between fatigue, risk factors, and self-rated health, have not been fully explored using validated fatigue measures. Therefore, this study aimed to assess the prevalence of fatigue, identify its associated risk factors, and examine the relationship between fatigue and self-rated health status six months after ICU discharge in Japan. Methods This single-center, ambidirectional cohort study administered a survey to patients aged ≥18 years, six months after ICU discharge, to assess fatigue and self-rated health. Retrospective data were also collected from patients' medical records during hospitalization. Fatigue prevalence was the primary endpoint, measured using the cutoff value of the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) scale. Logistic regression analysis was performed to identify risk factors for fatigue. Locally weighted scatterplot smoothing (LOWESS) plots were generated with FACIT-F scale scores, and the association between fatigue and EuroQol 5 Dimensions 5-Level Visual Analog Scale (EQ-VAS) was analyzed. Results Questionnaires were sent to 87 patients, of whom 81 (93.1%) responded. Eight patients (9.9%) with missing FACIT-F scores were excluded, leaving 73 patients for analysis. The median (interquartile range) age of eligible patients was 74 (63-81) years, and 33 patients (45%) were male. Forty-six patients (63%) reported fatigue. Multivariate analysis identified a higher body mass index (BMI) at ICU admission as an independent risk factor for fatigue (odds ratio (OR) = 1.195; 95% confidence interval (CI) 1.018-1.447; p < 0.05). EQ-VAS scores were significantly lower in the fatigue group (OR 72.5, 95% CI 60-83.8 vs. OR 90, 95% CI 80-90; p < 0.01). Conclusion This study found that many patients in Japanese ICUs experience fatigue, even when disease severity is low. Additionally, BMI at ICU admission was identified as an independent risk factor for fatigue six months after ICU discharge. Regular follow-up on fatigue after ICU discharge is essential for improving long-term outcomes.

The interactivity and independence of Recovery challenges and coping strategies for ICU survivors and their caregivers: a systematic review and Meta-synthesis

BACKGROUND

The post-ICU home recovery period requires patients and caregivers to confront recovery challenges and adopt coping strategies as a family dyad, necessitating effective dyadic interaction patterns. Existing qualitative research shows that the dyads face interactive or independent challenges and employs varying coping strategies, which may include strong communication or, conversely, avoidance. However, a single qualitative study alone might offer limited generalizability, and there is a lack of broader, more nuanced understanding about the recovery challenge and copings among ICU survivors and caregivers. This meta-synthesis aims to figure out the interactivity and independence of challenges and coping strategies during the recovery process for ICU survivors and caregivers.

METHODS

This is a meta-synthesis of qualitative studies, which was guided by the Stress and Coping Framework. We systematically reviewed six electronic databases, including PubMed, Medline, the Cochrane Library, CINAHL, PsycArticles, and PsycInfo, for relevant qualitative studies published from inception to January, 2024. We utilized a content analysis approach for data analysis. Presentation of this synthesis adhered to the PRISMA guideline and the ENTREQ guideline.

RESULTS

After full-text screening, 49 studies were included. Four themes with 16 sub-themes emerged from this synthesis including, interactivity of recovery challenges for ICU survivors and caregivers (subthemes: Life was turned upside down, Situational overstrain, Isolation without compassion, Empowerment conflicts, Marginalized support), independence of recovery challenges for ICU survivors and caregivers (subthemes: Recovery means silent suffering, Gap in memory, Sacrificing to caregiving), interactivity of recovery coping strategies for ICU survivors and caregivers (subthemes: Reorientation of mindset, Cultivating inner power, Sharing burden with an open-ear, Going through thick and thin together, Negotiating care level), and independence of recovery coping strategies for ICU survivors and caregivers (subthemes: Wearing a faked smile, Developing daily routine, Seeking respite).

CONCLUSIONS

The findings suggest that ICU survivors and caregivers experience overlapping yet distinct challenges during recovery, often involving shared coping strategies, alongside a need for individual space. These results support the presence of both interactivity and independence in recovery challenges and coping strategies for ICU survivors and their caregivers. Therefore, we call for future dyadic or family interventions to target both ICU survivors and caregivers, taking advantage of their interactivity and desire for gradual independence, so that fostered individualized coping strategies adapted to flexible contexts.

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.

Patients' perspectives of recovery after COVID-19 critical illness: An interview study

BACKGROUND

Critical illness is a traumatic experience, often resulting in post-intensive care syndrome, affecting people's physical, psychological, emotional, and social well-being. The early recovery period is associated with increased risk, negatively impacting longer-term outcomes.

AIMS

The aims of this study were to understand the recovery and rehabilitation needs of people who survive a COVID-19 critical illness.

STUDY DESIGN

An exploratory descriptive qualitative interview study with 20 survivors of COVID-19 critical illness from two community-based healthcare settings in London, England. Data collection took place September 2020-April 2021, at least 1 month after hospital discharge by telephone or virtual platform. Data were subjected to inductive thematic analysis and mapped deductively to the three core concepts of self-determination theory: autonomy, competence and relatedness.

RESULTS

Three key themes emerged: traumatic experience, human connection and navigating a complex system. Participants described how societal restrictions, fear and communication problems caused by the pandemic added to their trauma and the challenge of recovery. The importance of positive human connections, timely information and support to navigate the system was emphasized.

CONCLUSIONS

Whilst findings to some extent mirror those of other qualitative pre-pandemic studies, our findings highlight how the uncertainty and instability caused by the pandemic add to the challenge of recovery affecting all core concepts of self-determination (autonomy, competence, relatedness).

RELEVANCE TO CLINICAL PRACTICE

Understanding survivors' perspectives of rehabilitation needs following COVID-19 critical illness is vital to delivery of safe, high-quality care. To optimize chances of effective recovery, survivors desire a specialist, co-ordinated and personalized recovery pathway, which reflects humanized care. This should be considered when planning future service provisions.

Non-pharmacological interventions for self-management of fatigue in adults: An umbrella review of potential interventions to support patients recovering from critical illness

PURPOSE

Fatigue is a common symptom after critical illness. However, evidence-based interventions for fatigue after critical illness are lacking. We aimed to identify interventions to support self-management of fatigue caused by physical conditions and assess their effectiveness and suitability for adaptation for those with fatigue after critical illness.

MATERIALS AND METHODS

We conducted an umbrella review of systematic reviews. Databases included CINAHL, PubMed, Medline, PsycINFO, British Nursing Index (BNI), Web of Science, Cochrane Database of Systematic Reviews (CDSR), JBI Evidence Synthesis Database, and PROSPERO register. Included reviews were appraised using the JBI Checklist for Systematic Reviews and Research Syntheses. Results were summarised narratively.

RESULTS

Of the 672 abstracts identified, 10 met the inclusion criteria. Reviews focused on cancer (n = 8), post-viral fatigue (n = 1), and Systemic Lupus Erythematosus (SLE) (n = 1). Primary studies often did not address core elements of self-management. Positive outcomes were reported across all reviews, and interventions involving facilitator support appeared to be most effective.

CONCLUSIONS

Self-management can be effective at reducing fatigue symptoms and improving quality of life for physical conditions and has clear potential for supporting people with fatigue after critical illness, but more conclusive data on effectiveness and clearer definitions of self-management are required.
