rems_score: Rapid Emergency Medicine Score (REMS)

Description

Calculates the Rapid Emergency Medicine Score (REMS) to predict in-hospital mortality in non-surgical emergency department patients. The score is an adaptation of the APACHE II score but relies on only six readily available parameters: age, heart rate, respiratory rate, systolic blood pressure, Glasgow Coma Scale (GCS), and oxygen saturation.

Usage

rems_score(age_years, heart_rate, respiratory_rate, systolic_bp, gcs_score,
           oxygen_saturation)

Value

A list containing:

REMS_Score

The calculated total score (Range 0-26).

Mortality_Risk

Estimated mortality risk category.

Arguments

age_years

Numeric. Patient age in years.

heart_rate

Numeric. Heart rate in beats per minute.

respiratory_rate

Numeric. Respiratory rate in breaths per minute.

systolic_bp

Numeric. Systolic blood pressure in mmHg.

gcs_score

Numeric. Glasgow Coma Scale score (3-15).

oxygen_saturation

Numeric. Peripheral oxygen saturation (SpO2) percentage.

Examples

# Example 1: Low Risk
# 40yo, HR 80, RR 16, SBP 120, GCS 15, SpO2 98
# Score = 0

# Example 2: High Risk
# 70yo (+5), HR 120 (+2), RR 28 (+2), SBP 100 (0), GCS 12 (+2), SpO2 88 (+1)
# Score = 12
