Comparison of energy intake in critical illness survivors, general medical patients, and healthy volunteers: A descriptive cohort study

BACKGROUND

Intensive care unit (ICU) survivors have reduced oral intake; it is unknown whether intake and associated barriers are unique to this group.

OBJECTIVE

To quantify energy intake and potential barriers in ICU survivors compared with general medical (GM) patients and healthy volunteers.

DESIGN

A descriptive cohort study in ICU survivors, GM patients, and healthy volunteers. Following an overnight fast, participants consumed a 200 ml test-meal (213 kcal) and 180 min later an ad libitum meal to measure energy intake (primary outcome). Secondary outcomes; taste recognition, nutrition-impacting symptoms, malnutrition, and quality of life (QoL). Data are mean ± SD, median (interquartile range [IQR]) or number [percentage]).

RESULTS

Twelve ICU survivors (57 ± 17 years, BMI: 30 ± 6), eight GM patients (69 ± 19 years, BMI: 30 ± 6), and 25 healthy volunteers (58 ± 27 years, BMI: 25 ± 4) were included. Recruitment ceased early because of slow recruitment and SARS-CoV-2. Energy intake was lower in both patient groups than in health (ICU: 289 [288, 809], GM: 426 [336, 592], health: 815 [654, 1165] kcal). Loss of appetite was most common (ICU: 78%, GM: 67%). For ICU survivors, GM patients and healthy volunteers, respectively, severe malnutrition prevalence; 40%, 14%, and 0%; taste identification; 8.5 [7.0, 11.0], 8.5 [7.0, 9.5], and 8.0 [6.0, 11.0]; and QoL; 60 [40-65], 50 [31-55], and 90 [81-95] out of 100.

CONCLUSIONS

Energy intake at a buffet meal is lower in hospital patients than in healthy volunteers but similar between ICU survivors and GM patients. Appetite loss potentially contributes to reduced energy intake.

Physical activity and sedentary behavior in middle-aged intensive care unit survivors discharged home: A systematic review

OBJECTIVES

The purpose of this study was to review literature on physical activity and sedentary behavior of middle-aged adults post-discharge from the intensive care unit, with a particular focus on studies using wearable activity trackers.

METHODOLOGY

Systematic review conducted using correlational, cohort, and intervention studies of physical activity and sedentary behavior of intensive care unit survivors' post-discharge. Literature in PubMed, Embase, and CINAHL was searched using keywords derived from patient status, activity, and activity monitoring. Two independent reviewers used the National Institutes of Health Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies to assess quality of articles and potential biases in study design.

MAIN OUTCOME MEASURES

Physical activity and sedentary behavior assessed via wearable activity trackers.

RESULTS

Two hundred and fifty-six studies met inclusion criteria; six studies comprising 265 participants were retained. Outcomes varied widely and were not synthesized, but instead discussed individually. Average steps/day ranged from 1278 to 4958 and average minutes of activity ranged from 26 to 45 min/day. One study reported 12 hours and 17 min/day spent in sedentary activity and another reported 90 % of hospitalization was in sedentary behavior compared to 58 % post-discharge.

CONCLUSION

Few studies have examined physical activity and sedentary levels of middle-aged intensive care unit survivors wearing activity trackers. Findings are limited in generalizability, and no randomized controlled trials were included here. Eliciting support from clinical and post-discharge care teams to encourage activity and/or attend prescribed therapy or rehabilitation sessions is important.

IMPLICATIONS FOR CLINICAL PRACTICE

Clinicians should emphasize the importance of physical activity throughout the day to decrease sedentary time during a hospital stay and to continue being active after discharge to home. Physical activity is valuable, even in short spurts, from hospital stay through discharge. Interventions to increase physical activity and decrease sedentary time are needed to improve intensive care unit survivor recovery and quality of life post-discharge.

Barriers and facilitators to offering post-intensive care follow-up services from the perspective of critical care professionals: A qualitative study

BACKGROUND

Various programmes and models for post-intensive care unit (ICU) follow-up services have been developed worldwide. In China, post-ICU follow-up remains in the exploratory stage and little is known regarding the appropriate form and challenges of implementation, which need to be further explored.

AIM

This study aimed to explore and describe the barriers to and facilitators of post-ICU follow-up services from the perspective of critical care professionals.

DESIGN

This was a descriptive qualitative study. Semi-structured interviews were conducted with 21 health care workers whose units had offered ICU survivors different forms of follow-up services; the data were analysed by qualitative content analysis during August 2022 and December 2022.

