MASCC Risk Index for Febrile Neutropenia

Description

Calculates the Multinational Association for Supportive Care in Cancer (MASCC) Risk Index to identify low-risk patients with febrile neutropenia. A score >= 21 indicates a low risk of complications, suggesting that the patient may be eligible for outpatient management and/or oral antibiotics.

Usage

mascc_risk_index(burden_severity, hypotension_present, copd_history, tumor_type,
                 previous_fungal_infection, dehydration_present, outpatient_status,
                 age)

Arguments

burden_severity	String. Burden of febrile neutropenia illness. Options: "none_mild" (+5 pts), "moderate" (+3 pts), "severe" (0 pts).
hypotension_present	Numeric (0 or 1). Presence of hypotension (Systolic BP < 90 mmHg). (1 = Yes, 0 pts; 0 = No, +5 pts).
copd_history	Numeric (0 or 1). History of Chronic Obstructive Pulmonary Disease. (1 = Yes, 0 pts; 0 = No, +4 pts).
tumor_type	String. Type of malignancy. "solid" or "hematologic".
previous_fungal_infection	Numeric (0 or 1). Previous fungal infection (only relevant for hematologic malignancy). (1 = Yes). Note: Solid tumor OR (Hematologic malignancy with NO previous fungal infection) adds +4 pts.
dehydration_present	Numeric (0 or 1). Dehydration requiring parenteral fluids. (1 = Yes, 0 pts; 0 = No, +3 pts).
outpatient_status	Numeric (0 or 1). Patient status at onset of fever. (1 = Outpatient, +3 pts; 0 = Inpatient, 0 pts).
age	Numeric. Patient age in years. (< 60 years adds +2 pts).

Value

A list containing:

MASCC_Score	The calculated total score (Range 0-26).
Risk_Category	"Low Risk" (>= 21) or "High Risk" (< 21).
Recommendation	Clinical guidance regarding disposition and therapy.

Examples

# Example 1: Low Risk
# Mild symptoms, No hypotension, No COPD, Solid tumor, No dehydration, Outpatient, Age 45
# Score = 5 + 5 + 4 + 4 + 3 + 3 + 2 = 26
mascc_risk_index("none_mild", 0, 0, "solid", 0, 0, 1, 45)

# Example 2: High Risk
# Severe symptoms, Hypotension, Heme malignancy with fungal hx, Inpatient, Age 70
# Score = 0 + 0 + 4 + 0 + 3 + 0 + 0 = 7
