Hour-1 Bundle Updated


The Surviving Sepsis Campaign has updated the Hour-1 bundle emphasizing time of recognition and element completion guidance.

The Hour-1 bundle* should be viewed as a quality improvement opportunity moving toward an ideal state. For critically ill patients with sepsis or septic shock, time is of the essence. Although the starting time for the Hour-1 bundle is recognition of sepsis, both sepsis and septic shock should be viewed as medical emergencies requiring rapid diagnosis and immediate intervention. 

The Hour-1 bundle encourages clinicians to act as quickly as possible to obtain blood cultures, administer broad spectrum antibiotics, start appropriate fluid resuscitation, measure lactate, and begin vasopressors if clinically indicated. Ideally these interventions would all begin in the first hour from sepsis recognition but may not necessarily be completed in the first hour. Minimizing the time to treatment acknowledges the urgency that exists for patients with sepsis and septic shock. 

*Note the description of the Hour-1 Bundle above is the most current having passed all approval points effective 1/10/19.

Surviving Sepsis Campaign Hour-1 Bundle of Care Elements:

  • Measure lactate level* 
  • Obtain blood cultures before administering antibiotics.
  • Administer broad-spectrum antibiotics.
  • Begin rapid administration of 30mL/kg crystalloid for hypotension or lactate level ≥ 4 mmol/L.
  • Apply vasopressors if hypotensive during or after fluid resuscitation to maintain MAP ≥ 65 mm Hg.
* Remeasure lactate if initial lactate is elevated (> 2 mmol/L)/
