EXaminaTion of cRitical cAre PHArmacist pRoductivity MetricS (EXTRA‐PHARMS): The clinical pharmacist's perspective

AbstractBackgroundCritical care pharmacists are well‐established, valuable members of the intensive care unit interprofessional team with unique skills to perform comprehensive medication management in complex critically ill patients. However, standardized and consequential productivity metrics for critical care pharmacists have not been established.ObjectiveTo characterize the utilization and perception of contemporary critical care pharmacy productivity metrics utilized among individual institutions.Design, Setting, and ParticipantsAn electronic survey was distributed to critical care pharmacist members of the Society of Critical Care Medicine Clinical Pharmacy and Pharmacology Section and the American College of Clinical Pharmacy Critical Care Practice and Research Network.Main Outcomes and MeasuresThe survey included 23 questions to assess institution demographics, individual respondent demographics, institution practices, and individual respondent perceptions about the value of critical care pharmacist productivity metrics.ResultsA total of 204 critical care pharmacists, largely from the United States, responded to the survey between July and November 2022. Institutional metrics captured by more than 50% of the respondents' institutions included order verification rate/number of orders verified (60%), number of clinical interventions (57%), and intravenous to enteral product interchanges (52%). Of these metrics, critical care pharmacists only agreed with the value of the number of clinical interventions, were indifferent to the value of intravenous to oral product interchanges, and disagreed with the value of order verification rate/number of orders verified.ConclusionsSignificant discrepancies exist between institutional productivity metric practices and their perceived value and utility among critical care pharmacists.

Lung-Protective Mechanical Ventilation in Patients with Severe Acute Brain Injury: A Multicenter Randomized Clinical Trial (PROLABI).

Rationale: Lung-protective strategies using low Vt and moderate positive end-expiratory pressure (PEEP) are considered best practice in critical care, but interventional trials have never been conducted in patients with acute brain injuries because of concerns about carbon dioxide control and the effect of PEEP on cerebral hemodynamics. Objectives: To test the hypothesis that ventilation with lower VT and higher PEEP compared to conventional ventilation would improve clinical outcomes in patients with acute brain injury. Methods: In this multicenter, open-label, controlled clinical trial, 190 adult patients with acute brain injury were assigned to receive either a lung-protective or a conventional ventilatory strategy. The primary outcome was a composite endpoint of death, ventilator dependency, and acute respiratory distress syndrome (ARDS) at Day 28. Neurological outcome was assessed at ICU discharge by the Oxford Handicap Scale and at 6 months by the Glasgow Outcome Scale. Measurements and Main Results: The two study arms had similar characteristics at baseline. In the lung-protective and conventional strategy groups, using an intention-to-treat approach, the composite outcome at 28 days was 61.5% and 45.3% (relative risk [RR], 1.35; 95% confidence interval [CI], 1.03-1.79; P = 0.025). Mortality was 28.9% and 15.1% (RR, 1.91; 95% CI, 1.06-3.42; P = 0.02), ventilator dependency was 42.3% and 27.9% (RR, 1.52; 95% CI, 1.01-2.28; P = 0.039), and incidence of ARDS was 30.8% and 22.1% (RR, 1.39; 95% CI, 0.85-2.27; P = 0.179), respectively. The trial was stopped after enrolling 190 subjects because of termination of funding. Conclusions: In patients with acute brain injury without ARDS, a lung-protective ventilatory strategy, as compared with a conventional strategy, did not reduce mortality, percentage of patients weaned from mechanical ventilation, or incidence of ARDS and was not beneficial in terms of neurological outcomes. Because of the early termination, these preliminary results require confirmation in larger trials. Clinical trial registered with www.clinicaltrials.gov (NCT01690819).

Impact of different intravenous bolus rates on fluid and electrolyte balance and mortality in critically ill patients.