SETTING

The study was conducted at 14 ICUs in 11 tertiary hospitals in Shanghai, China.

FINDINGS

Seventeen subthemes were extracted as barriers and facilitators in the follow-up of ICU survivors. In the initiating process, the barriers included the restriction of decision-making rights and scope of practice, indifferent attitude towards survivors and repeated work. The facilitators included admitted significance, the needs of ICU survivors, the conscientiousness of professionals and the pioneers and leadership support. In the implementation process, lack of confidence, lack of cooperation in medical consortium, distrusted relationships, restrictions of medical insurance, ageing problems and insufficient human resources acted as barriers, whereas lessons learned, positive feedback and digital support served as facilitators. Furthermore, recommendations and tips were identified for offering follow-up services.

CONCLUSION

Medical personnel can better utilize available resources and develop strategies to overcome constraints by gaining insights into the abovementioned barriers and facilitators. The findings of this study can provide a useful reference for structured and systematic follow-ups to ameliorate post-intensive care syndrome in low- and middle-income countries.

RELEVANCE TO CLINICAL PRACTICE

Publicity and educational measures play a crucial role in enhancing the awareness of survivors and the consensus of health care professionals from medical consortium regarding impairments after critical care. Leadership and policy support can address numerous obstacles to guiding follow-up services.

Assessment of health-related quality of life and its determinants among COVID-19 intensive care unit survivors

Background

Health-related quality of life (HRQoL) is a multidimensional concept encompassing the physical, functional, emotional, and social/family well-being of an individual. Recent reports suggest that Covid-19 may lead to poorer HRQoL of the patients infected both in the short and long term. The present study aimed to assess the health-related quality of life and their determinants among COVID-19 intensive care unit (ICU) survivors.

Materials and Methods

In the study, 107 COVID-19 (RTPCR positive) patients admitted to the (ICU) of a tertiary care centre from August 2021-January 2022 were taken from the hospital records. Line listing of all the patients was done, and the study population was selected using the lottery method under a simple random sampling method. The study population was contacted by telephone and requested their willingness to participate in the study. EQ-5D-5L was used to assess quality of life, which is a standard instrument to assess HRQoL (developed by the EuroQol group in 2011). The EQ-5D-5L essentially consists of the EQ-5D descriptive system and the EQ visual analogue scale (EQ-VAS). Data entry was done using Microsoft excel 2019 version and data analysis using MedCalc version 20.015.

Results

The mean EQ-5D-5L utility score was 0.51 ± 0.43. The mean EQ-VAS score was 68.97 ± 22.27. A significant association between co-morbidities and EQ-5D-5L utility score where those with co-morbidities had a lesser EQ-5D-5L score compared to those without co-morbidities. The mean duration of ICU stay in days was 12.29 ± 12.17. A significant negative correlation between the duration of ICU stay and EQ-5D-5L. (r = -0.26, P = 0.0006*).

Conclusion

COVID-19 patients with comorbidities had a significantly poor quality of life. These findings may help healthcare professionals and decision-makers to better understand the consequences of COVID-19 on the HRQoL.

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.

The Intensive Care Unit diary - A significant complement in the recovery after intensive care. A focus group study

OBJECTIVES

The aim of this study was to gain an increased understanding of the intensive care unit diary and how it affects patients' recovery after intensive care.

METHODOLOGY/DESIGN

The study had a qualitative design and was conducted by two focus group interviews in October 2021 and was analysed with thematic analysis.

SETTING

Ventilator treated intensive care patients with a length of stay ≥ 72 hours who had received a written diary were included. The study was conducted at two university hospitals in the south of Sweden.

FINDINGS

The intensive care unit diary can be an important complement to the medical record and notes taken by family members by enhancing understanding of critical illness. The patients experience several prominent feelings from reading the diary such as guilt, fear, and anxiety as well as feelings of being cared for. The design and content of the diary can be important used as a tool in patients' recovery after intensive care.

CONCLUSION

Understanding their critical illness and the time in intensive care seems important to former intensive care patients. In this respect, the intensive care unit diary on its own does not provide significant information and thus need to be complemented by information from the medical record and notes taken by family members. Therefore, the diary can be used as a complement that might increase patients' sense of coherence and facilitate recovery after intensive care.

