RESUMEN
The COVID-19 pandemic caused tremendous disruption to the U.S. healthcare system and nearly crippled some hospitals during large patient surges. Limited ICU beds across the country further exacerbated these challenges. Telemedicine, specifically tele-critical care (TCC), can expand a hospital's clinical capabilities through remote expertise and increase capacity by offloading some monitoring to remote teams. Unfortunately, the rapid deployment of telemedicine, especially TCC, is constrained by multiple barriers. In the summer of 2020, to support the National Emergency Tele-Critical Care Network (NETCCN) deployment, more than 50 national leaders in applying telemedicine technologies to critical care assembled to provide their opinions about barriers to NETCCN implementation and strategies to overcome them. Through consensus, these experts developed white papers that formed the basis of this article. Herein, the authors share their experience and propose multiple solutions to barriers presented by laws, local policies and cultures, and individual perspectives according to a minimum, better, best paradigm for TCC delivery in the setting of a national disaster. Cross-state licensure and local privileging of virtual experts were identified as the most significant barriers to rapid deployment of services, whereas refining the model of TCC to achieve the best outcomes and defining the best financial model is the most significant for long-term success. Ultimately, we conclude that a rapidly deployable national telemedicine response system is achievable.

PURPOSE OF REVIEW: This article summarizes recent developments in the application of telemedicine, specifically tele-critical care (TCC), toward enhancing patient care during various types of emergencies and patient rescue scenarios when there are limited resources in terms of staff expertise (i.e., knowledge, skills, and abilities), staffing numbers, space, and supplies due to patient location (e.g., a non-ICU bed, the emergency department, a rural hospital) or patient volume as in pandemic surges. RECENT FINDINGS: The COVID-19 pandemic demonstrated the need for rapidly scalable and agile healthcare delivery systems. During the pandemic, clinicians and hospital systems adopted telemedicine for various applications. Taking advantage of technological improvements in cellular networks and personal mobile devices, and despite the limited outcomes literature to support its use, telemedicine was rapidly adopted to address the fundamental challenge of exposure in outpatient settings, emergency departments, patient follow-up, and home-based monitoring. A critical recognition was that the modality of care (e.g., remote vs. in-person) was less important than access to care, regardless of the patient outcomes. This fundamental shift, facilitated by policies that followed emergency declarations, provided an opportunity to maintain and, in many cases, expand and improve clinical practices and hospital systems by bringing expertise to the patient rather than the patient to the expertise. In addition to using telemedicine to maintain patient access to healthcare, TCC was harnessed to provide local clinicians, forced to manage critically ill patients beyond their normal scope of practice or experience, access to remote expertise (physician, nursing, respiratory therapist, pharmacist). These practices supported decades of literature from the telemedicine community describing the effectiveness of telemedicine in improving patient care and the many challenges defining its value. SUMMARY: In this review, we summarize numerous examples of innovative care delivery systems that have utilized telemedicine, focusing on 'mobile' TCC technology solutions to effectively deliver the best care to the patient regardless of patient location. We emphasize how a 'paradigm of better' can enhance the entirety of the healthcare system.

OBJECTIVES: To explore gamification as an alternative approach to healthcare education and its potential applications to critical care. DATA SOURCES: 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). STUDY SELECTION: 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 EXTRACTION: 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. DATA SYNTHESIS: 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. CONCLUSIONS: 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.
RESUMEN
Background: In December 2021, the Region 1 Disaster Health Response System, the state of Vermont, and the National Emergency Tele-Critical Care Network partnered to provide statewide access to disaster teleconsultations during COVID-19 surge conditions. In this case report, we describe how a disaster teleconsultation system was implemented in Vermont to provide access to temporary tele-critical care consultations during the Omicron COVID-19 surge. Methods: We measured the time from request of service to implementation and calculated descriptive statistics. Results: Seven of Vermont's 14 hospitals requested the service. Despite a technology solution capable of providing services within hours, mean time to service implementation was 27 days (interquartile range 20-41 days). Conclusions: Integration of disaster teleconsultation systems into state and local emergency management plans are needed to bring administrative start-up times in line with technical readiness.
RESUMEN
OBJECTIVES: In 2014, the Tele-ICU Committee of the Society of Critical Care Medicine published an article regarding the state of ICU telemedicine, one better defined today as tele-critical care. Given the rapid evolution in the field, the authors now provide an updated review. DATA SOURCES AND STUDY SELECTION: We searched PubMed and OVID for peer-reviewed literature published between 2010 and 2018 related to significant developments in tele-critical care, including its prevalence, function, activity, and technologies. Search terms included electronic ICU, tele-ICU, critical care telemedicine, and ICU telemedicine with appropriate descriptors relevant to each sub-section. Additionally, information from surveys done by the Society of Critical Care Medicine was included given the relevance to the discussion and was referenced accordingly. DATA EXTRACTION AND DATA SYNTHESIS: Tele-critical care continues to evolve in multiple domains, including organizational structure, technologies, expanded-use case scenarios, and novel applications. Insights have been gained in economic impact and human and organizational factors affecting tele-critical care delivery. Legislation and credentialing continue to significantly influence the pace of tele-critical care growth and adoption. CONCLUSIONS: Tele-critical care is an established mechanism to leverage critical care expertise to ICUs and beyond, but systematic research comparing different models, approaches, and technologies is still needed.

