Exercise rehabilitation for patients with critical illness: a randomized controlled trial with 12 months of follow-up

Patterns of utilization and effects of hospital-specific factors on physical, occupational, and speech therapy for critically ill patients with acute respiratory failure in the USA: results of a 5-year sample

Background

Timely initiation of physical, occupational, and speech therapy in critically ill patients is crucial to reduce morbidity and improve outcomes. Over a 5-year time interval, we sought to determine the utilization of these rehabilitation therapies in the USA.

Methods

We performed a retrospective cohort study utilizing a large, national administrative database including ICU patients from 591 hospitals. Patients over 18 years of age with acute respiratory failure requiring invasive mechanical ventilation within the first 2 days of hospitalization and for a duration of at least 48 h were included.

Results

A total of 264,137 patients received invasive mechanical ventilation for a median of 4.0 [2.0–8.0] days. Overall, patients spent a median of 5.0 [3.0–10.0] days in the ICU and 10.0 [7.0–16.0] days in the hospital. During their hospitalization, 66.5%, 41.0%, and 33.2% (95% CI = 66.3–66.7%, 40.8–41.2%, 33.0–33.4%, respectively) received physical, occupational, and speech therapy. While on mechanical ventilation, 36.2%, 29.7%, and 29.9% (95% CI = 36.0–36.4%, 29.5–29.9%, 29.7–30.1%) received physical, occupational, and speech therapy. In patients receiving therapy, their first physical therapy session occurred on hospital day 5 [3.0–8.0] and hospital day 6 [4.0–10.0] for occupational and speech therapy. Of all patients, 28.6% (95% CI = 28.4–28.8%) did not receive physical, occupational, or speech therapy during their hospitalization. In a multivariate analysis, patients cared for in the Midwest and at teaching hospitals were more likely to receive physical, occupational, and speech therapy (all P < 0.05). Of patients with identical covariates receiving therapy, there was a median of 61%, 187%, and 70% greater odds of receiving physical, occupational, and speech therapy, respectively, at one randomly selected hospital compared with another (median odds ratio 1.61, 2.87, 1.70, respectively).

Conclusions

Physical, occupational, and speech therapy are not routinely delivered to critically ill patients, particularly while on mechanical ventilation in the USA. The utilization of these therapies varies according to insurance coverage, geography, and hospital teaching status, and at a hospital level.

Introducing early and structured rehabilitation in critical care: A quality improvement project

OBJECTIVES

To assess the potential impact of introducing an already established and effective programme of rehabilitation within a critical care unit in a different organisation.

DESIGN

Fifteen-month prospective before/after quality improvement project.

SETTING

Seven-bed mixed dependency critical care unit.

PARTICIPANTS

209 patients admitted to critical care for ≥4 days.

INTERVENTION

A multi-faceted quality improvement project focussed on changing structure and overcoming local barriers to increase levels of rehabilitation within critical care.

MAIN OUTCOME MEASURE

Proportion of patients mobilised within critical care, time to first mobilise and highest level of mobility achieved within critical care.

RESULTS

Compared to before the quality improvement project, significantly more patients mobilised within critical care (92% vs 73%, p = 0.003). This resulted in a significant reduction in time to 1st mobilisation (2 vs 3.5 days, P < 0.001), particularly for those patients ventilated ≥4 days (3 vs 14 days) and higher mobility scores at the point of critical care discharge (Manchester mobility score 5 vs 4, p = 0.019).

CONCLUSION

The results from this quality improvement project demonstrate the positive impact of introducing a programme of early and structured rehabilitation to a critical care unit within a different organisation. This could provide a framework for introducing similar programmes to other critical care units nationally.

Optimizing Post-Intensive Care Unit Rehabilitation

Survivors of intensive care unit (ICU) admission face unique challenges after hospital discharge. In addition to an increased overall mortality and rates of hospital readmission, patients often experience difficulties in physical functioning, cognition, and mental health, which are collectively termed post-intensive care syndrome. To this date, there are no established strategies to address these deleterious outcomes. A number of studies have examined various unique methods to prevent and treat PICS symptoms, including early physical and occupational therapy, providing post-discharge education, or facilitating routine follow up in post-ICU clinics. These trials have yet to demonstrate any substantial or meaningful effect in post-ICU patients and collectively reinforce the need for further research to identify effective intervention for patients who survive critical illness.

Cost-effectiveness of an integrated 'fast track' rehabilitation service for multi-trauma patients: A non-randomized clinical trial in the Netherlands

Background

Multidisciplinary rehabilitation has been recommended for multi-trauma patients, but there is only low-quality evidence to support its use with these patients. This study examined whether a Supported Fast track multi-Trauma Rehabilitation Service (Fast Track) was cost-effective compared to conventional trauma rehabilitation service (Care As Usual) in patients with multi-trauma from a societal perspective with a one-year follow-up.

Methods

An economic evaluation alongside a prospective, multi-center, non-randomized, controlled clinical study, was conducted in the Netherlands. The primary outcome measure was the Functional Independence Measure (FIM). Generic Quality of Life and Quality Adjusted Life Years (QALYs) of the patients were derived using the Short-form 36 Health Status Questionnaire.

Incremental Cost-Effectiveness Ratios (ICERs) were stated in terms of costs per unit of FIM improvement and costs per QALY. To investigate the uncertainty around the ICERs, non-parametric bootstrapping was used.

Results

In total, 132 patients participated, 65 Fast Track patients and 67 Care As Usual patients. Mean total costs per person were €18,918 higher in the Fast Track group than in the Care As Usual group. Average incremental effects on the FIM were 3.7 points (in favor of the Fast Track group) and the incremental (extra) bootstrapped costs were €19,033, resulting in an ICER for cost per FIM improvement of €5,177. Care As Usual dominated Fast Track in cost per QALY as it gave both higher QALYs and lower costs. All sensitivity analyses attested to the robustness of our results.

Conclusions

This study demonstrated that a multidisciplinary rehabilitation program for multi-trauma patients according to the supported fast track principle is promising but cost-effectiveness evidence remains inconclusive. In terms of functional outcome, Fast Track was more expensive but yielded also more effects compared to the Care As Usual group. Looking at the costs per QALYs, unfavorable ICERs were found. Given the lack of a willingness-to-pay threshold for functional recovery and the relatively short time horizon, it is not possible to draw firm conclusions about the first.

An Early Tailored Approach Is the Key to Effective Rehabilitation in the Intensive Care Unit

OBJECTIVE

To investigate the effectiveness, feasibility, and safety of an evidence-based rehabilitation care pathway in the intensive care unit (ICU) in different patient populations.

DESIGN

Observational prospective cohort study, with retrospective controls.

SETTING

ICUs of a university hospital.

PARTICIPANTS

Patients admitted between April 1, 2015, and June 30, 2015, were compared to a retrospective cohort admitted to the same ICUs during the same 3-month period in 2014. The number of patients studied (N=285) included 152 in the prospective group and 133 in the retrospective group.

INTERVENTIONS

The prospective cohort benefited of a rehabilitation care pathway based on (1) interdisciplinary teamwork; (2) early customized and goal-oriented rehabilitation; (3) daily functional monitoring and treatment revision; (4) agreed discharge policy; and (5) continuity of care. The retrospective cohort underwent usual care.

MAIN OUTCOME MEASURES

Included the following: (1) proportions of patients undergoing rehabilitation team evaluation; (2) latency between patient admission to ICUs and rehabilitation team assessment; (3) proportions of patients undergoing rehabilitation treatment during ICU stay; (4) latency between the patient admission to ICUs and rehabilitation start; (5) ICU stay and total acute hospital stay; and (5) proportion of ventilator-free days out of ICU stay.

RESULTS

The novel rehabilitation care pathway led to (1) an increased proportion of patients receiving rehabilitative assessment (P<.0001); (2) a decreased latency from ICU admission to both rehabilitation team assessment and rehabilitation start (P<.0001); (3) an increased proportion of patients undergoing rehabilitation (P<.0001); (4) a shorter length of stay in ICUs (P<.0001) and in hospital (P=.047); and (5) a shorter mechanical ventilation duration (P<.02). A direct relationship between rehabilitation start latency and ICU length of stay was observed.

CONCLUSIONS

An early, interdisciplinary team approach, providing a customized dynamic planning of physiotherapy programs, increases ventilator-free time and reduces total hospital stay, especially in patients admitted to the ICU after general surgery. This rehabilitation care pathway can be generalized to different geopolitical scenarios, being feasible, safe and cost effective.

