ICU-based rehabilitation and its appropriate metrics

Towards a common definition of hospital-acquired deconditioning in adults: a scoping review

BACKGROUND

Hospital-acquired deconditioning is a term used in clinical practice, describing a loss of physical and/or cognitive function associated with hospitalisation. Previous reviews have addressed interventions, its prevalence in older adults and potential assessment tools. However, each review has reported a core limitation, the need for an agreed-upon definition and diagnostic criteria for hospital-acquired deconditioning.

OBJECTIVE

We aimed to identify key components used to define hospital-acquired deconditioning in adults. We sought to do this by identifying diagnostic criteria, describing how authors operationalised Hospital- Acquired Deconditioning (HAD), and describing differences between HAD and other immobility-linked syndromes. This article focuses on how hospital-acquired deconditioning is understood and operationalised.

DESIGN

A scoping review using the Joanna Briggs Institute methodology for evidence synthesis.

ELIGIBILITY CRITERIA

Published in English after 1 January 1990, investigating adults over 18, set in inpatient rehabilitation or acute care settings, and including either a definition or description of hospital-acquired deconditioning or an outline of strategies to assess, prevent or manage hospital-acquired deconditioning.

SOURCES OF EVIDENCE

Published and grey literature, no restriction was placed on study design.

CHARTING METHODS

Relevant data, where available, was extracted from each source using a proprietary data extraction template.

RESULTS

One hundred and three articles were included from 2403 retrieved results. Thirty-three were from rehabilitation or post-acute care settings, 53 from acute care, 15 from intensive care and two from other settings. The literature was diverse in methodology and research question addressed. Hospital-acquired deconditioning was poorly defined, no consistent patterns were identified in aetiology and sequelae; diagnostic criteria were not fully agreed on.

CONCLUSIONS

The literature on hospital-acquired deconditioning is large, diverse and incomplete. Further work is required to develop a shared definition of hospital-acquired deconditioning, enabling researchers to coalesce for better understanding of the phenomenon, and clinicians, in turn, to better treat and mitigate against it.

Patient perceptions of ICU physiotherapy: 'Your body needs to go somewhere to be recharged … '

Background

Patient satisfaction is an essential concept to consider for the improvement of quality care in healthcare centres and hospitals and has been linked to increased patient compliance with treatment plans, better patient safety and improved clinical outcomes.

Objectives

As part of a before-and-after clinical trial aimed to investigate the implementation of an evidence-based and -validated physiotherapy protocol within a surgical intensive care unit (ICU), we decided to include the patient perception of physiotherapy received in the intervention unit.

Methods

A nested, exploratory, descriptive, qualitative study design was adopted. Purposively selected adult patients discharged from ICU during the implementation phase of the trial were interviewed.

Results

Eighteen patients (10 male) with a median age of 44 years and median ICU length of stay (LOS) of six days were included. Three themes and nine categories emerged: (i) linking therapy to clinical outcome (patient expectations and understanding; physiotherapy activities and the implication of mobilisation; physiotherapy benefits and progression); (ii) the importance of developing a trusting relationship (physiotherapy value; safety; continuity of care); and (iii) communication (satisfaction; interactions and patient perception and experience of physiotherapy).

Conclusion

While confirming barriers to early mobility, patients perceived participation in mobility activities as a marked jolt in their journey to recovery following a critical incident. Effective communication and preservation of trust between physiotherapist and patient are essential for understanding expectations and can facilitate improved outcomes. Clinicians can use the information when managing critically ill patients. Including patient-reported outcomes to measure physiotherapy interventions used in the ICU is feasible and can inform the development of such outcomes.

Contribution of the study

The study highlights the feasibility and importance of the use of patient-reported outcomes to measure physiotherapy interventions and informs the development of patient reported outcomes and the importance of patient centred physiotherapy care in the ICU setting.

Occupational therapy service provision in adult intensive care units in Australia: A survey of workload practices, interventions and barriers

INTRODUCTION

Occupational therapy practice within intensive care units (ICUs) is limited with respect to published research evidence and guidelines regarding scope of practice. An understanding of the current level of service provision, feasibility of services in ICUs and training and development needs of occupational therapists is required to enable consistent best practice and promote the occupational therapy profile. This study aimed to explore occupational therapy practice within ICUs in Australia including the barriers and enablers to practice perceived by occupational therapists.

