Abstract Culture results in patients with septic shock affect their management strategies. Our study aimed to compare the clinical characteristics and outcomes of patients with culture-negative septic shock (CNSS) and culture-positive septic shock (CPSS). A single-center, retrospective, case-control study included adult patients diagnosed with septic shock in the emergency department between January 1, 2019 and March 31, 2020. They were divided into CNSS and CPSS groups based on their culture results. Patients with CPSS (63.7%, 311/488) and CNSS (36.3%, 177/488) were identified. The CPSS and CNSS groups had comparable clinical outcomes, including mechanical ventilation (29.6% vs. 32.8%, p = 0.46), renal replacement therapy (19.3% vs. 23.2%, p = 0.31), intensive care unit care (51.8% vs. 45.2%, p = 0.16), 30-day (35.7% vs. 36.7%, p = 0.82) and in-hospital mortality (39.5% vs. 41.8%, p = 0.63). The duration (13 [8−19] vs. 16 [10−23], days, p = 0.04) and de-escalation timing (5 [2−10] vs. 9 [7−12], day, p = 0.02) of antibiotic administration in the CNSS group was significantly shorter and earlier than in the CPSS group. Patients with CNSS and CPSS had similar clinical characteristics and adverse outcome proportions. Physicians can evaluate the feasibility of early de-escalation or discontinuation of antibiotic administration in CNSS patients with clinical improvement.

Sepsis accounts for approximately one in three hospital deaths, and is associated with very high health care costs due to prolonged lengths of stay in the intensive care unit and hospital. Sepsis is essentially an immunologic response to infection that is propagated systemically, leading to diffuse cellular and microcirculatory dysfunction, vasodilation, vital organ hypoperfusion, and eventual failure. This review covers the pathophysiology, stabilization/assessment, diagnosis, treatment, and disposition and outcomes of sepsis. Figures show the inflammatory and thrombotic response to infection, the action of nitric oxide on vascular smooth muscle cells, accelerated glycolysis and increased lactate production as a result of the catecholamine surge seen in septic shock, sepsis mortality associated with number of organ failures identified in the emergency department (ED), and protocolized therapy for septic shock. Tables list definitions of sepsis syndromes; frequently cited scoring systems for mortality prediction in emergency department patients with sepsis; Sequential Organ Failure Assessment (SOFA) score; current recommendations regarding treatment bundles at 3 and 6 hours of resuscitation; antibiotic recommendations based on suspected source; and vasopressors used in septic shock with recommended dosing, mechanism of action, and indications. This review contains 5 figures, 7 tables, and 57 references.

Abstract Background We evaluated the characteristics and outcomes of culture-negative septic shock versus culture-positive septic shock.Methods We performed a retrospective observational study of data from a prospective registry from 2014 to 2018. A total of 2,499 adult patients with septic shock were enrolled. The primary outcome was 90-day mortality, and the secondary outcomes were the length of hospital stay, a requirement for mechanical ventilation or renal replacement therapy, and in-hospital mortality.Results Of 1,718 patients with septic shock, 1,012 (58.9%) patients were culture-positive (blood 803, urine 302, sputum 102, others 204) and the median pathogen detection time was 9.5 hours (aerobic 10.2 hours and anaerobic 9.0 hours). The most common site of infection among the culture-positive was the hepatobiliary tract (39.5%), while for the culture-negative was the lower respiratory tract (38.2%). The culture-negative group had a lower mean body temperature (37.3 vs 37.7 ℃), lactate (2.5 vs. 3.2 mmol/L), C-reactive protein (11.1 vs 11.9 mg/dL), and sequential organ failure assessment score (7.0 vs. 8.0) than that of the culture-positive group. However, 90-day mortality between the groups was not significantly different (32.7 vs 32.2%, p = 0.83), and the other clinical outcomes also did not differ significantly. Moreover, a shorter culture detection time was correlated with a higher sequential organ failure assessment score but not with mortality.Conclusion Patients with septic shock are frequently culture-negative, especially in cases where the infection focus is in the lower respiratory tract. Although culture-negative was associated with degree of organ dysfunction, it was not an independent predictor of death.

Abstract Purpose To compare the mortality rates between culture-positive and culture-negative sepsis in complicated intra-abdominal infections (cIAI) and investigate the predictors of culture-positivity and their causative microorganisms. Materials and methods The medical records of 1581 adult patients who underwent emergency gastrointestinal surgery between January 2013 and December 2018 were reviewed retrospectively. A total of 239 patients with sepsis or septic shock who were admitted to an emergency department, underwent emergency surgery for cIAI, and needed postoperative intensive care unit care were included and divided into two groups according to their initial blood and peritoneal culture results. Results Among the 239 patients, 200 were culture-negative and 39 were culture-positive. The culture-positive group had higher in-hospital (35.9% vs 14.5%; P = .001) and 30-day mortality (30.8% vs 12.0%; P = .003) than the culture-negative group. Colon involvement (OR 4.211; 95% CI 1.909–9.287; P < .001) and higher Sequential Organ Failure Assessment (SOFA) score (OR 1.169; 95% CI 1.065–1.282; P = .001) were shown to be the predictors of culture-positive sepsis for cIAI. Regarding antibiotic sensitivity, 31.6% of the gram-positive bacteria were methicillin-resistant and 42.1% of the gram-negative bacteria were extended spectrum β-lactamase-producing Enterobacteriaceae. Conclusions Patients with cIAI had higher mortality rates in culture-positive sepsis than in culture-negative sepsis. High SOFA score and colon involvement were the risk factors associated with culture-positivity. The most common single species grown in the blood or peritoneal cultures was Escherichia coli, and the most common group was Gram-positive cocci.
