Early Mobility in the Intensive Care Unit: Evidence, Barriers, and Future Directions

Critical care beyond organ support: the importance of geriatric rehabilitation

Very old critically ill patients pose a growing challenge for intensive care. Critical illness and the burden of treatment in the intensive care unit (ICU) can lead to a long-lasting decline of functional and cognitive abilities, especially in very old patients. Multi-complexity and increased vulnerability to stress in these patients may lead to new and worsening disabilities, requiring careful assessment, prevention and rehabilitation. The potential for rehabilitation, which is crucial for optimal functional outcomes, requires a systematic, multi-disciplinary approach and careful long-term planning during and following ICU care. We describe this process and provide recommendations and checklists for comprehensive and timely assessments in the context of transitioning patients from ICU to post-ICU and acute hospital care, and review the barriers to the provision of good functional outcomes.

Early rehabilitation after spinal cord injury: a scoping review protocol

OBJECTIVE

The objective of this scoping review is to identify the timings and types of early rehabilitation after spinal cord injuries (SCI) that are documented in the literature, as well as identify possible research gaps in this field.

INTRODUCTION

Preclinical and clinical studies support the idea that early rehabilitation may be beneficial for patients with acute SCI. However, the timing and types of rehabilitation that should and could be used in the acute stage are still unclear. The first step towards such knowledge is to extensively review what is documented in the literature.

INCLUSION CRITERIA

This review will consider all papers focusing on early rehabilitation after SCI in adult humans or animals (<3 months post-SCI for humans and other primates and <3 weeks post-SCI for other animals). Interventions in the included papers must aim at sensorimotor or functional improvement and take place in a hospital or a rehabilitation center if they target human subjects.

METHODS

MEDLINE (PubMed), Scopus, Embase (Embase.com), PEDro, Web of Science Core Collection, CINAHL (EBSCOhost), Cochrane Database of Systematic Reviews, Cochrane CENTRAL, PROSPERO, ClinicalTrials.gov, and gray literature sources will be searched for eligible articles.

Improving Outcomes in Mechanically Ventilated Adult ICU Patients Following Implementation of the ICU Liberation (ABCDEF) Bundle Across a Large Healthcare System

OBJECTIVES

To measure how the ICU Liberation Bundle (aka ABCDEF Bundle or the Bundle) affected clinical outcomes in mechanically ventilated (MV) adult ICU patients, as well as bundle sustainability and spread across a healthcare system.

DESIGN

We conducted a multicenter, prospective, cohort observational study to measure bundle performance versus patient outcomes and sustainability in 11 adult ICUs at six community hospitals. We then prospectively measured bundle spread and performance across the other 28 hospitals of the healthcare system.

SETTING

A large community-based healthcare system.

PATIENTS

In 11 study ICUs, we enrolled 1,914 MV patients (baseline n = 925, bundle performance/outcomes n = 989), 3,019 non-MV patients (baseline n = 1,323, bundle performance/outcomes n = 1,696), and 2,332 MV patients (bundle sustainability). We enrolled 9,717 MV ICU patients in the other 28 hospitals to assess bundle spread.

INTERVENTIONS

We used evidence-based strategies to implement the bundle in all 34 hospitals.

MEASUREMENTS AND MAIN RESULTS

We compared outcomes for the 12-month baseline and bundle performance periods. Bundle implementation reduced ICU length of stay (LOS) by 0.5 days (p = 0.02), MV duration by 0.6 days (p = 0.01), and ICU LOS greater than or equal to 7 days by 18.1% (p < 0.01). Performance period bundle compliance was compared with the preceding 3-month baseline compliance period. Compliance with pain management and spontaneous awakening trial (SAT) and spontaneous breathing trial (SBT) remained high, and reintubation rates remained low. Sedation assessments increased (p < 0.01) and benzodiazepine sedation use decreased (p < 0.01). Delirium assessments increased (p = 0.02) and delirium prevalence decreased (p = 0.02). Patient mobilization and ICU family engagement did not significantly improve. Bundle element sustainability varied. SAT/SBT compliance dropped by nearly half, benzodiazepine use remained low, sedation and delirium monitoring and management remained high, and patient mobility and family engagement remained low. Bundle compliance in ICUs across the healthcare system exceeded that of study ICUs.

CONCLUSIONS

The ICU Liberation Bundle improves outcomes in MV adult ICU patients. Evidence-based implementation strategies improve bundle performance, spread, and sustainability across large healthcare systems.

