Staged Implementation of Awakening and Breathing, Coordination, Delirium Monitoring and Management, and Early Mobilization Bundle Improves Patient Outcomes and Reduces Hospital Costs

Preventive effects of early mobilisation on delirium incidence in critically ill patients: systematic review and meta-analysis

OBJECTIVE

To evaluate whether early mobilisation can reduce the incidence of delirium in critically ill patients and to assess the methodological quality of published studies.

METHODS

Three electronic databases, PubMed, Embase and the Cochrane Library, were searched for relevant studies published up to 2 March 2024. Articles were screened independently by two reviewers, based on inclusion and exclusion criteria, and a meta-analysis was performed using RevMan 5.3 software with a random-effects model.

RESULTS

A total of 18 studies (intervention group: 1794 participants, control group: 2129 participants) were included in the systematic review, with 18 studies included in the meta-analysis. Early mobilisation was found to reduce the risk of delirium in critically ill populations, with a pooled odds ratio of 0.65 (95% confidence interval [CI] 0.49-0.86; P = 0.003; I2 = 59%). Additionally, two studies found that early mobilisation did not change the duration of delirium in critically ill populations, with a pooled mean difference of -1.53 (95% CI -3.48 to 0.41; P = 0.12; I2 = 37%). Subgroup analysis revealed that early mobilisation maintained its preventive effect on delirium in the before/after intervention studies, studies published before 2018 and studies with a moderate methodological rating.

CONCLUSION

As a nonpharmacological intervention, early mobilisation may help reduce the risk of delirium and shorten its duration in critically ill patients compared with standard treatment and may potentially become a novel strategy for delirium prevention in future intensive care unit settings.

A comprehensive assessment tool of acute-phase rehabilitation is associated with clinical outcomes in patients after cardiovascular surgery

Perme intensive care unit (ICU) mobility score is a comprehensive mobility assessment tool; however, its usefulness and validity for patients after cardiovascular surgery remain unclear. We investigated the association between the Perme Score and clinical outcomes after cardiovascular surgery. We retrospectively enrolled 249 consecutive patients admitted to the ICU after cardiac and/or major vascular surgery. The Perme Score contains categories on mental status, potential mobility barriers, muscle strength and mobility level and was assessed within 2 days after surgery. The outcomes of physical recovery were the number of days until 100-m ambulation achievement and 6-min walk distance (6MWD) at hospital discharge. The endpoint was a composite outcome of all-cause mortality and/or all-cause unplanned readmission. We analyzed the associations of the Perme Score with physical recovery and the incidence of clinical events. After adjusting for clinical confounding factors, a higher Perme Score was an independent factor of earlier achievement of 100-m ambulation (hazard ratio: 1.039, 95% confidence interval [CI]: 1.012-1.066) and higher 6MWD (β: 0.293, P = .001). During the median follow-up period of 1.1 years, we observed an incidence rate of 19.4/100 person-years. In the multivariate Poisson regression analysis, a higher Perme Score was significantly and independently associated with lower rates of all-cause death/readmission (incident rate ratio: 0.961, 95% CI: 0.930-0.992). The Perme Score within 2 days after cardiovascular surgery was associated with physical recovery during hospitalization and clinical events after discharge. Thus, it may be useful for predicting clinical outcomes.

Music therapy in addition to music listening for the prevention of delirium in mechanically ventilated patients

Introduction

Delirium in mechanically ventilated patients has resulted in prolonged intensive care unit (ICU) and ventilator stay and higher mortality. Research has shown that a bundle containing sedation awakening and spontaneous breathing trials, appropriate choice of sedatives, early mobilization, and family engagement was associated with a reduced rate of delirium. Music listening and music therapy have also been studied, showing promising results for anxiety and pain control, but have not been studied in terms of preventing delirium.

Methods

As part of a quality improvement project, we implemented a protocol of music listening and music therapy for mechanically ventilated patients. The rate of delirium, ICU and ventilator lengths of stay, and mortality were compared between groups (n = 17 protocol, n = 50 control).

Results

There were no statistically significant differences in demographic characteristics, severity of illness, medical comorbidities, or cumulative doses of sedating medications between the groups. The rate of delirium between groups was not statistically significantly different (11.8% vs 16%, P = 0.70). Severity of illness based on APACHE IV score was statistically associated with mortality (estimate coefficient 0.03, P = 0.015), and use of dexmedetomidine was statistically associated with prolonged ICU and ventilator lengths of stay.

Conclusion

The music therapy and music listening protocol did not show a reduction of the delirium rate for mechanically ventilated patients.

Pharmacologic prophylaxis of postoperative delirium in elderly patients: A network meta-analysis of randomized controlled trials

BACKGROUND

The high incidence and mortality rates of postoperative delirium (POD) among elderly patients highlights the pressing need for tailored prophylactic strategies. Despite various pharmacologic prophylactic strategies have been reported effective, their overall benefit and safety remain unclear in the geriatric population. Our network meta-analysis (NMA) aimed to systematically evaluate and rank the effectiveness of various pharmacological interventions in preventing POD in elderly patients.

METHODS

We conducted an extensive search of PubMed, Embase, Cochrane Central Register of Controlled Trials, PsycINFO, and Google Scholar for randomized controlled trials (RCTs) published up to August 1, 2023. We included RCTs examining pharmacological prophylactic effects of POD in elderly patients. To extract data in alignment with predefined areas of interest, we employed the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. The primary outcome was the incidence of POD. For secondary outcomes, we evaluated tolerability through all-cause discontinuation or drop-out rates, as well as all-cause mortality.

RESULTS

Our analysis encompassed a total of 44 RCTs involving 11,178 patients. Out of these, 26 RCTs involved comparisons with placebo only. For delirium prevention, the treatment groups receiving atypical antipsychotics (odds ratio (OR) of 0.27 and 95% confidence interval (CI) of 0.12-0.58), haloperidol (OR of 0.42; 95% CI of 0.25-0.71), dexmedetomidine (OR of 0.51 and 95% CI of 0.37-0.71 and melatonergic agents (MMA) (OR of 0.57 and 95% CI of 0.33-0.98) had significantly lower rates of delirium compared to the placebo group. Notably, the atypical antipsychotics ranked as the most effective treatment. For tolerability, no statistically differences in rates of dropout discontinuation and all-cause mortality among groups allocated to the placebo or individual pharmacological treatments.

CONCLUSIONS

Based on indirect evidence, our network meta-analysis identified atypical antipsychotics, dexmedetomidine, MMA, and haloperidol as effective in preventing POD in the elderly, with atypical antipsychotics ranking highest. However, it is essential to note that these findings should be confirmed through further RCTs.

Comparison of SAT and SBT Conduct During the ABC Trial and PILOT Trial

BACKGROUND

Implementation of the "B" element-both spontaneous awakening trials (SATs) and spontaneous breathing trials (SBTs)-of the ABCDEF bundle improves the outcomes for mechanically ventilated patients. In 2021, the Pragmatic Investigation of optimal Oxygen Targets (PILOT) trial investigating optimal oxygenation targets in patients on mechanical ventilation was completed.

OBJECTIVES

To compare SAT and SBT conduct between a randomized controlled trial and current clinical care.

METHODS

The 2008 Awakening and Breathing Controlled (ABC) Trial (2003-2006) randomized mechanically ventilated patients to paired SATs and SBTs versus sedation per usual care plus SBTs. The PILOT trial (2018-2021) enrolled patients years later where SAT + SBT conduct was observed. We compared SAT and SBT conduct in ABC's interventional group (SAT + SBT; n = 167, 1140 patient days) to that in PILOT (n = 2083, 8355 patient days).

RESULTS

Spontaneous awakening trial safety screens were done in all 1140 ABC patient-days on sedation and/or analgesia and in 3889 of 4228 (92%) in PILOT. Spontaneous awakening trial safety screens were passed in 939 of 1140 (82%) instances in ABC versus only 1897 of 3889 (49%) in PILOT. Interestingly, SAT was performed in ≥95% of passed SAT safety screens in both trials and was passed in 837 of 895 (94%) in ABC versus 1145 of 1867 (61%) in PILOT. SBT safety screens were performed in all 983 ABC instances and 8031 of 8370 (96%) in PILOT. SBT safety screens were passed in 647 of 983 (66%) in ABC versus 4475 of 8031 (56%) in PILOT. Spontaneous breathing trial was performed in ≥93% of passed SBT safety screens in both trials and was passed in 319 of 603 (53%) in ABC versus 3337 of 4454 (75%) in PILOT.

CONCLUSION

This study compared SAT/SBT conduction in an ideal setting to real-world practice, 13 years later. Performance of SAT/SBT safety screens, SATs, and SBTs between a definitive clinical trial (ABC) as compared to current clinical care (PILOT) remained high.

