"Like fighting a fire with a water pistol": A qualitative study of the work experiences of critical care nurses during the COVID-19 pandemic.

AIM: To understand the experience of critical care nurses during the COVID-19 pandemic, through the application of the Job-Demand-Resource model of occupational stress. DESIGN: Qualitative interview study. METHODS: Twenty-eight critical care nurses (CCN) working in ICU in the UK NHS during the COVID-19 pandemic took part in semi-structured interviews between May 2021 and May 2022. Interviews were guided by the constructs of the Job-Demand Resource model. Data were analysed using framework analysis. RESULTS: The most difficult job demands were the pace and amount, complexity, physical and emotional effort of their work. Prolonged high demands led to CCN experiencing emotional and physical exhaustion, burnout, post-traumatic stress symptoms and impaired sleep. Support from colleagues and supervisors was a core job resource. Sustained demands and impaired physical and psychological well-being had negative organizational consequences with CCN expressing increased intention to leave their role. CONCLUSIONS: The combination of high demands and reduced resources had negative impacts on the psychological well-being of nurses which is translating into increased consideration of leaving their profession. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: The full impacts of the pandemic on the mental health of CCN are unlikely to resolve without appropriate interventions. IMPACT: Managers of healthcare systems should use these findings to inform: (i) the structure and organization of critical care workplaces so that they support staff to be well, and (ii) supportive interventions for staff who are carrying significant psychological distress as a result of working during and after the pandemic. These changes are required to improve staff recruitment and retention. REPORTING METHOD: We used the COREQ guidelines for reporting qualitative studies. PATIENT AND PUBLIC CONTRIBUTION: Six CCN provided input to survey content and interview schedule. Two authors and members of the study team (T.S. and S.C.) worked in critical care during the pandemic.

Support after COVID-19 study: a mixed-methods cross-sectional study to develop recommendations for practice.

Objectives of study stage 1 were to: explore people's experiences of illness due to COVID-19 while feeling socially isolated or socially isolating; identify perceptions of what would support recovery; and synthesise insights into recommendations for supporting people after COVID-19. Study stage 2 objectives were to engage stakeholders in evaluating these recommendations and analyse likely influences on access to the support identified. DESIGN: A two-stage, multimethod cross-sectional study was conducted from a postpositivist perspective. Stage 1 included an international online survey of people's experiences of illness, particularly COVID-19, in isolation (n=675 full responses). Stage 2 involved a further online survey (n=43), two tweetchats treated as large online focus groups (n=60 and n=27 people tweeting), two smaller focus groups (both n=4) and one interview (both using MS teams). SETTING: Stage 1 had an international emphasis, although 87% of respondents were living in the UK. Stage 2 focused on the UK. PARTICIPANTS: Anyone aged 18+ and able to complete a survey in English could participate. Stage 2 included health professionals, advocates and people with lived experience. MAIN OUTCOME MEASURES: Descriptive data and response categories derived from open responses to the survey and the qualitative data. RESULTS: Of those responding fully to stage 1 (mean age 44 years); 130 (19%) had experienced COVID-19 in isolation; 45 had recovered, taking a mean of 5.3 (range 1-54) weeks. 85 did not feel they had recovered; fatigue and varied 'other' symptoms were most prevalent and also had most substantial negative impacts. Our draft recommendations were highly supported by respondents to stage 2 and refined to produce final recommendations. CONCLUSIONS: Recommendations support access to progressive intensity and specialism of support, addressing access barriers that might inadvertently increase health inequalities. Multidisciplinary collaboration and learning are crucial, including the person with COVID-19 and/or Long Covid in the planning and decision making throughout.

A Constructivist Grounded Theory of Staff Experiences Relating to Early Mobilisation of Mechanically Ventilated Patients in Intensive Care.

Early mobilisation of mechanically ventilated patients has been suggested to be effective in mitigating muscle weakness, yet it is not a common practice. Understanding staff experiences is crucial to gain insights into what might facilitate or hinder its implementation. In this constructivist grounded theory study, data from two Scottish intensive care units were collected to understand healthcare staff experiences relating to early mobilisation in mechanical ventilation. Data included observations of mobilisation activities, individual staff interviews and two focus groups with multidisciplinary staff. Managing Risks emerged as the core category and was theorised using the concept of risk. The middle-range theory developed in this study suggests that the process of early mobilisation starts by staff defining patient status and includes a process of negotiating patient safety, which in turn enables performing accountable mobilisation within the dynamic context of an intensive care unit setting.