METHODS

In this cross-sectional study, a national customised online survey was completed by registered occupational therapists who provide services in intensive care settings in Australia. Recruitment was from July to September 2019 through Occupational Therapy Australia and other professional networks and interest groups.

RESULTS

The survey was completed by 43 respondents. The majority were experienced therapists from Queensland with greater than 10-years post-qualification and working in a tertiary hospital setting. The most common length of time spent working in the ICU was 0-2 h per week. Formal and informal self-care measures, cognitive screens and physical outcome measures were commonly used. Bed-based grooming retraining, pressure care management, functional upper limb retraining and passive ranging were the most frequent interventions provided on a daily basis. Perceived barriers to occupational therapy service provision in ICU included lack of funding for staffing, competing workload demands, lack of occupational therapy role delineation and scope of practice and lack of published evidence and training.

CONCLUSION

Occupational therapy services in intensive care settings in Australia are limited. Published practice guidelines, further research, applications for service funding and ongoing education of the ICU multidisciplinary team regarding the scope of occupational therapy practice are recommended to promote the development of occupational therapy services in ICU.

Building a culture of early mobilization in the pediatric intensive care unit-a nuts and bolts approach

The culture of sedation and immobilization in the pediatric intensive care unit (PICU) is associated with PICU-acquired weakness, delirium, and poor functional, neurocognitive and psychosocial outcomes. A structured approach to introducing physical activity, as early as possible after PICU admission, may prevent these complications and optimize the holistic outcomes of critically ill children. Changing culture and introducing new clinical practice in PICU is complex, but can be approached systematically, using a "nuts and bolts" approach targeting the basic, practical considerations and essential required elements or components. Extending the construction analogy, this article reviews the relevant literature to describe the essential elements required to build and sustain a successful and safe early mobility program in the PICU. Effective early mobilization requires individual patient assessment and goal setting, using a collaborative inter-disciplinary, patient- and family-centered approach, to ensure mobility goals and physical activities are appropriate for the patient's age, condition/s, premorbid function, strength, endurance and developmental level. Early mobility activities for the pediatric age spectrum include active or active-assisted range of motion exercises, neurodevelopmental play, use of mobility devices, in-bed exercises, transfers, sitting or standing tolerance, crawling, pre-gait activities, ambulation and activities of daily living, with a focus on play as function. Although there are few complete contraindications to early mobilization, appropriate precautions and preparation should be taken to mitigate potential safety concerns. Although there are many perceived barriers to early mobilization in the PICU, at the level of patient, provider, institution and knowledge translation; these are not objectively associated with increased risk during mobilization and can be overcome through an engaged process of practice change by all members of the interprofessional clinical team. Early mobility programs could be initiated in PICU as systematic quality improvement initiatives, with established processes to optimize structural, process and system elements and to provide continual feedback, measurement, benchmarking and collaboration; to ultimately impact on measurable patient outcomes. Early, graded, and individually prescribed mobilization should be considered as part of the standard PICU "package of care" for all critically ill and injured children, in order to improve their functional status and quality of life after PICU discharge.

Early mobilization in clinical practice: the reliability and feasibility of the 'Start To Move' Protocol

PURPOSE

The properties of a local Intensive Care Unit early mobilization protocol ('Start To Move As Soon As Possible') in critically ill patients, consisting of an objective diagnostic assessment linked to six treatment levels were evaluated. This study aimed to investigate whether the protocol can be reliably applied by different health-care providers (reliability), to examine the associations between prescribed and delivered treatments (feasibility) and to explore safety and patient satisfaction with the protocol.

METHODS

Cross-sectional observational study evaluating the reliability of the protocol between physiotherapist was evaluated with Cohen's kappa, percentage of agreement, and intraclass correlation coefficients in 61 patients. Feasibility was analyzed as agreement between prescribed and delivered treatments with Spearman's rank correlation coefficients in 60 patients. A satisfaction survey was used to evaluate patient satisfaction with the protocol.