Using Implementation Science to Assess Barriers to Agreement on Sedation Goal Setting and Assessment

OBJECTIVES

Sedation assessment and goal setting using a validated assessment tool are key components of the ICU Liberation bundle. Appropriate integration of these bundle elements into daily practice remains challenging. Understanding barriers is an important step toward implementation of these best practice bundle elements.

DESIGN

Two-phased explanatory mixed methods assessment carried out 2022-2023.

SETTING

Forty-bed quaternary PICU.

SUBJECTS

Bedside nurses and prescribers caring for mechanically ventilated patients on sedative infusions.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Forty-one nurses and 32 prescribers participated in the phase 1 pre-education assessments (2022). We identified lack of correlation between the providers' stated State Behavioral Scale (SBS) numerical goal and descriptive goal and hypothesized that this discrepancy was either due to a knowledge gap or disagreement on sedation goals. To investigate this hypothesis, we performed a phase 2 assessment (2022-2023), starting with a multipronged educational activity, followed by a repeat survey that included a qualitative interview. One hundred ninety nurses and 45 prescribers received the educational activity. Twenty-eight nurses and 22 prescribers participated in the phase 2 assessments with the qualitative interview. Although correlation of the sedation goal between providers improved, it remained poor. Subsequent qualitative interview data indicated that the reasons for persistent disagreement in the sedation goal for a given patient were related to individual providers' beliefs and attitudes toward sedation, rather than lack of understanding about using the SBS to set a target sedation goal.

CONCLUSIONS

Barriers to setting and managing daily patient sedation goal in the PICU extend beyond providers' knowledge gaps. An improved understanding of underlying barriers is essential for successful implementation of evidence-based sedation guidelines.

Sedation in the ICU

AbstractSedation practices are key to improving intensive care unit (ICU) outcomes. Adequate treatment of pain, minimization of sedation, delirium prevention, and improved patient interaction to ensure early rehabilitation and faster ventilator liberation are evidenced-based components of ICU care. Here we review components of appropriate ICU sedation including the use of multicomponent care bundles such as the ABCDEF bundle with a focus on changes in ICU practice that followed the Covid-19 pandemic.

Effect of an evidence-based early rehabilitation program on adult patients with venovenous extracorporeal membrane oxygenation: A cohort study

OBJECTIVES

To assess the efficacy of early rehabilitation program for VV-ECMO patients and observe the influence on the respiratory and skeletal muscles.

DESIGN

A cohort study.

SETTING

The study was conducted with VVECMO patients in a comprehensive ICU with 32 beds.

MAIN OUTCOME MEASURES

Ultrasound measurements were performed on each patients on day 1, 4, 7, 10, and 14, including diaphragmatic excursion (DE), diaphragmatic thickening fraction (DTF), intercostal muscle thickening fraction (ICMTF), thickness of the rectus femoris (RF), thickness of vastus intermedius (VI), and rectus femoris cross-sectional area (RF-CSA). Data on basic characteristics, results of ultrasound measurements, patients outcomes and adverse events were collected.

RESULTS

22 patients received usual rehabilitation measures were set as the control group and 23 patients underwent early rehabilitation program were set as the study group. There were no differences in diaphragmatic excursion, diaphragmatic thickening fraction, intercostal muscle thickening fraction, thickness of rectus femoris, thickness of vastus intermedius, rectus femoris cross-sectional area between two groups on day 1 after VV-ECMO treatment (P > 0.05). The variation of diaphragmatic thickening fraction and intercostal muscle thickening fraction decreased on the day 7 and 14 after treatment (P < 0.05). The variation of vastus intermedius thickness and rectus femoris cross-sectional area in the study group was less compared with those in the control group on day 4, 7, 10 and 14. The ECMO duration in the study group was shorter than that in the control group (12.00 [10.00-16.25] days vs. 8.00 [6.00-12.25] days, P = 0.002), but there was no difference in the duration of mechanical ventilation.

CONCLUSION

Early rehabilitation program can ameliorate muscle atrophy. We recommend implementation of our rehabilitation program in VV-ECMO patients. This program can improve skeletal muscle atrophy and dysfunction in patients with VV-ECMO effectively and perhaps improve quality of life for patients in the future.

IMPLICATIONS FOR CLINICAL PRACTICE

Early rehabilitation program put higher demands bedside nurses. It requires them to observe conditions of VVECMO patients closely, assess the feasibility of rehabilitation promptly, and monitor for any adverse reactions. Ultrasound measurement is a noninvasive and useful tool to assess muscle atrophy in ICU patients. Early rehabilitation program can improve skeletal muscle atrophy and dysfunction in patients with VV-ECMO effectively.

Nurses' experiences of caring for nursing care-dependent ICU patients: A qualitative study

BACKGROUND

Nursing care dependency is a key, yet under-studied, nursing phenomenon. Patients in intensive care units are highly dependent on nursing care. Patients find dependency challenging, experiencing feelings of powerlessness and shame. The nurse-patient care relationship can influence patients' perception of dependency. Understanding how nurses experience their care for dependent patients is crucial, as nurses might not always grasp the impact of their actions on patients' dependency experiences.

AIM

To explore and interpret ICU nurses' perceptions of patients' nursing care dependency and their experiences in caring for nursing care-dependent patients.

STUDY DESIGN

A qualitative interpretative phenomenological study inspired by Merleau-Ponty's philosophical stance was conducted using focus groups with nurses who had been caring for adult patients for at least 6 months in ICUs of two hospitals. Data analysis followed Smith et al.'s guidance. Researchers immersed themselves in the transcripts, noted individual's experiences before transitioning to shared insights, coded significant phrases and generated themes and superordinate themes.

RESULTS

Four focus groups were conducted with 18 nurses with widely ranging ages and work experience. Four superordinate themes emerged: 'Time and context define dependency', 'Empathetic relationships help nurses understand patients' experience of dependency', 'Trusting nurse-patient relationships change the dependency experience' and 'Nurses' skills help patients to recover independence'.

CONCLUSION

This study increases critical care nurses' awareness of the overlooked phenomenon of caring for nursing care dependent patients and offers them an opportunity to reflect on their care for dependent patients and adapt it to patients' experiences. Further studies are needed with nurses and patients in different ICUs, cultures and countries, to gain a broader picture of experiences of nursing care dependency.

RELEVANCE TO CLINICAL PRACTICE

ICU nurses need strong relational skills to offer high-quality care for dependent patients, facilitating meaningful nurse-patient relationships based on empathy and trust. These relationships can significantly impact the patient's experience of dependence.

Impact of the restraint decision tree for physical restraint use in South Korean neurointensive care units

BACKGROUND

Nurses in neurointensive care units (NCUs) commonly use physical restraint (PR) to prevent adverse events like unplanned removal of devices (URDs) or falls. However, PR use should be based on evidenced decisions as it has drawbacks. Unfortunately, there is a lack of research-based PR protocol to support decision-making for nurses, especially for neurocritical patients.

AIM

This study developed a restraint decision tree for neurocritical patients (RDT-N) to assist nurses in making PR decisions. We assessed its effectiveness in reducing PR use and adverse events.

STUDY DESIGN

This study employed a baseline and post-intervention test design at a NCU with 19 beds and 45 nurses in a tertiary hospital in a metropolitan city in South Korea. Two-hundred and thirty-seven adult patients were admitted during the study period. During the intervention, nurses were trained on the RDT-N. PR use and adverse events between the baseline and post-intervention periods were compared.

RESULTS

Post-intervention, total number of restrained patients decreased (20.7%-16.3%; χ2 = 7.68, p = .006), and the average number of PR applied per restrained patient decreased (2.42-1.71; t = 5.74, p < .001). The most frequently used PR type changed from extremity cuff to mitten (χ2 = 397.62, p < .001). No falls occurred during the study periods. On the other hand, URDs at baseline were 18.67 cases per 1000 patient days in the high-risk group and 5.78 cases per 1000 patient days in the moderate-risk group; however, no URD cases were reported post-intervention.

CONCLUSIONS

The RDT-N effectively reduced PR use and adverse events. Its application can enhance patient-centred care based on individual condition and potential risks in NCUs.

RELEVANCE TO CLINICAL PRACTICE

Nurses can use the RDT-N to assess the need for PR in caring for neurocritical patients, reducing PR use and adverse events.

Early Mobilization Using a Mobile Patient Lift in the ICU: A Randomized Controlled Trial

OBJECTIVES

To ascertain whether a mobile patient lift facilitates early mobilization in ventilated ICU patients.

DESIGN

A single-center, open-label, randomized controlled trial.

SETTING

An academic ICU in Tokyo.

PATIENTS

Eighty patients were admitted to ICU and expected ventilation for at least 48 hours.

