Surgical critical care: Is work–life expectancy increasing? An analysis of American Board of Surgery recertification rates across subspecialties

The practice of surgical critical care (SCC) has traditionally necessitated additional in-house, extended night and weekend clinical commitments, which can be viewed as less desirable for many surgeons. Therefore, the...

Toward Equitable Kidney Function Estimation in Critical Care Practice: Guidance From the Society of Critical Care Medicine's Diversity, Equity, and Inclusion in Renal Clinical Practice Task Force.

Accurate glomerular filtration rate (GFR) assessment is essential in critically ill patients. GFR is often estimated using creatinine-based equations, which require surrogates for muscle mass such as age and sex. Race has also been included in GFR equations, based on the assumption that Black individuals have genetically determined higher muscle mass. However, race-based GFR estimation has been questioned with the recognition that race is a poor surrogate for genetic ancestry, and racial health disparities are driven largely by socioeconomic factors. The American Society of Nephrology and the National Kidney Foundation (ASN/NKF) recommend widespread adoption of new "race-free" creatinine equations, and increased use of cystatin C as a race-agnostic GFR biomarker. Literature review and expert consensus. English language publications evaluating GFR assessment and racial disparities. We provide an overview of the ASN/NKF recommendations. We then apply an Implementation science methodology to identify facilitators and barriers to implementation of the ASN/NKF recommendations into critical care settings and identify evidence-based implementation strategies. Last, we highlight research priorities for advancing GFR estimation in critically ill patients. Implementation of the new creatinine-based GFR equation is facilitated by low cost and relative ease of incorporation into electronic health records. The key barrier to implementation is a lack of direct evidence in critically ill patients. Additional barriers to implementing cystatin C-based GFR estimation include higher cost and lack of test availability in most laboratories. Further, cystatin C concentrations are influenced by inflammation, which complicates interpretation. The lack of direct evidence in critically ill patients is a key barrier to broad implementation of newly developed "race-free" GFR equations. Additional research evaluating GFR equations in critically ill patients and novel approaches to dynamic kidney function estimation is required to advance equitable GFR assessment in this vulnerable population.

Experiences, barriers and expectations regarding current patient monitoring systems among ICU nurses in a University Hospital in Lebanon: a qualitative study.

The aim of the study is to assess the experiences, barriers, and expectations regarding current patient monitoring systems among intensive care unit nurses at one university hospital. A qualitative exploratory study approach was adopted to test the research questions. Intensive care unit personnel placed a high value on practical criteria such as user friendliness and visualization while assessing the present monitoring system. Poor alarm handling was recognized as possible patient safety hazards. The necessity of high accessibility was highlighted once again for a prospective system; wireless, noninvasive, and interoperability of monitoring devices were requested; and smart phones for distant patient monitoring and alert management improvement were required. Core comments from ICU personnel are included in this qualitative research on patient monitoring. All national healthcare involved parties must focus more on user-derived insights to ensure a speedy and effective introduction of digital health technologies in the ICU. The findings from the alarm control or mobile device studies might be utilized to train ICU personnel to use new technology, minimize alarm fatigue, increase medical device accessibility, and develop interoperability standards in critical care practice.

Effect of Virtual Education on Knowledge and Practice of Critical Care Nurses Regarding the Administration of Drugs Through Enteral Feeding Tubes: A Prospective Randomized Pre-Post Intervention Study.

A study was conducted to evaluate the effect of virtual education on knowledge and practice of nurses regarding administration of drugs through enteral feeding tubes (EFTs). Sixty nurses working in 4 intensive care units were enrolled. A questionnaire evaluating knowledge and practice of nurses regarding drug administration through EFTs was used. At the pre-intervention stage, all nurses responded to the questionnaire. Then an educational videoclip was provided to the intervention group. One month later, post-intervention stage, both groups answered to the questionnaire again. At the end of the study, the scores of all items in the knowledge domain including medication preparation (mean difference [MD] [95% CI]: 1.11 [0.57; 1.66]), tube flushing (MD [95% CI]: 2.15 [1.59; 2.79]), recognizing drug-drug/drug-feed interactions (MD [95% CI]: 0.57 [0.05; 1.09]), and recognizing dosage forms (MD [95% CI]: 1.51 [0.94; 2.10]) and practice domain including medication preparation (MD [95% CI]: 1.63 [1.04; 2.21]), tube flushing (MD [95% CI]: 1.19 [0.64; 1.74]), and recognizing drug-drug/drug-feed interactions [MD (95% CI): 2.16 (1.53; 2.80)] in the intervention group were significantly higher than those in the control group (P <.05). Education of proper technics of preparation and administration of drugs through EFTs improved knowledge and practice of the participants.