Work-related stress: the impact of COVID-19 on critical care and redeployed nurses: a mixed-methods study.

INTRODUCTION: We need to understand the impact of COVID-19 on critical care nurses (CCNs) and redeployed nurses and National Health Service (NHS) organisations. METHODS AND ANALYSIS: This is a mixed-methods study (QUANT-QUAL), underpinned by a theoretical model of occupational stress, the Job Demand-Resources Model (JD-R). Participants are critical care and redeployed nurses from Scottish and three large English units.Phase 1 is a cross-sectional survey in part replicating a pre-COVID-19 study and results will be compared with this data. Linear and logistic regression analysis will examine the relationship between antecedent, demographic and professional variables on health impairment (burnout syndrome, mental health, post-traumatic stress symptoms), motivation (work engagement, commitment) and organisational outcomes (intention to remain in critical care nursing and quality of care). We will also assess the usefulness of a range of resources provided by the NHS and professional organisations.To allow in-depth exploration of individual experiences, phase 2 will be one-to-one semistructured interviews with 25 CCNs and 10 redeployed nurses. The JD-R model will provide the initial coding framework to which the interview data will be mapped. The remaining content will be analysed inductively to identify and chart content that is not captured by the model. In this way, the adequacy of the JD-R model is examined robustly and its expression in this context will be detailed. ETHICS AND DISSEMINATION: Ethics approval was granted from the University of Aberdeen CERB2020101993. We plan to disseminate findings at stakeholder events, publish in peer-reviewed journals and at present at national and international conferences.

Person-Centered Healthcare Practice in a Pandemic Context: An Exploration of People's Experience of Seeking Healthcare Support.

Background: The recent COVID-19 pandemic increased pressure upon healthcare resources resulting in compromised health services. Enforced national lockdown led to people being unable to access essential services in addition to limiting contact with social support networks. The novel coronavirus, and subsequent condition known as long covid were not well-understood and clinicians were not supported by existing guidelines or pathways. Our study explored people's experiences of healthcare during this period with a person-centered "lens." Methods: Ninety-seven people participated in our online survey about their experiences of the pandemic, particularly while socially isolated and their experiences of healthcare. Following completion of the survey, 11 of these participants agreed to further semi-structured interviews to explore this further in their own words. Interview conversations were transcribed, checked; together with the responses to open questions in the survey. The data were then analyzed thematically by members of the research team. We conducted framework analysis from a post-positivist perspective, using the Person-centered Practice Framework to explore participants' experiences. Results: There were few examples of people describing person-centered care. People experienced barriers to accessing support, and negative experiences of care that represented complexities enacting person-centered care at each level of the framework (processes, practice environment, prerequisites, and macro context). These barriers were influenced greatly by the pandemic, for example, with health professionals being harder to access. Some experiences related to the ways in which health professionals responded to the context, for example, positive examples included active listening, recognition of people's experiences, seeking to find out more, and engaging in collaborative problem-solving. Discussion: People want to feel heard, supported to navigate healthcare systems, source trustworthy information, find appropriate services, and collaborate in learning and problem-solving with healthcare professionals. There have been enormous challenges to the provision of healthcare throughout the pandemic. Moving forward is crucial with emphasis on overcoming barriers to person-centered healthcare. This should focus on steps now and also in planning for the possibility of further rapid changes in the demand for and provision of healthcare.

Polypharmacy and emergency readmission to hospital after critical illness: a population-level cohort study.