INTERVENTIONS

In the intervention group, in addition to the rehabilitation protocol received by the control group, patients were assisted in sitting, standing, transfers, and walking using the mobile patient lift.

MEASUREMENTS AND MAIN RESULTS

The intervention group predominantly stood faster than the control group (1.0 vs. 3.0 d, p < 0.01). The Intervention group also had significantly higher Functional Status Score-ICU scores at ICU discharge. However, the Medical Research Council score and Barthel index at discharge, length of ICU stay, and number of ventilator-free days did not differ between the two groups.

CONCLUSIONS

The use of mobile patient lifts facilitates the earlier standing of patients on ventilators. This may contribute to patients improved physical function in the ICU.

TRIAL REGISTRATION

The study protocol was registered with the University Hospital Medical Information Network (UMIN) under the registration number UMIN000044965. Registered July 30, 2021.

Multicentre implementation of a quality improvement initiative to reduce delirium in adult intensive care units: An interrupted time series analysis

PURPOSE

The ABCDEF bundle may improve delirium outcomes among intensive care unit (ICU) patients, however population-based studies are lacking. In this study we evaluated effects of a quality improvement initiative based on the ABCDEF bundle in adult ICUs in Alberta, Canada.

MATERIAL AND METHODS

We conducted a pre-post, registry-based clinical trial, analysed using interrupted time series methodology. Outcomes were examined via segmented linear regression using mixed effects models. The main data source was a population-based electronic health record.

RESULTS

44,405 consecutive admissions (38,400 unique patients) admitted to 15 general medical/surgical and/or neurologic adult ICUs between 2014 and 2019 were included. The proportion of delirium days per ICU increased from 30.24% to 35.31% during the pre-intervention period. After intervention implementation it decreased significantly (bimonthly decrease of 0.34%, 95%CI 0.18-0.50%, p < 0.01) from 33.48% (95%CI 29.64-37.31%) in 2017 to 28.74% (95%CI 25.22-32.26%) in 2019. The proportion of sedation days using midazolam demonstrated an immediate decrease of 7.58% (95%CI 4.00-11.16%). There were no significant changes in duration of invasive ventilation, proportion of partial coma days, ICU mortality, or potential adverse events.

CONCLUSIONS

An ABCDEF delirium initiative was implemented on a population-basis within adult ICUs and was successful at reducing the prevalence of delirium.

Predictors of Functional Decline Among Critically Ill Surgical Patients: A National Analysis

INTRODUCTION

Functional decline is associated with critical illness, though this relationship in surgical patients is unclear. This study aims to characterize functional decline after intensive care unit (ICU) admission among surgical patients.

METHODS

We performed a retrospective analysis of surgical patients admitted to the ICU in the Cerner Acute Physiology and Chronic Health Evaluation database, which includes 236 hospitals, from 2007 to 2017. Patients with and without functional decline were compared. Predictors of decline were modeled.

RESULTS

A total of 52,838 patients were included; 19,310 (36.5%) experienced a functional decline. Median ages of the decline and nondecline groups were 69 (interquartile range 59-78) and 63 (interquartile range 52-72) years, respectively (P < 0.01). The nondecline group had a larger proportion of males (59.1% versus 55.3% in the decline group, P < 0.01). After controlling for sociodemographic covariates, comorbidities, and disease severity upon ICU admission, patients undergoing pulmonary (odds ratio [OR] 6.54, 95% confidence interval [CI] 2.67-16.02), musculoskeletal (OR 4.13, CI 3.51-4.87), neurological (OR 2.67, CI 2.39-2.98), gastrointestinal (OR 1.61, CI 1.38-1.88), and skin and soft tissue (OR 1.35, CI 1.08-1.68) compared to cardiovascular surgeries had increased odds of decline.

CONCLUSIONS

More than one in three critically ill surgical patients experienced a functional decline. Pulmonary, musculoskeletal, and neurological procedures conferred the greatest risk. Additional resources should be targeted toward the rehabilitation of these patients.

Feasibility and Inter-rater Reliability of the Japanese Version of the Intensive Care Unit Mobility Scale

Purpose The purpose of this study was to verify the feasibility and inter-rater reliability of the Japanese version of the Intensive Care Unit Mobility Scale (IMS). Methods A prospective observational study was conducted at two intensive care units (ICUs) in Japan. The feasibility of the Japanese version of the IMS was assessed by 25 ICU staff (12 physical therapists and 13 nurses) using a 10-item questionnaire. Inter-rater reliability was assessed by two experienced physical therapists and two experienced nurses working with 100 ICU patients using the Japanese version of the IMS. Results In the questionnaire survey assessing feasibility, a high agreement rate was shown in 8 out of the 10 questions. All respondents could complete the IMS evaluation, and most respondents were able to complete the scoring of the IMS in a short time. The inter-rater reliability of the Japanese version of the IMS on the first day of physical therapy for ICU patients was 0.966 (95% CI: 9.94-9.99) for the weighted kappa coefficient and 0.985 (95% CI: 9.97-9.99) on the ICU discharge date assessment. The weighted κ coefficient showed an "almost perfect agreement" of 0.8 or higher. Conclusion The Japanese version of the IMS is a feasible tool with strong inter-rater reliability for the measurement of physical activity in ICU patients.

Clinical Impact of the Implementation Strategies Used to Apply the 2013 Pain, Agitation/Sedation, Delirium or 2018 Pain, Agitation/Sedation, Delirium, Immobility, Sleep Disruption Guideline Recommendations: A Systematic Review and Meta-Analysis

OBJECTIVES

To summarize the effectiveness of implementation strategies for ICU execution of recommendations from the 2013 Pain, Agitation/Sedation, Delirium (PAD) or 2018 PAD, Immobility, Sleep Disruption (PADIS) guidelines.

DATA SOURCES

PubMed, CINAHL, Scopus, and Web of Science were searched from January 2012 to August 2023. The protocol was registered with PROSPERO (CRD42020175268).

STUDY SELECTION

Articles were included if: 1) design was randomized or cohort, 2) adult population evaluated, 3) employed recommendations from greater than or equal to two PAD/PADIS domains, and 4) evaluated greater than or equal to 1 of the following outcome(s): short-term mortality, delirium occurrence, mechanical ventilation (MV) duration, or ICU length of stay (LOS).

DATA EXTRACTION

Two authors independently reviewed articles for eligibility, number of PAD/PADIS domains, quality according to National Heart, Lung, and Blood Institute assessment tools, implementation strategy use (including Assess, prevent, and manage pain; Both SAT and SBT; Choice of analgesia and sedation; Delirium: assess, prevent, and manage; Early mobility and exercise; Family engagement and empowerment [ABCDEF] bundle) by Cochrane Effective Practice and Organization of Care (EPOC) category, and clinical outcomes. Certainty of evidence was assessed using Grading of Recommendations Assessment, Development, and Evaluation.

DATA SYNTHESIS

Among the 25 of 243 (10.3%) full-text articles included ( n = 23,215 patients), risk of bias was high in 13 (52%). Most studies were cohort ( n = 22, 88%). A median of 5 (interquartile range [IQR] 4-7) EPOC strategies were used to implement recommendations from two (IQR 2-3) PAD/PADIS domains. Cohort and randomized studies were pooled separately. In the cohort studies, use of EPOC strategies was not associated with a change in mortality (risk ratio [RR] 1.01; 95% CI, 0.9-1.12), or delirium (RR 0.92; 95% CI, 0.82-1.03), but was associated with a reduction in MV duration (weighted mean difference [WMD] -0.84 d; 95% CI, -1.25 to -0.43) and ICU LOS (WMD -0.77 d; 95% CI, -1.51 to 0.04). For randomized studies, EPOC strategy use was associated with reduced mortality and MV duration but not delirium or ICU LOS.

CONCLUSIONS

Using multiple implementation strategies to adopt PAD/PADIS guideline recommendations may reduce mortality, duration of MV, and ICU LOS. Further prospective, controlled studies are needed to identify the most effective strategies to implement PAD/PADIS recommendations.

Description of an individualised delirium intervention in intensive care units for critically ill patients delivered by an artificial intelligence-assisted system: using the TIDieR checklist

Background

Delirium is a preventable and reversible complication for intensive care unit (ICU) patients, which can be linked to negative outcomes. Early intervention to cope with the risk factors of delirium is necessary. Yet no specific description of the Artificial Intelligence Assisted Prevention and Management for Delirium (AI-AntiDelirium) following the Template for Intervention Description and Replication (TIDieR) checklist was reported. This is the first study to describe a detailed process for the development of an evidence-based delirium intervention.

Aims

To describe an individualised delirium intervention which is delivered by an artificial intelligence-assisted system in the ICU for critically ill patients.