Evolution in Care Delivery within Critical Illness Recovery Programs during the COVID-19 Pandemic: A Qualitative Study

Rationale: There are limited data on the impact of the coronavirus disease (COVID-19) pandemic on intensive care unit (ICU) recovery clinic care delivery practices. Objectives: We sought to better understand the patient-level factors affecting ICU recovery clinic care and changing clinical thinking during the COVID-19 pandemic. We also sought to understand how the COVID-19 pandemic sparked innovation within ICU recovery clinics. Methods: A multicenter qualitative study was conducted with ICU recovery clinic interprofessional clinicians involved with the Critical and Acute Illness Recovery Organization (CAIRO) between February and March 2021. Data were collected using semistructured interviews and were analyzed using thematic analysis. Key themes were organized in a working analytical framework. Results: Twenty-nine participants from 15 international sites participated in the study. Participants identified three patient-level key themes that influenced care delivery in ICU recovery programs: 1) social isolation, 2) decreased emotional reserve in patients and families, and 3) substantial social care needs. Changes in ICU recovery clinic care delivery occurred at both the clinician level (e.g., growing awareness of healthcare disparities and inequities, recognition of financial effects of illness, refinement of communication skills, increased focus on reconstructing the illness narrative) and the practice level (e.g., expansion of care delivery modes, efforts to integrate social care) in response to each of the patient-level themes. Identified gaps in ICU recovery clinic care delivery during the COVID-19 pandemic included a need for multidisciplinary team members, access to care issues (e.g., digital poverty, health insurance coverage, language barriers), and altered family engagement. Conclusions: This study demonstrates that addressing patient-level factors such as efforts to integrate social care, address financial needs, refine provider communication skills (e.g., empathic listening), and enhance focus on reconstructing the illness narrative became important priorities during the ICU recovery clinic visit during the COVID-19 pandemic. We also identified several ongoing gaps in ICU recovery clinic care delivery that highlight the need for interventions focused on the integration of social and clinic services for critical care survivors.

Implementation of a Follow-Up Program for Intensive Care Unit Survivors

In Intensive Care Unit (ICU) survivors, critical illness has an impact on an individual’s long-term health status and quality of life. Adults who have recovered from intensive care management could develop muscle weakness, neurocognitive impairment, difficulties in managing activities of daily living and to returning to work, and psychological problems such as depression and anxiety. A prospective, observational study was designed. Data were collected from January to December 2018 from a structured follow-up program, at 3 time points after ICU discharge: at seven days, a visit in the general ward, a phone interview at three months and an ambulatory visit at six months. A total of 95 patients were enrolled, 36% female, with a median age of 65 (55–73) years and a median ICU length of stay of 13 (8–20) days. At the seven days follow-up, patients who had a positive Hospital Anxiety and Depression Scale showed a significantly longer time of intubation (p = 0.048) and length of ICU stay (p = 0.023). At three months, we observed a significant relationship between a positive Hospital Anxiety and Depression Scale and a median value of EuroQol-5D (p = 0.048). At six months, we observed that patients who had a positive Post-Traumatic Symptom Scale were significantly younger than the other group. Findings from the present study suggest that a longer time of intubation and length of ICU stay are associated with a higher level of anxiety and depression immediately after ICU discharge. Follow-up programs are recommended to assess and rehabilitate cognitive function at ICU discharge.

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.

Effectiveness of cognitive interventions on cognitive outcomes of adult intensive care unit survivors: A scoping review

BACKGROUND

Cognitive impairments have been identified as significant under-recognised negative sequelae of postintensive care syndrome. No treatment guidelines exist for cognitive interventions addressing the devastating consequences of impairments and their potential impact on outcomes of intensive care unit (ICU) survivors.

AIM

The aim of the study was to identify all available cognitive interventions and measurable outcomes for the cognitive rehabilitation of adult ICU survivors, as reported in published articles. Secondary aims included to critically synthesise existing evidence in improving adult ICU survivors' cognitive outcomes after ICU discharge and to extract implications for future research.

METHODS

A scoping review was conducted based on a rigorous literature search (CINAHL, Embase, MEDLINE, PubMed, SCOPUS, Cochrane Library, and Google Scholar) using predefined keywords. The protocol was based on current guidelines. Eligibility criteria included published (i) experimental and quasi-experimental studies reporting the effects of cognitive interventions on cognitive outcomes of adult critical illness survivors after hospital discharge and (ii) protocols identifying cognitive interventions with predefined cognitive outcome measures.

