Q

STEP 1

  • *5 Step Treatment Approach**
  • *FEBRILE NEUTROPENIA**
A

WITHIN 15 MINUTES

A) Assume Bacterial infection
fever is often the ONLY sign of infection

B) **C**ollect SAMPLES

  • *CBC + Leukocyte Differential Count** = ANC
  • *>** 2 sets of Blood Cultures

C) Perform Systemic patient Assessment
maximize chances of determining SITE of infxn / organism

OUTPATIENT TREATMENT
PCN ALLERGY

Step 5b: Reassess Therapy for Outpatient
Febrile Neutropenia

A

Goal: Defervesence within 3 days of ABx infection
if failure –> RE-ADMIT to hospital

CIPROFLOXACIN** or **LEVOFLOXACIN

Step 3: ANC CALCULATION

Absolute Neutrophil Count (ANC) < 500 cells/mm3
Mature: PMN or SEGs // Immature: BANDS

Percent:
Total WBC x (%PMN/100 + %BANDS/100)

Total Number:
(PMNs + Bands) x 1,000

A

1 Anti-Pseudomonal B-Lactam

STEP 2

  • *5 Step Treatment Approach**
  • *FEBRILE NEUTROPENIA**
A

2 - Select Empiric Antimicrobial Therapy

Recommendation:

  • *ALL PATIENTS** should recieve an INITIAL IV DOSE
  • *ASAP = within 1 hour**

Most common infection = translocation across intestine
20-30% bacteremia

Goal is to Cover:
MOST COMMON (Gram POS) & MOST VIRULENT (Gram NEG)

Step 4:
ID Candidates for OUTPATIENT Treatment

Carefully selected patients that are at:
low risk for medical complications –> ORAL ABx

17
Q

What to do if….
Febrile for 2 days + Negative Cultures

  • *Step 5a: Reassess Therapy for INPATIENT**
  • *Febrile Neutropenia**
A

Febrile for 2 days + Negative Cultures
AND
ANC > 500
VVV
MAY DISCONTINUE THERAPY

18
Q

What to do if….
PERSISTANT FEVER
but, stable & no site of infxn detected

  • *Step 5a: Reassess Therapy for INPATIENT**
  • *Febrile Neutropenia**
A

PERSISTANT FEVER
but, stable & no site of infxn detected
VVV
CONTINUE THERAPY** until **ANC > 500
+
keep looking for infxn source

19
Q

Febrile Neutropenia

DEFINITION

A

FEVER
Single reading > 38.3*C (101*F)
or a > 38*C sustained over an hour

  • *SEVERE NEUTROPENIA**
  • *ANC < 500 cells/mm3**

Seen:
CHEMOTHERAPY START** within **6 WEEKS

20
Q

Febrile Neutropenia PROPHYLAXIS

What to give if….
Allogenic Hematopoeietic Cell Transplant = HSCT?
&
SEROPOSITIVE for HSV +/- VZV

A

AntiBACTERIAL:
CIPROFLOXACIN or LEVOFLOXACIN

AntiVIRAL
ACYCLOVIR or VALACYCLOVIR
+ Annual Flu Shot

AntiFUNGAL
FLUCONAZOLE
for CANDIDA - HSCT

21
Q

When to add VANCOMYCIN?

Step 2: Empiric ABx Therapy
Febrile Neutropenia

A

HIGH RISK PATIENTS
SEPTIC (hemodynamically Unstable) = ↑Mortality risk
Suspected:
PNEUMONIA
CRSBI (Catheter related infxn)
Skin or Soft-Tissue Infxn
H/o MRSA infxn or colonization

  • Addition of VANC (for gram POS) is NOT associated w/ clinical benefit & may promote RESISTANCE
  • DO NOT USE PIP/TAZO w/ VANCOMYCIN**