BACKGROUND: Polypharmacy is common and closely linked to drug interactions. The impact of polypharmacy has not been previously quantified in survivors of critical illness who have reduced resilience to stressors. Our aim was to identify factors associated with preadmission polypharmacy and ascertain whether polypharmacy is an independent risk factor for emergency readmission to hospital after discharge from a critical illness. METHODS: A population-wide cohort study consisting of patients admitted to all Scottish general ICUs between January 1, 2011 and December 31, 2013, whom survived their ICU stay. Patients were stratified by presence of preadmission polypharmacy, defined as being prescribed five or more regular medications. The primary outcome was emergency hospital readmission within 1 yr of discharge from index hospital stay. RESULTS: Of 23 844 ICU patients, 29.9% were identified with polypharmacy (n=7138). Factors associated with polypharmacy included female sex, increasing age, and social deprivation. Emergency 1-yr hospital readmission was significantly higher in the polypharmacy cohort (51.8% vs 35.8%, P<0.001). After confounder adjustment, patients with polypharmacy had a 22% higher hazard of emergency 1-yr readmission (adjusted hazard ratio 1.22, 95% confidence interval 1.16-1.28, P<0.001). On a linear scale of polypharmacy each additional prescription conferred a 3% increase in hazard of emergency readmission by 1 yr (adjusted hazard ratio 1.03, 95% confidence interval 1.02-1.03, P<0.001). CONCLUSIONS: This national cohort study of ICU survivors demonstrates that preadmission polypharmacy is an independent risk factor for emergency readmission. In an ever-growing era of polypharmacy, this risk factor may represent a substantial burden in the at-risk post-intensive care population.

Early mobilisation in mechanically ventilated patients: a systematic integrative review of definitions and activities.

BACKGROUND: Mechanically ventilated patients often develop muscle weakness post-intensive care admission. Current evidence suggests that early mobilisation of these patients can be an effective intervention in improving their outcomes. However, what constitutes early mobilisation in mechanically ventilated patients (EM-MV) remains unclear. We aimed to systematically explore the definitions and activity types of EM-MV in the literature. METHODS: Whittemore and Knafl's framework guided this review. CINAHL, MEDLINE, EMBASE, PsycINFO, ASSIA, and Cochrane Library were searched to capture studies from 2000 to 2018, combined with hand search of grey literature and reference lists of included studies. The Critical Appraisal Skills Programme tools were used to assess the methodological quality of included studies. Data extraction and quality assessment of studies were performed independently by each reviewer before coming together in sub-groups for discussion and agreement. An inductive and data-driven thematic analysis was undertaken on verbatim extracts of EM-MV definitions and activities in included studies. RESULTS: Seventy-six studies were included from which four major themes were inferred: (1) non-standardised definition, (2) contextual factors, (3) negotiated process and (4) collaboration between patients and staff. The first theme indicates that EM-MV is either not fully defined in studies or when a definition is provided this is not standardised across studies. The remaining themes reflect the diversity of EM-MV activities which depends on patients' characteristics and ICU settings; the negotiated decision-making process between patients and staff; and their interdependent relationship during the implementation. CONCLUSIONS: This review highlights the absence of an agreed definition and on what constitutes early mobilisation in mechanically ventilated patients. To advance research and practice an agreed and shared definition is a pre-requisite.

Predicting risk of unplanned hospital readmission in survivors of critical illness: a population-level cohort study.

BACKGROUND: Intensive care unit (ICU) survivors experience high levels of morbidity after hospital discharge and are at high risk of unplanned hospital readmission. Identifying those at highest risk before hospital discharge may allow targeting of novel risk reduction strategies. We aimed to identify risk factors for unplanned 90-day readmission, develop a risk prediction model and assess its performance to screen for ICU survivors at highest readmission risk. METHODS: Population cohort study linking registry data for patients discharged from general ICUs in Scotland (2005-2013). Independent risk factors for 90-day readmission and discriminant ability (c-index) of groups of variables were identified using multivariable logistic regression. Derivation and validation risk prediction models were constructed using a time-based split. RESULTS: Of 55 975 ICU survivors, 24.1% (95%CI 23.7% to 24.4%) had unplanned 90-day readmission. Pre-existing health factors were fair discriminators of readmission (c-index 0.63, 95% CI 0.63 to 0.64) but better than acute illness factors (0.60) or demographics (0.54). In a subgroup of those with no comorbidity, acute illness factors (0.62) were better discriminators than pre-existing health factors (0.56). Overall model performance and calibration in the validation cohort was fair (0.65, 95% CI 0.64 to 0.66) but did not perform sufficiently well as a screening tool, demonstrating high false-positive/false-negative rates at clinically relevant thresholds. CONCLUSIONS: Unplanned 90-day hospital readmission is common. Pre-existing illness indices are better predictors of readmission than acute illness factors. Identifying additional patient-centred drivers of readmission may improve risk prediction models. Improved understanding of risk factors that are amenable to intervention could improve the clinical and cost-effectiveness of post-ICU care and rehabilitation.

