Sepsis Decision Aid

In the U.S., the treatment of sepsis and septic shock is complicated by strict regulations used to measure hospital sepsis outcomes. The Center for Medicare & Medicaid Services (CMS) Sep-1 guidelines are complex and based on chart abstraction. These factors lead to confusion and difficulty in the real-time treatment of patients. This decision aid is meant to assist in the regulatory steps for the treatment of a patient with sepsis. It is important to be aware that CMS makes changes to these criteria on a quarterly basis. This tool will be updated as often as possible to maintain correctness.

Does the patient have sepsis?

CMS does not use Sepsis-3 criteria for the SEP-1 Hospital Core Measure, however many private insurers and CMS utilize the Sepsis-3 criteria for reimbursement. Therefore, both criteria are listed here. Some hospitals utilize a hybrid method screening with SEP-1 criteria in the ED and utilizing Sepsis-3 criteria in the inpatient setting.

CMS SEP-1 Core Measure Definition Of Sepsis

Requires a source of infection AND > 2 SIRS criteria

SIRS Criteria

• Temp >100.9 or <96.8
• HR >90
• RR >20
• WBC >12k or <4k or >10% bands

---

Sepsis-3 Definition Of Sepsis

Requires a source of infection AND organ dysfunction (see qSOFA or SOFA below). Use statement: “Sepsis due to [infection] with acute sepsis-related organ dysfunction as evidenced by [specify organ dysfunction].”

qSOFA > 2

• Respiratory rate of > 22/min
• Altered Mental Status
• Systolic blood pressure < 100 mm Hg

SOFA > 2

Three Hour Bundle (Items to be completed within 3 hrs)

• Administer Broad Spectrum Antibiotics
  • Do not delay broad spectrum abx while searching for source
• Obtain Blood Cultures x 2
  • If unable to obtain 2 blood cultures, document inability to do so
• Obtain initial lactic acid

If MAP<65 (SBP<90) –OR– Lactic Acid >4 mmol/L

Administer 30 ml/kg IVF bolus

• If 30 mL/kg not given both must be done
  1. Order a specific amount of IVF – either specific volume (i.e. 1L) or mL/kg (i.e. 10 mL/kg)
  2. Document the amount of fluid ordered AND the rationale for not giving the full 30 ml/kg in a narrative note. CMS will currently accept any rationale given by the provider as long as it is explicitly stated. For example: CHF, ESRD, concern for fluid overload, adequate response to a lesser volume, etc.
• If BMI>30, can use Ideal Body Weight (IBW)
  • “BMI>30; using IBW of _ kg for sepsis”
  • MDCalc – BMI Calculator
  • MDCalc – Ideal Body Weight Calculator
• EMS fluid is considered part of the 30 mL/kg bolus. Document amount given by EMS and time.

After completion of the fluid bolus, document a perfusion reassessment. Use phrase “I have performed the perfusion reassessment” or include the following elements in a focused exam

Focused Exam

Focused Exam must include 5 of the following:

• Oxygen Saturation
• Capillary Refill
• Cardiopulmonary assessment
  • HR, rhythm, lung auscultation
• Peripheral Pulses
• Shock Index (“I’ve reviewed the shock index”)
• Skin color or condition (“cool and clammy”)
• Urine Output: exact volume not required (“diminished urine output”)
• Vital Signs: HR, RR, temp, BP

OR any one of the following:

• Central venous pressure
• Central venous oxygen
• Bedside cardiovascular ultrasound
• Passive leg raise or fluid challenge

And may be documented by another physician or provider (ex. admitting team)

Six Hour Bundle (Items to be completed within 6 hrs)

• Repeat lactic acid if initial is > 2 mmol/L
• Vasopressor for refractory hypotension – MAP<65 (SBP<90)
• If not already completed, document perfusion reassessment for persistent or refractory hypotension within 1 hour of bolus completion, or initial lactic acid > 4. Use phrase “I have performed the reperfusion assessment”.

Important Notes

• Patients that are excluded:
  • Age < 18 yo
  • Transferred to you from other hospital
  • Diagnosis of COVID-19 (principal or other)
  • Sepsis or septic shock due to a viral, fungal, or parasitic infection
  • Admitted to comfort care / hospice / palliative care within 6 hours of meeting sepsis criteria
  • Enrolled in a clinical trial for sepsis or septic shock during this hospitalization
  • Patients or surrogate refusing care (blood draw, cultures, antibiotics, etc.)
• Lactic acid elevation due to a non-infectious etiology (ex. seizure) is disregarded, but must be documented by the physician or provider.
• Requirement to use broad spectrum antibiotic was removed beginning July, 2021. Appropriate IV antibiotic selection is deferred to the treating physician or provider.
