  Yu-Chang YEHTaiwan Moderator Clinical Support Information with Generative AI: Content Generation and Evaluation Generative artificial intelligence is shifting from single-question answering toward structured clinical decision support at the bedside. This lecture presents a practical approach to generating and evaluating AI-derived clinical support information in critical care. On the generation side, we describe a multi-turn conversation and multi-task workflow in which structured patient data, a machine learning mortality prediction model, and SHAP-based explanations are passed sequentially to a large language model through five linked task prompts covering risk interpretation, syndrome identification, current status and diagnoses, recommended examinations, and management suggestions. Each turn inherits the context of the previous one, so the output accumulates into a coherent clinical narrative rather than a set of isolated answers. On the evaluation side, we introduce the IMPACT Framework, a six-domain, 21-item instrument developed through a multinational Delphi consensus involving 58 panelists from 12 countries. Its domains, Integration, Mastery, Precision, Applicability, Comprehensiveness, and Timeliness, allow both clinicians and automated judges to score generated content reproducibly. We share validation results, examples from an intensive care cohort, and lessons learned from iterative prompt refinement. Attendees will leave with a transferable method for building and auditing generative AI support tools in their own units.

  Yen-Ta HuangTaiwan Moderator From Guidelines to Bayesian Trials: How Should We Interpret Polymyxin B Hemoadsorption in Sepsis?Polymyxin B hemoadsorption has occupied an unusually contested place in sepsis care, and the way authoritative bodies describe it has shifted over time. This talk traces that evolution—from the 2020 Taiwan AKI consensus through the 2021 and 2026 Surviving Sepsis Campaign guidelines—and uses the changing recommendations as a lens on the methodological debates that underlie them. From an evidence-based medicine standpoint, the controversy is less about the device than about how we generate and grade evidence. I will first examine the frequentist evidence base, including our network meta-analysis of blood purification therapies for severe infection and sepsis/septic shock published in Critical Care Medicine. I will outline what a network meta-analysis adds—coherent ranking across multiple modalities, indirect comparison, and explicit quantification of heterogeneity—while being candid about its limitations, including reliance on the transitivity assumption, sparse networks, and the fragility of mortality estimates pooled from heterogeneous trials. I will then turn to the recently reported TIGRIS trial, which used a Bayesian, enrichment-based phase 3 design with prespecified borrowing from the EUPHRATES treatable cohort. I will highlight the strengths of the Bayesian presentation—direct posterior probabilities of benefit, transparent incorporation of prior evidence, and efficiency in a rare, mechanistically defined phenotype—alongside the cautions it demands: sensitivity to prior choice, the open-label design, and the gap between a high posterior probability and a confirmed effect. Bringing these strands together, the talk offers a multifaceted, methodology-driven reading of polymyxin B hemoadsorption in sepsis, and a transferable framework for clinicians facing the increasingly common situation in which guidelines, frequentist syntheses, and Bayesian trials appear to diverge.從治療執行到品質治理：連結式重症腎臟照護與資料驅動決策

• Organ Crosstalk in AKI
  Kent DoiJapan Speaker Organ Crosstalk in AKIAcute kidney injury (AKI) is frequently complicated by distant organ dysfunction, significantly increasing patient morbidity and mortality. Recent clinical and experimental evidence highlights complex inter-organ crosstalk mechanisms, such as systemic cytokine release, oxidative stress, immune dysregulation, and damage-associated molecular patterns (DAMPs), that mediate extrarenal tissue injury. Experimental studies demonstrate distinct pathophysiological axes connecting the injured kidney with the heart and lungs. Specifically, mitochondrial dysfunction plays a critical role in acute cardiorenal syndrome. Furthermore, in AKI-induced acute lung injury, in addition to activation of the HMGB1–Toll-like receptor 4 (TLR4) pathway and formation of neutrophil extracellular traps (NETs), recent studies have reported a novel pathophysiological mechanism of impaired gas exchange mediated by neutrophil retention. This presentation provides an updated overview of the molecular pathways driving AKI-induced distant organ crosstalk, emphasizing key pathophysiology involving the heart and lungs, and discusses targeted therapeutic strategies to improve clinical outcomes in multi-organ failure.Heterogeneity and Future Direction of Major Adverse Kidney EventsThe "AKI/AKD/CKD axis" represents a critical continuum in nephrology, highlighting that acute kidney injury (AKI) is not merely a self-limiting episode but a potent driver of chronic kidney disease (CKD). Numerous clinical studies have reported the epidemiology of the AKI-to-CKD transition, demonstrating how recurrent or severe AKI accelerates renal decline. Crucially, methodological heterogeneity in defining Major Adverse Kidney Events (MAKE), as highlighted by our recent scoping review (Maeda et al., Intensive Care Med 2024), complicates the interpretation of clinical trial outcomes. To ensure the success of future clinical trials targeting AKI and the AKI-to-CKD transition, we must not only identify optimal therapeutic targets, but also establish standardized outcomes that directly align with improved patient care.Targeted Polymyxin B Hemadsorption in Sepsis: Lessons from Japanese Experience and Patient SelectionPolymyxin B haemadsorption (PMX-HA) has a long clinical history in Japan in the treatment of endotoxemia and septic shock. However, recent international randomized controlled trials and clinical guidelines have caused controversy regarding its routine use, citing inconsistent survival benefits in unselected populations. This presentation reviews the evolution of PMX-HA, from its origins in extensive Japanese clinical experience to modern precision medicine approaches in intensive care. Recent secondary analyses and real-world studies have highlighted significant heterogeneity in treatment effects, underscoring the necessity of appropriate patient selection. Subgroup analyses from the EUPHRATES trial demonstrated the potential efficacy of PMX-HA in patients with moderate-to-high endotoxin activity levels (EAA 0.6–0.9) and high severity of organ failure. Furthermore, machine learning applications such as causal forest modelling on large observational and trial cohorts have successfully identified specific biomarker profiles and clinical characteristics that define true responders.