Unplanned early hospital readmission among critical care survivors: a mixed methods study of patients and carers.

BACKGROUND: Many intensive care (ICU) survivors experience early unplanned hospital readmission, but the reasons and potential prevention strategies are poorly understood. We aimed to understand contributors to readmissions from the patient/carer perspective. METHODS: This is a mixed methods study with qualitative data taking precedence. Fifty-eight ICU survivors and carers who experienced early unplanned rehospitalisation were interviewed. Thematic analysis was used to identify factors contributing to readmissions, and supplemented with questionnaire data measuring patient comorbidity and carer strain, and importance rating scales for factors that contribute to readmissions in other patient groups. Data were integrated iteratively to identify patterns, which were discussed in five focus groups with different patients/carers who also experienced readmissions. Major patterns and contexts in which unplanned early rehospitalisation occurred in ICU survivors were described. RESULTS: Interviews suggested 10 themes comprising patient-level and system-level issues. Integration with questionnaire data, pattern exploration and discussion at focus groups suggested two major readmission contexts. A 'complex health and psychosocial needs' context occurred in patients with multimorbidity and polypharmacy, who frequently also had significant psychological problems, mobility issues, problems with specialist aids/equipment and fragile social support. These patients typically described inadequate preparation for hospital discharge, poor communication between secondary/primary care, and inadequate support with psychological care, medications and goal setting. This complex multidimensional situation contrasted markedly with the alternative 'medically unavoidable' readmission context. In these patients medical issues/complications primarily resulted in hospital readmission, and the other issues were absent or not considered important. CONCLUSIONS: Although some readmissions are medically unavoidable, for many ICU survivors complex health and psychosocial issues contribute concurrently to early rehospitalisation. Care pathways that anticipate and institute anticipatory multifaceted support for these patients merit further development and evaluation.

Determinants of Health-Related Quality of Life After ICU: Importance of Patient Demographics, Previous Comorbidity, and Severity of Illness.

OBJECTIVES: ICU survivors frequently report reduced health-related quality of life, but the relative importance of preillness versus acute illness factors in survivor populations is not well understood. We aimed to explore health-related quality of life trajectories over 12 months following ICU discharge, patterns of improvement, or deterioration over this period, and the relative importance of demographics (age, gender, social deprivation), preexisting health (Functional Comorbidity Index), and acute illness severity (Acute Physiology and Chronic Health Evaluation II score, ventilation days) as determinants of health-related quality of life and relevant patient-reported symptoms during the year following ICU discharge. DESIGN: Nested cohort study within a previously published randomized controlled trial. SETTING: Two ICUs in Edinburgh, Scotland. PATIENTS: Adult ICU survivors (n = 240) who required more than 48 hours of mechanical ventilation. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: We prospectively collected data for age, gender, social deprivation (Scottish index of multiple deprivation), preexisting comorbidity (Functional Comorbidity Index), Acute Physiology and Chronic Health Evaluation II score, and days of mechanical ventilation. Health-related quality of life (Medical Outcomes Study Short Form version 2 Physical Component Score and Mental Component Score) and patient-reported symptoms (appetite, fatigue, pain, joint stiffness, and breathlessness) were measured at 3, 6, and 12 months. Mean Physical Component Score and Mental Component Score were reduced at all time points with minimal change between 3 and 12 months. In multivariable analysis, increasing pre-ICU comorbidity count was strongly associated with lower health-related quality of life (Physical Component Score ß = -1.56 [-2.44 to -0.68]; p = 0.001; Mental Component Score ß = -1.45 [-2.37 to -0.53]; p = 0.002) and more severe self-reported symptoms. In contrast, Acute Physiology and Chronic Health Evaluation II score and mechanical ventilation days were not associated with health-related quality of life. Older age (ß = 0.33 [0.19-0.47]; p < 0.001) and lower social deprivation (ß = 1.38 [0.03-2.74]; p = 0.045) were associated with better Mental Component Score health-related quality of life. CONCLUSIONS: Preexisting comorbidity counts, but not severity of ICU illness, are strongly associated with health-related quality of life and physical symptoms in the year following critical illness.

