Patients' and family members' dyadic experience of post-operative delirium in the intensive care unit: A qualitative study

BACKGROUND

Post-operative delirium is a complication with long-lasting consequences for both patients and their families. This is particularly true for those transferred to the intensive care unit after surgery, where the incidence of post-operative delirium is high, and patient outcomes are often poor. Despite the acknowledged role of family engagement in delirium management, previous research has mainly focused on patients, with limited exploration of the shared experiences between patients and family members.

AIM

This study aims to explore the experiences of patients and family members during episodes of post-operative delirium in the intensive care unit to better understand their unmet needs.

STUDY DESIGN

A qualitative descriptive study was conducted at a tertiary general hospital. Eighteen pairs of patients, their family members and two other family members were interviewed. Data were collected through face-to-face semi-structured interviews within the first week after patients' discharge from the intensive care unit and analysed using thematic analysis.

RESULTS

Four major themes emerged: (1) the dyadic relationship between patients and family members must be understood in the context of their shared emotional and behavioural experiences; (2) family's history may predispose patients to post-operative delirium; (3) family engagement may prevent the development of post-operative delirium; and (4) inadequate communication between health care providers and patients or families may negatively affect post-operative delirium outcomes.

CONCLUSIONS

Post-operative delirium presents significant emotional and physical challenges for both patients and their families. Addressing these challenges requires improved communication between health care providers and families, as well as strategies that emphasize early family support and collaboration in care.

RELEVANCE TO CLINICAL PRACTICE

Patients and their families should be considered a unit during post-operative delirium management, and earlier family engagement is essential. Health care systems should adapt intensive care unit practices to meet the dynamic needs of families, promoting more comprehensive support during critical care.

Exploring Cognitive Stimulation as a Therapy for the Prevention of Delirium in a Hospital Setting: A Narrative Review

Delirium is a highly prevalent and costly neuropsychiatric condition that affects up to 87% of critically ill hospitalized patients. It impacts various cognitive domains, including attention, memory, perception, and motor functions, with symptoms such as behavioral changes, hallucinations, slurred speech, visual impairments, and fatigue. Non-pharmacological interventions have been shown to reduce the incidence and duration of delirium, with strategies like reality orientation, cognitive stimulation, family support, and physical support. However, the scalability of these interventions in hospital settings is limited by resource constraints, low patient engagement, and the complexity of delivery. Digital technology-based cognitive stimulation offers a potential solution to these barriers, though evidence supporting its effectiveness is currently insufficient. This narrative literature review explores both traditional and novel digital technology-based cognitive stimulation techniques for the prevention and management of delirium in acute hospital settings.

Protocol for a meta-review of interventions to prevent and manage ICU delirium

INTRODUCTION

Intensive care unit (ICU) delirium is an acute brain dysfunction that affects up to 7 out of 10 patients admitted to ICUs. Patients who develop ICU delirium cannot think clearly, have trouble paying attention, do not understand what is happening around them and may see or hear things that are not there. ICU delirium increases the time patients spend in ICUs and hospitals and therefore healthcare costs. ICU delirium is also associated with increased mortality and dementia in the longer term. ICU delirium prevention and management strategies are likely to include both pharmacological and non-pharmacological components as part of a complex intervention, but it is unclear which components should be included. The objective of this meta-review is to systematically map the quantity and certainty of the available evidence from reviews and meta-analyses of randomised controlled trials (RCTs) of pharmacological and non-pharmacological interventions, which will be used to design a multicomponent intervention to prevent and manage ICU delirium.

METHODS AND ANALYSIS

A systematic search strategy was performed in MEDLINE (Ovid), Embase (Elsevier), Cochrane Database of Systematic Reviews, Scopus, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO and Web of Science (from inception to 26 September 2023), as well as Epistemonikos (from inception to 19 July 2023). We will include all critically ill adults (aged≥18 years) and any ICU delirium prevention or management intervention (pharmacological or non-pharmacological). For pharmacological interventions, we will include reviews of RCTs. For non-pharmacological interventions, we will consider reviews of RCTs, quasi-experimental and cohort studies. We will use the International Consensus Study (Del-COrS) core outcome set for research evaluating interventions to prevent or manage ICU delirium and synthesise our findings using quantitative data description methods. We will involve our Patient and Public Involvement group of people who experienced ICU delirium to develop and comment on such aspects as the research question, methodology and which outcomes are most important.

ETHICS AND DISSEMINATION

No ethical approval is required for this study. The results of this meta-review will be disseminated through peer-reviewed publications and conferences. They will also form part of an evidence map and logic model for the prevention and management of ICU delirium.

Family-Led Coaching of Patients During Weaning From Sedation and Mechanical Ventilation in the ICU

Background: ICU patients are weaned from sedation and mechanical ventilation through spontaneous awakening trials (SATs) and spontaneous breathing trials (SBTs). Weaning can be distressing for patients and their families. Family-led coaching could reassure patients and reduce stress for families by engaging them in patient care. This study developed and piloted a family-led coaching tool to support patients undergoing SATs/SBTs. Methods: Patient and family member dyads were recruited from 2 medical-surgical ICUs in Calgary, Canada (February 3-August 1, 2023). Surveys were administered to collect family (1) demographics, (2) anxiety and satisfaction with ICU care, (3) feedback on the tool, and (4) attitudes about family presence during SATs/SBTs (also collected from clinicians). Tool feasibility was determined by calculating the proportions of (1) eligible patients who were recommended for participation in the study by clinicians and (2) families approached who consented to participate in the study. Results: One thousand one hundred fifty patients were admitted to the study ICUs during the study period of which 819 received mechanical ventilation, and 42 were recommended by bedside clinicians for participation in the study. Twenty-five dyads were approached, 21 dyads consented to participate, and one withdrew consent before data collection. Of the enrolled families, 12 (60%) reported the coaching tool to be useful, and 5 (25%) recommended minor suggestions such as "shortening" the tool. Fourteen (70%) families reported positive experiences (through open-ended feedback) with being present for the SAT/SBT. State-Trait Anxiety Inventory (Y1) scores (scale range 20-80 points) significantly decreased in families from the first (pre coaching) to the second (post coaching) measures (mean decrease 8.2 points, SD 10.3, P = .001). All clinicians indicated they were comfortable with family presence and/or coaching during SATs/SBTs. Conclusion: Family-led coaching of patients during SATs/SBTs appears to be feasible, favorably perceived by families and clinicians, and potentially associated with lower family anxiety.

Comparative effectiveness of delirium recognition with and without a clinical decision assessment system on outcomes of hospitalized older adults: Cluster randomized controlled trial

BACKGROUND

Early recognition of delirium is essential for effective management, but it often goes unrecognized, resulting in adverse outcomes. Clinical decision support systems can enhance adherence to guidelines and improve patient outcomes. We developed a mobile-based clinical decision assessment tool (3D-DST) based on the 3-minute diagnostic interview for confusion assessment method-defined delirium (3D-CAM). Implementing the 3D-DST may enhance delirium recognition and adherence to interventions among healthcare professionals, potentially improving outcomes in older adults.

OBJECTIVE

To test whether improved recognition of delirium could lead to better clinical outcomes in older adults.

DESIGN

A cluster randomized controlled trial with pair-matching.

SETTING

A tertiary geriatric hospital.

PARTICIPANTS

Patients aged ≥65 years.

METHODS

Four general wards were paired and randomly assigned to the intervention group (two wards) or the control group (two wards). The intervention included routine delirium assessments by nurses using either the 3D-DST or the 3D-CAM, along with delirium prevention and intervention measures carried out by a multidisciplinary team. Outcomes measured included delirium incidence, duration, severity, length of stay, and adherence to the delirium assessment, prevention, and treatment protocol. A trained nursing researcher collected data on demographics, clinical characteristics, and primary and secondary outcomes.

RESULTS

211 eligible patients participated (106 in the intervention group and 105 in the control group), with 21 identified as delirium-positive using the 3D-DST. The median Charlson comorbidity index score among older adults in the intervention group was 1 (1-2), compared to 2 (1-3) in the control group (P = 0.032). Nurses' adherence to delirium assessment was significantly higher in the intervention group than in the control group (73 % vs. 31 %). The recognition rate of delirium among nurses was 89 % in the intervention group and 42 % in the control group. There were no statistically significant differences in delirium duration (6 [3-9] vs. 7 [2-14], P = 0.967), incidence (8.5 % vs. 11.4 %, P = 0.500), severity (2 [1-3] vs. 2 [1-4], P = 0.891) or length of hospital stay (15 [14-18] vs. 18 [13-22], P = 0.568) between the intervention and control groups.