• Social Determinants of Health and Acute Kidney Injury
  Rolando Claure-Del GranadoBolivia Speaker Practical Steps to Train (and Become) an AI-Era PhysicianArtificial intelligence is rapidly becoming part of everyday medicine, yet many physicians remain uncertain about how to begin using it effectively and responsibly. Becoming an “AI-era physician” does not require advanced technical expertise; it requires curiosity, critical thinking, and practical skills that can be progressively incorporated into clinical, academic, and research activities. In this Meet the Experts session, participants will explore concrete approaches to developing AI literacy, improving prompting skills, critically evaluating AI-generated information, and identifying useful applications in clinical reasoning, education, scientific writing, research, and workflow optimization. Through expert perspectives, real-world examples, and interactive discussion, the session will also address common pitfalls, including hallucinations, bias, privacy concerns, and overreliance on automation. The goal is to provide participants with a practical roadmap for moving from occasional AI use to confident, thoughtful, and responsible integration of AI into professional practice.Precision Solute Control and Dynamic Dosing with CRRTContinuous kidney replacement therapy (CRRT) is often prescribed using fixed effluent targets, yet critically ill patients have rapidly changing metabolic demands, solute loads, and treatment goals. Precision CRRT requires moving beyond a “one-dose-fits-all” approach toward dynamic prescription and real-time adjustment of therapy. In this interactive workshop, participants will learn how to individualize CRRT dose according to clinical objectives, solute kinetics, treatment interruptions, residual kidney function, and evolving metabolic needs. Practical case-based exercises will address clearance of urea and other small solutes, management of severe hyperkalemia and metabolic acidosis, control of sodium and other electrolyte disorders, and strategies for avoiding under- or overdosing. The workshop will also explore how modality, blood flow, dialysate and replacement-fluid rates, predilution, and delivered versus prescribed dose influence solute clearance. Participants will leave with a practical framework for adapting CRRT prescriptions dynamically and safely at the bedside.Social Determinants of Health and Acute Kidney InjuryAcute kidney injury (AKI) is not only a clinical syndrome but also a reflection of social and structural inequities that shape who becomes ill, who receives timely diagnosis, and who survives. Poverty, geography, education, access to clean water and sanitation, healthcare availability, occupational exposures, and delayed referral can all influence the risk, severity, and outcomes of AKI. These determinants are particularly relevant in low- and middle-income settings, where preventable causes of AKI remain common and access to laboratory testing, specialist care, and kidney replacement therapy may be limited. This plenary session will examine how social determinants interact with biological vulnerability and health-system capacity across the AKI continuum—from prevention and early recognition to treatment and recovery. Addressing AKI effectively therefore requires more than advances in diagnostics and therapeutics; it demands equitable health systems, stronger prevention strategies, and policies that reduce barriers to timely kidney care.

