Abstract: Different Sepsis Scores, Same Signal: Simpler Tools Hold Up in a Resource-limited Pediatric ICUThree pediatric sepsis scores-Pediatric Sequential Organ Failure Assessment (pSOFA), Pediatric Logistic Organ Dysfunction (PELOD)-2, and Phoenix-predict mortality similarly well in a Bangladeshi ICU cohort, despite major data and resource constraints.We have largely assumed that organ dysfunction scores derived in high-income ICUs transfer poorly to low-and middle-income country (LMIC) settings.This dataset pushes back: discrimination holds up, even in a cohort dominated by infants with diarrheal disease and limited laboratory infrastructure.The real differentiator here is not accuracy-it's feasibility at the bedside.This is a secondary analysis of a prospective ICU cohort in Dhaka (96 children, median age 8 months, 23% mortality).All scores were calculated at admission; missing data were handled pragmatically ("carry-back" imputation), and Phoenix was computed without key coagulation labs.No external validation cohort, but adjustment for malnutrition and maternal education strengthens internal credibility.No declared conflicts; parent study NIH-funded.Discrimination clustered tightly: Area under the curve (AUC) 0.83 for pSOFA, 0.82 for PELOD-2, 0.79 for Phoenix.Mortality rose from 9.4% to 50% when pSOFA crossed >6 (absolute +40.6%), and from 8.2% to 48.6% when PELOD-2 exceeded >3 (absolute +40.4%)roughly one additional death per ~2-3 high-risk children identified.Phoenix-defined septic shock carried 43.5% mortality vs 16.4% otherwise (+27.1% absolute).The key limitation is case mix: 98% had diarrheal illness, so this is closer to "enteric sepsis physiology" than generalizable pediatric sepsis.The Phoenix score comes from the same broader research ecosystem; this reads as early external validation, not independence.Mechanistically, it's notable that simpler variables (SpO₂-based pSOFA, limited Phoenix inputs) retained signal despite missing labs-suggesting physiologic derangement dominates over biochemical granularity here.What I'd want next is whether these scores change decisions-transfer, fluids, vasopressors-not just predict outcomes.For now, in resource-limited ICUs, pSOFA or Phoenix looks sufficient-and simpler may be the real advantage.