Gamification in Critical Care Education and Practice.

To explore gamification as an alternative approach to healthcare education and its potential applications to critical care. English language manuscripts addressing: 1) gamification theory and application in healthcare and critical care and 2) implementation science focused on the knowledge-to-practice gap were identified in Medline and PubMed databases (inception to 2023). Studies delineating gamification underpinnings, application in education or procedural mentoring, utilization for healthcare or critical care education and practice, and analyses of benefits or pitfalls in comparison to other educational or behavioral modification approaches. Data indicated the key gamification tenets and the venues within which they were used to enhance knowledge, support continuing medical education, teach procedural skills, enhance decision-making, or modify behavior. Gamification engages learners in a visual and cognitive fashion using competitive approaches to enhance acquiring new knowledge or skills. While gamification may be used in a variety of settings, specific design elements may relate to the learning environment or learner styles. Additionally, solo and group gamification approaches demonstrate success and leverage adult learning theory elements in a low-stress and low-risk setting. The potential for gamification-driven behavioral modification to close the knowledge-to-practice gap and enable guideline and protocol compliance remains underutilized. Gamification offers the potential to substantially enhance how critical care professionals acquire and then implement new knowledge in a fashion that is more engaging and rewarding than traditional approaches. Accordingly, educational undertakings from courses to offerings at medical professional meetings may benefit from being gamified.

A prospective observational study of sepsis-associated coagulopathy (SAC) in septic shock in the pediatric intensive care unit of tertiary care hospital in central rural India

Background: Sepsis-associated coagulopathy (SAC) is a frequently encountered clinical scenario in pediatric critical care practice. The disruptions within the normal coagulation cascade in cases of sepsis significantly impact the ultimate patient outcome. Objective: This study aims to evaluate the associations between sepsis-associated coagulopathy (SAC) in pediatric septic shock cases and their corresponding clinical outcomes. Methods: This study will be conducted within a tertiary care Pediatric Intensive Care Unit (PICU), focusing on children aged one month to 18 years who have been admitted to manage sepsis. Cases diagnosed with sepsis will undergo evaluation and treatment according to the established PICU protocol. Coagulation profiles, encompassing International Normalized Ratio (INR), activated Partial Thromboplastin Time (aPTT), Prothrombin Time (PT), and platelet counts, will be subjected to analysis. Any deviations in coagulation parameters will be compared and correlated with morbidity and mortality outcomes. Expected results: This study will establish correlations between the severity of sepsis and its subsequent outcomes, specifically concerning aberrations in coagulation profile levels. A meticulous analysis will focus on critically ill cases necessitating various interventions and exhibiting deviant coagulation patterns. Conclusions: This research aims to unravel potentially pivotal prognostic correlations within sepsis cases. The coagulation profile, a standard investigation, can be a predictive tool for outcomes within the Pediatric Intensive Care Unit (PICU).