The effect of intravenous bolus rates on patient outcomes is a complex and crucial aspect of critical care. Fluid challenges are commonly used in critically ill patients to manage their hemodynamic status, but there is limited information available on the specifics of when, how much, and at what rate fluids should be administered during these challenges. The aim of this review is to thoroughly examine the relationship between intravenous bolus rates, fluid-electrolyte balance, and mortality and to analyze key research findings and methodologies to understand these complex dynamics better. Fluid challenges are commonly employed in managing hemodynamic status in this population, yet there is limited information on the optimal timing, volume, and rate of fluid administration. Utilizing a narrative review approach, the analysis identified nine relevant studies that investigate these variables. The findings underscore the importance of a precise and individualized approach in clinical settings, highlighting the need to tailor intravenous bolus rates to each patient's specific needs to maximize outcomes. This review provides valuable insights that can inform and optimize clinical practices in critical care, emphasizing the necessity of meticulous and exact strategies in fluid administration.

Maternal Sepsis.

Sepsis is the second leading cause of pregnancy-related mortality in the United States. Early recognition, treatment, and escalation of care for the obstetric patient affected by sepsis mitigate the risk of mortality and improve patient outcomes. In this article, we provide an overview of maternal sepsis and address topics of maternal pathophysiology, early warning signs, diagnostic criteria, early goal-directed therapy, and contemporary critical care practices. We also present an overview of common etiologies of maternal sepsis and suggested treatment approaches.

A Comprehensive Review of the Role of Magnesium in Critical Care Pediatrics: Mechanisms, Clinical Impact, and Therapeutic Strategies.

Magnesium is an essential mineral with pivotal roles in various physiological processes, including enzyme function, neuromuscular regulation, and cardiovascular health. Magnesium's importance in critically ill pediatric patients is magnified due to its involvement in maintaining cellular homeostasis and potential therapeutic benefits. This review comprehensively analyzes magnesium's role in critical care pediatrics, focusing on its physiological mechanisms, clinical impact, and therapeutic strategies. Magnesium's functions in energy production, protein synthesis, and electrolyte balance underscore its significance in critical illness, where imbalances can lead to severe complications such as arrhythmias, neuromuscular disturbances, and respiratory issues. The review examines the clinical consequences of magnesium deficiency, including its impact on various body systems and the potential exacerbation of critical conditions. It also explores therapeutic strategies to optimize patient care, including supplementation practices, dosing considerations, and monitoring protocols. By summarizing recent research and clinical guidelines, this review aims to enhance understanding of magnesium's role in critical care and provide evidence-based recommendations for its management. The insights provided are intended to guide clinicians in integrating magnesium therapy into critical care practices, ultimately improving patient outcomes and advancing the management of critically ill pediatric patients.

Looking to "Level the Field": A Qualitative Study of How Clinicians Operationalize Social Determinants in Critical Care.

Current critical care practice does not integrate social determinants of health (SDOH) in systematic or standardized ways. Routine assessment of SDOH in the intensive care unit (ICU) may improve clinical decision-making, patient- and family-centered outcomes, and clinician well-being. Given the appropriateness and feasibility of SDOH assessment in the ICU is unknown, we aimed to understand how ICU clinicians think about and use SDOH. We conducted semi-structured interviews with clinicians focused on barriers to and facilitators of assessing SDOH during critical illness and perceptions on screening for SDOH in the ICU. We used chart-stimulated recall to assist clinicians in reflecting on how SDOH applied to and was used in patients' care. After deidentifying interviews, we analyzed transcripts guided by a thematic analysis approach using a combination of inductive and deductive coding, the latter framed within the Centers for Disease Control SDOH Healthy People framework. We completed interviews with 30 clinicians, in a variety of professional roles. The majority of clinicians self-identified as men (17, 56.7%) of White race (25, 83.3%). Clinicians contextualize their use of SDOH within three frames of reference: 1) their own identity and experiences; 2) their relationships and communication with patients and caregivers; and 3) immediate structures of care around ICU patients including clinician advocacy, care transitions, and readmission. Clinicians identified that discussing SDOH could allow them to recognize bias faced by their patients, elucidate drivers of critical illness, and navigate communication with patients caregivers. Clinicians worried about ICU-specific factors impeding the discussion of SDOH including time contraints and acuity, high stakes and emotions, and negative anticipatory emotions. Clinicians gather SDOH during critical illness both to understand their patients' stories and provide individualized care, which may lead to better clinician satisfaction and patient- and family-centered care outcomes. Educational and operational efforts to increase SDOH assessment and use in critical care should also gather and integrate the perspectives of patients and caregivers regarding the collection and use of SDOH in the ICU.