Treadmill training to improve mobility for people with sub-acute stroke: a phase II feasibility randomized controlled trial.

OBJECTIVE: This phase II study investigated the feasibility and potential effectiveness of treadmill training versus normal gait re-education for ambulant and non-ambulant people with sub-acute stroke delivered as part of normal clinical practice. DESIGN: A single-blind, feasibility randomized controlled trial. SETTING: Four hospital-based stroke units. SUBJECTS: Participants within three months of stroke onset. INTERVENTIONS: Participants were randomized to treadmill training (minimum twice weekly) plus normal gait re-education or normal gait re-education only (control) for up to eight weeks. MAIN MEASURES: Measures were taken at baseline, after eight weeks of intervention and at six-month follow-up. The primary outcome was the Rivermead Mobility Index. Other measures included the Functional Ambulation Category, 10-metre walk, 6-minute walk, Barthel Index, Motor Assessment Scale, Stroke Impact Scale and a measure of confidence in walking. RESULTS: In all, 77 patients were randomized, 39 to treadmill and 38 to control. It was feasible to deliver treadmill training to people with sub-acute stroke. Only two adverse events occurred. No statistically significant differences were found between groups. For example, Rivermead Mobility Index, median (interquartile range (IQR)): after eight weeks treadmill 5 (4-9), control 6 (4-11) p = 0.33; or six-month follow-up treadmill 8.5 (3-12), control 8 (6-12.5) p = 0.42. The frequency and intensity of intervention was low. CONCLUSION: Treadmill training in sub-acute stroke patients was feasible but showed no significant difference in outcomes when compared to normal gait re-education. A large definitive randomized trial is now required to explore treadmill training in normal clinical practice.

'Intensive care unit survivorship' - a constructivist grounded theory of surviving critical illness.

AIMS AND OBJECTIVES: To theorise intensive care unit survivorship after a critical illness based on longitudinal qualitative data. BACKGROUND: Increasingly, patients survive episodes of critical illness. However, the short- and long-term impact of critical illness includes physical, psychological, social and economic challenges long after hospital discharge. An appreciation is emerging that care needs to extend beyond critical illness to enable patients to reclaim their lives postdischarge with the term 'survivorship' being increasingly used in this context. What constitutes critical illness survivorship has, to date, not been theoretically explored. DESIGN: Longitudinal qualitative and constructivist grounded theory. Interviews (n = 46) with 17 participants were conducted at four time points: (1) before discharge from hospital, (2) four to six weeks postdischarge, (3) six months and (4) 12 months postdischarge across two adult intensive care unit setting. METHOD: Individual face-to-face interviews. Data analysis followed the principles of Charmaz's constructivist grounded theory. 'Intensive care unit survivorship' emerged as the core category and was theorised using concepts such as status passages, liminality and temporality to understand the various transitions participants made postcritical illness. FINDINGS: Intensive care unit survivorship describes the unscheduled status passage of falling critically ill and being taken to the threshold of life and the journey to a life postcritical illness. Surviving critical illness goes beyond recovery; surviving means 'moving on' to life postcritical illness. 'Moving on' incorporates a redefinition of self that incorporates any lingering intensive care unit legacies and being in control of one's life again. RELEVANCE TO CLINICAL PRACTICE: For healthcare professionals and policymakers, it is important to realise that recovery and transitioning through to survivorship happen within an individual's time frame, not a schedule imposed by the healthcare system. Currently, there are no care pathways or policies in place for critical illness survivors that would support intensive care unit survivors and their families in the transitions to survivorship.

Exercise rehabilitation following intensive care unit discharge for recovery from critical illness: executive summary of a Cochrane Collaboration systematic review.