RESULTS

Excellent agreement was observed between physiotherapists for diagnostic level assignment (Kappa = 0.92), while the majority of the treatment proposals per level showed moderate to substantial agreement between the physiotherapists (Kappa range: 0.40-0.89). Three hundred and thirteen treatments were prescribed. Perfect agreement was observed between prescribed and delivered treatments in level 0 (Spearman's rho 1.00) and excellent associations for levels 1-5 (0.941, 0.995, 0.951, 0.998, and 0.999), respectively. Unwanted safety events rate was 3%. Most patients (92%) were very satisfied with physiotherapy.

CONCLUSION

Excellent inter-rater agreement for diagnostic level assignment and moderate to substantial agreement for proposed treatments support the reliability of the protocol. Perfect to excellent associations between prescribed and delivered treatments supports its feasibility. Complications were rare, and most patients were very positive regarding the care provided by physiotherapists during their stay in the ICU.

Early Therapeutic Mobility and Changes in Scores for Pain and Fatigue

This report is a secondary analysis of data from a larger study of a nurse-led early therapeutic mobility intervention among patients receiving mechanical ventilation. This analysis evaluated whether intervention frequency or intensity was associated with pain or fatigue. Frequency was defined as once-daily versus twice-daily interventions. Intensity was defined as low (in-bed activities) or moderate (out-of-bed activities). Thirty-nine patients self-reported pain and fatigue immediately before and after the intervention. Neither pain nor fatigue increased significantly (mean increase, <1 [scale of 0-10] for 95% of interventions). Four patients reported decrements in pain; 1 reported a decrease in fatigue. Less than 5% of enrolled patients indicated a score change of +4 to +6 for pain or fatigue, typically with the first intervention that included sitting at the edge of the bed. Future research could examine the distress associated with these symptoms in critically ill adults receiving early therapeutic mobility interventions.

Intensive Care Physiotherapy during Extracorporeal Membrane Oxygenation for Acute Respiratory Distress Syndrome

RATIONALE

There are limited data on physiotherapy during extracorporeal membrane oxygenation (ECMO) for acute respiratory distress syndrome (ARDS).

OBJECTIVES

We sought to characterize physiotherapy delivered to patients with ARDS supported with ECMO, as well as to evaluate the association of this therapeutic modality with mortality.

METHODS

We conducted a retrospective cohort study of all adult patients with ARDS supported with ECMO at our institution between 2010 and 2015. The highest level of daily activity while on ECMO was coded using the ICU Mobility Scale. Through multivariable logistic regression, we evaluated the association between intensive care unit (ICU) physiotherapy and ICU mortality. In an exploratory univariate analysis, we also evaluated factors associated with a higher intensity of ICU rehabilitation while on ECMO.

MEASUREMENTS AND MAIN RESULTS

Of 107 patients who underwent ECMO, 61 (57%) had ARDS requiring venovenous ECMO. The ICU physiotherapy team was consulted for 82% (n = 50) of patients. Thirty-nine percent (n = 18) of these patients achieved an activity level of 2 or higher (active exercises in bed), and 17% (n = 8) achieved an activity level 4 or higher (actively sitting over the side of the bed). In an exploratory analysis, consultation with the ICU physiotherapy team was associated with decreased ICU mortality (odds ratio, 0.19; 95% confidence interval, 0.04-0.98). In univariate analysis, severity-of-illness factors differentiated higher-intensity and lower-intensity physiotherapy.

CONCLUSIONS

Physiotherapy during ECMO is feasible and safe when performed by an experienced team and executed in stages. Although our study suggests an association with improved ICU mortality, future research is needed to identify potential barriers, optimal timing, dosage, and safety profile.

Pain, agitation, and delirium guidelines: nurses' involvement in development and implementation

The 2013 American College of Critical Care Medicine/Society of Critical Care Medicine clinical practice guidelines for the management of pain, agitation, and delirium in adult patients in the intensive care unit serves as a living example of nurses' involvement in the development and implementation of professional guidelines. Nurses who served on this guideline-writing panel describe their experiences. Specific examples from the pain, agitation, and delirium guidelines for care are used to explore the roles of the nurse leader, nurse informaticist, staff nurse, and nurse researcher in relationship to guideline implementation.

