news_score: National Early Warning Score (NEWS)

Description

Calculates the National Early Warning Score (NEWS) to standardize the assessment of acute illness severity. The score is based on seven physiological parameters: Respiratory Rate, Oxygen Saturation, Supplemental Oxygen use, Temperature, Systolic BP, Heart Rate, and AVPU score.

Usage

news_score(respiratory_rate, oxygen_saturation, any_supplemental_oxygen,
           temperature_c, systolic_bp, heart_rate, avpu_score)

Value

A list containing:

NEWS_Score

The calculated total score (Range 0-20).

Risk_Category

Classification of clinical risk (Low, Medium, High).

Response_Level

Recommended clinical response urgency.

Arguments

respiratory_rate

Numeric. Respiratory rate in breaths per minute.

oxygen_saturation

Numeric. Oxygen saturation percentage (SpO2).

any_supplemental_oxygen

Numeric (0 or 1). Is the patient receiving supplemental oxygen? (1 = Yes, +2 points).

temperature_c

Numeric. Body temperature in degrees Celsius.

systolic_bp

Numeric. Systolic blood pressure in mmHg.

heart_rate

Numeric. Heart rate in beats per minute.

avpu_score

String. Level of consciousness: "alert", "voice", "pain", "unresponsive". Any response other than "alert" scores 3 points.

Examples

# Example 1: Low Risk
# RR 18, SpO2 98, No O2, Temp 37, SBP 130, HR 70, Alert
news_score(18, 98, 0, 37.0, 130, 70, "alert")

# Example 2: High Risk
# RR 26 (+3), SpO2 90 (+3), On O2 (+2), Temp 39 (+1), SBP 100 (+1), HR 120 (+2), Verbal (+3)
# Score = 15