BACKGROUND AND AIMS: Alagille syndrome (ALGS) is a multisystem developmental disorder characterized by bile duct (BD) paucity, caused primarily by haploinsufficiency of the Notch ligand jagged1. The course of the liver disease is highly variable in ALGS. However, the genetic basis for ALGS phenotypic variability is unknown. Previous studies have reported decreased expression of the transcription factor SOX9 (sex determining region Y-box 9) in late embryonic and neonatal livers of Jag1-deficient mice. Here, we investigated the effects of altering the Sox9 gene dosage on the severity of liver disease in an ALGS mouse model. APPROACH AND RESULTS: Conditional removal of one copy of Sox9 in Jag1+/- livers impairs the biliary commitment of cholangiocytes and enhances the inflammatory reaction and liver fibrosis. Loss of both copies of Sox9 in Jag1+/- livers further worsens the phenotypes and results in partial lethality. Ink injection experiments reveal impaired biliary tree formation in the periphery of P30 Jag1+/- livers, which is improved by 5 months of age. Sox9 heterozygosity worsens the P30 biliary tree phenotype and impairs the partial recovery in 5-month-old animals. Notably, Sox9 overexpression improves BD paucity and liver phenotypes in Jag1+/- mice without ectopic hepatocyte-to-cholangiocyte transdifferentiation or long-term liver abnormalities. Notch2 expression in the liver is increased following Sox9 overexpression, and SOX9 binds the Notch2 regulatory region in the liver. Histological analysis shows a correlation between the level and pattern of SOX9 expression in the liver and outcome of the liver disease in patients with ALGS. CONCLUSIONS: Our results establish Sox9 as a dosage-sensitive modifier of Jag1+/- liver phenotypes with a permissive role in biliary development. Our data further suggest that liver-specific increase in SOX9 levels is a potential therapeutic approach for BD paucity in ALGS.

PURPOSE: In shock, hypotension may contribute to inadequate oxygen delivery, organ failure and death. We conducted the Optimal Vasopressor Titration (OVATION) pilot trial to inform the design of a larger trial examining the effect of lower versus higher mean arterial pressure (MAP) targets for vasopressor therapy in shock. METHODS: We randomly assigned critically ill patients who were presumed to suffer from vasodilatory shock regardless of admission diagnosis to a lower (60-65 mmHg) versus a higher (75-80 mmHg) MAP target. The primary objective was to measure the separation in MAP between groups. We also recorded days with protocol deviations, enrolment rate, cardiac arrhythmias and mortality for prespecified subgroups. RESULTS: A total of 118 patients were enrolled from 11 centres (2.3 patients/site/month of screening). The between-group separation in MAP was 9 mmHg (95% CI 7-11). In the lower and higher MAP groups, we observed deviations on 12 versus 8% of all days on vasopressors (p = 0.059). Risks of cardiac arrhythmias (20 versus 36%, p = 0.07) and hospital mortality (30 versus 33%, p = 0.84) were not different between lower and higher MAP arms. Among patients aged 75 years or older, a lower MAP target was associated with reduced hospital mortality (13 versus 60%, p = 0.03) but not in younger patients. CONCLUSIONS: This pilot study supports the feasibility of a large trial comparing lower versus higher MAP targets for shock. Further research may help delineate the reasons for vasopressor dosing in excess of prescribed targets and how individual patient characteristics modify the response to vasopressor therapy.

OBJECTIVES: To review the growth and current penetration of ICU telemedicine programs, association with outcomes, studies of their impact on medical education, associations with medicolegal risks, identify program revenue sources and costs, regulatory aspects, and the ICU telemedicine research agenda. DATA SOURCES: Review of the published medical literature, governmental documents, and opinions of experts from the Society of Critical Care Medicine ICU Telemedicine Committee. DATA SYNTHESIS: Formal ICU telemedicine programs now support 11% of nonfederal hospital critically ill adult patients. There is increasingly robust evidence of association with lower ICU (0.79; 95% CI, 0.65-0.96) and hospital mortality (0.83; 95% CI, 0.73-0.94) and shorter ICU (-0.62 d; 95% CI, -1.21 to -0.04 d) and hospital (-1.26 d; 95% CI, -2.49 to -0.03 d) length of stay. Physicians in training report experiences with telemedicine intensivists that are positive and increased patient safety. Early studies suggest that implementation of ICU telemedicine programs has been associated with lower numbers of malpractice claims and costs. The requirements for Medicare reimbursement and states with legislation addressing providing professional services by telemedicine are detailed. CONCLUSIONS: The inclusion of an ICU telemedicine program as a major part of their critical care delivery paradigm has been implemented for 11% of critically ill U.S. adults as a solution for the problem of access to adult critical care services. Implementation of an ICU telemedicine program is one practical way to increase access and reduce mortality as well as length of stay. ICU telemedicine research including comparative effectiveness studies is urgently needed.

