Central venous lines (CVLs) are frequently utilized in critically ill patients and confer a risk of central line-associated bloodstream infections (CLABSIs). CLABSIs are associated with increased mortality, extended hospitalization, and increased costs. Unnecessary CVL utilization contributes to CLABSIs. This initiative sought to implement a clinical decision support system (CDSS) within an electronic health record (EHR) to quantify the prevalence of potentially unnecessary CVLs and improve their timely removal in six adult intensive care units (ICUs).
Methods:
Intervention components included: (1) evaluating existing CDSS’ effectiveness, (2) clinician education, (3) developing/implementing an EHR-based CDSS to identify potentially unnecessary CVLs, (4) audit/feedback, and (5) reviewing EHR/institutional data to compare rates of removal of potentially unnecessary CVLs, device utilization, and CLABSIs pre- and postimplementation. Data was evaluated with statistical process control charts, chi-square analyses, and incidence rate ratios.
Results:
Preimplementation, 25.2% of CVLs were potentially removable, and the mean weekly proportion of these CVLs that were removed within 24 hours was 20.0%. Postimplementation, a greater proportion of potentially unnecessary CVLs were removed (29%, p < 0.0001), CVL utilization decreased, and days between CLABSIs increased. The intervention was most effective in ICUs staffed by pulmonary/critical care physicians, who received monthly audit/feedback, where timely CVL removal increased from a mean of 18.0% to 30.5% (p < 0.0001) and days between CLABSIs increased from 17.3 to 25.7.
Conclusions:
A significant proportion of active CVLs were potentially unnecessary. CDSS implementation, in conjunction with audit and feedback, correlated with a sustained increase in timely CVL removal and an increase in days between CLABSIs.
In anesthesiology and critical care medicine, specific arterial blood pressure targets should be attained, depending on the setting. For instance, a growing body of evidence indicates that perioperative blood pressure should not markedly deviate from its usual level. This underscores the importance of blood pressure measurement, ideally non-invasively, and has therefore spurred intense research efforts . Recent advances in non-invasive blood pressure monitoring are noteworthy. They involve not only innovative technologies such as the automatic finger cuff but also the widely used automatic upper arm cuff. The present chapter aims at providing a state of the art of non-invasive blood pressure monitoring in adult patients in acute care settings with emphasis on recent advances. This chapter addresses several key issues such as “are non-invasive measurements of blood pressure true and accurate?”, “can non-invasive monitoring detect changes in blood pressure? ” and “what if the patient is obese and / or has cardiac arrhythmia?”
Drawing on the research of scholars from both within and outside the field of education, this chapter explores how care ethics can be conceived as permitting and even enabling white saviorism in the teaching context. The author appeals to perspectives offered by the scholarship of decolonial feminists to clarify the morally troubling nature of “care” when a teacher’s care contributes to devalorizing the cultural wealth, history, knowledge systems, and ways of being of minoritized and marginalized students. However, convinced that care ethics still confers invaluable moral worth on the teaching practice, the author highlights the effort of scholars from the traditions of critical race theory in prescribing “critical care” as a teaching praxis.
This umbrella review will summarize palliative and end-of-life care practices in peri-intensive care settings by reviewing systematic reviews in intensive care unit (ICU) settings. Evidence suggests that integrating palliative care into ICU management, initiating conversations about care goals, and providing psychological and emotional support can significantly enhance patient and family outcomes.
Methods
The Joanna Briggs Institute (JBI) methodology for umbrella reviews will be followed. The search will be carried out from inception until 30 September 2023 in the following databases: Cochrane Library, SCOPUS, Web of Science, CINAHL Complete, Medline, EMBASE, and PsycINFO. Two reviewers will independently conduct screening, data extraction, and quality assessment, and to resolve conflicts, adding a third reviewer will facilitate the consensus-building process. The quality assessment will be carried out using the JBI Critical Appraisal Checklist. The review findings will be reported per the guidelines outlined in the Preferred Reporting Items for Overviews of Reviews statement.
Results
This umbrella review seeks to inform future research and practice in critical care medicine, helping to ensure that end-of-life care interventions are optimized to meet the needs of critically ill patients and their families.
Sepsis is currently defined as life-threatening organ dysfunction caused by dysregulated host response to infection. Septic shock is sepsis with persistent hypotension requiring vasopressor to maintain mean arterial pressure (MAP) ≥ 65 mmHg and having a serum lactate > 2 mmol/dL despite adequate fluid resuscitation.