Factors influencing knowledge translation into critical care practice: The reality facing intensive care nurses in Limpopo Province

Background. Nurses working in intensive care units (ICUs) must incorporate new knowledge and evidence-based practice (EBP) into their daily routines to enhance patient outcomes. However, this integration often falls short in ICU settings. Weekly clinical audits reveal incidents where ICU nurses neglect evidence-based interventions, impacting patient outcomes and ICU stays. Objective. To explore the factors influencing the translation of knowledge into ICU practice. Methods. We conducted exploratory, qualitative research to investigate ICU nurses’ perspectives on knowledge translation into ICU practices. The study employed purposive sampling to select ICU nurses. We used paired interviews and group discussions to gather insights from ICU nurses regarding the factors influencing the translation of knowledge into ICU practices. Data analysis was performed using Boomer and McCormack’s nine steps of creative hermeneutic data analysis. Results. One main theme, ‘We are just surviving’ emerged, encompassing two sub-themes: management and workplace culture. Under management, participants described barriers, such as resource scarcity, behaviour, outdated evidence-informed protocols and workload. Under workplace culture, participants mentioned negative attitudes and a lack of teamwork, contributing to poor-quality care. Conclusion. In ICUs, nurses are expected to integrate new knowledge and scientific evidence into their daily practice, yet they face challenges in doing so. Interventions should be implemented to address management and workplace culture.

Perspectives of Clinical Instructors of Nursing Student Competences in Acute and Critical Care

Nursing students must be competent in providing acute and critical care. This study investigated the perspectives of clinical instructors on these competencies in challenging nursing environments. Ten clinical instructors from the Regional Hospital of Semarang City, Central Java, Indonesia, participated in this study to observe students during their clinical practice in acute and critical care. Qualitative data was collected between May and December 2020. Face-to-face and virtual in-depth interviews lasted 30 to 40 minutes per informant. Data validity was ensured by member verification, which involved participants reviewing the recorded interviews. The nursing competency perspectives were divided into nine themes: (1) addressing biological, psychological, social, and spiritual needs; (2) involving families in patient care; (3) integrating attitudes, morals, and ethics; (4) developing communication skills; (5) working in multidisciplinary teams and complementary therapies; (6) effectively managing emergencies effectively; (7) recognizing and addressing spiritual aspects; (8) developing critical thinking and technology mastery; and (9) improving quality. This study’s findings serve as a valuable reference and guide for refining nursing student competencies in acute and critical care and creating assessment instruments.

Undergraduate Student Nurses' Satisfaction, Self-confidence, and Perception of High-fidelity Simulation-based Learning on Critically-ill Patients.

Replicating critical care practice settings in high-fidelity simulation (HFS) provides more learning opportunities to develop competencies, improve self-confidence, and learner satisfaction in a safe environment. Simulation is increasingly adopted globally as an alternative teaching strategy. Yet, data on the HFS experience of Filipino undergraduate nursing students is limited. This study describes the satisfaction, self-confidence, and perception of undergraduate nursing students on the use of HFS-based learning on critically-ill adult and pediatric patients requiring advanced life support (ALS). A quantitative, descriptive, correlational study was conducted using purposive sampling on all fourth-year BS Nursing students enrolled in Critical Care Nursing course in a state university. Data were collected through an online survey on demographic data, and the students' perceptions towards high-fidelity simulation-based learning (SBL) using three tools, namely: Simulation Design Scale, Educational Practices Questionnaire, and Student Satisfaction and Self-confidence in Learning. T-test and ANOVA were used to compare the means of the variables. Bivariate analysis (Pearson's product-moment correlation) was performed to find the relationship between variables. A total of 86 students participated in the survey. Overall, the students were highly satisfied with the simulation experience (4.46 out of 5.0, SD=0.47), and had high ratings of self-confidence in SBL (4.44 out of 5.0, SD=0.42). Overall satisfaction level was positively related to student's perception on simulation design (r=0.61, p<0.01) and educational practices (r=0.59, p<0.01). Similarly, the students' overall self-confidence with SBL was also positively correlated with their perceptions of the simulation design (r=0.32, p<0.01), and educational practices (r=0.34, p<0.01). Effective use of technology through HFS-based learning is useful in increasing satisfaction and self-confidence of Filipino undergraduate nursing students in caring for critically-ill patients needing ALS. Educators must highly consider all parameters of simulation design and educational practices in planning and implementing HFS-based learning to achieve meaningful learner experience.