Multicentre pilot randomised clinical trial of early in-bed cycle ergometry with ventilated patients

Introduction

Acute rehabilitation in critically ill patients can improve post-intensive care unit (post-ICU) physical function. In-bed cycling early in a patient's ICU stay is a promising intervention. The objective of this study was to determine the feasibility of recruitment, intervention delivery and retention in a multi centre randomised clinical trial (RCT) of early in-bed cycling with mechanically ventilated (MV) patients.

Methods

We conducted a pilot RCT conducted in seven Canadian medical-surgical ICUs. We enrolled adults who could ambulate independently before ICU admission, within the first 4 days of invasive MV and first 7 days of ICU admission. Following informed consent, patients underwent concealed randomisation to either 30 min/day of in-bed cycling and routine physiotherapy (Cycling) or routine physiotherapy alone (Routine) for 5 days/week, until ICU discharge. Our feasibility outcome targets included: accrual of 1-2 patients/month/site; >80% cycling protocol delivery; >80% outcomes measured and >80% blinded outcome measures at hospital discharge. We report ascertainment rates for our primary outcome for the main trial (Physical Function ICU Test-scored (PFIT-s) at hospital discharge).

Results

Between 3/2015 and 6/2016, we randomised 66 patients (36 Cycling, 30 Routine). Our consent rate was 84.6 % (66/78). Patient accrual was (mean (SD)) 1.1 (0.3) patients/month/site. Cycling occurred in 79.3% (146/184) of eligible sessions, with a median (IQR) session duration of 30.5 (30.0, 30.7) min. We recorded 43 (97.7%) PFIT-s scores at hospital discharge and 37 (86.0%) of these assessments were blinded.

Discussion

Our pilot RCT suggests that a future multicentre RCT of early in-bed cycling for MV patients in the ICU is feasible.

Protocol for a mixed-methods exploratory investigation of care following intensive care discharge: the REFLECT study

INTRODUCTION

A substantial number of patients discharged from intensive care units (ICUs) subsequently die without leaving hospital. It is unclear how many of these deaths are preventable. Ward-based management following discharge from ICU is an area that patients and healthcare staff are concerned about. The primary aim of REFLECT (Recovery Following Intensive Care Treatment) is to develop an intervention plan to reduce in-hospital mortality rates in patients who have been discharged from ICU.

METHODS AND ANALYSIS

REFLECT is a multicentre mixed-methods exploratory study examining ward care delivery to adult patients discharged from ICU. The study will be made up of four substudies. Medical notes of patients who were discharged from ICU and subsequently died will be examined using a retrospective case records review (RCRR) technique. Patients and their relatives will be interviewed about their post-ICU care, including relatives of patients who died in hospital following ICU discharge. Staff involved in the care of patients post-ICU discharge will be interviewed about the care of this patient group. The medical records of patients who survived their post-ICU stay will also be reviewed using the RCRR technique. The analyses of the substudies will be both descriptive and use a modified grounded theory approach to identify emerging themes. The evidence generated in these four substudies will form the basis of the intervention development, which will take place through stakeholder and clinical expert meetings.

ETHICS AND DISSEMINATION

Ethical approval has been obtained through the Wales Research and Ethics Committee 4 (17/WA/0107). We aim to disseminate the findings through international conferences, international peer-reviewed journals and social media.

Feasibility, Reliability, Responsiveness, and Validity of the Patient-Reported Functional Scale for the Intensive Care Unit: A Pilot Study

BACKGROUND

Although many performance-based measures assess patients' physical function in intensive care unit (ICU) survivors, to our knowledge, there are no patient-reported ICU rehabilitation-specific measures assessing function. We developed the Patient-Reported Functional Scale-ICU (PRFS-ICU), which measures patients' perceptions of their ability to perform 6 activities (rolling, sitting edge of bed, sit-to-stand and bed-to-chair transfers, ambulation, and stair climbing). Each item is scored from 0 (unable) to 10 (able to perform at pre-ICU level) to a maximum of 60.

OBJECTIVES

Estimate the feasibility, reliability, responsiveness, and validity of the PRFS-ICU.

METHODS

This was a substudy of TryCYCLE, a single-center, prospective cohort examining the safety and feasibility of early in-bed cycling with mechanically ventilated patients (NCT01885442). To determine feasibility, we calculated the number of patients with at least 1 PRFS-ICU assessment during their hospital stay. To assess reliability, 2 raters blinded to each other's assessments administered the PRFS-ICU within 24-hours of each other. We calculated the intraclass correlation coefficient (ICC; 95% confidence interval [CI]), standard error of measurement (SEM, 95% CI), and minimal detectable change (MDC₉₀). To assess validity, we estimated convergent validity of the PRFS-ICU with the Functional Status Score for ICU (FSS-ICU), Medical Research Council Sum Score (MRC-SS), Physical Function Test for ICU (PFIT-s), Katz Index of Independence in Activities of Daily Living (Katz ADLs), and a pooled index using Pearson's correlation coefficient (r, 95% CI).

RESULTS

Feasibility: 20 patients completed a PRFS-ICU assessment. Reliability and responsiveness: 16 patients contributed data. The ICC, SEM, and MDC₉₀ were 0.91 (0.76, 0.97), 4.75 (3.51, 7.35), and 11.04 points, respectively. Validity: 19 patients contributed data and correlations were (r [95% CI]): FSS-ICU (0.40 [-0.14, 0.76]), MRC-SS (0.51 [0.02, 0.80]), PFIT-s (0.43 [-0.13, 0.78]), Katz ADLs (0.53 [0.10, 0.79]), and pooled index (0.48 [-0.14, 0.82]).

CONCLUSIONS

Our pilot work suggests the PRFS-ICU may be a useful tool to assess and monitor patients' perceptions of function over time.

Interventions for the management and prevention of sarcopenia in the critically ill: A systematic review

PURPOSE

In the critically ill, sarcopenia is associated with a variety of adverse outcomes however there is no consensus regarding its management. This study aimed to systematically review the evidence for interventions for the management and prevention of sarcopenia in critically ill patients.

MATERIALS AND METHODS

Bibliographic databases were searched according to pre-specified criteria (PROSPERO-CRD42018086271). Randomised controlled trials (RCTs) investigating interventions to preserve muscle mass and/or function in critically ill patients were included. Two independent authors selected the articles and assessed bias using the Cochrane Risk of Bias Tool.

RESULTS

Twenty-two eligible RCTs were identified comprising 2792 patients. Three main groups of interventions were implemented in these trials: neuromuscular electrical stimulation (NMES), exercise-based and nutritional. Both the interventions and outcomes measured varied significantly between studies. NMES was most frequently studied as an intervention to preserve muscle mass whilst exercise-based treatments were evaluated as interventions to preserve muscle function. There was significant variation in the efficacy of the interventions on sarcopenia markers and secondary outcomes.

CONCLUSIONS

NMES and exercise-based interventions may preserve muscle mass and function in patients with critical illness. There is a lack of consistency seen in the effects of these interventions. Further, large, high quality RCTs are required.

Changes in health-related quality of life after discharge from an intensive care unit: a systematic review

Quality of life after critical illness is becoming increasingly important as survival improves. Various measures have been used to study the quality of life of patients discharged from intensive care. We systematically reviewed validated measures of quality of life and their results. We searched PubMed, CENTRAL, CINAHL, Web of Science and Open Grey for studies of quality of life, measured after discharge from intensive care. We categorised studied populations as: general; restricted to level-3 care or critical care beyond 5 days; and septic patients. We included quality of life measured at any time after hospital discharge. We identified 48 studies. Thirty-one studies used the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) and 19 used the EuroQol-5D (EQ-5D); eight used both and nine used alternative validated measures. Follow-up rates ranged from 26-100%. Quality of life after critical care was worse than for age- and sex-matched populations. Quality of life improved for one year after hospital discharge. The aspects of life that improved most were physical function, physical role, vitality and social function. However, these domains were also the least likely to recover to population norms as they were more profoundly affected by critical illness.

Physical rehabilitation interventions in the intensive care unit: a scoping review of 117 studies

BACKGROUND

Physical rehabilitation (PR) interventions in the intensive care unit (ICU) can improve patients' functional outcomes, yet systematic reviews identified discordant effects and poor reporting. We conducted a scoping review to determine the extent of ICU PR interventions and how they were reported and measured.