There is wide variation in test characteristics for screening scores such as systemic inflammatory response syndrome (SIRS), quick Sequential Organ Failure Assessment (qSOFA), National Early Warning Score (NEWS) and Modified Early Warning Score (MEWS). A qSOFA score of ≥ 2 or a change in SOFA score of ≥ 2 can promptly identify these patients; however, qSOFA is not recommended as a single screening tool over comparable scores such as SIRS, NEWS, or MEWS.
Neurodevelopmental challenges are the most prevalent comorbidity associated with a diagnosis of critical CHD, and there is a high incidence of gross and fine motor delays noted in early infancy. The frequency of motor delays in hospitalised infants with critical CHD requires close monitoring from developmental therapies (physical therapists, occupational therapists, and speech-language pathologists) to optimise motor development. Currently, minimal literature defines developmental therapists’ role in caring for infants with critical CHD in intensive or acute care hospital units.
Purpose:
This article describes typical infant motor skill development, how the hospital environment and events surrounding early cardiac surgical interventions impact those skills, and how developmental therapists support motor skill acquisition in infants with critical CHD. Recommendations for healthcare professionals and those who provide medical or developmental support in promotion of optimal motor skill development in hospitalised infants with critical CHD are discussed.
Conclusions:
Infants with critical CHD requiring neonatal surgical intervention experience interrupted motor skill interactions and developmental trajectories. As part of the interdisciplinary team working in intensive and acute care settings, developmental therapists assess, guide motor intervention, promote optimal motor skill acquisition, and support the infant’s overall development.
This case study recounts an application of Ehlers and Clark’s (2000) cognitive model of post-traumatic stress disorder (PTSD) to post-intensive care unit (post-ICU) PTSD. An AB single case design was implemented. The referred patient, Rosalind (pseudonym), completed several psychometric measures prior to the commencement of therapy (establishing a baseline), as well as during and at the end of therapy. Idiosyncratic measures were also implemented to capture changes during specific phases of treatment. The importance of the therapeutic alliance, particularly in engendering a sense of safety, was highlighted. Findings support the use of cognitive therapy for PTSD (CT-PTSD) with an older adult, in the context of a coronavirus infectious disease (COVID-19)-related ICU admission. This case is also illustrative of the effectiveness of implementing CT-PTSD in the context of co–morbid difficulties and diagnoses of delirium, depression, and complicated grief.
Key learning aims
(1) To recognise the therapeutic value of CT-PTSD in addressing PTSD following a COVID-19 admission, in the context of complicated grief and delirium.
(2) To consider the importance of a strong therapeutic alliance when undertaking CT–PTSD.
(3) To understand the intersection of complicated grief and delirium in the context of ICU trauma.
(4) To consider the challenges in working with PTSD, whereby the target trauma (COVID–19 ICU admission) is linked with ongoing uncertainty and continuing indeterminate threat.
Objective, evidence-based neuroprognostication of postarrest patients is crucial to avoid inappropriate withdrawal of life-sustaining therapies or prolonged, invasive, and costly therapies that could perpetuate suffering when there is no chance of an acceptable recovery. Postarrest prognostication guidelines exist; however, guideline adherence and practice variability are unknown.
Objective:
To investigate Canadian practices and opinions regarding assessment of neurological prognosis in postarrest patients.
Methods:
An anonymous electronic survey was distributed to physicians who care for adult postarrest patients.
Results:
Of the 134 physicians who responded to the survey, 63% had no institutional protocols for neuroprognostication. While the use of targeted temperature management did not affect the timing of neuroprognostication, an increasing number of clinical findings suggestive of a poor prognosis affected the timing of when physicians were comfortable concluding patients had a poor prognosis. Variability existed in what factors clinicians’ thought were confounders. Physicians identified bilaterally absent pupillary light reflexes (85%), bilaterally absent corneal reflexes (80%), and status myoclonus (75%) as useful in determining poor prognosis. Computed tomography, magnetic resonance imaging, and spot electroencephalography were the most useful and accessible tests. Somatosensory evoked potentials were useful, but logistically challenging. Serum biomarkers were unavailable at most centers. Most (79%) physicians agreed ≥2 definitive findings on neurologic exam, electrophysiologic tests, neuroimaging, and/or biomarkers are required to determine a poor prognosis with a high degree of certainty. Distress during the process of neuroprognostication was reported by 70% of physicians and 51% request a second opinion from an external expert.