Similarities and differences between intermittent hemodialysis and sustained low-efficiency dialysis

Abstract Acute kidney injury (AKI) is a multifaceted syndrome with diverse etiologies encountered very frequently in all critical care service units. Time and again, multiple researchers have proven its independent contribution to increasing morbidity and mortality in hospitalized children and adults. This undeniable fact has guided the development of newer strategies and logical concepts that have led to new modalities of treating AKI. In the absence of curative medical therapy, kidney replacement therapy (KRT) is considered the primary supportive therapy for AKI, and when initiated at the right time, it has the potential to bridge the gap toward cure. Among all KRT methods, blood-based dialysis occupies a prominent role and has now become the cornerstone of treatment for critically ill children with AKI. Two major methods usually employed are “intermittent hemolysis” (IHD) and “continuous kidney replacement therapy” (CKRT). Currently, a third method called “sustained low-efficiency dialysis (SLED)” is gaining momentum in critical care. It is a hybrid method; in simpler terms, it is a slow and prolonged IHD that may carry a few of the critical merits of CKRT. This narrative review article sheds light on SLED, as well as its comparison to IHD in critical care practice.

Critical care pharmacist perspectives on optimal practice models and prioritization of professional activities: A cross-sectional survey

Abstract Disclaimer In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time. Purpose Critical care pharmacists (CCPs) are essential members of the multidisciplinary critical care team. Professional activities of the CCP are outlined in a 2020 position paper on critical care pharmacy services. This study looks to characterize CCP perspectives for priorities in optimizing pharmacy practice models and professional activities. Methods This was a cross-sectional survey conducted from July 24 to September 20, 2023. A 41-question survey instrument was developed to assess 7 domains: demographics, CCP resource utilization, patient care, quality improvement, research and scholarship, training and education, and professional development. This voluntary survey was sent to members of the American College of Clinical Pharmacy’s Critical Care Practice and Research Network. The survey was open for a total of 6 weeks. Results There was a response rate of 20.7% (332 of 1,605 invitees), with 66.6% of respondents (n = 221) completing at least 90% of the survey questions. Most respondents were clinical specialists (58.2%) and/or practiced at an academic medical center (58.5%). Direct patient care, quality improvement and medication safety, and teaching and precepting were identified as the CCP activities of highest importance to CCPs. The CCP-to-patient ratios considered ideal were 1:11-15 (selected by 49.8% of respondents) and 1:16-20 (33.9% of respondents). The ideal percentage of time dedicated to direct patient care activities, as identified by survey respondents, was 50% (interquartile range, 40-50). Conclusion These findings highlight the professional activities viewed as having the highest priority by CCPs. Future research is needed to define optimal CCP practice models for the delivery of patient care in real-world settings.

Ten misconceptions regarding decision-making in critical care

Diagnostic errors are prevalent in critical care practice and are associated with patient harm and costs for providers and the healthcare system. Patient complexity, illness severity, and the urgency in initiating proper treatment all contribute to decision-making errors. Clinician-related factors such as fatigue, cognitive overload, and inexperience further interfere with effective decision-making. Cognitive science has provided insight into the clinical decision-making process that can be used to reduce error. This evidence-based review discusses ten common misconceptions regarding critical care decision-making. By understanding how practitioners make clinical decisions and examining how errors occur, strategies may be developed and implemented to decrease errors in Decision-making and improve patient outcomes.

The road less traveled: Developing pharmacist clinician-scientists through divergent training pathways.

Professional organizations have emphasized the growing need for pharmacists to possess advanced research skills; however, there is a scarcity of training programs aimed at nurturing clinician-scientists. This report outlines 3 critical care-focused research programs, each offering a unique approach to training clinician-scientists. Limited resources and formalized programs are available to bridge the gap between the demand for and availability of skilled clinician-scientists. Several programs have stepped forward to share their experiences in establishing and executing training initiatives aimed at cultivating skilled clinician-scientists in the critical care practice space. Enhancing the development of clinician-scientists for clinical and translational research is necessary in the critical care clinical pharmacy community.

