Endoscopy within 6 hours for non-variceal upper GI bleeding did not beat endoscopy within 24
A meta-analysis of 10,785 patients finds no mortality or rebleeding benefit from ultra-early endoscopy; one in five septic shock patients meets new refractory criteria, with 64% mortality; and AI sepsis models look better on paper than they have yet proved at the bedside.
The edition in brief
A meta-analysis of nine studies (10,785 adults) with non-variceal upper gastrointestinal bleeding found endoscopy within 6 hours did not reduce mortality (OR 0.88, 0.58 to 1.34) or rebleeding (OR 1.23, 0.90 to 1.67) compared with later endoscopy, including in high-risk patients, but was linked to more ICU admission. In a US health system cohort of 15,732 patients with septic shock (published June 2026), 21.8% met consensus criteria for refractory septic shock, noradrenaline equivalent above 0.5 µg/kg/min with lactate above 2 mmol/L; their hospital mortality was 64.4%, with risk-adjusted odds 4.87 times higher. A meta-analysis of 34 mostly retrospective studies of AI sepsis prediction reported a pooled AUROC of 0.913 but a prediction interval of 0.66 to 0.98, with heavy reuse of the same public datasets. In a Dutch cohort of 18,798 ED-to-ICU admissions, longer transfer time was associated with higher mortality after cardiac arrest in academic hospitals and the reverse in non-academic teaching hospitals, with no association in sepsis, pneumonia or overdose.
One in five with septic shock met refractory criteria, and nearly two in three of them died
Noradrenaline above 0.5 µg/kg/min with lactate above 2 meets the consensus criteria for refractory septic shock and marks high mortality: review adjuncts and source control, and talk to the family.
AI sepsis models score well in their own datasets but have little prospective proof
Treat AI sepsis alerts as unproven until validated locally; keep using clinical early warning scores.
Longer ED-to-ICU transfer was linked to death after cardiac arrest in academic hospitals only
Transfer time alone was not consistently linked to death, but after cardiac arrest avoidable delay should still be cut.
Score the upper GI bleed before you call the endoscopist
Use the Glasgow-Blatchford score to decide who needs admission, and resuscitate before worrying about endoscopy timing.
Ultra-early endoscopy did not reduce death or rebleeding in non-variceal upper GI bleeding
In non-variceal upper GI bleeding, resuscitate well and scope within 24 hours; racing to scope within 6 hours has not improved outcomes.