Skeletal muscle wasting and weakness are major complications of critical illness and underlie the profound physical and functional impairments experienced by survivors after discharge from the intensive care unit (ICU). Exercise-based rehabilitation has been shown to be beneficial when delivered during ICU admission. This review aimed to determine the effectiveness of exercise rehabilitation initiated after ICU discharge on primary outcomes of functional exercise capacity and health-related quality of life. We sought randomized controlled trials, quasi-randomized controlled trials, and controlled clinical trials comparing an exercise intervention commenced after ICU discharge vs. any other intervention or a control or 'usual care' programme in adult survivors of critical illness. Cochrane Central Register of Controlled Trials, Medical Literature Analysis and Retrieval System Online (MEDLINE), Excerpta Medica Database, and Cumulative Index to Nursing and Allied Health Literature databases were searched up to February 2015. Dual, independent screening of results, data extraction, and quality appraisal were performed. We included six trials involving 483 patients. Overall quality of evidence for both outcomes was very low. All studies evaluated functional exercise capacity, with three reporting positive effects in favour of the intervention. Only two studies evaluated health-related quality of life and neither reported differences between intervention and control groups. Meta-analyses of data were precluded due to variation in study design, types of interventions, and selection and reporting of outcome measurements. We were unable to determine an overall effect on functional exercise capacity or health-related quality of life of interventions initiated after ICU discharge for survivors of critical illness. Findings from ongoing studies are awaited. Future studies need to address methodological aspects of study design and conduct to enhance rigour, quality, and synthesis.

Patient and carer experience of hospital-based rehabilitation from intensive care to hospital discharge: mixed methods process evaluation of the RECOVER randomised clinical trial.

OBJECTIVES: To explore and compare patient/carer experiences of rehabilitation in the intervention and usual care arms of the RECOVER trial (ISRCTN09412438); a randomised controlled trial of a complex intervention of post-intensive care unit (ICU) acute hospital-based rehabilitation following critical illness. DESIGN: Mixed methods process evaluation including comparison of patients' and carers' experience of usual care versus the complex intervention. We integrated and compared quantitative data from a patient experience questionnaire (PEQ) with qualitative data from focus groups with patients and carers. SETTING: Two university-affiliated hospitals in Scotland. PARTICIPANTS: 240 patients discharged from ICU who required ≥48 hours of mechanical ventilation were randomised into the trial (120 per trial arm). Exclusion criteria comprised: primary neurologic diagnosis, palliative care, current/planned home ventilation and age <18 years. 182 patients completed the PEQ at 3 months postrandomisation. 22 participants (14 patients and 8 carers) took part in focus groups (2 per trial group) at >3 months postrandomisation. INTERVENTIONS: A complex intervention of post-ICU acute hospital rehabilitation, comprising enhanced physiotherapy, nutritional care and information provision, case-managed by dedicated rehabilitation assistants (RAs) working within existing ward-based clinical teams, delivered between ICU discharge and hospital discharge. Comparator was usual care. OUTCOME MEASURES: A novel PEQ capturing patient-reported aspects of quality care. RESULTS: The PEQ revealed statistically significant between-group differences across 4 key intervention components: physiotherapy (p=0.039), nutritional care (p=0.038), case management (p=0.045) and information provision (p<0.001), suggesting greater patient satisfaction in the intervention group. Focus group data strongly supported and helped explain these findings. Specifically, case management by dedicated RAs facilitated greater access to physiotherapy, nutritional care and information that cut across disciplinary boundaries and staffing constraints. Patients highly valued its individualisation according to their needs, abilities and preferences. CONCLUSIONS: Case management by dedicated RAs improves patients' experiences of post-ICU hospital-based rehabilitation and increases perceived quality of care.

PReventing early unplanned hOspital readmission aFter critical ILlnEss (PROFILE): protocol and analysis framework for a mixed methods study.

INTRODUCTION: Survivors of critical illness experience multidimensional disabilities that reduce quality of life, and 25-30% require unplanned hospital readmission within 3 months following index hospitalisation. We aim to understand factors associated with unplanned readmission; develop a risk model to identify intensive care unit (ICU) survivors at highest readmission risk; understand the modifiable and non-modifiable readmission drivers; and develop a risk assessment tool for identifying patients and areas for early intervention. METHODS AND ANALYSIS: We will use mixed methods with concurrent data collection. Quantitative data will comprise linked healthcare records for adult Scottish residents requiring ICU admission (1 January 2000-31 December 2013) who survived to hospital discharge. The outcome will be unplanned emergency readmission within 90 days of index hospital discharge. Exposures will include pre-ICU demographic data, comorbidities and health status, and critical illness variables representing illness severity. Regression analyses will be used to identify factors associated with increased readmission risk, and to develop and validate a risk prediction model. Qualitative data will comprise recorded/transcribed interviews with up to 60 patients and carers recently experiencing unplanned readmissions in three health board regions. A deductive and inductive thematic analysis will be used to identify factors contributing to readmissions and how they may interact. Through iterative triangulation of quantitative and qualitative data, we will develop a construct/taxonomy that captures reasons and drivers for unplanned readmission. We will validate and further refine this in focus groups with patients/carers who experienced readmissions in six Scottish health board regions, and in consultation with an independent expert group. A tool will be developed to screen for ICU survivors at risk of readmission and inform anticipatory interventions. ETHICS AND DISSEMINATION: Data linkage has approval but does not require ethical approval. The qualitative study has ethical approval. Dissemination with key healthcare stakeholders and policymakers is planned. TRIAL REGISTRATION NUMBER: UKCRN18023.