METHODS

We searched five databases from inception to December 2016 for prospective studies evaluating adult ICU PR interventions. Two independent reviewers screened titles, abstracts, and full texts for inclusion. We assessed completeness of reporting using the Consolidated Standards of Reporting Trials, Strengthening the Reporting of Observational Studies in Epidemiology, or Standards for Quality Improvement Reporting Excellence guidelines, as appropriate. For planned PR interventions, we evaluated reporting with the Consensus on Exercise Reporting Template (CERT) and assessed intervention and control groups separately. We calculated completeness of reporting scores for each study; scores represented the proportion of reported items. We compared reporting between groups using Kruskal-Wallis with Bonferroni corrections and t tests, α = 0.05.

RESULTS

We screened 61,774 unique citations, reviewed 1429 full-text publications, and included 117: 39 randomized trials, 30 case series, 9 two-group comparison, 14 before-after, and 25 cohort. Interventions included neuromuscular electrical stimulation (NMES) (14.5%), passive/active exercises (15.4%), cycling (6.8%), progressive mobility (32.5%), and multicomponent (29.9%). The median (first,third quartiles) study reporting score was 75.9% (62.5, 86.7) with no significant differences between reporting guidelines. Of 87 planned intervention studies, the median CERT score was 55.6%(44.7,75.0); cycling had the highest (85.0%(62.2,93.8)), and NMES and multicomponent the lowest (50.0% (39.5, 70.3) and 50.0% (41.5, 58.8), respectively) scores. Authors reported intervention groups better than controls (p < 0.001).

CONCLUSIONS

We identified important reporting deficiencies in ICU PR interventions, limiting clinical implementation and future trial development.

Incidence and risk factors for alopecia in survivors of critical illness: A multi-centre observational study

PURPOSE

To investigate the incidence, nature and risk factors for patient-reported alopecia in survivors of critical illness.

MATERIALS AND METHODS

A multi-centre, mixed methods observational study in the intensive care units (ICU) of ten hospitals in Wales. All patients with an ICU stay of 5 days or more, able to give consent were included. Demographic variables and risk factors were collected. A pre-designed survey was completed at three months post-ICU discharge. Statistical analysis included numbers and percentages (categorical variables) and medians and interquartile ranges (continuous variables). Comparisons between patients with and without alopecia were made using Fisher's Exact test (categorical variables) and Mann Whitney U test (continuous variables). Multivariate logistic regression analysis was used to determine the risk factors for alopecia.

RESULTS

The survey was completed by 123 patients with alopecia reported in 44 (36%) patients. The only risk factor for alopecia on analysis was sepsis / septic shock (p < .001; OR: 5.1, 95%CI: 2.1-12.4).

CONCLUSIONS

Limited research exists examining the incidence, nature and risk factors for patient-reported alopecia in adult survivors of critical illness. The results of this study highlight the need to discuss the potential for alopecia with survivors of critical illness, who had sepsis / septic shock.

Effects of early, combined endurance and resistance training in mechanically ventilated, critically ill patients: A randomised controlled trial

INTRODUCTION

Neuromuscular weakness resulting in severe functional impairment is common in critical care survivors. This study aimed to evaluate effects of an early progressive rehabilitation intervention in mechanically ventilated adults at risk.

METHODS

This was a parallel, two-arm, assessor-blinded, randomised controlled trial with 6-months follow-up that was conducted in a mixed ICU of an academic centre in Switzerland. Previously independent, mechanically ventilated, critically ill adults with expected critical care stay ≥72 hours (n = 115) were randomised to a control group receiving standard physiotherapy including early mobilisation or to an experimental group with early endurance and resistance training combined with mobilisation. Primary endpoints were functional capacity (6-Minute Walk Distance) and functional independence (Functional Independence Measure) at hospital discharge. Secondary endpoints including muscle strength were assessed at critical care discharge. Safety was monitored closely by standard monitoring and predefined adverse events.

RESULTS

Physiotherapy started within 48 hours of critical care admission while 97% of participants were still ventilated and 68% on inotropes. Compared to the control group (n = 57), the experimental group (n = 58) received significantly more physiotherapy (sessions: 407 vs 377, p<0.001; time/session: 25min vs 18min, p<0.001) and had less days with sedation (p<0.001). Adverse events were rare (0.6%) and without consequences. There were no significant between-group differences in 6-Minute Walk Distance (experimental 123m (IQR 25-280) vs control 100m (IQR 0-300); p = 0.542) or functional independence (98 (IQR 66-119) vs 98 (IQR 18-115); p = 0.308). Likewise, no differences were found for the secondary outcomes, except a trend towards improved mental health in the experimental group after 6 months (84 (IQR 68-88) vs 70 (IQR 64-76); p = 0.023).

CONCLUSIONS

Early endurance and resistance training in mechanically ventilated, intensive care patients does not improve functional capacity or independence at hospital discharge compared to early standard physiotherapy but may improve mental health 6-months after critical care discharge.

Determinants of Quality of Life and Return to Work Following Acute Respiratory Distress Syndrome

BACKGROUND

Acute respiratory distress syndrome (ARDS) in adults is a consequence of lung damage caused by either pulmonary or extrapulmonary disease. Survivors often suffer from an impaired health-related quality of life (HRQoL), mental and physical impairments, and persistent inability to work.

METHODS

In this systematic review of the literature, we consider the determinants of HRQoL and return to work (RtW). 24 observational studies showing a statistical association between one or more determinants and HRQoL or RtW were included. Because of the heterogeneity of these studies, no statistical aggregation of the individual effect estimates was carried out; instead, the results are summarized descriptively.

RESULTS

Psychopathological manifestations, in particular, are associated with impaired quality of life. In contrast, many care- and disease-related determinants had only small, non-significant effects on HRQoL and RtW. The onesecond capacity was found in all studies to be positively associated with the HRQoL. ARDS induced by sepsis seems to be a risk factor for a lower HRQoL in comparison to ARDS of other causes. A synthesis of the evidence is impeded both by the high level of heterogeneity of studies and by the high risk of selection bias in all studies.

CONCLUSION

The identification of determinants of impaired quality of life after ARDS is essential for the assessment of clinically relevant interventions. In multiple studies, major significant effects were only observed when determinants the content of which was closely related to the scales of the HRQoL instruments were measured at the same time as the HRQoL.

Avoiding Respiratory and Peripheral Muscle Injury During Mechanical Ventilation: Diaphragm-Protective Ventilation and Early Mobilization

Both limb muscle weakness and respiratory muscle weakness are exceedingly common in critically ill patients. Respiratory muscle weakness prolongs ventilator dependence, predisposing to nosocomial complications and death. Limb muscle weakness persists for months after discharge from intensive care and results in poor long-term functional status and quality of life. Major mechanisms of muscle injury include critical illness polymyoneuropathy, sepsis, pharmacologic exposures, metabolic derangements, and excessive muscle loading and unloading. The diaphragm may become weak because of excessive unloading (leading to atrophy) or because of excessive loading (either concentric or eccentric) owing to insufficient ventilator assistance.

Metabolic phenotype of skeletal muscle in early critical illness

OBJECTIVES

To characterise the sketetal muscle metabolic phenotype during early critical illness.

METHODS

Vastus lateralis muscle biopsies and serum samples (days 1 and 7) were obtained from 63 intensive care patients (59% male, 54.7±18.0 years, Acute Physiology and Chronic Health Evaluation II score 23.5±6.5).

MEASUREMENTS AND MAIN RESULTS

From day 1 to 7, there was a reduction in mitochondrial beta-oxidation enzyme concentrations, mitochondrial biogenesis markers (PGC1α messenger mRNA expression (-27.4CN (95% CI -123.9 to 14.3); n=23; p=0.025) and mitochondrial DNA copy number (-1859CN (IQR -5557-1325); n=35; p=0.032). Intramuscular ATP content was reduced compared tocompared with controls on day 1 (17.7mmol/kg /dry weight (dw) (95% CI 15.3 to 20.0) vs. 21.7 mmol/kg /dw (95% CI 20.4 to 22.9); p<0.001) and decreased over 7 days (-4.8 mmol/kg dw (IQR -8.0-1.2); n=33; p=0.001). In addition, the ratio of phosphorylated:total AMP-K (the bioenergetic sensor) increased (0.52 (IQR -0.09-2.6); n=31; p<0.001). There was an increase in intramuscular phosphocholine (847.2AU (IQR 232.5-1672); n=15; p=0.022), intramuscular tumour necrosis factor receptor 1 (0.66 µg (IQR -0.44-3.33); n=29; p=0.041) and IL-10 (13.6 ng (IQR 3.4-39.0); n=29; p=0.004). Serum adiponectin (10.3 µg (95% CI 6.8 to 13.7); p<0.001) and ghrelin (16.0 ng/mL (IQR -7-100); p=0.028) increased. Network analysis revealed a close and direct relationship between bioenergetic impairment and reduction in muscle mass and between intramuscular inflammation and impaired anabolic signaling. ATP content and muscle mass were unrelated to lipids delivered.