Early Mobilization of Mechanically Ventilated Patients

Critically ill patients requiring mechanical ventilation are least likely to be mobilized and, as a result, are at-risk for prolonged complications from weakness. The use of bed rest and sedation when caring for mechanically ventilated patients is likely shaped by historical practice; however, this review demonstrates early mobilization, with little to no sedation, is possible and safe. Assessing readiness for mobilization in context of progressing patients from passive to active activities can lead to long-term benefits and has been achievable with resource-efficient implementations and team work.

A new two-tier strength assessment approach to the diagnosis of weakness in intensive care: an observational study

INTRODUCTION

Intensive care unit-acquired weakness (ICU-AW) is a significant problem. There is currently widespread variability in the methods used for manual muscle testing and handgrip dynamometry (HGD) to diagnose ICU-AW. This study was conducted in two parts. The aims of this study were: to determine the inter-rater reliability and agreement of manual muscle strength testing using both isometric and through-range techniques using the Medical Research Council sum score and a new four-point scale, and to examine the validity of HGD and determine a cutoff score for the diagnosis of ICU-AW for the new four-point scale.

METHODS

Part one involved evaluation of muscle strength by two physical therapists in 29 patients ventilated >48 hours. Manual strength testing was performed by both physical therapists using two techniques: isometric and through range; and two scoring systems: traditional six-point Medical Research Council scale and a new collapsed four-point scale. Part two involved assessment of handgrip strength conducted on 60 patients. A cutoff score for ICU-AW was identified for the new four-point scoring system.

RESULTS

The incidence of ICU-AW was 42% (n = 25/60) in this study (based on HGD). In part one the highest reliability and agreement was observed for the isometric technique using the four-point scale (intraclass correlation coefficient = 0.90: kappa = 0.72 respectively). Differences existed between isometric and through-range scores (mean difference = 1.76 points, P = 0.005). In part two, HGD had a sensitivity of 0.88 and specificity of 0.80 for diagnosing ICU-AW. A cutoff score of 24 out of 36 points was identified for the four-point scale.

CONCLUSIONS

The isometric technique is recommended with reporting on a collapsed four-point scale. Because HGD is easy to perform and sensitive, we recommend a new two-tier approach to diagnosing ICU-AW that first tests handgrip strength with follow-up strength assessment using the isometric technique for muscle strength testing if handgrip strength falls below cutoff scores. Whilst our results for the four-point scale are encouraging, further research is required to confirm the findings of this study and determine the validity of the four-point scoring system and cutoff score developed of less than 24 out of 36 before recommending adoption into clinical practice.

Electrical muscle stimulation in the intensive care setting: a systematic review

CONTEXT

The role of electrical muscle stimulation in intensive care has not previously been systematically reviewed.

OBJECTIVES

To identify, evaluate, and synthesize the evidence examining the effectiveness and the safety of electrical muscle stimulation in the intensive care, and the optimal intervention variables.

DATA SOURCES

A systematic review of articles using eight electronic databases (Cumulative Index to Nursing and Allied Health Literature, Cochrane Library, Excerpta Medica Database, Expanded Academic ASAP, MEDLINE, Physiotherapy Evidence Database, PubMed, and Scopus) personal files were searched, and cross-referencing was undertaken.

ELIGIBILITY CRITERIA

Quantitative studies published in English, assessing electrical muscle stimulation in intensive care, were included.

DATA EXTRACTION AND DATA SYNTHESIS

One reviewer extracted data using a standardized form, which were cross-checked by a second reviewer. Quality appraisal was undertaken by two independent reviewers using the Physiotherapy Evidence Database and Newcastle-Ottawa scales, and the National Health and Medical Research Council Hierarchy of Evidence Scale. Preferred Reporting Items for Systematic Reviews guidelines were followed.

RESULTS

Nine studies on six individual patient groups of 136 participants were included. Eight were randomized controlled trials, with four studies reporting on the same cohort of participants. Electrical muscle stimulation appears to preserve muscle mass and strength in long-stay participants and in those with less acuity. No such benefits were observed when commenced prior to 7 days or in patients with high acuity. One adverse event was reported. Optimal training variables and safety of the intervention require further investigation.

CONCLUSIONS

Electrical muscle stimulation is a promising intervention; however, there is conflicting evidence for its effectiveness when administered acutely. Outcomes measured are heterogeneous with small sample sizes.