Physical rehabilitation interventions for adult patients during critical illness: an overview of systematic reviews.

BACKGROUND: Physical rehabilitation interventions aim to ameliorate the effects of critical illness-associated muscle dysfunction in survivors. We conducted an overview of systematic reviews (SR) evaluating the effect of these interventions across the continuum of recovery. METHODS: Six electronic databases (Cochrane Library, CENTRAL, DARE, Medline, Embase, and Cinahl) were searched. Two review authors independently screened articles for eligibility and conducted data extraction and quality appraisal. Reporting quality was assessed and the Grading of Recommendations Assessment, Development and Evaluation approach applied to summarise overall quality of evidence. RESULTS: Five eligible SR were included in this overview, of which three included meta-analyses. Reporting quality of the reviews was judged as medium to high. Two reviews reported moderate-to-high quality evidence of the beneficial effects of physical therapy commencing during intensive care unit (ICU) admission in improving critical illness polyneuropathy/myopathy, quality of life, mortality and healthcare utilisation. These interventions included early mobilisation, cycle ergometry and electrical muscle stimulation. Two reviews reported very low to low quality evidence of the beneficial effects of electrical muscle stimulation delivered in the ICU for improving muscle strength, muscle structure and critical illness polyneuropathy/myopathy. One review reported that due to a lack of good quality randomised controlled trials and inconsistency in measuring outcomes, there was insufficient evidence to support beneficial effects from physical rehabilitation delivered post-ICU discharge. CONCLUSIONS: Patients derive short-term benefits from physical rehabilitation delivered during ICU admission. Further robust trials of electrical muscle stimulation in the ICU and rehabilitation delivered following ICU discharge are needed to determine the long-term impact on patient care. This overview provides recommendations for design of future interventional trials and SR. TRIAL REGISTRATION NUMBER: CRD42015001068.

Systemic inflammation after critical illness: relationship with physical recovery and exploration of potential mechanisms.

BACKGROUND: Physical recovery following critical illness is slow, often incomplete and is resistant to rehabilitation interventions. We aimed to explore the contribution of persisting inflammation to recovery, and investigated the potential role of human cytomegalovirus (HCMV) infection in its pathogenesis. METHODS: In an a priori nested inflammatory biomarker study in a post-intensive care unit (ICU) rehabilitation trial (RECOVER; ISRCTN09412438), surviving adult ICU patients ventilated >48 h were enrolled at ICU discharge and blood sampled at ICU discharge (n=184) and 3 month follow-up (N=123). C-reactive protein (CRP), human neutrophil elastase (HNE), interleukin (IL)-1ß, IL-6, IL-8, transforming growth factor ß1 (TGFß1) and secretory leucocyte protease inhibitor (SLPI) were measured. HCMV IgG status was determined (previous exposure), and DNA PCR measured among seropositive patients (lytic infection). Physical outcome measures including the Rivermead Mobility Index (RMI) were measured at 3 months. RESULTS: Many patients had persisting inflammation at 3 months (CRP >3 mg/L in 59%; >10 mg/L in 28%), with proinflammatory phenotype (elevated HNE, IL-6, IL-8, SLPI; low TGFß1). Poorer mobility (RMI) was associated with higher CRP (ß=0.13; p<0.01) and HNE (ß=0.32; p=0.03), even after adjustment for severity of acute illness and pre-existing co-morbidity (CRP ß=0.14; p<0.01; HNE ß=0.30; p=0.04). Patients seropositive for HCMV at ICU discharge (63%) had a more proinflammatory phenotype at 3 months than seronegative patients, despite undetectable HMCV by PCR testing. CONCLUSIONS: Inflammation is prevalent after critical illness and is associated with poor physical recovery during the first 3 months post-ICU discharge. Previous HCMV exposure is associated with a proinflammatory phenotype despite the absence of detectable systemic viraemia. TRIAL REGISTRATION NUMBER: ISRCTN09412438, post results.