CONCLUSIONS

Decreased mitochondrial biogenesis and dysregulated lipid oxidation contribute to compromised skeletal muscle bioenergetic status. In addition, intramuscular inflammation was associated with impaired anabolic recovery with lipid delivery observed as bioenergetically inert. Future clinical work will focus on these key areas to ameliorate acute skeletal muscle wasting.

Recent evidence on early mobilization in critical-Ill patients

PURPOSE OF REVIEW

To examine the benefits of early mobilization and summarize the results of most recent clinical studies examining early mobilization in critically ill patients followed by a presentation of recent developments in the field.

RECENT FINDINGS

Early mobilization of ICU patients, defined as mobilization within 72 h of ICU admission, is still uncommon. In medical and surgical critically ill patients, mobilization is well tolerated even in intubated patients. In neurocritical care, evidence to support early mobilization is either lacking (aneurysmal subarachnoid hemorrhage), or the results are inconsistent (e.g. stroke). Successful implementation of early mobilization requires a cultural change; preferably based on an interprofessional approach with clearly defined responsibilities and including a mobilization scoring system. Although the evidence for the majority of the technical tools is still limited, the use of a bed cycle ergometer and a treadmill with strap system has been promising in smaller trials.

SUMMARY

Early mobilization is well tolerated and feasible, resulting in improved outcomes in surgical and medical ICU patients. Implementation of early mobilization can be challenging and may need a cultural change anchored in an interprofessional approach and integrated in a patient-centered bundle. Scoring systems should be integrated to define daily goals and used to verify patients' achievements or identify barriers immediately.

Rehabilitation and early mobilization in the critical patient: systematic review

[Purpose] To review the literature that examines rehabilitation and early mobilization and that involves different practices (effects of interventions) for the critically ill patient. [Materials and Methods] A PRISMA-Systematic review has been conducted based on different data sources: Biblioteca Virtual en Salud, CINHAL, Pubmed, Scopus, and Web of Science were used to identify randomized controlled trials, crossover trials, and case-control studies. [Results] Eleven studies were included. Early rehabilitation had no significant effect on the length of stay and number of cases of Intensive Care Unit Acquired Weaknesses. However, early rehabilitation had a significant effect on the functional status, muscle strength, mechanical ventilation duration, walking ability at discharge, and health quality of life. [Conclusion] Rehabilitation and early mobilization are associated with an increased probability of walking more distance at discharge. Early rehabilitation is associated with an increase in functional capacity and muscle strength, an improvement in walking distance and better perception of the health-related quality of life. Cycloergometer and electrical stimulation can be used to maintain muscle strength. Further research is needed to establish stronger evidences.

Engaging Families in Rehabilitation of People Who Are Critically Ill: An Underutilized Resource

Rehabilitation of people who are critically ill has received increased attention in recent years, although this has not extended to specifically facilitating family involvement. Engaging families in the rehabilitation arc has the potential to optimize outcomes. Likely benefits include redirecting family psychological distress into an active participatory role, humanizing the patient illness and recovery experience, and supporting staff and the health care system beyond the constraints of therapy time. This viewpoint explores why families should be engaged in critical care rehabilitation, gives an overview of the evidence for family participation in bedside care, and provides practical implementation strategies and signpost areas for future research.

Commencing Out-of-Bed Rehabilitation in Critical Care-What Influences Clinical Decision-Making?

OBJECTIVES

To develop a decision tree that objectively identifies the most discriminative variables in the decision to provide out-of-bed rehabilitation, measure the effect of this decision and to identify the factors that intensive care unit (ICU) practitioners think most influential in that clinical decision.

DESIGN

A prospective 3-part study: (1) consensus identification of influential factors in mobilization via survey; (2) development of an early rehabilitation decision tree; (3) measurement of practitioner mobilization decision-making. Treating practitioners of patients expected to stay >96 hours were asked if they would provide out-of-bed rehabilitation and rank factors that influenced this decision from an a priori defined list developed from a literature review and expert consultation.

SETTING

Four tertiary metropolitan ICUs.

PARTICIPANTS

Practitioners (ICU medical, nursing, and physiotherapy staff) (N=507).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

A decision tree was constructed using binary recursive partitioning to determine the factor that best classified patients suitable for out-of-bed rehabilitation. Descriptive statistics were used to describe practitioner and patient samples as well as patient adverse events associated with out-of-bed rehabilitation and the factors prioritized by ICU practitioners.

RESULTS

There were 1520 practitioner decisions representing 472 individual patient decisions. Practitioners classified patients suitable for out-of-bed rehabilitation on 149 occasions and not suitable on 323 occasions. Decision tree analysis showed the presence of an endotracheal tube (ETT) and sedation state were the only discriminative variables that predicted patient suitability for rehabilitation. In contrast, medical staff and nurses reported that ventilator status was the most influential factor in their decision not to provide rehabilitation while physiotherapists ranked sedation most highly. The presence of muscle weakness did not inform the decision to provide rehabilitation.

CONCLUSION

These results confirm previous observational reports that the presence of an ETT remains a major obstacle to the provision of rehabilitation for critically ill patients. Despite rehabilitation being effective for improving muscle strength, the presence of muscle weakness did not influence the decision to provide rehabilitation.

Physical Rehabilitation Core Outcomes In Critical illness (PRACTICE): protocol for development of a core outcome set

Background

Existing data on physical rehabilitation interventions in critical illness are challenged by outcome heterogeneity that limits data synthesis and translation of research findings into clinical practice. This protocol describes the PRACTICE study to develop a core outcome set (COS) for trials of physical rehabilitation interventions delivered across the continuum of a patient’s recovery from the intensive care unit until reintegration in the community following hospital discharge.

Methods

Mixed methods will be used including: systematic reviews of quantitative and qualitative literature; qualitative interviews with patients and caregivers; a modified Delphi consensus process with researcher, clinician and patient/caregiver stakeholder groups; and consensus meetings for ratification of findings, resolving uncertainty, or developing an action plan for COS implementation.

Discussion

The PRACTICE COS will inform relevant stakeholders about important outcomes regarding physical rehabilitation in critical illness, and may enhance the future design and conduct of trials in this area.

Appetite during the recovery phase of critical illness: a cohort study

BACKGROUND/OBJECTIVES

Reduced appetite is a recognised physiological symptom in survivors of critical illness. While reduced appetite has been reported by patients after intensive care unit (ICU) discharge, quantification using visual analogue scales (VAS) has not been previously performed, and follow-up duration has been limited. We aimed to describe appetite scores in ICU survivors during the first 3 months after ICU discharge and explore association with systemic inflammation.

SUBJECTS/METHODS

Secondary analysis of data collected in a complex rehabilitation intervention trial (RECOVER). A subgroup of 193 patients provided specific consent for inclusion in the blood sampling sub-study during consent for the main study. We studied appetite using a VAS; serum C-reactive protein (CRP); interleukin-1β and interleukin-6 (IL-1β and IL-6); and hand-grip strength.

RESULTS

Median (interquartile range) score on 0-10 appetite VAS was 4.3 (2.0-6.5) 1 week after ICU discharge, improving to 7.1 (4.6-8.9) by 3 months (mean difference 1.7 (0.9-2.4), p < 0.01). Number of days spent in an acute hospital following an intensive care stay was associated with poorer appetite scores (p = 0.03). CRP concentration and appetite were significantly associated at 1 week after ICU discharge (p = 0.01), but not at 3 months after ICU discharge (p = 0.67).

CONCLUSIONS

ICU survivors experience reduced appetite during the acute recovery phase of critical illness that could impact on nutritional recovery and this was associated with CRP concentration 1 week after ICU discharge.

Early rehabilitation to prevent postintensive care syndrome in patients with critical illness: a systematic review and meta-analysis

INTRODUCTION

We examined the effectiveness of early rehabilitation for the prevention of postintensive care syndrome (PICS), characterised by an impaired physical, cognitive or mental health status, among survivors of critical illness.