RESULTS

Seven studies were included: three experimental studies, two quasi-experimental studies, and two published protocols. Significant heterogeneity in the type of interventions, outcome measures, and assessment tools was noted. Interventions included variations of goal management training and an integrated multidisciplinary model. The setting, delivery, and duration of interventions varied. Cognitive outcomes included variations of global cognitive function and executive function. Overall, the evidence on the effects of cognitive interventions, as compared with routine care, in improving global cognitive function is inconclusive. More evidence support exists with respect to improving executive function.

CONCLUSION

Although various cognitive intervention approaches have shown some positive effects on outcomes of ICU survivors after hospital discharge, the high risk of bias and high heterogeneity across studies preclude conclusions about the most appropriate post-ICU care to rehabilitate cognitive deficits in critical care survivors. This review highlighted a number of methodological limitations that require further investigation.

Early anthropometry, strength, and function in survivors of critical illness

BACKGROUND

Critically ill patients experience acute muscle wasting and long-term functional impairments, yet this has been inadequately categorised early in recovery.

OBJECTIVE

This observational study aimed to evaluate anthropometry, strength, and muscle function after intensive care unit discharge.

METHODS

Adult patients able to complete study measures after prolonged intensive care unit stay (≥5 d) were eligible. Demographic and clinical data were collected, and bodyweight, height, triceps skinfold, trunk length, handgrip strength, 6-minute walk test, whole-body dual-energy x-ray absorptiometry, and mid-thigh, knee, and above-ankle circumferences were measured. Body cell mass was calculated from these data. Data are presented as mean (standard deviation) or median [interquartile range].

RESULTS

Fourteen patients (50% male; 57 [10.5] years) were assessed 11.1 (6.9) d after intensive care unit discharge. Patients lost 4.76 (6.66) kg in the intensive care unit. Triceps skinfold thickness (17.00 [8.65] mm) and handgrip strength (12.60 [8.57] kg) were lower than normative data. No patient could commence the 6-minute walk test. Dual-energy x-ray absorptiometry-derived muscle mass correlated with handgrip strength (R = 0.57; 95% confidence interval = 0.06-0.85; p = 0.03), but body cell mass did not.

CONCLUSIONS

Anthropometry and strength in intensive care unit survivors are below normal. Muscle mass derived from dual-energy x-ray absorptiometry correlates with handgrip strength but body cell mass does not.

Sleep Fragmentation and Cognitive Trajectories After Critical Illness

BACKGROUND

ICU survivors can experience both cognitive dysfunction and persistent sleep disturbances after hospitalization. Sleep disturbances have been linked with cognitive impairment in various patient populations, and the apolipoprotein E (APOE) genotype has been linked to sleep-related impairments in cognition.

RESEARCH QUESTION

Is there an association between sleep, long-term cognition, and APOE status in ICU survivors?

STUDY DESIGN AND METHODS

We enrolled 150 patients from five centers who had been mechanically ventilated for at least 3 days; 102 patients survived to ICU discharge. Actigraphy and cognitive testing were undertaken at 7 days, 6 months, and 12 months after ICU discharge, and sleep duration, quality, and timing were estimated by actigraphy. APOE single nucleotide polymorphisms were assessed for each patient.

RESULTS

Actigraphy-estimated sleep fragmentation, but not total sleep time or interdaily stability (estimate of circadian rhythmicity), was associated with worse cognitive impairment at 7 days of ICU discharge. No actigraphy-estimated variable of sleep estimation at 7 days post-ICU discharge predicted cognitive impairment or persistent sleep abnormalities at 6 and 12 months of follow-up in subsequently assessed survivors. Possessing the APOE ε4 allele was not significantly associated with sleep disturbances and its presence did not modify the risk of sleep-related cognitive impairment at follow-up.

INTERPRETATION

Sleep fragmentation estimated by actigraphy was associated with worse cognitive performance in hospital, but not at later time intervals. Further research is needed to better delineate the relationship between persistent sleep disturbances and cognition in larger numbers of ICU survivors.

The role of serum cystatin C in estimation of renal function in survivors of critical illness

PURPOSE

Estimating renal function by serum creatinine after critical illness is a challenging problem. However, the role of cystatin C for estimation of the renal function in survivors of critical illness is unknown. We aimed to compare the performance of serum cystatin C- and serum creatinine-based eGFR against a reference GFR using ^99mTc-diethylenetriaminepentaacetic acid (^99mTc-DTPA) in survivors of critical illness.

