Neutropenic Precautions
Neutropenia is a reduction in circulating neutrophils — the primary defenders against bacterial and fungal infection. Chemotherapy-induced neutropenia is the most common cause in oncology. Nurses must understand ANC thresholds, implement precautions, and recognize febrile neutropenia as an oncologic emergency.
Educational use only. This material supports nursing education and exam review. It is not medical advice and is not a substitute for clinical judgment, institutional policy, or medical direction. Always follow facility protocols and current provider orders.
Febrile neutropenia = oncologic emergency. Fever (≥38°C / 100.4°F) + ANC <500 requires blood cultures AND broad-spectrum IV antibiotics within 60 minutes. Untreated febrile neutropenia can progress to septic shock within hours.
Absolute Neutrophil Count (ANC) Interpretation
ANC formula: ANC = WBC × (% neutrophils + % bands) ÷ 100. Example: WBC 2.0 × (40% segs + 10% bands) ÷ 100 = ANC of 1,000.
| ANC Range | Classification | Infection Risk | Precautions |
|---|---|---|---|
| ≥1,500/mm³ | Normal | Normal | Standard precautions |
| 1,000–1,499/mm³ | Mild neutropenia | Slightly increased | Hand hygiene education, avoid known sick contacts |
| 500–999/mm³ | Moderate neutropenia | Moderate — begin precautions | All standard neutropenic precautions; avoid crowds; no fresh flowers or plants |
| <500/mm³ | Severe neutropenia | HIGH — major precautions | Private room preferred; strict hand hygiene all visitors; neutropenic diet; no fresh produce; mask per protocol |
| <100/mm³ | Profound neutropenia (agranulocytosis) | CRITICAL — extremely vulnerable | All above + HEPA-filtered room if available; limit invasive procedures; consider reverse isolation protocols |
Standard Neutropenic Precautions
Hand hygiene
- ✦All staff and visitors wash hands with soap and water OR alcohol hand rub before entering room and before/after patient contact
- ✦Patient should also perform hand hygiene frequently
- ✦Nails: short, no artificial nails for staff
Room environment
- ✦Private room preferred (single-occupancy) — especially for ANC <500
- ✦HEPA filtration or positive-pressure room for profoundly neutropenic or BMT patients
- ✦No fresh flowers or live plants (harbor Aspergillus and Pseudomonas)
- ✦No stagnant water (e.g., no water pitchers left sitting >24 hrs)
Visitor restrictions
- ✦No visitors with active infections, recent vaccinations with live virus, or known exposure to communicable disease
- ✦Limit number of visitors to reduce pathogen exposure
- ✦All visitors must perform hand hygiene before entering
- ✦Children may be restricted per institutional policy
Staff precautions
- ✦Avoid assigning nurses who have active respiratory infections
- ✦No rectal temperatures, suppositories, enemas, or rectal examinations (disrupts mucosal barrier)
- ✦Minimize invasive procedures — use smallest gauge needle when possible
- ✦CVAD care using strict aseptic technique — CVADs are common infection entry points
Neutropenic Diet
AVOID (high-bacterial-load foods)
- ✗Raw or undercooked meat, poultry, fish, eggs
- ✗Raw fruits and vegetables (especially leafy greens, sprouts, melons)
- ✗Unpasteurized dairy products, soft cheeses
- ✗Deli meats and cold cuts (unless heated to steaming)
- ✗Buffet or cafeteria foods that have been sitting out
- ✗Salad bars and raw salad dressings (blue cheese, caesar)
- ✗Unwashed fresh produce
- ✗Well water (possible bacterial contamination)
SAFE (low-bacterial-load foods)
- ✓Fully cooked meats, poultry, fish (165°F internal temp)
- ✓Pasteurized dairy products, hard cheeses
- ✓Cooked and canned vegetables and fruits
- ✓Pasteurized fruit juices
- ✓Commercially packaged foods
- ✓Bread, crackers, cooked grains
- ✓Tap water (municipally treated is acceptable)
- ✓Foods prepared and eaten immediately (no leftovers after 2+ hours)
Note: Some institutions have liberalized neutropenic diet guidelines as evidence supporting strict restriction has been limited for moderate-risk patients. Follow your institutional policy.
Febrile Neutropenia Protocol
Definition: Fever ≥38°C (100.4°F) × 1 hour OR ≥38.3°C (101°F) once + ANC <500 (or expected to drop below 500)
G-CSF (Colony-Stimulating Factors)
| Drug | Use | Nursing Notes |
|---|---|---|
| Filgrastim (Neupogen) | Short-acting G-CSF — stimulates neutrophil production from bone marrow. Primary or secondary prophylaxis for chemotherapy-induced neutropenia. | Subcutaneous injection. Common side effect: bone pain (from marrow expansion) — treat with acetaminophen. Do NOT give within 24 hrs before or after chemotherapy. |
| Pegfilgrastim (Neulasta) | Long-acting G-CSF — given once per chemotherapy cycle (vs. daily filgrastim). On-body injector device available. | Bone pain is common. Same contraindication — not within 24 hrs of chemo. |
| Sargramostim (Leukine) | GM-CSF — stimulates both neutrophil and monocyte production. Used in BMT/SCT engraftment. | May cause capillary leak syndrome (dyspnea, edema). Fever and myalgia are common. |