METHODS

We performed a systematic literature search of several databases (Medline, Embase and Cochrane Central Register of Controlled Trials) and a manual search to identify randomised controlled trials (RCTs) comparing the effectiveness of early rehabilitation versus no early rehabilitation or standard care for the prevention of PICS. The primary outcomes were short-term physical-related, cognitive-related and mental health-related outcomes assessed during hospitalisation. The secondary outcomes were the standardised, long-term health-related quality of life scores (EuroQol 5 Dimension (EQ5D) and the Medical Outcomes Study 36-Item Short Form Health Survey Physical Function Scale (SF-36 PF)). We used the Grading of Recommendations Assessment, Development and Evaluation approach to rate the quality of evidence (QoE).

RESULTS

Six RCTs selected from 5105 screened abstracts were included. Early rehabilitation significantly improved short-term physical-related outcomes, as indicated by an increased Medical Research Council scale score (standardised mean difference (SMD): 0.38, 95% CI 0.10 to 0.66, p=0.009) (QoE: low) and a decreased incidence of intensive care unit-acquired weakness (OR 0.42, 95% CI 0.22 to 0.82, p=0.01, QoE: low), compared with standard care or no early rehabilitation. However, the two groups did not differ in terms of cognitive-related delirium-free days (SMD: -0.02, 95% CI -0.23 to 0.20, QoE: low) and the mental health-related Hospital Anxiety and Depression Scale score (OR: 0.79, 95% CI 0.29 to 2.12, QoE: low). Early rehabilitation did not improve the long-term outcomes of PICS as characterised by EQ5D and SF-36 PF.

CONCLUSIONS

Early rehabilitation improved only short-term physical-related outcomes in patients with critical illness. Additional large RCTs are needed.

Evaluation of the description of active mobilisation protocols for mechanically ventilated patients in the intensive care unit: A systematic review of randomized controlled trials

BACKGROUND

The complete description of exercise interventions is essential to allow for the replication of clinical trials and to the correct application in clinical practice.

OBJECTIVES

The aim of this review was to evaluate of the description of the active mobilisation protocols in patients on invasive mechanical ventilation at intensive care units (ICU).

METHODS

Systematic review of randomised controlled trials (RCTs) using the Consensus on Exercise Reporting Template.

RESULTS

We identified 16 RCTs (n = 1,850). None sufficiently described the intervention for all items required for replication. The frequency, intensity, time, volume, and progression of active mobilisation as well as other important components of the intervention such as the instructor's qualifications/expertise, the types and incidence of adverse events, and the adherence to the exercise intervention were not adequately reported.

CONCLUSION

Active mobilisation interventions were only incompletely described in RCTs, which can compromise replication in both, clinical and research settings.

Mobilisation is feasible in intensive care patients receiving vasoactive therapy: An observational study

BACKGROUND

Mobilisation of intensive care unit (ICU) patients reduces ICU-acquired weakness and is associated with better functional outcomes. However, the prevalence of mobilisation of ICU patients remains low. A known barrier to mobilisation is haemodynamic instability, frequently with patients requiring vasoactive therapy. There is a lack of published data to guide clinicians about the safety and feasibility of mobilising patients receiving vasoactive therapy.

OBJECTIVES

To describe our mobilisation practice in ICU patients receiving vasoactive therapy and identify factors associated with mobilisation and adverse events.

METHODS

Retrospective cohort study of patients undergoing vasoactive therapy in a 31-bed tertiary ICU (October-December, 2016). Details of vasoactive drug dosage, mobilisation, and adverse events were extracted from databases, including mobilisation intensity (ICU Mobility Scale [IMS]). Two generalised linear mixed models were used: first, to describe factors associated with mobilisation and second, to describe factors associated with adverse events during mobilisation, adjusting for age, gender, and acute physiology and chronic health evaluation II score as co-variates.

RESULTS

In 119 patients undergoing vasoactive therapy on 371 cumulative vasoactive days, 195 mobilisation episodes occurred (37.5% of vasoactive days). Low (76.8%) and moderate (13.7%) dose vasoactive therapies were associated with a higher probability of mobilisation relative to high (9.4%) dose therapy (odds ratio = 5.50, 95% confidence interval = 2.23-13.59 and odds ratio = 2.50, 95% confidence interval = 0.95-6.59, respectively). For patients who mobilised on vasoactive therapy (n = 72), maximum mobilisation intensity was low (IMS = 1-2) in 31%, moderate (IMS = 3-5) in 51%, and high (IMS = 6-10) in 18% of vasoactive days. While no serious adverse events occurred, there were 14 occurrences of reversible hypotension requiring transient escalation of vasoactive therapy (7.3%), associated with lower mean arterial pressure (p = 0.001).

CONCLUSION

In our ICU, patients mobilised on approximately one-third of vasoactive days. Clinicians should anticipate a higher risk of hypotension during mobilisation in patients receiving vasoactive therapy, which may require transient escalation of vasoactive therapy.

Should We Prescribe More Protein to Critically Ill Patients?

In the context of critical illness, evidence suggests that exogenous protein/amino acid supplementation has the potential to favorably impact whole-body protein balance. Whether this translates into retention of muscle, greater muscle strength, and improved survival and physical recovery of critically ill patients remains uncertain. The purpose of this brief commentary is to provide an overview of the clinical evidence for and against increasing protein doses and to introduce two new trials that will add considerably to our evolving understanding of protein requirements in the critically ill adult patient.

Supervised exercise rehabilitation in survivors of critical illness: A randomised controlled trial

Objectives

To investigate the impact of a six-week supervised exercise programme on cardiopulmonary fitness, balance, muscle strength and anxiety and depression in patients who have been discharged home from hospital following an intensive care unit length of stay of greater than 48 h. To investigate patients' perceptions of a six-week supervised exercise programme delivered at three months post hospital discharge.

Design

A single centre parallel, randomised controlled trial.

Setting

Outpatient department of a university teaching hospital in the UK.

Participants

Sixty adult survivors of critical illness, at three months post-hospital discharge.

Intervention

A six-week individually prescribed and supervised exercise program, with associated advice to home exercise modification. Twice weekly exercise sessions were individualised to participant's functional status and included cardiopulmonary, balance and strengthening exercises. Follow up at seven weeks, six months and 12 months.

Outcome measures

Six-Minute Walk Test, BERG balance test, grip strength and Hospital Anxiety and Depression Scale. A pre-designed survey was used to explore patient perceptions of the programme.

Results

Sixty participants (n = 30 received allocated programme in both control and treatment groups) were randomised. Loss to follow up resulted in n = 34 participants for intention to treat analysis at 12 months follow up (leaving n = 19 in control group, n = 15 in treatment group). Median participant age at enrolment was 62 years (interquartile range: 49-72), with a median intensive care unit length of stay of nine days (interquartile range: 4-17). No significant differences were found for the Six-Minute Walk Test at any time point (p > 0.05). Anxiety levels and balance were significantly improved in the treatment group at 12 months (p = 0.006 and p = 0.040, respectively).

Conclusions

Further research is needed into appropriate interventions and outcome measures, target patient populations and timing of such intervention post-hospital discharge.

Early intervention (mobilization or active exercise) for critically ill adults in the intensive care unit

BACKGROUND

Survivors of critical illness often experience a multitude of problems that begin in the intensive care unit (ICU) or present and continue after discharge. These can include muscle weakness, cognitive impairments, psychological difficulties, reduced physical function such as in activities of daily living (ADLs), and decreased quality of life. Early interventions such as mobilizations or active exercise, or both, may diminish the impact of the sequelae of critical illness.

OBJECTIVES

To assess the effects of early intervention (mobilization or active exercise), commenced in the ICU, provided to critically ill adults either during or after the mechanical ventilation period, compared with delayed exercise or usual care, on improving physical function or performance, muscle strength and health-related quality of life.

SEARCH METHODS

We searched CENTRAL, MEDLINE, Embase and CINAHL. We searched conference proceedings, reference lists of retrieved articles, databases of trial registries and contacted experts in the field on 31 August 2017. We did not impose restrictions on language or location of publications.

SELECTION CRITERIA

We included all randomized controlled trials (RCTs) or quasi-RCTs that compared early intervention (mobilization or active exercise, or both), delivered in the ICU, with delayed exercise or usual care delivered to critically ill adults either during or after the mechanical ventilation period in the ICU.