CONCLUSIONS

The 3D-DST enhanced adherence to routine delirium recognition by nurses. However, effective strategies are urgently needed to strengthen multidisciplinary collaboration and enhance adherence to delirium management among healthcare professionals.

Analgosedation and delirium practices in critically ill patients in the Pan-American and Iberian setting, and factors associated with oversedation after the COVID-19 pandemic: Results from the PANDEMIC study

Oversedation has adverse effects on critically ill patients. The Analgosedation and Delirium Committee of the FEPIMCTI (Pan-American and Iberian Federation of Critical Care Medicine and Intensive Care) conducted a cross-sectional study through a survey addressed to ICU physicians: PANDEMIC (Pan-American and Iberian Study on the Management of Analgosedation and Delirium in Critical Care [fepImCti]). HYPOTHESIS: Worsening of these practices in the course of the pandemic and that continued afterwards, with further oversedation. OBJECTIVES: Perception of analgosedation and delirium practices in Pan-American and Iberian ICUs before, during and after the COVID-19 pandemic, and factors associated with persistent oversedation after the pandemic. Of the 1008 respondents, 25% perceived oversedation after the pandemic (95%CI 22.4-27.8). This perception was higher in South America (35.8%, P < .001). Main risk factor: habit acquired during the pandemic (adjusted OR [aOR] 3.16, 95%CI 2.24-4.45, P < .001). Main protective factor: delirium monitoring before the pandemic (aOR 0.70, 95%CI 0.50-0.98, P = .038). The factors identified in this study provide a basis for targeting future interventions.

A Critical Reappraisal of Haloperidol for Delirium Management in the Intensive Care Unit: Perspective from Psychiatry

Delirium is a complex neuropsychiatric syndrome with multifactorial pathophysiology, encompassing a wide range of neuropsychiatric symptoms, and its management remains a significant challenge in critical care. Although often managed with antipsychotics, like haloperidol, current research has predominantly focused on dopamine dysregulation as the primary driver of delirium, overlooking its broader neuroanatomical and neurochemical underpinnings. This has led to a majority of research focusing on haloperidol as a treatment for intensive care unit (ICU) delirium. Our review critically evaluates the role of haloperidol in ICU delirium management, particularly in light of recent large-scale randomized controlled trials (RCTs) that have primarily focused on delirium-free days and mortality as the primary endpoints. These studies highlight an limited understanding of the true nature of delirium treatment, which requires a broader, neuropsychiatric approach. We argue that future research should shift focus to neuropsychiatric symptoms such as agitation and psychosis and explore the clinical and functional benefits of reducing these distressing symptoms. Additionally, the stratification of delirium by subtypes and etiology, the enhancement of detection tools, and the adoption of multi-intervention and multi-disciplinary care approaches should be prioritized. Despite the methodological flaws in these studies, the findings support the safety of haloperidol in the ICU setting, with minimal risk of adverse events, particularly cardiac and neuropsychiatric. Moving forward, delirium research must integrate modern neuroscientific understanding and adopt more multi-disciplinary input and nuanced, patient-centered approaches to truly advance clinical care and outcomes.

Factors associated with ABCDEF bundle implementation for critically ill patients: An international cross-sectional survey in 54 countries

Objectives

This study investigated the implementation of the ABCDEF bundle and the factors associated with its implementation according to national income levels.

Methods

This study is cross-sectional research. We conducted a secondary analysis of an international 1-day point-prevalence study that investigated the implementation of the ABCDEF bundle in critically ill patients. All patients admitted to the ICU were eligible. This study was conducted across 135 ICUs in 54 countries, including data from 664 patients. Outcomes were categorized according to the income level of the country (high-income, middle-income, and low-income countries) in which each ICU was located. A multilevel generalized linear model was developed to identify the factors associated with ABCDEF bundle implementation for each income level.

Results

We identified 664 patients in 79 high-income countries, 278 in 26 middle-income countries, and 287 in 30 low-income countries ICUs. Implementation rates of the ABCDEF bundle were low for all income levels but varied. Few individuals completed the entire bundle on the survey date. Common factors associated with the implementation among all income levels were a multidisciplinary team approach for Element A (pain) and mechanical ventilation use for Element C (sedation), which were also associated with lower Element E (mobility). The existence of a protocol was frequently identified as a promoting factor associated with ABCDEF bundle implementation. The associated factors varied by income level; for example, dedicated intensivists were only identified in high-income countries, but not in middle-income countries or low-income countries.

Conclusions

The overall low ABCDEF bundle implementation rates necessitate action. As factors associated with its implementation vary according to national income level, tailored strategies are essential for improving ICU care quality.

Family involvement in preventing delirium in critically ill patients: A systematic review and meta-analysis

BACKGROUND

Humanized care is a novel concept in the prevention of delirium, with family involvement being a crucial component. Currently, there is controversy regarding the effectiveness of family involvement in preventing delirium among critically ill patients, and the impact of varying levels of family involvement on delirium prevention remains unclear.

OBJECTIVE

The purpose of this study is twofold: (a) to investigate the influence of family involvement on delirium among critically ill patients, and (b) to explore the effectiveness of different levels of family involvement in preventing delirium in these patients.

DESIGN

A systematic review and meta-analysis.

METHODS

From database inception to July 2024, a comprehensive search was conducted across PubMed, EMBASE, CINAHL, Web of Science, and the Cochrane CENTRAL database. Randomized controlled trials that examined family involvement were included in the review.

RESULTS

This review included a total of 11 randomized controlled trials, encompassing 3113 critically ill patients. Family involvement was found to significantly reduce the incidence of delirium among critically ill patients (RR = 0.46, 95%CI = 0.31 to 0.69), decrease the duration of delirium (WMD = -2.18, 95 % CI = -4.14 to -0.22), and shorten the length of Intensive Care Unit (ICU) stay (WMD = -1.46, 95%CI = -2.43 to -0.50). Three different levels of family involvement-direct participation in care (RR = 0.37, 95%CI = 0.26 to 0.51), family visits and companionship (RR = 0.56, 95 % CI = 0.25 to 1.25), and indirect participation (RR = 0.77, 95 % CI = 0.29 to 2.07)-varies in their effectiveness for delirium prevention.

CONCLUSIONS

Family involvement significantly impacts delirium prevention in critically ill patients. The effectiveness of delirium prevention varies depending on the level of family involvement, with direct participation of family members in caregiving demonstrating a more pronounced effect in reducing delirium incidence among critically ill patients.

Sex-Specific Validity of the PRE-DELIRIC Model and the E-PRE-DELIRIC Model for Predicting Delirium in Patients After Cardiac Surgery

BACKGROUND

Several risk prediction models are used in intensive care units (ICUs) to detect delirium risk.

OBJECTIVE

The aim of this study was to compare the sex-specific validity of the Prediction of Delirium in ICU patients (PRE-DELIRIC) and Early Prediction of Delirium in ICU patients (E-PRE-DELIRIC) models for predicting delirium in ICU patients after cardiac surgery.

METHODS

Retrospective data from electronic medical records of ICU patients who underwent cardiac surgery between January 2019 and December 2022 were examined. Both models were evaluated using sensitivity, specificity, and positive and negative predictive values based on the highest Youden index for female and male patients. Receiver operating characteristic curve analysis was performed.

RESULTS

Delirium incidence was 30.7% and 27.5% in female and male patients, respectively. In the PRE-DELIRIC model, the highest Youden index scores for female and male patients were 67.00 and 57.54, respectively, with sensitivities and specificities of 61% and 88%, and 72% and 79%, respectively. In the E-PRE-DELIRIC model, the highest scores for female and male patients were 14.25 and 14.05, with sensitivities and specificities of 78% and 50%, and 70% and 53%, respectively. The area under the curve of the PRE-DELIRIC model for female and male patients was 0.77 and 0.78, respectively, and that of the E-PRE-DELIRIC model was 0.67 and 0.63, respectively.

CONCLUSIONS

The PRE-DELIRIC model showed higher specificity and was more reliable for male patients, whereas the E-PRE-DELIRIC model demonstrated better sensitivity for female patients due to its inclusion of more female-sensitive factors. A combined approach is recommended for improved reliability and validity in delirium risk assessment in clinical settings.