Effects of mobility dose on discharge disposition in critically ill stroke patients

BACKGROUND

Mobilization in the intensive care unit (ICU) has the potential to improve patient outcomes following acute stroke. The optimal duration and intensity of mobilization for patients with hemorrhagic or ischemic stroke in the ICU remain unclear.

OBJECTIVE

To assess the effect of mobilization dose in the ICU on adverse discharge disposition in patients after stroke.

DESIGN

This is an international, prospective, observational cohort study of critically ill stroke patients (November 2017-September 2019). Duration and intensity of mobilization was quantified daily by the mobilization quantification score (MQS).

SETTING

Patients requiring ICU-level care were enrolled within 48 hours of admission at four separate academic medical centers (two in Europe, two in the United States).

PARTICIPANTS

Participants included individuals (>18 years old) admitted to an ICU within 48 hours of ischemic or hemorrhagic stroke onset who were functionally independent at baseline.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURE

The primary outcome was adverse discharge disposition.

RESULTS

Of the patients screened, 163 were eligible for inclusion in the study. One patient was subsequently excluded due to insufficient data collection (n = 162). The dose of mobilization varied greatly between centers and patients, which could not be explained by patients' comorbidities or disease severity. High dose of mobilization (mean MQS > 7.3) was associated with a lower likelihood of adverse discharge (adjusted odds ratio, [aOR]: 0.14; 95% confidence interval [CI]: 0.06-0.31; p < .01).

CONCLUSION

The increased use of mobilization acutely in the ICU setting may improve patient outcomes.

Monitoring Active Patient Participation During Robotic Rehabilitation: Comparison Between a Robot-Based Metric and an EMG-Based Metric

While rehabilitation robots present a much-needed solution to improving early mobilization therapy in demanding clinical settings, they also present new challenges and opportunities in patient monitoring. Aside from the fundamental challenge of quantifying a patient's voluntary contribution during robot-led therapy motion, many sensors cannot be used in clinical settings due to time and space limitations. In this paper, we present and compare two metrics for monitoring a patient's active participation in the motion. The two metrics, each derived from first principles, have the same biomechanical interpretability, i.e., active work by the patient during the robotic mobilization therapy, but are calculated in two different spaces (Cartesian vs. muscle space). Furthermore, the sensors used to quantify these two metrics are fully independent from each other and the associated measurements are unrelated. Specifically, the robot-based work metric utilizes robot-integrated force sensors, while the EMG-based work metric requires electrophysiological sensors. We then apply the two metrics to therapy performed using a clinically certified, commercially available robotic system and compare them against the specific instructions given to the healthy subjects as well as against each other. Both metric outputs qualitatively match the expected behavior of the healthy subjects. Additionally, strong correlations (median [Formula: see text]) are shown between the two metrics, not only for healthy subjects (n = 12) but also for patients (n = 2), providing solid evidence for their validity and translatability. Importantly, the robot-based work metric does not rely on any sensors outside of those integrated into the robot, thus making it ideal for application in clinical settings.

Knowledge, attitude and practice regarding hypoactive delirium among ICU nurses: A nationwide cross-sectional study

AIMS AND OBJECTIVES

This study aimed to assess the knowledge, attitude and practice (KAP) of intensive care unit (ICU) nurses in patients with hypoactive delirium in China.

BACKGROUND

The presentation of hypoactive delirium is not obvious and tends to be ignored. However, it has a high incidence and can cause critical impairment. Although nurses are the primary caregivers of patients, the evidence of the current status of KAP of hypoactive delirium among ICU nurses is insufficient in China.

DESIGN

The study participants were 2835 ICU nurses from 201 hospitals in 69 cities from 31 provinces in China.

METHODS

The current status of KAP of hypoactive delirium among ICU nurses was determined using a self-reported structured questionnaire, including 52 questions covering general personal information; three dimensions of KAP; and relevant issues. Descriptive analyses of the sample distribution were reported as percentages and medians. The factors were detected using univariate and multivariate analyses. To guide the reporting of the research, a STROBE checklist of cross-sectional studies was used.

RESULTS

Of the 3101 returned questionnaires, 2835 were analyzed. Approximately 64. 94 % and 53. 30 % of them were identified with a positive attitude and appropriate practice, respectively, whereas only 1. 48 % showed a good level of knowledge. The regression analysis showed that age, years of working in the ICU, educational background, professional title, caring for patients with delirium, attending training on hypoactive delirium and hospital grading were significantly associated with their KAP status(P＜005).