MATERIAL AND METHODS

Survivors of critical illness with stable hemodynamics and renal functions were recruited. Their serum creatinine and cystatin C levels were measured. eGFR were calculated by using various equations: 1)CKD-EPI SCysC; 2) Thai eGFR SCysC; 3)CKD-EPI SCr; 4)Thai eGFR SCr; 5)MDRD Caucasian SCr; 6)CKD-EPI SCr-SCysC. The ^99mTc-DTPA plasma clearance was used as a standard eGFR.

RESULTS

Forty-two patients were included. The bias (median percentage difference) between standard GFR and SCysC-based eGFR were 41.97% (95%CI 33.1% to 48.5%) for CKD-EPI SCysC and 31.72% (95%CI 21.1% to 34.9%) for Thai eGFR SCysC. While, the bias between standard GFR and SCr-based eGFR were -11.37 (95%CI -20.9 to 1.6) for CKD-EPI SCr, -18.30 (95%CI -26.3 to -10.6) for Thai eGFR SCr, and -27.17 (-43.7 to -19.1) for MDRD Caucasian SCr.

CONCLUSION

In survivors of critical illness, we demonstrated limitations of estimating GFR by both currently available SCysC and SCr-based equations. Therefore, further studies are still needed to develop better eGFR equations.

Feasibility and acceptability of a self-managed exercise to rhythmic music intervention for ICU survivors

BACKGROUND

Post-ICU rehabilitation is a challenging clinical issue for patients discharged from an Intensive Care Unit ("ICU survivors"). Our exercise to rhythmic music intervention was designed to allow ICU survivors to self-manage their exercise by following a personalized, recorded exercise playlist.

AIM

Our study reports the feasibility and acceptability of an innovative music intervention among ICU survivors enrolled in a randomized controlled pilot study.

METHODS

ICU survivors, admitted in ICU for at least 5 days and cognitively intact, were randomly assigned to an exercise to rhythmic music group (n = 10) or an active control group (n = 10). Participants in the music group were taught to self-manage exercise by listening to a recorded playlist of instructions and music-facilitated movements tailored to their musical preference and exercise ability. Participants in the control group were provided a brochure with exercise instructions. After 5 days or at hospital discharge, participants completed an 8-item acceptability questionnaire and were interviewed. Content analysis was conducted.

RESULTS

18 Participants were included for final analysis. Participants were 61.8 ± 14.7 years old, predominantly male (66.7%), and Caucasian (55.6%). Results demonstrated feasibility, as the study team was able to meet the enrollment goal of 5-6 participants per month. Three themes related to general, physical, and psychosocial benefits were identified. Based on positive feedback, the exercise to rhythmic music intervention was deemed acceptable.

CONCLUSION

The exercise to rhythmic music intervention was feasible and acceptable, suggesting that clinical trials with larger sample sizes should investigate the effects of the intervention on outcomes among ICU survivors.

Changes in frailty among ICU survivors and associated factors: Results of a one-year prospective cohort study using the Dutch Clinical Frailty Scale

PURPOSE

Frailty is an important predictor for the prognosis of intensive care unit (ICU) patients. This study examined changes in frailty in the year after ICU admission, and its associated factors.

MATERIALS AND METHODS

Prospective cohort study including adult ICU patients admitted between July 2016-December 2017. Frailty was measured using the Clinical Frailty Scale (CFS), before ICU admission, at hospital discharge, and three and 12 months after ICU admission. Multivariable linear regression was used to explore factors associated with frailty changes.

RESULTS

Frailty levels changed among 1300 ICU survivors, with higher levels at hospital discharge and lower levels in the following months. After one year were 42% of the unplanned, and 27% of the planned patients more frail. For both groups were older age, longer hospital length of stay, and discharge location associated with being more frail. Male sex, higher education level and mechanical ventilation were associated with being less frail in the planned patients.

CONCLUSION

One year after ICU admission, 42% and 27% of the unplanned and planned ICU patients, respectively, were more frail. Insight in the associated factors will help to identify patients at risk, and may help in informing patients and their family members.

Malnutrition, Critical Illness Survivors, and Postdischarge Outcomes: A Cohort Study

BACKGROUND

We hypothesized that preexisting malnutrition in patients who survived critical care would be associated with adverse outcomes following hospital discharge.

METHODS

We performed an observational cohort study in 1 academic medical center in Boston. We studied 23,575 patients, aged ≥18 years, who received critical care between 2004 and 2011 and survived hospitalization.