Delirium in the ICU: how much do we know? A narrative review

Delirium in critical ill patients is a complex and common neurological syndrome in the intensive care unit (ICU) that is caused by a range of structural or functional abnormalities. ICU Delirium is associated with reduced compliance, prolonged hospital stays, greater use or delayed withdrawal of sedatives, higher rates and durations of mechanical ventilation, and higher rates of mortality. The aetiology and pathogenesis of ICU delirium are unclear, and the lack of better prediction, prevention, and treatment measures leads to a non-standardized control of delirium. By searching the relevant literature, we aim in this narrative review to describe progress in the pathogenesis, predictive biomarkers, diagnosis, and treatment of ICU delirium.

Practices of the ABCDEF care bundle in intensive care units as reported by nurses: A cross-sectional study from Turkey

BACKGROUND

Recent critical care guidelines recommended the evidence-based ABCDEF care bundle for intensive care unit (ICU) patients. However, limited information is available on the implementation of the bundle in Turkish ICUs.

AIM

To assess the current practices of the ABCDEF care bundle as reported by ICU nurses.

STUDY DESIGN

A cross-sectional study using a web-based survey was conducted. Researchers invited nurses with at least 1 year of ICU experience to participate by sending the link to the research questionnaires they created in Google Forms to the one ICU nurse association and one communication group of which they are members.

RESULTS

A total of 342 ICU nurses completed the survey. Although 92% of the participants performed pain assessments in their ICUs, 52.7% reported not using protocols. Based on the responses of the nurses, spontaneous awakening and breathing trials are performed in 88.8% and 92.4%, respectively, of ICUs. Fewer than half of the participants reported following a sedation protocol in their ICUs. Only 54.7% of ICU nurses surveyed reported routinely monitoring patients for delirium. It was reported that early mobilization was practised in 68.7% of ICUs, but non-ventilated patients were mobilized more frequently (70.2%), and 9.7% of ICUs had mobilization teams. Family members were actively involved in 95% of ICUs; however, 9.7% used dedicated staff to support families and 3.5% reported that their unit was open 24 h/day for visits.

CONCLUSIONS

While the implementation of most pain and sedation evaluations in ICUs were reported by nurses, many of them did not use structured delirium assessments. There is a need to encourage early mobilization programs and family participation.

RELEVANCE TO CLINICAL PRACTICE

Health institutions can improve patient care and outcomes by establishing and standardizing a protocol for each component of the ABCDEF care bundle in ICUs.

Delirium and Coronavirus Disease 2019: Looking Back, Moving Forward

During the coronavirus disease 2019 pandemic, crisis changes in clinical care increased rates of delirium in the intensive care unit (ICU). Deep sedation, unfamiliar environments with visitor restrictions, and such factors due to high workload and health system strain contributed to the occurrence of delirium doubling in the ICU. As the pandemic wanes, health care systems and ICU leadership must emphasize post-pandemic recovery, integrating lessons learned about delirium management, evidence-based care, and family involvement. Strategies to empower clinicians, creatively deliver care, and integrate families pave the way forward for a more holistic approach to patient care in the post-pandemic era.

A world-wide study on delirium assessments and presence of protocols

BACKGROUND

Delirium is a common complication of older people in hospitals, rehabilitation and long-term facilities.

OBJECTIVE

To assess the worldwide use of validated delirium assessment tools and the presence of delirium management protocols.

DESIGN

Secondary analysis of a worldwide one-day point prevalence study on World Delirium Awareness Day, 15 March 2023.

SETTING

Cross-sectional online survey including hospitals, rehabilitation and long-term facilities.

METHODS

Participating clinicians reported data on delirium, the presence of protocols, delirium assessments, delirium-awareness interventions, non-pharmacological and pharmacological interventions, and ward/unit-specific barriers.

RESULTS

Data from 44 countries, 1664 wards/units and 36 048 patients were analysed. Validated delirium assessments were used in 66.7% (n = 1110) of wards/units, 18.6% (n = 310) used personal judgement or no assessment, and 10% (n = 166) used other assessment methods. A delirium management protocol was reported in 66.8% (n = 1094) of wards/units. The presence of protocols for delirium management varied across continents, ranging from 21.6% (on 21/97 wards/units) in Africa to 90.4% (235/260) in Australia, similar to the use of validated delirium assessments with 29.6% (29/98) in Africa to 93.5% (116/124) in North America. Wards/units with a delirium management protocol [n = 1094/1664, 66.8%] were more likely to use a validated delirium test than those without a protocol [odds ratio 6.97 (95% confidence interval 5.289-9.185)]. The presence of a delirium protocol increased the chances for valid delirium assessment and, likely, evidence-based interventions.

CONCLUSION

Wards/units that reported the presence of delirium management protocols had a higher probability of using validated delirium assessments tools to assess for delirium.

Understanding patient and family experiences of critical care in Bangladesh and India: What are the priority actions to promote person-centred care?

Patients' experiences in the intensive care unit (ICU) can enhance or impair their subsequent recovery. Improving patient and family experiences on the ICU is an important part of providing high quality care. There is little evidence to guide how to do this in a South Asian critical care context. This study addresses this gap by exploring the experiences of critically ill patients and their families in ICUs in Bangladesh and India. We elicit suggestions for improvements from patients, families and staff and highlight examples of practices that support person-centred care. This multi-site hospital ethnography was carried out in five ICUs in government hospitals in Bangladesh and India, selected using purposive sampling. Qualitative data were collected using non-participant observation and semi-structured interviews and analysed using reflexive thematic analysis. A total of 108 interviews were conducted with patients, families, and ICU staff. Over 1000 hours of observation were carried out across the five study sites. We identified important mediators of patient and family experience that span many different aspects of care. Factors that promote person-centred care include access to ICU for families, support for family involvement in care delivery, clear communication with patients and families, good symptom management for patients, support for rehabilitation, and measures to address the physical, environmental and financial needs of the family. This study has generated a list of recommendations that can be used by policy makers and practitioners who wish to implement person-centred principles in the ICU.

Aripiprazole for treating delirium: A systematic review-Is it a valid yet understudied treatment?

BACKGROUND

Delirium is a neuropsychiatric condition that commonly occurs in medical settings, especially among older individuals. Despite the lack of strong evidence in the literature, haloperidol is considered the first-line pharmacological intervention. Unfortunately, its adverse effects can be severe, and psychiatrists are considering the use of alternative drugs targeting dopamine and serotonin domains (atypical antipsychotics). Among them, aripiprazole is considered to have one of the safest pharmacological profiles.

AIMS

The purpose of this study is to examine the studies on aripiprazole as a pharmacological treatment of delirium present in today's literature.

METHODS

We carried out systematic research of MedLine, PubMed, Cochrane, Embase, and ScienceDirect examining articles written between January 2002 and September 2023, including experimental studies published in peer-reviewed journals.

RESULTS

The 6 final included studies examined a total of 130 patients, showing a delirium resolution in a 7-day span of 73.8% of patients treated with aripiprazole.

CONCLUSIONS

Considering the limited data currently available, we can assert that aripiprazole is at least as efficient as haloperidol, the true point is that it has a far better tolerability and safety profile. Nonetheless, further studies are necessary to provide more compelling data, together with a more precise indication regarding minimum efficient dose, as the main limitations of our review are the very small sample size, the small percentage of subjects with preexisting dementia, and the fact that most studies used scales with low specificity for the examined condition.

Animation-guided family empowerment program on perioperative care after neurosurgery: A randomized controlled trial for preventing respiratory complications

Background

This study aimed to evaluate the effectiveness of using animation as education material for family empowerment program on perioperative care for caregivers whose children were to undergo neurosurgery.

Methods

A total of 204 caregivers were randomly assigned to either the face-to-face oral nursing educated group (Oral Group) or the animation-assisted nursing educated group (Animated Group). The nursing education primarily focused on instructing caregivers about the manual vibration method. The primary outcome of interest in this study was participants' knowledge level, collected by a 10-item questionnaire. Secondary outcomes included child patients' clinical data, including hospitalization days, treatments, and signs of pneumonia.

Results

Participants in the Animated Group exhibited significantly higher accuracy in perioperative care knowledge assessment, and patients in this group had a lower chance of requiring atomization therapy compared to the Oral Group.

Conclusions

The animation-assisted nursing education program effectively enhances pediatric caregivers' knowledge, reduces respiratory complications after surgery, and offers valuable insights for future studies on the use of such programs to instruct caregivers.

