1. Steroid administration, timing, and dose in patients with septic shock in the emergency department: retrospective analysis of a multicenter prospective cohort study.
In a 5,127-patient ED-based cohort with septic shock, steroid use—particularly hydrocortisone—was associated with lower 28-day mortality after adjustment. Earlier initiation relative to vasopressor start and avoidance of high daily doses (>300 mg/day) were linked to better outcomes; benefits were pronounced in patients also receiving vasopressin.
Impact: This large, practice-proximal analysis addresses when and how much hydrocortisone to give in the ED—an actionable gap not well covered by ICU-centric RCTs—and provides dose–timing signals to inform protocols.
Clinical Implications: Consider early hydrocortisone initiation in vasopressor-dependent septic shock patients in the ED, avoid daily doses >300 mg, and prioritize earlier timing relative to vasopressor start—especially when vasopressin is required. Findings are hypothesis-generating and should complement, not replace, guideline-directed care.
Key Findings
- Steroid administration was associated with lower 28-day mortality (hydrocortisone aOR 0.745, 95% CI 0.627-0.884).
- Benefit was evident in the vasopressin subgroup (aOR 0.631, 95% CI 0.494-0.805) but not without vasopressin.
- Longer delay from first vasopressor to first hydrocortisone increased mortality (aOR 1.018 per minute), and doses >300 mg/day were associated with harm (aOR 1.577).
Methodological Strengths
- Large multicenter cohort with robust adjustments (PSM, IPTW, multivariable and time-dependent Cox models).
- Clinically relevant ED setting capturing early treatment decisions.
Limitations
- Observational design cannot exclude residual confounding and indication bias.
- Practice patterns and vasopressin use may limit generalizability across systems.
Future Directions: Prospective, randomized trials stratifying by vasopressor profile and testing early, protocolized hydrocortisone dosing (avoiding >300 mg/day) in the ED are warranted.
The benefit and optimal timing of corticosteroids in septic shock remain debated. Most evidence comes from intensive care unit-based studies, although key treatment decisions are often made early in the emergency department (ED). This study evaluated the association between steroid administration, including hydrocortisone timing and dose, and mortality in patients with septic shock in the ED. This retrospective observational study used an ED-based prospective multicenter septic shock registry from the Korean Shock Society (KoSS). The association between ster
2. Integrated epidemiologic investigation and genomic confirmation of a Klebsiella pneumoniae neonatal sepsis outbreak in Botswana.
During a 12-month neonatal unit surveillance, investigators identified 55 K. pneumoniae bloodstream infections and a median 28% MDR-Kpn colonization prevalence. WGS linked >50% of BSI genomes to an ST1414 clone also recovered from multi-use IV fluid bags; instituting a 24-hour discard policy controlled the outbreak. Notably, the outbreak clone was cephalosporin-susceptible and therefore missed by MDR-only colonization screening.
Impact: This study demonstrates real-time genomic epidemiology directly informing a simple, high-impact IPC intervention (IV medication discard policy) that halted a lethal neonatal sepsis outbreak.
Clinical Implications: Neonatal units should consider integrated WGS with systematic epidemiologic tracing during suspected outbreaks and review IV medication handling policies; colonization surveillance focused solely on MDR organisms may miss outbreak-prone susceptible clones.
Key Findings
- Identified 55 K. pneumoniae BSIs and median MDR-Kpn colonization prevalence of 28% during 12 months.
- WGS linked >50% of BSI isolates and all six IV fluid isolates to ST1414 with <25 SNPs, implicating multi-use IV bags.
- Implementing a 24-hour discard policy for IV medications controlled an outbreak (41 BSIs, 10 deaths).
- The outbreak clone was cephalosporin-susceptible, escaping MDR-focused colonization screening.
Methodological Strengths
- Integration of prospective surveillance, environmental sampling, and WGS with high-resolution SNP analysis and Bayesian phylogenetics.
- Actionable IPC response implemented and linked temporally to outbreak control.
Limitations
- Single-center neonatal unit limits generalizability; not all clinical isolates were sequenced.
- Colonization surveillance biased toward MDR organisms may underestimate susceptible outbreak strains.
Future Directions: Expand integrated WGS-enabled IPC networks in LMIC neonatal units, and develop risk-based colonization surveillance that includes high-risk susceptible clones.
Klebsiella pneumoniae (Kpn) is a major cause of infant mortality worldwide, with most transmission occurring among hospitalized neonates in low- and middle-income countries where infections caused by multidrug-resistant Kpn (MDR-Kpn) are increasingly common. We hypothesized that integrating laboratory surveillance for neonatal colonization and infection, real-time epidemiologic investigations, and whole-genome sequencing (WGS) could identify transmission pathways to guide targeted infection prevention and control (IPC) strategies. We conducted Kpn surveil
3. The prognostic value of red cell distribution width-to-albumin ratio for 28-day mortality in sepsis patients: a multicenter analysis based on the eICU Collaborative Research Database.
Among 13,888 eICU sepsis patients, higher admission RAR was independently associated with increased 28-day and in-hospital mortality. Patients above the median RAR (5.9) had a 28-day mortality of 23.0% versus 9.9% below median; restricted cubic splines supported a nonlinear association.
Impact: RAR is a low-cost, readily available composite biomarker that can be implemented immediately for sepsis risk stratification at admission.
Clinical Implications: Incorporate RAR into initial sepsis assessment to flag high-risk patients for closer monitoring, early escalation, and potential resource prioritization, while awaiting prospective validation.
Key Findings
- High-RAR group (≥ median 5.9) had a 28-day mortality of 23.0% vs 9.9% in low-RAR.
- Admission RAR was independently associated with 28-day and in-hospital mortality in multivariable Cox models.
- Restricted cubic spline analysis confirmed a nonlinear association between RAR and mortality.
Methodological Strengths
- Large multicenter dataset (eICU) with robust time-to-event modeling.
- Use of restricted cubic splines to explore nonlinearity and subgroup analyses.
Limitations
- Retrospective design subject to residual confounding; RAR thresholds may vary across laboratories.
- External prospective validation and cost-effectiveness analyses are pending.
Future Directions: Prospective validation across diverse settings, define actionable RAR thresholds, and test RAR-guided triage/escalation pathways.
BACKGROUND: Sepsis remains one of the leading causes of death in intensive care units worldwide. The red blood cell distribution width-to-albumin ratio (RAR) is calculated by dividing the red blood cell distribution width (%) by serum albumin (g/dl); this indicator combines information on inflammation and nutritional status and is closely associated with the prognosis of critically ill patients. This study aimed to explore the association between RAR and 28-day all-cause mortality in adult patients with sepsis. METHODS: This retrospective, multi
