Antibiotic Order-to-Infusion Time for Patients With Septic Shock: A Potential New Quality Metric*

Pharmacist Involvement in Sepsis Response and Time to Antibiotics: A Systematic Review

Introduction

Sepsis is a life-threatening medical emergency and a leading cause of morbidity and mortality worldwide. Reductions in time to antibiotics in patients presenting with sepsis or septic shock are associated with reduced mortality, and Surviving Sepsis Campaign guidelines recommend antibiotics within one hour of recognition. Pharmacists are well-equipped to help navigate the therapeutic and operational challenges associated with achieving this goal.

Objectives

To assess the association of pharmacist involvement in sepsis response with time to antibiotics in hospitalized patients with sepsis and septic shock.

Methods

A systematic review of the following databases was conducted: PubMed/MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Web of Science. Studies must have included a designated role of an individual pharmacist in the management of sepsis or septic shock and not be considered an operational change. The primary outcome of interest was time to antibiotic administration, with secondary outcomes including intensive care unit (ICU) and hospital length of stay as well as in-hospital mortality.

Results

We identified 10 studies including 1772 patients with sepsis or septic shock that evaluated a sepsis response in which a pharmacist was included. Studies included patients in the ICU, emergency department, and hospital ward setting. Seven studies demonstrated a significant reduction in time to antibiotics, with two other studies supporting this conclusion in extrapolation or sensitivity analysis. There was not a consistent reduction in ICU or hospital length of stay nor in-hospital mortality between those interventions involving a pharmacist compared with their defined control groups.

Conclusion

Pharmacist involvement in sepsis response, often as part of a multi-professional team-based approach to sepsis care, is associated with a reduced time to antibiotic administration for hospitalized patients with sepsis or septic shock.

Infectious Diseases Society of America Position Paper: Recommended Revisions to the National Severe Sepsis and Septic Shock Early Management Bundle (SEP-1) Sepsis Quality Measure

The Centers for Medicare & Medicaid Services' Severe Sepsis and Septic Shock Early Management Bundle (SEP-1) measure has appropriately established sepsis as a national priority. However, the Infectious Diseases Society of America (IDSA and five additional endorsing societies) is concerned about SEP-1's potential to drive antibiotic overuse because it does not account for the high rate of sepsis overdiagnosis and encourages aggressive antibiotics for all patients with possible sepsis, regardless of the certainty of diagnosis or severity of illness. IDSA is also concerned that SEP-1's complex "time zero" definition is not evidence-based and is prone to inter-observer variation. In this position paper, IDSA outlines several recommendations aimed at reducing the risk of unintended consequences of SEP-1 while maintaining focus on its evidence-based elements. IDSA's core recommendation is to limit SEP-1 to septic shock, for which the evidence supporting the benefit of immediate antibiotics is greatest. Prompt empiric antibiotics are often appropriate for suspected sepsis without shock, but IDSA believes there is too much heterogeneity and difficulty defining this population, uncertainty about the presence of infection, and insufficient data on the necessity of immediate antibiotics to support a mandatory treatment standard for all patients in this category. IDSA believes guidance on managing possible sepsis without shock is more appropriate for guidelines that can delineate the strengths and limitations of supporting evidence and allow clinicians discretion in applying specific recommendations to individual patients. Removing sepsis without shock from SEP-1 will mitigate the risk of unnecessary antibiotic prescribing for noninfectious syndromes, simplify data abstraction, increase measure reliability, and focus attention on the population most likely to benefit from immediate empiric broad-spectrum antibiotics.

Considerations for Empiric Antimicrobial Therapy in Sepsis and Septic Shock in an Era of Antimicrobial Resistance

Patients with sepsis present across a spectrum of infection sites and severity of illnesses requiring complex decision making at the bedside as to when prompt antibiotics are indicated and which regimen is warranted. Many hemodynamically stable patients with sepsis and low acuity of illness may benefit from further work up before initiating therapy, whereas patients with septic shock warrant emergent broad-spectrum antibiotics. The precise empiric regimen is determined by assessing patient and epidemiological risk factors, likely source of infection based on presenting signs and symptoms, and severity of illness. Hospitals should implement quality improvement measures to aid in the rapid and accurate diagnosis of septic patients and to ensure antibiotics are given to patients in an expedited fashion after antibiotic order.
