The Implementation Gap in Early Septic Shock Resuscitation: A Three-Barrier Framework.

Area of Science:

• Emergency Medicine
• Critical Care Medicine
• Health Systems Science

Background:

• The physiological rationale for early vasopressor use in septic shock is well-established through extensive research.
• Despite strong evidence, timely administration of norepinephrine within the first hour of recognition remains inconsistent in many healthcare settings.

Purpose of the Study:

• To reframe the challenge of early vasopressor delivery in septic shock from a clinical evidence issue to an implementation science problem.
• To identify and analyze key structural barriers hindering timely vasopressor administration.

Main Methods:

• Review of existing literature and analysis of implementation barriers.
• Identification of three primary structural barriers: regulatory (SEP-1 measure), cultural (workflow and practice scope), and upstream (time to recognition).
• Proposal of a parallel resuscitation framework with protocolized triggers.

Main Results:

• The SEP-1 quality measure inadvertently incentivizes a fluids-first approach, despite physician exceptions.
• A significant gap exists between policies allowing peripheral vasopressor use and the necessary operational infrastructure for bedside administration.
• Delays in vasopressor initiation are often downstream from delays in initial patient recognition.

Conclusions:

• Addressing early vasopressor delivery requires moving beyond physiological arguments to focus on operational and implementation challenges.
• Rebuilding the healthcare system's operational architecture, including protocolized triggers and stratified implementation strategies, is crucial for improving septic shock resuscitation.