Conclusion:
Significant variability exists in post-cardiac arrest neuroprognostication practices among Canadian physicians.
Pediatric health-care workers often care for families of minority religious backgrounds, but little is known about their perspective in providing culturally and spiritually appropriate care for Muslim patients. We aimed to (1) characterize the attitudes, knowledge, and skills of health-care workers in the care of critically ill Muslim children and (2) evaluate preferences for different educational interventions to improve care of critically ill Muslim children.
Methods
We administered a single-center, cross-sectional, 33-question, electronic survey of interdisciplinary health-care workers in a large pediatric intensive care unit in New York City to characterize their attitudes, knowledge, and skills in caring for critically ill Muslim children.
Results
Of 413 health-care workers surveyed, there were 109 (26%) respondents. Participants responded correctly to 51.7 ± 22.2% (mean ± SD) and 69.2 ± 20.6% of background knowledge and clinical skills questions, respectively. Only 29.8% of participants perceived adequate institutional resources to provide culturally competent care to Muslim patients and their families. Participants identified end-of-life care (47.5%) and bioethical concerns (45%) as needed areas for additional institutional resources. When asked about support to aid in caring for Muslim patients, 43.4% of participants requested a team of Muslim health-care workers to provide guidance. Participants most often requested video-based training modules (32.5%) and written materials (30%) as potential educational interventions.
Significance of results
We identify gaps in health-care worker knowledge and skills in the care of the critically ill Muslim child. We also describe possible areas for intervention to facilitate culturally and spiritually appropriate care delivery to Muslim children and families.
The National Pediatric Cardiology Quality Improvement Collaborative (NPC-QIC) lacks a rigorous enrollment audit process, unlike other collaborative networks. Most centers require individual families to consent to participate. It is unknown whether there is variation across centers or biases in enrollment.
Methods:
We used the Pediatric Cardiac Critical Care Consortium (PC4) registry to assess enrollment rates in NPC-QIC for those centers participating in both registries using indirect identifiers (date of birth, date of admission, gender, and center) to match patient records. All infants born 1/1/2018–12/31/2020 and admitted 30 days of life were eligible. In PC4, all infants with a fundamental diagnosis of hypoplastic left heart or variant or who underwent a surgical or hybrid Norwood or variant were eligible. Standard descriptive statistics were used to describe the cohort and center match rates were plotted on a funnel chart.
Results:
Of 898 eligible NPC-QIC patients, 841 were linked to 1,114 eligible PC4 patients (match rate 75.5%) in 32 centers. Match rates were lower in patients of Hispanic/Latino ethnicity (66.1%, p = 0.005), and those with any specified chromosomal abnormality (57.4%, p = 0.002), noncardiac abnormality (67.8%, p = 0.005), or any specified syndrome (66.5%, p = 0.001). Match rates were lower for patients who transferred to another hospital or died prior to discharge. Match rates varied from 0 to 100% across centers.
Conclusions:
It is feasible to match patients between the NPC-QIC and PC4 registries. Variation in match rates suggests opportunities for improvement in NPC-QIC patient enrollment.
The 2019 coronavirus disease (COVID-19) pandemic created overwhelming demand for critical care services within Maryland’s (USA) hospital systems. As intensive care units (ICUs) became full, critically ill patients were boarded in hospital emergency departments (EDs), a practice associated with increased mortality and costs. Allocation of critical care resources during the pandemic requires thoughtful and proactive management strategies. While various methodologies exist for addressing the issue of ED overcrowding, few systems have implemented a state-wide response using a public safety-based platform. The objective of this report is to describe the implementation of a state-wide Emergency Medical Services (EMS)-based coordination center designed to ensure timely and equitable access to critical care.
Methods:
The state of Maryland designed and implemented a novel, state-wide Critical Care Coordination Center (C4) staffed with intensivist physicians and paramedics purposed to ensure appropriate critical care resource management and patient transfer assistance. A narrative description of the C4 is provided. A retrospective cohort study design was used to present requests to the C4 as a case series report to describe the results of implementation.