Methods and results

The TIDieR checklist improved the description of ICU delirium interventions, including several key features for improved implementation of the intervention. This descriptive research describes the AI-assisted ICU delirium interventions for improving cognitive load and adherence of nurses and reducing ICU delirium incidence. Following the TIDieR checklist, we standardised the flow chart of ICU delirium assessment tools; formed an evaluation sheet of ICU delirium risk factors; and translated the evidence-based ABCDEF bundle intervention into practice. Therefore, nurses and researchers would benefit from replicating the interventions for clinical use or experimental research.

Conclusions

The TIDieR checklist provided a systematic approach for reporting the complex ICU delirium interventions delivered in a clinical interventional trial, which contributes to the nursing practice policy for the standardisation of interventions.

From bedside to recovery: exercise therapy for prevention of post-intensive care syndrome

BACKGROUND

As advancements in critical care medicine continue to improve Intensive Care Unit (ICU) survival rates, clinical and research attention is urgently shifting toward improving the quality of survival. Post-Intensive Care Syndrome (PICS) is a complex constellation of physical, cognitive, and mental dysfunctions that severely impact patients' lives after hospital discharge. This review provides a comprehensive and multi-dimensional summary of the current evidence and practice of exercise therapy (ET) during and after an ICU admission to prevent and manage the various domains of PICS. The review aims to elucidate the evidence of the mechanisms and effects of ET in ICU rehabilitation and highlight that suboptimal clinical and functional outcomes of ICU patients is a growing public health concern that needs to be urgently addressed.

MAIN BODY

This review commences with a brief overview of the current relationship between PICS and ET, describing the latest research on this topic. It subsequently summarises the use of ET in ICU, hospital wards, and post-hospital discharge, illuminating the problematic transition between these settings. The following chapters focus on the effects of ET on physical, cognitive, and mental function, detailing the multi-faceted biological and pathophysiological mechanisms of dysfunctions and the benefits of ET in all three domains. This is followed by a chapter focusing on co-interventions and how to maximise and enhance the effect of ET, outlining practical strategies for how to optimise the effectiveness of ET. The review next describes several emerging technologies that have been introduced/suggested to augment and support the provision of ET during and after ICU admission. Lastly, the review discusses future research directions.

CONCLUSION

PICS is a growing global healthcare concern. This review aims to guide clinicians, researchers, policymakers, and healthcare providers in utilising ET as a therapeutic and preventive measure for patients during and after an ICU admission to address this problem. An improved understanding of the effectiveness of ET and the clinical and research gaps that needs to be urgently addressed will greatly assist clinicians in their efforts to rehabilitate ICU survivors, improving patients' quality of survival and helping them return to their normal lives after hospital discharge.

Association between preoperative neutrophil-lymphocyte ratio, uric acid, and postoperative delirium in elderly patients undergoing degenerative spine surgery

PURPOSE

There are few reports regarding the association between the neutrophil-lymphocyte ratio (NLR), uric acid, and the development of postoperative delirium (POD) in patients who are undergoing spine surgeries. We investigated the associations between the NLR, uric acid as a natural antioxidant, and POD in elderly patients undergoing degenerative spine surgery.

PATIENTS AND METHODS

This was a single-center, observational, and retrospective study conducted in Japan. We enrolled 410 patients who underwent degenerative spine surgery. POD was diagnosed after the surgeries by psychiatrists, based on the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). We performed a multivariable logistic regression analysis to clarify whether the NLR and uric acid values were associated with the development of POD in the patients.

RESULTS

129 of the 410 patients were excluded from the analysis. Of the 281 patients (137 females, 144 males), 32 patients (11.4%) were diagnosed with POD. The multivariable logistic regression analysis revealed that the preoperative uric acid level (adjusted odds ratio [aOR]: 0.67, 95% confidence interval [CI]: 0.49-0.90, p = 0.008) and age (aOR: 1.09, 95% CI: 1.02-1.16, p = 0.008) were significantly associated with POD. The preoperative NLR (aOR: 0.82, 95% CI: 0.60-1.13, p = 0.227) and antihyperuricemic medication (aOR: 0.97, 95% CI: 0.24-3.82, p = 0.959) were not significantly associated with POD.

CONCLUSION

Our results demonstrated that in elderly patients undergoing degenerative spine surgery, the preoperative NLR was not significantly associated with POD, but a lower preoperative uric acid value was an independent risk factor for developing POD. Uric acid could have a neuroprotective impact on POD in patients with degenerative spine diseases.

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.

Post-intensive care syndrome: Recent advances and future directions

Post-intensive care syndrome comprises physical, cognitive, and mental impairments in patients treated in an intensive care unit (ICU). It occurs either during the ICU stay or following ICU discharge and is related to the patients' long-term prognosis. The same concept also applies to pediatric patients, and it can greatly affect the mental status of family members. In the 10 years since post-intensive care syndrome was first proposed, research has greatly expanded. Here, we summarize the recent evidence on post-intensive care syndrome regarding its pathophysiology, epidemiology, assessment, risk factors, prevention, and treatments. We highlight new topics, future directions, and strategies to overcome post-intensive care syndrome among people treated in an ICU. Clinical and basic research are still needed to elucidate the mechanistic insights and to discover therapeutic targets and new interventions for post-intensive care syndrome.

Advances in post intensive care unit care: A narrative review

As the treatment options, modalities and technology have grown, mortality in intensive care unit (ICU) has been on the decline. More and more patients are being discharged to wards and in the care of their loved ones after prolonged treatment at times and sometimes in isolation. These survivors have a lower life expectancy and a poorer quality of life. They can have substantial familial financial implications and an economic impact on the healthcare system in terms of increased and continued utilisation of services, the so-called post intensive care syndrome (PICS). But it is not only the patient who is the sufferer. The mental health of the loved ones and family members may also be affected, which is termed as PICS-family. In this review, we shall be reviewing the definition, epidemiology, clinical features, diagnosis and evaluation, treatment and follow up of PICS. We shall also focus on measures to prevent, rehabilitate and understand the ICU stay from patients’ perspective on how to redesign the ICU, post ICU care needs for a better patient outcome.

Evaluation of the Impact of ABCDEF Bundle Compliance Rates on Postintensive Care Syndrome: A Secondary Analysis Study

OBJECTIVES

This study aimed to examine the association between ABCDEF bundles and long-term postintensive care syndrome (PICS)-related outcomes.

DESIGN

Secondary analysis of the J-PICS study.

SETTING

This study was simultaneously conducted in 14 centers and 16 ICUs in Japan between April 1, 2019, and September 30, 2019.

PATIENTS

Adult ICU patients who were expected to be on a ventilator for at least 48 hours.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Bundle compliance for the last 24 hours was recorded using a checklist at 8:00 am The bundle compliance rate was defined as the 3-day average of the number of bundles performed each day divided by the total number of bundles. The relationship between the bundle compliance rate and PICS prevalence (defined by the 36-item Short Form Physical Component Scale, Mental Component Scale, and Short Memory Questionnaire) was examined. A total of 191 patients were included in this study. Of these, 33 patients (17.3%) died in-hospital and 48 (25.1%) died within 6 months. Of the 96 patients with 6-month outcome data, 61 patients (63.5%) had PICS and 35 (36.5%) were non-PICS. The total bundle compliance rate was 69.8%; the rate was significantly lower in the 6-month mortality group (66.6% vs 71.6%, p = 0.031). Bundle compliance rates in patients with and without PICS were 71.3% and 69.9%, respectively ( p = 0.61). After adjusting for confounding variables, bundle compliance rates were not significantly different in the context of PICS prevalence ( p = 0.56). A strong negative correlation between the bundle compliance rate and PICS prevalence ( r = -0.84, R 2 = 0.71, p = 0.035) was observed in high-volume centers.

CONCLUSIONS

The bundle compliance rate was not associated with PICS prevalence. However, 6-month mortality was lower with a higher bundle compliance rate. A trend toward a lower PICS prevalence was associated with higher bundle compliance in high-volume centers.

Return to work and health-related quality of life up to 1 year in patients hospitalized for COVID-19: the CO-FLOW study

BACKGROUND

Currently, evidence about the long-term consequences of COVID-19 on return to work and health-related quality of life (HRQoL) is limited. We evaluated return to work and its associations with baseline characteristics and physical and mental recovery over time in patients up to 1 year after hospitalization for COVID-19. Secondly, we aimed to evaluate the association between return to work and health-related quality of life (HRQoL).

METHODS

CO-FLOW, a multicenter prospective cohort study, enrolled adult participants hospitalized for COVID-19, aged ≥ 18 years within 6 months after hospital discharge. Return to work and HRQoL were collected at 3, 6, and 12 months after hospital discharge using the iMTA Productivity Cost Questionnaire and the 36-Item Short Form Health Survey, respectively. Data were collected between July 1, 2020, and September 1, 2022. Generalized estimating equations with repeated measurements were used to assess outcomes over time.

