Sepsis, September 28 edition

Using county-year data from Texas between 2006 and 2019, this study applied two complementary difference-in-differences designs to evaluate rural hospital closures. Closure exposure was associated with 11.52 to 11.60 additional annual deaths per 100,000 residents from time-sensitive conditions, representing a 5.4% increase from baseline mortality. Associations were concentrated in acute emergencies and were robust to several sensitivity analyses.

Impact: The study moves beyond individual clinical management to demonstrate a population-level relationship between loss of rural emergency infrastructure and mortality from time-sensitive diseases, including sepsis. Its quasi-experimental design strengthens the policy relevance of the findings.

Clinical Implications: Sepsis systems should incorporate regional access, transport times, referral capacity, and post-closure emergency coverage into preparedness planning. Maintaining or replacing rural emergency capacity may be important for reducing delays in time-sensitive treatment.

Future Directions: Future studies should link individual emergency medical service, transfer, treatment-timing, and mortality data to identify causal pathways, and should evaluate telemedicine, mobile critical-care transport, and regionalized sepsis networks as mitigation strategies.

In 29,647 adults with community-onset presumed bacterial sepsis across 67 hospitals, presenting symptoms were independently associated with antibiotic timing. Gastrointestinal symptoms were associated with lower odds of timely antibiotics, whereas prehospital fever was associated with higher odds. After adjustment for presenting symptoms, timely antibiotics were associated with a 2.10-percentage-point lower adjusted absolute 30-day mortality.

Impact: This study identifies clinically less obvious presentations, particularly gastrointestinal symptoms, as potential sources of antibiotic delay and demonstrates that the association between timely treatment and lower mortality persists after symptom adjustment. The findings directly inform sepsis-screening and emergency workflow design.

Clinical Implications: Hospitals should consider symptom-inclusive sepsis screening and targeted alerting for patients with gastrointestinal or otherwise nonspecific presentations. Earlier antibiotics remain important, but implementation should be paired with diagnostic stewardship to reduce treatment of noninfectious mimics.

Future Directions: Prospective implementation studies should test symptom-inclusive screening pathways, measure antibiotic appropriateness as well as timing, and evaluate whether targeted interventions reduce delays without increasing unnecessary antibiotic exposure.

This systematic review and meta-analysis included 10 randomized controlled trials with 1,011 patients comparing personalized with fixed-volume fluid resuscitation in sepsis. Across eight trials involving 901 patients, personalized resuscitation was associated with lower 30-day mortality (odds ratio 0.62, 95% CI 0.42-0.93). No significant differences were found for renal replacement therapy, mechanical ventilation, vasopressor duration, or hospital and intensive care unit length of stay.

Impact: The analysis challenges one-size-fits-all fluid administration by synthesizing randomized evidence in favor of physiologically guided resuscitation. It is clinically important because fluid overload and inadequate resuscitation both contribute to harm in septic shock.

Clinical Implications: Initial fluid therapy may be better guided by dynamic hemodynamic assessment, perfusion markers, and individual patient tolerance rather than by a uniform volume target. The findings support cautious adoption in experienced critical-care settings while awaiting larger, high-certainty trials.

Future Directions: Large multicenter randomized trials should compare standardized personalized algorithms, define treatment-responsiveness criteria, and assess fluid overload, renal outcomes, organ support, and patient-centered long-term outcomes.