Results:
Providing a centralized asset with regional situational awareness of hospital capability and bed status played an integral role for directing the triage process of critically ill patients to appropriate facilities during and after the COVID-19 pandemic. A total of 2,790 requests were received by the C4. The pairing of a paramedic with an intensivist physician resulted in the successful transfer of 67.4% of requests, while 27.8% were managed in place with medical direction. Overall, COVID-19 patients comprised 29.5% of the cohort. Data suggested increased C4 usage was predictive of state-wide ICU surges. The C4 usage volume resulted in the expansion to pediatric services to serve a broader age range. The C4 concept, which leverages the complimentary skills of EMS clinicians and intensivist physicians, is presented as a proposed public safety-based model for other regions to consider world-wide.
Conclusion:
The C4 has played an integral role in the State of Maryland’s pledge to its citizens to deliver the right care to the right patient at the right time and can be considered as a model for adoption by other regions world-wide.
Little is known about strategies to implement new critical care practices in response to COVID-19. Moreover, the association between differing implementation climates and COVID-19 clinical outcomes has not been examined. The purpose of this study was to evaluate the relationship between implementation determinants and COVID-19 mortality rates.
Methods:
We used mixed methods guided by the Consolidated Framework for Implementation Research (CFIR). Semi-structured qualitative interviews were conducted with critical care leaders and analyzed to rate the influence of CFIR constructs on the implementation of new care practices. Qualitative and quantitative comparisons of CFIR construct ratings were performed between hospital groups with low- versus high-mortality rates.
Results:
We found associations between various implementation factors and clinical outcomes of critically ill COVID-19 patients. Three CFIR constructs (implementation climate, leadership engagement, and engaging staff) had both qualitative and statistically significant quantitative correlations with mortality outcomes. An implementation climate governed by a trial-and-error approach was correlated with high COVID-19 mortality, while leadership engagement and engaging staff were correlated with low mortality. Another three constructs (needs of patient; organizational incentives and rewards; and engaging implementation leaders) were qualitatively different across mortality outcome groups, but these differences were not statistically significant.
Conclusions:
Improving clinical outcomes during future public health emergencies will require reducing identified barriers associated with high mortality and harnessing salient facilitators associated with low mortality. Our findings suggest that collaborative and engaged leadership styles that promote the integration of new yet evidence-based critical care practices best support COVID-19 patients and contribute to lower mortality.
The aim of this article is to review and synthesize the evidence on end-of-life in burn intensive care units.
Methods
Systematic scoping review: Preferred Reporting Items for Systemic Reviews extension for Scoping Reviews was used as a reporting guideline. Searches were performed in 3 databases, with no time restriction and up to September 2021.
Results
A total of 16,287 documents were identified; 18 were selected for analysis and synthesis. Three key themes emerged: (i) characteristics of the end-of-life in burn intensive care units, including end-of-life decisions, decision-making processes, causes, and trajectories of death; (ii) symptom control at the end-of-life in burn intensive care units focusing on patients’ comfort; and (iii) concepts, models, and designs of the care provided to burned patients at the end-of-life, mainly care approaches, provision of care, and palliative care.
Significance of results
End-of-life care is a major step in the care provided to critically ill burned patients. Dying and death in burn intensive care units are often preceded by end-of-life decisions, namely forgoing treatment and do-not-attempt to resuscitate. Different dying trajectories were described, suggesting the possibility to develop further studies to identify triggers for palliative care referral. Symptom control was not described in detail. Palliative care was rarely involved in end-of-life care for these patients. This review highlights the need for early and high-quality palliative and end-of-life care in the trajectories of critically ill burned patients, leading to an improved perception of end-of-life in burn intensive care units. Further research is needed to study the best way to provide optimal end-of-life care and foster integrated palliative care in burn intensive care units.
Coronavirus disease 2019 increased the numbers of patients requiring prolonged mechanical ventilation, with a subsequent increase in tracheostomy procedures. Coronavirus disease 2019 patients are high risk for surgical complications. This review examines open surgical and percutaneous tracheostomy complications in coronavirus disease 2019 patients.
Methods
Medline and Embase databases were searched (November 2021), and the abstracts of relevant articles were screened. Data were collected regarding tracheostomy technique and complications. Complication rates were compared between percutaneous and open surgical tracheostomy.
Results
Percutaneous tracheostomy was higher risk for bleeding, pneumothorax and false passage. Surgical tracheostomy was higher risk for peri-operative hypoxia. The most common complication for both techniques was post-operative bleeding.
Conclusion
Coronavirus disease 2019 patients undergoing tracheostomy are at higher risk of bleeding and peri-operative hypoxia than non-coronavirus disease patients. High doses of anti-coagulants may partially explain this. Reasons for higher bleeding risk in percutaneous over open surgical technique remain unclear. Further research is required to determine the causes of differences found and to establish mitigating strategies.