P09 Lancashire and South Cumbria Critical Care Network Vancomycin Project

Abstract Background This project was a collaborative piece of work across a critical care network that included specialist advice from colleagues including aseptic/technically trained pharmacists and microbiology to optimize care for critical care patients in Lancashire and South Cumbria. We used several members of our workforce including pharmacists, nursing staff, microbiologists, rotational doctors and consultants to work towards a harmonized guideline. Methods During our initial meeting, we identified that different centres were using different glycopeptides and administering them differently: East Lancashire Hospitals (ELHT)—continuous vancomycin infusion; Blackpool Cardiac and Blackpool General—continuous vancomycin infusion, with no formal guideline in place but adopted from ELHT; Lancashire Teaching Hospitals—intermittent vancomycin infusions; and University Hospitals Morecambe Bay—teicoplanin is glycopeptide of choice. Our consultant microbiologist discussed the use of glycopeptides and what infections they are used for in critical care. The pharmacokinetics of vancomycin and the benefit of using a continuous infusion was also discussed. We decided to undertake a clinical audit of our vancomycin guidelines at ELHT to ensure that we had an evidence base to implement our guideline and provide assurance to the working group. We agreed to reconvene the working group after this audit was completed and after the concerns of colleagues had been addressed. Results and conclusions We presented the results of our audit and highlighted the opportunities harmonizing this guideline would provide. We discussed various scenarios such as stepping up from a ward protocol to a continuous infusion and the different methods of calculating creatinine clearance and if this would influence the first 24 h of the infusion. One comment was concerning the administration of vancomycin and the number of times nurses will be changing bags for patients requiring higher doses, i.e. the majority of patients would usually be on 3 g/day or more depending on concentrations. This would mean changing the bag more than twice a day; as much as there is a therapeutic benefit to continuous vancomycin infusions, considering the max. concentration for peripheral and central lines allows for larger volumes, it would be beneficial (except in fluid restricted cases) to have a slightly larger volume to reduce the number of bag changes and plastic consumption. We considered this comment and discussed it with our aseptic services lead pharmacist. We attended a meeting of the ICS Aseptics Working Party across Lancashire and South Cumbria. WE discussed the proposed guideline and requested that aseptic units across Lancashire and South Cumbria developed worksheets to manufacture 5 g in 600 mL or 10 g in 1.2 L for central use to stop breaking the line when changing a bag and reducing plastic consumption. We also met with critical care practice educators across the network to discuss how we can promote this guideline and ensure nursing staff and prescribers are aware of how to prescribe and administer continuous vancomycin infusions. One of our units noted that they have had a few incidents with incorrect concentrations of vancomycin being made up for patients. We developed an e-learning package to educate our workforce.

Critical Advances for Democratizing Ultrasound Diagnostics in Human and Veterinary Medicine.

The democratization of ultrasound imaging refers to the process of making ultrasound technology more accessible. Traditionally, ultrasound imaging has been predominately used in specialized medical facilities by trained professionals. Advancements in technology and changes in the health-care landscape have inspired efforts to broaden the availability of ultrasound imaging to various settings such as remote and resource-limited areas. In this review, we highlight several key factors that have contributed to the ongoing democratization of ultrasound imaging, including portable and handheld devices, recent advancements in technology, and training and education. Examples of diagnostic point-of-care ultrasound (POCUS) imaging used in emergency and critical care, gastroenterology, musculoskeletal applications, and other practices are provided for both human and veterinary medicine. Open challenges and the future of POCUS imaging are presented, including the emerging role of artificial intelligence in technology development.

A rapid scoping review of barriers and facilitators of implementing delirium prevention practices in adult critical care

Background: Delirium is a serious complication of critical care that can have lasting effects on the patient’s life. Much of the work to date about delirium has been focused on identifying delirium risk factors, developing tools for screening and recognizing delirium, and testing interventions to treat those diagnosed with delirium. Despite evidence, implementing known delirium prevention and management strategies remains abysmal. This review aimed to identify and summarize literature reporting on the barriers and facilitators of implementing delirium prevention and management practices in adult critical care. Methods: A rapid scoping review of the literature was conducted. The databases CINAHL and Ovid Medline were searched, and forward and backward reference checking was completed. Data abstraction and analysis were performed by one reviewer and verified by a second reviewer. Results: After review of 74 full-text papers, 32 articles were included in the review. The articles were published between 2008 and 2022, with the majority conducted in the United States (53%). The barriers and facilitators of delirium prevention and management practices described in the reviewed articles were categorized as patient-level, clinician-level, and organizational-level factors. Conclusion: The review found consistency among the published results. However, opportunities to continue to grow research in this area remain; specifically in examining the opportunity to understand better the decision-making process surrounding how care is prioritized when taking into consideration the present barriers and facilitators and the opportunity to use implementation science to create and sustain change in the practice of delirium prevention and management strategies.