Impact of delirium intervention on cognitive load among nurses in the intensive care unit: A multi-centre cluster randomized controlled trial

BACKGROUND

High cognitive load in nurses is a common problem in the intensive care unit (ICU). However, it remains unclear what different types of cognitive load the ICU nurses have experienced during the implementation of delirium interventions.

AIM

To describe the characteristics and explore the effect of implementing a delirium intervention on the cognitive load of nurses working in the ICU.

METHODS

A cluster-randomized controlled clinical trial was conducted. Six ICUs were randomized in a 1:1 ratio, and eligible nurses from these units provided either a delirium bundle intervention in addition to usual care (27 nurses) or usual care alone. An instrument was used to measure different types of cognitive load (MDT-CL), assessing intrinsic, extraneous and germane cognitive load. The repeated measures analysis of variance was used to detect between-group differences.

RESULTS

Among these nurses, significant between-group differences were identified in terms of their overall (P < 0.001), intrinsic (P < 0.001) and extraneous (P < 0.001) cognitive load. There was no significant change observed in the germane cognitive load (P = 0.489) in the delirium intervention group.

CONCLUSION

It is important to understand how the implementation of a delirium intervention affects different types of cognitive load in nurses, in order that tailored strategies can be applied to reduce cognitive load in ICU nurses.

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.

A cluster-randomized controlled trial of a nurse-led artificial intelligence assisted prevention and management for delirium (AI-AntiDelirium) on delirium in intensive care unit: Study protocol

BACKGROUND

Delirium is a common complication among intensive care unit (ICU) patients that is linked to negative clinical outcomes. However, adherence to the Clinical Practice Guidelines for the Prevention and Management of Pain, Agitation/Sedation, Delirium, Immobility, and Sleep Disruption in Adult Patients in the ICU (PADIS guidelines), which recommend the use of the ABCDEF bundle, is sub-optimal in routine clinical care. To address this issue, AI-AntiDelirium, a nurse-led artificial intelligence-assisted prevention and management tool for delirium, was developed by our research team. Our pilot study yielded positive findings regarding the use of AI-AntiDelirium in preventing patient ICU delirium and improving activities of daily living and increasing intervention adherence by health care staff.

METHODS

The proposed large-scale pragmatic, open-label, parallel-group, cluster randomized controlled study will assess the impact of AI-AntiDelirium on the incidence of ICU delirium and delirium-related outcomes. Six ICUs in two tertiary hospitals in China will be randomized in a 1:1 ratio to an AI-AntiDelirium or a PADIS guidelines group. A target sample size of 1,452 ICU patients aged 50 years and older treated in the ICU for at least 24 hours will be included. The primary outcome evaluated will be the incidence of ICU delirium and the secondary outcomes will be the duration of ICU delirium, length of ICU and hospital stay, ICU and in-hospital mortality rates, patient cognitive function, patient activities of daily living, and ICU nurse adherence to the ABCDEF bundle.

DISCUSSION

If this large-scale trial provides evidence of the effectiveness of AI-AntiDelirium, an artificial intelligence-assisted system tool, in decreasing the incidence of ICU delirium, length of ICU and hospital stay, ICU and in-hospital mortality rates, patient cognitive function, and patient activities of daily living while increasing ICU nurse adherence to the ABCDEF bundle, it will have a profound impact on the management of ICU delirium in both research and clinical practice.

Antipsychotics and the QTc Interval During Delirium in the Intensive Care Unit: A Secondary Analysis of a Randomized Clinical Trial

Importance

Antipsychotic medications, often prescribed for delirium in intensive care units (ICUs), may contribute to QTc interval prolongation.

Objective

To determine whether antipsychotics increase the QTc interval in patients with delirium in the ICU.

Design, Setting, and Participants

An a priori analysis of a randomized clinical trial in medical/surgical ICUs within 16 centers across the US was conducted. Participants included adults with delirium in the ICU with baseline QTc interval less than 550 ms. The study was conducted from December 2011 to August 2017. Data analysis was performed from April 25 to August 18, 2021.

Interventions

Patients were randomized 1:1:1 to intravenous haloperidol, ziprasidone, or saline placebo administered twice daily until resolution of delirium, ICU discharge, or 14 days.

Main Outcomes and Measures

Twelve-lead electrocardiograms were used to measure baseline QTc before study drug initiation and telemetry was used to measure QTc before each subsequent dose of study drug. Unadjusted day-to-day changes in QTc were calculated and multivariable proportional odds regression was used to estimate the effects of antipsychotics vs placebo on next-day maximum QTc interval, adjusting for prespecified baseline covariates and potential interactions with sex. Safety end points, including the occurrence of torsade de pointes, were evaluated. All analyses were conducted based on the intention to treat principle.

Results

A total of 566 patients were randomized to haloperidol (n = 192), ziprasidone (n = 190), or placebo (n = 184). Median age was 60.1 (IQR, 51.4-68.7) years; 323 were men (57%). Baseline median QTc intervals across the groups were similar: haloperidol, 458.0 (IQR, 432.0-479.0) ms; ziprasidone, 451.0 (IQR, 424.0-472.0) ms; and placebo, 452.0 (IQR, 432.0-472.0) ms. From day 1 to day 2, median QTc changed minimally: haloperidol, -1.0 (IQR, -28.0 to 15.0) ms; ziprasidone, 0 (IQR, -23.0 to 20.0) ms; and placebo, -3.5 (IQR, -24.8 to 17.0) ms. Compared with placebo, neither haloperidol (odds ratio [OR], 0.95; 95% CI, 0.66-1.37; P = .78) nor ziprasidone (OR, 1.09; 95% CI, 0.75-1.57; P = .78) was associated with next-day QTc intervals. Effects were not significantly modified by sex (P = .41 for interaction). There were 2 occurrences of nonfatal torsade de pointes, both in the haloperidol group. Neither was associated with study drug administration.

Conclusions and Relevance

The findings of this trial suggest that daily QTc interval monitoring during antipsychotic use may have limited value in patients in the ICU with normal baseline QTc and few risk factors for QTc prolongation.

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.

Nociception assessment with videopupillometry in deeply sedated intensive care patients: Discriminative and criterion validations

BACKGROUND

Nociceptive assessment in deeply sedated patients is challenging. Validated instruments are lacking for this unresponsive population. Videopupillometry is a promising tool but has not been established in intensive care settings.

AIM/OBJECTIVE

To test the discriminate validity of pupillary dilation reflex (PDR) between non-noxious and noxious procedures for assessing nociception in non-neurological intensive care unit (ICU) patients and to test the criterion validity of pupil dilation using recommended PDR cut-off points to determine nociception.

METHODS

A single-centre prospective observational study was conducted in medical-surgical ICU patients. Two independent investigators performed videopupillometer measurements during a non-noxious and a noxious procedure, once a day (up to 7 days), when the patient remained deeply sedated (Richmond Agitation-Sedation Scale score: -5 or -4). The non-noxious procedures consisted of a gentle touch on each shoulder and the noxious procedures were endotracheal suctioning or turning onto the side. Bivariable and multivariable general linear mixed models were used to account for multiple measurements in same patients. Sensitivity and specificity, and areas under the curve of the receiver operating characteristic curve were calculated.

RESULTS

Sixty patients were included, and 305 sets of 3 measurements (before, during, and after), were performed. PDR was higher during noxious procedures than before (mean difference between noxious and non-noxious procedures = 31.66%). After testing all variables of patient and stimulation characteristics in bivariable models, age and noxious procedures were kept in the multivariable model. Adjusting for age, noxious procedures (coefficient = -15.14 (95% confidence interval = -20.17 to -15.52, p < 0.001) remained the only predictive factor for higher pupil change. Testing recommended cut-offs, a PDR of >12% showed a sensitivity of 65%, and a specificity of 94% for nociception prediction, with an area under the receiver operating curve of 0.828 (95% confidence interval = 0.779-0.877).

CONCLUSIONS

In conclusion, PDR is a potentially appropriate measure to assess nociception in deeply sedated ICU patients, and we suggest considering its utility in daily practices.

REGISTRATION

This study was not preregistered in a clinical registry.

TWEETABLE ABSTRACT

Pupillometry may help clinicians to assess nociception in deeply sedated ICU patients.

Monitoring delirium in the intensive care unit: Diagnostic accuracy of the CAM-ICU tool when performed by certified nursing assistants - A prospective multicenter study

BACKGROUND

Monitoring delirium in critically ill patients is recognized as a major challenge. Although involving certified nursing assistants could be a valuable help in this field, such strategy has never been formally investigated.