Continuous EEG (cEEG) monitoring offers bedside, noninvasive, diffuse, and continuous information about brain function. These characteristics allow clinicians to assess brain function, evaluate for changes in brain function over time, and identify electrographic seizures that are often not clinically observable. These advantages have led to widespread and increasing use of cEEG in critically ill patients across the age spectrum. This chapter introduces cEEG in critically ill neonates and children including seizure epidemiology (incidence and risk factors), the relationship between electrographic seizures and outcome, available consensus statements and guidelines, and role of quantitative EEG.
The use of electrophysiological methods to monitor patients for cerebral ischemia is based on the observation that electrical brain activity is exquisitely dependent on adequate cerebral perfusion. The effect of ischemia on the EEG is dependent on the degree, duration, and rate of hypoperfusion, as well as on the cerebral metabolic rate, which itself can be influenced by sedation and body temperature. EEG can serve as an early indicator of ischemia, before clinical signs may be apparent and potentially before permanent injury occurs. Visual interpretation can be assisted by quantitative EEG analysis (QEEG). This chapter details the use of neuromonitoring for the detection of ischemia.
Demand for neuromonitoring in neonatal, pediatric and cardiac intensive care units continues to grow, motivated by increased awareness of the high prevalence of seizures among critically ill neonates and children, and emerging evidence that these seizures can contribute to brain injury. This book provides physicians, nurses and trainees caring for critically ill newborns and children with a practical overview of how to use and interpret continuous neuromonitoring to enhance patient care. Authored by international experts from diverse institutions and professional backgrounds, this is a practical guide that is accessible to intensive care specialists, but also comprehensive enough to serve as a reference book for neurologists and neurophysiologists. Concise enough to be read cover-to-cover and illustrated with over thirty case-based examples, this authoritative reference will guide readers in accurate neuromonitoring interpretation and optimal use of conventional EEG, amplitude-integrated EEG and other quantitative EEG techniques.
The surge in critically ill patients has pressured hospitals to expand their intensive care unit capacities and critical care staff. This was difficult given the country’s shortage of intensivists. This paper describes the implementation of a multidisciplinary central line placement team and its impact in reducing the vascular access workload of ICU physicians during the height of the COVID-19 pandemic.
Methods:
Vascular surgeons, interventionalists, and anesthesiologists, were redeployed to the ICU Access team to place central and arterial lines. Nurses with expertise in vascular access were recruited to the team to streamline consultation and assist with line placement.
Results:
While 51 central and arterial lines were placed per 100 ICU patients in 2019, there were 87 central and arterial lines placed per 100 COVID-19 ICU patients in the sole month of April, 2020. The ICU Access Team placed 107 of the 226 vascular access devices in April 2020, reducing the procedure-related workload of ICU treating teams by 46%.
Conclusions:
The ICU Access Team was able to complete a large proportion of vascular access insertions without reported complications. Given another mass casualty event, this ICU Access Team could be reassembled to rapidly meet the increased vascular access needs of patients.
Nutritional therapy should follow evidence-based practice, thus several societies regarding nutrition and critical care have developed specific Clinical Practice Guidelines (CPG). However, to be regarded as trustworthy, the quality of the CPG for critically ill patients and its recommendations need to be high. This systematic review aimed to appraise the methodology and recommendations of nutrition CPG for critically ill patients. We performed a systematic review (protocol number CRD42020184199) with literature search conducted on PubMed, Embase, Cochrane Library and other four specific databases of guidelines up to October 2021. Two reviewers, independently, assessed titles and abstracts and potentially eligible full-text reports to determine eligibility and subsequently four reviewers appraised the guidelines quality using the Advancing Guideline Development, Reporting and Evaluation in Health Care instrument II (AGREE-II) and AGREE-Recommendation Excellence (AGREE-REX). Ten CPG for nutrition in critically ill patients were identified. Only Academy of Nutrition and Dietetics and European Society of Intensive Care Medicine had a total acceptable quality and were recommended for daily practice according AGREE-II. None of the CPG recommendations had an overall quality score above 70 %, thus being classified as moderate quality according AGREE-REX. The methodological evaluation of the critically ill adult patient CPG revealed significant discrepancies and showed a need for improvement in its development and/or reporting. In addition, recommendations about nutrition care process presented a moderate quality.