RESULTS

The exposure of interest was malnutrition determined at intensive care unit (ICU) admission by a registered dietitian using clinical judgment and on data related to unintentional weight loss, inadequate nutrient intake, and wasting of muscle mass and/or subcutaneous fat. The primary outcome was 90-day postdischarge mortality. Secondary outcome was unplanned 30-day hospital readmission. Adjusted odds ratios were estimated by logistic regression models adjusted for age, race, sex, Deyo-Charlson Index, surgical ICU, sepsis, and acute organ failure. In the cohort, the absolute risk of 90-day postdischarge mortality was 5.9%, 11.7%, 15.8%, and 21.9% in patients without malnutrition, those at risk of malnutrition, nonspecific malnutrition, and protein-energy malnutrition, respectively. The odds of 90-day postdischarge mortality in patients at risk of malnutrition, nonspecific malnutrition, and protein-energy malnutrition fully adjusted were 1.77 (95% confidence interval [CI], 1.23-2.54), 2.51 (95% CI, 1.36-4.62), and 3.72 (95% CI, 2.16-6.39), respectively, relative to patients without malnutrition. Furthermore, the presence of malnutrition is a significant predictor of the odds of unplanned 30-day hospital readmission.

CONCLUSIONS

In patients treated with critical care who survive hospitalization, preexisting malnutrition is a robust predictor of subsequent mortality and unplanned hospital readmission.

Patients' Perceptions of an Exercise Program Delivered Following Discharge From Hospital After Critical Illness (the Revive Trial)

BACKGROUND

The REVIVE randomized controlled trial (RCT) investigated the effectiveness of an individually tailored (personalized) exercise program for patients discharged from hospital after critical illness. By including qualitative methods, we aimed to explore patients' perceptions of engaging in the exercise program.

METHODS

Patients were recruited from general intensive care units in 6 hospitals in Northern Ireland. Patients allocated to the exercise intervention group were invited to participate in this qualitative study. Independent semistructured interviews were conducted at 6 months after randomization. Interviews were audio-recorded, transcribed, and content analysis used to explore themes arising from the data.

RESULTS

Of 30 patients allocated to the exercise group, 21 completed the interviews. Patients provided insight into the physical and mental sequelae they experienced following critical illness. There was a strong sense of patients' need for the exercise program and its importance for their recovery following discharge home. Key facilitators of the intervention included supervision, tailoring of the exercises to personal needs, and the exercise manual. Barriers included poor mental health, existing physical limitations, and lack of motivation. Patients' views of outcome measures in the REVIVE RCT varied. Many patients were unsure about what would be the best way of measuring how the program affected their health.

CONCLUSIONS

This qualitative study adds an important perspective on patients' attitude to an exercise intervention following recovery from critical illness, and provides insight into the potential facilitators and barriers to delivery of the program and how programs should be evolved for future trials.

Posttraumatic stress in intensive care unit survivors - a prospective study

Aims: This study aimed to estimate the prevalence of severe Posttraumatic Stress Disorder (PTSD) symptoms and to identify factors associated with PTSD in survivors of intensive care unit (ICU) treatment following traumatic injury. Methods: Fifty-two patients who were admitted to an ICU through the emergency ward following traumatic injury were prospectively followed. Information on injury severity and ICU treatment were obtained through medical records. Demographic information and measures of acute stress symptoms, experienced social support, coping style, sense of coherence (SOC) and locus of control were assessed within one-month post-accident (T1). At the six months follow-up (T2), PTSD was assessed with the Harvard Trauma Questionnaire (HTQ). Results: In the six months follow-up, 10 respondents (19.2%) had HTQ total scores reaching a level suggestive of PTSD (N = 52), and 11 respondents (21%) had symptom levels indicating subclinical PTSD. Female, five illness factors: coma time, mechanical ventilation, sedation, benzodiazepine, pain relieving medication, and four psychological factors: symptoms of acute stress (T1), fear of death and/or feeling completely helpless and powerless in relation to the accident and/or ICU (T1), SOC (T1) and more external locus of control (T1) correlated significantly with PTSD symptoms at T2. In the linear regression analysis, female, length of sedation, dissociation (T1), hypervigilance (T1), and external locus of control predicted 58% of the variation of PTSD. Conclusions: High levels of PTSD symptoms occurred in 19.2% of respondents in six months following traumatic injury requiring ICU admission. Screening for the variables gender, length of sedation, dissociation, hypervigilance, and locus of control after ICU admission following traumatic injuries may help to predict who will develop PTSD.