OBJECTIVES

Following theoretical training, we conducted a prospective multicenter study assessing the diagnostic accuracy of a CAM-ICU delirium screening strategy performed by CNAs in clinical settings, compared to parallel blinded evaluations conducted by nurses and physicians.

METHODS

From October 2020 to June 2022, adult intensive care patients admitted in three French University teaching hospitals with Richmond Agitation Sedation Scale ≥-2 were independently assessed for delirium by the three members of the care team (clinical nursing assistant, nurse and physician) using CAM-ICU in a random order. Physician's assessment served as the reference standard for comparisons.

RESULTS

We analyzed results from 268 triplets of CAM-ICU assessments performed sequentially on 203 patients. Prevalence of delirium was 22%. Compared to physician's assessments, clinical nursing assistants demonstrated a sensitivity (Se) of 88% CI95% [80-96] and a specificity (Sp) of 95% [92-98] in detecting delirium. There was no significant difference in the performance of clinical nursing assistants and nurses (Se = 90 % [82-97] p = 0.77, Sp = 98 % [95-100] p = 0.19). We observed high agreement between results obtained by physicians and clinical nursing assistants (ĸ = 0.82) and clinical nursing assistants performance remained consistent in the subgroups at higher risk of delirium.

CONCLUSION

Evaluation of the CAM-ICU by clinical nursing assistants is feasible and should be seen as an opportunity to increase routine monitoring of delirium in intensive care patients.

IMPLICATION FOR CLINICAL PRACTICE

Delirium is a severe and underestimated complication of intensive care unit stay. This study results demonstrate the great performance of trained clinical nursing assistants in detecting delirium using the CAM-ICU. Further research is needed to define the most effective role for clinical nursing assistants in the routine management of delirium in intensive care patients.

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.

Inclusion of frailty improved performance of delirium prediction for elderly patients in the cardiac intensive care unit (D-FRAIL): A prospective derivation and external validation study

BACKGROUND

The elderly patients admitted to cardiac intensive care unit (CICU) are at relatively high risk for developing delirium. A simple and reliable predictive model can benefit them from early recognition of delirium followed by timely and appropriate preventive strategies.

OBJECTIVE

To explore the role of frailty in delirium prediction and develop and validate a delirium predictive model including frailty for elderly patients in CICU.

DESIGN

A prospective, observational cohort study.

SETTINGS

CICU at China-Japan Friendship Hospital from March 1, 2022 to August 25, 2022 (derivation cohort); CICU at Beijing Anzhen Hospital affiliated to Capital Medical University from March 14, 2023 to May 8, 2023 (external validation cohort).

PARTICIPANTS

A total of 236 and 90 participants were enrolled in the derivation and external validation cohorts, respectively. Participants in the derivation cohort were assigned into either the delirium (n = 70) or non-delirium group (n = 166) based on the occurrence of delirium.

METHODS

The simplified Chinese version of the Confusion Assessment Method for the Diagnosis of Delirium in the Intensive Care Unit was used to assess delirium twice a day at 8:00-10:00 and 18:00-20:00 until the onset of delirium or discharge from the CICU. Frailty was assessed using the FRAIL scale during the first 24 h in the CICU. Other possible risk factors were collected prospectively through patient interviews and medical records review. After processing missing data via multiple imputations, univariate analysis and bootstrapped forward stepwise logistic regression were performed to select optimal predictors and develop the models. The models were internally validated using bootstrapping and evaluated comprehensively via discrimination, calibration, and clinical utility in both the derivation and external validation cohorts.

RESULTS

The study developed D-FRAIL predictive model using FRAIL score, hearing impairment, Acute Physiology and Chronic Health Evaluation-II score, and fibrinogen. The area under the receiver operating characteristic curve (AUC) was 0.937 (95% confidence interval [CI]: 0.907-0.967) and 0.889 (95%CI: 0.840-0.938) even after bootstrapping in the derivation cohort. Inclusion of frailty was demonstrated to improve the model performance greatly with the AUC increased from 0.851 to 0.937 (p < 0.001). In the external validation cohort, the AUC of D-FRAIL model was 0.866 (95%CI: 0.782-0.907). Calibration plots and decision curve analysis suggested good calibration and clinical utility of the D-FRAIL model in both the derivation and external validation cohorts.

CONCLUSIONS

For elderly patients in the CICU, FRAIL score is an independent delirium predictor and the D-FRAIL model demonstrates superior performance in predicting delirium.

Efficacy of haloperidol to decrease the burden of delirium in adult critically ill patients: the EuRIDICE randomized clinical trial

BACKGROUND

The role of haloperidol as treatment for ICU delirium and related symptoms remains controversial despite two recent large controlled trials evaluating its efficacy and safety. We sought to determine whether haloperidol when compared to placebo in critically ill adults with delirium reduces days with delirium and coma and improves delirium-related sequelae.

METHODS

This multi-center double-blind, placebo-controlled randomized trial at eight mixed medical-surgical Dutch ICUs included critically ill adults with delirium (Intensive Care Delirium Screening Checklist ≥ 4 or a positive Confusion Assessment Method for the ICU) admitted between February 2018 and January 2020. Patients were randomized to intravenous haloperidol 2.5 mg or placebo every 8 h, titrated up to 5 mg every 8 h if delirium persisted until ICU discharge or up to 14 days. The primary outcome was ICU delirium- and coma-free days (DCFDs) within 14 days after randomization. Predefined secondary outcomes included the protocolized use of sedatives for agitation and related behaviors, patient-initiated extubation and invasive device removal, adverse drug associated events, mechanical ventilation, ICU length of stay, 28-day mortality, and long-term outcomes up to 1-year after randomization.

RESULTS

The trial was terminated prematurely for primary endpoint futility on DSMB advice after enrolment of 132 (65 haloperidol; 67 placebo) patients [mean age 64 (15) years, APACHE IV score 73.1 (33.9), male 68%]. Haloperidol did not increase DCFDs (adjusted RR 0.98 [95% CI 0.73-1.31], p = 0.87). Patients treated with haloperidol (vs. placebo) were less likely to receive benzodiazepines (adjusted OR 0.41 [95% CI 0.18-0.89], p = 0.02). Effect measures of other secondary outcomes related to agitation (use of open label haloperidol [OR 0.43 (95% CI 0.12-1.56)] and other antipsychotics [OR 0.63 (95% CI 0.29-1.32)], self-extubation or invasive device removal [OR 0.70 (95% CI 0.22-2.18)]) appeared consistently more favorable with haloperidol, but the confidence interval also included harm. Adverse drug events were not different. Long-term secondary outcomes (e.g., ICU recall and quality of life) warrant further study.

CONCLUSIONS

Haloperidol does not reduce delirium in critically ill delirious adults. However, it may reduce rescue medication requirements and agitation-related events in delirious ICU patients warranting further evaluation.

Awakening and Breathing Coordination: A Mixed-Methods Analysis of Determinants of Implementation

Rationale: Routine spontaneous awakening and breathing trial coordination (SAT/SBT) improves outcomes for mechanically ventilated patients, but adherence varies. Understanding barriers to and facilitators of consistent daily use of SAT/SBT (implementation determinants) can guide the development of implementation strategies to increase adherence to these evidence-based interventions. Objectives: We conducted an explanatory, sequential mixed-methods study to measure variation in the routine daily use of SAT/SBT and to identify implementation determinants that might explain variation in SAT/SBT use across 15 intensive care units (ICUs) in urban and rural locations within an integrated, community-based health system. Methods: We described the patient population and measured adherence to daily use of coordinated SAT/SBT from January to June 2021, selecting four sites with varied adherence levels for semistructured field interviews. We conducted key informant interviews with critical care nurses, respiratory therapists, and physicians/advanced practice clinicians (n = 55) from these four sites between October and December 2021 and performed content analysis to identify implementation determinants of SAT/SBT use. Results: The 15 sites had 1,901 ICU admissions receiving invasive mechanical ventilation (IMV) for ⩾24 hours during the measurement period. The mean IMV patient age was 58 years, and the median IMV duration was 5.3 days (interquartile range, 2.5-11.9). Coordinated SAT/SBT adherence (within 2 h) was estimated at 21% systemwide (site range, 9-68%). ICU clinicians were generally familiar with SAT/SBT but varied in their knowledge and beliefs about what constituted an evidence-based SAT/SBT. Clinicians reported that SAT/SBT coordination was difficult in the context of existing ICU workflows, and existing protocols did not explicitly define how coordination should be performed. The lack of an agreed-upon system-level measure for tracking daily use of SAT/SBT led to uncertainty regarding what constituted adherence. The effects of the COVID-19 pandemic increased clinician workloads, impacting performance. Conclusions: Coordinated SAT/SBT adherence varied substantially across 15 ICUs within an integrated, community-based health system. Implementation strategies that address barriers identified by this study, including knowledge deficits, challenges regarding workflow coordination, and the lack of performance measurement, should be tested in future hybrid implementation-effectiveness trials to increase adherence to daily use of coordinated SAT/SBT and minimize harm related to the prolonged use of mechanical ventilation and sedation.

