Background: Sepsis bundles can decrease mortality in patients with severe sepsis or septic shock. However, current methods of measuring pressure, such as central venous pressure, are inadequate. This study investigated the effect of improved sepsis bundles informed by pulse-indicated continuous cardiac output.
Methods: We compared the outcome of treatment with sepsis bundles informed by either conventional pressure measurements or pulse-indicated continuous cardiac output. Patients in 2 groups received fluid resuscitation, standard antibiotics, and oxygen therapy.
Results: A total of 105 patients with septic shock were randomly divided into 2 groups: the conventional sepsis bundle group (n = 52) or the improved sepsis bundle group (ISBG, n =53). The ISBG significantly reduced the mean Acute Physiology and Chronic Health Evaluation II and Sepsis-related Organ Failure Assessment scores. Significantly fewer ISBG-treated patients received vasoactive drugs compared to conventional sepsis bundle group-treated patients. In addition, patients in the ISBG exhibited a significantly increased arterial blood lactate clearance rate and required less total fluid resuscitation and a shorter duration of mechanical ventilation and stay in the intensive care unit.
Conclusions: Pulse-indicated continuous cardiac output-directed sepsis bundles can reduce the severity of septic shock, provide more accurate fluid resuscitation, and reduce the duration of mechanical ventilation and stay in the intensive care unit.

Evaluating the Adequacy of Central Line-Associated Bloodstream Infection As a Quality Measure: A Cross-Sectional Analysis at a Single Tertiary Care Center.

Department of Infectious Disease, Cleveland Clinic, Cleveland, OH.
Importance: The current definition of central line-associated bloodstream infection (CLABSI) may overestimate the true incidence of CLABSI as it is often unclear whether the bloodstream infection (BSI) is secondary to the central line or due to another infectious source.
Objectives: We aimed to assess the prevalence and outcomes of central CLABSI at our institution, to identify opportunities for improvement, appropriately direct efforts for infection reduction, and identify gaps in the CLABSI definition and its application as a quality measure.
Design Setting And Participants: Retrospective cross-sectional study of patients identified to have a CLABSI in the period 2018-2022 cared for at the value-based purchasing (VBP) units of a 1200-bed tertiary care hospital located in Cleveland, OH.

Background And Aims: Alcohol-associated hepatitis (AH) frequently triggers acute decompensation (AD) in cirrhosis, with severe AH linked to high short-term mortality, especially in acute-on-chronic liver failure. Current corticosteroid treatments have limited efficacy, highlighting the need for new therapies. We hypothesized that severe AH outcomes are influenced by early specialized care; thus, we examined the impact of time-to-tertiary care (TTTc).

Background: Although multifaceted control intervention actions (bundles) are highly effective in reducing the risk of device-related healthcare-associated infections (d-HAIs), no studies have explored their impact on the outcomes of kidney transplant recipients (KTRs) or the extent of risk reduction achievable through the bundle implementation.
Methods: Seven hundred ninety-eight prevalent KTRs admitted to the intensive care unit (ICU) requiring invasive devices were included: 449 patients from the bundle preimplementation period and 349 from the postimplementation period. The primary outcome was mortality within 90 d of ICU admission.
Longer Total Interhospital Transfer Times for Rural Sepsis Patients Not Associated with Increased Mortality.

Department of Emergency Medicine, University of Iowa Carver College of Medicine, Iowa City, Iowa.
Objectives: Sepsis is a time-sensitive condition, and many rural emergency department (ED) sepsis patients are transferred to tertiary hospitals. The objective of this study was to determine whether longer transport times during interhospital transfer are associated with higher sepsis mortality or increased hospital length-of-stay (LOS).
Methods: A cohort of rural adult (age ≥ 18 y) sepsis patients transferred between hospitals were identified in the TELEmedicine as a Virtual Intervention for Sepsis Care in Emergency Departments (TELEVISED) parent study.

Article Synopsis
- The study investigates the effect of early antibiotic administration on 28-day in-hospital mortality in patients with suspected sepsis in the emergency department.
- Among 872 participants, those who received antibiotics within an hour had a significantly lower mortality rate (9.6%) compared to those who received them later (14.7%).
- Delays in antibiotic treatment were linked to increased mortality risk, with an adjusted odds ratio of 2.00 for those who received antibiotics after one hour and a 1.06 increase in risk for each additional hour of delay.