Communication in the ICU: An Unintended Nocebo Effect?

To identify medical phrases utilized by the critical care team that may have an unintended impact on the critically ill patient, we administered an anonymous survey to multi-professional critical care team members. We elicited examples of imprecise language that may have a negative emotional impact on the critically ill. Of the 1600 providers surveyed, 265 offered 1379 examples (912 unique) which were clustered into 5 categories. Medical jargon (eg, "riding the vent") was most prevalent (n = 549). There were 217 negative suggestions (eg, "you will feel a stick and a burn"). Hyperboles (eg, "black cloud") were common (n = 198) while homonyms (ie "he fibbed") accounted for 150 examples. Phrases such as "code brown in there" were categorized as metonyms (n = 144). 121 metaphors/similes (eg, "rearranging deck chairs on the Titanic") were provided. Phrases that have the potential to negatively impact critically ill patient perceptions are commonplace in critical care practice. Whether these everyday communication habits lead to an unintended nocebo effect on mental health outcomes of the critically ill deserves further study.

Ultrasonography in the intensive care unit: a bibliometrics analysis.

Ultrasonography is widely used in critical care practice. The status of related studies remains unclear. The purpose of this study is to analyze current literature investigating the use of ultrasound in critical care units by using bibliometric analysis. The Science Citation Index Expanded (SCI-E) database was used for data retrieval. The search formula for literature retrieval was "ultrasound" OR "ultrasonography" AND "intensive care unit" OR "critical care unit" OR "intensive care" OR "critical care". The bibliometric software package of R software was used to analyze the results. Information of related literatures were analyzed. Finally, 3,715 articles were included. The number of published articles and the number of references increased annually. The research fields included medical imaging, critical care medicine, cardiology, etc. The United States has published more documents in this field than other countries and has shown the highest rate of cooperation with other countries. Among the top 10 research institutions with the largest number of publications, 5 are from France and 3 are from the United States. There are many authors from China in the top 10 published studies. Among the top 10 journals with the largest number of published articles, 5 journals are top journals in the field of critical care medicine. Among the top 10 keywords, there are 5 of ultrasound specialty and 2 of critical care medicine. Researches on the use of ultrasound in critical care units are mainly concentrated in several developed countries in Europe and the United States. Chinese research institutions should perform more studies in this field and increase cooperation with institutions from other countries.

Chest X-rays and Lung Ultrasound Are Not Interchangeable in Intensive Care Practice.

Data comparing lung ultrasound (LUS) and chest X-rays (CXRs) have increased over the past years. However, there still is a lack of knowledge as to how these modalities compare with one another in the critical care setting, and several factors, including artificial study conditions, limit the generalizability of most published studies. Our study aimed to analyze the performance of LUS in comparison with CXRs in real-world critical care practice. This study presents new data from the prospective FASP-ICU trial. A total of 209 corresponding datasets of LUS and CXR results from 111 consecutive surgical ICU patients were subanalyzed, and categorial findings were compared. Statistical analysis was performed on the rates of agreement between the different imaging modalities. A total of 1162 lung abnormalities were detected by LUS in ICU patients compared with 1228 detected by CXR, a non-significant difference (p = 0.276; 95% CI -0.886 to 0.254). However, the agreement rates varied between the observed abnormalities: the rate of agreement for the presence of interstitial syndrome ranged from 0 to 15%, consolidation from 0 to 56%, basal atelectasis from 33.9 to 49.34%, pleural effusion from 40.65 to 50%, and compression atelectasis from 14.29 to 19.3%. The rate of agreement was 0% for pneumothorax and 20.95% for hypervolemia. LUS does not detect more lung abnormalities in real-world critical care practice than CXRs, although a higher sensitivity of LUS has been reported in previous studies. Overall, low agreement rates between LUS and CXRs suggest that these diagnostic techniques are not equivalent but instead are complementary and should be used alongside each other.

Critical care delivery across health care systems in low-income and low-middle-income country settings: A systematic review.