Enhanced recovery after surgery, current, and future considerations in head and neck cancer

Objectives

Review of the current and relevant literature to develop a list of evidence-based recommendations that can be implemented in head and neck surgical practices. To provide rationale for the multiple aspects of comprehensive care for head and neck surgical patients. To improve postsurgical outcomes for head and neck surgical patients.

Methods

Extensive review of the medical literature was performed and relevant studies in both the head and neck surgery and other surgical specialties were considered for inclusion.

Results

A total of 18 aspects of perioperative care were included in this review. The literature search included 276 publications considered to be the most relevant and up to date evidence. Each topic is concluded with recommendation grade and quality of evidence for the recommendation.

Conclusion

Since it's conception, enhanced recovery after surgery (ERAS) protocols have continued to push for comprehensive and evidence based postsurgical care to improve patient outcomes. Head and neck oncology is one of the newest fields to develop a protocol. Due to the complexity of this patient population and their postsurgical needs, a multidisciplinary approach is needed to facilitate recovery while minimizing complications. Current and future advances in head and neck cancer research will serve to strengthen and add new principles to a comprehensive ERAS protocol.

Clinical practice guideline recommendations for diagnosis and management of anxiety and depression in hospitalized adults with delirium: a systematic review

BACKGROUND

Delirium commonly occurs in hospitalized adults. Psychiatric disorders such as anxiety, depression, and post-traumatic stress disorder (PTSD) can co-occur with delirium, and can be recognized and managed by clinicians using recommendations found in methodological guiding statements called Clinical Practice Guidelines (CPGs). The specific aims of this review were to: [1] synthesize CPG recommendations for the diagnosis and management of anxiety, depression, and PTSD in adults with delirium in acute care; and [2] identify recent published literature in addition to those identified and reported in a 2017 review on delirium CPG recommendations and quality.

METHODS

MEDLINE, EMBASE, CINAHL, PsycINFO, and 21 sites on the Canadian Agency for Drugs and Technologies listed in the Health Grey Matters Lite tool were searched from inception to February 12, 2021. Selected CPGs focused on delirium in acute care, were endorsed by an international scientific society or governmental organization, and contained at least one recommendation for the diagnosis or management of delirium. Two reviewers independently extracted data in duplicate and independently assessed CPG quality using the AGREE-II tool. Narrative synthesis of CPG recommendations was conducted.

RESULTS

Title and abstract screening was completed on 7611 records. Full-text review was performed on 197 CPGs. The final review included 27 CPGs of which 7 (26%) provided recommendations for anxiety (4/7, 57%), depression (5/7, 71%), and PTSD (1/7, 14%) in delirium. Twenty CPGs provided recommendations for delirium only (e.g., assess patient regularly, avoid use of benzodiazepines). Recommendations for the diagnosis of psychiatric disorders with delirium included using evidence-based diagnostic criteria and standardized screening tools. Recommendations for the management of psychiatric disorders with delirium included pharmacological (e.g., anxiolytics, antidepressants) and non-pharmacological interventions (e.g., promoting patient orientation using clocks). Guideline quality varied: the lowest was Applicability (mean = 36%); the highest Clarity of Presentation (mean = 76%).

CONCLUSIONS

There are few available evidence-based CPGs to facilitate appropriate diagnosis and management of anxiety, depression, and PTSD in patients with delirium in acute care. Future guideline developers should incorporate evidence-based recommendations on the diagnosis and management of these psychiatric disorders in delirium.

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.

Failure of First Transition to Pressure Support Ventilation After Spontaneous Awakening Trials in Hypoxemic Respiratory Failure: Influence of COVID-19

OBJECTIVES

To describe the rate of failure of the first transition to pressure support ventilation (PSV) after systematic spontaneous awakening trials (SATs) in patients with acute hypoxemic respiratory failure (AHRF) and to assess whether the failure is higher in COVID-19 compared with AHRF of other etiologies. To determine predictors and potential association of failure with outcomes.

DESIGN

Retrospective cohort study.

SETTING

Twenty-eight-bedded medical-surgical ICU in a private hospital (Argentina).

PATIENTS

Subjects with arterial pressure of oxygen (AHRF to Fio2 [Pao2/Fio2] < 300 mm Hg) of different etiologies under controlled mechanical ventilation (MV).

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

We collected data during controlled ventilation within 24 hours before SAT followed by the first PSV transition. Failure was defined as the need to return to fully controlled MV within 3 calendar days of PSV start. A total of 274 patients with AHRF (189 COVID-19 and 85 non-COVID-19) were included. The failure occurred in 120 of 274 subjects (43.7%) and was higher in COVID-19 versus non-COVID-19 (49.7% and 30.5%; p = 0.003). COVID-19 diagnosis (odds ratio [OR]: 2.22; 95% CI [1.15-4.43]; p = 0.020), previous neuromuscular blockers (OR: 2.16; 95% CI [1.15-4.11]; p = 0.017) and higher fentanyl dose (OR: 1.29; 95% CI [1.05-1.60]; p = 0.018) increased the failure chances. Higher BMI (OR: 0.95; 95% CI [0.91-0.99]; p = 0.029), Pao2/Fio2 (OR: 0.87; 95% CI [0.78-0.97]; p = 0.017), and pH (OR: 0.61; 95% CI [0.38-0.96]; p = 0.035) were protective. Failure groups had higher 60-day ventilator dependence (p < 0.001), MV duration (p < 0.0001), and ICU stay (p = 0.001). Patients who failed had higher mortality in COVID-19 group (p < 0.001) but not in the non-COVID-19 (p = 0.083).

CONCLUSIONS

In patients with AHRF of different etiologies, the failure of the first PSV attempt was 43.7%, and at a higher rate in COVID-19. Independent risk factors included COVID-19 diagnosis, fentanyl dose, previous neuromuscular blockers, acidosis and hypoxemia preceding SAT, whereas higher BMI was protective. Failure was associated with worse outcomes.

Assessment of adequacy and appropriateness of pain management practice among trauma patients at the Ethiopian Aabet Hospital: A prospective observational study

INTRODUCTION

Pain is unpleasant sensory and emotional experiences associated with actual and/or potential tissue damage. It is the most common and prevalent reason for emergency departments (ED) visits with prevalence over 70% in the world.

AIM OF THE STUDY

The study aimed to assess the adequacy and appropriateness of pain management at Aabet Hospital, Addis Ababa, Ethiopia.

METHODS

A hospital-based prospective cross-sectional study was conducted at Aabet hospital from December 1, 2020 to March 30, 2021. Adult trauma patients having pain (at least score 1 on Numeric Rating Scale) with Glasgow Coma Scale score > 13 were eligible to participate in the study. The pain intensity was evaluated at the time of admission (o minute) and then at 60, 120, 180, and 240 minutes. The time of the first analgesics was registered. The adequacy and the appropriateness of the pain management were calculated through pain management index (PMI).

RESULTS

Two hundred thirty-two (232) participants were included in this study of which 126 (54.3%) were admitted due to road traffic accident followed by fall 44(19%). Only 21 (9.1%) study participants received the first analgesic treatment within 30 minutes while 27(11.6%) participants had no treatment at all within 240 minutes. The mean pain intensity score at admission was 5.55 ± 2.32 and reduced to 4.09 ± 2.69. Nearly half 110 (47.4%) of the study participants were treated inadequately (PMI (-) score). There was a weak and negative correlation between PMI and time to analgesia (r = - .159, p = 0.0001). The type of analgesia used, the time to analgesia, and the degree of pain may predict 65% of the variance in PMI score (R2 = 0.65, P = .001).