OBJECTIVE: The optimal role of vasopressor therapy in septic shock is not known. We hypothesized that the variability in the use of vasopressors to treat hypotension is associated with subsequent organ failures. DESIGN: Retrospective observational single-center cohort study. SETTING: Tertiary care hospital. PATIENTS AND PARTICIPANTS: Consecutive patients with septic shock. MEASUREMENT AND RESULTS: Ninety-five patients were enrolled. Serial blood pressure recordings and vasopressor use were collected during the first 12h of septic shock. Median duration of hypotension that was not treated with vasopressors was 1.37h (interquartile range [IQR] 0.62-2.66). Based on the observed variability, we evaluated liberal (duration of untreated hypotension < median) vs. conservative (duration of untreated hypotensionn > median) vasopressor therapy. Compared with patients who received conservative vasopressor therapy, patients treated liberally had similar baseline organ impairment [median Sequential Organ Failure Assessment (SOFA) score 8 vs. 8, p = 0.438] were more likely to be younger (median age 70 vs. 77 years, p = 0.049), to require ventilator support (78 vs. 49%, p < 0.001), and to have progression of organ failures after 24h (59 vs. 37%, p = 0.032). When adjusted for age and mechanical ventilation, early therapy aimed at achieving global tissue perfusion [odds ratio (OR) 0.33, 95% confidence interval (CI) 0.11-0.88), and early adequate antibiotic therapy (OR 0.27, 95% CI 0.09-0.76), but not liberal vasopressor use (OR 2.13, 95% CI 0.80-5.84), prevented progression of organ failures. CONCLUSIONS: In our retrospective study, early adequate antibiotics and achieving adequate global perfusion, but not liberal vasopressor therapy, were associated with improved organ failures after septic shock. Clinical trials which compare conservative vs. liberal vasopressor therapy are warranted.

This article discusses the pathophysiology and treatment of common fluid and electrolyte disorders in the ICU. The presence of oliguria should alert the intensivist to identify the underlying cause rather than to resort reflexively to measures, such as diuretics or dopamine, to establish urine flow. Hypo- and hypernatremia, which are exceedingly commonly in the ICU setting, also are discussed using a pathophysiologic approach.

Sepsis and septic shock are the leading causes of acute renal failure, multiple organ system dysfunction, and death in the intensive care unit. The pathogenesis of sepsis is complex and comprises a mosaic of interconnected pathways. Several attempts to improve patient outcomes by targeting specific components of this network have been unsuccessful. For these reasons, the ideal immunomodulating strategy would be one that restores immunologic stability rather than blindly inhibiting or stimulating one or another component of this complex network. Hence, the recent focus of immunomodulatory therapy in sepsis has shifted to nonspecific methods of influencing the entire inflammatory response without suppressing it. Here, we discuss the various modalities of extracorporeal blood purification, the existing evidence, and future prospects.

BACKGROUND: Considerable controversy exists as to whether synthetic (more biocompatible) dialysis membranes improve outcome in patients with acute renal failure (ARF) compared to cellulose-based membranes. Numerous trials conducted have yielded inconsistent results. Although the discordant results of existing studies could be explained by the varying degrees of biocompatibility among the different membranes used, these studies also had low statistical power. Thus, we sought to determine whether combining results from all published trials would provide a better estimate of the effect of membrane composition on survival in ARF. METHODS: We performed a meta-analysis of all previously published prospective trials comparing the use of synthetic membranes with cellulose-based membranes for hemodialysis in patients with ARF. RESULTS: Of the 10 prospective trials identified, eight trials (867 patients) provided survival data and six trials (641 patients) provided data on recovery of renal function. We used the Mantel-Haenszel test based on a fixed effects model to analyze the data. The cumulative odds ratio (OR) for survival in favor of synthetic membranes was 1.37 (95% CI: 1.02 to 1.83), P = 0.03 and that for renal recovery was 1.23 (95% CI: 0.90 to 1.68), P = 0.18. We performed a sensitivity analysis by stratifying studies on the basis of control group membrane type (unsubstituted or substituted cellulose) and found that the survival advantage for synthetic membranes was mainly limited to comparison with the unsubstituted cellulose group [OR 1.64 (95% CI: 1.10 to 2.45) vs. OR 1.20 (95% CI: 0.73 to 1.97)]. CONCLUSIONS: Synthetic membranes appear to confer a significant survival advantage over cellulose-based membranes. We could not demonstrate a similar benefit with use of synthetic membranes over cellulose-based membranes for recovery of renal function but sample size was limited. Finally, our results suggest that the survival disadvantage for cellulose-based membranes may be limited to unsubstituted cellulose (cuprophane) membranes.