DATA COLLECTION AND ANALYSIS

Two researchers independently screened titles and abstracts and assessed full-text articles against the inclusion criteria of this review. We resolved any disagreement through discussion with a third review author as required. We presented data descriptively using mean differences or medians, risk ratios and 95% confidence intervals. A meta-analysis was not possible due to the heterogeneity of the included studies. We assessed the quality of evidence with GRADE.

MAIN RESULTS

We included four RCTs (a total of 690 participants), in this review. Participants were adults who were mechanically ventilated in a general, medical or surgical ICU, with mean or median age in the studies ranging from 56 to 62 years. Admitting diagnoses in three of the four studies were indicative of critical illness, while participants in the fourth study had undergone cardiac surgery. Three studies included range-of-motion exercises, bed mobility activities, transfers and ambulation. The fourth study involved only upper limb exercises. Included studies were at high risk of performance bias, as they were not blinded to participants and personnel, and two of four did not blind outcome assessors. Three of four studies reported only on those participants who completed the study, with high rates of dropout. The description of intervention type, dose, intensity and frequency in the standard care control group was poor in two of four studies.Three studies (a total of 454 participants) reported at least one measure of physical function. One study (104 participants) reported low-quality evidence of beneficial effects in the intervention group on return to independent functional status at hospital discharge (59% versus 35%, risk ratio (RR) 1.71, 95% confidence interval (CI) 1.11 to 2.64); the absolute effect is that 246 more people (95% CI 38 to 567) per 1000 would attain independent functional status when provided with early mobilization. The effects on physical functioning are uncertain for a range measures: Barthel Index scores (early mobilization: median 75 control: versus 55, low quality evidence), number of ADLs achieved at ICU (median of 3 versus 0, low quality evidence) or at hospital discharge (median of 6 versus 4, low quality evidence). The effects of early mobilization on physical function measured at ICU discharge are uncertain, as measured by the Acute Care Index of Function (ACIF) (early mobilization mean: 61.1 versus control: 55, mean difference (MD) 6.10, 95% CI -11.85 to 24.05, low quality evidence) and the Physical Function ICU Test (PFIT) score (5.6 versus 5.4, MD 0.20, 95% CI -0.98 to 1.38, low quality evidence). There is low quality evidence that early mobilization may have little or no effect on physical function measured by the Short Physical Performance Battery score at ICU discharge from one study of 184 participants (mean 1.6 in the intervention group versus 1.9 in usual care, MD -0.30, 95% CI -1.10 to 0.50), or at hospital discharge (MD 0, 95% CI -1.00 to 0.90). The fourth study, which examined postoperative cardiac surgery patients did not measure physical function as an outcome.Adverse effects were reported across the four studies but we could not combine the data. Our certainty in the risk of adverse events with either mobilization strategy is low due to the low rate of events. One study reported that in the intervention group one out of 49 participants (2%) experienced oxygen desaturation less than 80% and one of 49 (2%) had accidental dislodgement of the radial catheter. This study also found cessation of therapy due to participant instability occurred in 19 of 498 (4%) of the intervention sessions. In another study five of 101 (5%) participants in the intervention group and five of 109 (4.6%) participants in the control group had postoperative pulmonary complications deemed to be unrelated to intervention. A third study found one of 150 participants in the intervention group had an episode of asymptomatic bradycardia, but completed the exercise session. The fourth study reported no adverse events.

AUTHORS' CONCLUSIONS

There is insufficient evidence on the effect of early mobilization of critically ill people in the ICU on physical function or performance, adverse events, muscle strength and health-related quality of life at this time. The four studies awaiting classification, and the three ongoing studies may alter the conclusions of the review once these results are available. We assessed that there is currently low-quality evidence for the effect of early mobilization of critically ill adults in the ICU due to small sample sizes, lack of blinding of participants and personnel, variation in the interventions and outcomes used to measure their effect and inadequate descriptions of the interventions delivered as usual care in the studies included in this Cochrane Review.

The Association of Frailty With Post-ICU Disability, Nursing Home Admission, and Mortality: A Longitudinal Study

BACKGROUND

Frailty is a strong indicator of vulnerability among older persons, but its association with ICU outcomes has not been evaluated prospectively (ie, with objective measurements obtained prior to ICU admission). Our objective was to prospectively evaluate the relationship between frailty and post-ICU disability, incident nursing home admission, and death.

METHODS

The parent cohort included 754 adults aged ≥ 70 years, who were evaluated monthly for disability in 13 functional activities and every 18 months for frailty (1998-2014). Frailty was assessed using the Fried index, where frailty, prefrailty, and nonfrailty were defined, respectively, as at least three, one or two, and zero criteria (of five). The analytic sample included 391 ICU admissions.

RESULTS

The mean age was 84.0 years. Frailty and prefrailty were present prior to 213 (54.5%) and 140 (35.8%) of the 391 admissions, respectively. Relative to nonfrailty, frailty was associated with 41% greater disability over the 6 months following a critical illness (adjusted risk ratio, 1.41; 95% CI, 1.12-1.78); prefrailty conferred 28% greater disability (adjusted risk ratio, 1.28; 95% CI, 1.01-1.63). Frailty (odds ratio, 3.52; 95% CI, 1.23-10.08), but not prefrailty (odds ratio, 2.01; 95% CI, 0.77-5.24), was associated with increased nursing home admission. Each one-point increase in frailty count (range, 0-5) was associated with double the likelihood of death (hazard ratio, 2.00; 95% CI, 1.33-3.00) through 6 months of follow-up.

CONCLUSIONS

Pre-ICU frailty status was associated with increased post-ICU disability and new nursing home admission among ICU survivors, and death among all admissions. Pre-ICU frailty status may provide prognostic information about outcomes after a critical illness.

Practice Recommendations for Early Mobilization in Critically Ill Children

Prolonged immobility is associated with significant short- and long-term morbidities in critically ill adults and children. The majority of critically ill children remain immobilized while in the pediatric intensive care unit (PICU) due to limited awareness of associated morbidities, lack of comfort and knowledge on how to mobilize critically ill children, and the lack of pediatric-specific practice guidelines. The objective of this article was to develop consensus practice recommendations for safe, early mobilization (EM) in critically ill children. A group of 10 multidisciplinary experts with clinical and methodological expertise in physical rehabilitation, EM, and pediatric critical care collaborated to develop these recommendations. First, a systematic review was conducted to evaluate existing evidence on EM in children. Using an iterative process, the working document was circulated electronically to panel members until the group reached consensus. The group agreed that the overall goals of mobilization are to reduce PICU morbidities and optimize recovery. EM should therefore not be instituted in isolation but as part of a rehabilitation care bundle. Mobilization should not be delayed, but its appropriateness and safety should be assessed early. Increasing levels of physical activity should be individualized for each patient with the goal of achieving the highest level of functional mobility that is developmentally appropriate, for increasing durations, daily. We developed a system-based set of clinical safety criteria and a checklist to ensure the safety of mobilization in critically ill children. Although there is a paucity of pediatric evidence on the efficacy of EM, there is ample evidence that prolonged bed rest is harmful and should be avoided. These EM practice recommendations were developed to educate clinicians, encourage safe practices, reduce PICU-acquired morbidities, until future pediatric research provides evidence on effective rehabilitation interventions and how best to implement these in critically ill children.

Long-term recovery following critical illness in an Australian cohort

BACKGROUND

Almost all data on 5-year outcomes for critical care survivors come from North America and Europe. The aim of this study was to investigate long-term mortality, physical function, psychological outcomes and health-related quality of life in a mixed intensive care unit cohort in Australia.

METHODS

This longitudinal study evaluated 4- to 5-year outcomes. Physical function (six-minute walk test) and health-related quality of life (Short Form 36 Version 2) were compared to 1-year outcomes and population norms. New psychological data (Center for Epidemiological Studies-Depression, Impact of Events Scale) was collected at follow-up.

RESULTS

Of the 150 participants, 66 (44%) patients were deceased by follow-up. Fifty-six survivors were included with a mean (SD) age of 64 (14.2). Survivors' mean (SD) six-minute walk distance increased between 1 and 4 to 5 years (465.8 m (148.9) vs. 507.5 m (118.2)) (mean difference = - 24.5 m, CI - 58.3, 9.2, p = 0.15). Depressive symptoms were low: median (IQR) score of 7.0 (1.0-15.0). The mean level of post-traumatic stress symptoms was low-median (IQR) score of 1.0 (0-11.0)-with only 9 (16%) above the threshold for potentially disordered symptoms. Short-Form 36 Physical and Mental Component Scores did not change between 1 and 4 to 5 years (46.4 (7.9) vs. 46.7 (8.1) and 48.8 (13) vs. 48.8 (11.1)) and were within a standard deviation of normal.