CONCLUSIONS

Hypoactive delirium is an ignored entity by nursing professionals, with no definite nursing procedure. This study shows that receiving relevant training is a factor affecting KAP status, indicating that training should be strengthened. Additionally, appropriate screening and nursing procedures should be developed to standardize the behavior of ICU nurses and improve the quality of care.

RELEVANCE TO CLINICAL PRACTICE

ICU nurses have poor knowledge of hypoactive delirium and related training should be strengthened, especially for middle-aged nurses. Screening and nursing procedures should be set up, which is critical to promote nursing practice.

Relationship Between Delirium Development and Its Causative Factors in the Intensive Care Unit After Cardiac Surgery

Background

Delirium is a clinical symptom that can have serious side effects in patients, and it develops acutely and shows reversibility. Postoperative delirium is an important neuropsychological complication after surgery that directly or indirectly affects patients.

Cardiac surgery increases the risk of delirium due to the complexity of surgical procedures, use of intraoperative and postoperative anesthetics and other pharmacologic agents, and possible postoperative complications. This study aims to determine the relationship between the development of delirium and its causative factors after cardiac surgery and its associated postoperative complications, and identify the high-relevance risk factors of postoperative delirium.

Methods

The participants comprised 730 patients who were admitted to the intensive care unit and underwent cardiac surgery. The collected data included 19 risk factors based on the patients' medical information records. As a delirium diagnostic tool, we used the Intensive Care Delirium Screening Checklist, with four or more points indicating delirium. For statistical analysis, the dependent variables were determined based on the presence or absence of delirium, while the independent variables were determined based on the risk factors of delirium. A t-test, χ² test, and logistic regression analysis were performed on risk factors between the two groups-the delirium group and no delirium group.

Results

Postoperative delirium was observed in 126 (17.3%) of 730 patients after cardiac surgery. Postoperative complications were more common in the delirium group. Independent risk factors associated with postoperative delirium were identified in 7 of the 12 factors.

Conclusion

As cardiac surgery is invasive and affects the development and severity of delirium, efforts and intervention methods are necessary to predict the risk factors for the development of delirium before surgery, and to prevent its occurrence after surgery. In the future, it is necessary to further investigate factors associated with delirium that can be directly intervened.

Early and progressive mobility in a community hospital: A new interdisciplinary safe patient handling and mobility model

Two-stage prediction model for postoperative delirium in patients in the intensive care unit after cardiac surgery

OBJECTIVES

Postoperative delirium is a common severe complication in patients in the intensive care unit after cardiac surgery. We developed a two-stage prediction model and quantified the risk of developing postoperative delirium to assist in early prevention before and after surgery.

METHODS

We conducted a prospective cohort study and consecutively recruited adult patients after cardiac surgery. The Confusion Assessment Method for patients in the intensive care unit was used to diagnose delirium 5 days postoperatively. The stage I model was constructed using patient demographics, health conditions and laboratory results obtained preoperatively, whereas the stage II model was built on both pre- and postoperative predictors. The model was validated internally using the bootstrap method and externally using data from an external cohort.

RESULTS

The two-stage model was developed with 654 patients and was externally validated with 214 patients undergoing cardiac surgery. The stage I model contained 6 predictors, whereas the stage II model included 10 predictors. The stage I model had an area under the receiver operating characteristic curve of 0.76 (95% confidence interval: 0.68-0.81), and the stage II model's area under the receiver operating characteristic curve increased to 0.85 [95% confidence interval (CI): 0.81-0.89]. The external validation resulted in an area under the curve of 0.76 (95% CI: 0.67-0.86) for the stage I model and 0.78 (95% CI: 0.69-0.86) for the stage II model.

CONCLUSIONS

The two-stage model assisted medical staff in identifying patients at high risk for postoperative delirium before and 24 h after cardiac surgery. This model showed good discriminative power and predictive accuracy and can be easily accessed in clinical settings.

TRIAL REGISTRATION

The study was registered with the US National Institutes of Health ClinicalTrials.gov (NCT03704324; registered 11 October 2018).