RESULTS

In the CO-FLOW study, 371 participants were employed pre-hospitalization. At 3, 6, and 12 months post-discharge, 50% (170/342), 29% (92/317), and 15% (44/295) of participants had not returned to work, and 21% (71/342), 21% (65/317), and 16% (48/295) only partially, respectively. ICU admission (adjusted odds ratio (95% confidence interval): 0.17 (0.10 to 0.30), p < 0.001), persistent fatigue (0.93 (0.90 to 0.97), p < 0.001), female sex (0.57 (0.36 to 0.90), p = 0.017), and older age (0.96 (0.93 to 0.98), p < 0.001) were independently associated with no return to work. ICU patients required a longer time to return to work than non-ICU patients. Patients who did not return or partially returned to work reported lower scores on all domains of HRQoL than those who fully returned.

CONCLUSIONS

One year after hospitalization for COVID-19, only 69% of patients fully returned to work, whereas 15% did not return and 16% partially returned to work. No or partial return to work was associated with reduced HRQoL. This study suggests that long-term vocational support might be needed to facilitate return to work.

Implementation of coordinated spontaneous awakening and breathing trials using telehealth-enabled, real-time audit and feedback for clinician adherence (TEACH): a type II hybrid effectiveness-implementation cluster-randomized trial

BACKGROUND

Intensive care unit (ICU) patients on mechanical ventilation often require sedation and analgesia to improve comfort and decrease pain. Prolonged sedation and analgesia, however, may increase time on mechanical ventilation, risk for ventilator associated pneumonia, and delirium. Coordinated interruptions in sedation [spontaneous awakening trials (SATs)] and spontaneous breathing trials (SBTs) increase ventilator-free days and improve mortality. Coordination of SATs and SBTs is difficult with substantial implementation barriers due to difficult-to-execute sequencing between nurses and respiratory therapists. Telehealth-enabled remote care has the potential to overcome these barriers and improve coordinated SAT and SBT adherence by enabling proactive high-risk patient monitoring, surveillance, and real-time assistance to frontline ICU teams.

METHODS

The telehealth-enabled, real-time audit and feedback for clinician adherence (TEACH) study will determine whether adding a telehealth augmented real-time audit and feedback to a usual supervisor-led audit and feedback intervention will yield higher coordinated SAT and SBT adherence and more ventilator-free days in mechanically ventilated patients than a usual supervisor-led audit and feedback intervention alone in a type II hybrid effectiveness-implementation cluster-randomized clinical trial in 12 Intermountain Health hospitals with 15 ICUs. In the active comparator control group (six hospitals), the only intervention is the usual supervisor-led audit and feedback implementation. The telehealth-enabled support (TEACH) intervention in six hospitals adds real-time identification of patients eligible for a coordinated SAT and SBT and consultative input from telehealth respiratory therapists, nurses, and physicians to the bedside clinicians to promote adherence including real-time assistance with execution. All intubated and mechanically ventilated patients ≥ 16 years of age are eligible for enrollment except for patients who die on the day of intubation or have preexisting brain death. Based on preliminary power analyses, we plan a 36-month intervention period that includes a 90-day run-in period. Estimated enrollment in the final analysis is up to 9900 mechanically ventilated patients over 33 months.

DISCUSSION

The TEACH study will enhance implementation science by providing insight into how a telehealth intervention augmenting a usual audit and feedback implementation may improve adherence to coordinated SAT and SBT and increase ventilator-free days.

Effect of early mobilisation on long-term cognitive impairment in critical illness in the USA: a randomised controlled trial

BACKGROUND

Patients who have received mechanical ventilation can have prolonged cognitive impairment for which there is no known treatment. We aimed to establish whether early mobilisation could reduce the rates of cognitive impairment and other aspects of disability 1 year after critical illness.

METHODS

In this single-centre, parallel, randomised controlled trial, patients admitted to the adult medical-surgical intensive-care unit (ICU), at the University of Chicago (IL, USA), were recruited. Inclusion criteria were adult patients (aged ≥18 years) who were functionally independent and mechanically ventilated at baseline and within the first 96 h of mechanical ventilation, and expected to continue for at least 24 h. Patients were randomly assigned (1:1) via computer-generated permuted balanced block randomisation to early physical and occupational therapy (early mobilisation) or usual care. An investigator designated each assignment in consecutively numbered, sealed, opaque envelopes; they had no further involvement in the trial. Only the assessors were masked to group assignment. The primary outcome was cognitive impairment 1 year after hospital discharge, measured with a Montreal Cognitive Assessment. Patients were assessed for cognitive impairment, neuromuscular weakness, institution-free days, functional independence, and quality of life at hospital discharge and 1 year. Analysis was by intention to treat. This trial was registered with ClinicalTrials.gov, number NCT01777035, and is now completed.

FINDINGS

Between Aug 11, 2011, and Oct 24, 2019, 1222 patients were screened, 200 were enrolled (usual care n=100, intervention n=100), and one patient withdrew from the study in each group; thus 99 patients in each group were included in the intention-to-treat analysis (113 [57%] men and 85 [43%] women). 65 (88%) of 74 in the usual care group and 62 (89%) of 70 in the intervention group underwent testing for cognitive impairment at 1 year. The rate of cognitive impairment at 1 year with early mobilisation was 24% (24 of 99 patients) compared with 43% (43 of 99) with usual care (absolute difference -19·2%, 95% CI -32·1 to -6·3%; p=0·0043). Cognitive impairment was lower at hospital discharge in the intervention group (53 [54%] 99 patients vs 68 [69%] 99 patients; -15·2%, -28·6 to -1·7; p=0·029). At 1 year, the intervention group had fewer ICU-acquired weaknesses (none [0%] of 99 patients vs 14 [14%] of 99 patients; -14·1%; -21·0 to -7·3; p=0·0001) and higher physical component scores on quality-of-life testing than did the usual care group (median 52·4 [IQR 45·3-56·8] vs median 41·1 [31·8-49·4]; p<0·0001). There was no difference in the rates of functional independence (64 [65%] of 99 patients vs 61 [62%] of 99 patients; 3%, -10·4 to 16·5%; p=0·66) or mental component scores (median 55·9 [50·2-58·9] vs median 55·2 [49·5-59·7]; p=0·98) between the intervention and usual care groups at 1 year. Seven adverse events (haemodynamic changes [n=3], arterial catheter removal [n=1], rectal tube dislodgement [n=1], and respiratory distress [n=2]) were reported in six (6%) of 99 patients in the intervention group and in none of the patients in the usual care group (p=0·029).

INTERPRETATION

Early mobilisation might be the first known intervention to improve long-term cognitive impairment in ICU survivors after mechanical ventilation. These findings clearly emphasise the importance of avoiding delays in initiating mobilisation. However, the increased adverse events in the intervention group warrants further investigation to replicate these findings.

FUNDING

None.

Neurorecovery after Critical COVID-19 Illness

With the hundreds of millions of people worldwide who have been, and continue to be, affected by pandemic coronavirus disease (COVID-19) and its chronic sequelae, strategies to improve recovery and rehabilitation from COVID-19 are critical global public health priorities. Neurologic complications have been associated with acute COVID-19 infection, usually in the setting of critical COVID-19 illness. Neurologic complications are also a core feature of the symptom constellation of long COVID and portend poor outcomes. In this article, we review neurologic complications and their mechanisms in critical COVID-19 illness and long COVID. We focus on parallels with neurologic disease associated with non-COVID critical systemic illness. We conclude with a discussion of how recent findings can guide both neurologists working in post-acute neurologic rehabilitation facilities and policy makers who influence neurologic resource allocation.

Neurological complications of sepsis

PURPOSE OF REVIEW

Sepsis, defined as life-threatening organ dysfunction caused by a dysregulated host response to infection, is a leading cause of hospital and ICU admission. The central and peripheral nervous system may be the first organ system to show signs of dysfunction, leading to clinical manifestations such as sepsis-associated encephalopathy (SAE) with delirium or coma and ICU-acquired weakness (ICUAW). In the current review, we want to highlight developing insights into the epidemiology, diagnosis, prognosis, and treatment of patients with SAE and ICUAW.

RECENT FINDINGS

The diagnosis of neurological complications of sepsis remains clinical, although the use of electroencephalography and electromyography can support the diagnosis, especially in noncollaborative patients, and can help in defining disease severity. Moreover, recent studies suggest new insights into the long-term effects associated with SAE and ICUAW, highlighting the need for effective prevention and treatment.