Heterogeneity, Bayesian thinking, and phenotyping in critical care: A primer.

To familiarize clinicians with the emerging concepts in critical care research of Bayesian thinking and personalized medicine through phenotyping and explain their clinical relevance by highlighting how they address the issues of frequent negative trials and heterogeneity of treatment effect. The past decades have seen many negative (effect-neutral) critical care trials of promising interventions, culminating in calls to improve the field's research through adopting Bayesian thinking and increasing personalization of critical care medicine through phenotyping. Bayesian analyses add interpretive power for clinicians as they summarize treatment effects based on probabilities of benefit or harm, contrasting with conventional frequentist statistics that either affirm or reject a null hypothesis. Critical care trials are beginning to include prospective Bayesian analyses, and many trials have undergone reanalysis with Bayesian methods. Phenotyping seeks to identify treatable traits to target interventions to patients expected to derive benefit. Phenotyping and subphenotyping have gained prominence in the most syndromic and heterogenous critical care disease states, acute respiratory distress syndrome and sepsis. Grouping of patients has been informative across a spectrum of clinically observable physiological parameters, biomarkers, and genomic data. Bayesian thinking and phenotyping are emerging as elements of adaptive clinical trials and predictive enrichment, paving the way for a new era of high-quality evidence. These concepts share a common goal, sifting through the noise of heterogeneity in critical care to increase the value of existing and future research. The future of critical care medicine will inevitably involve modification of statistical methods through Bayesian analyses and targeted therapeutics via phenotyping. Clinicians must be familiar with these systems that support recommendations to improve decision-making in the gray areas of critical care practice.

Expert consensus on the application of critical care ultrasonography in invasive procedures

The evolution of critical care medicine is inextricably linked to the development of critical care procedures. These procedures not only facilitate diagnosis and treatment of critically ill patients, but also provide valuable insights into disease pathophysiology. While critical care interventions offer undeniable benefits, the potential for iatrogenic complications necessitates careful consideration. The recent surge in critical care ultrasound (US) utilization is a testament to its unique advantages: non-invasiveness, real-time bedside availability, direct visualization of internal structures, elimination of ionizing radiation exposure, repeatability, and relative ease of learning. Recognizing the need to optimize procedures and minimize complications, critical care utrasound study group of Beijing critical care ultrasound research assocition convened a panel of critical care experts to generate this consensus statement. This document serves as a guide for healthcare providers, aiming to ensure patient safety and best practices in critical care.

Problematic meta-analyses: Bayesian and frequentist perspectives on combining randomized controlled trials and non-randomized studies

PurposeIn the literature, the propriety of the meta-analytic treatment-effect produced by combining randomized controlled trials (RCT) and non-randomized studies (NRS) is questioned, given the inherent confounding in NRS that may bias the meta-analysis. The current study compared an implicitly principled pooled Bayesian meta-analytic treatment-effect with that of frequentist pooling of RCT and NRS to determine how well each approach handled the NRS bias.Materials & methodsBinary outcome Critical-Care meta-analyses, reflecting the importance of such outcomes in Critical-Care practice, combining RCT and NRS were identified electronically. Bayesian pooled treatment-effect and 95% credible-intervals (BCrI), posterior model probabilities indicating model plausibility and Bayes-factors (BF) were estimated using an informative heavy-tailed heterogeneity prior (half-Cauchy). Preference for pooling of RCT and NRS was indicated for Bayes-factors > 3 or < 0.333 for the converse. All pooled frequentist treatment-effects and 95% confidence intervals (FCI) were re-estimated using the popular DerSimonian-Laird (DSL) random effects model.ResultsFifty meta-analyses were identified (2009–2021), reporting pooled estimates in 44; 29 were pharmaceutical-therapeutic and 21 were non-pharmaceutical therapeutic. Re-computed pooled DSL FCI excluded the null (OR or RR = 1) in 86% (43/50). In 18 meta-analyses there was an agreement between FCI and BCrI in excluding the null. In 23 meta-analyses where FCI excluded the null, BCrI embraced the null. BF supported a pooled model in 27 meta-analyses and separate models in 4. The highest density of the posterior model probabilities for 0.333 < Bayes factor < 1 was 0.8.ConclusionsIn the current meta-analytic cohort, an integrated and multifaceted Bayesian approach gave support to including NRS in a pooled-estimate model. Conversely, caution should attend the reporting of naïve frequentist pooled, RCT and NRS, meta-analytic treatment effects.