Prior research has demonstrated that low- and low-middle-income countries (LLMICs) bear a higher burden of critical illness and have a higher rate of mortality from critical illness than high-income countries (HICs). There is a pressing need for improved critical care delivery in LLMICs to reduce this inequity. This systematic review aimed to characterise the range of critical care interventions and services delivered within LLMIC health care systems as reported in the literature. A search strategy using terms related to critical care in LLMICs was implemented in multiple databases. We included English language articles with human subjects describing at least one critical care intervention or service in an LLMIC setting published between 1 January 2008 and 1 January 2020. A total of 1620 studies met the inclusion criteria. Among the included studies, 45% of studies reported on pediatric patients, 43% on adults, 23% on infants, 8.9% on geriatric patients and 4.2% on maternal patients. Most of the care described (94%) was delivered in-hospital, with the remainder (6.2%) taking place in out-of-hospital care settings. Overall, 49% of critical care described was delivered outside of a designated intensive care unit. Specialist physicians delivered critical care in 60% of the included studies. Additional critical care was delivered by general physicians (40%), as well as specialist physician trainees (22%), pharmacists (16%), advanced nursing or midlevel practitioners (8.9%), ambulance providers (3.3%) and respiratory therapists (3.1%). This review represents a comprehensive synthesis of critical care delivery in LLMIC settings. Approximately 50% of critical care interventions and services were delivered outside of a designated intensive care unit. Specialist physicians were the most common health care professionals involved in care delivery in the included studies, however generalist physicians were commonly reported to provide critical care interventions and services. This study additionally characterised the quality of the published evidence guiding critical care practice in LLMICs, demonstrating a paucity of interventional and cost-effectiveness studies. Future research is needed to understand better how to optimise critical care interventions, services, care delivery and costs in these settings. PROSPERO CRD42019146802.

Evaluating the Health of the Work Environment and the Perception of New Nurses During the Transition to Practice in Critical Care.

New nurses are the major source of hiring for most hospitals. They fill vacancies left by seasoned nurses creating an experience-complexity gap. Turnover among new-graduate nurses is as high as 85% in the first 2 years. The purpose of this study was to provide a deeper understanding of the factors contributing to turnover. The specific aims were (1) to better understand novice nurses' perceptions of their transition to critical-care practice and (2) to describe all eligible critical-care nurses' perceptions of a healthy work environment. A quantitative descriptive design was used. Data were collected over 3 weeks in February 2022 from novice nurses (n = 12) who completed the Casey-Fink Nurse Experience Survey and from novice and experienced nurses (n = 47) who completed the American Association of Critical-Care Nurses' Healthy Work Environment Assessment Tool. Data were analyzed using descriptive statistics. Respondents to the Casey-Fink Nurse Experience Survey (n = 12) indicated feeling well supported by family, friends, and preceptors, although they felt less positive about prioritizing care, organizing patient needs, and recommending changes to the plan of care. The overall mean score on the Health Work Environment Assessment Tool was 2.99 (n = 47), indicating the need for improvement. Responses varied by unit, years of experience, and certification status. This study contributes to the evolving body of nursing knowledge and has provided a more detailed understanding of the health of the work environment and perceptions of new nurses during the transition to practice.

This AOTA Position Statement defines the distinct role and value of occupational therapy practitioners in critical care settings across the lifespan. Occupational therapy practitioners are essential interprofessional team members who address the needs of critically ill individuals by implementing evidence-based critical care guidelines that aim to improve the quality of survivorship.

Understanding and Managing Anxiety Sensitivity During Critical Illness and Long-Term Recovery.