CONCLUSIONS

Outcomes of critical illness are not uniform across nations. Mortality was increased in this cohort; however, survivors achieved a high level of recovery for physical function and health-related quality of life with low psychological morbidity at follow-up.

TRIAL REGISTRATION

The trial was registered with the Australian New Zealand Clinical Trials Registry ACTRN12605000776606.

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016)

BACKGROUND AND PURPOSE

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016), a Japanese-specific set of clinical practice guidelines for sepsis and septic shock created jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in February 2017 and published in the Journal of JSICM, [2017; Volume 24 (supplement 2)] 10.3918/jsicm.24S0001 and Journal of Japanese Association for Acute Medicine [2017; Volume 28, (supplement 1)] http://onlinelibrary.wiley.com/doi/10.1002/jja2.2017.28.issue-S1/issuetoc.This abridged English edition of the J-SSCG 2016 was produced with permission from the Japanese Association of Acute Medicine and the Japanese Society for Intensive Care Medicine.

METHODS

Members of the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine were selected and organized into 19 committee members and 52 working group members. The guidelines were prepared in accordance with the Medical Information Network Distribution Service (Minds) creation procedures. The Academic Guidelines Promotion Team was organized to oversee and provide academic support to the respective activities allocated to each Guideline Creation Team. To improve quality assurance and workflow transparency, a mutual peer review system was established, and discussions within each team were open to the public. Public comments were collected once after the initial formulation of a clinical question (CQ) and twice during the review of the final draft. Recommendations were determined to have been adopted after obtaining support from a two-thirds (> 66.6%) majority vote of each of the 19 committee members.

RESULTS

A total of 87 CQs were selected among 19 clinical areas, including pediatric topics and several other important areas not covered in the first edition of the Japanese guidelines (J-SSCG 2012). The approval rate obtained through committee voting, in addition to ratings of the strengths of the recommendation, and its supporting evidence were also added to each recommendation statement. We conducted meta-analyses for 29 CQs. Thirty-seven CQs contained recommendations in the form of an expert consensus due to insufficient evidence. No recommendations were provided for five CQs.

CONCLUSIONS

Based on the evidence gathered, we were able to formulate Japanese-specific clinical practice guidelines that are tailored to the Japanese context in a highly transparent manner. These guidelines can easily be used not only by specialists, but also by non-specialists, general clinicians, nurses, pharmacists, clinical engineers, and other healthcare professionals.

Advances in cardiorespiratory physiotherapy and their clinical impact

INTRODUCTION

Cardiorespiratory physiotherapy is an evidence-based practice that has evolved alongside changes in medical and surgical management, analgesia, the ageing society and increasing comorbidities of our patient populations. Continued research provides the profession with the ability to adapt to meet the changing patient and community needs. Areas covered: This review focuses on surgical, respiratory and critical care settings discussing the most significant changes over the past decade with an increased focus on rehabilitation across the care continuum and a shift away from providing predominately airway clearance in established disease populations but also providing this in emerging groups. Further important changes are identification and emphases on patient self-management including changing their behaviour to more positively embrace wellness, particularly increasing physical activity levels. This paper outlines these changes and offers speculation on factors that may impact the profession in the future. Expert commentary: The increasing focus on new technologies, physical activity levels, changes to the health systems in different countries and an increasingly comorbid and ageing society will shape the next steps in the evolution of cardiorespiratory physiotherapy. Continued research is vital to keep pace with these changes so that physiotherapists can provide the most effective treatments to improve patient outcomes.

Barriers and facilitators to early rehabilitation in mechanically ventilated patients-a theory-driven interview study

Background

Despite a supportive evidence base and a push to implement, the uptake of early rehabilitation in critical care has been inconsistent. The objective of this study was to explore barriers and facilitators to early rehabilitation for critically ill patients receiving invasive mechanical ventilation.

Methods

Using the Theoretical Domains Framework (TDF) of behavior change, we conducted semi-structured interviews exploring barriers and facilitators to early rehabilitation among four purposively sampled ICU clinician groups (nurses, rehabilitation professionals, respiratory therapists, and physicians). The TDF is a comprehensive framework of 14 “construct domains,” synthesized from 33 theories of behavior that was developed to study determinants of behavior and to design interventions to improve evidence-based healthcare practice. A topic guide was developed and piloted based on the TDF and expert knowledge. Interviews were audio-recorded and transcribed verbatim. Transcripts were content analyzed by coding items into domains and then synthesized into more specific, over-arching themes or “beliefs.” An expert consensus group used structured decision rules to classify beliefs as high, moderate, or low in importance.

Results

We interviewed 40 stakeholders from the four clinician groups and identified 135 separate beliefs. Of these, 19 were classified as high, 40 as moderate, and 76 of low importance as barriers or facilitators. All beliefs classified as highly important fell within one of seven TDF domains: skills, social/professional role and identity, beliefs about capabilities, beliefs about consequences, environmental context/resources, social influences, and behavioral regulation. Beliefs of lower importance fell under the following seven domains: knowledge; optimism; reinforcement; intention; goals; memory, attention, and decision processes; and emotion. Quantitative differences in stated beliefs about early rehabilitation between professional groups were not common.

Conclusions

This study identified important barriers and facilitators to early rehabilitation in critical care patients. Domains identified as important should be considered when designing interventions to increase uptake of early rehabilitation.

The ICU Mobility Scale Has Construct and Predictive Validity and Is Responsive. A Multicenter Observational Study

RATIONALE

The ICU Mobility Scale (IMS) is a measure of mobility milestones in critically ill patients.

OBJECTIVES

This study aimed to determine the validity and responsiveness of the IMS from a prospective cohort study of adults admitted to the intensive care unit (ICU).

METHODS

Construct and predictive validity were assessed by comparing IMS values at ICU discharge in 192 patients to other variables using Spearman rank correlation coefficient, Mann-Whitney U tests, and logistic regression. Responsiveness was assessed using change over time, effect size, floor and ceiling effects, and percentage of patients showing change.

MEASUREMENTS AND MAIN RESULTS

The IMS at ICU discharge demonstrated a moderate correlation with muscle strength (r = 0.64, P < 0.001). There was a significant difference between the IMS at ICU discharge in patients with ICU-acquired weakness (median, 4.0; interquartile range, 3.0-5.0) compared with patients without (median, 8.0; interquartile range, 5.0-8.0; P < 0.001). Increasing IMS values at ICU discharge were associated with survival to 90 days (odds ratio [OR], 1.38; 95% confidence interval [CI], 1.14-1.66) and discharge home (OR, 1.16; 95% CI, 1.02-1.32) but not with return to work at 6 months (OR, 1.09; 95% CI, 0.92-1.28). The IMS was responsive with a significant change from study enrollment to ICU discharge (d = 0.8, P < 0.001), with IMS values increasing in 86% of survivors during ICU admission. No substantial floor (14% scored 0) or ceiling (4% scored 10) effects were present at ICU discharge.

CONCLUSIONS

Our findings support the validity and responsiveness of the IMS as a measure of mobility in the ICU.

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016)

Background and Purpose

The Japanese Clinical Practice Guidelines for Management of Sepsis and Septic Shock 2016 (J-SSCG 2016), a Japanese-specific set of clinical practice guidelines for sepsis and septic shock created jointly by the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine, was first released in February 2017 in Japanese. An English-language version of these guidelines was created based on the contents of the original Japanese-language version.

Methods

Members of the Japanese Society of Intensive Care Medicine and the Japanese Association for Acute Medicine were selected and organized into 19 committee members and 52 working group members. The guidelines were prepared in accordance with the Medical Information Network Distribution Service (Minds) creation procedures. The Academic Guidelines Promotion Team was organized to oversee and provide academic support to the respective activities allocated to each Guideline Creation Team. To improve quality assurance and workflow transparency, a mutual peer review system was established, and discussions within each team were open to the public. Public comments were collected once after the initial formulation of a clinical question (CQ), and twice during the review of the final draft. Recommendations were determined to have been adopted after obtaining support from a two-thirds (>66.6%) majority vote of each of the 19 committee members.

Results

A total of 87 CQs were selected among 19 clinical areas, including pediatric topics and several other important areas not covered in the first edition of the Japanese guidelines (J-SSCG 2012). The approval rate obtained through committee voting, in addition to ratings of the strengths of the recommendation and its supporting evidence were also added to each recommendation statement. We conducted meta-analyses for 29 CQs. Thirty seven CQs contained recommendations in the form of an expert consensus due to insufficient evidence. No recommendations were provided for 5 CQs.