Bedside critical care training: A quasi-experimental study in the paediatric emergency department of a referral hospital in Nigeria.

There is a need for critical care services outside intensive care units (ICUs), especially in emergency departments (EDs). However, there is a paucity of skilled manpower for ED critical care or emergency critical care (ECC) in resource-limited settings. To evaluate the impact of bedside training on emergency critical care practices of clinical staff. This was a quasi-experimental study using a pretest - post-test design in a paediatric ED. The intervention was a six-week structured bedside training on bubble continuous positive airway pressure (CPAP) high-flow nasal cannula (HFNC) and mechanical ventilation. Participants' actual ECC practices pre and post training were evaluated, including their perceived proficiency on an uncalibrated 100 mm visual analogue scale (VAS). Descriptive and inferential analyses were done; p<0.05 was considered significant. A total of 35 clinical staff participated in the training, comprising 9 (24.3%) paediatric registrars, 12 (32.5%) senior registrars, 10 (27.0%) nurses, 4 (10.8%) house officers and 2 (5.4%) paediatric consultants. The male:female ratio of the participants was 1:1.6, and their mean (SD) age was 33.24 (6.30 years. Participants' understanding of testing the CPAP circuit, connecting the patient and weaning significantly improved following training (p=0.004). Their capacity to select appropriate HFNC parameters improved (p=0.013). They performed more endotracheal intubations in the post-training period (p=0.001). Their pretest-post-test proficiency in mechanical ventilation increased on VAS (mean scores 45.26+31.99 v. 63.26+22.26; p=0.038). Also, there was a significant increase in their perceived proficiency in paediatric analgesia/sedation (30.83+29.86 v. 49.83+23.90; p=0.029). Short-term bedside critical care training enhanced the self-reported competency of paediatric ED staff. There is a need for on-the-job ECC training and retraining of clinical staff in our setting. Paediatric emergency department clinical staff desire hands-on critical care training in developing settings. Bedside training improves the knowledge and skills of nursing staff in non-invasive ventilation. Bedside training also builds the capacity of medical staff in invasive ventilation in the emergency department. Overall, short-term bedside training enhances the clinical knowledge and self-reported critical care practice of clinical staff in Children's Emergency Room.

Web-accessible critical limits and critical values for urgent clinician notification.

To survey the World Wide Web for critical limits/critical values, assess changes in quantitative low/high thresholds since 1990-93, streamline urgent notification practices, and promote global accessibility. We identified Web-posted lists of critical limits/values at university hospitals. We compared 2023 to 1990-93 archived notification thresholds. We found critical notification lists for 26 university hospitals. Laboratory disciplines ranged widely (1-10). The median number of tests was 62 (range 21-116); several posted policies. The breadth of listings increased. Statistically significant differences in 2023 vs. 1990 critical limits were observed for blood gas (pO2, pCO2), chemistry (glucose, calcium, magnesium), and hematology (hemoglobin, platelets, PTT, WBC) tests, and for newborn glucose, potassium, pO2, and hematocrit. Twenty hospitals listed ionized calcium critical limits, which have not changed. Fourteen listed troponin (6), troponin I (3), hs-TnI (3), or troponin T (2). Qualitative critical values expanded across disciplines, encompassing anatomic/surgical pathology. Bioterrorism agents were listed frequently, as were contagious pathogens, although only three hospitals listed COVID-19. Only one notification list detailed point-of-care tests. Two children's hospital lists were Web-accessible. Urgent notifications should focus on life-threatening conditions. We recommend that hospital staff evaluate changes over the past three decades for clinical impact. Notification lists expanded, especially qualitative tests, suggesting that automation might improve efficiency. Sharing notification lists and policies on the Web will improve accessibility. If not dependent on the limited scope of secondary sources, artificial intelligence could enhance knowledge of urgent notification and critical care practices in the 21st Century.
