Development and implementation of sepsis alert systems is challenging, particularly outside the monitored intensive care unit (ICU) setting. Barriers to wider use of sepsis alerts include evolving clinical definitions of sepsis, information overload, and alert fatigue, due to suboptimal alert performance. ⋯ Current evidence does not support routine use of sepsis alert systems in clinical practice. Continuous improvement in the afferent and efferent aspects will help translate theoretic advantages into measurable patient benefit.

ReviewEarly Identification and Treatment of Pathogens in Sepsis: Molecular Diagnostics and Antibiotic Choice.
Sepsis and septic shock are serious conditions associated with high morbidity and mortality. Rapid molecular methods for detection of microorganisms and antimicrobial resistance genes from positive blood cultures or whole blood have evolved over the past 10 years. ⋯ This article discusses the usefulness of current molecular test methods for the diagnosis of sepsis and their potential to enhance the success of antimicrobial stewardship programs. Clinicians and laboratories alike must appreciate key factors influencing the appropriate use and potential impact of these methods.

Clinicians have greatly improved care for septic shock. Urgent resuscitation using intravenous fluids and vasopressors as well as rapid administration of broad spectrum antibiotics are probably the most basic and universally accepted interventions. ⋯ Patients who have a poor response to resuscitation and patients with known severe ventricular dysfunction might merit advanced hemodynamic monitoring. This review examines important vasopressor and septic shock trials.

Sepsis is a common and life-threatening inflammatory response to severe infection treated with antibiotics and fluid resuscitation. Despite the central role of intravenous fluid in sepsis management, fundamental questions regarding which fluid and in what amount remain unanswered. Recent advances in understanding the physiologic response to fluid administration, and large clinical studies examining resuscitation strategies, fluid balance after resuscitation, colloid versus crystalloid solutions, and high- versus low-chloride crystalloids, inform the current approach to sepsis fluid management and suggest areas for future research.

Comment ReviewGoal-Directed Resuscitation in Septic Shock: A Critical Analysis.
The Early Goal-Directed Therapy versus Standard Care for Sepsis trial by Rivers and colleagues in 2001 suggested that a significant mortality reduction may be realized through goal-directed interventions early in the care of patients with septic shock. However, the recent publication of the Protocol-Based Care for Early Septic Shock (ProCESS), Australasian Resuscitation in Sepsis Evaluation (ARISE), and Protocolised Management in Sepsis (ProMISE) trials did not demonstrate the superiority of early goal-directed therapy over usual care. If usual care includes timely and meticulous care, a protocol may not be needed to realize the continued lowering mortality rates.
