The Society of Critical Care Medicine (SCCM) and the American College of Emergency Physicians (ACEP) acknowledge concerns expressed about the recently released Surviving Sepsis Campaign (SSC) Hour-1 Bundle and the appropriateness of implementation in the United States. Both organizations understand the importance of prompt and optimal sepsis diagnostics and treatment. SCCM and ACEP along with other involved international experts are organizing a meeting as soon as possible to carefully review the recommendations, and provide guidance on bundle implementation and care of potentially septic patients who present to emergency departments in the United States. We recommend that hospitals not implement the Hour-1 bundle in its present form in the United States at this time.
