    S01E43 | EDTA for CVADs: Can a Line Lock Reduce ICU Catheter Complications?

    In this episode of PRISM Rounds, we discuss the JAMA 2026 randomized clinical trial by Ornowska and colleagues testing whether 4% tetrasodium EDTA, or t-EDTA, used as a locking fluid for inactive central venous access device lumens, can reduce CVAD-associated complications in adult ICU patients. This pragmatic, triple-blind, multicenter, cluster-randomized crossover trial included 1468 ICU patients across 6 Canadian hospitals. The primary composite outcome—CVAD-associated bloodstream infection, catheter occlusion requiring alteplase, or catheter removal due to occlusion—occurred at 13.1 vs 19.9 events per 1000 catheter-days with t-EDTA versus control. The main signal was fewer catheter occlusions requiring alteplase; infection and thrombosis events were uncommon and should not be overinterpreted.

    S01 Bonus Episode01: Prevent and Reverse Heart Disease — A Patient-Friendly Book Review

    In this PRISM Rounds bonus episode, we step away from our usual journal-club format for a patient-facing book review of Prevent and Reverse Heart Disease by Caldwell B. Esselstyn Jr., M.D. This book was published in 2007, and cardiovascular prevention guidelines have evolved since then. But its central message remains practical and motivating: patients are not powerless, and daily food choices can be an important part of reducing cardiovascular risk. This episode is designed especially for physicians and clinicians who want a simple, shareable way to start a food-focused heart-health conversation with patients. We focus on practical steps individuals can take: improving breakfast, building plant-forward meals, stocking healthier foods at home, and making small sustainable changes. Educational only. Not medical advice. Patients should discuss major diet or medication changes with their healthcare team.

    S01E42: Auto-Adjusted NIV in OHS - The Pickwick Titration Trial

    In this episode of PRISM Rounds, we discuss the AJRCCM 2026 Pickwick Titration Trial, which asked whether automatically adjusted noninvasive ventilation can match manually adjusted NIV titrated in the sleep lab for ambulatory patients with obesity hypoventilation syndrome. The trial found that auto-adjusted NIV produced similar 12-month improvement in daytime PaCO₂ compared with manually adjusted NIV, while reducing cost and potentially decreasing sleep-lab burden. The accompanying editorial highlights the real-world nuance: CPAP remains first-line for many stable OHS patients with severe OSA, but auto-adjusted NIV may be especially useful when NIV is indicated and access to in-lab titration is limited.

    S01E41: EIT-Guided PEEP in ARDS — Precision Ventilation or Too Much Titration?

    In this episode of PRISM Rounds, we discuss the 2026 AJRCCM EITVent randomized clinical trial and its accompanying editorial. The study asked whether electrical impedance tomography, or EIT, could help clinicians individualize PEEP in adults with moderate to severe ARDS compared with the traditional lower PEEP/FIO2 table. The overall trial was neutral: EIT-guided PEEP did not reduce 28-day mortality, ventilator-free days, length of stay, or major safety outcomes. But an important subgroup signal emerged in patients with higher lung recruitability, raising a practical bedside question: should EIT be used selectively to guide precision ventilation rather than as routine daily exhaustive PEEP titration? We discuss the trial design, the “collapse-overdistension crossing point,” the editorial’s caution about repeated recruitment maneuvers and decremental PEEP trials, and how this should influence bedside ventilator thinking in ARDS.

    S01E40 | Balanced Fluids vs Saline in Pediatric Septic Shock: Why Adult ICUs Should Care

    This week on PRISM Rounds, we discuss the April 2026 New England Journal of Medicine PRoMPT BOLUS trial comparing balanced crystalloids with 0.9% saline in children treated for suspected septic shock. The trial enrolled more than 9,000 children across 47 emergency departments and found no significant difference in major adverse kidney events between balanced fluid and saline. Balanced fluids reduced hyperchloremia and hypernatremia, but those biochemical advantages did not translate into better kidney outcomes, mortality, or hospital-free days. Although this is a pediatric trial, it is relevant for adult ICU and ED clinicians because it speaks to a familiar bedside question: when we reach for crystalloid early in sepsis, does fluid type meaningfully change patient-centered outcomes? We connect this trial to adult sepsis resuscitation, prior fluid-choice studies, and the broader lesson that “more physiologic” does not always mean “better outcomes.” Article: Balanced Fluid or 0.9% Saline in Children Treated for Septic Shock DOI: https://doi.org/10.1056/NEJMoa2601969Educational only; not medical advice.

    S01E39 | The FAST Trial - Rapid AST for Gram-Negative Bacteremia

    In this episode of PRISM Rounds, we review the JAMA FAST randomized clinical trial of rapid antimicrobial susceptibility testing for gram-negative bloodstream infections and the accompanying editorial, “Is FASTer Better?” The trial did not improve the primary DOOR outcome at 30 days, but rapid AST shortened antibiotic modification times and may be most useful when resistant organisms, septic shock, or ineffective empiric therapy are in play. We discuss why faster lab data alone may not improve mortality unless stewardship, drug availability, and bedside action close the loop. Educational only.

    S01E38 | Portable TB Testing — MiniDock MTB and Diagnostic Equity

    In this episode of PRISM Rounds, we review the NEJM study of MiniDock MTB, a portable near-point-of-care molecular test for pulmonary tuberculosis using sputum and tongue swabs. The study found that MiniDock MTB outperformed smear microscopy, approached Xpert Ultra performance with sputum swabs, and met WHO near-point-of-care diagnostic accuracy targets. We discuss why this matters for resource-limited settings, where delayed TB diagnosis, repeat visits, and limited access to molecular testing remain major barriers to care. We also cover the key limitations: lower sensitivity in paucibacillary disease, smear-negative TB, and people living with HIV, plus the need for reflex drug-resistance testing. Educational use only. AI-generated voices may include occasional mispronunciations.

    S01E37 | The HIT Trial: Is "Good Enough" Better for Hyponatremia Correction?

    Are we treating the monitor or the patient? This episode breaks down the HIT Trial (NEJM Evidence), where 2,173 patients with chronic hyponatremia were randomized to test if intensive sodium correction actually improves clinical outcomes. https://pubmed.ncbi.nlm.nih.gov/41733398/ The Results Lab Normalization: The targeted algorithm was highly effective at "fixing the number," reaching normal sodium levels in 60.4% of patients compared to 46.2% in standard care. Clinical Outcomes: Despite better labs, there was no reduction in 30-day mortality or rehospitalization (20.5% vs. 21.8%, p=0.45). Safety: While correction was more aggressive in the intervention group, zero cases of osmotic demyelination syndrome occurred. Bedside Takeaway Standard care is likely "good enough" for moderate hyponatremia in the short term. We discuss the "Good Enough" trap and why pushing for perfect laboratory values doesn't always translate to better patient-centered survival.