• Acute PD vs Acute HD: Which Is the Right Choice?
  Nattachai SrisawatThailand Speaker Precision Sepsis-AKI — Biomarkers, AI and Phenotyping in the Asia-PacificSepsis-associated AKI in the Asia-Pacific carries a burden that global datasets underrepresent. In the SEA-AKI prospective multicentre ICU study, AKI was very common, with stage 3 reaching 28.9%, and infectious disease among the independent risk factors for AKI development. In the InSEA-RRT registry — 2,315 critically ill patients with stage 3 AKI across 24 hospitals in Southeast Asia and India — 47% died during hospitalization, with major adverse kidney events tracked to two years. These cohorts expose the limits of treating sepsis-AKI as one disease. This lecture examines how damage and stress biomarkers, machine-learning models trained on regional rather than imported data, and sub-phenotyping by trajectory and host response can move us from a single creatinine-based label toward actionable patient groups. Emphasis will be on what is deployable in resource-variable settings, where biomarker access is uneven and registry infrastructure is often the practical starting point for precision medicine.Timing of DialysisWhen to start kidney replacement therapy (KRT) in AKI remains one of the most frequent bedside decisions in critical care, and the trial evidence has settled less than it first appears. ELAIN favoured early initiation, AKIKI and IDEAL-ICU did not, STARRT-AKI showed no survival benefit from an accelerated strategy with more dialysis dependence at 90 days, and AKIKI-2 found that delaying further offered no advantage and may cause harm. This session works through illustrative cases rather than trial summaries: the patient with rising creatinine but no urgent indication, refractory hyperkalaemia or acidosis demanding immediate treatment, the fluid-overloaded patient with worsening oxygenation, and the diuretic-responsive patient in whom watchful waiting proves correct. Each case is used to separate absolute indications from the discretionary zone where trials apply. Emphasis will be on practical decision aids — urine output trajectory, furosemide stress testing, fluid balance, and organ-support burden — and on when not starting is the better decision.Acute PD vs Acute HD: Which Is the Right Choice?For AKI requiring kidney replacement therapy outside well-resourced ICUs, the practical question is which modality can be started safely tonight. Acute peritoneal dialysis (PD) needs no vascular access, anticoagulation, water treatment, or machine, but concerns persist about clearance and ultrafiltration control. Our multicentre randomized trial assigned 157 patients with AKI to lower-dosage acute PD (18–24 L/day) or intermittent hemodialysis three times weekly. Sepsis caused 68% of AKI. Twenty-eight-day mortality was 50% versus 49% (risk difference 0.6%), meeting the prespecified noninferiority margin, with comparable dialysis-free survival and seven-day fluid balance. Complications diverged rather than favoured one modality: intradialytic hypotension was more frequent with hemodialysis, hypokalemia with PD. This lecture translates these findings into practice — where lower-dosage PD is a legitimate first choice, where it is not, how to prescribe and monitor it, and how modality availability shapes AKI preparedness in resource-limited settings.

• Extracorporeal Therapies in Trauma, Burns and Cerebral Edema
  John ProwleUnited Kingdom Speaker Trajectories of Critical Illness – Defining Endotypes from Routine DataCritical illness is a heterogeneous syndrome characterized by diverse clinical trajectories and variable responses to treatment. Defining biologically and clinically meaningful endotypes using routinely collected healthcare data offers an opportunity to improve risk stratification, prognostication, and personalized therapeutic strategies, enabling earlier intervention, enhanced clinical decision-making, and precision medicine in critical care. In particular the transition from acute to persistent critical illness represents a pivotal phase in intensive care, marked by a shift from the initial disease insult to prolonged organ dysfunction driven by complex host responses. Early identification of patients at risk of this transition remains a major clinical challenge and opportunity.Dynamic Prescription of CRRT Ready for Prime TimeContinuous renal replacement therapy (CRRT) has evolved from a standardized supportive therapy to a platform for precision critical care. Increasing evidence suggests that fixed prescriptions fail to accommodate the dynamic physiological changes encountered during critical illness, resulting in suboptimal solute clearance, fluid management, and metabolic control. Dynamic prescription integrates evolving haemodynamic status, fluid balance, acid–base homeostasis, electrolyte disturbances, and recovery trajectories to optimize therapy delivery while minimizing complications and treatment interruptions. This paradigm supports individualized kidney support rather than protocol-driven care. Emerging decision-support systems and data-driven algorithms have the potential to transform CRRT into a responsive, patient-centred intervention, improving kidney recovery, organ support, and outcomes in critically ill patients. Adapting CRRT for patients with Electrolyte and acid-base disordersContinuous renal replacement therapy (CRRT) is uniquely positioned to provide precise correction of complex electrolyte and acid–base disturbances in critically ill patients. Beyond kidney support, modern CRRT prescriptions can be individualized to account for the severity and evolution of dysnatremia, dyskalemia, calcium disorders, and metabolic acidosis or alkalosis. Customization of dialysate and replacement fluid composition, treatment dose, buffer delivery, and regional citrate anticoagulation enables controlled correction while minimizing the risks of metabolic complications. Dynamic prescription based on serial biochemical monitoring and changing clinical physiology can be embedded into treatment protocols, facilitating safe correction of sodium, potassium, calcium, and bicarbonate abnormalities while optimizing organ support and improving outcomes in critically ill patients. Extracorporeal Therapies in Trauma, Burns and Cerebral OedemaExtracorporeal therapies (ECTs) are an important adjunct in the management of critically ill patients with severe trauma, major burns, and brain injuries. Acute kidney injury, systemic inflammation, rhabdomyolysis, and profound fluid and electrolyte disturbances frequently complicate these conditions, necessitating timely organ support. Continuous kidney replacement therapy (CKRT) provides effective management of metabolic derangements while enabling precise fluid balance in hemodynamically unstable patients. In trauma and burns, ECTs may facilitate the clearance of myoglobin in severe rhabdomyolysis, support fluid management during resuscitation, and could enable removal of damage or pathogen associated molecular patterns mediating multiorgan failure. In patients with cerebral edema, CKRT offers gradual osmotic control and minimizes intracranial pressure fluctuations compared with intermittent dialysis, making it the preferred modality when kidney replacement therapy is required. We will review current evidence, practical considerations, and emerging extracorporeal strategies, highlighting their role in improving physiological stability and supporting recovery in critically ill patients.