Multiple field tests on landing day: Early mobility may improve postural recovery following spaceflight

Adaptation to microgravity causes astronauts to experience sensorimotor disturbances during return to Earth leading to functional difficulties. Recently, the Field Test (FT) study involving an incrementally demanding sensorimotor functional test battery has allowed for an unprecedented view into early decrements and recovery from multiple tests conducted on the landing day following 6-months International Space Station missions. Although the protocol was challenging and temporarily increased motion sickness symptoms, there were anecdotal reports that performing these tasks within the first few hours of landing accelerated their recovery. Therefore, results from computerized dynamic posturography (CDP) following return to Houston were used to compare recovery between crewmembers that participated in FT (n = 18) with those that did not (controls, n = 11). While there were significant decrements in postural performance for both groups, some FT participants tended to perform closer to their preflight baseline in the most challenging condition of the CDP sensitive to vestibular function—eyes closed, unstable support and head movements. However, the distribution of difference scores appeared bimodal with other FT participants in the lower range of performance. We attribute these observations to the manner in which the field tests were implemented—some benefitted by encouraging early movement to drive adaptation when performed in a constrained incremental fashion; however, movements above aversive thresholds may have impaired adaptation in others. Challenging the sensorimotor system with increasingly provocative movements performed as close to landing as possible, as long as within individual thresholds, could be a useful intervention to accelerate astronaut’s sensorimotor readaptation that deserves further study.

Effects of an Electronic Health Record Tool on Team Communication and Patient Mobility: A 2-Year Follow-up Study

BACKGROUND

Intensive care unit early mobility programs improve patients' functional status and outcomes. An electronic health record-based communication tool improved interprofessional communication within an early mobility program. Long-term sustainability of this communication tool has not been evaluated.

LOCAL PROBLEM

Ineffective interprofessional communication was perceived as a barrier to success of an intensive care unit early mobility program at the project institution. An electronic health record-based communication tool was successfully implemented to improve communication. Sustaining the intervention is of continued importance.

METHODS

Longitudinal data were collected 2 years after initial implementation of the communication tool to evaluate its continued impact on patient outcomes and staff engagement with an intensive care unit early mobility program.

RESULTS

Initial implementation of the electronic health record-based communication tool resulted in statistically and clinically significant improvements in patient and staff metrics. Compared with postimplementation data, 2-year longitudinal follow-up data revealed nonsignificant changes in patient outcomes (time from admission to mobility goal, mechanical ventilation duration, length of intensive care unit stay, and discharge disposition recommendations to higher independence levels). Staff reported continued use of the communication tool and positive perceptions of its impact on the intensive care unit early mobility program.

CONCLUSIONS

Nonsignificant changes in patient outcomes may indicate sustainment of the effect of the communication tool's original implementation. Employing appropriate sustainment techniques is essential to maintain practice change. The electronic health record-based communication tool can improve interprofessional communication within an intensive care unit early mobility program, improving patient outcomes and staff teamwork.

Validity and Usefulness of an Electronic Health Care Record-Generated Mobility Ambulation Tool: The Human Body Was Designed to Move

BACKGROUND

Mobility is a vital function of human life. Nurses have an essential role in preventing hospitalized patient complications through movement and ambulation.

PURPOSE

This study examined the integration, accuracy, and precision of a paper-based mobility/ambulation tool into an electronic health record (EHR) to assess inpatient mobility/ambulation status.

METHODS

This multisite mixed-methods study was a time-series correlational evaluation of a mobility/ambulation tool into the EHR.

RESULTS

Sustainability data revealed strong correlations between nurse responses and EHR levels (r = 0.602; scores r = 0.624). Cronbach's α values were 0.737 and 0.761. Nurses' anecdotes supported the findings.

CONCLUSION

Findings revealed that the EHR-Mobility Ambulation Tool is a valid, reliable, and stable tool. EHR-generated scores can assist in reducing charting burden, care planning, and inform the interdisciplinary health team at all patient care stages. Tool adoption could potentially assist nurses plan interventions suitable to maintain or increase hospitalized patients' mobility status and contribute to discharge planning.

Effectiveness of Different Physiotherapy Protocols in Children in the Intensive Care Unit: A Randomized Clinical Trial

PURPOSE

This study aimed to investigate the effectiveness of different physical therapy protocols on the autonomic modulation of heart rate, time of invasive mechanical ventilation (IMV), and length of hospital stay.

METHODS

This was a randomized clinical study with 20 children on IMV in an intensive care unit (ICU), between July 2018 and September 2019. The control group (n = 10) performed the hospital's physical therapy protocol and the experimental group (n = 10) performed the physical therapy protocol based on physical exercise.

RESULTS

Higher values of heart rate variability were found in the experimental group, both in individual and intergroup analyses. There was a significant reduction in the time of IMV and ICU stay.