SUMMARY

In this manuscript, we provide an overview of recent insights and developments in the prevention, diagnosis, and treatment of patients with SAE and ICUAW.

Effect of an educational intervention on compliance with care bundle items to prevent ventilator-associated pneumonia

OBJECTIVES

We aimed to evaluate the effectiveness of our ventilator-associated pneumonia prevention bundle implemented by education of the nursing staff, and to describe the tendency of knowledge retention.

RESEARCH METHODOLOGY

A prospective, before-and-after study was performed. The ventilator-associated pneumonia prevention bundle was implemented through a single educational intervention of the nursing staff. The risk of ventilator-associated pneumonia over time was estimated using a Cox proportional cause-specific hazard model. Compliance to preventive measures was assessed at three time-points: before education, at three months and 12 months after education.

SETTING

A 29-bed mixed medical-surgical intensive care unit.

MAIN OUTCOME MEASURES

Ventilator-associate pneumonia incidence densities, the risk of ventilator-associated pneumonia, and compliance to preventive measures in the pre-implementation and post-implementation periods.

RESULTS

We analyzed the data of 251 patients. The incidence density of pneumonia decreased from 29.3/1000 to 15.3/1000 ventilator-days after the implementation of the prevention program. Patients in the post-implementation period had significantly lower risk to develop pneumonia (hazard ratio 0.34, 95 % confidence interval 0.19-0.61, p = 0.001). At 3 months of implementation, a significant improvement was detected to all the individual bundle components. Complete compliance increased from 16.2 % to 62.2 % (p < 0.001). Compliance with bundle components decreased to baseline levels after 12 months of implementation apart from head-of-bed elevation.

CONCLUSION

This study supports existing evidence that educational interventions improve compliance. The gained knowledge was well translated into clinical practice reflected by the decreasing ventilator-associated pneumonia rate. It may be assumed that a refresher educational session within 12 months after implementation is needed.

Enhancing the awakening to family engagement bundle with music therapy

Survivors of prolonged intensive care unit (ICU) admissions may present undesirable long-term outcomes. In particular, physical impairment and cognitive dysfunction have both been described in patients surviving episodes requiring mechanical ventilation and sedation. One of the strategies to prevent the aforementioned outcomes involves the implementation of a bundle composed by: (1) Spontaneous awakening trial; (2) Spontaneous breathing trial; (3) Choosing proper sedation strategies; (4) Delirium detection and management; (5) Early ICU mobility; and (6) Family engagement (ABCDEF bundle). The components of this bundle contribute in shortening length of stay on mechanical ventilation and reducing incidence of delirium. Since the first description of the ABCDEF bundle, other relevant therapeutic factors have been proposed, such as introducing music therapy. This mini-review describes the current evidence supporting the use of the ABCDEF bundle, as well as current knowledge on the implementation of music therapy.

Quality contract 'prevention of postoperative delirium in the care of elderly patients' study protocol: a non-randomised, pre-post, monocentric, prospective trial

INTRODUCTION

Postoperative delirium (POD) is seen in approximately 15% of elderly patients and is related to poorer outcomes. In 2017, the Federal Joint Committee (Gemeinsamer Bundesausschuss) introduced a 'quality contract' (QC) as a new instrument to improve healthcare in Germany. One of the four areas for improvement of in-patient care is the 'Prevention of POD in the care of elderly patients' (QC-POD), as a means to reduce the risk of developing POD and its complications.The Institute for Quality Assurance and Transparency in Health Care identified gaps in the in-patient care of elderly patients related to the prevention, screening and treatment of POD, as required by consensus-based and evidence-based delirium guidelines. This paper introduces the QC-POD protocol, which aims to implement these guidelines into the clinical routine. There is an urgent need for well-structured, standardised and interdisciplinary pathways that enable the reliable screening and treatment of POD. Along with effective preventive measures, these concepts have a considerable potential to improve the care of elderly patients.

METHODS AND ANALYSIS

The QC-POD study is a non-randomised, pre-post, monocentric, prospective trial with an interventional concept following a baseline control period. The QC-POD trial was initiated on 1 April 2020 between Charité-Universitätsmedizin Berlin and the German health insurance company BARMER and will end on 30 June 2023.

INCLUSION CRITERIA

patients 70 years of age or older that are scheduled for a surgical procedure requiring anaesthesia and insurance with the QC partner (BARMER). Exclusion criteria included patients with a language barrier, moribund patients and those unwilling or unable to provide informed consent. The QC-POD protocol provides perioperative intervention at least two times per day, with delirium screening and non-pharmacological preventive measures.

ETHICS AND DISSEMINATION

This protocol was approved by the ethics committee of the Charité-Universitätsmedizin, Berlin, Germany (EA1/054/20). The results will be published in a peer-reviewed scientific journal and presented at national and international conferences.

Impact of the COVID-19 pandemic on the diagnosis and treatment of onco-hematologic patients: a discussion paper

We do not know the precise figure for solid organ tumors diagnosed each year in Spain and it is therefore difficult to calculate whether there has been a decrease in cancer diagnoses as a consequence of the pandemic. Some indirect data suggest that the pandemic has worsened the stage at which some non-hematological neoplasms are diagnosed. Despite the lack of robust evidence, oncology patients seem more likely to have a poor outcome when they contract COVID-19. The antibody response to infection in cancer patients will be fundamentally conditioned by the type of neoplasia present, the treatment received and the time of its administration. In patients with hematological malignancies, the incidence of infection is probably similar or lower than in the general population, due to the better protective measures adopted by the patients and their environment. The severity and mortality of COVID-19 in patients with hematologic malignancies is clearly higher than the general population. Since the immune response to vaccination in hematologic patients is generally worse than in comparable populations, alternative methods of prevention must be established in these patients, as well as actions for earlier diagnosis and treatment. Campaigns for the early diagnosis of malignant neoplasms must be urgently resumed, post-COVID manifestations should be monitored, collaboration with patient associations is indisputable and it is urgent to draw the right conclusions to improve our preparedness to fight against possible future catastrophes.

The effect of the ABCDE/ABCDEF bundle on delirium, functional outcomes, and quality of life in critically ill patients: A systematic review and meta-analysis

BACKGROUND

The effect of the ABCDEF bundle (Assess, prevent, and manage pain; Both spontaneous awakening and spontaneous breathing trials; Choice of analgesia and sedation; Delirium: assess, prevent, and manage; Early mobility and exercise; and Family engagement and empowerment) on patient outcomes such as delirium is potentially optimised when the bundle is implemented in its entirety.

OBJECTIVE

To systematically synthesise the evidence on the effectiveness of the ABCDEF bundle delivered in its entirety on delirium, function, and quality of life in adult intensive care unit patients.

DESIGN

Systematic review and meta-analysis.

DATA SOURCE

Electronic databases including MEDLINE, CINAHL, PsycINFO, Web of Science, Cochrane Library, Joanna Briggs Institute's Evidence Based Practice, Australian New Zealand Clinical Trials Registry, and Embase were searched from 2000 until December 2021.

REVIEW METHODS

Inclusion criteria included (1) adult intensive care unit patients (2) studies that described the ABCDE or ABCDEF bundle in its entirety (3) studies that evaluated delirium, functional outcomes, or quality of life. Studies were excluded if they investigated long-term intensive care unit rehabilitation patients. Two reviewers independently screened records and full text, extracted data, and undertook quality appraisals with discrepancies discussed until consensus was reached. Random effects meta-analyses were conducted for delirium but was not possible for other outcomes. The Grading of Recommendations, Assessment, Development and Evaluation approach was used to assess the certainty of the synthesised findings of the body of evidence. The study protocol was registered on PROSPERO (CRD 42019126407).

RESULTS

A total of 18 studies (29,576 patients) were included in the descriptive synthesis. Meta-analysis of six studies (2000 patients) identified decreased delirium incidence following implementation of the ABCDEF bundle when compared with standard practice, (risk ratio = 0.57; CI, 0.36-0.90 p = 0.02) although heterogeneity was high (I² = 92%). When compared with standard practice, a meta-analysis of five studies (3418 patients) showed the ABCDEF bundle statistically significantly reduced the duration of intensive care unit delirium (mean difference (days) - 1.37, 95% CI -2.61 to -0.13 p = 0.03; I² 96%). Valid functional assessments were included in two studies, and quality of life assessment in one.

CONCLUSIONS

Although the evidence on the effect of the ABCDEF bundle delivered in its entirety is limited, positive patient delirium outcomes have been shown in this meta-analysis. As this meta-analysis was based on only 4736 patients in eight studies, further evidence is required to support its use in the adult intensive care unit.