CONCLUSION

From the results of this study, it can be concluded that acute pain in trauma patients was under and inappropriately treated.

Critical Care Units in Malawi: A Cross-Sectional Study

Background

The global burden of critical illness falls disproportionately outside high-income countries. Despite younger patient populations with similar or lower disease severity, critical illness outcomes are poor outside high-income countries. A lack of data limits attempts to understand and address the drivers of critical care outcomes outside high-income countries.

Objectives

We aim to characterize the organization, available resources, and service capacity of public sector critical care units in Malawi and identify barriers to improving care.

Methods

We conducted a secondary analysis of the Malawi Emergency and Critical Care Survey, a cross-sectional study performed from January to February 2020 at all four central hospitals and a simple random sample of nine out of 24 public sector district hospitals in Malawi, a predominantly rural, low-income country of 19.6 million in southern Africa. Data from critical care units were used to characterize resources, processes, and barriers to care.

Findings

There were four HDUs and four ICUs across the 13 hospitals in the Malawi Emergency and Critical Care Survey sample. The median critical care beds per 1,000,000 catchment was 1.4 (IQR: 0.9 to 6.7). Absent equipment was the most common barrier in HDUs (46% [95% CI: 32% to 60%]). Stockouts was the most common barriers in ICUs (48% [CI: 38% to 58%]). ICUs had a median 3.0 (range: 2 to 8) functional ventilators per unit and reported an ability to perform several quality mechanical ventilation interventions.

Conclusions

Although significant gaps exist, Malawian critical care units report the ability to perform several complex clinical processes. Our results highlight regional inequalities in access to care and support the use of process-oriented questions to assess critical care capacity. Future efforts should focus on basic critical care capacity outside of urban areas and quantify the impact of context-specific variables on critical care mortality.

Critical Care of the Burn Patient

Care of the critically ill burned patient must integrate a multidisciplinary care team composed of burn care specialists. As resuscitative mortality decreases more patients are surviving to experience multisystem organ failure relating to complications of their injuries. Clinicians must be aware of physiologic changes following burn injury and the implicated impacts on management strategy. Promoting wound closure and rehabilitation should be the backdrop for which management decisions are made.

Comparison of resting energy expenditure measured with metabolic cart and calculated with predictive formulas in critically ill patients on mechanical ventilation

INTRODUCTION

The purpose was to compare the resting energy expenditure (REE) measured with the Q-NRG™+ metabolic-cart (MREE) with REE predicted by equations (the Harris-Benedict formula and an equation developed in ward, REE-HB and REE-W, respectively). We also aimed to assess the agreement of the measurements of oxygen consumption (V̇O₂) and carbon dioxide production (V̇CO₂) at different inspired fractions of oxygen (FiO₂).

METHODS

27 mechanically ventilated ICU patients were enrolled. V̇O₂ and V̇CO₂ were measured by Q-NRG™+ during breathing 40% and 60% FiO₂. MREE was compared with REE-W and REE-HB normalized for body weight.

RESULTS

V̇O₂ was 233.0 (95.2) ml/min and 217.5 (89.8) ml/min at FiO₂ 40% and 60%, respectively (NS). V̇CO₂ was 199.0 (91.7) ml/min at FiO₂ 40%, and 197.5 (85.5) ml/min at FiO₂ 60% (NS). The REE estimated from the equations was significantly different from the MREE. The best agreement was found for the Harris-Benedict equation without correction for stress-factors. Harris-Benedict equation corrected overestimates REE.

CONCLUSIONS

This new metabolic cart Q-NRG™+ provides a concordance of values for V̇O₂ and V̇CO₂ when measured at different FiO₂, and is a reliable tool for estimating energy expenditure and assessing the nutritional needs of the patient. This study demonstrates that the estimation of REE using predictive formulas does not allow accurate calculation of metabolic demands in ventilated intensive care patient. However, predictive equations allow for a rapid assessment of REE and calculation of the amount of energy derived from different substrates.

Early mobilization practice in intensive care units: A large-scale cross-sectional survey in China

BACKGROUND

The field of early rehabilitation has developed slowly in mainland China and there are limited data on the implementation of early mobilization (EM) practice in intensive care unit (ICUs) in China.

AIMS

To investigate the implementation of EM in ICUs in mainland China and to analyse its influencing factors.

DESIGN

A cross-sectional electronic survey was conducted in 444 ICUs across 11 provinces in China. Head nurses provided data on institutional characteristics and EM practice in ICUs. Logistic regression models were used to identify factors associated with the implementation of EM.

RESULTS

In all, 56.98% (253/444) of ICUs implemented EM with comprehensive or complete implementation in 86 ICUs. Of the 191 ICUs that did not use EM, 136 planned to implement EM in the near future. Of the 253 ICUs that used EM, 21.34% of ICUs implemented EM for all eligible patients, while 24.90% would evaluate and carry out EM within 48 h after ICU admission, 39.13% had collaborative EM teams, 34.39% reported the use of EM protocols, 14.63% reported multidisciplinary rounds and 17.39% had medical orders and charging standards for all EM activities. Only 18.18% of ICUs conducted frequent professional training for EM, and abnormal events occurred in 15.41% of ICUs during EM practice. Multivariate logistic regression analysis revealed that an economically strong province, the presence of a dedicated therapist team, more ICU beds and a higher staff-to-bed ratio favoured the implementation of EM. Furthermore, multidisciplinary rounds, well-established medical orders and charging standards, and a high frequency of professional training can lead to the comprehensive promotion and development of EM practice in ICUs.

CONCLUSIONS

Both the implementation rate and quality of EM practice for critically ill patients require improvement. EM practice in Chinese ICUs is still nascent and requires development in a variety of domains.

RELEVANCE FOR CLINICAL PRACTICE

To facilitate the implementation of EM in ICUs, more human resources, especially the involvement of a professional therapist team, should be deployed. In addition, health providers should actively organize multidisciplinary rounds and professional training and formulate appropriate EM medical orders and charging standards.

Pharmacologic Management of Intensive Care Unit Delirium and the Impact on the Duration of Delirium, Length of Intensive Care Unit Stay and 30-Day Mortality: A Network Meta-Analysis of Randomized-Control Trials

The present network meta-analysis was conducted to compare typical and atypical antipsychotics for the management of intensive care unit (ICU) delirium. The present meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Two investigators systematically searched electronic databases, including PubMed, EMBASE, and the Cochrane Library, for relevant studies in English from inception to February 15, 2023. The key terms used to search for relevant articles included "antipsychotic," "delirium," "randomized-controlled trials," and "efficacy." We used the term "randomized controlled trials (RCTs)" to limit the search to RCTs. The primary outcome was the duration of delirium in days. There were three predefined secondary outcomes included: mortality in 30 days, duration of mechanical ventilation in days, and length of ICU stay in days. A total of seven studies were included in the present meta-analysis. No significant difference was found between typical anti-psychotic, atypical anti-psychotic, and placebo in terms of duration of delirium, rate of mortality, duration of ICU stay, and duration of mechanical ventilation. In conclusion, this network meta-analysis comparing typical antipsychotic, atypical antipsychotic medications, and placebo on delirium in patients in the ICU did not find evidence that either typical or atypical antipsychotic medications led to a shorter duration of delirium. Patients who received treatment with typical or atypical antipsychotics and those who received a placebo had similar clinical outcomes, including mortality, length of stay in the ICU, and duration of ventilation.

Association of early mobility with the incidence of deep-vein thrombosis and mortality among critically ill patients: a post hoc analysis of PREVENT trial

BACKGROUND

This study assessed the mobility levels among critically ill patients and the association of early mobility with incident proximal lower-limb deep-vein thrombosis and 90-day mortality.

METHODS

This was a post hoc analysis of the multicenter PREVENT trial, which evaluated adjunctive intermittent pneumatic compression in critically ill patients receiving pharmacologic thromboprophylaxis with an expected ICU stay ≥ 72 h and found no effect on the primary outcome of incident proximal lower-limb deep-vein thrombosis. Mobility levels were documented daily up to day 28 in the ICU using a tool with an 8-point ordinal scale. We categorized patients according to mobility levels within the first 3 ICU days into three groups: early mobility level 4-7 (at least active standing), 1-3 (passive transfer from bed to chair or active sitting), and 0 (passive range of motion). We evaluated the association of early mobility and incident lower-limb deep-vein thrombosis and 90-day mortality by Cox proportional models adjusting for randomization and other co-variables.

