Infant Scalp Score

Description

Calculates the Infant Scalp Score (Greenes & Schutzman) to stratify the risk of traumatic brain injury (TBI) in infants (<2 years) with isolated scalp hematomas. The score helps guide the decision between observation and neuroimaging (CT).

Usage

infant_scalp_score(age_months, hematoma_size, hematoma_location)

Arguments

age_months	Numeric. Patient age in months. 0-2 mo: +3 pts. 3-5 mo: +2 pts. 6-11 mo: +1 pt. >=12 mo: 0 pts.
hematoma_size	String. Size/Character of the hematoma. "none": No hematoma (0 pts). "small": Barely palpable / <1 cm (1 pt). "medium": Easily palpable / 1-3 cm (2 pts). "large": Boggy / >3 cm (3 pts).
hematoma_location	String. Location of the hematoma. "frontal": 0 pts. "occipital": 1 pt. "parietal_temporal": 2 pts.

Value

A list containing:

Infant_Scalp_Score	The calculated risk score (Range 0-8).
Risk_Category	"Low Risk" (Score < 4) or "High Risk" (Score >= 4).
Recommendation	Guidance on the need for head CT.

Examples

# Example 1: High Risk
# 2 month old (+3), Small hematoma (+1), Parietal (+2)
# Score = 6
infant_scalp_score(2, "small", "parietal_temporal")

# Example 2: Low Risk
# 9 month old (+1), Medium hematoma (+2), Frontal (0)
# Score = 3
infant_scalp_score(9, "medium", "frontal")