Anxiety sensitivity is a fear of symptoms associated with anxiety (eg, rapid respiration and heart rate, perspiration), also known as "fear of fear." This fear is a misinterpretation of nonthreatening symptoms as threatening across 3 domains: physical ("When my heart rate increases, I'm afraid I may have a heart attack"), social ("If people see me perspire, I fear they will negatively evaluate me"), and cognitive ("When I feel these symptoms, I fear it means I'm going crazy or will lose control and do something dangerous like disconnect my IV"). These thoughts stimulate the sympathetic nervous system, resulting in stronger sensations and further catastrophic misinterpretations, which may spiral into a panic attack. Strategies to address anxiety sensitivity include pharmacologic and nonpharmacologic interventions. In intensive care unit settings, anxiety sensitivity may be related to common monitoring and interventional procedures (eg, oxygen therapy, repositioning, use of urine collection systems). Anxiety sensitivity can be a barrier to weaning from mechanical ventilation when patients are uncomfortable following instructions to perform awakening or breathing trials. Fortunately, anxiety sensitivity is a malleable trait with evidence-based intervention options. However, few health care providers are aware of this psychological construct and available treatment. This article describes the nature of anxiety sensitivity, its potential impact on intensive care, how to assess and interpret scores from validated instruments such as the Anxiety Sensitivity Index, and treatment approaches across the critical care trajectory, including long-term recovery. Implications for critical care practice and future directions are also addressed.

Memory making in critical care: A qualitative thematic synthesis.

Caring for bereaved families is an important aspect of the nursing role in critical care. Memory making practices are one way in which dying, death and bereavement can be acknowledged and supported within critical care. Memory making was introduced into the care of stillborn babies and neonatal deaths to improve parents' experiences of bereavement, and has since become common practice in adult critical care. The aim of this qualitative thematic synthesis was to explore families' experiences of memory making in critical care, with a view of gaining greater understanding of the ways in which memory making impacts bereaved families. A systematic search strategy was developed, and five databases were searched (Medline, CINAHL, PsychINFO, Embase and ASSIA). Seven qualitative studies were included: four were conducted in adult and three in paediatric critical care settings in which memory making was initiated between 2014 and 2020. Memory making practices included, patient diaries, general keepsakes, word clouds and photography. The thematic synthesis generated four main themes to describe families' experience of memory making in critical care: 'connection', 'compassion', 'engagement and creation' and 'continuation'. Memory making is a meaningful activity for families whose loved one dies in critical care; it brings focus and meaning during a devastating process in a highly technical environment. Families rely heavily on nursing staff for support and guidance. The creation of memories and/or keepsakes can have a positive impact on the bereavement experience for families and can facilitate a continuing bond with their loved one. Memory making is a worthwhile practice to support and guide family bereavement within critical care. It can provide structure and purpose during an emotionally challenging transition, by supporting families to focus on a meaningful activity during a devasting time.

Pneumosepsis survival in the setting of obesity leads to persistent steatohepatitis and metabolic dysfunction.

As critical care practice evolves, the sepsis survivor population continues to expand, often with lingering inflammation in many organs, including the liver. Given the concurrently increasing population of patients with NAFLD, in this study, we aimed to understand the long-term effect of sepsis on pre-existing NAFLD and hyperglycemia. Male mice were randomized to a high-fat diet or a control diet (CD). After 24 weeks on diet, mice were inoculated with Klebsiella pneumoniae (Kpa). Serial glucose tolerance tests, and insulin and pyruvate challenge tests were performed 1 week before infection and at 2 and 6 weeks after infection. Whole tissue RNA sequencing and histological evaluation of the liver were performed. To test whether persistent inflammation could be reproduced in other abnormal liver environments, mice were also challenged with Kpa after exposure to a methionine-choline-deficient high-fat diet. Finally, a retrospective cohort of 65,139 patients was analyzed to evaluate whether obesity was associated with liver injury after sepsis. After Kpa inoculation, high-fat diet mice had normalized fasting blood glucose without a change in insulin sensitivity but with a notable decrease in pyruvate utilization. Liver examination revealed focal macrophage collections and a unique inflammatory gene signature on RNA analysis. In the clinical cohort, preobesity, and class 1 and class 2 obesity were associated with increased odds of elevated aminotransferase levels 1-2 years after sepsis. The combination of diet-induced obesity and pneumosepsis survival in a murine model resulted in unique changes in gluconeogenesis and liver inflammation, consistent with the progression of benign steatosis to steatohepatitis. In a cohort study, obese patients had an increased risk of elevated aminotransferase levels 1-2 years following sepsis.