Airway and Respiratory Devices in the Prevention of Ventilator-Associated Pneumonia

Ventilator-associated pneumonia (VAP) is the most common ICU-acquired infection among patients under mechanical ventilation (MV). It may occur in up to 50% of mechanically ventilated patients and is associated with an increased duration of MV, antibiotic consumption, increased morbidity, and mortality. VAP prevention is a multifaceted priority of the intensive care team. The use of specialized artificial airways and other devices can have an impact on the prevention of VAP. However, these devices can also have adverse effects, and aspects of their efficacy in the prevention of VAP are still a matter of debate. This article provides a narrative review of how different airway and respiratory devices may help to reduce the incidence of VAP.

Incidence, characteristics and risk factors of delirium in the intensive care unit: An observational study

AIMS AND OBJECTIVE

To investigate the incidence, characteristics and risk factors of delirium in the ICU.

BACKGROUND

Identifying the risk factors of delirium is important for early detection and to prevent adverse consequences.

DESIGN

An observational cohort study conducted according to STROBE Guidelines.

METHOD

The study was conducted with patients who stayed in ICU ≥24 h and were older than 18 years. Patients were assessed twice daily using the RASS and CAM-ICU until either discharge or death. Cumulative incidence was calculated. Demographic/clinical characteristics, length of stay and mortality were compared between patients with and without delirium. A logistic regression model was used to investigate risk factors.

RESULTS

The incidence of delirium was 31.8% and hypoactive type was the most frequent (41.5%). The median onset of delirium was 3 days (IQR = 2) with a mean duration of 5.27 ± 2.32 days. Patients with delirium were significantly older, had higher APACHE-II, SOFA and CPOT scores, higher blood urea levels, higher requirements for mechanical ventilation, sedation and physical restraints, longer stays in the ICU and higher mortality than those without delirium. The logistic regression analysis results revealed that a CPOT score ≥3 points (OR = 4.70, 95% CI: 1.05-20.93; p = .042), physical restraint (OR = 10.40, 95% CI: 2.75-39.27; p = .001) and ICU stay ≥7 days (OR = 7.26, 95% CI: 1.60-32.84; p = .010) were independent risk factors of delirium.

CONCLUSIONS

In this study, the incidence of delirium was high and associated with several factors. It is critical that delirium is considered by all members of the healthcare team, especially nurses, and that protocols are established for improvements.

RELEVANCE TO THE CLINICAL PRACTICE

Based on the results of this study, delirium could be decreased by preventing the presence of pain, prudent use of physical restraints and shortening the ICU stay.

Major Publications in the Critical Care Pharmacotherapy Literature: 2021

To summarize the most impactful articles relevant to the pharmacotherapy of critically ill adult patients published in 2021.

DATA SOURCE

PubMed/MEDLINE.

STUDY SELECTION

Randomized controlled trials, prospective studies, or systematic review/meta-analyses of adult critical care patients assessing a pharmacotherapeutic intervention and reporting clinical endpoints published between January 1, 2021, and December 31, 2021.

DATA EXTRACTION

Candidate articles were organized by clinical domain based on the emerging themes from all studies. A modified Delphi process was applied to obtain consensus on the most impactful publication within each clinical domain based on overall contribution to scientific knowledge and novelty to the literature.

DATA SYNTHESIS

The search revealed 830 articles, of which 766 were excluded leaving 64 candidate articles for the Delphi process. These 64 articles were organized by clinical domain including: emergency/neurology, cardiopulmonary, nephrology/fluids, infectious diseases, metabolic, immunomodulation, and nutrition/gastroenterology. Each domain required the a priori defined three Delphi rounds. The resultant most impactful articles from each domain included five randomized controlled trials and two systematic review/meta-analyses. Topics studied included sedation during mechanical ventilation, anticoagulation in COVID-19, extended infusion beta-lactams, interleukin-6 antagonists in COVID-19, balanced crystalloid resuscitation, vitamin C/thiamine/hydrocortisone in sepsis, and promotility agents during enteral feeding.

CONCLUSIONS

This synoptic review provides a summary and perspective of the most impactful articles relevant to the pharmacotherapy of critically ill adults published in 2021.

Informing the standardising of care for prolonged stay patients in the intensive care unit: A scoping review of quality improvement tools

OBJECTIVES

To inform design of quality improvement tools specific to patients with prolonged intensive care unit stay, we determined characteristics (format/content), development, implementation and outcomes of published multi-component quality improvement tools used in the intenisve care unit irrespective of length of stay.

RESEARCH METHODOLOGY

Scoping review searching electronic databases, trial registries and grey literature (January 2000 to January 2022).

RESULTS

We screened 58,378 citations, identifying 96 studies. All tools were designed for use commencing at intensive care unit admission except three tools implemented at 3, 5 or 14 days. We identified 32 studies of locally developed checklists, 28 goal setting/structured communication templates, 23 care bundles and 9 studies of mixed format tools. Most (43 %) tools were designed for use during rounds, fewer tools were designed for use throughout the ICU day (27 %) or stay (9 %). Most studies (55 %) reported process objectives i.e., improving communication, care standardisation, or rounding efficiency. Most common clinical processes quality improvement tools were used to standardise were sedation (62, 65 %), ventilation and weaning (55, 57 %) and analgesia management (58, 60 %). 44 studies reported the effect of the tool on patient outcomes. Of these, only two identified a negative effect; increased length of stay and increased days with pain and delirium.

CONCLUSION

Although we identified numerous quality improvement tools for use in the intensive care unit, few were designed to specifically address actionable processes of care relevant to the unique needs of prolonged stay patients. Tools that address these needs are urgently required.

Interprofessional Team Collaboration and Work Environment Health in 68 US Intensive Care Units

BACKGROUND

Safe, reliable, high-quality critical care delivery depends upon interprofessional teamwork.

OBJECTIVE

To describe perceptions of intensive care unit (ICU) teamwork and healthy work environments and evaluate whether perceptions vary by profession.

METHODS

In August 2015, Assessment of Interprofessional Team Collaboration Scale (AITCS) and the American Association of Critical-Care Nurses Healthy Work Environment Assessment Tool (HWEAT) surveys were distributed to all interprofessional members at the 68 ICUs participating in the ICU Liberation Collaborative. Overall scores range from 1 (needs improvement) to 5 (excellent).

RESULTS

Most of the 3586 surveys completed were from registered nurses (51.2%), followed by respiratory therapists (17.8%), attending physicians (10.5%), rehabilitation therapists (8.3%), pharmacists (4.9%), nursing assistants (3.1%), and physician trainees (4.1%). Overall, respondents rated teamwork and work environment health favorably (mean [SD] scores: AITCS, 3.92 [0.64]; HWEAT, 3.45 [0.79]). The highest-rated AITCS domain was "partnership/shared decision-making" (mean [SD], 4.00 [0.63); lowest, "coordination" (3.67 [0.80]). The highest-scoring HWEAT standard was "effective decision-making" (mean [SD], 3.60 [0.79]); lowest, "meaningful recognition" (3.30 [0.92]). Compared with attending physicians (mean [SD] scores: AITCS, 3.99 [0.54]; HWEAT, 3.48 [0.70]), AITCS scores were lower for registered nurses (3.91 [0.62]), respiratory therapists (3.86 [0.76]), rehabilitation therapists (3.84 [0.65]), and pharmacists (3.83 [0.55]), and HWEAT scores were lower for respiratory therapists (3.38 [0.86]) (all P ≤ .05).

CONCLUSIONS

Teamwork and work environment health were rated by ICU team members as good but not excellent. Care coordination and meaningful recognition can be improved.

The use of mechanical restraint in critical care units: Characterisation, application standards and related factors. Results of a multicentre study

OBJECTIVES

To describe and characterise the use of mechanical restraint (MR) in critical care units (CCU) in terms of frequency and quality of application and to study its relationship with pain/agitation-sedation/delirium, nurse:patient ratio and institutional involvement.

METHOD

Multicentre observational study conducted in 17 CCUs between February and May 2016. The observation time per CCU was 96 h. The main variables were the prevalence of restraint, the degree of adherence to MR recommendations, pain/agitation-sedation/delirium monitoring and institutional involvement (protocols and training of professionals).

RESULTS

A total of 1070 patients were included. The overall prevalence of restraint was 19.11%, in patients with endotracheal tube (ETT) 42.10% and in patients without ETT or artificial airway it was 13.92%. Adherence rates between 0% and 40% were obtained for recommendations related to non-pharmacological management and between 0% and 100% for those related to monitoring of ethical-legal aspects. The lower prevalence of restraint was correlated with adequate pain monitoring in non-communicative patients (P < .001) and with the provision of training for professionals (P = .020). An inverse correlation was found between the quality of the use of MR and its prevalence, both in the general group of patients admitted to CCU (r = -.431) and in the subgroup of patients with ETT (r = -.521).