Conclusions

Based on the evidence gathered, we were able to formulate Japanese-specific clinical practice guidelines that are tailored to the Japanese context in a highly transparent manner. These guidelines can easily be used not only by specialists, but also by non-specialists, general clinicians, nurses, pharmacists, clinical engineers, and other healthcare professionals.

Timing and Amount of Physical Therapy Treatment are Associated with Length of Stay in the Cardiothoracic ICU

Significant variability exists in physical therapy early mobilization practice. The frequency of physical therapy or early mobilization of patients in the cardiothoracic intensive care unit and its effect on length of stay has not been investigated. The goal of our research was to examine variables that influence physical therapy evaluation and treatment in the intensive care unit using a retrospective chart review. Patients (n = 2568) were categorized and compared based on the most common diagnoses or surgical procedures. Multivariate semi-logarithmic regression analyses were used to determine correlations. Differences among patient subgroups for all independent variables other than age and for length of stay were found. The regression model determined that time to first physical therapy evaluation, Charlson Comorbidity Index score, mean days of physical therapy treatment and mechanical ventilation were associated with increased hospital length of stay. Time to first physical therapy evaluation in the intensive care unit and the hospital, and mean days of physical therapy treatment associated with hospital length of stay. Further prospective study is required to determine whether shortening time to physical therapy evaluation and treatment in a cardiothoracic intensive care unit could influence length of stay.

Fifty Years of Research in ARDS. Long-Term Follow-up after Acute Respiratory Distress Syndrome. Insights for Managing Medical Complexity after Critical Illness

Critical illness is not a discrete disease state or syndrome. It is the culmination of a multiplicity of heterogeneous disease states and their varied health trajectories leading to extreme illness that requires advanced life support in a distinct geographic location in the hospital. It is a marker of newly acquired or worsened medical complexity and multimorbidities. Fifty years ago, distinguished critical care colleagues identified a syndrome of severe lung injury that united a group of patients with disparate admitting diagnoses. Acute respiratory distress syndrome continues to represent an important, incremental insult and risk modifier of acute and longer-term outcome, but it does not solely define our patients or their outcomes in isolation. Over the next 50 years, our research and clinical agenda needs to sharpen our lens on the fundamental importance of our patients' pre-critical illness health status, their intrinsic susceptibilities to tissue injury, and their innate and varied resiliencies. We need to take responsibility for the contribution that we make to morbidity through our practice in the intensive care unit each day. Engagement in frank and transparent communication with our patients and their caregivers about the very real and morbid consequences of being this sick is essential. We must enforce explicit consent about the morbidity of innovative, experimental, or high-risk medical and surgical procedures and ensure that our ongoing level of treatment aligns with patients' and caregivers' goals and values. Interprofessional and multidisciplinary collaboration is crucial to modify existing complex care pathways for our patients and their families to foster optimal rehabilitation and reintegration into the workplace and community.

Intensive Care Syndrome: Promoting Independence and Return to Employment (InS:PIRE). Early evaluation of a complex intervention

BACKGROUND

Many patients suffer significant physical, social and psychological problems in the months and years following critical care discharge. At present, there is minimal evidence of any effective interventions to support this patient group following hospital discharge. The aim of this project was to understand the impact of a complex intervention for ICU survivors.

METHODS

Quality improvement project conducted between September 2014 and June 2016, enrolling 49 selected patients from one ICU in Scotland. To evaluate the impact of this programme outcomes were compared to an existing cohort of patients from the same ICU from 2008-2009. Patients attended a five week peer supported rehabilitation programme. This multidisciplinary programme included pharmacy, physiotherapy, nursing, medical, and psychology input. The primary outcome in this evaluation was the EQ-5D, a validated measure of health-related quality of life. The minimally clinically important difference (MCID) in the EQ-5D is 0.08. We also measured change in self-efficacy over the programme duration. Based on previous research, this study utilised a 2.4 (6%) point change in self-efficacy scores as a MCID.

RESULTS

40 patients (82%) completed follow-up surveys at 12 months. After regression adjustment for those factors known to impact recovery from critical care, there was a 0.07-0.16 point improvement in quality of life for those patients who took part in the intervention compared to historical controls from the same institution, depending on specific regression strategy used. Self-efficacy scores increased by 2.5 points (6.25%) over the duration of the five week programme (p = 0.003), and was sustained at one year post intervention. In the year following ICU, 15 InS:PIRE patients returned to employment or volunteering roles (88%) compared with 11 (46%) in the historical control group (p = 0.15).

CONCLUSIONS AND RELEVANCE

This historical control study suggests that a complex intervention may improve quality of life and self-efficacy in survivors of ICU. A larger, multi-centre study is needed to investigate this intervention further.

The role of occupational and physiotherapy in multi-modal approach to tackling delirium in the intensive care

The presence of delirium within critical care remains a long-standing challenge for patients and clinicians alike. A myriad of pre-disposing and precipitating factors lead to this patient cohort being high risk for developing delirium during their critical care stay. Until now, non-pharmacological management of these patients usually encompasses a 'bundle' of principles to reduce delirium days. These bundles have limited focus on the entire multi-disciplinary team (including occupational therapists and physiotherapists) who could assist with the reduction of delirium. The purpose of this analysis is to review the current literature and develop a mnemonic, which may help facilitate collaborative working for patients with delirium. Electronic databases were searched for non-pharmacological managements of delirium within intensive care settings, after 2006. Critical appraisal using Critical Appraisal Skills Programme methodology was completed by the author. Multi-intervention approaches and bundles are successful at reducing delirium days, and in some cases, reducing hospital length of stay. The key components of these bundles include spontaneous breathing trials, daily sedation holds, addressing pain relief, early mobilisation and to a small extent normalisation of a daily routine. There is limited research into the role of therapy within this patient group, but there is a role for cognitive therapy, functional tasks, and a greater rehab emphasis within other patient populations such as stroke and elderly care. The critical care population have similar rehabilitation needs to these groups, and therefore would benefit from similar treatment plans. Critical care patients with delirium may benefit from a range of additional therapeutic activities to reduce the duration of delirium. The D.E.L.I.R.I.U.M mnemonic has been developed to encompass all the key elements of current delirium research in a simplistic memorable fashion. Further work is needed to trial the usefulness of the mnemonic in clinical practice to enable the entire multi-disciplinary team work collaboratively to reduce delirium with the intensive care.

Early Exercise in Critically Ill Youth and Children, a Preliminary Evaluation: The wEECYCLE Pilot Trial

OBJECTIVES

To determine the feasibility of conducting a full trial evaluating the efficacy of early mobilization using in-bed cycling as an adjunct to physiotherapy, on functional outcomes in critically ill children.

DESIGN

Single center, pilot, randomized controlled trial.

SETTING

Twelve-bed tertiary care, medical-surgical PICU at McMaster Children's Hospital, Hamilton, ON, Canada.

PATIENTS

Children 3-17 years old who were limited to bed-rest with an expected PICU stay of at least 48 hours. Patients were excluded if they were at their baseline level of function, already mobilizing out of bed or expected to do so within 24 hours.

INTERVENTIONS

Patients were randomized in a 2:1 ratio to early mobilization using in-bed cycling in addition to usual care physiotherapy (cycling arm) or to usual care physiotherapy alone (control). Usual care was according to institutional practice guidelines. The primary outcome was feasibility and safety.

MEASUREMENTS AND MAIN RESULTS

Thirty patients were enrolled (20 to the cycling and 10 to control) over a 12-month period, at a 93.7% consent rate. The median (interquartile range) time from PICU admission to mobilization was 1.5 days (1-3) in the cycling arm and 2.5 days (2-7) in the control arm. Total duration of mobilization therapy in PICU was 210 (152-380) and 136 minutes (42-314 min) in cycling and control arms, respectively. Total number of PICU days mobilized was 5.0 (3-6) with cycling and 2.5 (2-4.8) with usual care. No adverse events occurred in either arm. The main threat to feasibility of mobilization was the availability of physiotherapists or research personnel.

CONCLUSIONS

Early mobilization is safe and feasible in the PICU. In-bed cycling may facilitate greater duration and intensity of mobilization, in critically ill children. A full-scale randomized controlled trial is warranted to evaluate the efficacy of this intervention on PICU-acquired morbidities and functional outcomes in this population.
