Overview
Neutropenic fever is defined as one oral temperature of ≥38.3°C (101°F) or a temperature of ≥38.0°C (100.4°F) for over one hour. Neutropenia is defined as an absolute neutrophil count (ANC) <500 cells/mm3 or an ANC that is expected to become less than 500 cells/mm3 over the next 48 hours. Profound neutropenia is defined as an ANC <100 cells/mm3. Patients with functional neutropenia have a qualitative abnormality of neutrophil functions despite a normal or elevated ANC, as seen in hematological malignancy, and are at increased risk of infections similarly to patients with low ANC.[1]

Life Threatening Causes
Life-threatening causes include conditions which may result in death or permanent disability within 24 hours if left untreated.

Day 1: Initial Management of Patients With Neutropenic Fever
Characterize the symptoms: Symptom suggestive of neutropenic fever:

Consider the diagnosis of neutropenic fever POTENTIALLY LIFE THREATENING | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Obtain a detailed history: ❑ History of any symptom of infections and inflammation of

❑ History of any recent exposure to infections | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Examine the patient: ❑ Search for signs of infections at
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Order laboratory tests (routine): ❑ CBC with
❑ BMP
❑ Urinalysis Order additional tests (not routine and order if clinically indicated):
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Do a risk assessment using MASCC risk Index: (MANDATORY)
| ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Low risk patients: ❑ MASCC score ≥21 or ❑ Expected brief neutropenia (≤7 days) | High risk patients: ❑ MASCC score <21 or ❑ Expected prolonged neutropenia (>7 days) Patients who do not strictly fulfill the criteria for being at low risk Afebrile neutropenic patients with new signs or symptoms suggestive of infection | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Administer oral or IV empirical broad-spectrum antibiotic therapy (URGENT): ❑ Ciprofloxacin + Amoxicillin-clavulanate | Hospitalize the patient | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Consider continuing with inpatient IV broad-spectrum antibiotics: ❑ Inability to tolerate oral medications | Administer IV empirical antipseudomonal antibiotic monotherapy (URGENT): ❑ Cefepime | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Inpatient monitoring: Monitor for recovery, adverse drug effects, secondary infections and development of drug-resistance with | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Consider discharge with outpatient oral broad-spectrum antibiotics: ❑ Ability to tolerate oral medications | Add vancomycin to the initial empirical antibiotic monotherapy for: ❑ Suspected Catheter related infection Consider modifying the initial empirical antibiotic monotherapy for:
or
| |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Outpatient monitoring: ❑ Monitor for recovery, adverse drug effects, secondary infections and development of drug-resistance with
❑ Ensure 24 hours a day and 7 days a week access to the appropriate medical care

Days 2 to 4: Management of Low Risk Patients With Neutropenic Fever After Day 1 Management
Low risk patients | |||||||||||||||||||||||||||||||||||||||||||||||||
Unexplained fever after day 1 | Clinically or microbiologically documented infection during day 1 | ||||||||||||||||||||||||||||||||||||||||||||||||
❑ Persistent or recurrent fever and/or ❑ Clinically unstable | ❑ Responding to initial empirical therapy and/or ❑ Cultures negative | Modify antibiotics according to culture results and/or infection site:

Inpatient management: Order: Consider noninfectious causess: | Continue the initial oral or IV broad-spectrum antibiotics until: ❑ ANC is >500 cells/mm3 and rising Outpatient management:
❑ Monitor the patients for recovery, adverse drug effects, secondary infections and development of drug-resistance with
❑ Ensure 24 hours a day and 7 days a week access to the appropriate medical care

❑ Continue antibiotics
and
| ❑ Consider re-examination and re-imaging studies (CT, MRI) for new or worsening sites of infection ❑ Consider culturing, biopsy, or draining sites of worsening infection ❑ Consider reviewing antibiotic coverage for adequacy of dosing and spectrum ❑ Consider adding empirical antifungal therapy ❑ Broaden antimicrobial coverage for hemodynamic instability | ||||||||||||||||||||||||||||||||||||||||||||||||

Preemptive antifungal management: Order: ❑ CT chest and sinuses
❑ Serial serum b-(1-3)-D glucan test for
❑ Serial serum galactomannan test for
Administer antifungal therapy if: Withhold antifungal therapy if: | Empirical antifungal therapy with anti-mold therapy: ❑ Echinocandin ❑ Voriconazole ❑ Amphotericin B preparation | Empirical antifungal therapy: ❑ Consider switch to a different class of mold active antifungal | |||||||||||||||||||||||||||||||||||||
Do's
- Modify the antibiotic regimens depending on the clinical picture and the epidemiology of infections in the area and the hospital where the patient is being treated at.
Don'ts
- Don't measure the temperature of the patient in the axillary area because it is not as specific as if it was taken orally.
- Don't measure the temperature of the patient rectally to avoid contaminating the skin and soft tissues of the rectal area.