CONCLUSION

There was an improvement in heart rate variability, reduced time on mechanical ventilation and length of stay in the ICU in individuals who performed the study protocol.

Relationship between potential barriers to early mobilization in adult patients during intensive care stay using the Perme ICU Mobility score

Background

Identifying barriers to early mobilization is essential for the management of patients in the intensive care unit (ICU). Our objective was to identify the potential barriers to early mobilization in adult patients using the Perme ICU Mobility Score (Perme Score) and its relationship with days of mechanical ventilation (MV) and length of stay in ICU.

Methods

This was a pilot, observational, and prospective study. We included 142 adult patients admitted to a 14-bed ICU, in a fourth-level complexity hospital in Cali, Colombia. The Perme Score was used to evaluate potential barriers to mobility. We used the Spearman’s correlation coefficient to find potential correlations between the number of barriers to mobility per patient and the duration of MV and ICU stay.

Results

We identified significant inverse correlations between total days in MV and the total score of barriers to mobility at ICU admission (r = –0.773; p < 0.05) and at ICU discharge (r = –0.559; p < 0.05). Also, between ICU length of stay and total score of barriers to mobility at ICU admission (r = –0.420; p < 0.05) and at ICU discharge (r = –0.283; p < 0.05). Moreover, we found a significant correlation between total score of the barriers item and total Perme score (r = 0.91; p < 0.01).

Conclusions

Using the Perme Score we identified potential barriers to mobility upon admission to the ICU that were maintained until discharge. Our findings indicate a strong positive correlation at ICU admission between the total Perme Score and the total score of “Category #2 – Potential Mobility Barriers” in the Perme Score.

Lessons Learned From Implementing Rehabilitation at a COVID-19 Field Hospital

ABSTRACT

Rehabilitation experts play an important role in preventing hospital-acquired debility, increasing patients' abilities to safely perform activities of daily living, and facilitating discharge to the home setting for patients with COVID-19. Surges in COVID-19 hospitalization rates combined with increases in length of hospital stay and decreases in postacute care placements have necessitated the opening of COVID-19 field hospitals around the country. Most field hospitals lack the resources to offer a full suite of rehabilitation services, but there are opportunities for small teams of rehabilitation experts to increase their reach by using innovative strategies. This article describes the implementation of a small team of rehabilitation experts in a COVID-19 field hospital and strategies used by this team to maximize patient activity and mobility, facilitate timely discharge, and maximize the number of patients discharged to the home setting. Strategies include training nonclinical staff to assist with activity and mobility promotion and using a rehabilitation triage system to determine needs of individual patients and facilitate efficient resource utilization. The authors reflect on successful aspects of these strategies, as well as barriers to rehabilitation implementation, and make recommendations for other field hospitals seeking to implement rehabilitation during the COVID-19 pandemic or future health crises.

Nurses' Perceptions of Barriers to Out-of-Bed Activities Among Patients Receiving Mechanical Ventilation

BACKGROUND

Delays in early patient mobility are common in critical care areas. Oral intubation with mechanical ventilation is negatively associated with out-of-bed activities.

OBJECTIVES

To explore nurses' mobility practices for patients with oral intubation and mechanical ventilation and identify barriers related to patient, nurse, and environment-of-care factors specific to this population.

METHODS

In this cross-sectional, descriptive study in a medical intensive care unit, mobility was defined as standing, sitting in a chair, or walking. A total of 105 patients who met predefined mobility criteria and their 48 nurses were enrolled. Nurses were interviewed about mobility practices at the ends of shifts. Descriptive statistics summarized nurse and patient characteristics and mobility barriers.

RESULTS

Patients were deemed ready to begin mobility within a mean (SD) of 41.5 (34.8) hours after oral endotracheal intubation. Two-thirds of nurses reported that they never or rarely got these patients out of bed. Only 12.4% of patients had a clinician's activity order. Common patient-related barriers were uncooperative behavior (21.9%) and active medical issues (15%), even in patients who met mobility criteria. Nurse-related barriers were concerns for patient safety, specifically falls (14.3% of patients) and harm (9.5%). The environment of care posed very few barriers; nurses rarely mentioned that lack of help (13.3% of patients) or lack of clinician's activity order (5.7%) impeded mobility.

CONCLUSIONS

Mobility practices were nonexistent in these patients despite patients' being deemed ready to begin out-of-bed activities. Nurses must be attentive to their unit's mobility culture to overcome these barriers.