Physical rehabilitation interventions for adult patients with critical illness across the continuum of recovery: an overview of systematic reviews protocol.

BACKGROUND: Patients admitted to the intensive care unit with critical illness often experience significant physical impairments, which typically persist for many years following resolution of the original illness. Physical rehabilitation interventions that enhance restoration of physical function have been evaluated across the continuum of recovery following critical illness including within the intensive care unit, following discharge to the ward and beyond hospital discharge. Multiple systematic reviews have been published appraising the expanding evidence investigating these physical rehabilitation interventions, although there appears to be variability in review methodology and quality. We aim to conduct an overview of existing systematic reviews of physical rehabilitation interventions for adult intensive care patients across the continuum of recovery. METHODS/DESIGN: This protocol has been developed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocol (PRISMA-P) guidelines. We will search the Cochrane Systematic Review Database, Database of Abstracts of Reviews of Effectiveness, Cochrane Central Register of Controlled Trials, MEDLINE, Excerpta Medica Database and Cumulative Index to Nursing and Allied Health Literature databases. We will include systematic reviews of randomised controlled trials of adult patients, admitted to the intensive care unit and who have received physical rehabilitation interventions at any time point during their recovery. Data extraction will include systematic review aims and rationale, study types, populations, interventions, comparators, outcomes and quality appraisal method. Primary outcomes of interest will focus on findings reflecting recovery of physical function. Quality of reporting and methodological quality will be appraised using the PRISMA checklist and the Assessment of Multiple Systematic Reviews tool. DISCUSSION: We anticipate the findings from this novel overview of systematic reviews will contribute to the synthesis and interpretation of existing evidence regarding physical rehabilitation interventions and physical recovery in post-critical illness patients across the continuum of recovery. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42015001068.

Early mobilisation in intensive care units in Australia and Scotland: a prospective, observational cohort study examining mobilisation practises and barriers.

INTRODUCTION: Mobilisation of patients in the intensive care unit (ICU) is an area of growing research. Currently, there is little data on baseline mobilisation practises and the barriers to them for patients of all admission diagnoses. METHODS: The objectives of the study were to (1) quantify and benchmark baseline levels of mobilisation in Australian and Scottish ICUs, (2) compare mobilisation practises between Australian and Scottish ICUs and (3) identify barriers to mobilisation in Australian and Scottish ICUs. We conducted a prospective, observational, cohort study with a 4-week inception period. Patients were censored for follow-up upon ICU discharge or after 28 days, whichever occurred first. Patients were included if they were >18 years of age, admitted to an ICU and received mechanical ventilation in the ICU. RESULTS: Ten tertiary ICUs in Australia and nine in Scotland participated in the study. The Australian cohort had a large proportion of patients admitted for cardiothoracic surgery (43.3%), whereas the Scottish cohort had none. Therefore, comparison analysis was done after exclusion of patients admitted for cardiothoracic surgery. In total, 60.2% of the 347 patients across 10 Australian ICUs and 40.1% of the 167 patients across 9 Scottish ICUs mobilised during their ICU stay (p < 0.001). Patients in the Australian cohort were more likely to mobilise than patients in the Scottish cohort (hazard ratio 1.83, 95% confidence interval 1.38-2.42). However, the percentage of episodes of mobilisation where patients were receiving mechanical ventilation was higher in the Scottish cohort (41.1% vs 16.3%, p < 0.001). Sedation was the most commonly reported barrier to mobilisation in both the Australian and Scottish cohorts. Physiological instability and the presence of an endotracheal tube were also frequently reported barriers. CONCLUSIONS: This is the first study to benchmark baseline practise of early mobilisation internationally, and it demonstrates variation in early mobilisation practises between Australia and Scotland.