CONCLUSIONS

Restraint is especially frequently used in patients with ETT/artificial airway, but is also used in other patients who may not meet the use profile. There is wide room for improvement in non-pharmacological alternatives to the use of MC, ethical and legal vigilance, and institutional involvement. Better interpretation of patient behaviour with validated tools may help limit use of MR.

Effectiveness of Nurse-Led Interventions for the Prevention of Mental Health Issues in Patients Leaving Intensive Care: A Systematic Review

This study aimed to evaluate the effectiveness of nurse-led interventions for the prevention of mental health disorders after intensive care unit discharge through a systematic review of the literature. The searches were conducted in the MEDLINE (via PubMed), CINAHL, PsycINFO, and Cochrane Library databases for studies pertaining to such interventions. Two independent reviewers analyzed the studies, extracted data, and assessed the quality of the evidence. Six eligible articles were identified, all of which were regarding post-traumatic stress disorder after intensive care unit discharge. Some of the interventions were conducted during the admission and some after the discharge. One study found that multimedia education during admission improved anxiety and depression one week after discharge. The remaining five studies concluded that nurse-led interventions did not prevent mental health disorders three months to one year after intensive care unit discharge. Our review revealed a paucity of research into the effectiveness of nurse-led interventions for the prevention of mental health disorders after intensive care unit discharge. The timing and the content of these interventions, and the adequate training of nurses, appear to be key factors. Therefore, multidisciplinary interventions are likely to be more effective than those led by nurses alone.

Mobilization and Rehabilitation Practice in ICUs During the COVID-19 Pandemic

BACKGROUND

Mobilization and acute rehabilitation are essential in the intensive care unit (ICU), with substantial evidence supporting their benefits. This study aimed to characterize ICU mobilization practices during the COVID-19 pandemic for patients with and without COVID-19.

METHODS

This was a secondary analysis of an international point prevalence study. All ICUs across the world were eligible to participate and were required to enroll all patients in each ICU on the survey date, 27 January 2021. The primary outcome was the achievement of mobilization at the level of sitting over the edge of the bed. Independent factors associated with mobilization, including COVID-19 infection, were analyzed by multivariable analysis.

RESULTS

A total of 135 ICUs in 33 countries participated, for inclusion of 1229 patients. Among patients who were not receiving mechanical ventilation (MV), those with COVID-19 infection were mobilized more than those without COVID-19 (60% vs. 34%, p < 0.001). Among patients who were receiving MV, mobilization was low in both groups (7% vs. 9%, p = .56). These findings were consistent irrespective of ICU length of stay. Multivariable analysis showed that COVID-19 infection was associated with achievement of mobilization in patients without (adjusted odds ratio [aOR] = 4.48, 95% confidence interval [CI] = 2.71-7.42) and with MV (aOR = 2.13, 95% CI = 1.00-4.51). Factors that prevented mobilization were prone positioning in patients without MV and continuous use of neuromuscular blockade and sedation agents in patients with MV, whereas facilitating factors were the presence of targets/goals in both groups.

CONCLUSION

Mobilization rates for ICU patients across the globe are severely low, with the greatest immobility observed in mechanically ventilated patients. Although COVID-19 is not an independent barrier to the mobilization of patients with or without MV, this study has highlighted the current lack of mobility practice for all ICU patients during the COVID-19 pandemic.(299 words).

Factors Associated With Spontaneous Awakening Trial and Spontaneous Breathing Trial Performance in Adults With Critical Illness: Analysis of a Multicenter, Nationwide, Cohort Study

BACKGROUND

Broad-scale adoption of spontaneous awakening trials (SATs) and spontaneous breathing trials (SBTs) into everyday practice has been slow, and uncertainty exists regarding what factors facilitate or impede their routine delivery.

RESEARCH QUESTION

What patient, practice, and pharmacologic factors are associated with SAT and SBT performance and to what extent do they predict overall SAT/SBT performance?

STUDY DESIGN AND METHODS

This secondary analysis used data collected from a national quality improvement collaborative composed of 68 diverse ICUs. Adults with critical illness adults who received mechanical ventilation and/or continuously infused sedative medications were included. We performed mixed-effects logistic regression modeling, created receiver operating characteristic curves, and calculated the area under the curve (AUC).

RESULTS

Included in the SAT and SBT analysis were 4,847 and 4,938 patients, respectively. In multivariable models controlling for admitting patient characteristics, factors independently associated with higher odds of a next-day SAT and SBT included physical restraint use (adjusted odds ratio [AOR], 1.63; 95% CI, 1.42-1.87; AOR, 1.83; 95% CI, 1.60-2.09), documented target sedation level (AOR, 1.68; 95% CI, 1.41-2.01; AOR, 1.46; 95% CI, 1.24-1.72), more frequent level of arousal assessments (AOR, 1.22; 95% CI, 1.03-1.43; AOR, 1.32; 95% CI, 1.13-1.54), and dexmedetomidine administration (AOR, 1.23; 95% CI, 1.05-1.45; AOR, 1.52; 95% CI, 1.27-1.80). Factors independently associated with lower odds of a next-day SAT and SBT included deep sedation/coma (AOR, 0.69; 95% CI, 0.60-0.80; AOR, 0.33; 95% CI, 0.28-0.37) and benzodiazepine (AOR, 0.83; 95% CI, 0.72-0.95; AOR, 0.67; 95% CI, 0.59-0.77) or ketamine (AOR, 0.34; 95% CI, 0.16-0.71; AOR, 0.40; 95% CI, 0.18-0.88) administration. Models incorporating admitting, daily, and unit variations displayed moderate discriminant accuracy in predicting next-day SAT (AUC, 0.73) and SBT (AUC, 0.72) performance.

INTERPRETATION

There are a number of modifiable factors associated with SAT/SBT performance that are amenable to the development and testing of implementation interventions.

Ventilator-associated pneumonia prevention in the Intensive care unit using Postpyloric tube feeding in China (VIP study): study protocol for a randomized controlled trial

BACKGROUND

Ventilator-associated pneumonia is a challenge in critical care and is associated with high mortality and morbidity. Although some consensuses on preventing ventilator-associated pneumonia are reached, it is still somewhat controversial. Meta-analysis has shown that postpyloric tube feeding may reduce the incidences of ventilator-associated pneumonia, which still desires high-quality evidence. This trial aims to evaluate the efficacy and safety profiles of postpyloric tube feeding versus gastric tube feeding.

METHODS/DESIGN

In this multicenter, open-label, randomized controlled trial, we will recruit 924 subjects expected to receive mechanical ventilation for no less than 48 h. Subjects on mechanical ventilation will be randomized (1:1) to receive postpyloric or gastric tube feeding and routine preventive measures simultaneously. The primary outcome is the proportion of patients with at least one ventilator-associated pneumonia episode. Adverse events and serious adverse events will be observed closely.

DISCUSSION

The VIP study is a large-sample-sized, multicenter, open-label, randomized, parallel-group, controlled trial of postpyloric tube feeding in China and is well-designed based on previous studies. The results of this trial may help to provide evidence-based recommendations for the prevention of ventilator-associated pneumonia.

Repositioning Strategies to Prevent Pressure Injuries in the ICU: Integrative Review on Implementation Factors

OBJECTIVE

To survey the literature to gain insight into nursing facilitators of and barriers to implementation of positioning/turning strategies to prevent hospital-acquired pressure injuries (PIs) in adult critical care patients.

DATA SOURCES

This integrative review surveyed literature across databases including PubMed, CINAHL, Embase, and Cochrane Library, and through hand searching.

STUDY SELECTION

Key terms included "pressure ulcer" OR "pressure sore*" OR "pressure injur*" AND "patient positioning" OR "turn" OR "turning" OR "patient repositioning" AND "critical care" OR "intensive care unit*" OR "inpatient*" AND "prevent*." Peer reviewed, English language articles published within the past 10 years were included. Inclusion and exclusion criteria narrowed the database yield to 432 articles. After title/abstract and full text review, 11 articles were included.

DATA EXTRACTION

Articles were appraised using the PRISMA flow diagram and the Johns Hopkins Nursing Evidence-Based Practice appraisal tool. Data was extracted and major themes were identified.

DATA SYNTHESIS

The identified themes were synthesized into factors that facilitated or impeded the nursing implementation of turning/repositioning strategies to prevent hospital-acquired PIs. Facilitators were the use of verbal cues and alerts to improve compliance and nursing education on PI prevention. Barriers to successful implementation were increased nursing workload or burden, lack of staff, and perceived hemodynamic instability in ICU patients.

CONCLUSIONS

Future interventions can be tailored to mitigate barriers and reinforce facilitators to improve nursing compliance with repositioning/turning strategies. Increased compliance with these measures could aid in PI prevention in adult ICU patients.
