Simplified Pulmonary Embolism Severity Index (sPESI)

Description

Calculates the Simplified PESI score to predict 30-day mortality in patients with confirmed pulmonary embolism (PE). The score uses 6 variables to stratify patients into Low Risk (score of 0) or High Risk (score >= 1), aiding in the decision for outpatient versus inpatient management.

Usage

simplified_pesi_score(age, cancer_history, chronic_cardiopulmonary_disease,
                      heart_rate, systolic_bp, oxygen_saturation)

Arguments

age	Numeric. Patient age in years. (> 80 years adds 1 point).
cancer_history	Numeric (0 or 1). History of cancer. (1 = Yes, +1 point).
chronic_cardiopulmonary_disease	Numeric (0 or 1). History of chronic cardiopulmonary disease. (1 = Yes, +1 point).
heart_rate	Numeric. Heart rate in beats per minute. (>= 110 bpm adds 1 point).
systolic_bp	Numeric. Systolic blood pressure in mmHg. (< 100 mmHg adds 1 point).
oxygen_saturation	Numeric. Arterial oxyhemoglobin saturation (%). (< 90% adds 1 point).

Value

A list containing:

sPESI_Score	The calculated total score (Range 0-6).
Risk_Category	Classification (Low Risk = 0, High Risk >= 1).
Est_30_Day_Mortality	Estimated 30-day mortality risk percentage.
Recommendation	Suggested management strategy.

Examples

# Example 1: Low Risk
# 50yo, No Hx, HR 80, SBP 120, SpO2 98%
# Score = 0
simplified_pesi_score(50, 0, 0, 80, 120, 98)

# Example 2: High Risk
# 85yo (+1), HR 115 (+1), No other factors
# Score = 2
simplified_pesi_score(85, 0, 0, 115, 120, 95)