RESULTS

Of 1708 patients, only 85 (5.0%) had early mobility level 4-7 and 356 (20.8%) level 1-3, while 1267 (74.2%) had early mobility level 0. Patients with early mobility levels 4-7 and 1-3 had less illness severity, femoral central venous catheters, and organ support compared to patients with mobility level 0. Incident proximal lower-limb deep-vein thrombosis occurred in 1/85 (1.3%) patients in the early mobility 4-7 group, 7/348 (2.0%) patients in mobility 1-3 group, and 50/1230 (4.1%) patients in mobility 0 group. Compared with early mobility group 0, mobility groups 4-7 and 1-3 were not associated with differences in incident proximal lower-limb deep-vein thrombosis (adjusted hazard ratio [aHR] 1.19, 95% confidence interval [CI] 0.16, 8.90; p = 0.87 and 0.91, 95% CI 0.39, 2.12; p = 0.83, respectively). However, early mobility groups 4-7 and 1-3 had lower 90-day mortality (aHR 0.47, 95% CI 0.22, 1.01; p = 0.052, and 0.43, 95% CI 0.30, 0.62; p < 0.0001, respectively).

CONCLUSIONS

Only a small proportion of critically ill patients with an expected ICU stay ≥ 72 h were mobilized early. Early mobility was associated with reduced mortality, but not with different incidence of deep-vein thrombosis. This association does not establish causality, and randomized controlled trials are required to assess whether and to what extent this association is modifiable.

TRIAL REGISTRATION

The PREVENT trial is registered at ClinicalTrials.gov, ID: NCT02040103 (registered on 3 November 2013) and Current controlled trials, ID: ISRCTN44653506 (registered on 30 October 2013).

Family coaching during Spontaneous Awakening Trials and Spontaneous Breathing Trials (FamCAB): pilot study protocol

INTRODUCTION

Many patients in the intensive care unit (ICU) require weaning from deep sedation (Spontaneous Awakening Trials, SATs) and mechanical ventilation (Spontaneous Breathing Trials, SBTs) in their journey to recovery. These procedures can be distressing for patients and their families. The presence of family members as 'coaches' during SATs/SBTs could provide patients with reassurance, reduce stress for patients and families and potentially improve procedural success rates.

METHODS AND ANALYSIS

This study will be executed in two phases:Development of a coaching module: a working group including patient partners (i.e., former ICU patients or family members of former ICU patients), researchers, and ICU clinicians will develop an educational module on family coaching during SATs/SBTs (FamCAB). This module will provide families of critically ill patients basic information about SATs/SBTs as well as coaching guidance.Pilot testing: family members of ICU patients will complete the FamCAB module and provide information on: (1) demographics, (2) anxiety and (3) satisfaction with care in the ICU. Family members will then coach the patient through the next clinically indicated SATs and/or SBTs. Information around duration of time and success rates of SATs and/or SBTs (ability to conduct a complete assessment) alongside feedback will be collected. ICU clinical staff (including physicians and nurses) will be asked for feedback on practicality and perceived benefits or drawbacks of family coaching during these procedures. Feasibility and acceptability of family coaching in SATs/SBTs will be determined.

DISCUSSION

The results of this work will inform whether a larger study to explore family coaching during SATs/SBTs is warranted.

ETHICS AND DISSEMINATION

This study has received ethical approval from the University of Calgary Conjoint Health Research Ethics Board. Results from this pilot study will be made available via peer-reviewed journals and presented at critical care conferences on completion.

Care practices for patients requiring mechanical ventilation more than seven days in Swedish intensive care units: A national survey

OBJECTIVE

To identify care practices in Swedish intensive care units specific to patients requiring mechanical ventilation for >7 days.

RESEARCH METHODOLOGY

We conducted a national cross-sectional survey inviting all adult Swedish ICUs (n = 79). Nurse managers were invited by email to complete a questionnaire by telephone. The questionnaire included seven domains: ventilator weaning, mobilisation, communication, nutrition, symptom assessment, psychosocial support and organisational characteristics.

RESULTS

We received responses from 77 units (response rate, 97%). Weaning protocols were available in 42 (55%) units, 52 (68%) used individualised weaning strategies and 50 (65%) involved physicians and nurses in collaborative decision making. In 48 units (62%), early mobilisation was prioritised using bed cycling but only 26 (34%) units had mobilisation protocols. Most of the intensive care units (74, 96%) had nutrition protocols but only 2 (3%) had dedicated dieticians. Delirium screening tools were available in 49 (64%) ICUs, 3 (4%) assessed anxiety and none assessed dyspnoea. Nineteen (25%) units employed a primary nursing model and 11 (14%) indicated person-centred care policies. Regular case conferences, including family participation, were held by 39 (51%) units.

CONCLUSION

We found that an individualised approach to ventilator weaning, decided by physicians and nurses in collaboration, was the predominant approach, although weaning protocols were available in some intensive care units. Most units prioritised early mobilisation, though few used protocols. Nutritional protocols were widely adopted, as few units had a dedicated dietician.

Agitation is a Common Barrier to Recovery of ICU Patients

Importance: Agitation is common in mechanically ventilated ICU patients, but little is known about physician attitudes regarding agitation in this setting. Objectives: To characterize physician attitudes regarding agitation in mechanically ventilated ICU patients. Design, Setting, and Participants: We surveyed critical care physicians within a multicenter health system in Western Pennsylvania, assessing attitudes regarding agitation during mechanical ventilation and use of and confidence in agitation management options. We used quantitative clinical vignettes to determine whether agitation influences confidence regarding readiness for extubation. We sent our survey to 332 critical care physicians, of whom 80 (24%) responded and 69 were eligible (had cared for a mechanically ventilated patient in the preceding three months). Main Outcomes and Measures: Respondent confidence in patient readiness for extubation (0-100%, continuous) and frequency of use and confidence in management options (1-5, Likert). Results: Of 69 eligible responders, 61 (88%) agreed agitation is common and 49 (71%) agreed agitation is a barrier to extubation, but only 27 (39%) agreed their approach to agitation is evidence-based. Attitudes regarding agitation did not differ much by practice setting or physician demographics, though respondents working in medical ICUs were more likely (P = .04) and respondents trained in surgery or emergency medicine were less likely (P = .03) than others to indicate that agitation is an extubation barrier. Fifty-three (77%) respondents reported they frequently use non-pharmacologic measures to treat agitation, and 42 (70%) of those who reported they used non-pharmacologic measures during the prior 3 months indicated confidence in their effectiveness. In responses to clinical vignettes, confidence in patient's readiness for extubation was significantly lower if the patient was agitated (P < .001) or tachypneic (P < .001), but the presence of both agitation and tachypnea did not reduce confidence compared with tachypnea alone (P = .24). Conclusions and Relevance: Most critical care physicians consider agitation during mechanical ventilation a common problem and agreed that agitation is a barrier to extubation. Treatment practice varies widely.

Nurses' knowledge, barriers and practice in the care of patients with delirium in the intensive care unit in Poland-A cross-sectional study

Background

Delirium is a cognitive disorder that occurs with high frequency in patients in intensive care units and affects patient outcomes. Despite recommendations for monitoring and assessing delirium in the ICU, studies show that it is still not routinely assessed and often remains undiagnosed or misinterpreted as dementia or depression.

Aim

The aim of this study was (1) to assess nurses' knowledge and clinical practices regarding delirium, (2) to identify the factors associated with nurses' knowledge, and (3) to define barriers to effective control of delirium.

Methods

A cross-sectional study was conducted among 371 ICU nurses in Poland.

Results

53.1% of nurses had never been educated on delirium control resulting in a deficit in knowledge of delirium symptoms, risk factors and complications associated with delirium in ICU patients. Master's degree in nursing (vs. Registered nurses + Bachelor's), female gender, and working in university hospital (vs. other) were positively correlated with nurse's knowledge, while age had a negative impact on knowledge. Delirium is a marginalized state in ICU patients, only 16.4% of nurses assessed delirium routinely and 35.8% assessed delirium occasionally, rarely using validated scales. Barriers to effective delirium control were primarily the lack of a requirement to assess delirium, the difficulty of assessing delirium in intubated patients and nurses' lack of confidence in their ability to use delirium assessment tools.

Conclusions

There is an urgent need to educate nurses about delirium and to make delirium assessment obligatory in clinical practice. The area of change should also include a hospital policy on delirium monitoring and management. The study was registered on ClinicalTrials.gov (NCT05384964).
